Sediments from the Upper Columbia River, Washington, USA, are contaminated with metals from smelting operations. We conducted short-term and long-term tests with the midge Chironomus dilutus and the amphipod Hyalella azteca and short-term tests with
Salmon and steelhead Oncorhynchus spp. have been keystone species for ecosystems and human cultures of the North American Pacific coast for eons. Yet, in the past century, many populations have been greatly diminished and some are now extinct—the r
