Harm to the Resources of Traditional Nature Management and Its Economic Evaluation [PDF]

Экономика региона, 2017
The Yamal region occupies the fifth part of the Yamal-Nenets Autonomous District. Therefore it is one of the territories where traditional natural resource management is mainly developing. Its key branches are reindeer herding and fisheries.

Oxygen stable isotope variation in Late Holocene ice wedges in Yamal Peninsula and Svalbard

, 2020
The stable oxygen isotope composition of Late Holocene syngenetic ice wedges from the Erkutayakha River valley in the Yamal Peninsula and from the Adventdalen valley in Svalbard was studied. It was demonstrated that the studied ice wedges located 2000 km

Mapping Arctic Lake Ice Backscatter Anomalies Using Sentinel-1 Time Series on Google Earth Engine

Remote Sensing, 2021
Seepage of geological methane through sediments of Arctic lakes might contribute conceivably to the atmospheric methane budget. However, the abundance and precise locations of such seeps are poorly quantified.

A Hybrid LSTM‐KAN Framework With Dynamic Residual and Adaptive Grid for Robust Wind Speed Forecasting

Wind Energy, Volume 29, Issue 9, September 2026.
ABSTRACT Accurate wind speed forecasting is indispensable for the efficient integration of wind power into the electrical grid, optimizing turbine scheduling, and ensuring grid stability. Existing models, such as Long Short‐Term Memory (LSTM) networks, often struggle to capture the highly nonlinear relationships and long‐range dependencies present in ...

Commercially Exploited Seaweed Species in Africa: Occurrences, Chemical Composition, Current Value Chain and Opportunities for Value Addition

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Commercially exploited seaweed species in Africa, their biochemical composition, current uses, and value chain are reviewed. Potential value‐addition of seaweed is suggested regionally in Africa amongst countries producing similar seaweed species. ABSTRACT Africa has a wide range of coastal environments that support a diverse array of seaweed species ...

Pollen and spore record of lake sediments, the southern part of the Yamal peninsula, Russia

, 2021
Palynological data have been obtained from the lake sediments, the southern part of the Yamal peninsula. For the spore-pollen analysis we used a 30 cm core of bottom sediments from one of the water bodies of the Yerkuta river basin with the code name K1 (

Cladocera remains in reconstructions of past ecological conditions of the Yamal Peninsula

Limnology and Freshwater Biology, 2022
Abstract. The aim of this study is to explore the Cladocera community from the bottom sediments of small unnamed lake (21-Ya-02B) whilst attempt to reconstruct the ecological and climatic conditions for the Yamal Peninsula. In total, remains of 37 taxa were identified in bottom sediments of the lake.

Saline Permafrost and Cryopegs as Potentially Important Sources of CO2—Assessing Organic Carbon Mineralization Potentials on the Alaskan Coastal Plain

Global Change Biology, Volume 32, Issue 7, July 2026.
Incubation experiments reveal that potentially carbon‐rich saline permafrost and cryopegs from Arctic coastal plains exhibit CO2 production potentials comparable to active layers. This could substantially shift greenhouse gas balances, as salinity is currently not accounted for in permafrost carbon assessments.

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra

Ecography, Volume 2026, Issue 6, June 2026.
Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.
