The fauna of exotic mammals of Argentina represents a good opportunity to understand the dynamics of the invasion process as they represent a diversity of ecological groups and environmental contexts.
Discovery of tetraploidy in a mammal
Polyploidy, or having more than a pair of each type of chromosome, is considered to be unlikely in mammals because it would disrupt the mechanism of dosage compensation that normally inactivates one…
DESERTIFICATION IN CENTRAL ARGENTINA: CHANGES IN ECOSYSTEM CARBON AND NITROGEN FROM IMAGING SPECTROSCOPY
Many arid and semiarid (dryland) regions are subject to desertification from intensive land-use pressures such as cattle ranching. However, the lack of quantitative approaches required to assess…
Utilization of food resources by small and medium-sized mammals in the Monte Desert biome, Argentina
TLDR
Examination of diet composition in a mammal assemblage in the Monte desert, Argentina shows that two main strategies are used by these mammals: medium-sized and small-sized species are herbivores and omnivorous, respectively.
Diet of wild boar (Sus scrofa) in a protected area of Argentina: the importance of baiting
