Ozone detoxification of steam-pretreated Norway spruce [PDF]
Biotechnology for Biofuels, 2015 Pretreatment of lignocellulose for biochemical conversion commonly results in formation of by-products that inhibit microorganisms and cellulolytic enzymes. To make bioconversion processes more efficient, inhibition problems can be alleviated through conditioning.

Impregnation of Norway spruce (Picea abies L. Karst.) wood with hydrophobic oil [PDF]
, 2006 The overall goal of this thesis was to develop new knowledge to facilitate the production of Norway spruce wood-based materials that are more durable and more homogenous than current materials by using a hydrophobic oil impregnation process). Linseed oil

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)

Lignin studies of transgenic Norway spruce [PDF]
, 2006 An attractive objective in tree breeding is to reduce the content of lignin, or increase its extractability, to favor delignification during pulping. This study investigates the potential for lignin alterations in Norway spruce (Picea abies [L.] Karst ...

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.

Journal of Forest Science, 2018 The effects of silver fir (Abies alba Miller) on the soil compared to Norway spruce (Picea abies (Linnaeus) H. Karsten) were evaluated. Altitude of the study site is 790 m a.s.l., mild slope of 10° facing SW, forest site is spruce-beech on acid soil. The

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 ...

Picein and piceol concentrations in Norway spruce
Ecotoxicology and Environmental Safety, 1990 The concentrations of the glucoside picein and its aglucone piceol (4-hydroxy acetophenone) in the needles of Norway spruce (Picea abies (L.) Karsten) are considered indicators of plant stress. By use of two clones and a natural population of Norway spruce it was shown that the picein concentration was dependent on the site and the provenance of the ...

Wildlife Biology, EarlyView.Predation by pine martens Martes martes and red foxes Vulpes vulpes is an important factor influencing the population dynamics of capercaillie Tetrao urogallus. However, there is a knowledge gap regarding the relative effects of these mesopredators on the reproductive success of capercaillie. To better understand how various landscape factors influence

Trees, Forests and PeopleWe examined the effects of drought-induced stress on foliar litter production, nutrient contents, and nutrient masses in mature European beech (Fagus sylvatica [L.]) and Norway spruce (Picea abies [L.] Karst.) over a two-year period (October 2015 ...
