Project: The role of wetlands in pelagic food webs: metagenomics reveals how wetland plant detritus may promote zooplankton growth and survival

Description: Funding for this project will be used to identify the best types of restoration in key locations to have maximum impact on supporting the food supply of fish. This study leverages new metagenomics techniques to analyze copepod diets. Recent studies using these techniques showed that wetland vascular plant materials are preferentially consumed by and extend the survival of copepods, a critical food resource presently declining in the Delta. Information generated by this research will be crucial to designing the best possible wetland restoration plans for the Delta.

Reference Number: 3600BQ1996021

Implemented By: Regents of the University of California,. Davis

Objective: Specific objectives are: 1. Quantify the extent to which wetland vascular plant material can support copepod growth 2. Quantify the extent to which wetland vascular plant material can enhance copepod survival 3. Identify sources of plant materials most associated with improved growth and survival 4. Relate the extent to which copepods are supported by wetland vascular plants to the environments from which samples were collected -- a gradient from wetland dominated to pelagic environments
