Robust reference gene selection in Norway spruce: essential for real-time quantitative PCR across different tissue, stress and developmental conditions

Frontiers in Forests and Global Change
Accurate gene expression analysis in Norway spruce (Picea abies) under diverse stress conditions requires the identification of stable reference genes for normalization.

A First Indication That Rainforest Vine Proliferation Does Not Enhance Predator–Prey Interactions on the Forest Floor

Entomologia Experimentalis et Applicata, EarlyView.
Vine proliferation is a widespread consequence of tropical forest disturbance, yet its effects on ground‐level predator–prey interactions remain poorly understood. Using plasticine caterpillars deployed on the rainforest floor in north Queensland, Australia, we show that overall predation rates were unaffected by vine‐to‐tree ratio. Instead, fine‐scale

Basic density and moisture content of coniferous branches and wood in Northern Norway

EPJ Web of Conferences, 2012
With the increasing demand for fuel the use of biomass from other tree components like branches and tops has increased rapidly. Norway has abundant raw material resources which can be use for bioenergy.

On Spatial Point Processes With Composition‐Valued Marks

International Statistical Review, EarlyView.
Summary Methods for marked spatial point processes with scalar marks have seen extensive development in recent years. While the impressive progress in data collection and storage capacities has yielded an immense increase in spatial point process data with highly challenging non‐scalar marks, methods for their analysis are not equally well developed ...

Differences in growth and wood properties between narrow and normal crowned types of Norway spruce grown at narrow spacing in Southern Finland

Silva Fennica, 2008
In recent years there has been increased interest in the so called narrow crowned Norway spruce (Picea abies f. pendula), which is a rare mutant of Norway spruce (Picea abies (L.) Karsten), as a suitable wood raw material source for pulp and paper ...

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 ...

Ecological and genomic variation in ectomycorrhizal fungal exploration types

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

Dual RNA-seq analysis provides new insights into interactions between Norway spruce and necrotrophic pathogen Heterobasidion annosum s.l.

BMC Plant Biology, 2019
Background Root and butt rot of conifer trees caused by fungi belonging to the Heterobasidion annosum species complex is one of the most economically important fungal diseases in commercial conifer plantations throughout the Northern hemisphere.

Ectomycorrhizal Cortinariaceae species dominate class II peroxidase gene expression in a boreal forest soil

New Phytologist, EarlyView.
Share of transcripts and ITS2 sequence for each gene families among identified fungal contigs and OTUs. Summary Boreal forest ecosystems constitute a large terrestrial reservoir of carbon. In these nitrogen‐limited environments, release of nutrients through decomposition of soil organic matter is of fundamental importance.

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

Plant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...
