Data on arthropod frequencies, traits and R code

We compared an indicator for community homogenization, the distance decay slope between four local habitats of increasing land-use intensity, from forests to managed grasslands, to arable lands and to settlements, imbedded in near-natural, agricultural and urban regions. This comparison was based on 12k arthropod species from 400 families, covering an area of 70.500 km². <br>Available data includes arthropod frequency data, trait (body size and mobility) data averaged over families, and the used R code for the project.

本研究针对群落同质化（community homogenization）的相关指标展开对比分析，该指标为土地利用强度依次递增的四种局地生境（从森林、管理型草地、耕地至居民点）嵌入近自然、农业及城市区域后所计算得到的距离衰减斜率。本次分析基于涵盖400个科的12000种节肢动物（arthropod），研究覆盖总面积达70500平方千米。<br>本研究公开可用的数据包含节肢动物多度数据、按科平均的功能性状（体型大小与移动能力）数据，以及本项目所用的R代码。
