Human activities influence the direction and magnitude of local biodiversity change over time

摘要: In recent decades, environmental drivers of community change have been associated with changes in biodiversity from local to global scales. Here we evaluate the role anthropogenic marine ecosystems as species richness a meta-analysis novel dataset temporal richness. We paired data 144 sites large-scale derived geospatial databases: human cumulative impacts, sea surface temperature change, nutrient loading, and invasion potential. Three specific (nutrient inputs, rate linear non-native potential) explained patterns change. show that these opposing effects on trends, some cases, contrasting directions can offset each other yield observations no net across localities. Further, long-term studies reveal different are not observed short-term studies. These findings begin explain high variability diversity trends at suggest is predictable phenomenon many time-series be when impacts considered.
