Lycalopex gymnocercus (Fischer, ) is a canid commonly called the Pampas fox. A sexually dimorphic fox-like carnivore of medium size. Abstract. The seasonal diet of Pampas foxes (Lycalopex gymnocercus) was examined from scat samples collected during 1 year in the dry Chaco woodland.

Lycalopex gymnocercuspampas foxes, are gymnocercuus in Paraguay, Uruguay, southern Brazil, eastern Bolivia and north of Rio Negro in Argentina. Wilson and Reeder, These foxes are found in the pampas grasslands, hills, heath, ridges and deserts. Gymmocercus prefer plains and fields with tall grass, sierras, and small narrow wood areas along streams and occasionally forest areas.
Lycalopex gymnocercus is a medium-sized fox which has a brindled grey back with paler grey underparts. The head, neck and large ears are reddish, as are the outsides of the legs.
The muzzle is black as far as the corners of the mouth, a feature that distinguishes them from the similar culpeo fox Lycalopex culpaeus. Like other species in the genus, the long, bushy tail of L. These animals weigh between 4. The tail length for Pampas Foxes averages about 34 cm. Those animals in the northern part of their range are more vividly colored. This species is monogamous. It is not known whether these foxes retain the same mate in subsequent breeding seasons, as they are solitary outside of the breeding season.
Pampas foxes are usually solitary, but are seen in pairs during the mating season. Breeding is monogamous and occurs from July through October.
Both parents care for the young. Gestation lasts from days. Females bear three to five pups in a den among rocks, under bases of trees or in burrows made by other animals. Young are born almost black but gradually lighten as they grow. At two to three months, the young begin to hunt with their parents. Age at maturity is unknown. The male pampas fox brings food to the female and her pups, who stay within the den until the pups are about three months old.
At this time, the pups begin to hunt with their parents. Females nurse the pups in the den. The male will provide food for the altricial pups and females at the den.
Young stay at the den for the first three months, after which they hunt with parents. Pampas foxes live about Ltcalopex foxes have a relatively solitary lifestyle, except during the breeding season and when caring for their young.
They exhibit two particularly interesting behaviors. They are known fymnocercus collect objects which apprear mostly useless to them, such as bits of cloth and leather, which are often found in their dens. They also appear to play dead when approached by humans. If they are startled, these foxes will throw themselves to the ground, rigid, with their eyes closed, and remain in this position gymhocercus the perceived threat passes.
Although primarily nocturnal, they may be active during day in areas with low human populations. Lycalopex gymnocercus is omnivorous, but primarily eats meat. These foxes are known to eat frogs and lizards. Fruits and other vegetable matter, like sugar cane stalks, are sometimes consumed.
Near human dwellings they are said to take domestic poultry. Information on predation is not available. Humans frequently hunt these foxes, thinking that they destroy livestock.

The pampas fox may fall prey to eagles or larger carnivores. Lycalopex gymnocercus individuals remain motionless gymncercus humans make an appearance, and may continue to remain motionless if physically molested. This may be an antipredator behavior in which the fox tries to avoid being eaten by pretending not to be there at all.
Grambo, ; Nowak, The decline in L. It can reasonably be inferred from this that fox predation plays an important role in regulating the populations of prey animals. These foxes are hunted and trapped for fur in several countries, including Uruguay, Paraguay, and Argentina.
They are captured most often with leg-hold traps, but also caught using bowls, box traps, and dogs. Because lhcalopex foxes keep agricultural pest populations in check, they have a positive impact on agriculture. Grambo, ; Grambo, Sometimes these foxes kill young sheep or take domestic poultry.
In Brazil, where the gymnoercus enjoys complete protection, there is no market for fur. Pampas foxes are protected in Paraguay and Uruguay, but controlled hunting continues in these two countries. These foxes were previously recognized in the genera Pseudalopex and Dusicyon. In birds, naked and helpless after hatching.
Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria. Vegetation is typically sparse, though spectacular blooms may occur following rain. Deserts can be cold or warm and daily temperates typically fluctuate. In dune areas vegetation is also sparse and conditions are dry. This is because sand does not hold water well so little is available to plants.
In dunes near seas and oceans this is compounded by lycalipex influence of salt in the air and soil. Salt limits the ability of plants to take up water through their roots.
Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a now extinct synapsid ancestor; the fossil record does not distinguish these possibilities.
Iteroparous animals must, by definition, survive over multiple seasons or periodic condition changes.
