This report describes an international summer course, "Tree Rings, Climate, Natural Resources, and Human Interaction", held in Cheriomushki, Russia, in the summer of 2018. The course was attended by 12 participants from six countries (Belgium, India, Lebanon, Poland, Russia, and South Africa) and...

We have reviewed 43 studies related to dendroclimatology in Kazakhstan, and additionally 13 studies related to other subfields of dendrochronology, which have been published during the past 40 years. This review also includes studies published in Russian, Kazakh, German and Chinese languages, which ...

Although two centennial Scots pine chronologies for the dating of timber in Lithuania were constructed in the 2000s, the Baltic countries still lack a network of regional chronologies. To fill this gap, we constructed three Scots pine chronologies for western, central and eastern Lithuania. Here we ...

It has recently become a matter of discussion whether it is correct to use regional tree-ring chronologies in spatiotemporal climate reconstructions, since natural and climatic conditions in the regions may be heterogeneous, varying on different scales (from micro to global). We have studied the...

'Blue rings' (BRs) are visual indicators of less lignified cell walls typically formed towards the end of a tree's growing season. Though BRs have been associated with ephemeral surface cooling, often following large volcanic eruptions, the intensity of cold spells necessary to produce BRs, as well ...

Forest plantations are more vulnerable to the stress induced by biotic and abiotic factors than are naturally regenerated forests. These effects can be aggravated by a lack of management in large reforestation areas, and thinning could, therefore, help trees to reduce dieback and tree mortality...

Bulk wood density measurements are recognized for their utility in ecology, industry, and biomass estimations. In tree-ring research, microdensitometric techniques are widely used, but their ability to determine the correct central tendency has been questioned. Though rarely used, it may be...

Dendrochronology is a well-established dating method for wooden objects, but due to surface processing of construction timber or natural degradation the dating of historical wood often relies on a prediction of the number of missing rings based on sapwood statistics. Since Scots pine (Pinus...

Tree growth trends can affect the interpretation of the response of tree-ring proxies (especially tree-ring width) to climate in the low-frequency band, which in turn may limit quantitative understanding of centennial-scale climate variability. As such, it is difficult to determine if long-term...

The aim of this study was to compare the climatic responses of three tree rings proxies: tree ring width (TRW), maximum latewood density (MXD), and blue intensity (BI). For this study, 20 cores of Pinus sylvestris covering the period 1886-2015 were extracted from living non-damaged trees from the...
