We thank Drs. Bruce Patterson and David Willard (Zoology Department, Field Museum) for their kind assistance with the nomenclature of zoological records.
Funding for project field activities has come from several sources. We acknowledge the support of the National Geographic Society Grants entitled: The Botanical Response of Andean Desert Lomas Formations to the 1982-83 El Niño Meteorological Perturbation, Floristic Inventory of the Montane Forests of Northern Peru and Floristic Inventory of the Bosque de Protección del Alto Mayo. The National Science Foundation supported portions of the research on the lomas formations with BSR 8513205: Biogeography and Evolution of the Lomas Formations of Peru and Chile and NSF-SGER Grant: Botanical Collecting and Ecological Observations in Coastal South American Deserts during the 1997-1998 ENSO Event.
Special thanks go to Dr. Helen Beiser for her support and encouragement in the initial phases of implementation.
We wish to thank Paul Zahnle at NuroTec Consulting for the graphic designs presented here and for his encouragement and technical support over the last year.
