BROWNIE	Computes estimates of survival and recovery rates for 2-age class band-recovery data.
CAPQUOTA	Computes expected coefficients of variation of survival and capture probability for use in the design of capture-recapture-resighting experiments.
CAPTURE	Computes estimates of capture probability and population size for "closed" population capture-recapture data.
CENTROID	Tests the null hypothesis that two samples of recoveries belong to the same bivariate distribution.
COMDYN	Computes estimates of species richness using large scale data.
CONTRAST	Compares estimates of survival (or any normally distributed parameter estimates).

• Citations - One of the problems with obtaining software from the Web is that hard copy documentation is not available. The following site provides information on how to cite electronic documents: MLA-Style Citations of Electronic Sources Here is a sample citation for one of the programs:

• The programs are stored as "zip" archives. Most of the zip files contain both the source code (usually FORTRAN) and IBM-PC compatible executable files. If you need an unzipping program, you can download a free Windows unzipper 7-zip or a free MSDOS unzipper [unzip.exe].
• Program SURVIV requires a FORTRAN compiler to generate the user-defined estimation routine. If you do not have one, click here to download the FREE Gnu FORTRAN compiler for WINDOWS 95/NT. Click here to download program SURVIV with the Gnu FORTRAN compiler.
• A good, free ascii text editor (Notepad++) can be downloaded here for more information.
