TL;DR: It is found that in Midwest and Northeast North America, most urban lakes and rural lakes that are surrounded by >1% impervious land cover show increasing chloride trends, and many lakes will exceed the aquatic life threshold criterion for chronic chloride exposure in the next 50 y if current trends continue.

TL;DR: Multivariate partial least squares regression showed that DOM composition was related to differences in human impact across freshwater ecosystems, and urban/developed watersheds with higher human population densities had a unique DOM composition with a clear anthropogenic influence that was distinct from DOM composition in natural land cover and/or agricultural watersheds.

TL;DR: In this paper, the authors explore evidence of cyanobacterial blooms in oligotrophic freshwater systems and provide explanations for those occurrences, and show that through their unique physiological adaptations, cyanobacteria are able to thrive under a wide range of environmental conditions, including low-nutrient waterbodies.

TL;DR: In this paper, the authors hypothesized that DOM quantity and composition should be better predicted by land cover in aquatic habitats with allochthonous DOM and related more strongly to nutrients in aquatic environments with autochthonal DOM.

TL;DR: In this paper, a simple, dynamic mass balance model for organic carbon (OC) was developed and applied to a set of five lakes and found that long-term (>10-year) lake OC dynamics were predominantly driven by allochthonous loads in four of the five lakes, highlighting the importance of terrestrially derived OC in northern lake ecosystems.
