The Adélie penguin is a sea-ice obligate species so ocean habitats in the Southern Ocean surrounding Antarctica are crucial during all stages of the species annual cycle.

Implementing the Seed Strategy creates jobs and provides career-building opportunities for students and early career professionals.

The USGS Fire, Invasives, Restoration, and Ecology in Sagebrush Steppe (FIREss Team) plants a common garden of rubber rabbitbrush (Ericameria nauseosa) near Boise, Idaho in collaboration with USFS.

Juvenile Coho salmon (Oncorhynchus kisutch) behavior is assessed following exposure to 6PPD-quinone, a derivative of the compound 6PPD which is used in tires to prevent wear.

The Adélie penguin is a sea-ice obligate species so ocean habitats in the Southern Ocean surrounding Antarctica are crucial during all stages of the species annual cycle.

Due to multiple reasons including the widespread use of microplastics, their environmental persistence, the global connectedness of aquatic environments, and the long-range transport of microplastics, these particles have been documented in every environmental compartment (e.g., air, water, soils).
