Colonization-extinction of seabird colonies

Master Thesis subject (30 ECTS)
The processes involving colonization and extinction are crucial to understand metapopulation functioning and their assessment have profound consequences for conservation and management of threatened species. Using a long-term data set covering the period 1974 to present (more than 40 years), we will analyze the extinction-colonization turnover of breeding patches in a population of Audouin's gulls at two spatial scales (within a colony and at mesoscale). We will use data from the Ebro Delta and the Balearic archipelago collected by the host group over those years, and will apply occupancy capture-recapture modelling to estimate probabilities of extinction and colonization. At the same time, we will assess the influence of potential drivers of such processes, such as predatory events, climate extremes, competition, or structural features such as density-dependence.
