WELCOME - My research seeks to understand mechanisms driving patterns and processes in freshwater and coastal ecosystems, and how biological communities and ecosystems respond to anthropogenic impacts such as modification of natural hydrologic regimes and species invasions. My collaborators and I use a combination of large-scale field studies, experimental manipulations, quantitative functional traits and analyses of long-term databases to identify mechanisms of community assembly, species extirpations and invasions, ecosystem function, and food-web structure and dynamics. Current research is conducted on Great Plains streams in Kansas (USA), large rivers and reservoirs of the Upper Paraná Basin (Brazil), and coastal lagoons of Lagoa do Peixe National Park (Brazil).
