The SDM-glm models are species distribution models of 20567 terrestrial vertebrate species (2739 amphibians, 8115 birds, 5711 reptiles, and 4002 mammals) using Generalized Linear Models as model algorithm. SDM-glm are statistical models, which were calibrated using a 30-year average (1981-2010) of the GSWP3-W5E5 observed climate input data set and IUCN and BirdLife range maps of each vertebrate species. The models are then projected to simulated historical, current and future 30-year average climate data from ISIMIP3b, and where filtered using species specific habitat preferences resulting in probabilities of occurrence.

Information for the model SDM-GLM is provided for the simulation rounds shown in the tabs below. Click on the appropriate tab to get the information for the simulation round you are interested in.
