stability: Stability of ecological niche models

Description Usage Arguments Value References


Returns stability niche based on species distribution models and their projections.


stability(current = NULL, project = NULL, thr.value,
  continue = FALSE)



Raster* objet of present distribution. Raster has continue values.


RasterStack* object of project distributions. Must have three models with continue values.


Cut value (0 — 1) of threshold in order to species distribution.


defines if the species distribution are either binary or continue maps. Default = FALSE.


An object of class 'StabEcodist'

Based on binary maps

Return table with these features: Models and nPixel (frequency of pixel with that feature).

Stability maps based on binary species distirbution, give:

Values of 0 Shows absence

Values of 100 Mentions the lost area

Values [1:100] Shows colonizable area. Different models are defined as numbers (e.g. Value of 1 indicates one models predict gain; Value of 2 indicates two models predict agains)

Values > 100 Shows stability or permanence. Differente models are defined as numbers (e.g. value of 101 mentions one model predict stability, value of 102 mentions two models predict stability)

Based on continue maps

Species distribution show different values of stability along of their distributions.

Values of -2 Shows absence

Values [-1 : 0] Shows colonized grade or gain.

Values [0 : 1] Shows stability or permanence

Values of 2 Shows lost area
