Geographic cranial size and shape variation. Glade, G. Canis azarae, m. A previous traditional morphometric study using cranio-dental measurements considered both forms to be the same species, showing clinal reduction in size from northeastern lihnaean southwestern Argentina.

Mauro Lucherini, Estela M. Lycalopex gymnocercus Fischer, is a canid commonly called the Pampas fox. A linnxean dimorphic fox-like carnivore of medium size with reddish coloration on sides and white on the ventral surface, it is 1 of 6 species in the genus Lycalopex. It occurs in eastern Bolivia, western and central Paraguay, Uruguay, north and central Argentina, and southeastern Brazil. It prefers open habitats but also occurs in areas of Pampas grassland modified by extensive ranching and agriculture activities.

N omenclatural N otes. The taxonomic status of the Pampas fox and other related species is controversial. Canids of this genus were alternatively included in the genus Canis LangguthDusicyon Langguthand Pseudalopex Thomas Initially, Pseudalopex was used as a subgenus Kraglievich ; Langguththen later Langguth and Van Gelder placed Pseudalopex as linjaean subgenus of Canisexcluding Dusicyon australis.

Clutton-Brock et al. However, Berta gave full generic recognition to Pseudalopexarguing that the species within this genus culpaeus, griseus, gymnocercus, sechuraeand vetulus share derived features that indicate a what are the four main biological theories of aging origin, separated from other extinct genera that are more closely related to D.

More recently, Zunino et al. They considered Lycalopex as the valid genus name because it was used previously by Burmeister Chromosome analyses by Gallardo and Formas and Vitullo and Zuleta supported this assignment. The most recent revisions of canid phylogeny Bininda-Emonds et al. Only 3 subspecies were recognized by Massoiawho suggested that along the borders of their respective distribution classifucation they would interbreed.

Front feet have 5 toes, 4 with full claws and 1 with a wwhat claw; hind feet have 4 toes Linnaexn and Eisenberg Tracks can be confused with those of other fox-like canids that have 4 toes with short claws in both front and hind feet, because the digit with the dewclaw does not form a visible track. Toe marks are well-separated ovals.

Gestation lasts 55—60 days. Mean number of embryos per female is 3. Young are born in spring, from September—October to December. What does the blue sign mean on bumble lasts about 2 months, and females can breed by 8—12 months Crespo ; Redford and Eisenberg Lycalopex gymnocercus is considered either abundant or common in most areas Lucherini et al.

Reported densities of Pampas foxes were: 1. In the Paraguayan Chaco, abundance may be correlated with annual rodent abundance Brooks In Buenos Aires Province, Argentina, a population density of 0.

Similarly, trapping rates and frequency of observation suggested that the population size of Pampas foxes was greater than that of skunk, lesser grison, and Geoffroy's classifictaion Leopardus geoffroyi in southern Pampas Luengos Vidal et al. Classification ratios favor males.
