Abstract

Human activities are having increasingly devastating effects on the health of marine and terrestrial ecosystems. Studying the adaptive responses of animal species to changes in their habitat can be useful in mitigating this impact. Vultures represent one of the most virtuous examples of adaptation to human-induced environmental changes. Once dependent on wild ungulate populations, these birds have adapted to the epochal change resulting from the birth of agriculture and livestock domestication, maintaining their essential role as ecological scavengers. In this review, we retrace the main splitting events characterising the vultures' evolution, with particular emphasis on the Eurasian griffon . We summarise the main ecological and behavioural traits of this species, highlighting its vulnerability to elements introduced into the habitat by humans. We collected the genetic information available to date, underlining their importance for improving the management of this species, as an essential tool to support restocking practices and to protect the genetic integrity of . Finally, we examine the difficulties in implementing a coordination system that allows genetic information to be effectively transferred into management programs. Until a linking network is established between scientific research and management practices, the risk of losing important wildlife resources remains high.

摘要

人类活动正对海洋和陆地生态系统的健康产生越来越具有毁灭性的影响。研究动物物种对其栖息地变化的适应性反应有助于减轻这种影响。秃鹫是适应人类引起的环境变化的最典型例子之一。这些鸟类曾经依赖野生有蹄类动物种群,如今已适应了农业和家畜驯化诞生所带来的时代变迁,继续发挥着生态清道夫的重要作用。在这篇综述中,我们追溯了表征秃鹫进化的主要分化事件,尤其着重于欧亚兀鹫。我们总结了该物种的主要生态和行为特征,强调了其对人类引入栖息地的因素的脆弱性。我们收集了迄今为止可用的遗传信息,强调其对改善该物种管理的重要性,这是支持种群补充实践和保护其遗传完整性的重要工具。最后,我们审视了实施一个能让遗传信息有效转化为管理计划的协调系统所面临的困难。在科研与管理实践之间建立起联系网络之前,失去重要野生动物资源的风险依然很高。
