bamm - Species Distribution Models as a Function of Biotic, Abiotic and
Movement Factors (BAM)
Species Distribution Modeling (SDM) is a practical
methodology that aims to estimate the area of distribution of a
species. However, most of the work has focused on estimating
static expressions of the correlation between environmental
variables. The outputs of correlative species distribution
models can be interpreted as maps of the suitable environment
for a species but not generally as maps of its actual
distribution. Soberón and Peterson (2005)
<doi:10.17161/bi.v2i0.4> presented the BAM scheme, a heuristic
framework that states that the occupied area of a species
occurs on sites that have been accessible through dispersal (M)
and have both favorable biotic (B) and abiotic conditions (A).
The 'bamm' package implements classes and functions to operate
on each element of the BAM and by using a cellular automata
model where the occupied area of a species at time t is
estimated by the multiplication of three binary matrices: one
matrix represents movements (M), another abiotic -niche-
tolerances (A), and a third, biotic interactions (B). The
theoretical background of the package can be found in Soberón
and Osorio-Olvera (2023) <doi:10.1111/jbi.14587>.
