【 摘 要 】

1000 freshwater insect species (especially Odonata, Coleoptera, Trichoptera, Ephemeroptera; OCTE) in 26 Geographical Caribbean Units (GCU) and quantified local filtering (climate heterogeneity, annual rainfall, annual temperature), geography (area, distance from the mainland) and emergence age as a proxy for island ontogeny. We investigated the relative role of these variables on the species richness, endemism and composition of the units using island species-area relationship (ISAR), generalised linear modelling (GLM) and nonmetric multidimensional scaling (NMDS). In addition, we analysed the spatial patterns of species richness and composition using Moran’s I 60%) found in the Caribbean freshwaters calls for more conservation effort in managing these highly threatened freshwater environments.
