Abstract

Anthropogenic changes in natural landscapes are identified as a major driver of biodiversity loss worldwide. Consequently, important ecosystem functions, such as seed dispersal by animals, can be lost, which threaten the stability of essential ecological processes. Given the current scenario of large seed disperser's loss, secondary dispersal by ants has been identified as an important alternative to mitigate the impacts caused by human changes. However, empirical evidence shows contradictory effects of anthropogenic disturbances on diaspore removal by ants. Here, we conducted a global meta-analysis from 22 studies (65 comparisons) comparing diaspore removal by ants in disturbed versus preserved areas to investigate general trends to different anthropogenic disturbances. Specifically, we evaluate: (i) the effects of anthropogenic disturbances on diaspore removal by ants comparing temperate and tropical regions, and (ii) comparing different disturbance types (agriculture related disturbances, fragmentation, mining, fire, etc.) on diaspore removal by ants. We found an overall negative effect of anthropogenic disturbances on diaspore removal by ants (26% decrease), both in temperate and tropical regions (38% and 19% decrease, respectively). In addition, diaspore removal by ants responded negatively to disturbances related to fragmentation (24% decrease) and mining (83% decrease). However, we found no evidence of effects in areas subjected to agricultural processes (0.9% decrease). Our findings suggest that human disturbances might compromise crucial early stages to the natural regeneration in ecosystems such the seed dispersal.

人为干扰对蚂蚁去除一水硬铝石的影响：一项荟萃分析

自然景观的人为变化被认为是全球生物多样性丧失的主要驱动因素。因此，重要的生态系统功能，如动物的种子传播，可能会丧失，这威胁到基本生态过程的稳定性。鉴于目前大量种子传播者消失的情况，蚂蚁的二次传播已被确定为减轻人类变化造成的影响的重要替代方案。然而，经验证据表明，人为干扰对蚂蚁清除一水铝石的影响相互矛盾。在这里，我们对22项研究(65项比较)进行了全球荟萃分析，比较了蚂蚁在受干扰地区和保护地区的一水硬石清除情况，以调查不同人为干扰的总体趋势。具体而言，我们评估:(i)比较温带和热带地区的人为干扰对蚂蚁一水硬石迁移的影响，以及(ii)比较不同类型的干扰(农业相关干扰、破碎化、采矿、火灾等)对蚂蚁一水硬石迁移的影响。我们发现，在温带和热带地区，人为干扰对蚂蚁清除一水硬石的总体负面影响(减少26%)(分别减少38%和19%)。此外，蚂蚁对一水硬石的清除对破碎(减少24%)和采矿(减少83%)相关的干扰呈负反应。然而，我们没有发现农业加工地区的影响证据(减少0.9%)。我们的研究结果表明，人类干扰可能会破坏生态系统自然再生的关键早期阶段，如种子传播。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
