The jaguar (Panthera onca) is a near-threatened species (IUCN 2010) and has suffered a 54% reduction of historic range (Rabinowitz & Zeller 2010). This species was formerly found from the southwestern United States down through Patagonia; today, the range has contracted to northern Mexico through northern Argentina. Proactive conservation efforts spearheaded by the Panthera Corporation now focus on establishing a range-wide corridor network. The main goal of the corridor network is to restore and maintain genetic connectivity between otherwise fragmented populations (Sanderson et al. 2005; Rabinowitz & Zeller 2010). Current research must therefore focus upon the characteristics of jaguar populations, the identification of sources versus sinks, and the human activities that impact them.
Project Title: Population Persistence of Jaguar (Panthera onca) in the Brasilian Pantanal
This project aims to quantify population vital rates in sites of differing land use and human pressures—namely, a protected national park and a working cattle ranch. A habitat-based population viability analysis (PVA) will be developed from these data, and allow for inter-site comparisons in population characteristics. This study will use a combination of non-invasive field surveys, GPS-collared animals and genetic techniques to obtain demographic data necessary to develop the PVA. Genetic and demographic data will be coupled to strengthen inferences on dispersal, as well as inter- and intro-population reproductive rates. The reproductive data will be used to identify source versus sink populations, while the PVA will be used to explore probable future scenarios under alternative management techniques (Quigley & Crawshaw 1992).
