Spatial and Temporal Assessment of Vertically Migrating Myctophids as Biotransporters of Microplastics to Mesopelagic Food Webs

Creator:

Boisen, Olivia C.

Abstract:

It is well documented that microplastics and semi-synthetic particles (<5 mm) pervade the marine environment, with their ingestion by marine fauna eliciting global concern. While fishes exposed to microparticles in a laboratory setting have exhibited both sub-lethal and lethal effects, the diversity in material, morphology, and size of these contaminants...

Hold the Plastic, Please: An Investigation of Sea Otter Exposure to Microparticles and Microplastics Using Scat and Diet Analysis

Creator:

Van Brocklin, Jennifer E.

Abstract:

Sea otters act as valuable indicators of ecosystem health and consume prey items that contain anthropogenic microparticles, including microplastics. Microplastic ingestion can exert a wide range of deleterious effects depending on the organism and plastic type. We investigated the ingestion of microparticles by wild sea otters (Enhydra lutris) in Alaska...

Identifying Environmentally Relevant Abundances and Characteristics of Internalized Microplastics in Northern California Current Zooplankton

Creator:

Bolm, Anna E.

Abstract:

Microplastics are ubiquitous in our oceans, yet we are still clarifying what risks they pose to marine organisms, which can be challenging due to their trait diversity and spatial patchiness. Laboratory-based studies assessing risk demonstrate that many marine animals internalize microplastics, either actively through ingestion or passively via respiration. However,...
