Files for null model analysis
Note: intended for educational use.

These matrices were compiled under NSF grant BSR 9106981 awarded to Bruce Patterson in 1991. The grant supported a collaboration of Wirt Atmar, Alan Cutler, Gregory Mikkelson, Bruce Patterson, and David Wright. The original matrices and notes concerning their derivation were downloaded from AICS Research INC.

Recommended citation format: ''Atmar, J.W., and B.D. Patterson. 1995. The nestedness temperature calculator: a visual basic program, including 294 presence-absence matrices. AICS Research, Inc., University Park, NM, and The Field Museum, Chicago.''

Disclaimer: In the files linked below, I have removed the notes and citations, and transposed the data. While I have not intentionally modified the data in any other way, neither have I gone back to the original publications to confirm accuracy.

The data matrices can be copied into any simple text editor (such as Notepad) and saved as .txt files. The resulting file can be opened directly from Ecosim. The file names in the last column refer to the names used by Atmar et al in their original work.

Data extracted from http://academics.smcvt.edu/dmccabe/teaching/Community/NullModelData.html ; Files lacking a hot link are missing from McCabe's Web site and have been placed here from files provided by Bruce Patterson to Declan McCabe in 2015.
