| Sumario: | Human pressure has substantially transformed the surface of Earth. Habitat transformation enhanced the decrease of many bird species over the centuries. However, some of these species have recovered in the last decades in association with the use of landfills. Feeding at these predictable anthropogenic food subsides reduces the cost of foraging and implies a positive effect on demographic parameters. The high food abundance at landfills may attract a huge number of birds with consequences at population and ecological level. In addition, feeding at landfills is not exempt of some risks. Poor quality food, ingestion of plastics and other pollutants, and proliferation of pathogens may negative affect actual or future life-history traits.Knowing the effects of landfills on several aspects of the ecology of breeding populations is essential to predict and to understand the potential impact of landfill closure. In this way, we can assess management measures of bird populations.The main objective of this thesis is to increase the knowledge about the effect of landfills over breeding populations in the short and the long term. Particularly, we aim to disentangle the impact of the use of landfills in the spatial distribution of breeding pairs, nest-site selection, offspring survival, and the potential effects of landfill closure on white storks (Ciconia ciconia; Linnaeus, 1758)... |
