The microRNA response associated with methyl jasmonate-induced resistance in Norway spruce bark
(Peer reviewed; Journal article, 2021-05-15)Methyl jasmonate (MeJA) treatment elicits induced resistance (IR) against pests and diseases in Norway spruce (Picea abies). We recently demonstrated using mRNA-seq that this MeJA-IR is associated with both a prolonged ... -
Timber volume estimation based on airborne laser scanning — comparing the use of national forest inventory and forest management inventory data
(Peer reviewed; Journal article, 2021-05-17)Key message Large-scale forest resource maps based on national forest inventory (NFI) data and airborne laser scanning may facilitate synergies between NFIs and forest management inventories (FMIs). A comparison of models ... -
Hyperspectral NIR time series imaging used as a new method for estimating the moisture content dynamics of thermally modified Scots pine
(Peer reviewed; Journal article, 2020-06-04)The purpose of this research is to develop a method for estimating the spatially and temporally resolved moisture content of thermally modified Scots pine (Pinus sylvestris) using remote sensing. Hyperspectral time series ... -
Mixing effects on Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.) productivity along a climatic gradient across Europe
(Peer reviewed; Journal article, 2020-12-15)Mixed-species stands have been found to be more productive than would be expected from the performance of their component species in monocultures due to facilitation and complementarity between species, although these ... -
Lignification and cell wall thickening of ray parenchyma cells in Scots pine sapwood
(Peer reviewed; Journal article, 2021-05-26)Scots pine exhibits variations in ray anatomy, which are poorly understood. Some ray parenchyma cells develop thick and lignified cell walls before heartwood formation. We hypothesized that some stands and trees show high ... -
Tamm Review: Individual-based forest management or Seeing the trees for the forest
(Peer reviewed; Journal article, 2021-09-15)In the last century, local or individual-based forest management was introduced by various forest scientists including Schädelin, Abetz and Pollanschütz as an alternative to traditional global thinning methods. They suggested ... -
Site carrying capacity of Norway spruce and Scots pine stands has increased in Germany and northern Europe
(Peer reviewed; Journal article, 2021-04-10)The maximum size-density relationship describes site carrying capacity, i.e., the maximum number of trees of a given size that can be stocked per unit area (self-thinning line). We analysed whether the self-thinning lines ... -
Dry weight minimum in the underground storage and proliferation organs of six creeping perennial weeds
(Peer reviewed; Journal article, 2021-05-06)Many herbaceous perennial plant species gain significant competitive advantages from their underground creeping storage and proliferation organs (CR), making them more likely to become successful weeds or invasive plants. ... -

Thermal modification of wood—a review: chemical changes and hygroscopicity
(Peer reviewed; Journal article, 2021-01-07)Thermal modification is a well-established commercial technology for improving the dimensional stability and durability of timber. Numerous reviews of thermally modified timber (TMT) are to be found in the scientific ... -
Species stratification and weather conditions drive tree growth in Scots pine and Norway spruce mixed stands along Europe
(Peer reviewed; Journal article, 2020-11-01)Mixed forests are suggested as a strategic adaptation of forest management to climate change. Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.) are tree species of high economic and ecological ... -
76-year decline and recovery of aspen mediated by contrasting fire regimes: Longunburned, infrequent and frequent mixedseverity wildfire
(Peer reviewed; Journal article, 2021-02-04)Quaking aspen (Populus tremuloides) is a valued, minor component on northeastern California landscapes. It provides a wide range of ecosystem services and has been in decline throughout the region for the last century. ... -
