Resumen:
Ecological Niche Modeling uses the geographic coordinates of species
presence records as the primary input to estimate potential geographic
distributions. It is little known whether carrying out rigorous data
pre-processing is necessary before building niche models to be
transferred to different time period. Here we compared the current,
past, and future potential distributions projected by niche models built
from two different databases, an open-access database and a database
compiled ad hoc, for Handleyomys chapmani, a rodent closely associated
with montane cloud forests in Mexico. The models predicted different
spatial patterns of climatic suitability for the three periods examined.
Based on our current knowledge of cloud forest species in Mexico, the
distributions predicted by the model built from the ad hoc database are
more ecologically realistic than those obtained from the open-access
database. The models built using the open-access database were
particularly inaccurate at the limits of the geographic range,
predicting larger, more diffuse distributions for the three periods. We
conclude that pre-processing occurrence data is crucial for mountain
species, as the number of localities and even minor inaccuracies in the
geographic coordinates can translate into very different climatic
conditions due to abrupt altitudinal changes. Finally, the predicted
shifts in the potential distribution of H. chapmani over time indicate
that this species is highly susceptible to climate change.
