restricted dispersal reduces the strength of spatial density dependence in a tropical bird population.spatial processes could play an important role in density-dependent population regulation because the disproportionate use of poor quality habitats as population size increases is widespread in animal populations-the so-called buffer effect. while the buffer effect patterns and their demographic consequences have been described in a number of wild populations, much less is known about how dispersal affects distribution patterns and ultimately density dependence. here, we investigated the role of ...200818285284
inbreeding and loss of genetic variation in a reintroduced population of mauritius kestrel.many populations have recovered from severe bottlenecks either naturally or through intensive conservation management. in the past, however, few conservation programs have monitored the genetic health of recovering populations. we conducted a conservation genetic assessment of a small, reintroduced population of mauritius kestrel (falco punctatus) to determine whether genetic deterioration has occurred since its reintroduction. we used pedigree analysis that partially accounted for individuals o ...200818294297
anthropogenic natal environmental effects on life histories in a wild bird population.recent work suggests that the environment experienced in early life can alter life histories in wild populations, but our understanding of the processes involved remains limited. since anthropogenic environmental change is currently having a major impact on wild populations, this raises the possibility that life histories may be influenced by human activities that alter environmental conditions in early life. whether this is the case and the processes involved remain unexplored in wild populatio ...201424560573
