Migrating young eagles follow adults for conservation success
Although the lesser spotted eagle is not listed as endangered by the IUCN, BerndUlrich Meyburg from BirdLife Germany (NABU) knows that the graceful bird of prey’s future is far from assured in Germany. Meyburg explains that the German population has dwindled to just 110 breeding pairs in recent decades, largely due to habitat loss and persecution by poachers during their long migration to their...

متن کاملBetween a rock and a hard place: evaluating the relative risks of inbreeding and outbreeding for conservation and management.
As populations become increasingly fragmented, managers are often faced with the dilemma that intentional hybridization might save a population from inbreeding depression but it might also induce outbreeding depression. While empirical evidence for inbreeding depression is vastly greater than that for outbreeding depression, the available data suggest that risks of outbreeding, particularly in ...
متن کاملProtected Areas, Human Livelihoods and Healthy Animals: Ideas for Improvements in Conservation and Development Interventions1
Disease is becoming increasingly recognized as a threat to wildlife conservation, especially for endangered species (Werikhe et al. 1998). Often the threat is increased by diseases that can be transmitted between closely related species such as people and primates or cattle and buffalo. Transmission of such diseases at the interface of protected areas with human settlements can be exacerbated b...
متن کاملPredicting the probability of outbreeding depression.
Fragmentation of animal and plant populations typically leads to genetic erosion and increased probability of extirpation. Although these effects can usually be reversed by re-establishing gene flow between population fragments, managers sometimes fail to do so due to fears of outbreeding depression (OD). Rapid development of OD is due primarily to adaptive differentiation from selection or fix...
