Major decline in fires in coniferous forests – reconstructing the phenomenon and seeking for the cause

Silva Fennica, 2011
Steep decline in forest fires about a century ago occurred in coniferous forests over large areas in North America and Fennoscandia. This poorly understood phenomenon has been explained by different factors in different regions.

The Long Arc of Forest Land Dispossession and Degradation—Firm and State Actions on Sámi Lands in the Wood‐Based Commodity Frontier in Northern Sweden, 1673–1955

Journal of Agrarian Change, EarlyView.
ABSTRACT This article presents a new way of obtaining deep explanations of environmental problems. We expose the production strategies, corporate strategies and state actions that have been taken by firms and state agencies to facilitate the geographical expansion of the wood‐based commodity frontier at the expense of reindeer pastoralists among the ...

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

Sedimentology, EarlyView.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

Problems of Precambrian paleomagnetism on the territory of Ukraine

Геофизический журнал, 2018
Some problems of paleomagnetic research of the Precambrian rocks of Ukraine are considered. The results of paleomagnetic researches of the Proterozoic rocks of the Ukrainian Shield, Ediacaran traps of Volyn and sedimentary rocks of Podolia were analyzed.

Long‐term effects of clear‐cutting forestry on ectomycorrhizal fungi in boreal forest

New Phytologist, Volume 251, Issue 5, Page 2818-2831, September 2026.
Summary Clear‐cutting is detrimental to ectomycorrhizal fungi in a short time perspective, but long‐term effects on species richness and community composition are uncertain. To evaluate ecological sustainability of rotation forestry, we examined to what extent communities similar to those in old forests develop within the time frame of a rotation ...

TERRITORIAL DEVELOPMENT IN THE GREEN BELT OF FENNOSCANDIA BASED ON TOURISM ACTIVATION

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2019
Borderland municipalities traversed by the Green Belt of Fennoscandia are facing a difficult socio-economic situation, but nature conservation areas in their territories posses a substantial potential and offer opportunities for tourism development.

A fission track data compilation for Fennoscandia

Norsk Geologisk Tidsskrift, 2007
A compilation of fission track data is presented here to show from where fission track data are available in Fennoscandia and to highlight potential targets for future research. Because of the relatively small number of fission track data for zircon and titanite, emphasis is put on apatite fission track data.

Birch Rust Spore Exposure and Upper Airway Symptom Dynamics in a Subarctic Region: Indications for a Novel Seasonal Allergen

Clinical and Translational Allergy, Volume 16, Issue 8, August 2026.
ABSTRACT Background Airway allergies affect 20%–30% of the global population, with pollen and fungal spores representing major environmental triggers. Although fungal spores are far more abundant than pollen, their allergenic role—particularly from phytopathogenic rust fungi such as birch rust (BR)—remains poorly understood.

Centennial‐scale phosphorus accumulation drives regeneration and internal loading in a boreal lake

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Legacy anthropogenic phosphorus (P) accumulated in sediments drives internal P loading in eutrophic lakes. However, predicting the temporal response of internal P loading to the external loading reduction is difficult due to the complexity of sedimentary P cycling. In this study, we use geochemical profiles obtained from a 180‐cm sediment core
