Title
Urbanization and its ecological and evolutionary consequences for wildlife

Abstract
Humans are dramatically altering environmental conditions throughout the world. One of the most striking man-made environmental changes is the existence and rapidly ongoing spread of urban areas. Besides the fact that urbanization results in a loss of species diversity, many native and non-native species have successfully colonized urban areas. Species that have settled in urban areas may benefit, on the one hand, from the warmer microclimate and from additional anthropogenic food supply in cities. However, they are also confronted with many novel and potentially stressful anthropogenic perturbations. Whereas ecological effects of human-induced habitat alteration are receiving increasing attention, less is known about the evolutionary force of urban settings. We use the partially migratory European blackbird as a model species to investigate the ecological and evolutionary consequences of urban life. Urban populations of this species responded to the environmental conditions of urban ecosystems and have become significantly different from the original forest populations in several aspects: urban blackbird populations have, for instance, a higher breeding density, an extended daily activity pattern, a higher incidence of albinism, a lower migratory tendency, an extended breeding season and are tamer than their rural conspecifics. In this talk I will focus on phenotypic responses in migratory behaviour, timing of reproduction and stress physiology following the colonization of urban areas and will elucidate whether these changes are the result of micro-evolutionary responses to different selection pressures that urban individuals experience or whether they are the result of phenotypic plasticity of individuals exposed to the different environmental conditions.
