Mammal and bird diversity in a system of protected areas in Argentina

Abstract

The main driver of biodiversity loss and subsequent decreases in ecosystem functionality is undeniably human interference, destruction and encroachment. The creation and establishment of protected areas serve as tools for guaranteeing biodiversity conservation. In this study, we examined the diversity of medium- and large-sized mammals and flightless walking birds that are supported by a protected area system, the Ischigualasto–Talampaya system, and its area of influence. We set up 106 camera traps and analysed all data with rank–abundance curves and Hill numbers as a measure of diversity. Species richness was lower in protected areas, unlike in the buffer zone, due to the absence of domestic species. Native species were present all over the area, but with variations in their abundances, showing that the presence of domestic species in low densities would not negatively affect the richness of native species, but would indeed affect their abundance.
