Visual and Machine Strength Gradings of Scots and Red Pine Structural Timber Pieces from Türkiye
Scots (Pinus sylvestris L.) and red pine (Pinus brutia Ten.) structural timbers (540 pieces) from Türkiye were first visually graded according to TS 1265 (2012). Then, non-destructive tests were conducted using vibration and time of flight (ToF) methods,

The aim of this study was to experimentally test the most favourable seeding times for Scots pine (Pinus sylvestris L.), and to compare Scots pine and lodgepole pine (Pinus contorta Douglas ex Loudon) in respect to suitable seeding times and site factors.

ABSTRACT Two large‐scale experiments investigated fire spread mechanisms in vegetation ground fires in a pine forest and an agricultural field within the European TREEADS project. The tests, conducted in Saxony‐Anhalt and Brandenburg, targeted regions with dry, sandy soils and extensive pine stands and aim to improve suppression strategies and wildfire

Impact of pine looper defoliation in Scots pine
Widespread defoliation of forests caused by insects or fungi cause economic losses throughout the world. Successful outbreak management involves cost/benefit estimation and requires knowledge of potential yield losses. Currently, such knowledge is scarce. This thesis evaluates the significance of single-year defoliation by the pine looper moth (Bupalus

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.

Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

Strength of Scots pine branches
Empirical measurements showed that the strength of a dead branch of Scots pine ( L.) was related to the second power of the branch diameter and the third power of the basic density of branch wood. The same factors affected also the strength of living branches. Especially, the contribution of wood density was important.
