Studies of the Belukha glacier plexus in the context of global glacio-climatic monitoring (on the 100th anniversary of the first ascent of the Belukha Mountain)

Лëд и снег, 2015
The Belukha Mountain is the highest peak of the Altai. On July 26 (7th August in the new time scale) of 1914 the brothers Boris and Mikhail Tronov discovered the mountain and were the first people to climb it. The Tronov Glacier is named after them.

Late Holocene history of the Shkhelda Glacier, Northern Caucasus, according to remote sensing, dendrochronology and cosmogenic (¹⁰Be) dating of moraines

Лëд и снег
The position of the Shkhelda valley glacier front (Elbrus region, 43.18N, 42.64 E) for the period from the 1880s to 2022 was reconstructed based on interpretation of aerial and satellite images and old maps.

A review of the Little Ice Age in Andalusia (Southern Spain): results and research challenges

Cuadernos de Investigación Geográfica, 2018
Andalusia (southern Spain) is a region of special climatic interest due to its geographical location, hydrological and orographical characteristics. In this work a summary of different approaches to study the Little Ice Age in this region is presented ...

Genome‐wide evolutionary response of European oaks during the Anthropocene

Evolution Letters, 2022
The pace of tree microevolution during Anthropocene warming is largely unknown. We used a retrospective approach to monitor genomic changes in oak trees since the Little Ice Age (LIA).

Accelerating Glacier Area Loss Across the Andes Since the Little Ice Age

Geophysical Research Letters
Andean glaciers are losing mass rapidly but a centennial‐scale context to those rates is lacking. Here we show the extent of >5,500 glaciers during the Little Ice Age chronozone (LIA; c. 1,400 to c.

Touching the cold in the Little Ice Age

Lychnos
Climate change urges us to reconsider the very cold. Its natural manifestations – ice and snow – are today shrinking elements, and the gravity of melting glaciers and thawing polar regions is indeed deeply worrying for the planet as a whole.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Dynamic LIA advances hastened the demise of small valley glaciers in central Svalbard

Arctic Science
Most small land-terminating glaciers in Svalbard have experienced large recession since the Little Ice Age (LIA) and today are thin, cold, and largely inactive. This likely contrasts to their LIA conditions, but the observational record from that time is
