Taxonomic, phylogenetic and functional diversity patterns of Saturniidae moth communities along a tropical forest recovery gradient in Ecuador

We studied patterns of taxonomic, functional and phylogenetic diversity as well as community composition of Saturniidae, as one of the most conspicuous and well-studied families of moths. Our study covered a forest recovery gradient from active agriculture via early and advanced stages of regrowth to old-growth rainforests in the lowland Chocó region of Ecuador.
Saturniidae diversity patterns did not follow the hypothesized increase from agriculture to old-growth forest, but instead, highest taxonomic and functional diversity was found in early regrowth, and highest phylogenetic diversity in active agriculture. Diversity differences along the forest recovery gradient were overall weak and occurred mainly when focusing on common and dominant species, but community composition showed a gradual turnover with strongest differences between old-growth forest and active agriculture.

本研究以最为醒目且研究最为充分的蛾类类群之一——大蚕蛾科(Saturniidae)为研究对象，探讨了其分类多样性、功能多样性与系统发育多样性的分布格局，以及群落组成特征。本研究的采样覆盖了厄瓜多尔低地乔科地区的森林恢复梯度，涵盖了从当前耕作农田、次生演替早期、次生演替晚期直至原始雨林的生境类型。

大蚕蛾科的多样性分布格局并未遵循"从农田到原始雨林多样性逐步升高"的研究假设，反而呈现出分类与功能多样性峰值出现在次生演替早期生境，而系统发育多样性峰值则出现于当前耕作农田中的模式。沿森林恢复梯度的多样性差异整体较弱，且仅在聚焦常见种与优势种时才会显现；但群落组成则呈现出逐步的物种更替，其中原始雨林与当前耕作农田之间的群落差异最为显著。
