Finding a replacement for 6PPD in tires is one major challenge; another is to prevent the highly toxic derivative 6PPD-Q from reaching salmon streams and killing fish.
Research that began in Puget Sound has revealed much about the cellular-level assault on vulnerable salmon and trout, yet the puzzle remains incomplete.
Longfellow Creek near West Seattle's industrial district still draws spawning salmon despite a century of city development and an onslaught of toxic chemicals. A current exhibit by photographer Tom Reese explores this often-overlooked gem of urban nature.
An estimated 80% of all the salmon in the North Pacific are pink salmon. Scientists say the extreme abundance of pinks could be causing a "trophic cascade" that is harming species across the food web.
All across the region, communities are finding that rising seas and rising rivers are two sides of the same coin. New research funded by the Environmental Protection Agency may help managers target their responses to climate-fueled flood risks in Puget Sound. The following article was commissioned by the Habitat Strategic Initiative Lead (HSIL), a cross-agency team co-led by the Washington Departments of Fish and Wildlife and Natural Resources.
Zooplankton are critical to the marine food web, but until recently there have been few surveys of the zooplankton community in Puget Sound. Ongoing monitoring is now revealing a system full of complexity and surprises. The following article was commissioned by the Habitat Strategic Initiative Lead (HSIL), a cross-agency team co-led by the Washington Departments of Fish and Wildlife and Natural Resources.
Beavers provide critical benefits for wetland ecosystems but can also alter the landscape in ways that are unpredictable for property owners and conservationists alike. New techniques are helping humans and beavers share the landscape with the goal of benefiting both parties. The following article was commissioned by the Habitat Strategic Initiative Lead (HSIL), a cross-agency team co-led by the Washington Departments of Fish and Wildlife and Natural Resources.
Puzzling encounters between endangered killer whales and harbor porpoises point to questions about prey availability and whale culture, scientists say. Are the whales playing, practicing their hunting skills, or is something else going on?
A new strain of avian flu has been sweeping the globe since 2020, leaving thousands of dead seabirds in its wake. This past summer, it arrived at a colony of Caspian terns at Rat Island in the Salish Sea, with catastrophic results.
Salmon restoration groups are learning how to work with beavers to create better salmon habitat. The process hinges on reducing human-beaver conflicts while taking a natural approach to ecosystem recovery. The beavers are happy to help.
