Microtopography Determines How CO2 and CH4 Exchanges Respond to Temperature and Precipitation at an Arctic Polygonal Tundra Site

Microtopography in polygonal tundra affects CO2 and CH4 emissions, but landscape scaling of polygon types accurately captures landscape-scale states and exchanges with the atmosphere.

NGEE Arctic Scientist Writes about Career, Mentoring, and the Value of Good Colleagues

Raised amidst the cornfields and grasslands of Mid-America, this NGEE Arctic researcher has passion and curiosity for people and the plant sciences.

NGEE Arctic Scientists Co-organize Symposium on Trait Covariation

Scientists around the world are working to simplify the vast array of plant species and forms in order to distill general features of plant function, structure, and strategy.

Plant Traits Across an Arctic Landscape: Above versus Belowground

NGEE Arctic researchers are quantifying above and belowground variation in plant functional traits across environmental gradients to inform the representation of plant traits in terrestrial biosphere models.

Evapotranspiration across Plant Types and Geomorphological Units in Polygonal Arctic Tundra

A field research showed that evapotranspiration from mosses and open water was twice as high as that from lichens and bare ground, and that microtopographic variations in polygonal tundra explained most of this and other spatial variation

Controls on Fine-Scale Spatial and Temporal Variability of Plant Available Inorganic Nitrogen in a Polygonal Tundra Landscape

NGEE Arctic researchers documented strong relationship between soil moisture, inorganic N availability, and plant N content across the polygonal ground of the Barrow Environmental Observatory

Reduced Arctic Tundra Productivity Linked with Landform and Climate Change Interactions

Scientists working on the NGEE Arctic project provide evidence linking decadal patterns in arctic greening and browning with regional climate change and local permafrost-driven landscape heterogeneity, using newly developed decade time-scale remote

California’s Governor Jerry Brown Learns About Climate Change Science in Nome

NGEE Arctic scientists from the University of Alaska Fairbanks and Lawrence Berkeley National Lab gave an overland tour of the Seward Peninsula to California’s Governor Jerry Brown to share hands-on climate change research in the Arctic.

PEcAn integration of dvm-dos-tem for uncertainty quantification and variance decomposition

We successfully integrated the Dynamic Vegetation, Dynamic Organic Soil, Terrestrial Ecosystem Model (DVM-DOS-TEM, University of Alaska Fairbanks) into the PEcAn framework to enable formal model uncertainty quantification (UQ), parameterization, and data-
