Effects of increased snow on growth response and allocation patterns of arctic plants

Poster Number:  368 Presenter/Primary Author:  Claire Addis Warming in the Arctic has led to an increase in shrub cover on the tundra and has been well documented in arctic Alaska.

Quantifying the physiology of structurally complex arctic vegetation and implications for ecosystem function in a shrubbier tundra

Poster Number:  358 Presenter/Primary Author:  Adam Formica As conditions become more favorable in some arctic regions for shrub growth, shrubs will not only expand laterally, but they will grow thicker and taller, altering the physical structure of the can

The relationships between SOM quality and decomposition across a gradient of increasing shrub abundance in the Alaskan Arctic

Poster Number:  325 Presenter/Primary Author:  Jennie DeMarco Warming arctic temperatures are shifting dominant vegetation from graminoids to deciduous shrubs whose functional traits can alter the quality of soil organic matter (SOM) via litter inputs and roo

The Chemical Properties of Alaskan Permafrost and Seasonally Thawed Soils

Poster Number:  297 Presenter/Primary Author:  Jessica Ernakovich Although permafrost soils contain vast stores of carbon, we know relatively little about the chemical composition of the carbon stored in these soils.
