Ecosystem Analysis Program

The Ecosystem Analysis Program uses state-of-the-art methods to provide information and tools to manage and conserve aquatic species and their associated ecosystems. Our research encompasses populations, communities, and ecosystems and integrates a variety of disciplines including ecology, physiology, and statistics. Our goals are to:

Identify patterns and processes

We combine field sampling and mathematical analysis in seeking to understand how factors such as species interaction, climate change, and land use affect the patterns we observe among various ecosystem components.

Conserving thermal habitat for Pacific salmon

Climate impacts to Pacific salmon

Develop scientific tools

We design, construct, and evaluate new techniques and equipment for studying animals in aquatic environments ranging from small streams to the ocean. We track animals using radio telemetry, passive integrated transponder (PIT) and acoustic tags with remote antenna systems for detection. We also develop quantitative methods and software for both retrospective and prospective analyses of ecosystem attributes such as food web interactions, survival, and migration rates.
