Takes raster layers and occurence data and fits the broennimann niche similarity, equivalency and overlap models. This is simply a wrapper to functions in the R package ecospat (https://cran.r-project.org/web/packages/ecospat/index.html)
1 2 | broennimannEcospat(native_stack, invasive_stack, native_occ, invasive_occ,
kept_axes = 2)
|
native_stack |
A raster stack of the environmental data for the range of the native species. |
invasive_stack |
A raster stack of the environmental data for the range being invaded |
kept_axes |
The nf parameter in the function dudi.pca - is the number of kept axes - defaults to 2. |
natice_occ |
Occurence points for the native species (i.e. where the species that will be invading into the invasive range is in it's native range). A two-column matrix with column headings x and y (corresponding to longitude and lattitude) |
invasice_occ |
Occurence points for the species in the invasive range (either the invading species in it's invasive range, OR the species that might compete with the invader).A two-column matrix with column headings x and y (corresponding to longitude and lattitude) |
