Software Links
Disclaimer: listing software here does not necessarily imply endorsement. It simply means I have stumbled across the link, or that somebody brought it to my attention. The below include commercial products, experimental products, and range in price from free, to unaffordable. Most links are related to ordination, but some perform other kinds of analysis of interest to community ecologists. Much of the text in the alphabetical list represents direct quotes from the vendors. A special note of caution when doing comparative shopping: without pointing fingers, I suspect that the claims of some of the packages are a little over-blown, and some of them inaccurately represent the products of their competitors. I would be glad to hear of other links, or reports of dead links.
The links are available both alphabetically and sorted by method.
- ADE-4: Exploratory and Euclidean methods in Environmental sciences
- BIOTA: Specimen-Based, Biological Data and Collections Management Software for Individuals, Institutions, and Projects, by Robert K. Colwell
- Brodgar: Software for multivariate analysis and multivariate time series analysis
- CANOCO for Windows: A package for numerous ordination techniques, but with particular strengths in constrained ordination and hypothesis tests.
- CANODRAW: a program written by Petr milauer to graph the results of CANOCO and perform exploratory analyses on ordination results; now defunct because its functionality is tightly integrated with Canoco 5.0
- CAP - Community Analysis Package: a multipurpose package for community data, including classification and ordination
- EstimateS: Software to estimate species diversity by a number of algorithms, by Robert K. Colwell
- Exeter software: A large number of DOS and WINDOWS-based programs for ecology and evolution, including programs for diversity statistics, systematics, resampling statistics, spatial analysis, curve fitting, population dynamics, and more.
- GENSTAT - a comprehensive statistical package that includes generalized linear modelling, principal component analysis, canonical variates analysis, factor rotation, principal coordinate analysis, Procrustes rotation, correspondence analysis, discriminant analysis, hierarchical and nonhierarchical cluster analysis, multidimensional scaling, and biplots
- GS+ for Windows: software for geostatistical mapping (e.g. kriging) and variography.
- Kovach Computing Service: A wide variety of software for ecological data analysis and simulation, including MVSP.
- MEANSIM6 - Free Windows-based software for mean similarity analysis, a method of assessing the strength of a classification of many objects (sites) into a relatively small number of groups.
- MICROCOMPUTER POWER: U.S. Supplier of CANOCO, CANODRAW, and Cornell Ecology Programs.
- Multivariate Software, Inc.: for structural equation modeling and similar analyses
- MVSP: a software package for ordination (many methods) and classification
- NETMUL : for online multivariate data analysis through the internet
- PC-ORD : A program by Bruce McCune for a wide variety of ordination and classification methods.
- PISCES offers software for the analysis of species richness, diversity, population growth, and marine food webs. Direct gradient analysis (RDA and CCA) has recently been added.
- PRIMER: Software from the Plymouth Marine Laboratory, including BIOENV and a variety of ecological analyses
- Rarefaction Calculator: An online web program for rarefaction
- SYN-TAX - a program (DOS and MAC, Windows under development) for PCA, PCoA, CA, NMDS, CCA, RDA, seriation, Procrustes analysis , testing ordination dissimilarities, hierarchical and nonhierarchical clustering, fuzzy clustering, minimum spanning trees, block clustering, comparison of dendrograms, partitions, consensus partitions, simulated sampling and pattern analysis in species assemblages, character ranking, graphic displays.
- Vista- the visual statistics system. For multivariate data display and correspondence analysis, among other things.
Multivariate software, sorted by method
This list was created based on the claims of web documentation, rather than actual experience with each program. Some of the sites are easier to navigate than are others; therefore some of the sites will be more completely and correctly classified below than others.
