Summary: In this study, the abundances of two morphologically similar and coexisting diatom species, Ulnaria acus and Fragilaria radians, were compared using molecular data. By reanalyzing published sequences with an ASV-based pipeline and a specific classification routine, the relative abundances of the two species were estimated, increasing the precision compared to traditional OTU-based analyses. Existing data allowed for qualitative comparisons between these species that cannot be differentiated by other methods, revealing distinct seasonal peaks and spatial distributions of F. radians and U. acus.

Summary: This review discusses the temporal and spatial distribution of surface uplift in the Tibetan Plateau and the geodynamic mechanisms behind it. The initial collision between India and Asia and the subsequent formation of the high Tibetan Plateau are still not well understood, but the uplift is primarily controlled by delamination and break-off of the subducted Indian and Asian lithosphere.

Summary: This study evaluates the dissimilarity between modern and fossil plant taxa assemblages in lake sediments from the south-eastern Tibetan Plateau and northern Siberia, revealing that sedDNA is more efficient in finding modern analogues compared to pollen. This suggests that a quantitative vegetation reconstruction based on sedaDNA using MAT is more reliable than pollen-based reconstructions due to the easier relationship between sedDNA assemblages and surrounding vegetation.

Summary: The Tibetan Plateau vortices are the major precipitation-producing weather systems on the plateau, with a more significant impact in the warm season but also important in certain regions during the cold season. The interannual variation of vortices and associated precipitation is mainly determined by the number of vortices, while the heating anomaly caused by the Tibetan Plateau thermodynamic effect is also a significant factor.

Summary: During the extreme warming period, surface temperatures in glacial regions of the Tibetan Plateau have increased faster than non-glacial areas, and the duration and intensity of glacier surface heatwaves have significantly increased. These changes may pose potential threats to the sustainability of glacier water resources and increase the risk of glacier related hazards.

Summary: The Tibetan Plateau (TP) experiences increasing precipitation trends in the northern region but not in the southern region, which is attributed to the activities of Tibetan Plateau vortices (TPVs). The significant warming over the TP influences the genesis frequency of TPVs differently in the north and south, leading to distinct precipitation trends in the two regions.

Summary: This study explores the relationship between lakes and Tibetan antelopes in the vulnerable Tibetan Plateau. It found that areas with larger lakes and flatter terrain tend to have a higher population of Tibetan antelopes. Additionally, vegetation cover and plant diversity are higher near the lake compared to farther away. These findings suggest that lakes offer Tibetan antelopes a richer food supply and reduced predation risk. The study provides new perspectives for understanding the cross-ecosystem impacts of climate change.

Summary: In 2019, Lake Tzibana in southeastern Mexico experienced a significant water level decline, which exposed the Naha River Delta. The research demonstrates that changes in water level in lakes can impact the sedimentary dynamics in deltaic areas and provide valuable paleolimnological information. Understanding these past lake-level reductions is crucial for both local communities and the conservation of this internationally important ecosystem.

Summary: Recent changes in the climate and environment of the Tibetan Plateau have been influenced by variations in the Westerlies and the Indian summer monsoon. However, there is a lack of understanding regarding long-term shifts in atmospheric circulation during the transitional seasons. By studying the distribution of Tsuga pollen, researchers have identified it as an indicator of variable atmospheric circulation in spring. The results suggest the existence of a potential particle transport pathway from the southern slope of the Himalayas to the interior of the plateau during the late Holocene spring.

Summary: This study systematically assesses the ecological impact of different types of tephra layers on the same lake ecosystem and highlights the importance of lake background conditions in mediating the impact of tephra. Thicker tephra layers induce pronounced changes in lake conditions and diatom communities, while thinner layers have minimal effects. Thicker layers decrease water-column phosphorus and potentially increase silica, leading to changes in the composition of diatom communities.

Summary: The recent rise in air temperatures at high altitudes of the Tibetan Plateau has led to increased glacier melt and retreat, as well as enhanced monsoonal precipitation and increased runoff in lakes. These changes have resulted in rising water levels and alterations in the composition of local aquatic biota. Analysis of sediment cores from Nam Co, an endorheic lake, revealed an increase in chironomid richness since 1956, indicating higher water temperatures and intensified primary productivity. The dominance of littoral chironomid assemblages further suggests increasing lake water levels and flooded shorelines due to increased precipitation and glacial meltwater input.

Summary: Nitrogen deposition and soil acidification have negative effects on soil functioning, health, and biodiversity, but their effects on functional genes are poorly understood. This study used metabarcoding and metagenomics to investigate the responses of soil functional genes to nitrogen deposition along a natural soil pH gradient. The results showed that soil acidity strongly affected the relative abundances of most metabolic gene categories. Soil pH was the most important factor affecting microbial and functional gene composition, while the effects of nitrogen deposition were less significant. The diversity-function relationship reported for other organisms also applies to soil microbiomes.

Summary: During investigations on freshwater diatoms in Qinghai Province, China, four Surirella species were studied. Three of these species were identified as S. minuta, S. lacrimula, and S. brebissonii var. kuetzingii based on morphological observations using light and scanning electron microscopy. A new species, Surirella liubingii sp. nov., was also described, characterized by its unique distribution pattern of costa-stria bundles and over-fibula costae, the presence of robust fibulae and a pseudoseptum internally, and the presence of only one portula between two adjacent fibulae.

Summary: Two new species of Oricymba, O. sinensis and O. fanjingensis, were discovered as important components of freshwater river benthos in China. These species have distinct characteristics including conspicuous dorsiventrality, shallow grooves, and higher areola density. The unique feature of their apical pore fields, which possess internal apertures covered by an undulate flap-like silica strip, should be considered an important distinguishing feature for Cymbelloid diatoms.

Summary: Clear-cutting is the main forest management method in boreal and hemiboreal forests. The implementation of clear-cutting has raised concerns due to its effects on biodiversity, including soil fungal biota. This study aimed to assess the factors affecting fungal assemblages and changes in soil fungal diversity after clear-cutting in spruce and pine stands. The results showed that soil fungal communities were affected immediately after clear-cutting, but recovered within one year. The relative abundance of ectomycorrhizal fungi declined, while saprotrophs and pathogens increased.

Summary: This study used African clawed frogs to investigate the effects of polyethylene microplastic (MP) ingestion on amphibian growth, development, and metabolism across two consecutive life stages, as well as the interaction between MP ingestion and rearing temperature. The results showed that MP ingestion had sublethal effects on larval growth, development, and metabolism, and led to morphological changes in juveniles. MP was also found to accumulate in both life stages. These findings indicate that juvenile amphibians may play a role in the transfer of MP from freshwater to terrestrial environments.

Summary: The composition of dissolved organic matter (DOM) in lakes is influenced by multiple environmental factors at a continental scale. The study conducted in China's 182 lakes revealed that land cover and societal development have a positive direct effect on the quantity of DOM in lakes. Climate, on the other hand, has both a warming effect on soil organic matter production and export, and an enhancing effect on in-lake transformation of DOM. Three indicators were proposed to assess the influence of biogeochemical drivers on lake DOM across different ecoclimatic zones.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
