Abstract:

Estimation of the dimensions of fundamental ecological niches of species to predict their geographic distributions is increasingly being attempted in systematics, ecology, conservation, public health, etc. This technique is often (of necessity) based on data comprising records of presences only. In recent years, modeling approaches have been devised to estimate these interrelated expressions of a species’ ecology, distributional biology, and evolutionary history; nevertheless, a formal basis in ecological and evolutionary theory has largely been lacking. In this paper, the authors outline such a formal basis to clarify the suite of techniques that can be termed ‘ecological niche monitoring,’ analyze example situations that can be modeled using these techniques, and clarify the interpretation of results.
