Identifying Timber Species by Diffuse Reflection Spectra in the Near-Infrared Region Using a Linear Discriminant Analysis

Теория и практика судебной экспертизы, 2022
The article presents an algorithm of analysis of coniferous timber materials (Pinus sylvestris L., Pinus sibirica Du Tour, Larix decidua Mill., Abies alba L. and Picea abies (L.) Karst.) using the spectroscopy method in the near-infrared region.

Weather Conditionality of Siberian Stone Pine (Pinus sibirica Du Tour) Seeding

Lesnoy Zhurnal (Forestry Journal), 2021
The dynamics of Siberian stone pine sexual reproduction in the South-Eastern part of the West Siberian Plain was studied by 13-year stationary observations. The stand age was 160–180 years, the average tree height was 22 m, and the average diameter of the trunk at breast height was 53 cm.

A new approach to developing a logistic regression model variables to predict tree mortality, based on tree-ring growth dynamics [PDF]

Сибирский лесной журнал, 2020
The annual tree increment is one of the integral indicators of abiotic and biotic processes occurring in the forest ecosystem. The use of logistic regression models based on annual tree-ring growth data is a promising approach to studying tree mortality.

Glacial refugia, postglacial dynamics, and hybrid zones of Pinaceae in Eurasia captured from sedimentary ancient DNA

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Boreal forests cover nearly one‐third of global forest area. Glacial cycles have shaped the distribution and connectivity of modern Pinaceae genera, yet species‐level refugia, postglacial migrations, and hybridization patterns remain unclear due to limited high‐resolution taxonomic and temporal data. We applied a hybridization capture approach

Monitoring Brown Bears in Kazakhstan: A Pilot Study from the Altai Mountain Region

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Here, we present results from the first camera trapping operation designed to detect brown bears in the Altai Mountain Region of Kazahstan and highlight some lessons learned from the pilot study. Our study was conducted at a relatively local scale but represents a first step towards understanding the presence of brown bears and other mammals in a ...

Biological Flora of Britain and Ireland: Geranium sylvaticum*

Journal of Ecology, Volume 114, Issue 2, February 2026.
Geranium sylvaticum is a perennial forb of upland grasslands, woodlands and riverbanks in northern Britain, with scattered native occurrences also in Wales, central England and Northern Ireland. It has an extensive native range in Europe and Asia. The species is gynodioecious, with individual plants typically female or hermaphrodite.

Cave Palaeolithic of the Ural Mountains – a review

Boreas, Volume 55, Issue 1, Page 4-28, January 2026.
The Ural Mountains are of fundamental importance for studying early human migrations along the geographical limits between Europe and Asia. Geological processes and past climates gave rise to numerous caves, mostly in Palaeozoic carbonate formations.

An integrative strategy used by the aphid Uroleucon formosanum to counter host sesquiterpene lactone defense: Insights from combined genomic and transcriptomic analysis

Insect Science, Volume 32, Issue 4, Page 1155-1173, August 2025.
We report the first high‐quality chromosome‐level genome assembly for the aphid Uroleucon formosanum, a serious pest that infests lettuce in eastern Asia. A combination of comparative genomic analyses and RNA‐seq transcriptome profiling suggests that U. formosanum employs integrative mechanisms to cope with host plant‐derived sesquiterpene lactone (STL)
