Hi, the recent edit you made to Trophic dynamics has been reverted, as it appears to be unconstructive. Use the sandbox for testing; if you believe the edit was constructive, ensure that you provide an informative edit summary. You may also wish to read the introduction to editing. Thanks. treelo talk 23:53, 5 May 2008 (UTC)
