Effects of mild drought on the morphology of sun and shade needles in 20-year-old Norway spruce trees
(Journal article; Peer reviewed, 2019-02-28)Several studies have looked at how individual environmental factors influence needle morphology in conifer trees, but interacting effects between drought and canopy position have received little attention. In this study, ... -
Hydraulic and mechanical dysfunction of Norway spruce sapwood due to extreme summer drought in Scandinavia
(Journal article; Peer reviewed, 2017-12-22)Projected climate change scenarios such as frequently occurring dry summer spells are an enormous threat to the health of boreal conifer forests. We identified visible features indicating wood with tracheids predisposed ... -
Stem taper and bark functions for Norway spruce in Norway
(Journal article; Peer reviewed, 2019-09-16)Based on data from long-term experimental fields with Norway spruce (Picea abies (L.) H. Karst.), we developed new stem taper and bark functions for Norway. Data was collected from 477 trees in stands across Norway. Three ... -
Successful reproduction and pheromone production by the spruce bark beetle in evolutionary naïve spruce hosts with familiar terpenoid defences
(Journal article; Peer reviewed, 2018-02)1. The European spruce bark beetle Ips typographus is a damaging pest on spruce in Europe. Beetle interactions with tree species originating outside the natural range of the beetle are largely unknown and may be unpredictable ... -
The Ratio between Field Attractive and Background Volatiles Encodes Host-Plant Recognition in a Specialist Moth
(Journal article; Peer reviewed, 2017-12-22)Volatiles emitted by plants convey an array of information through different trophic levels. Animals such as host-seeking herbivores encounter plumes with filaments from both host and non-host plants. While studies showed ...
