Summary: The Milk and St. Mary Rivers are international waterways that face challenges in water resource management due to stakeholder interests and limited understanding of long-term streamflow variability. The study found that winter temperatures have a significant impact on streamflow variability in the lower reaches of the Milk River, leading to severe drought conditions in the prairies in the 2000s. Tree-ring chronologies also revealed sub-basin specific drought risks and the potential for future water supply management challenges caused by prolonged droughts and warmer temperatures.

Summary: Understanding how anthropogenic droughts impact socio-hydrological systems is crucial for studying system resilience, with a focus on Lake Urmia in Iran facing similar issues as the Aral Sea. The study identifies a paradoxical phenomenon where increasing soil salinity hasn't significantly affected vegetation cover in the basin.

Summary: This study observed and analyzed the changes in waterbird communities at Lake Ngami in Botswana, finding that while there were variations in abundance and structure during transitions, there was no obvious simplification. Rapid shifts in functional composition were seen during transitional stages, with winners and losers occurring within foraging guilds.

Summary: The study of Searles Lake in California during the late Pleistocene/Holocene period has revealed the geochemical and paleoclimate conditions that led to the formation of specific mineral phases in the sediment. Model simulations suggest that cycles of partial evaporation and dilution strongly influence long-term brine evolution by amassing certain species.

Summary: This study investigates the existence of paleolakes in the isolated watersheds of the Mojave Desert, confirming their presence and the active nature of basin margins. The research shows that evidence of past high-lake stands is often buried but preserved by geomorphic processes, and suggests that the basin margin is where evidence of pluvial lakes should be sought. Some Holocene paleolakes in the Ivanpah basin seem to have persisted for decades to centuries.

Summary: In this study, two hybrid alkaline cements (HAC) based on Portland clinker, GGBFS, fly ash and sodium sulfate were tested alongside an alkali-activated GGBFS/fly ash blend and a Portland cement paste. These materials were exposed to a saturated saline solution for 70 days to investigate their resistance against combined chemical attack. The results showed that the resistance of HAC against corrosion in the saline solution increased with the fraction of Portland clinker, and the presence of portlandite maintaining pH above 10 was a major factor.

Summary: This study examines the lake-level variations in the Dead Sea during the Holocene and finds that the early and late Holocene were wetter, while the middle Holocene was relatively dry. This pattern is consistent with distillation records from Levant speleothem caves. The predicted future drying in the Levant is similar in magnitude to the natural hydroclimate variability, highlighting the importance of assessing whether anthropogenic drying is in or out-of-phase with natural climate variability.

Summary: The sulphur cycle plays a crucial role in the distribution of nutrients, but its characteristics in saline endorheic lakes still require further exploration. A study of Gallocanta Lake in Spain reveals that the geological background constrains sulphur cycling, resulting in high sulphate concentrations in the lake bed. The occurrence of bacterial sulphate reduction near the water-sediment interface prevents methane production and release, which is beneficial in the context of global warming.

Summary: Increasing a city's food supply chain diversity can boost its resistance to mild to moderate food shocks by up to 15%. An intensity-duration-frequency model linking food shock risk to supply chain diversity has been developed, based on empirical data from metropolitan areas in the USA during years of moderate to severe droughts. This model explains a city's resistance to food shocks as a function of its food supply chain's Shannon diversity and provides a simple and operationally useful tool for policymakers to improve resilience to food supply shocks.

Summary: Microbial carbon fixation in saline lakes is a crucial part of the global lacustrine carbon budget, but its rates and influencing factors are not fully understood. This study examined the in situ microbial carbon uptake rates in Qinghai Lake using isotopic labeling and found that light-dependent rates were higher than dark rates. Photoautotrophic prokaryotes and algae were identified as major contributors to light-dependent carbon fixation. Nutrient levels, specifically dissolved inorganic carbon, significantly influenced microbial carbon uptake rates. Overall, microbial light-dependent and dark carbon fixation processes play a key role in carbon sequestration in saline lake water, highlighting the need for further research on microbial carbon fixation in the context of climate change.

Summary: Studying the impact of earthquake-induced disturbances on lake microbial communities using sediment DNA analysis revealed significant differences in composition and function, indicating a lack of resilience to large-scale natural pulse disturbances. This research highlights the destabilizing effect that large pulse disturbances, such as increased sediment inputs, can have on lake ecosystem processes.

Summary: This study compares paleohydrologic variability over the past 2000 years in two regions of California - the Sierra Nevada region and southern California region. Both regions exhibit significant and reproducible evidence of multi-decadal wet/dry intervals that are synchronized between the two regions. The duration of individual cycles averages around 130 years but has been closer to 90-100 years in the last 500 years and over 200 years 1500-2000 years ago. This pattern of cyclical variability is still ongoing and appears to be related to the intrinsic regional climate variability of the Pacific/California margin.

Summary: The study found that microbial diversity in Lake Magic is influenced by factors such as carbon, temperature, pH, and salt concentrations, with fungal diversity decreasing as environmental conditions become more extreme while bacterial diversity remains dynamic and dominant. Acid and salt tolerant species were observed to increase in sediment, contributing to buffering the external environment and providing a safe haven for microbes in the face of extreme conditions during evapo-concentration and desiccation stages.

Summary: This study examines the importance of climate change, specifically drought, in the Maya region by analyzing a 6600-year paleolimnological record from Yaal Chac, a carbonate lake in the Yucatan Peninsula. The findings reveal that Yaal Chac responded differently to climate variability in the mid Holocene and late Holocene. In the mid Holocene, the lake was stable but possibly influenced by increased climatic seasonality. In the late Holocene, there was more coherence between Yaal Chac and other regional records, indicating a more variable climate. The record also shows evidence of drying in the 14th to 19th centuries CE, consistent with other proxy and historical records.

Summary: This study investigated the fate of nano-ZnS in soils with different properties using a combination of techniques, showing the crucial role of soil properties and the faster dissolution of nano-ZnS in clayey soil. Despite the slower dissolution rate of nano-ZnS in sandy soil, the availability of Zn was found to be higher due to the ions released, highlighting the importance of considering released ions in addition to nanoparticle dissolution when studying the fate of nanoparticles in soil.
