Agroborealis is the research publication of the Agricultural and Forestry Experiment Station and the School of Natural Resources and Extension. It describes research in the areas of agriculture, soils, forest sciences, natural resources, and economic and community resilience. The research magazine, which was founded in 1969, is available now in a new format. Easily downloadable research stories — at least two Agroborealis research highlights twice a year — will be published spring and fall.
Links to the stories will be emailed when they are posted on this site. If you’d like to be added to the email list, please subscribe here.

Meriam Karlsson’s research focuses on greenhouse and controlled environment crop production and resource management in commercial greenhouses.
The University of Alaska Fairbanks horticulture professor has studied a diverse array of flowers and vegetables to see under what conditions they grow best. Because of the current interest in food crops, much of her work concerns greenhouse food production.
Her office is a few steps down the hall from the greenhouse where she conducts her research, on the south side of the Arctic Health Research Building.
Cucumbers and tomatoes grow successfully in Alaska greenhouses, and Karlsson believes that bell peppers could be another potential commercial crop. For the past three years, she has researched the best methods for growing them. To optimize greenhouse space and productivity, the plants are commonly trellised, with two lateral branches. Karlsson looked at how pruning the lateral branches affected the production on six cultivars of red, orange and yellow peppers.
Studying Dall sheep habitat
University of Alaska Fairbanks Professor Dave Verbyla is working with a team of scientists to find out why Dall sheep populations in some areas have declined by more than 20 percent rangewide since 1990.
The decline was most pronounced in the western Brooks Range, where the population has dropped 70 percent. Declining populations have led to emergency harvest closures and a contentious wildlife management issue for sport and subsistence hunters.
Verbyla is participating in a four-year study funded by NASA that will look at the changing habitat of Dall sheep in Alaska, the Northwest Territories, northern British Columbia and the Yukon Territory. The study will consider how vegetation and snow conditions are changing in alpine ecosystems and how those changes may affect Dall sheep.
