Ecosystems develop and change through interactions between living things and their physical environment. A shift in vegetation is one of the most important changes an ecosystem can experience, because it can alter exchanges of energy (originating from sunlight), water, and elements such as carbon (C) and nitrogen (N) between air, plants, and soil. In the Arctic, a widespread shift from tundra to deciduous shrub-dominated vegetation appears to be occurring.

This project will assess contributions of different shrub feedbacks to carbon and nitrogen cycling, and improve predictions of the consequences of shrub expansion in the Arctic for regional and global climate.

The research team was based out of Toolik Field Station, an 8-10 hour drive north from Fairbanks, Alaska. Toolik Field Station is operated by the Institute of Arctic Biology at the University of Alaska Fairbanks and has hosted hundreds of researchers and students every year since 1975. The team will drive to an additional field site ninety miles north of Toolik Field Station.

A week ago I drove away from Toolik, down the Dalton Highway, back to Fairbanks and eventually traveled back home. My co-pilot slept almost the entire time so I had 8.5 hours to reflect on the expedition while navigating the often one lane dirt road that winds around mountains and has potholes the…
Just because the pluck is over doesn't mean that there isn't work to do! On Saturday we headed to the Sagwon site 90 miles North of Toolik. Driving on the Dalton Highway is always an experience and sort of like the old video game Frogger where instead of dodging cars, we dodge potholes. After…
What an incredible few weeks I have had! The pluck ended earlier this week after eight days of carefully removing plants from earth. Eight days and fourteen people sitting around a table working from 9:00 am to at least 5:00 pm, if not later. The plants were then put in one of six scientific ovens…
Plucking is hard work! It requires attention to detail and long hours. Today is day eight of the work. We have worked nonstop since last Monday, somedays even until 10:30-11:00 at night. Plant identification is harder if the plants are dried out, so once we start a quadrat, it has to be finished…
