Welcome to the mopa wiki!

This is a tutorial containing a full worked example of species distribution modelling using the RSEP method and the three-step methods (TS and TSKM methods) for pseudo-absence generation presented in Iturbide et al., 2015, combining environmental profiling and spatial extent restriction of the background (see Fig. 2 in the cited article). We illustrate the steps followed to produce some of the analyses presented in the article using the R package mopa (MOdelling Pseudo Absences).

NOTE: Most functions presented are implemented in mopa. In the few cases in which functions from other packages are used, the package name is always explicitly indicated.
