Javan was born and raised in the Pacific Northwest (Washington and Idaho) and received his M.S. from Idaho State University where he studied the movement and habitat ecology of prairie rattlesnakes. He then worked for non-profit reptile conservation organization, The Orianne Society, conducting and directing research projects to guide reptile conservation efforts.

I completed a B.S. in Wildlife and Fisheries Conservation at the University of Massachusetts in Amherst in 2004, a M.S. in Biology at Purdue at Fort Wayne in 2008, and a PhD in Natural Resources at University of Illinois in 2014.

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.
