Understanding the importance of genetic variation on the expression of life history traits is central to the understanding of their evolution. However, as for many questions in ecology and evolution, in order to highlight a genetic effect on the expression of a life history trait often requires long-term, individual-based studies of large populations. The long term capture and re-sighting data of the greater flamingo, Phoenicopterus roseus in southern France is an ideal dataset to investigate the link between genetic variation and life history traits. In this seminar I will first present the role of the candidate gene dopamine receptor D4 (DRD4) and microsatellite multi-locus heterozygosity on body condition, survival and dispersal in greater flamingos. I will then describe how I used 454 next generation sequencing to characterize the major histocompatibility complex (MHC) genes in the greater flamingo. This characterization should then enable us to investigate the association between MHC genes and life history traits in this species.
