Our Publications

Initiated in 1997 for Anton Seimon’s doctoral dissertation study at the University of Colorado-Boulder, this field research initiative in the Cordilleras Vilcanota and Carabaya in southern Peru has greatly expanded in scale and scope, and has over the years incorporated a multinational group of scientists. Funding support to cover or offset costs for many of these excursions has been obtained by grants from a variety of sources. These include NASA’s Earth System’s Science division, the Beverly Sears small grants program at the University of Colorado, the National Geographic Society, the National Science Foundation, CIRES at the University of Colorado, The Earth Institute at Columbia University, the Columbia Lamont-Doherty Climate Center, the ALARM consortium of the European Union, and private foundations and donors. Research foci have included regional climatology and climate history from ice core analysis; tropical deglaciation; climate change impacts on alpine ecological systems and highland human populations; surveys of avifauna, mammals and herps; emerging infectious disease of amphibians; soil microbial biology; environmental impacts of road building across ecological corridors; and social and environmental consequences of informal gold mining operations. These efforts have yielded the following scientific publications and media products.
