蜣螂的生态功能由多样性的多个方面决定

为了保护对人类福祉至关重要的生态过程，需要对物种多样性与生态系统功能之间多维关系的机制理解。本文研究了在热带复杂景观Los Tuxtlas生物圈保护区(Los Tuxtlas Biosphere Reserve)中，屎壳虫群落的分类、功能和系统发育多样性，以及屎壳虫群落的聚集机制、森林覆盖率和景观破碎化程度对粪掩埋、土壤挖掘效率和粪蝇幼虫丰度的影响。在代表森林覆盖损失梯度(0%-100%)的15个景观中测量了屎壳郎的功能。从系统发育的角度来看，大型隧道蜣螂的聚集组合在整个景观中显示出最高的粪便掩埋效率。蝇幼虫丰度与屎壳虫的分类多样性和功能均匀性呈负相关。森林覆盖和景观破碎化对粪掩埋效果影响不显著，表明存在高度的功能冗余。粪埋效能主要由选择机制驱动，其中单个或几个系统发育接近的物种不成比例地影响给定的功能。蝇幼虫丰度受一种互补功能效应控制，即每种屎壳虫对蝇幼虫存活率的影响是叠加的。因此，通过不同的机制和不同的多样性维度来维持多种功能。高种类丰富的屎壳郎可能促进害虫蝇控制在热带景观，如Los Tuxtlas生物圈保护区。我们的研究结果强调了评估多样性的多个维度的必要性，因为每个维度都可以同时和对比地作用于物种组合的不同生态功能。
