Departing With the Wind: Spring Migration Timing in Brent Geese From Their Most Important Staging and Wintering Site, the Wadden Sea World Heritage Site. [PDF]

Ecol Evol
The timing of migratory departure reflects a balance between endogenous schedules and transient environmental opportunities. By linking GPS‐derived departure events with hourly atmospheric data, we demonstrate that wind assistance strongly increases departure probability in Brent Geese, while this selectivity weakens over time as migratory urgency ...

The water column of the Yamal tundra lakes as a microbial filter preventing methane emission [PDF]

Biogeosciences, 2021
Microbiological, molecular ecological, biogeochemical, and isotope geochemical research was carried out in four lakes of the central part of the Yamal Peninsula in the area of continuous permafrost. Two of them were large (73.6 and 118.6 ha) and deep (up

Localized Vegetation, Soil Moisture, and Ice Content Offset Permafrost Degradation under Climate Warming

Geosciences, 2023
Rapid Arctic warming is expected to result in widespread permafrost degradation. However, observations show that site-specific conditions (vegetation and soils) may offset the reaction of permafrost to climate change.
