Species-specific forest variable estimation using non-parametric modeling of multi-spectral photogrammetric point cloud data [PDF]
The recent development in software for automatic photogrammetric processing of multispectral aerial imagery, and the growing nation-wide availability of Digital Elevation Model (DEM) data, are about to revolutionize data capture for forest management ...

Developmental phase transitions in Norway spruce
Plant development proceeds through distinct phases that are controlled by complex networks of regulatory genetic circuits and fine-tuned by environmental and endogenous cues. Many of these regulatory networks have been unraveled in annual and perennial angiosperms, while they remain predominantly unknown in ecologically and economically important ...

Abstract European forests are increasingly managed to harmonize production goals with biodiversity conservation, through practices such as retention and close‐to‐nature forestry. Forest birds may benefit from these practices, but it remains unclear how the effects of different management practices compare, and whether responses to management are driven

Abstract There is limited understanding on how complex interdependencies among large herbivore grazing, competitive and facilitative interactions among plants, and the changes in temperatures and precipitation shape northern boreal and subarctic ecosystems.

Resistance of thermo-hygro-mechanically (THM) densified wood to degradation by white rot fungi [PDF]
Colonisation and degradation by the white rot fungi, Trametes versicolor and T. pubescens, were studied in wood of Norway spruce and beech subjected to three different treatments: (1) hygro-thermal treatment (160°C and 180°C), (2) mechanical ...

In 2018 the Vaia windstorm caused severe damage to much of the woodland habitat of the golden Alpine salamander (Salamandra atra aurorae), an endangered subspecies endemic to the Venetian Prealps, the consequences of which are still being understood. We profiled the bacterial and fungal skin microbiota of 56 golden Alpine salamanders from forest plots ...

Programmed cell death and genetic stability in conifer embryogenesis [PDF]
Somatic embryogenesis, the generation of embryos from somatic cells, is a valuable tool for studying embryology. In addition, somatic embryos can be used for large-scale vegetative propagation, an application of great interest for forestry.

This systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperature, while work at lower limits is more evenly distributed across water availability, plant–plant interactions, and selection/local adaptation.

Chemical defence in Norway spruce
Norway spruce (Picea abies) responds to stress by biosynthesis of chemical substances, which can deter invading insects or pathogens. Some of these substances are volatile and can be emitted to the surroundings while others are accumulated within the tree.

Variation in seed abundance predicts yolk fatty acid composition in a wild population of birds
Bird embryos develop inside eggs, which contain maternal substances that can shape offspring phenotype and fitness. Yolk fatty acids are a key energy source for the developing embryo, with omega‐6 (ω‐6) and omega‐3 (ω‐3) polyunsaturated fatty acids (PUFAs) obtained exclusively from the diet.
