Jackals
Jackals are canids native to Africa and Eurasia. While the word has historically been used for many canines of the subtribe canina, in modern use it most commonly refers to three species: the closely related black-backed jackal (''Lupulella mesomelas'') and side-striped jackal (''Lupulella adusta'') of Central and Southern Africa, and the golden jackal (''Canis aureus'') of south-central Europe and Asia. The African golden wolf (''Canis lupaster'') was also formerly considered a jackal. While they do not form a monophyletic clade, all jackals are opportunistic omnivores, predators of small to medium-sized animals and proficient scavengers. Their long legs and curved canine teeth are adapted for hunting small mammals, birds, and reptiles, and their large feet and fused leg bones give them a physique well-suited for long-distance running, capable of maintaining speeds of for extended periods of time. Jackals are crepuscular, most active at dawn and dusk. Their most common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Jackal
The golden jackal (''Canis aureus''), also called the common jackal, is a wolf-like canid that is native to Eurasia. The golden jackal's coat varies in color from a pale creamy yellow in summer to a dark tawny beige in winter. It is smaller and has shorter legs, a shorter tail, a more elongated torso, a less-prominent forehead, and a narrower and more pointed muzzle than the Arabian wolf. It is listed as Least Concern on the IUCN Red List due to its widespread distribution and high density in areas with plenty of available food and optimum shelter. Despite its name, the golden jackal is not closely related to the African black-backed jackal or side-striped jackal, which are part of the genus '' Lupulella''. It is instead closer to wolves and coyotes. The ancestor of the golden jackal is believed to be the extinct Arno river dog that lived in southern Europe . It is described as having been a small, jackal-like canine. Genetic studies indicate that the golden jackal expande ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Wolf
The African wolf (''Canis lupaster'') is a Caninae, canine native to North Africa, West Africa, the Sahel, northern East Africa, and the Horn of Africa. It is listed as least concern on the IUCN Red List. In the Middle Atlas in Morocco, it was sighted in elevations as high as . Moliner, V. U., Ramírez, C., Gallardo, M. & Idrissi, H. R. (2012), "Detectan el lobo en Marruecos gracias al uso del foto-trampeo", ''Quercus'', 319:14–15, ISSN 0212-0054 It is primarily a predator of invertebrates and mammals as large as gazelle fawns, though larger animals are sometimes taken. Its diet also includes animal carcasses, human refuse, and fruit. They are monogamous and territorial; offspring remain with the parents to assist in raising their parents' younger pups. The African wolf was previously classified as an African variant of the golden jackal, though a series of analyses on the species' mitochondrial DNA and Nuclear DNA, nuclear genome in 2015 demonstrated that it is a distinct spec ...

Lupulella Mesomelas
The black-backed jackal (''Lupulella mesomelas'') is a medium-sized Caninae, canine native to East Africa, eastern and southern Africa. These regions are separated by roughly . One region includes the southernmost tip of the continent, including South Africa, Namibia, Botswana and Zimbabwe. The other area is along the eastern coastline, including Kenya, Somalia, Djibouti, Eritrea, and Ethiopia. It is listed on the IUCN Red List as least concern due to its widespread range and adaptability, although it is still persecuted as a livestock predator and rabies Vector (epidemiology), vector. Compared to members of the genus ''Canis'', the black-backed jackal is a very ancient species, and has changed little since the Pleistocene, being the most Basal (phylogenetics), basal wolf-like canine. It has a reddish brown to tan coat and a black saddle that extends from the shoulders to the base of the tail. It is a Monogamy in animals, monogamous animal, whose young may remain with the family ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canina (subtribe)
Canina is a taxon which represents the wolf-like Subtribe (biology), subtribe of the Tribe (biology), tribe Canini (tribe), Canini, and is sister to the subtribe Cerdocyonina. Fossil, Fossils of this group date to 5 million years ago; however, they are likely to have been in existence 9 million years ago. Its members as a group are colloquially known as the wolf-like canids. Taxonomy Members of the subtribe Canina are able to produce canid hybrids due to their shared karyotype of 78 chromosomes arranged in 39 pairs. The cladogram below is based on the phylogeny of Lindblad-Toh ''et al''. (2005), modified to incorporate recent findings on ''Canis'' species.

Side-striped Jackal
The side-striped jackal (''Lupulella adusta'' or ''Schaeffia adusta'') is a canine native to Central and Southern Africa. Unlike the smaller and related black-backed jackal (''Lupulella mesomelas''), which dwells in open plains, the side-striped jackal primarily dwells in woodland and scrub areas. Taxonomy and evolution The Swedish zoologist Carl Jakob Sundevall named the species ''Canis adustus'' in 1847. The German zoologist Max Hilzheimer proposed a different genus as ''Schaeffia adusta'' in 1906. Fossil remains of the side-striped jackal date to the Pliocene era. A mitochondrial DNA sequence alignment for the wolf-like canids gave a phylogenetic tree with the side-striped jackal and the black-backed jackal being the most basal members of this clade, which means that this tree is indicating an African origin for the clade. In 2019, a workshop hosted by the IUCN/SSC Canid Specialist Group recommends that because DNA evidence shows the side-striped jackal (''Canis adust ...

Canidae
Canidae (; from Latin, ''canis'', "dog") is a family (biology), biological family of caniform carnivorans, constituting a clade. A member of this family is also called a canid (). The family includes three subfamily, subfamilies: the Caninae, and the extinct Borophaginae and Hesperocyoninae. The Caninae are known as canines, and include Dog, domestic dogs, Wolf, wolves, coyotes, raccoon dogs, Fox, foxes, jackals and other species. Canids are found on all continents except Antarctica, having arrived independently or accompanied by Human, human beings over extended periods of time. Canids vary in size from the gray wolf to the fennec fox. The body forms of canids are similar, typically having long muzzles, upright ears, teeth adapted for cracking bones and slicing flesh, long legs, and bushy tails. They are mostly social animals, living together in family units or small groups and behaving co-operatively. Typically, only the dominant pair in a group breeds and a litter of young ...

Territory (animal)
In ethology, territory is the sociographical area that an animal consistently defends against conspecificity, conspecific competition (biology), competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression. Animals that actively defend territories in this way are referred to as being territorial or displaying territorialism. Territoriality is only shown by a minority of species. More commonly, an individual or a group of animals occupies an area that it habitually uses but does not necessarily defend; this is called its home range. The home ranges of different groups of animals often overlap, and in these overlap areas the groups tend to avoid each other rather than seeking to confront and expel each other. Within the home range there may be a ''core area'' that no other individual group uses, but, again, this is as a result of avoidance. Function The ultimate function of animals inhabiting and defendin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urine
Urine is a liquid by-product of metabolism in humans and many other animals. In placental mammals, urine flows from the Kidney (vertebrates), kidneys through the ureters to the urinary bladder and exits the urethra through the penile meatus (males) or urethral meatus of the vulva (females) during urination. In other vertebrates, urine is excreted through the cloaca. Urine contains water-soluble by-products of Cell (biology), cellular metabolism that are rich in nitrogen and must be clearance (medicine), cleared from the Circulatory system, bloodstream, such as urea, uric acid and creatinine. A urinalysis can detect nitrogenous wastes of the mammalian body. Urine plays an important role in the earth's nitrogen cycle. In balanced ecosystems, urine fertilizes the soil and thus helps plants to grow. Therefore, Reuse of excreta, urine can be used as a fertilizer. Some animals use it to territory (animal)#Scent marking, mark their territories. Historically, aged or fermented urine (kn ...
