Verónica Méndez, Postdoctoral researcher at the University of Iceland will takle the complex topic of bird migrations.
Abstract: Migratory behaviour can differ markedly amongst individuals within populations or species. Understanding the factors influencing this variation will help to understand and predict the changes in migration routes and distribution that might result from current environmental changes. In particular, we need to know whether individual migratory strategies are consistent through time and the extent to which individuals with similar behaviours occur in the same breeding areas and pair assortatively. Here, we investigate this variation in migratory behaviour in Eurasian oystercatchers breeding in Iceland; a population in which individuals overwintering in and outside of Iceland are present. Our results suggest that individual migratory strategy is consistent in adulthood and determined in early life, reflecting variation in the conditions experienced during this life stage. Consequently, we then explore juvenile migratory behaviour and test associations between juvenile strategies and (1) parental strategies, (2) timing of hatching and fledging and/or (3) natal location.
Verónica is a conservation ecologist interested in understanding the consequences of global environmental change for biodiversity, with a special interest on migratory systems. Her current research focuses on understanding the mechanisms underlying the variation in migratory behaviour and the associated fitness outcomes in a partial migrant population of Eurasian oystercatcher breeding in Iceland.
