Welcome to the Population Analysis Software Group
This site is used for the distribution of software for the analysis
of fish and wildlife populations using marking and sighting methods. Most
of the software was developed by Neil
Arnason at the University of Manitoba
and Carl
Schwarz at Simon Fraser University.
This site is organized as a hierarchy. The menu bar on the left lets you go to the major sections. When you go to a section, the menu bar will show you the subsections (if any), and give you an "up one level" to return to the main section menubar. A "you are here" on the upper right corner tells you where you are in the hierarchy. There is a site history below that lets you see when and where major changes and additions were made to the site.
The main sections are:
- The Popan5 section describes the POPAN program for the analysis of open population, mark-recapture data. This section describes what POPAN can do and how to download and install the program and obtain its manuals.
- The Popan6 section describes development of the new POPAN-6 version, including a test version you can try out now. This section is for readers already familiar with POPAN-5.
- The SPAS section gives descriptions, manual and download instructions for the Stratified Population Analysis Program for estimating abundance using mark and single recapture models in stratified populations.
- From the Other Software section, you can do the same for other programs that analyse stratified population data (SMOLT) and a program (EAGLES) for estimating numbers of animals from sighting data.
- X-Change takes you to the HyperNews forum where population estimation issues are discussed. The forum is managed by Evan Cooch (Cornell University) for users of the major mark-recapture analysis programs (Mark, Surge, Surph, Popan).
- The Publications section gives you access to online (pdf) versions of the research papers directly related to the software on this site.
- Links provides links to some other sites concerned with population estimation methods and software.
