Diamonds of the Morgogor Placer (Anabar, Yakutia)

Geology of Ore Deposits, 2023
Research subject. The placer diamond deposit of the Morgogor River, Anabar, Yakutia. The geological history of this deposit has not been reliably established, and the root sources remain unknown. Aim. To describe the mineralogical and spectroscopic characteristics of diamonds from the Morgogor river deposit in comparison with the previously studied ...

Phylogenomics and revised classification of Lymexyloidea and Tenebrionoidea (Coleoptera: Polyphaga: Cucujiformia)

Systematic Entomology, Volume 50, Issue 4, Page 794-812, October 2025.
Using a large‐scale phylogenomic dataset, we provide the robustly supported phylogeny of the wider Tenebrionoid clade, with Lymexyloidea sister to the mordelloid clade (Mordellidae and Ripiphoridae) + remaining Tenebrionoidea. Lymexyloidea contained two newly circumscribed families, each of them with two subfamilies, and both Mordellidae and ...

Quantifying Changing Groundwater Exfiltration at a High Arctic Site due to Climate Change

Hydrological Processes, Volume 39, Issue 8, August 2025.
To understand how climate change is affecting northern hydrology, we use a combination of climate model results and numerical groundwater models to project future groundwater discharge rates to an arctic lake. We find that the active layer thickens and stays open longer, leading to increased groundwater flow to the lake.

Landsat-Based Trend Analysis of Lake Dynamics across Northern Permafrost Regions [PDF]

, 2017
Lakes are a ubiquitous landscape feature in northern permafrost regions. They have a strong impact on carbon, energy and water fluxes and can be quite responsive to climate change.

Vegetation and environmental dynamics in the central part of the Kola Peninsula during the past 13.3 ka as reflected by ancient plant DNA on sediments from Lake Imandra

Journal of Quaternary Science, Volume 40, Issue 6, Page 1070-1096, August 2025.
ABSTRACT The first high‐resolution reconstruction of the vegetation and environmental changes during the last ca 13 300 cal a BP in the central part of the Kola Peninsula (NW Russia) was reconstructed based on sedimentary ancient DNA (sedaDNA) metabarcoding on sediment core Co1410 from Lake Imandra.

Ecological training set of freshwater ostracods in Canadian and Siberian periglacial regions [PDF]

, 2008
Quantified palaeoenvironmental reconstructions are essential to estimate the impact of future climate changes on ecosystems. Based on faunistic data from regional multireference sites and limnological surveys, ecological training sets can be used to ...

Environmental changes on the northern Taymyr Peninsula (Russian Arctic) during the last 62 ka inferred from the lacustrine pollen record

Boreas, Volume 54, Issue 3, Page 431-446, July 2025.
Environmental changes on the northern part of Taymyr Peninsula during the last 62 ka were reconstructed based on pollen assemblages throughout a 46‐m‐long sediment core from Lake Levinson‐Lessing (74°27′54″N, 98°39′58″E). Environmental changes on the northern Taymyr Peninsula were reconstructed based on a new pollen record from a 46‐m‐long sediment ...

Hydroclimatic development from the Early Holocene to anthropogenic times: a comparative study of diatom oxygen isotope records and multiproxy data from Lake Khamra, eastern Siberia

Boreas, Volume 54, Issue 3, Page 447-467, July 2025.
Northern Eurasia underwent major hydroclimatic changes since the beginning of the Holocene interglacial. A rapid warming period reaching the Holocene Thermal Maximum (HTM), followed by a general cooling trend until recent times, was observed in Eurasian lacustrine diatom oxygen isotope (δ18Odiatom) records.
