Bottom sediments of the proglacial Lake Donguz-Orun situated at ∼2500 m a.s.l. in the Elbrus Region (Central Caucasus) reveal regular laminae, characteristic of proglacial varved lakes. This is the first laminated sediment sequence recorded in the

The analysis of the anatomical characteristics of tree rings of P. sylvestris L. rootstocks and scions of P. sibirica Du Tour (Emelianovo and Surgut provenances) and P. cembra L. (Karpat provenance) has been carried out for 10 years of their joint gr

We developed a long (600-year) dataset for the concentrations of 26 elements in tree rings of larch from the Taymir Peninsula, the northernmost region in the world (ca. 72°N) where trees grow. Tree rings corresponding to the time period from 1300 to

Analysis of the radial growth and of the climatic response of heterografts of Siberian pine (Pinus sibirica Du Tour) and Swiss pine (Pinus cembra L.) from three provenances was conducted. In all of the cases the rootstock was Scots pine (Pinus sylves

Grafting can occur naturally between branches or more often roots of the same species, or artificially via asexual propagation where the tissues of two plants are encouraged to fuse with one another. Artificial grafting is commonly used for propagati

Cores of bottom sediments of Lake Karakel (Northern Caucasus) were obtained in 2010 and 2014 to perform geochemical studies for reconstructing the regional paleoclimate of the late Holocene. Solid samples of bottom sediments were scanned via micro-XR

Bottom sediments from Lake Kucherlinskoe that contain finely-laminated layers are studied using micro-XRF on synchrotron radiation beams from the VEPP-3 storage ring. Samples with visible layers are prepared as solid specimens impregnated with epoxy.

This study analyses dynamics of the hydrological regime of Bele-Shira closed basin and evaluates the potential for using radial growth of Siberian larch (Larix sibirica) for its assessment. We investigated the relationships between different characte

Traditionally the registration of seasonal changes in plant growth and development has been carried out phenologically, i.e., qualitatively using visual inspection. However, since the process of plant acclimatization to winter dormancy involves rever

This paper presents a method for classification of trees in groups depending on parameters of the age trend in tree-ring width. The method is tested on a sample containing 194 trees of Scots pine (Pinus sylvestris L.) growing in the forest-steppe zon
