Climate-diversity relationships underlying cross-taxon diversity of the Africa fauna and their implications for conservation

Aim: Many taxa show remarkable similarities in their diversity patterns and these similarities are commonly used to define large-scale conservation priorities. Here, we investigated the relative importance of contemporary climate and climate change since the Last Glacial Maximum for determining the species richness and rarity patterns of four animal taxa. We assessed the extent to which diversity patterns are congruent across taxa because of similar responses to these climatic aspects and we identify regions that are disproportionately diverse due to their paleoclimatic stability.
Location: Sub-Saharan Africa.
Time period: LGM–contemporary.
Major taxa studied: Mammal, bird, amphibian and dragonfly species.
Methods: Diversity patterns were predicted based on their relationships with contemporary climate and Quaternary climate change, respectively. Climate-diversity relationships were modelled with and without accounting for spatial autocorrelation. For raw and predicted diversity pattern...

目标：许多类群在多样性模式上表现出显著相似性，这些相似性常被用于确定大规模保护优先区域。本研究旨在探究当代气候与末次盛冰期（Last Glacial Maximum）以来气候变化对四种动物类群物种丰富度及稀有性模式的相对重要性。我们评估了因对这些气候因素的相似响应而导致的类群间多样性模式一致性程度，并识别出因古气候稳定性而异常多样的区域。
位置：撒哈拉以南非洲。
时间范围：末次盛冰期（Last Glacial Maximum）至当代。
研究的主要类群：哺乳动物、鸟类、两栖动物及蜻蜓物种。
方法：分别基于多样性模式与当代气候及第四纪气候变化的关系进行预测。在考虑与不考虑空间自相关（spatial autocorrelation）的情况下，对气候-多样性关系进行建模。针对原始及预测的多样性模式...
