PECBO Appendix Site Map

This module is designed for biologists and ecologists interested in analyzing biological data to infer environmental conditions at a site. This module describes different methods for computing biological inferences. Statistical scripts that perform some of the computations described in this module are available for download. Sample data are also available for testing the scripts.

Throughout this module a working knowledge of stream ecology and statistics is assumed.

Navigating the Appendix works best from the Helpful Links box.  Avoid using the back button on your browser.   A link to the PECBO Appendix Site Map is provided on every page and via the left side navigation bar too.
 
The PECBO Appendix is organized into five major sections.  
  1. Introduction
    This section provides definitions and some of the theoretical foundations of taxon-environment relationships and tolerance values.
  2. Using Taxon-Environment Relationships 
    This section provides a step-by-step guide for using existing taxon-environment relationships provided in CADDIS for inferring environmental conditions from biological observations.
  3. Estimating Taxon-Environment Relationships
    This section describes different methods for estimating taxon-environment relationships from your local data.
  4. Computing Inferences
    This section describes different methods for using taxon-environment relationships to infer environmental conditions at a site from biological observations.
  5. R-scripts
    This section provides statistical scripts for performing some of the computations described in this module.
