Fitness consequences of anthropogenic subsidies for a partially migratory wading bird

Human activities are forcing wildlife to confront selective pressures different from those under which they evolved. In seasonal environments, migration evolved as an adaptation to fluctuating resource availability. Anthropogenic subsidies modify resource dynamics by providing a steady food source that is not subject to seasonality. Globally, many migratory populations are becoming increasingly resident in response to food supplementation. While these population-level shifts are assumed to arise from changing fitness consequences of individual behavior in response to resource dynamics, these mechanisms are often difficult to quantify and disentangle. Here, we quantified fitness consequences of responses to anthropogenic subsidies in partially migratory wood storks (Mycteria americana) in the heavily urbanized southeastern U.S. First, we tested whether individual migratory behavior is linked to different responses to anthropogenic subsidies. Second, we quantified fitness consequences of ..., , , # Fitness consequences of anthropogenic subsidies for a partially migratory wading bird
