On-Going and Future Research

As detailed throughout these web pages, the dynamic nature of the Pinaleno ecosystem requires frequent monitoring.  These monitoring efforts chronicle fluctuations in squirrel abundance, food availability, vegetation composition, and weather.  In addition, the Red Squirrel Monitoring Program (RSMP) is conducting basic and applied research on various aspects of the Pinaleño ecosystem.  Current and future research projects will examine the impacts of introduced Abert's squirrels (Sciurus aberti) in the mountains and assess the mammalian community associated with the nutrient rich middens characteristic of red squirrels in coniferous forests.  Furthermore, we endeavor to monitor survival, reproductive performance, and space use of the endangered red squirrels at a fine scale by carefully marking and observing squirrels from a distance and via radio telemetry.  These data promise to provide critical insight on the demography and habitat use of Mt. Graham red squirrels in the ever-changing, high elevation forests of the Piñalenos.  Revisit our web page for periodic updates on the status of these projects and to download reprints of research articles as they become available.   Also visit John L. Koprowski's (Director of the RSMP) personal web page for a list of his current graduate students and their project titles.
