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...

Using Spatial Capture-Recapture to Estimate Density of Roosevelt Elk in Western Oregon

Creator:

Nelson, Jennifer E.

Abstract:

Spatial capture-recapture (SCR) is employed for estimating abundance and density of species, particularly those that are cryptic or solitary, and evaluating how population density varies with habitat. However, it is uncertain whether estimates are biased when applied to species that aggregate, such as elk (Cervus canadensis). Wildlife managers in the...
