Nitrogen deposition reduces lichen cover and soil pigment content in biocrusts from a semiarid Mediterranean shrubland

Biocrust community data (mosses, lichens and cyanobacteria) from 2008 to 2012 from a N addition experiment in central Spain. N was added at four rates (0, 10, 20 and 50 kg N ha-1 yr-1). Shrub cover and soil chemistry data are also provided.

本数据集包含西班牙中部一项氮添加试验于2008至2012年间采集的生物结皮（Biocrust）群落数据，涵盖苔藓、地衣与蓝藻类群。该试验设置了4个施氮梯度：0、10、20及50 kg N ha⁻¹ yr⁻¹。本数据集同时提供灌木覆盖度与土壤化学相关数据。
