Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects

Wildlife Biology, EarlyView.
Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)

Benefit or ecological trap? Monitoring the effects of small clear‐cuts on capercaillie Tetrao urogallus and its mammalian predators

Wildlife Biology, EarlyView.
The shift to ‘close to nature forestry' as the dominating forestry regime in western‐European forests has resulted in increasing timber volume and denser forests with negative effects on photophilic species. Hence, there is an increasing focus on active habitat management measures to support these species.

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.

Navigating a landscape of contrasting hunting regimes and habitats: red deer responses to risk and resources

Wildlife Biology, EarlyView.
Habitat selection of ungulates is influenced by various factors, with human interactions playing a significant role. Human disturbances through hunting strongly affect ungulate behaviour, often forcing them to modify their habitat choices by avoiding areas where the risk from humans outweighs other habitat benefits. Gaining insights into these dynamics

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.

Occurrence, morphology and growth of understory saplings in Swedish forests [PDF]

, 2004
Growing demands for a multipurpose forestry leads to increased use of silvicultural systems that avoid clear-cutting. Regeneration in such systems is based on establishment and ingrowth of new seedlings under a more or less closed canopy.

Comparative evaluation of noninvasive DNA sampling and line transect surveys for spring density estimation of black grouse and capercaillie

Wildlife Biology, EarlyView.
Reliable abundance estimates provide essential information in ecology, conservation and management of many wild grouse populations. In this 3‐year study, we comparatively evaluate the suitability of traditional line transect distance sampling of flushed birds versus a spatial capture–recapture survey with noninvasive DNA samples for individual ...

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.

Norway spruce in the Right Bank Forest-Steppe of Ukraine: perspectives of use and improvement of reproduction methods

Наукові праці Лісівничої академії наук України, 2018
Today, in Ukraine and abroad, the drying up of Norway spruce trees in forest plantations of different purpose has become a serious problem. Considering the important economic and social significance of spruce, studies of its condition, growth and ...

Climatic adaptation of seed maturity in Scots pine and Norway spruce populations

Silva Fennica, 2001
Seed maturation of Scots pine and Norway spruce in a provenance experiment at Kortkeros (northern Russia) was examined by the X-ray method. Logarithmic relationships were found between seed anatomy development and long-term average thermal sum.
