Research Interests

I am a Level II Scientist in the National Science and Technology Council of Paraguay (CONACYT), a Co-principal Investigator of the Jaguar Program within the Paraguayan NGO Guyra Paraguay, a member of the Paraguayan Scientific Society, and adjunct faculty in the School of Natural Resources at the University of Nebraska-Lincoln. I am also a member of the reserach team of Proyecto Pantano, a project focused on the research and conservation of the Marsh deer (Blastocerus dichotomus), the largest deer in South America, in the Rio de la Plata delta in Argentina.

My research interests concern understanding the effects of agricultural land use on wildlife by understanding the processes that determine species abundance and movements and community composition across landscapes and regions. My research centers upon the rigorous estimation of wildlife population parameters and the use of structured decision making (SDM) and adaptive resources management (ARM) in investigating and managing in an integrative manner:

The ecology and conservation of apex predators and their role in organizing and determining the functionality of terrestrial systems
The movement ecology of carnivores and ungulates and how it is affected by environmental and anthropogenic factors

Estimation of prey species abundance and community diversity in the context of apex predator needs
The ecology of terrestrial gamebirds and using those species as model organisms to investigate both the trophic effects of differing compositions of predator communities and the effect of land management practices
Optimal decision making in the management of harvested species
Decision making in wildlife-human conflict, in particular mitigating conflict between livestock production and large carnivores.

My current 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 Gran Chaco and Pantanal ecosystems of western Paraguay employing structured decision making and adaptive management.

This includes the quantification of prey abundance and diversity and trophic relationships with meso-carnivores and facultative and obligate scavengers (vultures). Moreover, this incorporates research on understanding space use and resource selection of jaguar and puma in western Paraguay in the context of anthropogenic and environmental factors. Additioanlly, through my incorporation into Proyecto Pantano, I have become increasingly involved with the research on the movements and abundance of the Marsh deer in Argentina.

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 effects of agricultural and other land uses. These species 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.
