Dr Adriana Alzate Vallejo
I am a biologist interested in evolutionary ecology, marine biology, macroecology and macroevolution.
In my first years, I studied community assembly of coral and rocky reef fishes in the Tropical Eastern Pacific and I co-founded a NGO to work on marine research and conservation in Colombia (Ecomares). During my PhD, I was interested in the evolutionary and ecological consequences of dispersal. I used several approaches to tackle these questions, such as experimental evolution, simulation modelling and correlational analyses. I worked on two different systems (spider mites and reef fishes) that allowed me to investigate the effects of dispersal at micro-meso-scales (consequences for adaptation and colonization-extinction dynamics) and large scales (consequences for species range size). As part of my sDiv individual postdoc fellowship, I am working on the (macro)eco-evolutionaty drivers of species geographical ranges and diversification. My research focuses on understanding the (macro)ecological and (macro)evolutionary processes responsible for the current biodiversity patterns.
