Description:

Objective:

The objective of this research project is to determine the efficacy of a suite of molecular-, biochemical-, cellular-, and tissue-level indicators to collectively predict ecosystem responses to contaminant stress. Biomarkers of reproductive impairment are important early-warning indicators of ecosystem impacts, but they need complete characterization and validation in an ecosystem context as proposed in Pacific Estuarine Ecosystem Indicator Research (PEEIR). This section's particular emphasis is on the assessment of reproductive parameters. Because rapid and accurate techniques are not readily available, biomarkers associated with reproductive impairment can be early-warning indicators of stress and reproductive impairment can be directly linked to effects on populations through modeling efforts. The research proposed here is integral to the overall objectives of PEEIR, which are to establish indicators that environmental managers can use to: (1) develop an approach for synthesizing indicators into technically defensible assessments of wetland health and integrity; (2) determine biotic integrity for fish and invertebrate populations within wetland communities; and (3) determine toxicant-induced stress and bioavailability for wetland biota.
