Nutrient dynamics and early decomposition rates of Picea abies needles in combination with Fagus orientalis leaf litter in an exogenous ecosystem

Annals of Forest Research, 2016
The Hyrcanian forests in the Northern Iran are originally poor of coniferous and are considered as a refugium of temperate broad-leaved trees during the Quaternary glaciations.

Anomalous roughening of wood fractured surfaces

, 1998
Scaling properties of wood fractured surfaces are obtained from samples of three different sizes. Two different woods are studied: Norway spruce and Maritime pine. Fracture surfaces are shown to display an anomalous dynamic scaling of the crack roughness.

Divergent selection predating the Last Glacial Maximum mainly acted on macro‐phenotypes in Norway spruce

Evolutionary Applications, 2023
The current distribution and population structure of many species were, to a large extent, shaped by cycles of isolation in glacial refugia and subsequent population expansions.

Coccinellidae on native and introduced spruce in central Europe: conservation implications in urban areas

Frontiers in Ecology and Evolution
The abundance and species composition of adult ladybird communities (Coleoptera: Coccinellidae) were investigated on two congeneric trees, native Norway spruce (Picea abies) and the introduced blue spruce (Picea pungens), at four locations in Slovakia ...

Aspects of hybrid larch (Larix X eurolepis Henry) as a potential tree species in southern Swedish forestry [PDF]

, 2003
The interest in growing hybrid larch (Larix × eurolepis Henry) in southern Sweden has increased in recent decades, one of its assumed advantages being high volume growth.

Relationships between tree and soil properties in Picea abies and Pinus sylvestris forests in Sweden [PDF]

, 2010
The exchange of elements between plants and the soil in which they are growing creates reciprocal control of their element composition. Within plants, the growth rate hypothesis from ecological stoichiometry implies a strong coupling between C, N, and P.

From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp

Journal of Applied Polymer Science, EarlyView.
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating

Aspects of precommercial thinning in heterogeneous forests in southern Sweden [PDF]

, 2005
The overall objective of the work underlying this thesis was to suggest and evaluate possible strategies for the tending of young heterogeneous stands of Norway spruce, Scots pine and birch in southern Sweden.

EcoViz: a tool for visual analysis and photorealistic rendering of forest landscape model simulations

Ecography, EarlyView.
Simulation outputs from forest landscape models are complex, and tools for their visual analysis and effective communication are often limited. In this paper, we present EcoViz, a novel, open‐source visualisation platform designed to complement existing forest models by providing advanced 3D visualisation capabilities.

Transcript profiling for early stages during embryo development in Scots pine [PDF]

, 2016
Background: Characterization of the expression and function of genes regulating embryo development in conifers is interesting from an evolutionary point of view.
