Is the golden jackal an endangered species?
1554274#33
The golden jackal is listed as Least Concern on the IUCN Red List due to its widespread distribution, with it being common throughout its range and with high densities in those areas where food and shelter are abundant. In Europe, golden jackals are not listed under the 1973 "Convention on International Trade in Endangered Species of Wild Fauna and Flora" nor the 1979 Convention on the Conservation of Migratory Species of Wild Animals. Golden jackals in Europe fall under various international legal instruments. These include the 1979 "Berne Convention on the Conservation of European Wildlife and Natural Habitats", the "1992 Convention on Biological Diversity", and the 1992 European Union "Council Directive 92/43/EEC on the Conservation of Natural Habitats and of Wild Fauna and Flora". The Council Directive provides both guidance and limits on what participating governments can do when responding to the arrival of expanding jackals. These legislative instruments aim to contribute to conserving native wildlife; some governments argue that the golden jackal is not native wildlife but an invading species. The Golden Jackal informal study Group in Europe (GOJAGE) is an organization that is formed by researchers from across Europe to collect and share information on the golden jackal in Europe. The group also has an interest in the golden jackal's relationship with its environment across Eurasia. Membership is open to anyone who has an interest in golden jackals.

Results from two recent studies of mDNA from golden jackals indicate that the specimens from Africa are genetically closer to the gray wolf than are the specimens from Eurasia. In 2015 a major DNA study of golden jackals concluded that the six "C.aureus" subspecies found in Africa should be reclassified under the new species "C.anthus" (African golden wolf), reducing the number of golden jackal subspecies to seven. The phylogenetic tree generated from this study shows the golden jackal diverging from the wolf/coyote lineage 1.9million years ago and the African golden wolf diverging 1.3million years ago. The study found that the golden jackal and the African golden wolf shared a very similar skull and body morphology and that this had confused taxonomists into regarding these as one species. The study proposes that the very similar skull and body morphology is due to both species having originated from a larger common ancestor.

The Arno river dog ("Canis arnensis") is an extinct species of canine that was endemic to Mediterranean Europe during the Early Pleistocene around 1.9million years ago. It is described as a small jackal-like dog and probably the ancestor of modern jackals. Its anatomy and morphology relate it more to the modern golden jackal than to the two African jackal species, the black-backed jackal and the side-striped jackal.

Some golden jackals carry diseases and parasites harmful to human health. These include rabies, and Donovan's "Leishmania" that is harmless to jackals but may cause leishmaniasis in people. Jackals in southwestern Tajikistan can carry up to 16 species of parasitic cestodes (flatworm), roundworms, and acanthocephalans (thorny-headed worms), these are: "Sparganum mansoni", "Diphyllobothrium mansonoides", "Taenia hydatigena", "T.pisiformis", "T.ovis", "Hydatigera taeniaeformis", "Dipylidium caninum", "Mesocestoides lineatus", "Ancylostoma caninum", "Uncinaria stenocephala", "Dioctophyma renale", "Toxocara canis", "Toxascaris leonina", "Dracunculus medinensis", "Filariata" and "Macracanthorhynchus catulinum". Jackals infected with "Dracunculus medinensis" can infect bodies of water with their eggs, which cause dracunculiasis in people who drink from them. Jackals may also play a large part in spreading coenurosis in sheep and cattle, and canine distemper in dogs. In Tajikistan, jackals may carry up to 12 tick species (which include "Ixodes", "Rhipicephalus turanicus", "R.leporis", "R.rossicus", "R. sanguineus", "R.pumilio", "R.schulzei", "Hyalomma anatolicum", "H.scupense" and "H.asiaticum"), four flea species ("Pulex irritans", "Xenopsylla nesokiae", "Ctenocephanlides canis" and "C.felis"), and one species of louse ("Trichodectes canis").

The oldest golden jackal fossil was found at the Ksar Akil rock shelter located northeast of Beirut, Lebanon. The fragment of a single tooth is dated approximately 7,600 years ago. The oldest golden jackal fossils found in Europe are from Delphi and Kitsos in Greece and are dated 7,000–6,500 years ago. An unusual fossil of a heel bone found in Azykh Cave, in Nagorno-Karabakh, dates to the Middle Pleistocene and is described as probably belonging to the golden jackal, but its classification is not clear. The fossil is described as being slightly smaller and thinner than the cave lynx, similar to the fox, but too large, and similar to the wolf, but too small. As the golden jackal falls between these two in size, the fossil possibly belongs to a golden jackal. The absence of clearly identified golden jackal fossils in the Caucasus region and Transcaucasia, areas where the species currently resides, indicates that the species is a relatively recent arrival.

Golden jackals are abundant in valleys and beside rivers and their tributaries, canals, lakes, and seashores. They are rare in foothills and low mountains. The golden jackal is a social species, the basic social unit of which consists of a breeding pair and any young offspring. It is very adaptable, with the ability to exploit food ranging from fruit and insects to small ungulates. They will attack domestic fowl and domestic mammals up to the size of domestic water buffalo calves. The jackal's competitors are the red fox, wolf, jungle cat, forest wildcat, and, in the Caucasus, the raccoon, and, in Central Asia, the steppe wildcat. The jackal is expanding beyond its native grounds in Southeast Europe into Central Europe, occupying areas where there are few or no wolves.

Jackal populations have been increasing in Serbia since the late 1970s, and occur mainly in north-eastern Serbia and lower Srem. Jackals are especially common near Negotin and Bela Palanka (close to the border with Bulgaria), where during the 1990s, about 500 specimens were shot. In Croatia, a 2007 survey reported 19 jackal packs in the north-western part of Ravni kotari and two on Vir Island. Golden jackals are listed as a protected species in Slovenia, where they were first spotted in 1952 and have also established permanent territories there. In 2005, a probably vagrant female was accidentally shot near Gornji Grad in the Upper Savinja Valley, Northern Slovenia. In 2009, two territorial groups of golden jackal were recorded in the Ljubljana Marshes area, Central Slovenia. It seems that the species continues to expand towards Central Europe. Jackal populations in Albania however are on the verge of extinction with possible occurrence in only three lowland wetland locations along the Adriatic Sea.

In Iran, some golden jackals carry intestinal worms (helminths) and "Echinococcus granulosus". In Israel, some jackals are infected with intestinal helminths and "Leishmania tropica". In Romania, a jackal was found to be carrying "Trichinella britovi". In northeastern Italy, the jackal is a carrier of the tick species "Ixodes ricinus" and "Dermacentor reticulatus", and the smallest human fluke "Metagonimus yokogawai" that can be caught from ingesting infected raw fish. In Hungary, some jackals carry dog heartworm "Dirofilaria immitis", and some have provided the first record in Hungary of "Trichinella spiralis" and the first record in Europe of "Echinococcus multilocularis". The jackal is dispersing across Europe through rivers and valleys, bringing parasites into regions where these did not previously exist.

The golden jackal can be a harmful pest that attacks domestic animals such as turkeys, lambs, sheep, goats, domestic water buffalo calves, and valuable game species like newborn roe deer, hares, coypu, pheasants, francolins, grey partridges, bustards and waterfowl. It destroys grape, coffee, maize, sugarcane, and eats watermelons, muskmelons, and nuts. In Greece, golden jackals are not as damaging to livestock as wolves and red foxes but they can become a serious nuisance to small stock when in great numbers. In southern Bulgaria, over 1,000 attacks on sheep and lambs were recorded between 1982 and 1987, along with some damage to newborn deer in game farms. The damage by jackals in Bulgaria was minimal when compared to the livestock losses due to wolves. Approximately 1.5–1.9% of calves born in the Golan Heights die due to predation, mainly by jackals. The high predation rate by jackals in both Bulgaria and Israel is attributable to the lack of preventative measures in those countries and the availability of food in illegal garbage dumps, leading to jackal population explosions.

The biological family "Canidae" is composed of the South American canids, the fox-like canids, and the wolf-like canids. All species within the wolf-like canids share a similar morphology and possess 78chromosomes, allowing them potentially to interbreed. Within the wolf-like canids is the jackal group, which includes the three jackals: the black-backed jackal ("C.mesomelas"), the side-striped jackal ("Canis adustus"), and the golden jackal ("Canis aureus"). These three species are approximately the same size, possess similar dental and skeletal morphology, and are identified from each other primarily by their coat color. They were once thought to have different distributions across Africa with their ranges overlapping in East Africa (Ethiopia, Kenya, and Tanzania). Although the jackal group has traditionally been considered as homogenous, genetic studies show that jackals are not monophyletic (they do not share a common ancestor), and they are only distantly related. The accuracy of the colloquial name "jackal" to describe all jackals is therefore questionable.
