Software:

Stratistics:  A toolkit for spatial statistics in earth sciences and ecology.  An executable copy is available on request.
TraceFossil:  An individual based movement model to simulate foraging in heterogeneous enviroments.  This program is under continuous development, I will place a current version here.    For more information see Plotnick and Koy (2005).  A user's guide is under development.
CAPS : TraceFossil is based on the CAPS, a spatially explicit neutral model for community development (Plotnick and Gardner 2002), developed in conjunction with  Robert Gardner of the University of Maryland Center for Environmental Sciences.  The current version of CAPS can be downloaded from: http://www.al.umces.edu/CAPS.htm
