Assessing contributions of deterministic vs. stochastic processes to local species assembly: A field experiment with annual plant-dominated communities in gypsum systems

Here, we provide a dataset from a field experiment designed and performed to assess the contributions of both functional filtering and stochastic (i.e., lack of trait selection) events to assembly processes at a fine spatial scale in a dryland gypsum annual plant-dominated community by evaluating the effects of seed availability (natural soil seed banks vs. seed-free soil) and main biotic filters (biocrusts vs. perennial tussocks) on realised local assemblages.
