A major challenge for conservation is to identify importantsites to efficiently safeguard biodiversity. The largestsystematically identified network of important sites forconserving species is BirdLife International's Important Birdand Biodiversity Area (IBA) network.IBAs are sites of international significance for theconservation of birds and other biodiversity. Over 13,000IBAs, including terrestrial, freshwater and marineenvironments, have been identified in >200 countries.However, some national inventories are dated, while therehave been major revisions to our understanding ofspecies's distributions, populations, and threats.Furthermore, only 21% of IBAs are completely covered byprotected areas and more than 250 sites have beenassessed as 'IBAs in Danger'.The effectiveness of IBAs in contributing to the persistenceof biodiversity has not previously been fully assessed. Theaim of this PhD is to assess the adequacy of the IBAnetwork in conserving birds and other aspects ofbiodiversity, and to identify priorities for its futureexpansion. The objectives are to:i) measure the effectiveness of IBAs at capturing avianbiodiversity at global scales;ii) identify shortfalls, in species, communities, and habitatsin the IBA network, the reasons for these, and priorities forfilling them;iii) assess patterns of habitat loss, fragmentation, edgeeffects & habitat degradation within IBAs and explore thepotential impacts on the effectiveness of the network forconserving avian species and communities;iv) assess the degree to which IBAs conserve otheraspects of biodiversity, including non-avian taxa,ecosystems, evolutionary heritage, and functional diversity.The project will be co-supervised by BirdLife and will usediverse data sets (e.g. IBA trigger species lists, species'range maps, Area of Habitat maps, point-occurrence datafrom e-Bird, and data from systematic monitoring of IBAs).It would suit a student with a keen interest in practicalconservation theory, birds, global biodiversity challenges,and data handling.

保护的一个主要挑战是确定重要的地点，以有效地保护生物多样性。国际鸟盟的重要鸟类和生物多样性区（IBA）网络是最大的系统性确定的重要物种保护区网络。IBA是对鸟类和其他生物多样性具有国际意义的保护区。在200多个国家，已经确定了超过13,000种IBAs，包括陆地，淡水和海洋环境。然而，一些国家的清单是过时的，同时我们对物种分布，种群和威胁的理解也有重大的修改。此外，只有21%的IBAs完全被保护区覆盖，250多个地点被评估为“处于危险中的IBAs”。IBAs在促进the persistence持久of biodiversity生物多样性has not been previously以前been fully充分assessed评估.该博士学位的目的是评估IBAnetwork在保护鸟类和生物多样性的其他方面的充分性，并确定其未来扩展的优先事项。其目标是：i）测量IBAs在全球范围内捕获鸟类生物多样性的有效性;ii）确定IBA网络中物种、群落和栖息地的不足，其原因，以及填补这些不足的优先事项;iii）评估IBAs内栖息地丧失、破碎化、边缘效应和栖息地退化的模式，并探索对保护鸟类物种和群落的网络有效性的潜在影响; iv）评估IBAs保护生物多样性其他方面的程度，包括非鸟类分类群、生态系统、进化遗产和功能多样性。该项目将由国际鸟盟共同监督，并将使用各种数据集（例如，IBA触发物种列表、物种范围地图、栖息地地图、来自e-Bird的点出现数据，和IBAs系统监测的数据）。它将适合对实践保护理论、鸟类、全球生物多样性挑战和数据处理有浓厚兴趣的学生。
