Summary: In this study, the larvae of certain subgenera of Chironomidae were described and identified, providing important information on freshwater macroinvertebrate indicators. Morphometric characters were used to distinguish larval species, but association with pupal exuviae was still necessary for identification. The development of DNA barcodes is recommended for future research as a more accurate identification tool.

Summary: The Azokh Cave in the Southern Caucasus is an important site for the study of human evolution. Through the analysis of small-mammal remains, researchers can infer the climatic and environmental conditions during the formation of the site. The findings suggest that the site had temperatures and precipitation similar to the present day, with a mainly desert and steppe habitat.

Summary: The study on a Late Glacial lake sediment sequence reveals similar trends in oxygen isotope records of chironomid head capsules and endogenic carbonate, but temperature reconstructions based on these values are often unrealistic, indicating potential diagenetic alteration of the chironomid capsules.

Summary: In this study, we compared cladoceran assemblages in water column, contemporary, and pre-industrial sediment samples across many lakes. We found that contemporary and pre-industrial sediment samples showed the highest congruence, indicating that water column samples may not accurately represent littoral taxa. However, in high impacted catchments, water column and contemporary sediment samples showed greater similarity, suggesting that water quality stressors may influence assemblages in parallel directions over time. Lake depth and pH were identified as the most important structuring variables across Canada.

Summary: The Voronin Grotto is a new site where a large number of vertebrate remains and artifacts were found, indicating regular human visits over the past 3310 years in a landscape dominated by forests and open meadows. The climate transitioned from slightly milder to colder with no dry season, and fluctuations in forest and open meadow ratios suggest possible anthropic influences.

Summary: Quantifying changes in land surface height is crucial for understanding Earth processes, but uncertainties in elevation reconstructions largely stem from unconstrained thermal lapse rates. Using paleoclimate models can reduce and quantify uncertainties, improving predictive skill in estimating elevation changes.

Summary: This study investigates the adaptation of plant communities in Atacama Desert to extreme climatic conditions through the analysis of leaf wax content and composition. The results reveal a species-specific chemotaxonomy linked to climatic conditions and demonstrate that leaf wax content obtained from ancient rodent middens can serve as a reliable hydroclimate proxy for the region.

Summary: This paper describes and illustrates three new species of Byrsopteryx from Peru, with distinct wing coloration and male genitalia characteristics. Byrsopteryx inti sp. nov. and Byrsopteryx mamaocllo sp. nov. share a unique feature on male forewings, while Byrsopteryx mancocapac sp. nov. has distinctive spine-like processes and divided posterior margin on sternum VIII. Larvae of the latter two species are similar to other known Byrsopteryx larvae, but can be differentiated by specific morphological characteristics. Phylogenetic analysis suggests close relationship between B. inti sp. nov. and B. mamaocllo sp. nov., despite a 14.9% minimum genetic divergence.

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 larva of Miocora aurea (Ris, 1918) was discovered in the forested streams of Tatama National Park in the Colombian Western Andes. This study describes and illustrates the final larval stage, highlighting the distinguishing features such as the length of the antennal pedicel, prementum, and the posterior margin of tergite 10, which differentiate it from the larva of M. chirripa (Calvert, 1917).

Summary: This study investigates the effects of graphene oxide (GO) on the midge Chironomus riparius. The results show that GO does not impact the survival rate, but does have chronic toxicity in a dose-dependent manner. GO exposure leads to inhibited larval growth and a significant reduction in length. However, there is no increased occurrence or severity of mouthpart deformities in larvae exposed to GO.

Summary: This study describes a rare aquatic insect, Diamesa caucasica, found in the watercourses of the Terek River basin in the Caucasus region. The species is likely endemic to the glacial streams of the Terek River basin and has not been recorded in other mountainous regions of Europe. The research includes a morphological redescription of the adult male of the species and DNA barcoding based on samples collected from glacial streams in North Ossetia.

Summary: An organic-rich deposit was discovered at an elevation of 480 m above sea level at the Pingorsuit Glacier in North-West Greenland. The sediments contained remains of vascular plants, mosses, beetles, caddisflies, midges, bryozoans, sponges and other invertebrates. The fossils were deposited in a boreal environment with a mean July air temperature that was at least 9 degrees C higher than at present.

Summary: High-resolution chronologies are crucial for comparing palaeoenvironmental studies with high-precision historical, archaeological, or climatic data. The study presents an updated sediment chronology from Burgaschisee, a well-studied lake in Switzerland, using new radiocarbon samples and Bayesian age-depth modeling. The new chronology reveals 2 sigma uncertainties of only +/- 19 years for the entire record and allows for more accurate site-to-site comparisons. The study emphasizes the importance of a rigorous sampling strategy and the selection of suitable terrestrial plant material for radiocarbon dating.

Summary: Adaptive radiations play a crucial role in generating biodiversity, but the relative importance of species' ecological versatility and arrival order in determining which lineage radiates is still unclear. Through analyzing the fossil record of cichlid fishes in Lake Victoria, it was found that their ecological versatility was key to their persistence in new habitats, suggesting that it played a major role in adaptive radiation.
