My research is related to understanding and mitigating the effects of the rapid expansion of intensive crop and livestock production on wildlife in austral South America. Within this context I am principally interested in the ecology and conservation of jaguar (Panthera onca) and puma (Puma concolor) and their functional role in determining trophic relationships within the Chaco and Pantanal ecosystems of western Paraguay, This relates to quantifying prey abundance and diversity and trophic relationships with meso-carnivores and facultative and obligate scavengers (vultures). This research includes the integration with the decision making process through structured decision making and adaptive management to resolve conflict between carnivores and livestock production, as well as the management of harvested species.
Additionally, I am interested in the ecology and conservation of Galliformes and Tinamous as these taxa are culturally and economically important and serve as excellent model organisms for understanding the ecological effects of agricultural and other land uses. Species in these taxa are very sensitive to anthropogenic factors that affect nest, brood, and adult survival by determining food and habitat availability, habitat configuration, the community and abundance of predators and harvest. Through this research I am actively involved in the IUCN Galliformes Species Specialist Group and serve on its Co-chair’s Advisory Board.
