Sara Magalhães
Main Research Interests
My main research interests are the environmental and genetic mechanisms that generate and maintain biodiversity. At the individual level, I am interested in how environmental cues can modify the behaviour of organisms, and how this can cascade down to population dynamics (phenotypic plasticity, behavioral ecology). Moreover, I would like to understand how the environment shapes the genotypic composition of populations in the long term. In particular, how do populations cope with environmental heterogeneity? What are the consequences of adaptation to one environment in terms of the ability to adapt to other environments?
