Data for the manuscript "Grazer diversity indirectly increases aquatic plant consumption and modifies epiphytic diatom traits"

This is the data for the manuscript "Grazer diversity indirectly increases aquatic plant consumption and modifies epiphytic diatom traits" by Tiina Salo, Marie C. Nordström and Leena Virta submitted for review. The file consists of data from grazing assays along an exposure-gradient consisting of naturally varying grazer communities, aquatic plant species, and epiphytic diatoms. The data includes variables linked to the grazer community (grazer taxa richness, biomass of different taxa and total biomass), the plant community (species used in the grazing assay, grazing, grazing rate and biomass-standardized grazing rates), and the epiphytic diatom community (species richness, shannon diversity, functional dispersion, community weighted mean traits, and dissimilarities in community composition).
