[R-sig-eco] Error in Maxent maps

[Irene Rojo]

Dear all,

My name is Irene and I am performing Maxent SDM in R with the dismo
package.

I am working with several species, performing one analysis for each
species, and all are working fine, i.e. the models have sense, except two
of them. For those species, I can run Maxent models and I get a very high
value of AUC (0.99) but the resulting maps show values between 0 and 0.005,
when for the rest of the species they are between 0 and (almost) 1. So maps
have no sense. The predictor variables are the same, and those two species
are not the ones with the lowest number of occurrences (this is the first
reason I thought that could be affecting the results).

I know it is not easy to know what is going on, but I am doing exactly the
same with all species. If anyone can guess the error or know which part of
the analysis is more sensitive so I can check it again I would be very
grateful.

Thanks a lot in advance,

Irene
