Microsoft Access® Users

One search form, built into the database, allows users to search for all data by species, parameter, and location, then allows users to view and print the parameter values and citations to a file. This file can be printed as text or downloaded to other applications (Microsoft Excel®). The data also can be accessed as a series of text files that can be used with a variety of applications. Advanced Microsoft Access® users may wish to forgo the search form and create their own queries on the database by using Microsoft Access® query tools.

Ecophysiological Parameterization Database (804 Kb)

Text or Other Database Users

Seven comma-delimited text files allow researchers who are using software other than Microsoft Access® to use the database. These files are entitled:
• Parameters.txt—includes a list of parameters and definitions
• Parameter-Location.txt—links parameters with locations
• Parameter-Species.txt—links parameters with species
• ParameterValues.txt—includes parameter values, species, site, and reference
information (this is the critical table)
• References.txt—includes the list of references for the parameter values
• Species.txt—defines the species, scientific name, four-letter acronym, and
common name for all species included
• Location.txt—defines the abbreviation for place names used in
ParameterValues
