Summary: This study investigated the mechanisms underlying a whiting event during the early summer of 2019 in Lake Geneva. The event started during a snowmelt period in the catchment at the Rhone River delta before spreading along the lake's northern shore and covering vast areas of its deeper basin. The development of the event depended upon the thermal stratification of the water column and the existence of a physically stable metalimnion.

Summary: The tradition of stocking whitefish in European lakes, including Lake Constance, is being questioned due to the decreasing success rate and changing ecosystems. The last evaluation in 2003 showed declining effects, and recent experiments suggest that stocking is no longer cost-effective. Factors that previously influenced recruitment, such as water temperature, may not apply anymore.

Summary: This study assessed the biological characteristics of Lake Whitefish within inland lakes in Ontario and tested whether there were changes in their relative abundance over 15 years. The results showed that the relative abundance of Lake Whitefish varied among different fisheries management zones but remained consistent within and across cycles. Whitefish abundance was higher in lakes with lower diversity in large-bodied fish species, greater water transparency, depth, and hypolimnetic dissolved oxygen levels. The study also found that the growth potential, age, and maturity of Lake Whitefish were similar between sexes. The overall survival rate for populations with at least 50 sampled Lake Whitefish was 87%. This indicates limited exploitation of Lake Whitefish populations in Ontario's inland lakes.

Summary: This study investigated the microbiome composition and condition of lake whitefish and cisco in high latitude regions. The results showed that the intestine microbiomes of lake whitefish were more susceptible to environmental stress and potential dysbiosis compared to cisco. Lake whitefish had lower condition in the ocean habitat, while cisco had similar condition across different seasonal habitats. These findings have important implications for fisheries and aquaculture management as well as the livelihood and economic interests of indigenous peoples.

Summary: In this study, the total mercury (THg) content and mercury isotope composition in sediments in the Lianxi River, Zijiang River, and South Dongting Lake were investigated to identify and quantify multiple mercury sources and evaluate mercury environmental processes. The results showed that the THg content, delta Hg-202, and Delta Hg-199 values in the sediments varied from 48.22 to 4284.32 μg/kg, 1.33 to 0.04‰, and 0.25 to 0.03‰, respectively. The sediments from the Lianxi River, Zijiang River, and South Dongting Lake exhibited distinct mercury isotope characteristics, indicating significant variations in dominant mercury sources in these regions. Source apportionment based on MixSIAR revealed that mercury in sediments mainly originated from industrial activities, with non-ferrous metal smelting being the dominant industrial mercury contributor in the Lianxi River. Compared to the Lianxi River, the relative contribution of mercury from industrial activities significantly decreased, while the relative contributions of mercury from background releases significantly increased in the Zijiang River and South Dongting Lake.

Summary: Mountain lakes are most affected by climate change, with Lake Campo in the Adamello Mountains, Italy showing significant water temperature variability over the years, especially in the warmest year of 2015. Phytoplankton and zooplankton data from the lake displayed seasonal differences, rather than year-to-year variations. The presence of certain species and changes in water parameters reflected the impact of particularly warm conditions, providing insights into the changes mountain lakes undergo through time.

Summary: Isoprenoidal glycerol dialkyl glycerol tetraether (isoGDGT) lipids are mainly derived from archaea in the water column of Lake Lugano, Switzerland. The concentration of isoGDGTs, particularly Crenarchaeol, is higher in deeper waters below the thermocline. The distribution of isoGDGTs in surface sediments indicates downward transport from the water between the thermocline and the anoxic hypolimnion. The composition of isoGDGTs in surface sediments of other (peri-)alpine lakes varies based on lake size.

Summary: Zooplankton can spend winter actively under lake ice, with only a fraction contributing to an active food web due to limited and unrewarding feeding opportunities. Zooplankton fatty acids under ice mostly come from previously accumulated fat storage, with little contribution from under-ice seston assimilation. The food web under lake ice is supported by mixotrophic phytoplankton, resulting in few trophic linkages and low connectance in the planktonic community.

Summary: Over the past decade, there has been a significant increase in studies examining the presence and effects of microplastics in the environment. These studies have shown that microplastics constitute a widespread pollution that affects all environmental compartments. They have also demonstrated that when microplastics are associated with persistent organic pollutants, they can have deleterious effects. This article focuses on the sorption and transport of persistent organic pollutants by microplastics in the aquatic environment and the possible toxic effects that result from this interaction.

Summary: By studying high-temporal resolution time series of dissolved oxygen concentration and temperature in 14 mountain lakes, it was found that the duration of bottom hypoxia under ice varies greatly among lakes and years. The variability of hypoxia duration is primarily explained by changes in the decay rate of dissolved oxygen above the lake bottom, which is linked to physical controls such as deep-water warming. The study also showed that the summer light climate is a key driver of the dissolved oxygen decay rate and hypoxia duration under the ice.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
