Article
Cameron W. Barrows, Auteur ; John T. Rotenberry, Auteur ; Michael F.

Rotenberry, AuteurIn contrast to the body of work in more mesic habitats, few studies have examined boundary processes between natural and anthropogenic desert landscapes. Our research examined processes occurring at boundaries between a desert sand dune communit[...]
