Darwin's Fox or Darwin's Zorro (Pseudalopex fulvipes) is a small endangered canine from the genus Pseudalopex, also know as Chiloé Zorro or Zorro Chilote in Spanish (zorros is false fox, more related to true dogs and included to Canini tribe) and live in Chiloé Island and then Nahuelbuta National Park in mainland of Chile (IX Region Araucania).

Darwin's Fox was first collected from Chiloé Island off the coast of Chile by the naturalist Charles Darwin in 1834. It was long held that Darwin's Fox was a subspecies of the Grey zorro (P. griseus); however, the discovery of a small population of Darwin's Fox on the mainland in Nahuelbuta National Park in 1990^[2] and subsequent genetic analysis has clarified the fox's status as a unique species.^[3].

Taxonomy and evolution

Pseudaloplex is a South American genus of canine distantly related to wolves and is technically not a fox. When Charles Darwin collected a specimen from Chiloé Island, he observed that it was distinct from the species, P. culpaeus and P. griseus, that occur on the mainland^[4]. Darwin's Fox does not interbreed with the other Pseudalopex species, only lives in forests, and is smaller and darker-colored than the other species. It was not until a small population of Darwin's Fox was found on the mainland in the forested Nahuelbuta National Park and subsequent genetic analysis was performed, that the Darwin's Fox was confirmed as a distinct species.

Historic of classification

Darwin's fox firstly was described by Charles Darwin during his travel on Beagle ship. Later, population of Darwin's Fox live in Chiloé was distinguish as subspecies Grey Fox (Pseudalopex griseus fulvipes). When in 1990, scientists discovered new population exists in Nahuelbuta National Park begin discussion for new taxonomy of "Chiloé" fox, not endemic to this island but live also in continent. In according to Yanke et al., in their 1996 article publish in Conservation Biology, show mitochondrial analysis compared of two patterns (Darwin's Fox and Grey Fox) confirm vary elements component of nucleosomes and recognized rare specimens as new species, even more related to Sechura Fox. In according to Yahnke (1995; et al.1996 ) they are relict of a former more widely range. Now Darwin's Fox have classified as distinct, but sympatric species, was results working of divergency selection and describe as sisterly taxon. Zoologist noticed totally other ecological niche, appearance and behavior. Darwin's Fox is various from Grey Fox and darker, has shorter legs, a broader, shorter skull, smaller auditory bullae, a more robust dentition and also differs from the Grey Zorro in jaw shape and its style of premolar occlusion.

In the late Pleistocene, Chiloé Island was connected to mainland Chile by a land bridge. The land bridge was severed about 15,000 years ago when the sea level rose following the last glaciation^[5]. This created two isolated populations of Darwin's Fox. This article is about the Male sex. ...

Physical description

Darwin's fox has a dark brown coat with red areas on its head and face, and it has shorter legs than the mainland foxes, and weighs 2-4 kg, much smaller than the P. griseus which weighs between 5-10 kg^[3]. Coat of Darwin's Fox is dark grey-violet with red areas on it ears, head and limbs. Their dewlap and underbelly is mainly white, and thorax is sometimes locally cover of white coating. Darkness is the absence of light. ... For an alternative meaning, see ear (botany). ...

Diet

Darwin's Fox feed on various food. In thick forests, where it exists, foxes hunt for mammals, reptiles, beetles and other invertebrates. Sometimes selects fruits and berries.

Ecology

Darwin's fox is generally believed to be a forest obligate species found only in southern temperate rainforests^[6]. They only occur in forested areas on Chiloé and on the mainland. They are most active at twilight and before sunrise. Darwin's fox is generally only occur in the southern primary temperate subtropical forests their range - variously from other false foxes (especially Pseudalopex), prefers open spaces. They only exist in forested areas on Chiloé and on the mainland and are most active at twilight and before sunrise. The population of Chiloé calculate about 200 individuals, Nahuelbuta in nearly 50 individuals. Total population size is less than 250 mature individuals with at least 90% of the population occurring in one subspopulation (Chiloé Island). Although the species is protected in Nahuelbuta National Park, substantial mortality sources exist when foxes move to lower, unprotected private areas in search of milder conditions during the winter. ( Jiménez, J.E., Lucherini, M. & Novaro, A.J., 2004; IUCN & CSG 2004). On mainland Chile, Jaime Jiménez has observed a small population since 1975 in Nahuelbuta National Park; this population was first reported to science in the early 1990s (Medel et al. 1990; Jiménez, J.E., Lucherini, M. & Novaro, A.J., 2004; IUCN, 2004). A rainforest is a forested biome with high annual rainfall. ... For other uses, see Twilight (disambiguation). ...

Conservation status

It is believed that there are only 250 Darwin's foxes on Chiloé Island and up to 70 on the mainland, and they are listed as critically endangered by the World Conservation Union^[6]. Fragmentation of forest adjacent to National Parks is a concern for their conservation and dogs in the Parks may be the greatest conservation threat in the form of potential vectors of disease or direct attack. The World Conservation Union or International Union for the Conservation of Nature and Natural Resources (IUCN) is an international organization dedicated to natural resource conservation. ...

Threats for populations of Darwin's Fox is devastation unique forest - their habitat, diseases from feral dogs and direct persecution by people, think that foxes attack the fowls.
