spat.alpha.vec

Alpha and beta diversity for taxonomic (TD), functional (FD),
and phylogenetic (PD) dimensions based on rasters. Spatial and
temporal beta diversity can be partitioned into replacement and
richness difference components. It also calculates standardized effect
size for FD and PD alpha diversity and the average individual traits
across multilayer rasters. The layers of the raster represent species,
while the cells represent communities. Methods details can be found at
Cardoso et al. 2022 <https://CRAN.R-project.org/package=BAT> and
Heming et al. 2023 <https://CRAN.R-project.org/package=SESraster>.
