Records of occurrence for Ochotona alpina (n=16)

Model outputs

Here we are NOT aiming to model the actual observed range of the species, but the extent of the potentially suitable bioclimatic envelope. This will inevitably be larger than the actual range as it is not restricted by landcover or anthropogenic impacts etc. However, the potentially suitable bioclimatic envelopes have now been clipped so that unsuitable habitat (based on land cover classes) is omitted. The areas in black represent suitable climate and habitat and the areas in blue represent only suitable climate.

Your expert opinion is extremely useful in evaluating these models and will lead to us assessing Maxent as a platform for species distribution modelling. We ask that you provide your expert opinion of the models, rather than an evaluation of our success at modelling the species; a negative evaluation is just as informative as a positive one.
