Evolutionary history of grazing and resources determine herbivore exclusion effects on plant diversity
Ecological models predict that the effects of mammalian herbivore exclusion on plant diversity depend on resource availability and plant exposure to ungulate grazing over evolutionary time. Using an experiment replicated in 57 grasslands on six continents, with contrasting evolutionary history of grazing, we tested how resources (mean annual precipitation and soil nutrients) determine herbivore exclusion effects on plant diversity, richness, and evenness. Here we show that at sites with a long history of ungulate grazing, herbivore exclusion reduced plant diversity by reducing both richness and evenness, and the responses of richness and diversity to herbivore exclusion decreased with mean annual precipitation. At short with a short history of grazing, the effects of herbivore exclusion were not related to precipitation but differed for native and exotic plant richness. Thus, plant species’ evolutionary history of grazing continues to shape the response of the world’s grasslands to changing mammalian herbivory.
Global dataset of plant diversity and the spatial variability of grassland biomass from NutNet
While there is strong evidence of diversity effects on temporal variability of productivity, whether this mechanism extends to variability across space remains elusive. Here, we present data from Nutrien Network (www.nutnet.org) that were used to determine the relationship between diferent scales of plant diversity and spatial variability of productivity in 83 grasslands worldwide, and to quantify the effect of experimentally increased spatial heterogeneity in environmental conditions on this relationship. There are two data sets, one for the pre-treatment (observational_data.csv) data, and other for the experimentally increased heterogeneity (increased heterogeneity.csv). In these data sets, study sites contained at least three replicates that originated from blocks each composed of ten 5 m × 5 m plots. In addition, pre-treatment data has a subset of sites in where soil conditions where measured (observational_data_soil.csv) and a version in which data for each site are sumarized and site-level climatic variables obtained from WorldClim (www.worldclim.org) are added. (observational_data_site_climate.csv). If you need any clarification or further information, please contact us.
Data from Globally Consistent Drivers of Plant Microbiome Diversity Across Hosts and Continents
We experimentally manipulated two potential mediators of plant microbiome diversity (soil nutrient supply and herbivore density) at 23 grassland sites spanning global-scale gradients in soil nutrients, climate, and plant biomass. This work used sites that are part of the Nutrient Network Experiment (NutNet; www.nutnet.org), a globally replicated experiment manipulating elemental nutrient supplies and herbivore density in grasslands worldwide. Using amplicon sequencing, we measured relative abundances of fungal (ITS1) and prokaryotic (16S) diversity in the leaves of the most widespread grass at each of 23 grassland sites (focal hosts included 18 grass species from 15 genera).
Plant species percent cover data: Natural Enemies, Plant Diversity and Plant Community Composition
The purpose of this experiment is to determine the influences of natural enemies, including plant pathogenic fungi and insect pests, influence plant community composition, productivity, and diversity over time. The experiment is being conducted in a subset of plots within the Big Biodiversity field, including monoculture, 2-species, 4-species, 8-species, 16-species, and 32-species plots. There are 5 different treatments: foliar fungicide, soil drench fungicide, foliar insecticide, the combination of all pesticides, and nontreated control. The pesticides are applied repeatedly throughout the growing season. Within the plots, community productivity, species composition, percent cover, and pest damage are being quantified over time.
