CALS student research shared at UW Arboretum Science Day – Feb. 15

The CALS community is invited to join the UW Arboretum at their annual Science Day on Thursday, Feb. 15 from 9 to 11:30 a.m. The event features UW student research done at the Arboretum, shared via posters and presentations, with the goal of helping Arboretum staff better understand and manage Arboretum natural resources. The event is free and open to the public.

Several of the presentations and posters will feature CALS students:

Talk: The phenology of snow
Kim Thompson, Department of Forest and Wildlife Ecology

Understanding the phenology of the subnivial refuge—the timing of its establishment, maintenance, and disintegration—is important for characterizing the current conditions to which species are exposed and for predicting future exposure.

Talk: Lessons in integrated tick management
Jordan Mandli, Department of Entomology, and Scott Larson, Midwest Center of Excellence for Vector-borne Disease

Observations from four years of studying landscape manipulation and host-targeted acaricides as possible treatment for reducing tick density and potential Lyme disease transmission.

Poster: Uncovering the secret life of the Amynthas earthworm cocoon
Marie Johnston, Department of Soil Science

This research looks at jumping worm cocoon abundance when reared in the laboratory, and testing temperature tolerance of cocoons to learn about potential control methods.

Poster: Impact of Asian jumping worms (Amynthas spp.) on soil aggregate size and stability
Marie Johnston, Department of Soil Science

Jumping worms change the aggregate structure of the ground surface with visible granularity. We investigated the rate at which these different species affect soil aggregate size and water stability over time and in relation to each other.
