The “Eco-evolutionary Genetics subgroup” includes 1 senior researcher (integrated member), hired under the FCT Investigator program, one post-doctoral researcher and one research technician hired by a research project.
We use a multilevel approach that ranges from genes to ecosystems in the context of experimental evolution with the nematode Caenorhabditis elegans and bacteria such as Escherichia coli to understand how adaptation to stressful environments is affected by interactions between organisms. Our three main goals are: i) to understand the role of species interactions in adaptation to stressful abiotic conditions; ii) to find how host-microbe interactions affect the the evolution of aging and which genes underlie this process; iii) to show how frequency- and density- dependent effects resulting from interactions between individuals affect ecological robustness of populations.
