What do I need to model species distribution?

Usually the modelling starts with observing species occurrences and with finding environmental variables that are thought to influence habitat suitability. In any case, conceptual models help to find the main biotic and abiotic factors that control species distribution. Species occurrence … Continue reading

Species Distribution Modelling

To investigate changes at different spatial scales environmental scientists often use statistical models to extrapolate environmental data in space. Species distribution models (SDM), also called ecological niche models or habitat suitability models, utilize relationships between environmental variables and species observations … Continue reading
