Di Maggio, R., Campobello, D., Tavecchia, G. and Sará M. 2016: Habitat- and density-dependent demography of a colonial raptor in Mediterranean agro-ecosystems Biological Conservation, vol 193 pag 116-123. doi:10.1016/j.biocon.2015.11.016
Abstract: Agricultural intensification is considered the major cause of decline in
farmland bird populations, especially in the Mediterranean region. Food
shortage increased by the interaction between agricultural
intensification and density-dependent mechanisms could influence the
population dynamics of colonial birds. We used demographic data on
lesser kestrels (Falco naumanni), a key species of
Mediterranean pseudo-steppes, to understand the importance of land-use
changes and density-dependent mechanisms in the light of its fluctuating
conservation status in the Western Palearctic. Our analysis indicated
an important influence of land uses (artichokes, arable and grassland
fields) and colony size on kestrel survival rates.
