Summary: Lakes are important in the global carbon cycle, but few complete budgets have been done. This study estimated the OC budget for Lough Feeagh in Ireland and found that lakes in temperate, humic systems are important in the processing and fate of OC.

Summary: This study examines the nutrient dynamics in Flathead Lake over a period of 38 years. Despite low nutrient levels, the lake maintained high nitrogen to phosphorus ratios. This stoichiometric imbalance led to phosphorus limitation in phytoplankton growth and affected the nutrient cycling in the entire ecosystem.

Summary: The study found that under-ice biological activity was not as low as previously assumed, with under-ice respiration significantly higher than summer respiration. Ice formation and melting periods were important contributors to annual metabolism estimates, resulting in negative net ecosystem production during winter, contrasting with positive values in spring and summer. Including winter metabolism estimates changed annual net ecosystem production from autotrophy to heterotrophy, highlighting the importance of year-round sampling for accurate assessment of carbon cycling in lakes.

Summary: This study characterized the microbiome of the crater lake of the El Chichón volcano in Mexico, revealing taxonomic and functional diversity of representative Archaea and Bacteria phyla. Metabolic interactions between prokaryotes in this multi-extreme environment were identified, contributing to the understanding of microbial metabolism under extreme conditions. This research provides potential knowledge that can be applied to biotechnological processes and evolutionary studies.

Summary: This study conducted an experiment in Raunefjord, Norway involving the simulation of extreme pCO2 levels in coastal regions, and found that high CO2 conditions significantly impacted the structure of plankton communities, leading to a substantial reorganization of the planktonic food web.

Summary: Ammonium dynamics in the oligotrophic South China Sea were found to be influenced by factors such as Kuroshio intrusion, leading to considerable variation in NH4+ concentrations between 2014 and 2016. Stations affected by the Kuroshio showed higher NH4+ concentrations and lower NO3- inventories. Two patterns in vertical NH4+ distributions were observed, with profiles showing subsurface NH4+ maximum and profiles with generally uniform NH4+ concentrations.

Summary: This study presents a novel approach to identifying improvement goals of interacting ecosystem services by using the method of production possibility frontier (PPF) and considering their context dependency. The results show that the supply efficiency of ecosystem services in the Dongting Lake Basin is significantly influenced by the farmland area ratio and elevation. The sub-watersheds with farmland area ratio below the inflection point, mainly located around poor counties, pose a great challenge for improving ecosystem services with trade-off relationship.

Summary: Lake sediment plays a crucial role in phosphorus storage and release. The study on Skaneateles Lake reveals that the redox processes of Fe-bound and Mn-bound phosphorus are the primary controls for its storage and release. The concentrations of phosphorus in sediment are influenced by water depth and the presence of calcium.

Summary: Research shows that fine-scale frontal disturbances impact phytoplankton assemblages and carbon cycling, with shorter-duration and higher-intensity disturbances favoring the growth of large phytoplankton and enhancing carbon export efficiency, while longer-duration and higher-intensity disturbances lead to reduced new production due to a decoupling between physical changes and biological responses.

Summary: Mulching rain-fed farmland ecosystems can affect soil organic carbon and microbial metabolic limitations. The type of mulch is related to soil enzyme activities, while soil nutrients, pH, and temperature influence the C and P limitations of soil microorganisms.

Summary: Climate change affects both lakes and their catchments, leading to changes in runoff patterns and biogeochemical dynamics. An integrated model combining catchment and lake models is rare but crucial. This study predicts the future climate, catchment loads, and lake water quality for Lake Erken, Sweden using different climate models and future scenarios. The findings suggest increased water inflow to the lake, changes in soil and nutrient inputs in the catchment, and elevated water temperatures and nutrient levels in the lake. The coupled catchment-lake model enables predictions of future biogeochemical conditions and their link to land use and eutrophication.

Summary: This study used high-frequency measurements of dissolved O2 and CO2 concentrations to estimate the potential contribution of stream metabolism to the CO2 evasion flux in a tropical lowland headwater stream. The results showed that the stream was heterotrophic all year round, with positive net ecosystem productivity (NEP) values. Despite seasonal changes, the CO2 excess was likely transported downstream and emitted to the atmosphere.

Summary: The study analyzed the effects of 25 extreme wind storms on a shallow lake ecosystem and found that antecedent lake conditions were more important than storm characteristics in explaining variation in lake ecosystem resistance and resilience. Factors such as duration, mean precipitation, shear stress intensity, and time between storms were found to influence the resistance and resilience of lake ecosystems.
