      abstract     = {Drylands worldwide are experiencing rapid and extensive
                      environmental change, concomitant with the encroachment of
                      woody vegetation into grasslands. Woody encroachment leads
                      to changes in both the structure and function of dryland
                      ecosystems and has been shown to result in accelerated soil
                      erosion and loss of soil nutrients. Covering $40\%$ of the
                      terrestrial land surface, dryland environments are of global
                      importance, both as a habitat and a soil carbon store.
                      Relationships between environmental change, soil erosion,
                      and the carbon cycle are uncertain. There is a clear need to
                      further our understanding of dryland vegetation change and
                      impacts on carbon dynamics. Here two grass-to-woody ecotones
                      that occur across large areas of the southwestern United
                      States are investigated. This study takes a
                      multidisciplinary approach, combining ecohydrological
                      monitoring of structure and function and a dual-proxy
                      biogeochemical tracing approach using the unique natural
                      biochemical signatures of the vegetation. Results show that
                      following woody encroachment, not only do these drylands
                      lose significantly more soil and organic carbon via erosion
                      but that this includes significant amounts of legacy organic
                      carbon which would previously have been stable under grass
                      cover. Results suggest that these dryland soils may not act
                      as a stable organic carbon pool, following encroachment and
                      that accelerated erosion of carbon, driven by vegetation
                      change, has important implications for carbon dynamics.},
