Abstract:
Data layers producedProbPresence: This dataset contains the predicted probability of presence (Pp) of 15 deep-water shark and rays species in a 1000-hook bottom longline fishing set (type LLA) in the Azores, using a Generalized Additive Models (GAM) approach with binomial distribution and logit link function, through the implementation gam in the package mgcv.

This approach involves using the Probability of presence and the presence-only data to predict species abundances (Pa) (as described in other datasets). The final predicted abundance values (Fpa) were computed by multiplying the Pp by the Pa.
