We present the first actualistic study of the rodents consumed by the South American fox Lycalopex culpaeus smithersi (Achala culpeo fox), a subspecies of the culpeo fox that is endemic to the highlands of central Argentina. We provide a taphonomic characterization of this canid based on digested micromammal bones, and compare it to other carnivore...

Understanding the mechanisms that drive phenotypic divergence along climatic gradients is a long-standing goal of biogeography. To fulfil this objective, we tested if neutral and/or adaptive effects drive phenotypic diversification. We quantified the effects of neutral evolution and natural selection on morphological variability of a well-suited ma...

A total of 111 samples (43 faeces and 79 gastrointestinal tracts) of 14 wild carnivore species from 12 Argentine provinces were analyzed. Helminth eggs were identified in 73% of the faecal samples and adult worms were recovered from 81% of the gastrointestinal tracts. We found 19 helminth species. Among the most frequent findings were parasites of...

RESUMEN. Los predadores tope son las especies más afectadas por las alteraciones en las redes tróficas de origen antrópico. Examinamos la dieta de dos carnívoros simpátricos (puma Puma concolor y zorro colorado Pseudalopex culpaeus smithersi) y evaluamos la importancia de los roedores en términos energéticos, ya que los métodos tradicionales tiende...

This study presents the first data on the diet of the puma ( Puma concolor ) and an endemic culpeo fox ( Pseudalopex culpaeus smithersi ) in the high mountains of central Argentina, based on scat analysis. Trophic interactions of both carnivores were examined from 2003 to 2008 inside a protected area after livestock removal. A total of 604 scats we...

We present the 1st data on the diet of the Andean mountain cat (Leopardus jacobitus), and the 1st on the colocolo (Leopardus colocolo) and the culpeo (Lycalopex culpaeus) in high-altitude deserts of northern Argentina, based on fecal analysis. Feces of Andean mountain cats and colocolos were distinguished by DNA analysis. The Andean mountain cat (n...

ABSTRACT Livestock can affect the feeding ecology of carnivores either directly, by becoming potential prey, or indirectly, by modifying,selection of other prey. Selection of other prey is modified through the negative effects of livestock on food and cover, which reduces density and increases vulnerability of wild prey. Pseudalopex culpaeus smithe...
