Nicholas Gotelli and Gary Entsminger's EcoSim. EcoSim is an interactive computer program for null model analysis in community ecology.
EcoSim(version 7.68, updated: July 6, 2004), includes the following null models:

1. Co-Occurrence
2. Macroecology
3. Niche Overlap
4. Size Overlap
5. Species Diversity
6. Standard Tests
7. Guild Structure

EcoSim also computes individual-based rarefaction by the classic combinatorial formula. (EstimateS uses the Coleman curve approximation.)
SAM: Spatial Analysis in Macroecology. SAM, downloadable freeware developed by Thiago Rangel and colleagues, is a compact but robust computer program designed as a package of statistical tools for spatial analysis, mainly for applications in Macroecology and Biogeography. SAM runs under Microsoft Windows as as a user-friendly, menu-driven, graphical interface computational program. SAM offers a wide spectrum of statistical methods currently used in Surface Pattern Spatial Analysis. Sam fills most current scientific and analytical needs of Macroecologists, Biogeographers and Geographical Ecologists who study broad scale biological patterns and processes.

BioDiversity Pro. BioDiversity Pro was designed and developed by Neil McAleece. This package was devised jointly by P.J.D. Lambshead and G.L.J. Paterson of the The Natural History Museum in London and J.D. Gage of the Scottish Association for Marine Science, Oban, Scotland.

Jari Oksanen's VEGAN Package for R. The VEGAN package is intended to help vegetation ecologists and other community ecologists to use R. It contains all major ordination methods, ecologically meaningful dissimilarity indices, tools to analysis of diversity, species richness and abundance models, plus numerous support functions
