Assessment of LiDAR and Spectral Techniques for High-Resolution Mapping of Sporadic Permafrost on the Yukon-Kuskokwim Delta, Alaska

Remote Sensing, 2018
Western Alaska’s Yukon-Kuskokwim Delta (YKD) spans nearly 67,200 km2 and is among the largest and most productive coastal wetland ecosystems in the pan-Arctic. Permafrost currently forms extensive elevated plateaus on abandoned floodplain deposits of the

Mapping Arctic Tundra Vegetation Communities Using Field Spectroscopy and Multispectral Satellite Data in North Alaska, USA

Remote Sensing, 2016
The Arctic is currently undergoing intense changes in climate; vegetation composition and productivity are expected to respond to such changes. To understand the impacts of climate change on the function of Arctic tundra ecosystems within the global ...

Interactions between winter and summer herbivory affect spatial and temporal plant nutrient dynamics in tundra grassland communities [PDF]

, 2020
In the long‐term, herbivores can alter nutrient dynamics in terrestrial ecosystems by changing the functional composition of plant communities. Here, we ask to what extent herbivores can affect plant‐community nutrient dynamics in the short‐term.

The Ghost of Development Past: the Impact of Economic Security Policies on Saami Pastoral Ecosystems

Ecology and Society, 2011
To ensure economic viability over time, any efforts to meet the Millennium Development Goals need to reconcile conservation with development interventions. Particularly, in marginal and risk prone areas erosion of resilience could make production systems

Another Winter Tundra [PDF]

Clinical Chemistry, 2017
Cold, windy, the house creaking, feeling the low temperature from the outside world. Freeze nipping at my bare toes. Barren trees, grey against the monochromatic sky, seemingly lifeless land, snow starts falling, swirling through the air, so soft and gentle. As I peek out the window, it turns to sleet.

Taxonomic diversity and abundance of enchytraeids (Annelida, Clitellata, Enchytraeida) in the Northern Palaearctic. 1. Asian part [PDF]

Biodiversity Data Journal
Enchytraeids, or potworms, are tiny oligochaetes that are distributed worldwide in many terrestrial, freshwater and marine ecosystems. Despite their key role in the functioning of ecosystems, the diversity and abundance of Enchytraeidae are rarely ...

The effect of a permafrost disturbance on growing-season carbon-dioxide fluxes in a high Arctic tundra ecosystem [PDF]

Biogeosciences, 2016
Soil carbon stored in high-latitude permafrost landscapes is threatened by warming and could contribute significant amounts of carbon to the atmosphere and hydrosphere as permafrost thaws.
