Effects of Volatile Emissions of Picea abies Fresh Debris on Ips duplicatus Response to Characteristic Synthetic Pheromone

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2012
Ips duplicatus is an important pest of Norway spruce (Picea abies) planted outside of its natural range. This species uses olfactory signals to identify the spruce trees favourable for colonisation. The knowledge of the beetles’ response to these stimuli

Nutrient dynamics and early decomposition rates of Picea abies needles in combination with Fagus orientalis leaf litter in an exogenous ecosystem

Annals of Forest Research, 2016
The Hyrcanian forests in the Northern Iran are originally poor of coniferous and are considered as a refugium of temperate broad-leaved trees during the Quaternary glaciations.

Divergent selection predating the Last Glacial Maximum mainly acted on macro‐phenotypes in Norway spruce

Evolutionary Applications, 2023
The current distribution and population structure of many species were, to a large extent, shaped by cycles of isolation in glacial refugia and subsequent population expansions.

Stem taper and bark functions for Norway spruce in Norway [PDF]

Silva Fennica, 2019
Based on data from long-term experimental fields with Norway spruce ( (L.) H. Karst.), we developed new stem taper and bark functions for Norway. Data was collected from 477 trees in stands across Norway. Three candidate functions which have shown good performance in previous studies (Kozak 02, Kozak 97 and Bi) were fitted to the data as fixed-effects ...

Response of mature Norway spruce (Picea abies) to elevated atmospheric CO² [PDF]

, 2014
The aim of this thesis was to identify pathways and rates of C allocation in tall forest trees, and to identify effects of elevated CO2 on respiratory processes and root growth.

Coccinellidae on native and introduced spruce in central Europe: conservation implications in urban areas

Frontiers in Ecology and Evolution
The abundance and species composition of adult ladybird communities (Coleoptera: Coccinellidae) were investigated on two congeneric trees, native Norway spruce (Picea abies) and the introduced blue spruce (Picea pungens), at four locations in Slovakia ...

Establishment of Heterobasidion annosum s.l. infections in young Norway spruce dominated stands [PDF]

, 2013
One of the worst pathogens on Norway spruce, Heterobasidion annosum s.l., can establish in previously healthy trees by spores landing on freshly made stumps from where mycelia can grow via root grafts and contacts to the adjacent tree.

Using dendroclimatic analysis of exotic deciduous conifers in an arboretum to document tree growth in response to climate change, Northeast Ohio, USA

PLANTS, PEOPLE, PLANET, EarlyView.
Rising temperatures and wetter conditions in the Midcontinent of North America are influencing climate responses in trees. Dendroclimatological analyses of four exotic deciduous conifer species from Secrest Arboretum, Northeast Ohio help identify past, present and future climate‐tree interactions.

Effects of simultaneous ozone and nitrogen exposure on two tree species : Fagus sylvatica (L.) and Picea abies (L.) Karst. [PDF]

, 2005
Tropospheric ozone (O3) and nitrogen deposition (N) are considered as two of the most important anthropogenic pollution factors for temperate forests today.
