Ecology and evolution of freshwater fishes
My main project is to analyse data from a conservation program of the State of California. Naturally fishless lakes in the Yosemite area were extensively stocked with non-native salmonids to create recreational fishing opportunities, until recent research showed the vast negative impacts of stocking on native biota. This region has therefore been under a large-scale fish eradication program since 2001. I aim at measuring and understanding how fishing can trigger an evolutionary response in salmonid populations by comparing the size of the fish caught with different fishing gears and how environmental condition could mitigate the impact of selection.
My second project is to understand how environmental change and livestock grazing may affect the golden trout population in the golden trout wilderness. To do that I analyse temperature data from different high altitude meadows, with or without cow exclosure.
My third project is to investigate the portfolio effect in the Central Valley chinook salmon, or how variability between subpopulations, and correlations between subpopulations, can help or harm the system resiliency through time.
