I am an ecologist focusing in the complexities generated by land use changes through degradation/deforestation processes in the natural habitats and fauna of South American ecosystems. I focused on questions related to bird ecology, foraging behavior and their relation to land use changes in the North Argentinean Yungas and Chaco regions. I am interested in the trade-offs between food production and conservation and conservation strategies to reconcile these objectives. I explored the trade-offs between economic production, biodiversity and carbon stocks using optimization and spatial analysis oriented to land use planning for the dry Chaco. I’m also interested in exploring ideas on how to connect the processes behind bird abundances and distribution patterns with land use change processes.
