摘要

在规划目标物种的保护方案时,运动生态学和环境因素是最重要的考虑因素。在这里,我们通过审查与埃及秃鹫Neophron pernopterus相关的现有信息来讨论这个话题,参考意大利南部的剩余繁殖种群,这些种群受到高度保护,是长期圈养繁殖再放养计划的主题。我们描述了中地中海上空的不利风力条件如何使渡海具有挑战性,对缺乏经验的鸟类的生存产生不利影响,并将这些信息与迁徙的埃及秃鹫的计数数据相结合。此外,我们还指出,种群数量少,与迁徙的同种动物相遇的机会少,可能会导致幼年埃及秃鹫走上不利的迁徙路线,并可能对生存产生影响。我们假设这些伴随因素如何间接影响这一小部分人口的长期生存,主要受人为威胁的影响。我们还讨论了在补充库存计划的框架内,同样的因素实际上是如何影响夏末在意大利南部大陆放生的圈养幼仔的。采用量身定制的放生方法的综合方法,同时考虑到放生鸟类的年龄以及地理和环境因素,可能有助于实现更注重目标和更持久的保护成果,保护这种濒危的食腐动物。

Potential importance of wind patterns and guidance opportunities for the conservation of the Egyptian Vulture Neophron percnopterus in Italy
Summary Movement ecology and environmental factors are topics of paramount importance to consider when planning conservation programmes for target species. Here we discuss this topic by reviewing the available information related to the Egyptian Vulture Neophron percnopterus, with reference to the remnant breeding population of Southern Italy, of high conservation concern and subject of a long-term captive-breeding re-stocking programme. We describe how adverse wind conditions over the Central Mediterranean Sea make the sea-crossing challenging with detrimental effects on the survival of inexperienced birds, and coupled this information with count data of migrating Egyptian Vultures. Furthermore, we indicate how low population size and scarce opportunities in meeting migrating conspecifics could potentially lead juvenile Egyptian Vultures to follow unfavourable migratory routes, with possible repercussions on survival. We postulate how these concomitant factors could be indirectly influencing the long-term survival of this small population, principally affected by anthropogenic threats. We also discuss how the same factors could actually be affecting captive-bred young individuals released in late summer in southern continental Italy, in the framework of the restocking programme. An integrative approach with tailor-made release methods, which also takes into account the age of released birds and geographical and environmental factors, would likely be useful for a more goal-oriented and long-lasting conservation outcome, for the preservation of this endangered scavenger.

期刊介绍: Bird Conservation International is a quarterly peer-reviewed journal that seeks to promote worldwide research and action for the conservation of birds and the habitats upon which they depend. The official journal of BirdLife International, it provides stimulating, international and up-to-date coverage of a broad range of conservation topics, using birds to illuminate wider issues of biodiversity, conservation and sustainable resource use. It publishes original papers and reviews, including targeted articles and recommendations by leading experts.
