Three tree-ring chronologies of white pine (Pinus strobus), a species which are non-native to Europe, were constructed for Suuremõisa, Jädivere and Järvselja sites in Estonia. These chronologies were related to instrumental climate records and Scots pine (P. sylvestris) chronologies from nearby sites. Growth rates of P. strobus exceeded those of P. sylvestris. The chronologies of the non-native and native pine species relatively well correlated with each other. Moreover, tree-ring growth of both species correlated positively with late-winter and spring (February–May) temperatures and negatively with spring (April) precipitation. While P. strobus growth was positively associated with summer precipitation, the growth of P. sylvestris remained positively related to the growing season temperatures. Both species exhibited a negative growth anomaly from 1939 to 1942.   Keywords: Pinus strobus, Pinus sylvestris, dendroclimatology, Estonia

Scots pine is an adaptable and prevalent European tree species that grows naturally throughout Europe and has been planted in a wide range of environments. Previous studies have indicated that climatic variables affect tree-ring growth patterns in this species, but it is also possible that certain aspects of the growth environment moderate this response. In order to understand the potential impact a shifting climate has on this important species, this study compared the growth response of two populations of Scots pine. Trees from similar bioclimatic regions in Hungary and Poland were compared using the hypothesis that differences in the association between climate and growth would be reflected by the degree of tree-ring width variation. We also wanted to know how changing climatic conditions influenced the temporal stability of the climate–growth signal in the most important periods for tree growth. Clear similarities in the effect of temperature and precipitation on tree-ring width variation were found between the two sites, but there were also some interesting differences. In the late winter to early spring period both populations reacted to warming with a decreasing association with temperature. Summer precipitation was shown to be the dominant factor in controlling ring-width. A decreasing trend in summer precipitation values at both Hungarian and Polish sites resulted in a weakening in correspondence for the Hungarian trees, while the Polish trees showed a significant increase in correlation with summer precipitation. The results indicated that changes in climate influenced the studied trees in different ways which has implications for the future balance of Scots pine growth in Europe.

The distribution of eastern white pine (Pinus strobus L.) is described using Canada's Forest Inventory to map volume levels of the species and to tabulate its occurrence by Forest Region and forest type. White pine grows under a wide variety of conditions, with most volume occurring in mixedwood forest. The highest concentrations are in SE Ontario, SW Quebec, and the Maritime provinces.

Studies over a 30-month period revealed the presence of a seasonal rhythm in water content in the sapwood and in wet and dry portions of the heartwood of eastern white pine, Pinus strobus L. The data, indicated an increase in water content in late autumn and early winter, a drying out in late winter, a slight increase in the spring, fluctuations during the summer strongly influenced by weather, and a slight decrease in early autumn prior to the increase at the end of the year. The newest parts of the crown were the wettest in the tree. Outer rings in the sapwood of the crown were wetter than those in the bole and butt. Wet heartwood possessed as high a water content as sapwood, whereas dry heartwood contained the lowest water content of all the parts of the tree examined.

Abstract Scots pine (Pinus sylvestris L.) trees growing on shingle fields offer a unique possibility to reconstruct precipitation and study climate variability in the fairly humid eastern part of central Sweden. Tree-ring characteristics were compared with monthly (1890–2001) and daily (1961–2001) climate data from an adjacent meteorological station. Chronologies for latewood (LW), earlywood (EW), and tree-ring widths (RW) were constructed from 73 living and dead trees. Correlation analyses show that tree growth is most sensitive to early summer precipitation. EW shows the strongest correlation with precipitation in May and June while LW is best correlated with June and July precipitation. A reconstruction model for May–June precipitation was calculated using principal component analysis (PCA) regression (regular regression) including EW, LW, and RW for present and previous years. The model explained 46% of the variation in May–June precipitation and allowed a reconstruction back to 1560. Information about wet and dry years was collected from historical documents and was used to validate the result. Periods with precipitation above and below the mean show agreement with previous reconstructions of spring precipitation from tree rings in Finland and of spring floods from estuary sediments in the region. Analyses of correlations between meteorological stations and reconstructed precipitation show that the model is valid for the coastal part of central Sweden. The authors conclude that Scots pine trees on shingle fields are well suited for precipitation reconstruction, and the separate analyses of LW and EW improve the reconstruction.

AbstractThe weevils Hylobius radicis Buchanan and Hylobius pales (Herbst) survived to adulthood more frequently, developed more rapidly, and weighed more as adults when reared on diet containing ground phloem from Scots pine, Pinus sylvestris L., or red pine, Pinus resinosa Aiton, than from jack pine, Pinus banksiana Lamb., or eastern white pine, Pinus strobus L. In feeding tests, both weevils preferred Scots pine, although jack pine was preferred over red and white pine. When reared on diets containing phloem from red pines which had received various amounts of nitrogenous fertilizer, H. radicis and H. pales performed significantly better at elevated concentrations of nitrogen. Hylobius radicis adults exhibited a feeding preference for twigs from red pines containing elevated nitrogen concentrations.
