Fishless lakes, food webs, fish introductions, shallow lakes. |
My interest is centered in the study of continental aquatic ecosystems and, in particular, in ecosystem-level effects of exotic fish introductions in Patagonian shallow lakes. The high environmental variability across the vast geographic gradient of Patagonia, together with its pristine condition, make of this region an ideal setting to develop such research. On the other hand, the meager knowledge of regional lakes and rivers poses a great obstacle to generate and evaluate the effectiveness of alternative ecosystem-based management actions.
A major motivation of my work is to identify factors and processes that shape community assemblages and understand the effects of fish introductions on receiving communities through the study of collections of lakes. My aim is to go beyond the plain identification of particular effects, but to understand mechanisms and processes responsible for the alteration of affected environments. One of the major goals of my work is to generate management tools to promote the rational use of natural resources, considering the recurrent conflicts between conservation and production in Patagonia.
