RAPIDLY SHIFTING WATERSCAPES IN THE TROPICAL HIGH ANDES OF SOUTHERN PERU
The Cordillera Vilcanota, southern Peru, has been the focus of more than a decade of research to understand biological and societal impacts of rapid climate change. Tropical high-elevation aquatic ecosystems face uncertainty surrounding the onset and duration of the wet season. Simultaneously, rapid deglaciation alters alpine habitat states and extents. We synthesized participatory observation of daily pastoral practices in a high-elevation herding community with reproductive phenology surveys of a high-elevation amphibian community to examine responses to delayed wet season onset during the 2015/2016 El Niño. We identify parallel key strategies (i.e., flexible mobility¬—humans; reproductive plasticity—amphibians) for confronting unpredictable, extreme conditions in rapidly changing high-mountain environments. We analyzed stable isotope signatures to identify threatened aquatic habitats fed by glaciers, long-term observations of wetland vegetation cover, and interviews with local herders regarding past, current, and future wetland availability. Future reductions to connectivity between aquatic habitat and glacial meltwater may decrease the availability of suitable habitat for aquatic organisms and wetland grazing areas for alpaca herds, the principal economic resource in this pastoralist community. Our results suggest that pasture management may provide crucial local aquatic refugia under climate change.
