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

2
Arguments
current
Raster* objet of present distribution.
Raster has continue values.
project
RasterStack* object of project distributions.
Must have three models with continue values.
thr.value
Cut value (0 — 1) of threshold in order to
species distribution.
continue
defines if the species distribution are either binary or continue maps.
Default = FALSE.
Value
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
