Recently, Warren [1] argued that correlative modelling of species distribution and environmental data should be described as Ecological Niche Modelling (ENM) rather than Species Distribution Modelling (SDM). Although discussions of terminology could be posed as semantics and nit-picking, they are symptomatic of deeper challenges to robustly define the philosophy, methodology, and theory of this science. Terminology should standardise definitions and facilitate understanding and communication, while enabling synthesis and innovation.
