To elaborate our model we removed uncertain localities such as those localities with no coordinates and all records with coordinates laying down in sites with estimated elevations below 878 m and above 2,912 m.
The habitat suitability model generated in Maxent showed extensive areas suitable in climatic terms for this species along the Western and Central Andes and Sierra Nevada de Santa Marta. Except the southern Central Andes, those areas are not known to be occupied by this species and were deleted from our final potential distribution map.
Assuming that the distribution of the species may have filled the complete climatic model generated, its distribution today in remnants of forest is about 28,225 km2, which corresponds to a loss of 52 % of its potential original distribution due to deforestation.
Regularized training gain is 1.905, training AUC is 0.970, unregularized training gain is 2.488.
Algorithm converged after 580 iterations (16 seconds).
The follow settings were used during the run:
20 presence records used for training.
10020 points used to determine the Maxent distribution (background points and presence points).
