Decreasing water availability reduces productivity in Swiss forests along an altitudinal gradient

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests are one of the most important terrestrial carbon sinks, but are increasingly under pressure due to drought, heat and the occurrence of extreme events. There are opposing longer term trends for European forest growth reported, and severe drought and disturbance ...

Boron retranslocation in Scots pine and Norway spruce [PDF]

Tree Physiology, 2004
We previously traced 10B-enriched boric acid from shoots to roots to demonstrate the translocation of boron (B) in Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.) seedlings. To gain a more detailed understanding of B translocation, we sought: (1) to demonstrate B retranslocation directly, by showing that foliar-applied 10B ...

Seasonal flight patterns of the Spruce bark beetle (Ips typographus) in Sweden [PDF]

, 2012
The major bark beetle threat to Norway spruce (Picea abies (L.) Karst.) in Eurasia is the spruce bark beetle Ips typographus. Beetles cause damage after population build-up in defenseless trees.

Ectomycorrhizal community composition and extramatrical hyphal proportion predict soil carbon stocks at the landscape scale

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract While fungal composition has been linked to soil carbon at global scales, these patterns are often difficult to disentangle from broad climatic gradients and species range limits. To address this constraint, we tested which aspects of ectomycorrhizal community structure

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.

Induced Resistance to Pathogenic Fungi in Norway Spruce [PDF]

Plant Physiology, 1999
Abstract Norway spruce (Picea abies) trees (approximately 16 m high) of a single clone were used to study the effects of fungal infection and wounding on induction of resistance to the bark beetle-associated bluestain fungusCeratocystis polonica.

Asymmetric niche partitioning in large omnivores in response to anthropogenic disturbances within subarctic ecosystems

Journal of Animal Ecology, EarlyView.
Anthropogenic disturbances associated with mineral extraction influenced space use and activity patterns in grizzly bears, and to a much lesser extent in black bears, in a subarctic ecosystem, signalling an asymmetric response. Abstract Niche partitioning is an evolutionary process that allows the coexistence of multiple species in a landscape. However,

Flavanone-3-Hydroxylase Plays an Important Role in the Biosynthesis of Spruce Phenolic Defenses Against Bark Beetles and Their Fungal Associates

Frontiers in Plant Science, 2019
Conifer forests worldwide are becoming increasingly vulnerable to attacks by bark beetles and their fungal associates due to the effects of global warming.

Vehicle‐assisted suicidal strangulation: A case report and literature review

Journal of Forensic Sciences, EarlyView.
Abstract Vehicle‐assisted suicidal strangulation is an unusual method of suicide where the victim completes suicide by pulling a ligature tied around their neck using the acceleration of the vehicle they are driving. This report describes a case of a 48‐year‐old man who completed suicide by tying a rope to his neck and to a parked tractor, then using ...

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.
