DM-2.3 | THE RELATIVE EFFECTS OF ABIOTIC AND BIOTIC PARAMETERS ON PLANT SPECIES PERFORMANCE AND THEIR INCLUSION IN SPECIES DISTRIBUTION MODELS
Species have responded to past global changes by shifting their ranges. Ecologists use statistical models, often called niche models, to predict these range shifts. In the process of constructing niche models it is assumed that species distributions can be explained by abiotic (climatic and edaphic) factors alone. That is, the role of biotic processes is ignored. Current practice therefore ignores an important suite of factors that potentially influence species performance and distribution. It could, therefore, be argued that forecasts of future species ranges and associated assessments of future biodiversity distributions are fundamentally flawed.
