Abstract:
... Palaeoenvironmental information collected from zooarchaeological (guanaco exploitation) and palynological (pollen and fungal remains) records from Tierra del Fuego and Isla de los Estados allowed us to reconstruct the natural scenarios during the Holocene to better understand the human behavioral patterns and cultural changes. We have seen that changes in subsistence and guanaco exploitation would ...

The Southern Andean Precordillera constitutes an interesting environment to analyze the species’ presence across the altitudinal gradient. Diet selection and habitat use were studied in the summit plateau, characterized by rigorous conditions and vegetation ...

Abstract:
... Prosopis flexuosa (Fabaceae), a key species in desert environments, provides ecosystem services whereby it mitigates desertification and supports biodiversity conservation. To understand the relative importance of drivers of species diversity and structure of P. flexuosa-dominated woodland at different scales, we propose (1) to assess whether species richness is affected by predictors such as prod ...

Abstract:
... Sheep depredation by puma (Puma concolor) is a socio-environmental problem that has intensified in recent decades in Patagonia. A bounty system to control this carnivore is implemented in Chubut province (central Patagonia), whereas alternative measures to mitigate the conflict are still in progress. A common recommendation to limit livestock depredation by large carnivores is to maintain suitable ...

The aim of this analysis was to compare dung-pile use by territorial males with the use by females and young in family groups, and by bachelor males. Although territorial males showed the highest dung-pile use, all individuals dropped feces on piles frequently, in contrast to what was previously ...

The optimal foraging theory postulates that as animal population density increases, the progressive decline in preferred forage availability results in changes in diet composition and widening of dietary niche breadth. For sedentary guanaco populations, some authors proposed a mechanism of population density limitation below the environmental carrying capacity, mediated through territoriality. Und ...

Avoidance behavior is a common response of animals to this type of perturbation, preventing access to areas rich in resources. The effects of roads on ungulates have not been studied in South America extensively, especially in arid environments. We have studied the space use by ungulates in relation to roads, using a dung heap c ...
