MORNING Metacommunity Of freshwateR sNails IN Guadeloupe

This database describes a metacommunity of freshwater snails occupying sites (essentially ponds) distributed over the whole Grande Terre of Guadeloupe and Marie-Galante. Sites were surveyed from 2001 to 2020 - a core of 230 sites were surveyed annually, and the remaining set of sites (78) less frequently. In each site, the density of those 23 species occupying Guadeloupe freshwaters were recorded as density class, and individuals were counted for a subset of sites. For the two parthenogenetic species Melanoides tuberculata and Tarebia granifera, determination was done at the clone level (6 and 2 respectively). In all sites, a set of environmental parameters were recorded. See Dubart et al. (2022, https://doi.org/10.1111/oik.09157) and Pantel et al. (2022, https://doi.org/10.1002/ecm.1515) for the most recent papers making use of MORNING.
