sabinaNSDM: An R package for spatially nested hierarchical species distribution modelling
Methods in Ecology and Evolution, Volume 15, Issue 10, Page 1796-1803, October 2024.Abstract Species distribution models have evolved to combine species‐environment interactions across multiple scales. Spatially nested hierarchical models (NSDMs) offer a promising avenue by integrating datasets and predictive models from broad to fine scales. But a user‐friendly tool to execute these models remains an important ongoing challenge.
