Plant Ecophysiology

Ecoss studies the interactions of plants with their physical and biotic environments at a fundamental level common to all organisms: gas exchange, energy balance, and water relations. We explore how plants make a living in diverse environments ranging from deserts to rainforests. A longstanding interest is the biophysical and ecological […]

Global change affects plants and soil in ecosystems across the globe. By doing so, it can alter the composition of ecosystems and the functions they provide. For instance, even small changes in plant growth and soil properties can have a large impact on the amount of CO2 and other greenhouse gases in the atmosphere. At Ecoss, we use field experiments to manipulate the temperature, rainfall and other environmental factors in various ecosystems. This allows us to mimic future conditions, and helps us understand how future ecosystems will differ from the ones today. (more…)

An Alaska Army National Guard UH-60 Black Hawk helicopter from 1st Battalion, 207th Aviation Regiment, drops approximately 700 gallons of water from a “Bambi Bucket” on to the Stetson Creek Fire near Cooper Landing, Alaska, June 17. Two AKARNG Black Hawk helicopters flew a total of 200 bucket missions, dumping more than 144,000 gallons of water on the 300-acre Stetson Creek Fire on the Kenai Peninsula.

Measuring the Impact of Severe Fires in the Arctic

Ecoss researcher Michelle Mack is leading a $1 million NASA-funded project to measure the extreme fire activity in boreal forests and its effects on arctic tundra. Based on the number of acres burned, 2015 is shaping up to be the second most extreme fire year during the past decade in North […]

Human Microbiome

Ecoss studies the microbial communities of the human body and the implications for disease including STDs and HIV, as well as analyzing the microbial community using bioinformatics, community ecology theory and Bayesian statistical modeling.
