| Species distribution modelling is central to both fundamental and applied
research in biogeography. Despite widespread use of models, there are still
important conceptual ambiguities as well as biotic and algorithmic uncertainties
that need to be investigated in order to increase confidence in model results. We
identify and discuss five areas of enquiry that are of high importance for species
distribution modelling: (1) clarification of the niche concept; (2) improved
designs for sampling data for building models; (3) improved parameterization;
(4) improved model selection and predictor contribution; and (5) improved
model evaluation. The challenges discussed in this essay do not preclude the need
for developments of other areas of research in this field. However, they are critical
for allowing the science of species distribution modelling to move forward. | |
