Abstract

Understanding the processes that shape biological communities under a variety of perturbations is a central challenge in ecology and conservation. Mammals contribute to critical functional processes of an ecosystem, such as seed dispersal to maintain forest carbon stocks. The analysis of functional diversity, which measures the range and value of the ecological traits of organisms, provides critical information to understanding the link between biodiversity and ecosystem functioning. A growing number of studies have investigated the effects of anthropogenic disturbances on mammalian functional diversity; however, their results are very heterogeneous. Here, we conduct a comprehensive meta‐analysis of the effects of such anthropogenic disturbances on mammalian functional diversity in the tropics. We highlight major trends and analyse the influence of the type of anthropogenic disturbance, subgroups, and the functional diversity index used/applied. Our results indicate a negative effect of anthropogenic disturbances on mammalian functional diversity, particularly on functional richness (FRic) and functional dispersion (FDis). Habitat isolation was the stressor with the strongest effect, while agriculture and urbanisation showed a positive link with functional diversity. These results indicate that anthropogenic disturbances not only affect taxonomic diversity, but also reduce the functional diversity of mammals, which is likely to affect ecosystem functioning and possibly ecosystem service provision.

人为干扰对热带哺乳动物功能多样性影响的荟萃分析
了解生物群落在各种干扰下的形成过程是生态学和自然保护的核心挑战。哺乳动物对生态系统的关键功能过程做出了贡献,例如传播种子以维持森林碳储量。功能多样性可衡量生物生态特征的范围和价值,其分析为了解生物多样性与生态系统功能之间的联系提供了重要信息。越来越多的研究调查了人为干扰对哺乳动物功能多样性的影响;然而,这些研究的结果却很不一致。在此,我们对人为干扰对热带地区哺乳动物功能多样性的影响进行了全面的荟萃分析。我们强调了主要趋势,并分析了人为干扰的类型、亚群以及所使用/应用的功能多样性指数的影响。我们的研究结果表明,人为干扰对哺乳动物的功能多样性,尤其是对功能丰富度(FRic)和功能分散度(FDis)有负面影响。栖息地隔离是影响最大的压力源,而农业和城市化则与功能多样性呈正相关。这些结果表明,人为干扰不仅会影响分类多样性,还会降低哺乳动物的功能多样性,这很可能会影响生态系统的功能,甚至可能影响生态系统服务的提供。

期刊介绍: Mammal Review is the official scientific periodical of the Mammal Society, and covers all aspects of mammalian biology and ecology, including behavioural ecology, biogeography, conservation, ecology, ethology, evolution, genetics, human ecology, management, morphology, and taxonomy. We publish Reviews drawing together information from various sources in the public domain for a new synthesis or analysis of mammalian biology; Predictive Reviews using quantitative models to provide insights into mammalian biology; Perspectives presenting original views on any aspect of mammalian biology; Comments in response to papers published in Mammal Review; and Short Communications describing new findings or methods in mammalian biology.
