The dingo ( Canis familiaris or Canis familiaris dingo or Canis lupus dingo or Canis dingo ) is a native Australian wild dog. Taxonomic status is disputed. The first British colonists who arrived founded settlements in Port Jackson in 1788 and recorded dingo living there with native Australians. Although dingo is in the wild, it deals with humans but has not been raised selectively like other pets. It is a medium sized canid that has a sleek and strong body that is adjusted for speed, agility, and stamina. The three colors of Dingo's main coat are described as mild ginger (or brown), black and brown, or creamy white. The head is the widest part of the dingo, wedge-shaped, and large in proportion to the body. The dingo skull is different from domestic dogs with larger palatal width, longer pulpit, shorter skull height, and wider sagittal peak. One can regard dingo as an ecotype or ecosystem that has adapted to Australia's unique environment. It is listed as a "Vulnerable Species" on the IUCN Red List due to a decrease in numbers caused by hybridization with domestic dogs.
Genetic studies show that dingo is closely related to the dogs of New Guinea singers, that their lineage is separate from the lineage that causes domestic dogs today, and their lineages can be traced back through the Malay Archipelago to Asia. In archaeological records, the earliest known remains of the dingo skeleton in Australia (from the Mandurah Cave in the Nullabor Plain, south-east Australia) dated 3,450 years before now (YBP), which led to widespread belief that dingo to sailors to Australia , 5,000 YBP. This comparison of early fossils with modern dingo shows that dingo morphology has not changed over the last 3,500 years. This suggests that there has been no artificial selection during this period and that the dingo represents the early form of the dog from 4,000-5,000 years ago. They have lived, reproduced, and undergone natural selection in the wild, isolated from other headers until the arrival of European settlers, producing a unique canid. Therefore, some scientists have argued that dingo should be recognized as a different taxon that should be classified with its original Latin name, Canis dingo . A recent genetic study shows that the lineage of dingo found today in the northwestern part of the Australian continent is separated from the dog lineage of New Guinea singers and the southeast dingo of 8,300 YBP, followed by a split between the dog lineage of New Guinea immigrants from the bloodline dingo southeast 7,800 YBP. The study proposes that there are two dingo migrations when sea level is lower and Australia and New Guinea form a land called Sahul that existed up to 6,500-8,000 years ago. Dingo is recognized as a native animal under the law of all Australian jurisdictions.
The Dingo distribution includes a variety of habitats, including temperate regions of eastern Australia, alpine moorlands in the eastern highlands, the arid desert of Central Australia, and tropical forests and North Australian wetlands. Dingos preys on mammals to large red kangaroo sizes, in addition to birds, reptiles, fish, crabs, frogs, insects, and grains. Dingo competitors include original quolls, introduced European red foxes and wild cats. Dingo packages usually consist of couples who are wed, their offspring from the current year and sometimes offspring from the previous year.
Livestock began to flourish throughout Australia from the early 19th century, which led to a conflict between dingo and sheep breeders. Sheep, and at lower levels of livestock, are easy targets for dingo. Pastors and government agencies supporting their industry have shot, trapped, and poisoned dingo or destroyed dingo pups in their nests. After two centuries of persecution, dingo or dingo-dog hybrids can still be found on most continents. Dingo plays an important role in the dreamtime stories of native Australians; However, it rarely appears in their cave painting when compared to the extinct thylacine.

Etymology
The name "dingo" comes from the Dharug language used by the Indigenous Australians in the Sydney area. The first British colonist to arrive in Australia in 1788 set up a settlement in Port Jackson and recorded the "dingo" that lived with the native Australians. The name was first recorded in 1789 by Watkin Tench in his Narration Expedition to Botany Bay :
The only pets they have are dogs, which in their language are called Dingo, and many resemble English fox dogs. These animals are equally shy of us, and attached to the natives. One of them is now owned by the Governor, and is quite well at peace with his new master.
Variants include "tin-go" for bitch, "din-go" for dogs, and "wo-ri-gal" for a big dog. Dingo has been given a different name in Indigenous Australia, including "boolomo", "dwer-da", "joogoong", "kal", "kurpany", "maliki", "mirigung", "noggum", "papa -inura ", and" wantibirri ". Some authors propose that there is a distinction between camp dingoes and wild dingo because they have different names among indigenous tribes. People from Yarralin, the Northern Territory often call the dingo who live with them me, , and those living in the desert ngurakin . They also use the name my name to refer to dingo and dog. New South Wales colonial settlers write using the dingo name only for camp dogs. It is proposed that in New South Wales camp camps only become wild after the collapse of aboriginal communities.

Taxonomy
The taxonomic classification of the dingo remains confusing and moot.
Nomenclature
The nomenclature provides the name to be used for the taxon, when it is recognized taxonomy as a different entity.
The dogs associated with the natives were first noted by Jan Carstenszoon in the Cape York Peninsula region in 1623. In 1699, Capt. William Dampier visited the now Western coast of Australia and noted that "... my people saw two or three animals savage like a wolf hungry, leaning like so many skeletons, to be anything but skin and bone... ".
In 1768, James Cook took the scientific discovery shipping command from England to New Holland, which was the name for Australia at the time. In 1770, his ship HMS Endeavor arrived at Botany Bay, now part of Sydney. The mission collected specimens and made notes to be brought back to the UK. Upon his return to England, Joseph Banks commissioned George Stubbs to produce paintings based on his observations, one of which was "Portrait of the Great Dog from New Holland" completed in 1772. In 1788, the First Fleet arrived at Botany Bay under the command of Australia's first colonial governor, Arthur Phillip , which makes a brief description and illustration in his journal about "New South Wales Dog". In 1793, the "New South Wales Dog" was classified by Friedrich Meyer as Canis dingo , based on illustrations. Johann Friedrich Blumenbach collected a collection of Cook's journey and in 1799 he classified "New Holland dog" as Canis familiaris dingo. In 1947, a proposal was made to change this classification after it was found that the "New Holland dog" Canis antarticus Kerr, 1792 had been set a year earlier in a lesser known work. Both Kerr and Meyer have based their classification on the illustrations of "New South Wales Dog", and therefore no specimen reference types are based on this.
In 1957, the International Commission for Zoological Nomenclature (ICZN) was asked to suppress the name Canis antarticus on the grounds that Canis dingo is a common name that has been used for 150 years. ICZN decides that Canis antarticus Kerr, 1792 must be suppressed and that Canis dingo Meyer, 1793 is the name to be used for dingo in its Opinion 451. The name is then entered in ICZN Official List and Name Index in Zoology . The name entered in the ICZN Authorized List is an available name, which is a "scientific name applied to animal taxon", although it does not specify whether or not the nickname is used as in the species or at the subspecific level, or even dropped if the name is regarded as synonymous of other species for taxonomic reasons.
In 2003, ICZN declared in its Revenue 2027 that "the name of wild species... is invalid because it was preceded by a name based on a domestic form." Additionally, ICZN places a taxi Canis lupus as a name preserved on an official list based on this opinion. The reason for doing this is that "The vast majority of wild progenitors and their domestic derivatives share the same name, but in 17 cases considered.... wild and domestic forms have been called separately and this has created confusion." This opinion means that the name of the domestic dog ( Canis familiaris ) is not preferred on behalf of the wolf ( Canis lupus ) when researchers explore the relationship between two taxa.
Taxonomy debate
Taxonomy classifies shared organisms that have common characteristics. The nomenclature does not specify the rank to be assigned to a collection of animals, only its official name. Therefore, zoologists are free to propose what groups of animals possess similar characteristics that may be possessed by taxon. In the third edition of the World Mammal Species published in 2005, W. Christopher Wozencraft mammalogist is listed under the Canis lupus wolf he proposed into two subspecies: i> Linneaus, 1758 [domestic dog] "and" dingo Meyer, 1793 [domestic dog] ", with the comment" Including domestic dogs as subspecies, with separate temporary dingo - artificial variants made by domestication and selective breeding Although this may stretch the concept of subspecies, it maintains the correct allocation of synonyms. "
This classification by Wozencraft is hotly debated by zoologists. Mathew Crowther, Stephen Jackson and Colin Groves disagree with Wozencraft and argue that under ICZN Opinion 2027, the implication is that domestic animals can not become subspecies. Crowther, Juliet Clutton-Brock and others argue that since dingo is distinct from wolves by behavior, morphology, and that dingo and dogs do not fall genetically in an existing wolf clade, dingo must be considered a different taxon. Canis dingo . Jackson and Groves consider the Canis familiaris as a taxonomic synonym for the Canis lupus wolf with both rankings at the species level. They also disagree with Crowther, based on the overlap between dogs and dingo in their morphology, in their ability to easily hybridize each other, and that they show signs of domestication by both having smaller cranial capacities than their ancestors, wolves. Given that Canis familiaris Linnaeus, 1758 had priority over Canis dingo Meyer, 1793, they regarded dingo as a junior taxonomy synonym for dogs Canis familiaris ie dogs and dingo are two names for the same taxi Canis familiaris ). Gheorghe Benga and others support dingo as a subspecies of dogs, so that Canis familiaris dingo with domestic dogs becomes a subspecies Canis familiaris familiaris .
Although the dingo is in the wild, it deals with humans but has not been selectively cultivated similar to other pets. Therefore, his status as a pet is unclear. Whether dingo is a wild or pet species not clarified from the original description of Meyer, translated from the German language ambiguously reads:
It is unknown if it is the only dog ​​species in New South Wales, and if it is also still to be found in the wild; However, so far it seems to have lost a bit of the wild conditions; In addition, no different varieties were found.
By 2014, the whole genome sequencing indicates that dogs are not descended from the remaining gray wolves, the dog's ancestors are extinct, and the dingo falls in a dog clone. In 2015, Australian Mammalian Taxonomy considers Dingo as Canis familiaris . In 2017, a review of the latest scientific information proposes that the Dingo and New Guinea singers are domestic Canis familiaris Linnaeus 1758. By the end of 2017 Australian Faunal Directory The Australian Government lists Dingo under Canis familiaris Linnaeus 1758.
Lineage
Full-genome sequencing has been used to survey "... an allegedly ancient semi-domestic dog race, Basenji and dingo." By 2016, a study based on a whole series of genomes suggests that dogs are genetically distinct subspecies of gray wolves and derived from extinct ghost populations of extinct Ends, dogs and dingo not separate species, and in accordance with previous studies that dingo and Basenji are considered as basal members of domestic dog cladding. "The term basal refers to the line that deviates earlier in group history... and lies in branches that originate near the ancestors with the group." The study found evidence for a 0.3% gene flow of mitochondrial DNA into the dingo lineage of the Qinghai Tibetan wolf population. The National Kennel Board of Australia recognizes the standards of dingo breeds in its Hounds group.
Archaeological records show that the earliest remains of the dingo framework in Australia date from 3,450 years before (YBP) from the Mandurah Cave in the Nullabor Plain, southeast of Western Australia; 3,320 YBP from Woombah Midden near Woombah, New South Wales; and 3,170 YBP from Fromme's Landing on the Murray River near Mannum, South Australia. Dingo bone fragments are found in stone shelters located in Mount Burr, South Australia in layers originally dated 7,000-8,500 YBP. The excavations then indicate that the level has been interrupted, and the dingo remains "likely to move to the previous level." The earliest Dingo remains in Torres Straits currently to 2,100 YBP. In New Guinea, the earliest dog bone of 2,500-2,300 YBP from Caution Bay near Port Moresby but no remnants of the ancient New Guinea Lions found. This early Australian dingo fossil spawned a widely held belief that the first dingo arrives in Australia, 5,000 YBP with sailors. By comparison with these earliest fossils, dingo morphology has not changed over the last 3,500 years. This suggests that there has been no artificial selection during this period and that the dingo represents the early form of the dog from 4,000-5,000 years ago. They have lived, reproduced, and undergone natural selection in the wild, isolated from other headers until the arrival of European settlers, producing a unique canid. Therefore, it is said by some scientists that dingo should be recognized as a different taxon Canis dingo .
At the end of the final glacial maximum and sea level rise, Tasmania became separated from the Australian mainland 12,000 YBP, and New Guinea 6,500-8,500 YBP by a puddle of Sahul Shelf. No remains are found in Tasmania, therefore Dingo is estimated to arrive in Australia between 3,500-12,000 YBP. To reach Australia via the Malay Islands even at the lowest sea level of the Last Glacial Maximum, a journey of at least 50 km (30 miles) through the open sea between ancient Sundanese and Sahul is required, indicating that the dingo arrives to Sahul by boat.
The haplotype (haploid genotype) is a group of genes within an organism inherited from a single parent. All the dingo sequences studied the A29 haplotype mDNA exhibit, which is in the Clade A haplog group representing 70% of domestic dogs. The evidence shows that haplotypes were introduced from East Asia or Southeast Asia through the islands of the Malay archipelago and entered Australia. Haplotype A29 is one of the few domestic dog mDNA haplotypes brought to the Malay Archipelago but only A29 reaches the Australian mainland. The A29 haplotype mDNA, or haplotype one step mutation step, is found in all Australian dogs and New Guinea Singing Dogs so far studied, showing offspring from common female ancestors.
In 2011, a study of male dingo lineages using Y chromosome DNA (yDNA) as a genetic marker was performed for 338 Australian dogs, Singing Dog New Guinea, and village dogs from the Malay Archipelago. Balinese dogs support the arrival of their ancestors with Austronesian expansion and other domestication arrivals of 3-4,500 YBP. The data confirms that dingo carries a unique yDNA haplogroup (H60) and has been derived from the h5 ydNA haplogroup. Haplogroup H5 is not found in the village dogs of the Malay Archipelago but this is common in Taiwan. One H5 specimen from Taiwan is clustered with one H60 from Australia with an indication of a common male ancestor of 4-5,000 YBP and coinciding with the expansion of the Daic tribe in South China. The conclusion is there are 2 expansion of two types of dogs. South China produced the first ancient regional breed some 8,000 years ago. It was then dominated and replaced by the subsequent explosive expansion of various breeds of dogs that have genetically grown in Southeast Asia. In that case, the Dingo and Singing Dogs of Papua, which prioritize the dogs in the Malay Archipelago, will reflect the last remnants of previous ancient breeds.
The existence of a genetic subdivision in the dingo population has been proposed for two decades but has not been investigated. In 2016, a study compared DNA sequences using the entire mDNA genome (16,000 base pairs in length), and 13 DNA loci from the cell nucleus, taken from the dingo dog and the singer dog of New Guinea. Their mother's mDNA studies provide evidence that they form monophyletic clones (indicating that they all carry the same mutations that were inherited from the ancestors of women in the past). Dogs from China, Bali, and Kalimantan are not included in this clause. There are two different dingo populations in Australia based on mitochondrial and nuclear evidence. Dingo found today in the northwestern part of the Australian continent is estimated to have deviated 8,300 YBP, followed by the difference between the New Guinea singing dog from the 7,800 YBP southeastern dingo. Since the New Guinea singer's dog is closely related to the southeast dingo, this divergence is suspected to occur somewhere in Sahul (a land that once included Australia, New Guinea and some islands around it) that existed up to 6,500-8,000 years ago. The New Guinea singer's dog then becomes a different but closely related lineage. Dingo Fraser Island is unique as they cluster with the southeast dingo but show many alleles (gene expression) similar to the New Guinea singer dog, in addition to showing mixing signs with the northwestern dingo. These dates indicate that the dingo spread from Papua New Guinea to Australia via a land bridge at least twice. The lack of fossil evidence from northern Australia and Papua New Guinea can be explained by their tropical climate and acid soils, as there are generally some fossils found in the region. By 2017, a study of dingo in a wider area found that singing female New Guinea female singing was more closely associated with southeast dingo, and its male lineage was more closely related to dingo found throughout the continent, suggesting that the Dingo lineage has a complex history.
The lineage of dingo dogs and New Guinea can be traced back through the Malay Islands to Asia. Therefore, dingo is not a "wild dog" but a pet dog that has become wild. The human-dog relationship is fluid, and the classification of being "wild" or "domesticated" is completely difficult. They have adapted to survive without human assistance and are the only population of dogs known to maintain long-term independence from humans.
Description
Dingo is a medium sized canid with a sleek and strong body designed for speed, agility, and stamina. The head is the widest part of the body, wedge-shaped and large in proportion to the body. This skull is more like a gold wolf than a wolf or a coyote. Compared to the dog's skull, the dingo has a longer snout, longer carnassial teeth, longer, slimmer canine teeth, larger hearing baudia, a flatter skull with larger sagittal emblems and larger nuchal lines. In 2014, a study was conducted on a 20th century dingo specimen that could not be affected by later hybridization. Dingo skulls are found to be different relative to domestic dogs with larger palate widths, longer pulpits, shorter skull height, and wider sagittal peaks. Based on comparisons with dingo remnants found in Fromme's Landing, skulls and dingo skeletons have not changed over the last 3,000 years.
Captive dingoes are longer and heavier than wild dingo because they have access to better food and animal care. The average wild dingo male weighs 15.8 kg (35 pounds) and female 14.1 kg (31 pounds), compared to captive men 18.9 kg (42 pounds) and women 16.2 kg (36 pound). The average length of male wild dingo was 125 cm (49 inches) and female 122 cm (48 inches), compared with captive men 136 cm (54 inches) and women 133 cm (52 ​​â € <â € < ). The average dingo male stood at shoulder height of 59 cm (23 inches) and female 56 cm (22 inches), compared with men captive 56 cm (22 inches) and women 53 cm (21 inches). Dingo rarely carries excess fat and the wild ones feature an open rib. Dingo from northern and northwestern Australia is often larger than that found in central and southern Australia.
The three colors of Dingo's main coat are described as mild ginger (or brown), black and brown, or creamy white. Ginger color ranges from deep rust to pale cream and can be found in 74% of dingo. There are often small white marks at the end of the tail, feet, and chest but no large white patches. Some do not show white tip. Dingo black and brown has a black coat with snout, chest, abdomen, legs and feet are brown and can be found in 12% of dingo. Solid white can be found in 2% of dingo and 1% solid black. Color coat with sable, ticking, or dappled shows some hybridization and can be found in 12% of dingo. There are only 3 genes that affect the color of the feathers in the dingo compared to 9 genes in domestic dogs. The ginger color is dominant and carries three other main colors - black, brown and white. White dingoes breed true, and black and brown dingoes breed true; when this crossed the result is sandy color. The coat is not greasy, nor does it have a dog-like smell. Dingo has a single mantle in the tropical north of Australia and a double thick coat in the cold mountains to the south, the lower layer being a gray wolf color.
Dingo's tail is flat, tapered after mid-length and not curved over the back but done low. The ears are erect and high on the skull. The eyes are triangular (or almond) and dark brown with dark edges. When walking, the dingo rear foot step is in line with the front foot, and it has no dewclaws. Dingo in the wild lives between 3-5 years with only 7-8 years. Some have recorded up to 10 years. In captivity dingo live between 12-14 years. Dingo is similar to the singing of New Guinea dogs in morphology apart from higher dingo altitudes in the withers.
Adaptation
Hybrids, distributions, and habitats
Insects like wolves are large carnivorous groups that are genetically intimately linked because their chromosomes are number 78, therefore they can potentially crosslink to produce fertile hybrids. In the wild Australia there are dingo, wild dogs, and crossings of both that produce dingo-dog hybrids. Much of the research that sees dingo distribution focuses on the distribution of dingo-dog hybrids instead.
Dingoes occurred throughout the Australian mainland before the settlement of Europe. Dingo is not found in the Tasmanian fossil record, so they arrived in Australia after Tasmania separated from the mainland due to rising sea levels. The introduction of agriculture reduced the distribution of dingo, and by the early 1900s a large guardrail, including the Dingo Fence, excluded them from sheep grazing areas. Land acquisition, poisoning, and trapping led to the extinction of dingo and hybrids from most of their previous reaches in southern Queensland, New South Wales, Victoria and South Australia. Today, they are absent from most of New South Wales, Victoria, the southeastern third of South Australia, and the southwestern tip of Western Australia. They are rare in eastern Western Australia and adjoining areas of the Northern Territory and South Australia. They are considered common throughout the continent.
Dingo can be considered as ecotype or ecospecies that have adapted to Australia's unique environment. Current distribution of dingo is spread over a wide range of habitats, including temperate regions of eastern Australia, alpine moorlands in the eastern highlands, the arid desert of Central Australia, and tropical forests and North Australian wetlands. Occupation, and adaptation to, this habitat may have been aided by their relationship with indigenous Australians.
Prey
The twenty-year study of diet doo is done throughout Australia by federal and state governments. It examines a total of 13,000 stomach contents and stool samples. For stool samples, it is possible to define fox and wildcat matching tracks and exclude these samples in the study, but it is not possible to distinguish between traces left by dingo from dingo or wild dogs. The study found that these canines predated 177 species represented by 72.3% of mammals (71 species), 18.8% of birds (53 species), 3.3% vegetation (1.8%), 1.8% reptiles (23 species) , and 3.8% of insects, fish, crabs and frogs (28 species). The relative proportions of prey are almost identical throughout Australia, in addition to more birds eaten in the north and southeast coasts, and more lizards in Central Australia. About 80% of the food consists of 10 species: red kangaroos, swamp wallabies, cows, black rats, geish swans, common hairbrushes, long-haired mice, agile wallabies, European rabbits and common wombats. Of the mammals eaten, 20% can be considered large.
However, the relative proportions of the size of the predatory mammals vary across regions. In the tropical Northern Territory coastal area, agile wallabies, soft and moody rats make up 80% of the food. In Central Australia, rabbits have become a substitute for native mammals, and during drought, cattle carcasses provide most of the food. In Barkly Tableland, no rabbits or native species dominate the diet, except for the long-haired mice that make up plagues every 9 years. In the Fortescue River area, large red kangaroos and the euro dominate food because there are some small mammals in this area. On the Nullarbor Plain, rabbits and red kangaroos dominate the diet, and twice as many rabbits are eaten as red kangaroos. In Australia's eastern Australian mountains, wallaby swamps and red-necked wallabies dominate the diet on the lower slopes and wombats on higher slopes. Possum is generally eaten here when it is found on the ground. In the dingo beach area explore the beach to wash fish, seals, penguins and other birds.
Dingoes drink about a liter of water every day in summer and half a liter in the winter. In dry areas during the winter, dingo can live from the fluid in the body of its prey, provided that the number of prey sufficient. In the arid Central Australia, weaned children draw most of their water from their food. There, female water regurgitation for puppies was observed. During breastfeeding, imprisoned females do not have higher water requirements than usual, because they consume the urine and kidure of children and therefore recycle water and keep the nest clean. Tracked dingo in the Strzelecki Desert regularly visits the water spots every 3-5 days, with two dingo that survive 22 days without water during winter and summer.
Hunting behavior
Dingo, hybrid dingo and wild dogs usually strike from the back as they chase their prey. They kill their prey by biting the throat, which destroys the trachea and major blood vessels in the neck. The size of a hunting pack is determined by the type of targeted target, with large packages set up to help hunt down large prey. Large prey can include kangaroos, cows, water buffalo and wild horses. Dingo will assess and target prey based on the ability of the prey to inflict damage to the dingo. Large kangaroos are the most commonly killed prey. His main tactic was to look at kangaroos, make up for it, then kill him. Dingo usually hunts large kangaroos by bringing dingo leads chasing mines toward their teammate's path, which skillfully cuts corners in romp. Kangaroos become exhausted and then killed. This same tactic is used by wolves, African hunting dogs, and hyenas. Another tactic shared with African hunting dogs is the relay chase until the prey is over. A pack of dingo is three times more likely to drop a kangaroo than an individual because the murders are committed by people who follow the main pursuers, who also become exhausted. There are two patterns from the final stages of attack. An adult kitten or teen is bitten on the back leg of the hind leg to slow it down before the attack to the throat. A small adult female or teenager is bitten on the neck or back by a dingo that runs next to them. In one of the areas of Central Australia, dinging hunt kangaroos by hunting them down to a wire fence where they become temporarily unable to move. The biggest red male kangaroos tend to ignore dingo, even when dingo hunts the younger and younger males. A large eastern gray kangaroo manages to resist an attack by a single dingo that lasts for over an hour. Wallabies are hunted in a manner similar to kangaroos, the difference being that a single dingo will hunt using scents rather than sight and hunting may last for several hours.
Dingo packets can attack young cows and buffalo but never healthy, mature adults. They focus on the sick or the young wounded. His tactics include harassing a mother with a young child, panicking herds to separate adults from young, or watching the flock and looking for unusual behaviors that might be exploited. One 1992 study in the Fortescue River area observed that cows would retain their calves by rotating around the calves or aggressively filling dingo. In one study of 26 approaches, 24 of them by more than one dingo and only 4 resulted in the calves being killed. Dingo often revisit carrion. They do not touch fresh cattle carcasses until most of them are skin and bones, and even when they are many, they still prefer to hunt kangaroos. Of 68 sheep pursuits, 26 sheep were seriously injured but only 8 were killed. Dingo dogs can run faster than sheep and sheep helpless. However, dingo in general seems unmotivated to kill sheep, and in many cases just jump with the sheep before turning to chase the other sheep. For those who kill and consume sheep, there are still a large number of kangaroos in their food, showing once again the preference for kangaroos.
Lone dingoes can lower the rabbit, but more successfully by targeting a kitten near a rabbit warrens. Dingo will pick up young birds or young birds, in addition to birds that roam and therefore can not fly. In the coastal wetlands of northern Australia, dingo depends on a magpie goose for most of their food and a single dingo will sometimes distract them while a white-breasted sea eagle makes the killings too heavy to take away, with dingo then drove the sea eagle. They will also scavenge fallen prey from the platform of sea eagles. Lone dingoes can hunt small rodents and grasshoppers on the grass by using their sense of smell and hearing, then pounce on them with their forepaws.
Competitors
Dingo and their hybrids co-exist with Quoll native people. They also occur simultaneously in the same region as the red foxes and European wildcat introduced, but little is known about the relationship between the three. Dingo and their hybrids will repel foxes from water sources and occasionally eat wild cats. Dingo can be killed by buffalo and cattle and kick them, from snake bites, and predation on their children with a wedge tail eagle.
Communications
Like all domestic dogs, dingoes tend toward phonetic communication. However, unlike domestic dogs, dingoes howl and whine more, and bark less. Eight voice classes with 19 sound types have been identified.
Bark
Compared to most domestic dogs, the skin is short and single-horned dingo, and is rarely used. Barking was observed to form only 5% of the vocalizations. Barking dogs are always different from barking wolves. Australian Dingo skin mainly attacks the sound or mixture of atonal and tonal sound. In addition, barking is almost exclusively used to warn. Warn-barking in homotypical sequences and some sort of "warn-howling" in heterotypical sequences has also been observed. Skin-howling begins with a few barks and then fades into an ups and downs and may (similar to cough) be used to warn puppies and pack members. In addition, dingoes emit a kind of "lamenting" sound, which they mostly use when approaching a wateringhole, perhaps to warn an existing dingo.
According to the current state of knowledge, it is not possible to make Australian bark bark more frequently by placing them in contact with other domestic dogs. However, German zoologist Alfred Brehm reported dingo studying the more "common" form of barking and how to use it, while his brother did not. Whether dinging or bark skin is less common is generally uncertain.
Howling
Dingo has three basic forms of howling (moaning, leather-howl and tobacco) with at least 10 variations. Usually, three types of howls are distinguished: long and continuous, up and down, and short and abrupt.
Observations have shown that each kind of howling has some variation, although their purpose is unknown. Frequency howling varies with season and time, and is also influenced by breeding, migration, lactation, social stability and dispersal behavior. Howling can be more frequent at the time of lack of food, because dogs become more widely distributed within the reach of their homes.
In addition, howling seems to have a group function, and is sometimes an expression of joy (eg, greeting). Overall howling is observed less frequently in dingo than among the gray wolves. It may happen that one dog will start howling, and some or all of the other dogs will howl and bark from time to time. In the wilderness, dingo sweeps remotely to attract other members of the parcel, to look for other dogs, or to keep the intruders away. Dingo howl in the choir with a significant tone, and as the number of pack members increases, variability of pitches also increases. Therefore, it is suspected that dingo can measure packet size without visual contact. In addition, it has been suggested that a very varied chorus howling can produce a confounding effect in the receiver by making the packet size appear larger.
Other forms of communication
Growing, forming about 65% of vocalizations, is used in an agonistic context for dominance, and as a defensive voice. Similar to many domestic dogs, the reactive use of defensive graft is rarely observed. It develops very often in combination with other sounds, and has been observed almost exclusively in sound swooshing (similar to barking).
During the observation in Germany, the dingo was heard to produce a sound which the observer called Schrappen . It is only observed in an agonistic context, mostly as a defense against prominent puppies or to defend resources. It is described as a bite intent, in which the recipient is never touched or injured. Only a tooth clash can be heard.
In addition to vocal communication, dingo communicates, like all domestic dogs, through the scent that marks certain objects (eg, Spinifex ) or places (such as waters, walkways and hunting places) using chemical signals from their urine, and scent glands. Men mark more often than women, especially during breeding season. They also smell, in which the dog rolls up his neck, shoulders, or back on something normally associated with food or other dogs smell marks.
Unlike wolves, dingo can react to social cues and cues from humans.
Behavior
Dingo tends to be active at night in warmer areas, but less so in colder areas. The main period of their activity is around dusk and dawn. The activity period is short (often less than an hour) with short rest periods. Dingo has two types of movements: a search movement (apparently related to hunting) and exploration movements (perhaps for contact and communication with other dogs). According to research in Queensland, wild dogs (hybrid dingo) there, move freely at night through urban areas and cross streets and seem quite familiar.
Social behavior
The dingo social behavior is roughly as flexible as the coyote or gray wolf, which may be one of the reasons originally believed that dingo came from Indian wolves. While young males are often solitary and nomadic in nature, adult breeding will often form a settling packet. However, in dingo habitat areas with very large populations, breeding couples remain together, apart from others. The Dingo distribution is a single dingo, 73%, two dingo, 16%, three dingo, 5%, four dingo, 3% and five to seven dingo packages, 3%. Dingo packages usually consist of couples who are wed, their offspring from the current year and sometimes offspring from the previous year.
Where favorable conditions are between dingo packages, stable packages with different areas and slightly overlap between neighbors. Package sizes often appear according to the prey size that appears in the pack area. The desert area has smaller dingo groups with looser territorial behavior and shared water spots. It has been noted that the average monthly packet size is between three and twelve members.
Similar to other canids, dingo packets consist mostly of mated couples, their current offspring, and sometimes children years before. There is a hierarchy of dominance both between and within men and women, with men usually more dominant than women. However, some exceptions have been recorded in captive packets. During the trip, while eating prey, or when approaching the water source for the first time, the stud will be seen as a leader, or alpha. Subordinate dogs will approach a more dominant dog with a slightly crouch posture, flat ears and tail down, to ensure peace in the pack. The creation of artificial packages in captive dingoes has failed.
Reproduction
Dingoes breed once every year, depending on the female estrus cycle which, according to most sources, only comes in one summer per year. Female dingo can enter heat twice per year, but can only get pregnant once a year, with a second time just seem pregnant.
Male males throughout the year in most areas, but have lower sperm production during the summer in many cases. During the study of dingo from the Eastern Highlands and Central Australia in captivity, no specific breeding cycle could be observed. Everything is strong all year round. Breeding is only regulated by the heat of the female. Testosterone increases are observed in men during the breeding season, but this is associated with females heat and intercourse. In contrast to captive dingoes, the dingo man who was captured from Central Australia really showed evidence of male breeding cycles. Those dingo show no interest in women in the heat (currently other domestic dogs) outside the breeding season (January to July) and do not breed with them.
The mating season usually occurs in Australia between March and May (according to other sources between April and June). During this time, dingo can actively defend their territory using vocalization, dominant behavior, growling and barking.
Most females in the wild begin to multiply by the age of two. In the package, alpha women tend to become hot before subordinates and actively suppress married attempts by other women. Men become sexually mature between the ages of one and three. The precise beginning of breeding varies depending on age, social status, geographic range and seasonal conditions. Among the dingo in captivity, pre-estrus is observed to last 10-12 days. However, it is suspected that pre-estrus can last for 60 days in the wild.
In general, the only dingo in the pack that successfully breeds is an alpha pair, and other package members help raise their children. Subordinates are actively prevented from breeding by alpha partners and some subordinate women have false pregnancies. Low or solitary dingo can successfully reproduce if the package structure is lost.
The gestation period lasts for 61-69 days and the litter size can range from one to 10 (usually five) pups, with the number of males born tending to be higher than females. Pups of subordinate women are usually killed by alpha women, which causes the population to rise to low even in good times. This behavior may be developed as an adaptation to the turbulent environmental conditions in Australia. Dogs are usually born between May and August (winter period), but in the tropics, breeding can occur at any time of the year.
At the age of three weeks, her children leave the nest for the first time, and leave it completely for eight weeks. In Australia, the nest is mostly underground. There are reports of nests in abandoned rabbit holes, rock formations, beneath the rocks in the dry creek, under a large spinifex, in logs, in enlarged holes of monitor lizards and wombats. The puppies usually get lost around the nest within a 3 km (2 mi) radius, and are accompanied by older dogs during longer trips. The transition to solid foods is usually accompanied by all pack members during the 9 to 12 weeks of age. Apart from their own experience, children also learn through observation. Young dingo usually become independent at the age of three to six months or they spread at the age of 10 months when the next breeding season begins.
Migration
Dingo usually stays in one area and does not undergo seasonal migration. However, during times of famine, even in "safe" areas usually, dingo travels to the grazing areas, where intensive human control measures are carried out. It was noted in Western Australia in the 1970s that young dogs can travel long distances when needed. About 10% of captured dogs - all younger than 12 months - were then recaptured away from their first location. Among these, 10% of the mileage for men is 21.7 km (13.5 mi) and for women 11 km (7 mi). Therefore, dingoes travel has a lower chance of survival in foreign territory, and it seems unlikely that they will survive long migration through the occupied territory. The scarcity of long migration routes seems to confirm this. During the investigation on the Nullarbor Plain, even longer migration routes were recorded. The longest recorded migration route of radio-collared dingo is about 24-32 km (15-20 mi).
Attack on humans
Although dingo is big enough to be dangerous, they usually avoid conflict with humans. Regardless of the well-known case where a baby is taken from a campsite (see below), there are many confirmed dingo attacks, often involving people feeding wild dingo, especially on Fraser Island, a dingo-related tourism-specific center (see main article). Most dingo attacks are small, but some can be large, and some can be fatal. Many Australian national parks have signs that advise visitors not to feed wildlife, partly because this practice is unhealthy for animals, and partly because it can encourage undesirable behavior, such as grabs or bites by dingo, kangaroos, caves and some birds.
Impact
Extinction
Some researchers propose that dingo caused the extinction of thylacine, Tasmanian devil and Tasmanian nativehen from the Australian mainland due to correlation in space and time with the arrival of Dingo. Recent studies have questioned this proposal, suggesting that climate change and an increasing human population may have been the cause. Dingo does not seem to have the same ecological impact as the red fox at a later time. This may be related to the way dingo hunting and the size of their favorite prey, as well as the amount of dingo low in the time before European colonization.
The assumption that the Tasmanian dingo and tiger are competitors for the same prey comes from their external similarities; thylacine has stronger and more efficient bites, but may depend on relatively small prey, while a stronger dingo skull and neck will allow it to carry larger prey. Dingo may be a superior hunter, as it hunts cooperatively in packages and can better defend resources, while the Thylacine may be more aloof. Also, wild dingo populations may have demographic support from life that is incompatible with humans.
The extinction of thylacine in the continent some 2,000 years ago has also been linked to climate change and land use by Aboriginal people. It makes sense to name dingo as the cause of extinction, but significant morphological differences between the two indicate that the ecological overlap of both species may be excessive. Dingo has the teeth of a generalist, while the thylacine has a specialist carnivore teeth with no signs of carcass or bone consumption. It is also said that thylacine is a flexible predator that should survive from competition with dingo, but instead be removed due to human oppression.
This theory does not explain how Tasmanian devils and dingo lived side by side on the same continent until about 430 years ago, when dingo supposedly caused the death of Tasmanian devil. The dynamics of the dingo group should have succeeded in getting the demon away from the carcass, and since the dingo dog is able to break the bone, little will be left for the devil to scavenge. In addition, the Devil is a successful hunter from small to medium-sized prey, so there should be overlapping species in this area as well. Furthermore, the argument that dingo caused the extinction of thylacine, demon and hen in direct conflict with each other. If dingo is really very similar to the Thylacine and Tasmanian devils in its ecological role and suppressing both, then coexisting with them for a long time is strange. Although this is a possible outcome of the introduction of Dingo, critics regard this evidence as not substantial.
By 2017, a genetic study found that the northwestern dingo population has begun to develop from 4,000 to 6,000 years ago. This was proposed because of their first arrival in Australia or because of the extinction of the Tasmanian tiger with dingo evolving into the range of the previous Tasmanian tiger.
Ecological impact
Dingo is considered part of the native fauna of Australia by many environmentalists and biologists, as these dogs existed on the continent before the arrival of Europeans and the mutual adaptation of the dingo and surrounding ecosystems had occurred.
Many of today's wild dog spots in the Australian ecosystem, especially in urban areas, are still unknown. Although the ecological role of dingo in Northern and Central Australia is well understood, the same does not apply to the role of wild dogs in the eastern part of the continent. In contrast to some claims, dingo is assumed to have a positive impact on biodiversity in areas where wild foxes are present.
Dingo is considered a top predator and may perform ecological key functions. Very likely (with increasing evidence from scientific research) that they control the diversity of ecosystems by limiting the number of prey and keeping competition in check. Wild dogs hunt wild animals such as goats and pigs, as well as natural prey and introduced animals. The low number of wild goats in Northern Australia may be due to the presence of dingo, but whether they control the number of goats or not is still debatable. Studies from 1995 in Australia's northern wetlands found that dingo there did not reduce the number of wild pigs, but their predation only affected the pig population along with the presence of buffalo (which hindered the access of pigs to food).
Observations on the mutual effects of dingo and red fox and cat populations show dingoes limiting access to foxes and cats to a particular resource. Consequently, it is assumed that the loss of dingo can lead to an increase in the number of red foxes and stray cats and, therefore, higher pressure on native animals. These studies found the presence of dingo is one factor that keeps the number of foxes in low areas, and therefore reduces the pressure on the native animals, which then does not disappear from the area. The number of red foxes across the country is very high where the amount of dingo is low, but other factors may be responsible for this, depending on the region. Evidence is found for competition between wild dogs and red foxes in the Blue Mountains of New South Wales, as there is considerable overlap in the preferred prey spectrum, but there is only evidence for local competition, not on a large scale.
There is also the possibility that dingo can live with red foxes and wild cats without reducing their numbers in areas with adequate food sources (eg, high rabbit figures) and hiding places. Almost nothing is known about the relationship between wild dogs and stray cats, except that they mostly live in the same area. Although wild dogs also eat cats, it is unknown whether this affects cat populations. Currently, the Invasive Animal Cooperative Research Center is investigating the exact effects of dingo on populations of foxes and cats to determine the benefits of keeping dogs in certain areas of Australia. In many areas, wild dogs live along with most of the quolls species, except the eastern quoll, which may have become extinct on land, so stray dogs are not considered a threat to them.
In addition, the loss of dingo may increase the prevalence of Australian kangaroo, rabbit and brushturkey numbers. In the outer areas of Dingo Fence, the number of dingo and emu is lower than within the area. However, the amount changes depending on the habitat. Because the environment is the same on both sides of the fence, dingo is assumed to be a powerful factor for the regulation of this species. Therefore, some people demand that dingo numbers be allowed to be upgraded or dingo should be reintroduced in areas with low dingo populations to reduce pressure on endangered native species populations and to reintroduce them in certain areas. In addition, the presence of Australian brushturkey in Queensland increased significantly after the dingo bait was made.
Cultural impact
Cultural opinions about dingo are often based on the assumption of "cunning", and the idea that it is a transition between civilization and wildness.
Some early European settlers viewed dingo as a domestic dog, while others thought they were more like wolves. For years, the dingo began to attack the sheep, and their relationship with the Europeans changed very quickly: they were considered cunning and cowardly, because they did not fight fiercely in the eyes of Europeans, and disappeared into the bushes. Dingo is seen as a killing predator with a mischievous, not because of hunger (similar claims made today about dingo-hybrids). In addition, they are seen as promiscuous or as devils with venomous bites or saliva, and so they can be killed unconditionally. For years, the dingo trappers have gained prestige for their work, especially when they manage to kill hard to catch dingo. Dingo is associated with thieves, homeless, bushranger and parliamentary opponents. From the 1960s, politicians began calling their opponents "dingo," meaning they were cowards and traitors, and it has been a popular form of attack ever since. Currently, the word "dingo" still stands for "coward" and "cheat", with verbs and adjectives used as well.
The image of dingo has ranged among several groups from instructive to demon.
The ceremony (as it is sharp on the Cape York Peninsula in the form of howling) and dream stories connected to the dingo, passed down from generation to generation.
Dingo plays an important role in the dreamtime stories of native Australians, but dingo is rarely depicted in their cave paintings when compared to extinct thylacines. One of the Yarralin tribal elders, the Northern Territory states that dingo dreamtime is the ancestor of dingo and humans. Dingo "is what we would do if we were not like us."
Similar to how Europeans buy dingo, Aboriginal people in Australia get dogs from immigrants very quickly. The process was so rapid that Francis Barrallier (surveyor at the beginning of the expedition around the colony in Port Jackson) discovered in 1802 that five European dogs were there before him. One theory suggests that other domestic dogs will adopt the role of "pure" dingo. Introduced animals, such as water buffalo and domestic cats, have been adopted into the original Aboriginal culture in the form of rituals, traditional paintings and dream stories.
Most of the published myths come from the Western Desert and show remarkable complexity. In some stories, dingoes are central characters, while in others, they are only small ones. Once upon a time, it was the ancestor of the dream that created man and dingo or gave them its present form. There are stories of creation, socially acceptable behavior, and explanations of why things are as they are. There are myths about modifiers (humans being dingo or otherwise), "dingo-people," and the creation of landscapes or certain elements of the landscape, such as water or mountain holes.
Economic impact
Livestock began to flourish throughout Australia from the early 1800s, leading to a conflict between dingo and sheep breeders. Sheep, and at lower levels of livestock, are easy targets for dingo. Pastoralists and government agencies supporting the industry have shot, trapped, and poisoned dingo or destroyed dingo pups in their nests. After two centuries of persecution, dingo or dingo-dog hybrids can still be found on most continents.
Research on the extent of the damage and the reason for this problem has only just begun recently. Livestock can die from many causes and, when the carcass is found, it is often difficult to determine with certainty the cause of death. Since the results of attacks on livestock depend heavily on the behavior and experience of predators and prey, only a definite direct observation to determine whether the attack was carried out by a dingo dog or other domestic dog. Even the presence of the remains of prey in a wild dog's nest does not prove they are a pest, because wild dogs also eat carcasses. The exact amount or reliable estimate of damage caused by stray dogs, therefore, is difficult to obtain and rarely reliable. Even if livestock is not a large part of the dingo diet, the level of dingo damage can potentially lead to livestock industry could be much larger due to rogue killings.
The significance of dingo as a pest is based primarily on sheep predation and, to a lesser extent, to livestock, and not linked only to the direct loss of livestock. Sheep abuse can lead to less optimal use of pastures and miscarriages.
The livestock industry can tolerate low to moderate, and sometimes high, levels of stray dogs (hence dingo is not so easily considered a pest in these areas). In the case of sheep and goats, zero tolerance is common. The biggest threat is a dog that lives in or near the paddock area. The rate of loss of sheep is difficult to determine, because of the vast grassland lands in parts of Australia. The number of livestock losses is much more variable and poorly documented. Although the loss of livestock may increase by 30%, the normal loss rate is about 0-10%.
Therefore, factors such as the availability of native prey, as well as defending behavior and livestock health, play an important role in the amount of loss. A study in Central Australia in 2003 confirmed that dingo has only a low impact on livestock numbers when adequate supply of other prey (such as kangaroos and rabbits) is available. In some parts of Australia, it is assumed that the loss of calves can be minimized if horned animals are used instead of polling. The exact economic impact is unknown in this case, and it is unlikely that the rescue of several calves compensates for the costs required for control measures. The calves usually suffer wounds that are lighter than sheep because of their size and protection by adult cattle, and therefore have a higher chance of surviving the attack. As a result, evidence of dog attacks can only be found after livestock is herded back to the cage, and signs such as ear bites, tails and other wounds are found.
The owner's opinion about dingo dogs is more varied than sheep owners. Some livestock owners believe that it is better for a weak mother to lose her calf in the dry season so she does not have to take care of her calves as well. Therefore, the owner is more hesitant to kill the dingo dog. The livestock industry can benefit from dingo predation on rabbits, kangaroos and mice. Furthermore, the mortality rate of calves has many possible causes, and it is difficult to distinguish them. The only reliable method for documenting the damage is to document all pregnant cows, then observe their development and their calves. The loss of calves in the area observed where dingo is controlled is higher than in other areas. The loss of livestock, therefore, is not always caused by the occurrence of dingo and is not dependent on wild dogs. A researcher has stated that for cattle stations where dingo is controlled, kangaroos are abundant, and this affects the availability of grass.
Domestic dogs are the only large Australian ground predator to kill perfectly grown sheep, and only a few sheep have recovered from severe injuries. In the case of sheep, death can have many causes other than attacks by predators, who are blamed for deaths because they eat from carrion. Although red fox attacks are possible, such attacks are less frequent than previously thought. The fact that the sheep and goat industries are much more vulnerable to damage caused by stray dogs than the livestock industry is largely due to two factors: the behavior of sheep flight and their tendency to flock together in the face of danger, and the hunting of wild dog methods, along with the way they handle efficient goats and sheep.
Therefore, damage to the livestock industry is not correlated with the number of wild dogs in an area (except that there is no damage where no stray dogs occur).
