Using long‐term tree diversity experiments to explore the mechanisms of temporal shifts in forest ecosystem functioning

Oikos, Volume 2025, Issue 4, April 2025.
Plant diversity is known to influence ecosystem functioning, but the strength and direction of this relationship vary considerably among studies, most of which have a short duration. In communities with long‐lived species, such as forests, traits of individual trees change from seedlings to maturity, and the environment in which trees grow also ...

Biodiversity and ecosystem service contributions of trees: A review for environmental risk assessments of non‐native plant pests in Sweden

Food Risk Assess Europe, Volume 3, Issue 2, April 2025.
Abstract Plant pests, particularly non‐native species, can have a profound impact on their host plants. Trees are the foundation of forest ecosystems and serve as important structures in agricultural landscapes and urban areas. In Sweden, forests cover around 70 % of Sweden's land area and serve as an important national resource for the economy and for

Weather conditions favouring cone initiation for Siberian stone pine (Pinus sibirica Du Tour)

FORESTRY BULLETIN, 2023
Seed production in 25 trees of Siberian stone pine (age 180-200 years) over a 28-year period was examined to determine how the weather factors and their period influence strobilus initiation. Since floral induction in Siberian stone pine occurs in a short period of time only during three weeks at the end of summer, the dynamics of temperature and ...

Lightweight Natural Fiber Insulation Boards Produced with Kapok Fiber (Ceiba Pentandra) and Polylactic Acid or Bicomponent Fiber as a Binder

Global Challenges, Volume 9, Issue 3, March 2025.
This research explores the creation of lightweight insulation boards through a hot‐air process, utilizing kapok fibers and polylactic acid (PLA) as a binding agent. Both components are derived from natural resources and are regarded as naturally renewable.

Population genetic structure and mating system in the hybrid zone between Pinus sibirica Du Tour and P. pumila (Pall.) Regel at the Eastern Baikal Lake shore

Annals of Forest Research, 2013
Genetic structure of sympatric Pinus sibirica Du Tour and P. pumila (Pall.) Regel populations and putative interspecific hybrids between them was analyzed in the Baikal Lake region (Barguzin Biosphere Natural Reserve, Davsha River basin) by means of 31 ...

What Are the Limits to the Growth of Boreal Fires?

Global Change Biology, Volume 31, Issue 3, March 2025.
Fires in East Siberia have been increasing, releasing record greenhouse gas emissions. To understand what stops these fires from spreading, we analyzed fire perimeters from satellite data covering 27,000 fires between 2012 and 2022. We found that fire weather conditions and landscape features, like roads and previous burns, play key roles in limiting ...

Cell culture in vitro in studying of intraspecies genetic polymorphism in Pinus sibirica Du Tour

BULLETIN OF THE L.N. GUMILYOV EURASIAN NATIONAL UNIVERSITY. BIOSCIENCE SERIES, 2020
The authors have studied characteristics of callusogenesis in Siberian pine (Pinus sibirica) trees of two populations: the control population and the population of elite (plus) trees. For the population of plus trees, the appearance of callus culture on the explants of buds and needles occurred earlier than in the control population. Differences in the
