Climate and Permafrost Shifts in Yakutia’s Arctic and Subarctic from 1965 to 2023

Land
By analyzing the last 50–60 years of climate changes in Arctic and Subarctic Yakutia, we have identified three distinct periods of climate development.

Landscape Effects of Wildfire on Permafrost Distribution in Interior Alaska Derived from Remote Sensing

Remote Sensing, 2016
Climate change coupled with an intensifying wildfire regime is becoming an important driver of permafrost loss and ecosystem change in the northern boreal forest.

Banking Biodiversity: Ex Vivo Solutions for a Planet in Crisis

Zoo Biology, EarlyView.
Genetic diversity is being lost faster than it can be cataloged. Biobanking preserves cells, gametes, and DNA as recoverable material for future conservation use, and delivers most when collections are established proactively rather than deployed once populations are already critically depleted.

Divergent Spatiotemporal Patterns and Climate Responses of Lateral and Internal Lake Drainage in the Northern Permafrost Region

Geophysical Research Letters
Lake drainage is a key manifestation of permafrost degradation with implications for hydrology, landscape dynamics and carbon feedbacks. Lake drainage occurs through two distinct mechanisms, namely lateral drainage and internal drainage.

Observing Seasonal Variabilities of a Permafrost Landscape With PolSAR, InSAR and Pol-InSAR [PDF]

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Synthetic aperture radar (SAR) remote sensing is an established approach for observing Earth processes. The combination of different types of SAR acquisitions in polarimetric, interferometric, and polarimetric-interferometric frameworks is well studied for retrieving parameters of certain landscape features, such as forests and glaciers.

Integrating large mammalian herbivores into Dynamic Global Vegetation Models: Status and next steps

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Zoogeochemistry, the study of how animals influence elemental cycling within ecosystems, bridges the fields of zoology, ecology and biogeochemistry. Yet, most terrestrial ecosystem models, especially Dynamic Global Vegetation Models (DGVMs), remain largely plant‐centric

Icings and groundwater conditions in permafrost catchments of northwestern Canada

Scientific Reports, 2020
Icings are sheet-like masses of ice that form on the ground surface or in fluvial channels from groundwater seepage. Although the presence of icings in the landscape is known, few studies investigated their regional distribution and explored relations ...
