Occurrences

A dataset containing plant occurrences of five Cryptocarya species
native to New Caledonia. Occurrence data come from the Noumea Herbarium
(NOU) and NC-PIPPN network (see Ibanez et al (2014) in reference below).

datasets

Allows to map species richness and endemism based on stacked
species distribution models (SSDM). Individuals SDMs can be created using a
single or multiple algorithms (ensemble SDMs). For each species, an SDM can
yield a habitat suitability map, a binary map, a between-algorithm variance
map, and can assess variable importance, algorithm accuracy, and between-
algorithm correlation. Methods to stack individual SDMs include summing
individual probabilities and thresholding then summing. Thresholding can be
based on a specific evaluation metric or by drawing repeatedly from a Bernoulli
distribution. The SSDM package also provides a user-friendly interface.
