I have a strong interest in the evolution and maintenance of individual variations within populations, and especially in the role of consistent phenotypic correlations, defining behavioural or physiological syndromes, in maintaining individual variations.
I first addressed that question during my Master years, by studying physiological traits and alternative life history strategies correlated with plumage coloration in feral pigeon Columbia livia.
Currently, I am investigating the role of oxidative stress and senescence in shaping the relationship between dispersal behaviour and life histories. My project is based on correlative and experimental approaches on a fragmented population of collared flycatchers Ficedula albicollis. A first part of the project will be to investigate potential correlations between dispersal, metabolic rate and oxidative stress through physiological measures combined with experimental manipulation of reproductive or locomotive effort. The second part will address the consequences of such physiological syndrome on senescence and life history strategies, using the 30-year demographic database available for that population.
The project implies two to three months fieldwork in our study site on Gotland island, Sweden, from mid-April to mid-July. Students and technicians interested in taking part should write to Blandine Doligez who is responsible for the French part of the program. The project also offers opportunities for Master projects focusing on lab analyses (telomere length, metabolic rate through doubly labelled water, ROS production, antioxidant capacity…) or data analyses. Internships would then take place in Lausanne (Switzerland), Lyon (France) or Strasbourg (France).
