Threshold loss of discontinuous permafrost and landscape evolution
Global Change Biology, 2016AbstractThis study demonstrates linkages between the 1997/1998 El Niño/Southern Oscillation index and a threshold shift to increased permafrost loss within a southern Taiga Plains watershed, Northwest Territories, Canada. Three‐dimensional contraction of permafrost plateaus and changes in vegetation structural characteristics are determined from ...

Mountain permafrost landscapes of Yakutia
Geography and Natural Resources, 2009Abstract An analysis is made of the spectrum of altitudinal zonality of mountain permafrost landscapes of Yakutia. The intervals of the values of characteristics of particular landscape altitudinal zones are provided, namely, the marks of their boundaries in accordance with a change in the latitude of the locality, the indices of freezing and thawing,

Current State of Permafrost Landscapes of the Prilensky Plateau
Geoinformatika, 2023The article presents the results of studying the structure of permafrost landscapes in the area of discontinuous distribution of permafrost soils in large-scale mapping. The actual material was collected by the authors in the course of research and field work on the Power of Siberia project.

Drivers of fish biodiversity in a rapidly changing permafrost landscape
Freshwater Biology, 2021Abstract Rapid environmental change occurring in northern permafrost regions may have profound implications for fish biodiversity but remains poorly understood. Climate change, increasing human development, and resultant permafrost thaw may combine to alter the quality and quantity of fish habitat including reductions in preferred thermal habitat ...

Landscape-driven carbon export from small coastal permafrost watersheds
2020<p>Ongoing climate warming in the western Canadian Arctic is leading to thawing of permafrost soils and subsequent mobilization of its organic matter (OM) pool. Part of this mobilized terrestrial OM enters the aquatic system as dissolved organic matter (DOM) and is laterally transported from land to sea.

Airborne Bacteria over Thawing Permafrost Landscapes in the Arctic
Environmental Science & TechnologyRapid warming in the Arctic, outpacing global rates, is driving significant changes in cryospheric landscapes, including the release of long-preserved microorganisms. This study focuses on thawing permafrost in Northern Alaska, where microbes previously preserved in frozen soils are introduced into thermokarst lakes, rivers, and coastal waters and may ...

Changes in Permafrost Landscapes Under Global Change
2001Permafrost is susceptible to subtle changes in environmental conditions, including climate and surface disturbance. Relative to climate, land use is anticipated to be a more important component of global change in the coming decades. However, climate is anticipated to surpass land use as a factor later in the next century, particularly in the Arctic ...

The Mackenzie Delta: An Archetypal Permafrost Landscape
2009The Mackenzie Delta, in Canada’s western Arctic, is North America’s largest arctic delta. For over half the year the rivers and lakes of this vast alluvial plain are ice covered. Permafrost is ubiquitous in the delta and the surrounding landscape. Treeline traverses the delta, separating closed-canopy white spruce forests in southern parts from low ...
