Tree Stands and Their Productivity Dynamics at the Upper Growing Limit in Khibiny on the Background of Modern Climate Changes [PDF]

open access: yes, 2019
Within the ecotone of the upper limit of woody vegetation on the southeastern macroslope of the Khibiny Mountain ridge (Kola Peninsula), the spatial and age structure, as well as features of the phytomass accumulation of spruce–birch stands, were studied.

Anthropogenic interference and climatic change control long‐term dissolved silicate variation in the Yellow River

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Dissolved silicate (DSi) export from rivers is shaped by both natural processes and human activities. Using long‐term observations at Lijin station combined with chemical weathering and reservoir silicon cycling models, we reconstructed annual DSi fluxes and source‐sink dynamics in the Yellow River Basin since the 1980s.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Phonographic Recordings in Finno‐Ugric Languages in Finnish Archives

open access: yesMuseum Anthropology, Volume 49, Issue 1, Spring 2026.
ABSTRACT This review discusses audio recordings made by Finnish scholars among the Russian Arctic people in the early twentieth century and stored in various archives in Finland. The background of the recordings, together with their broader meaning and the possibilities for research they offer, is brought out.

“Seen Again”: Ethnography, Immersive Technologies, and Temporality in the Siberian Collections at the Pitt Rivers Museum

open access: yesMuseum Anthropology, Volume 49, Issue 1, Spring 2026.
ABSTRACT This paper proposes Virtual Reality (VR) and 360 film as promising fieldwork tools for addressing problematic temporalities in ethnographic museums and for collaborating with communities of origin. Focusing on the Maria Czaplicka Siberian collections at the Pitt Rivers Museum, Oxford, we examine how previous methods of display marginalized the
