The development of ABIS has required the cooperation of many people and institutions. The ABIS databases contain specimen label information from Field Museum herbarium collections, current collecting expeditions, and from records captured during visits to numerous herbaria. The curators and staff of the following herbaria are acknowledged: A, BM, CAS, CONC, CPUN, F, GH, HAO, HUT, K, MAK, MA, MO, NY, PRG, SGO, UC, US, USM.

The construction and maintenance of ABIS has been made possible by the following individuals who are acknowledged for their support. They have provided specimens, participated in collecting expeditions, entered data, provided digital information or images, and have helped to develop Field Museum's internet connectivity: J. Cadle, E. Cerrate, M. Chanco, N. Cummings, C. Díaz, D. Dillon, D. Dowdy, R. Dorfman, T. Duncan, M. Ellinger, R. Feldman, R. Ferreyra, S. Hamnik, J. Haas, N. Hensold, G. Jackson, J. Koeppl, K.T. Kong, P. Lowther, G. Montenegro, M. Moseley, N. Munn, M. Muñoz S., M. Nakazawa-Tago, M. Ono, B. Palma, V. Poblete, F. Robinson, P. Rundel, J. Santisteban, S. Teillier, C. Trujillo C., T. Vicari, G. Webster, J. Weinstein, and M. Zapata.

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.

Webpage Design and Development

Activities related to ABIS were aided much by the Museum Informatics Project at the University of California at Berkeley. The MIP staff provided technical support and encouragement in the development of the ABIS home page. Specifically, Tom Duncan [ex-Director of MIP] provided help with the initiation and maintenance of ABIS in the 1990s. In 1994, ABIS was migrated to its current domain.

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. Mr. Zahnle came to the Field Museum as a volunteer in our bar-coding project and during his tenure as a volunteer has helped on diverse projects. His participation on this web site has been instrumental to its design and development.
