Summary: This study genetically characterized the Sicilian population of the European pine marten for the first time, showing that it is a native species that colonized the island during the Pleistocene and has a well-differentiated endemic lineage. The discovery of a previously unknown major phylogroup of the species in Sicily highlights the need for dedicated monitoring and conservation efforts to protect this evolutionarily significant population.

Summary: This study investigates the surface processes in the Tengger Desert of China and their response to long-term global cooling. The study suggests that glaciation in high latitudes and high mountains of the Northern Hemisphere have a significant impact on wind-blown sand and fluvial sand in Chinese deserts.

Summary: Holocene climate warming has significant impacts on the population structure and gene flow of the cold-adapted water strider Aquarius paludum. The study reveals two phylogeographic lineages that diverged in the middle Pleistocene, resulting in a west-east genetic pattern. In the Holocene, the western and eastern lineages had a second contact, forming a temporary hybrid zone in the arid-semiarid regions of China. The future prediction suggests the possible existence of a novel northern corridor that would intensify the west-east gene flow.

Summary: This study used a novel perspective to examine the influence of various factors on regional diversity patterns in Trichoptera at the genus level across different regions. The results showed that taxonomic diversity was not related to latitude and the biogeographical history played an important role in shaping community composition.

Summary: The Yedoma Ice Complex in northern Yakutia provides ideal preservation conditions for frozen remains of vertebrate animals. This study focuses on characterizing mammal bones from late Pleistocene and Holocene permafrost deposits in the Oyogos Yar coast. The distribution of bones and teeth along the coastal permafrost exposure is not uniform and shows similarities with other Yedoma outcrops in the region.

Summary: Diplomystidae is a family of freshwater catfish that has been discovered in a new location in southern South America. The study suggests that this population may have survived in the basin during the Last Glacial Maximum, indicating the importance of glacial history in shaping freshwater biodiversity in the region.

Summary: Through a comprehensive study combining morphology, molecular data, biogeography and climatic niche models, we have identified five distinct species within the debated group of pampas cats, no longer recognizing subspecies and designating neotypes for the two most controversial species. The diversification of pampas cats is associated with Middle Pleistocene glaciations, with additional genetic samples from the central Andean region needed to conclusively reconstruct their evolutionary history.

Summary: The bumble bee fauna of Kolguev Island in the Russian Arctic is poorly studied. This study examines the bumble bees on the island, analyzes their phylogeographic data, discusses possible scenarios explaining their origin, and describes their biology and phenology. Five bumble bee species were found on the island, which are also widespread in the Eurasian Arctic. The bumble bee populations on Kolguev Island have low molecular divergence from mainland populations. The lack of rodents greatly reduces available nesting places for bumble bees on the island.

Summary: The study found that glacial cycles had an impact on the distribution of Arctic shorebirds, resulting in range fragmentation. The Pleistocene climatic cycles drove the diversification of Arctic shorebirds, with variations in species' distribution changes between different regions and habitats shaping current shorebird diversity patterns.

Summary: This study investigates the cryogenic structuring in the watershed landscapes of the Central Russian Plain. Through the use of aerial and satellite imagery and geological investigation techniques, the researchers were able to identify and correlate three generations of wedge casts and a specific bulbous type of cast. These cryogenic features provide valuable information for paleoenvironmental reconstructions. However, the regular polygonal patterns caused by these features are almost erased in the modern topography.

Summary: The study revealed that genetic admixture during glacial periods and post-glacial colonization of sky islands played a significant role in shaping the genomic variation patterns of the two grasshopper species in Southeastern Spain. Additionally, isolation in sky islands led to high genetic fragmentation and reduced levels of local genetic diversity.

Summary: Studies suggest that a period of intense erosion affecting the cratonic shields surrounding the North Atlantic between Marine Isotope Stages 27 and 25 may have been responsible for a major ocean circulation weakening between MIS 25 and 21, coinciding with the onset of 100-ky interglacial-glacial cycles in the Northern Hemisphere. This erosion may have been induced through regolith loss and increased exposure of the crystalline bedrock, enabling larger ice sheets characteristic of the 100-ky cycles.

Summary: The sediment core ARC5-ICE6 from the Makarov Basin provides insights into circum-Arctic glaciation and surface-ocean circulation history during the Middle to Late Pleistocene. Sedimentary proxies indicate predominant sediment delivery from the Eurasian shelves and glaciated mainland, with large shifts in sediment inputs and provenance between glacial and interglacial periods since Marine Isotope Stage 6. Strong cyclonic circulation and different glaciogenic sourcing are proposed for various events within Marine Isotope Stages 5 and 3, with limited glacial influence inferred for Stage 3.

Summary: Sediment cores from the Northwind Ridge north of the Arctic Chukchi-Alaskan margin were analyzed to study the sedimentary environments of Marine Isotope Stages (MIS) 1-11 on millennial time scales. The study characterized contrasting glacial-interglacial conditions and provenance using clay-mineral and geochemical proxies, providing insights into the paleocirculation and glaciations in the western Arctic Ocean.

Summary: This study documents a glacial lake-outburst flood in the Adamow region of south-central Poland during the maximum phase of the Wartanian Glaciation. The analysis of sediments and hydraulic features reveals the significant impact of these floods on shaping the marginal zones and foreland of ice sheets in the North European Plain.

Summary: This paper presents new field and laboratory data combined with previously published materials on interglacial sediments underlying two upper tills of northern European Russia and West Siberia, discussing the Atlantic marine invasion during the late Middle Pleistocene and a warmer climate than today based on forest pollen spectra in the European Northeast. The evidence suggests at least two saline Atlantic water invasions into northern Russia during the last 250 kyears, contradicting the model of the unique boreal transgression and providing a new intra-regional stratigraphic marker for the northern Pleistocene.

Summary: This study provides an explanatory note for the sketch map of loessoids, which includes loess and various loess-like deposits. The map is a byproduct of the ongoing Quaternary Map project of the Russian Federation and is based on national geological maps and literary data. The distribution and classification of loessoids reveal their stratigraphic and geographical variations. Regardless of their origin and geographical diversity, all loessoids share the fundamental feature of paleosols.

Summary: This study synthesizes sea-level proxies for the last interglacial period in the glaciated Northern Hemisphere and explores factors such as sea-level rise and glacial retreat. The results show that sea level during the last interglacial period was higher than at present, providing valuable insights for predicting future sea-level rise.
