Plant Evolutionary Ecology Lab


Our research is focused on the ecological and evolutionary mechanisms that cause and maintain the high diversity of flowering plants. Our main interest is in plant interactions with animals and with environmental factors in wild populations. We do field work in tropical, temperate and Mediterranean environments.

Current work combines field and greenhouse observations with genomic markers to study evolutionary potential in natural populations. This is important to understand how populations evolve under natural and human-induced changes such as pollinator declines. 


PhD position on fire ecology and pollination based in Valencia (Spain), starting in 2020.

The student will be co-supervised by Juli Pausas and myself.  For more information on the project and on how to apply, please visit here (in Spanish).
