Abstract: We address the problem of how to estimate a hypothetical fundamental niche from presence data. We do this by: a) postulating a simple shape for the physiologically defined niche (Hutchinson’s fundamental niche), b) providing prior information for the estimation of the parameters that define the shape of the niche, and c) interpreting the results taking into account how the actual observables are conditioned on the existing environmental universe. We provide a probabilistic (i.e. Bayesian) statement of the problem and the posterior distribution for estimating the parameters of fundamental niches, as well as software to perform the estimations.
