Salting our freshwater lakes.
The highest densities of lakes on Earth are in north temperate ecosystems, where increasing urbanization and associated chloride runoff can salinize freshwaters and threaten lake water quality and the many ecosystem services lakes provide. However, the extent to which lake salinity may be changing at broad spatial scales remains unknown, leading us to first identify spatial patterns and then in...

متن کاملBacterial Dormancy Is More Prevalent in Freshwater than Hypersaline Lakes
Bacteria employ a diverse array of strategies to survive under extreme environmental conditions but maintaining these adaptations comes at an energetic cost. If energy reserves drop too low, extremophiles may enter a dormant state to persist. We estimated bacterial dormancy and identified the environmental variables influencing our activity proxy in 10 hypersaline and freshwater lakes across th...
متن کاملMicrobial reduction and oxidation of mercury in freshwater lakes.
The evasion of elemental mercury represents a significant pathway for reducing the level of this potentially toxic material in aquatic ecosystems. The evasion rate is controlled by the concentration of dissolved gaseous mercury (DGM) across the air-water interface, water, and air temperature as well as wind speed. Here we investigate the role of microbial mercury oxidation and reduction in regu...
متن کاملIron Biogeochemistry and Its Environmental Impacts in Freshwater Lakes
Iron is an essential element for almost all living species. Its environmental impacts on physiology and ecology of aquatic organisms are always the focus of limnology and oceanography. To gain insight into iron biogeochemistry and its environmental impacts in freshwater lakes, we collected and reviewed numerous studies on iron in combination with our own work. Our review reports iron sources, i...
