This week EEB welcomes Dr. Anne Charmantier from the Centre d’Ecologie Fonctionnelle et Evolutive (CEFE) in Montpellier, France:
Testing for local adaptation in wild passerines: from phenotypic to genomic approaches
I will present two projects that have started with the revelation, based on long-term individual monitoring, of phenotypic differences between close populations of Paridae. First, strong phenotypic divergence was measured for many morphological, life history and behavioural characters in blue tits from deciduous versus evergreen habitats in the south of France, with populations as close as 5 km. Second phenotypic differences were described between great tits living in an oak forest versus an urban environment, as well as along an urbanisation gradient. In both case studies, I will show how we have pieced together our knowledge on gene flow, natural selection, quantitative genetic variation and genomic footprints of selection to test whether the strong phenotypic differences witnessed could be attributed to local adaptation, thereby supporting the existence of different ecotypes at a spatial scale smaller than the species dispersal distance.
This seminar will be held on Thursday in the BioSciences Complex, Room 3110, from 12:30-1:30pm. Light refreshments are served starting at 12:15.
