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.<br>Dataset includes all data and R script to peform analyses.Community data of Saturniidae: Saturniidae_2021_2022final.csvEnvironmental data: Environment.csvPhylogeny of Saturniidae: Phylo_Saturniidae_rooted.nwkTraits of Saturniidae: Saturniidae_Traits_reduced3.csvR Script: Seibold_etal_Saturniidae_script_public.R Supporting R function loaded during analyses: DivPairCoverage_V2.R<br><br>

本研究以大蚕蛾科（Saturniidae）——这一最醒目且研究最为充分的蛾类类群之一——为研究对象，系统探究了其分类多样性、功能多样性、系统发育多样性的分布格局以及群落组成特征。
本研究覆盖厄瓜多尔低地乔科（Chocó）地区的森林恢复梯度，样地涵盖从人工农田、早期次生林、晚期次生林直至老龄原始雨林的多种生境类型。
大蚕蛾科的多样性格局并未遵循“从农田到老龄林多样性逐步升高”的预设假说：其分类多样性与功能多样性的峰值出现在早期次生林中，而系统发育多样性的最高值则见于人工农田中。
森林恢复梯度上的多样性差异整体较弱，且仅在聚焦常见种与优势种时才表现显著；但群落组成呈现出逐步更替的趋势，其中老龄原始林与人工农田间的群落差异最为显著。
