Summary: Hydrological periods can impact the water quality of lentic ecosystems, leading to changes in the diatom species composition and ecological condition. Evaluating different diatom metrics can help identify the best indicators for assessing the ecological status of these ecosystems during different hydrological periods.

Summary: Hydrological periods can affect the water quality of lentic ecosystems, and this study evaluates the ecological status of lentic ecosystems in the western Mediterranean basin during rainy and dry periods using various diatom metrics. The results show that different ecological regional diatom indices have different applicability in assessing the ecological conditions of these ecosystems.

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: Lakes in the northeast United States are recovering from acidification, but the effects of climate change on species assemblages are uncertain. This study examined the impact of past acidification on Beaver Pond in Vermont, USA, using long-term water chemistry analysis and paleolimnological analysis. The results suggest that Beaver Pond is experiencing chemical and biological recovery from acid deposition, although the diatom communities in the recovery period differ from those before acidification.

Summary: This study used a historical ecology approach to reconstruct the ecological successions of a Mediterranean peat-bog over the past 4 millennia. It found that the superimposition of pastoral disturbances and river incision exacerbated the ecosystem's sensitivity to climate change. The study suggests that long-term dynamics should be considered before engaging in strict conservation actions.

Summary: The scarcity of research on lake ecosystem responses to large-scale climate oscillations in NE China limits our ability to inform conservation practices and policies in the context of recent global warming. A high-resolution sedimentary diatom record from Lake Moon reveals significant shifts in diatom dominance corresponding to fluctuations in the climate regime since the last deglaciation, indicating the overarching control of climate change on aquatic ecosystem changes in the mountain regions of NE China.

Summary: Paleoecological studies have provided important data on the feeding behavior and living environments of extinct taxa. A recent study analyzed the fish assemblage of the Acu Formation through a multiproxy approach and concluded that the fish were mainly generalists in terms of feeding behavior and swimming adaptations. Comparisons with similar age units in Western Gondwana suggest a significant paleontological potential for the Acu Formation. The study highlights the importance of multiproxy approaches in paleoecological studies and the need for a major review on ecological terminology.

The method is applied to benthic macroinvertebrate communities in the Rance estuary, identifying potential gateways for environmental variability. This novel framework could be used for more comprehensive identification of environmental drivers of community change, including gateway community members and cascades of environmentally driven change through community structure.

Summary: This study investigates the identification of climatic refugia in the Pyrenees mountain range based on the evolutionary distinctiveness (ED) of plant communities. The results show that forests and high altitude wetlands have higher cED, indicating their potential role as mobile refugia and more permanent microrefugia respectively. These habitats hold important evolutionary potential to cope with climate change and should be integrated into conservation agendas.

Six significant humid periods were identified and found to correlate with other Mediterranean paleohydrological records. The findings suggest similar climatic factors and North Atlantic ocean-atmospheric dynamics as the main drivers of both the Mediterranean and West Africa during high seasonality.

Summary: This study investigated the drivers of vegetation change in the Cantabrian Range during the Late Holocene. The results showed that past land use and climate change have played a significant role in shaping the high-elevation vegetation, particularly the decline of pine and expansion of scrubland. Future management should focus on preserving and restoring mountain scrubland and meadows, as well as reestablishing ancient pine-birch woodlands.

Summary: This study presents the first continuous pollen record for the Iberian Pyrenees during the Late Glacial-Early Holocene period. The aims of the study were to establish a chronostratigraphic correlation framework, understand the relationships between vegetation shifts, climatic changes, and fire, and obtain a regional picture of the vegetation during this period. The results revealed four vegetation types and showed wetter climates during the Younger Dryas, challenging previous assumptions of arid conditions. The study also found an increase in fire incidence during the Early Holocene. The findings were compared with other pollen records in the Pyrenean range and surrounding lowlands.

Summary: The study examines changes in seasonal temperature and moisture across the Iberian Peninsula over the past 12,000 years. While there is an increasing trend in winter temperature, summer temperatures do not show the expected decrease in response to insolation forcing. Instead, summer temperature is closely correlated with plant-available moisture, which declines through the Holocene. The study also finds that the west-east gradient in moisture was less pronounced during the mid-Holocene, suggesting the importance of atmospheric circulation changes in determining the regional climate.

Summary: Hypersaline lakes are sensitive environments that are threatened by human activities and climate change. They can provide valuable information about past environmental conditions. The study of sediment cores from a hypersaline lake in the Iberian Peninsula reveals changes in the lake's geochemical processes and paleoenvironment over the last few centuries. These changes are influenced by farming and irrigation practices, as well as increased organic productivity. The research highlights the importance of using multiple sediment cores to accurately reconstruct the paleoenvironment of saline lakes.

This study presents new dating results from the Niqingqu Valley in the Tibetan Plateau, showing multiple glacial activities prior to the Penultimate Glacial Maximum. The findings suggest that low atmospheric CO2 content and reduced summer solar insolation/high summer-monsoon precipitation played a role in these glacial fluctuations.

Summary: Through sediment records from Lake Nanyi in the lower Yangtze, we found that anthropogenic fire activity played a dominant role in the region, and the temporal pattern of fire activity was asynchronous from east to west. Archaeological evidence suggests an inverse relationship between agricultural and population levels and fire intensity during the mid-Holocene, with fire intensity being influenced by the diversity of landscape types associated with pre-historic subsistence patterns. Overall, changes in regional water-level delayed the transition from hunting-gathering to agriculture in the lower Yangtze region.

Summary: This paper argues that sessile barnacles are an excellent proxy for palaeoenvironmental reconstructions. The shells of barnacles consist of diagenetically stable low-magnesium calcite and record short-term variations. Analyses of several Western Mediterranean barnacle-rich deposits demonstrate the utility of barnacles as proxies for water depth, distance from the coastline, and hydrodynamic conditions. Moreover, the stable isotope ratios of barnacle shells can provide detailed palaeoenvironmental information.

Summary: The Late Ordovician mass extinction occurred during an ice age, with maximum ice coverage and a substantial drop in global sea level. This led to the exposure or shallowing of shallow tropical shelf environments. The study suggests that the burial rate of nutrient phosphorus (P) on shelves was minimal during this glacial period, leading to excess bioavailable P entering the open ocean and stimulating phytoplankton production, which in turn lowered oxygen concentrations.
