Drivers of phylogenetic assemblage structure of the Furnariides, a widespread clade of lowland Neotropical birds
收藏资源简介:
Species co-occurrence in local assemblages is shaped by different processes at different spatial and temporal scales. Here we focus on historical explanations and examine the phylogenetic structure of local assemblages of the Furnariides clade (Aves: Passeriformes), assessing the influence of diversification rates on the assembly and species co-occurrence within those assemblages. Using 120 local assemblages across Bolivia and Argentina and a nearly complete phylogeny for the clade, we analyzed assemblage phylogenetic structure applying a recently developed model (DAMOCLES) accounting for the historical processes of speciation, colonization and local extinction. We also evaluated how diversification rates determine species co-occurrence. We found that the assembly of Furnariides assemblages can largely be explained by speciation, colonization and local extinction without invoking current local species interactions. Phylogenetic structure of open habitat assemblages mainly showed cluste...
局域群落中物种的共存格局受不同空间与时间尺度下的多样过程共同塑造。本研究聚焦历史成因解释,以灶鸟类群(Furnariides clade,鸟纲Aves:雀形目Passeriformes)的局域群落为研究对象,分析其系统发育结构,并评估多样化速率对群落构建以及群落内物种共存的影响。本研究利用覆盖玻利维亚与阿根廷的120个局域群落,以及该类群近乎完整的系统发育树,采用新近开发的DAMOCLES模型分析群落系统发育结构,该模型可纳入物种形成、定殖与局域灭绝等历史过程。同时,本研究还探讨了多样化速率如何调控物种共存格局。研究结果显示,灶鸟类群落的构建过程在很大程度上可通过物种形成、定殖与局域灭绝来解释,无需引入当前的局域物种间相互作用。开阔生境群落的系统发育结构主要表现为集群(cluste...)
