Organic energy budget of Rattlesnake Springs, Washington
Calculation of organic energy budgets has become a widely used method to compare lotic ecosystems and ecosystem functioning. Fisher and Likens included import and export of particulate organic matter (POM) with the parameters of production (P) and respiration (R), providing stream ecologists an added refinement in characterizing the trophic basis of streams. An annual organic energy budget for Rattlesnake Springs showed the system to be autotrophic as measured by the P/R ratio (P/R = 1.38). In terms of detrital processing, however, the system was a net importer on an annual basis despite one major export (remissive) event. Suggestions are made concerning the expression and comparison of annual stream energy budgets.
