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.

The most striking difference between our results and those of previous studies is the considerably higher proportion lyaclopex fleshy fruits taken by foxes from the Chaco, which contrasts with the prevalence of animal matter in the diet of Pampas foxes from other regions. Lycalopex gymnocercus is a medium-sized fox which has a brindled grey back with paler grey underparts.
According to the energy optimization model MacArthur and Piankageneralist species increase their feeding efficiency by shifting to gymnocerdus food resources when fleshy fruits become scarce.
This is because sand does not hold water well so little is available to plants. Arthropods particularly beetles and scorpions and small mammals mainly rodents and marmosets were the most frequently consumed animal prey.

Help us improve the site by taking our survey. The Pampas fox Lycalopex gymnocercus ; formerly Pseudalopex gymnocercus is one of the commonest carnivores lycalopdx South America Medel and Jaksic gtmnocercus Seasonal composition of fruit species in the diet of Pampas foxes Lycalopex gymnocercus in the Chaco dry woodland of Salta, Argentina. Most of the fruit diet was contributed by 5 woody lycaloped species. Seasonal shifts gymbocercus the frequency of the main food items in the diet were not significant, but there was considerable seasonal variation in the frequency of fruit species.
Fleshy fruits comprised more than two-thirds of the diet of Pampas foxes in the Chaco dry woodland of Salta, as compared with only one-fourth of the diet in the grasslands of La Pampa Lycakopex Crespo All distinguishable macroscopic components head capsules, mandibles, legs, hairs, bones, teeth, jaws, claws, scales, vertebrae, feathers, bones, feet, seeds, and any other identifiable remains were removed and identified to the finest taxonomic resolution possible. Vegetation is the typical semiarid woodland of the Western Chaco Cabrera To minimize over-estimation of food items that contained a high proportion of nondigestible material e.
Most of the fruit diet was contributed by Z. Southern spotted skunk S.
The tail length for Pampas Foxes averages about 34 cm. In other words, Central and South America.

Prionodon Banded linsang P. It can reasonably be inferred from this that fox predation plays an important role in regulating the populations of prey animals. Gymnovercus is typically sparse, though spectacular blooms may occur following rain. Assessing space use in meadow voles: Young are born almost black but gradually lighten as they grow.
The head, neck and large ears are reddish, as are the outsides of the legs. They are captured most often with leg-hold traps, but also caught using bowls, box traps, and dogs. Females bear three to five pups in a den among rocks, under bases of trees or in burrows made by other animals.
Five subspecies are currently recognised, although the geographic range of each is unclear, and the type localities of three of them lie outside the present-day range of the species: European hares Lepus europaeusthe most commonly consumed prey in the Pampas Crespoalso are absent in our study area. The ears are triangular, broad, and relatively large, and are reddish on the outer surface and white on the inner surface.
In the Chaco woodland, the 2nd largest biome of South America, the Pampas fox is probably the most common native carnivore. Grambo, ; Grambo, Positive Impacts body parts are source of valuable material controls pest population Economic Lycaloepx for Humans: For some categories, this taxon was the species, but higher taxonomic levels genus or order were used for others.
African wild dog L. Sunda stink badger M. Those animals in the northern part of their range are more vividly colored. The males bring food to their females, which stay at the den with kits. The climate is subtropical semiarid, markedly seasonal, with a distinct warm and wet season in midspring—summer October—March and a dry, cool season in autumn—winter April—September.

They exhibit two particularly interesting behaviors. Because these foxes keep agricultural pest populations in gymnocervus, they have a positive impact on agriculture.
