Dryland plant co-occurrence and associated functional trait data

This data is associated with the MSc dissertation titled "Drivers of plant-plant interactions in global drylands". The first aim of this research was to determine whether climate, edaphic and grazing variables drive plant-plant interactions in global drylands. The second aim was to determine whether the functional traits of plants play a role in determining the interaction outcome. This research uses data collected as part of the BIODESERT project, a global collaborative survey conducted in drylands, led by Dr. Fernando T. Maestre. Data were collected in 97 plots from 29 sites in 10 countries. The data include a co-occurrence survey (used to estimate plant-plant interaction outcomes), a functional trait survey, as well as climate, edaphic and grazing pressure data for each plot.

本数据集与题为《全球干旱地区植物-植物相互作用的驱动因素》的硕士学位论文相关。该研究旨在确定气候、土壤和放牧变量是否驱动全球干旱地区的植物-植物相互作用。第二个研究目标是探究植物的功能性状在决定相互作用结果中是否发挥作用。本研究采用BIODESERT项目所收集的数据进行分析，BIODESERT项目是一项在全球干旱地区进行的全球性协作调查，由Fernando T. Maestre博士领导。数据采集自10个国家29个地点的97个样地。数据包括共现调查（用于估计植物-植物相互作用结果）、功能性状调查，以及每个样地的气候、土壤和放牧压力数据。关于BIODESERT项目和所采用的调查方法的更多详细信息，请参阅以下参考文献：Maestre, F. T., Eldridge, D.
