Summary: Recent Arctic warming has significant impacts on biological communities in freshwater environments, with evidence of changes in lake ecosystems in the Canadian Arctic and Fennoscandia linked to human-induced climate warming. However, there is a lack of data from the Russian Arctic linking recent climatic changes with biological community changes. The study found that changes in biological communities were correlated with meteorologically recorded climatic parameters, with the strongest taxonomic shifts observed in 1880 and 1980.

Summary: The diatom oxygen isotope composition from Lake Bolshoye Shchuchye in Arctic Russia is analyzed to understand the hydrological and climate dynamics. The study reveals that the diatom oxygen isotope record is associated with changes in summer insolation and Northern Hemisphere temperature. Short-term variations in the record are attributed to variations in snow melt and influx. This is the first study to identify such drastic centennial-scale hydrological changes in Holocene diatom oxygen isotopes.

Summary: The study examines millennial-scale climate change history in eastern Siberia by analyzing multi-proxy time series derived from sediment cores of Lake Bolshoe Toko in southeastern Yakutia, Russia. The changes in diatom species abundances are related to repeated episodes of thermal stratification and specifically to the onset of the Holocene Thermal Maximum. The analysis also reveals relationships between sediment-geochemical data, paleoclimate variability, and diatom species richness, showing a lag in changes of diatom alpha diversity behind deposited organic carbon concentrations.

Summary: Multiple stressors impact water quality and biodiversity in lakes worldwide, but the understanding of their effects is fragmented. This study in Canadian lakes found greater turnover of diatom functional groups in high human impact sites, with similar trends in chironomid and cladoceran groups. Differences in temporal turnover and sensitivity across ecozones suggest variations in response to human impacts.

Summary: The grass family is responsible for most pollen allergies. Climate change is expected to increase the severity of pollen-based asthma and allergies. Current pollen monitoring techniques have limitations in identifying grass species, resulting in grouping them all together. To address this issue, researchers used phenological data from herbarium specimens and pollen monitoring data to determine the response of flowering time to climate change for 12 allergenic grass species. They found that pollen season duration is lasting longer and starting earlier, and the maximum pollen loads are occurring earlier in response to climate warming.

Summary: This study reconstructs changes in terrestrial vegetation composition and taxa richness in the southeastern Yakutia region during the late Pleistocene and early Holocene, using pollen and sedimentary ancient DNA records. It shows significant changes in vegetation between the late Pleistocene and early Holocene, with an increase in tree and shrub taxa richness. The sedaDNA method suggests higher plant diversity in the late Pleistocene steppe-tundra due to the presence of megaherbivores, which is discussed in relation to the widely accepted species-area hypothesis.

Summary: This study uses sedimentary proxy records from Lake Satagay in Central Yakutia, Siberia to examine the long-term relationships between fire regime and forest structure. The results show that high amounts of burnt biomass were present during the Early Holocene, while the present-day low-severity surface fire regime has been in place since around 4,500 years ago. The study also reveals a shift in forest structure towards a mixed larch-dominated closed-canopy forest during the Mid-Holocene.

Summary: This study reconstructs the Holocene shore displacement of the Vastervik-Gamlebyviken area in Sweden and provides evidence for the transgressions of the Littorina Sea. Sediment cores were analyzed to determine the sea level changes and the results show an initial transgression at 8.5 ka BP, a rise in sea level between 8.0 and 7.5 ka BP, and a highstand at around 22 m a.s.l. between 7.5 and 6.2 ka BP. These findings are consistent with the Littorina Sea transgressions in southern Sweden and the deglaciation of North America.
