MBM is also a Bayesian analysis; thus it is compatible with specifying prior knowledge ... based biodiversity model obtained from statistical and machine learning methods that associate geographic biodi-versity records (i.e. typically in the form of expert-derived or observed presences, and sometimes absences/non-detections, or measured counts) with the abiotic and/or biotic charac-teristics at those locations (following Elith and Leathwick …
Indeed, correlative models relating ecological metrics to environmental and spatial predictors (henceforth biodiversity models) are now commonplace (see e.g. Franklin, 2010 for a summary of methods used and a framework for spatial prediction of species occurrence) and play a critical role in supporting management and conservation efforts world ...Biodiversity is the variety of living things.
