# Title of Dataset: --- Unraveling the cavity-nesting network at large spatial scales: the biogeographic role of woodpeckers as ecosystem engineers ## Description of the Data and file structure The spatial database that was used to model the cavity-nesting network in southern South America. Each variable was used in SEM analysis Response variables used in this analysis are: USERS_TOT= richness of all cavity users; USERS_O= richness of obligated cavity users; USERS_G= richness of generalist cavity users; USERS_FS USERS_MAM= richness of mammal cavity users. ## Sharing/access Information Data was not derived from another source.
