Korena Mafune, who earned her master’s last spring working with Professors Dan and Kristiina Vogt, has continued on at SEFS this year with her doctoral studies. Her project involves researching plant-fungal relationships in Washington’s temperate old-growth rain forests, with a specific focus on canopy soils and host tree fungal interactions. Her main goal is to learn which fungal species are associating with the host plant’s adventitious roots in canopy soils, and also to collect any fruiting mushrooms.

“The temperate old-growth rain forests we work in are rare and unique,” she says. “If we disregard the interactions going on in the canopies, we have an incomplete understanding of how these ecosystems function.”
The results from her master’s thesis laid a strong foundation for additional exploration, and Korena just received two grants to support her doctoral research—one for $9,300 from the Daniel E. Stuntz Memorial Foundation, and the other for $1,900 from the Puget Sound Mycological Society.
“With the support of these grants, we are ready to hit the ground running!”
Nice work, Korena, and good luck!

Sandercock stream sampling with her helper Josie.
As part of a delightful deluge of defenses today, the first of three comes at 1 p.m. in Anderson 107 when Maria Sandercock gives the public portion of her Master’s Defense, “The Role of Patterns of Urban Development on Stream Benthic Index of Biotic Integrity Scores.”
Sandercock’s committee includes SEFS Professors Daniel Vogt and Susan Bolton, along with Marina Alberti.
Come out and support Sandercock, and get excited for an afternoon of graduate student excellence!

One of the red-legged frogs Grand found in the field.
This coming Tuesday, May 28, fresh off the holiday weekend, you should leap at the chance to hear Lauren Grand give the public defense of her Master’s Thesis, “Identification of Habitat Controls on Amphibian Populations: The Northern Red-Legged Frog in the Pacific Northwest.”
Join Grand, her committee chair Kristiina Vogt, and committee members Daniel Vogt and Marc Hayes to discuss Rana auroa‘s population controls and habitat needs in an urbanizing landscape.
Her talk begins at 8:30 a.m. in Anderson 22. Refreshments will be served, so come with a hungry tummy!

Miller and one of his Douglas-fir seedlings.
This Thursday, May 23, at 10 a.m. in Winkenwerder 107, Colton Miller will be defending his Master’s Thesis: “Reforesting Surface Coal-Mined Land Using Douglas-fir Seedlings in Washington State.”
Land productivity can be substantially degraded by surface mining, which introduces such problems as erosion, landslides, floods and loss of habitat. Previous research has focused on methods for improving tree seedling establishment on surface mines in the Appalachian region. Miller’s research investigated modified treatments for improving seedling performance in the Pacific Northwest. He also quantified the response of seedling foliar nutrients to post-planting fertilization.
While you let these thoughts take root, go ahead and mark your calendar and come out and join Miller’s committee chair Darlene Zabowski and other committee members Rob Harrison, Eric Turnblom and Dan Vogt!
Refreshments will be served!

Next week on Thursday, May 9, round up your friends and colleagues to come support Erika Knight as she defends her Master’s Thesis! Her talk begins at 1 p.m. in Anderson 22, so join us in commemorating her years of work and research at SEFS.
One of Knight’s treatment plots at the Fall River Long-term Soil Productivity study site in western Washington.
Increasing demand for timber, as well as current interest in the use of woody biomass for energy and chemical production, may result in higher quantities of organic matter removed from plantation forests than currently occurs during harvesting. Knight’s thesis focuses on the potential of two practices that can increase the yield of woody biomass from a harvest site to change soil carbon and nitrogen storage:
1. Application of herbicides to control competing vegetation and improve crop tree growth; and
2. Removal of branches and foliage (slash) in addition to the bole during harvest.
She conducted her research in a 12-year-old Douglas-fir plantation at the Fall River Long-term Soil Productivity site in western Washington. She is part of Professor Rob Harrison’s soils lab, and her other committee members are Professors Darlene Zabowski and Dan Vogt.
