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.

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).

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.

At the heart of Wisconsin’s rich fishing culture is the walleye – a legendary fish with big, pearly, reflective eyes. In Ojibwe, the fish is called “ogaa" and symbolizes knowledge, illumination, and guidance. Their unique eyes guide them through cool, dark, murky waters, making them formidable predators and a challenging catch for anglers.
