Topaza pyra


The habitat suitability model generated in Maxent showed areas that might be possibly occupied by this species west of the Andes, particularly in the pacific lowlands. However, we do know this species is distributed only east of the Andes and excluded those areas from the potential distribution map of the species.

There is one record from DatAves from Santander that clearly is corrupted information and it was excluded to conduct the modelling.

Assuming that the distribution of the species may have filled the complete climatic model generated, its distribution today in remnants of forest is about 338,057 km2, which corresponds to a loss of 8 % of its potential original distribution due to deforestation.


Regularized training gain is 0.274, training AUC is 0.795, unregularized training gain is 0.432.
