Vieira et al. - Founders richness and late-stage community Data.xlsx

This dataset was used to follow diversity and community structure at experimental units founded by single or multiple species, testing the following hypothesis: 1) species diversity at late-stage is positively affected by founders diversity and 2) the occurence of exotic species is negatively affected by founders diversity. To test the generality of these hypothesis, we used three different common groups in subtidal sessile communities: colonial ascidias, arborescent bryozoans and encrusting bryozoans. Dataset show richness of taxa, cover area as a proxy of relative abundance, the occurence of founder species on high and low founder richness treatments along succession, and the occurence of exotic species at late-stage succession.

本数据集用于追踪由单物种或多物种构建的实验单元中的群落多样性与群落结构，旨在检验以下两项假说：1）演替后期的物种多样性会受到初始建立者物种多样性的正向影响；2）外来物种的出现会受到初始建立者物种多样性的负向影响。为检验这些假说的普适性，我们选取了潮下带固着群落中的三类常见类群：群居被囊动物（colonial ascidias）、树状苔藓虫（arborescent bryozoans）以及结壳苔藓虫（encrusting bryozoans）。本数据集包含类群丰富度、作为相对丰度替代指标的覆盖面积、高低初始建立者丰富度处理下建立者物种在演替过程中的出现情况，以及演替后期外来物种的出现情况。
