1. Microplastics in beluga whale (Delphinapterus leucas) prey: an exploratory assessment of trophic transfer in the Beaufort Sea.

Microplastics (MPs, <5 mm in length) have been identified as emerging contaminants in marine environments, with ingestion by a variety of biota being of increasing concern. Few studies exist on MP ingestion in Arctic fish, and there are currently no such data from the Beaufort Sea. We...

2. A cross-species comparative approach to assessing multi- and transgenerational effects of endocrine disrupting chemicals.

A wide range of chemicals have been identified as endocrine disrupting chemicals (EDCs) in vertebrate species. Most studies of EDCs have focused on exposure of both male and female adults to these chemicals; however, there is clear evidence that EDCs have dramatic effects when mature or developing...
