New publication: The Zooplankton international geospatial dataset: A global repository of spatiotemporal fresh water zooplankton community composition data from lakes and reservoirs to support ecological research.
Zooplankton transfer substantial energy in aquatic food webs and are used as indicators of environmental change. Syntheses of zooplankton community dynamics globally require datasets that span a wide range of environmental gradients; however, these datasets are limited due to methodological differences across pro grams, taxonomic inconsistencies, and a lack of standardized metadata. To reconcile these challenges, we cre ated the Zooplankton International Geospatial (ZIG) dataset, which includes original zooplankton, water physical and chemical variables, and lake morphometric data from 311 inland lakes and reservoirs. ZIG includes waterbodies ranging in size from 0.005 to 82,100 km2 and spanning broad latitudinal ( 47.26 to 64.90) and longitudinal ranges ( 165.04 to 176.53). Temporal coverage for individual waterbodies ranges between 1 and 60 yr with sampling frequency ranging from annually to weekly. With its extensive coverage and content, we consider ZIG to be a cornerstone for future investigations of global scale lake biodiversity change.
