Impact of pine looper defoliation in Scots pine [PDF]
, 2003 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.

Comparison of wood properties of Parana pine and Scots pine
Silva Fennica, 1977 According to the available literature, the appearance of Parana pine ( (Bertol.) Kuntze) wood resembles that of Scots pine ( L.). The anatomy is quite different, however. There are no resin canals and fusiform rays with resin canals in Parana pine.

Forest floor bryophyte and lichen diversity in Scots pine and Norway spruce production forests
, 2021 Bryophytes and lichens are two main components of the forest floor vegetation. They provide essential ecosystem services, including nutrient recycling and water regulation. Here, we contrast the species richness, cover and community composition of forest

Architecture of Scots pine crown. [PDF]
Silva Fennica, 1986 Dimensions (length, width and thickness) of needles in crowns of young Scots pine ( L.) were found to be related linearly to each other. Similarly, the needle area was linearly correlated with the needle biomass. In the lower crown, needle length was linearly correlated with the length of the shoot, but in the upper crown needle length did not vary ...

GEOGRAPHICAL VARIATION IN THE INBREEDING DEPRESSION OF SCOTS PINE [PDF]
Evolution, 1996 The magnitude of inbreeding depression caused by recessive mutations in a population is dependent on the mutation rate and on the intensity of selection against the mutations. We studied geographical differences in the level of early inbreeding depression of Scots pine in a common garden experiment.
