Spontaneous Hybridization between Pinus mugo and Pinus sylvestris at the Lithuanian Seaside: A Morphological Survey

Early phenology and growth trait variation in closely related European pine species

Closely related taxa occupying different environments are valuable systems for studying evolution. In this study, we examined differences in early phenology (bud set, bud burst) and early growth in a common garden trial of closely related pine species: Pinus sylvestris, P. mugo, and P. uncinata. Seeds for the trial were sourced from populations across the ranges of each species in Europe. Over ...

Comparison of the bending-moment resistance of wood-plate and dowel joints in particleboard and lodgepole pine lumber

Contribution of ambient ozone to Scots pine defoliation and reduced growth in the Central European forests: a Lithuanian case study.

The study aimed to explore if changes in crown defoliation and stem growth of Scots pines (Pinus sylvestris L.) could be related to changes in ambient ozone (O(3)) concentration in central Europe. To meet this objective the study was performed in 3 Lithuanian national parks, close to the ICP integrated monitoring stations from which data on meteorology and pollution were provided. Contribution ...

Consequences for selected high-elevation butterflies and moths from the spread of Pinus mugo into the alpine zone in the High Sudetes Mountains

Due to changes in the global climate, isolated alpine sites have become one of the most vulnerable habitats worldwide. The indigenous fauna in these habitats is threatened by an invasive species, dwarf pine (Pinus mugo), which is highly competitive and could be important in determining the composition of the invertebrate community. In this study, the association of species richness and abundanc...

Gas exchange of the lowest branches of young Scots pine: a cost-benefit analysis of seasonal branch carbon budget.

A cost-benefit approach was developed to analyze the carbon budget of the lowest Scots pine (Pinus sylvestris L.) branches subject to abscission. In addition to within-branch growth and respiratory costs, the budget included an estimation of a branch's share of the maintenance respiration of the stem and root. A branch was considered productive if the budget was positive. Foliar gas exchange an...
