Description of The Major Programs in the Cornell Ecology Programs Series

The Cornell Ecology Programs (CEP) were developed under the leadership of the late Dr. Robert H. Whittaker to facilitate the analysis of ecological data. These FORTRAN IV programs were distributed by the department of Ecology and Systematics (E&S) at Cornell to run on mainframe computers.

In 1986, editor Hugh G. Gauch and Dr. Richard E. Furnas arranged with E&S to assure continued distribution of the CEP series.

Mr. Gauch is one of the original authors of the early programs in the series and now works in Cornell's Department of Soil Crop and Atmospheric Sciences. His current work is represented by his program MATMODEL also featured in this catalog.

Dr. Furnas has a Ph.D. in Ecology from Cornell, having taken courses under Dr. Whittaker, teaches during the academic year in the Department of Mathematics at Cornell and is proprietor of Microcomputer Power.

Our agreement to assure continued distribution of the programs has also allowed us to produce microcomputer versions. The more important programs are now available for MS-DOS computers.

The CEP series emphasizes techniques of indirect ordination and classification. Typical input data consists of species abundance information for a number of sites.

Since 1989, we have been happy to offer the program CANOCOTM by Dr. Cajo J.F. ter Braak of the Agricultural Mathematics Group -- DLO at Wageningen in The Netherlands.

CANOCOTM is a major extension of DECORANA (available as part of the CEP series) which allows the incorporation of environmental information directly in the analysis. Dr. ter Braak has done a remarkable service to ecologists. He has developed a sound mathematical foundation for many of the useful but sometimes rather ad-hoc methods which ecologists developed. He has then extended the methods into significant new areas and implemented them in his computer program CANOCOTM.

An important consequence of this more recent research is that CANOCOTM is able to detect relationships between species and external (environmental) variables. These relationships need not be linear, as was required for many of the older techniques, but can be "unimodal", rising and falling again as the optimum environmental conditions for a species are approached and passed. The available data can be explored to isolate the more important environmental factors. CANOCOTM represents a next generation in software for ecological data analysis. Dr. ter Braak is actively developing it, adding new capabilities, refining existing ones, and improving its ease of use.

New to this catalog is CanoDrawTM 3.0, by Petr Smilauer. CanoDrawTM 3.0 makes the output of CANOCOTM accessible in graphic form adding significant exploratory and analytical power to CANOCOTM . Exploring your data has never been so direct.
