Abstract High‐latitude systems are warming faster than the global average, altering the rates of silicon (Si) mobilization from terrestrial to aquatic systems. Dissolved Si (DSi) concentration and its ratio with other nutrients exert strong controls on algae blooms in fresh and marine …

Climate change is reshaping lake ecosystems globally, notably through alterations to thermal stratification and mixing regimes. This synthesis describes "anoximixis," the complete mixing of a stratified waterbody with anoxic bottom waters, and reviews the biogeochemical and ecological implications of anoximixis outside of …

Abstract Riverine dissolved silicon (DSi) dynamics reflect integrated geologic, hydrologic, climatic, and ecological controls. We compiled annual DSi data for 337 rivers across four continents and trained interpretable machine‐learning models to predict concentrations and yields from 28 watershed variables. Both models reproduced …

Abstract Riverine silicon (Si) plays a vital role in governing primary production, water quality, and carbon cycling. Climate and land cover change have altered how dissolved Si (DSi) is processed on land, transported to rivers, and cycled through aquatic ecosystems. The Global …

Abstract Harmful blooms of cyanobacteria (cyanoHABs) are increasingly reported in remote and low-nutrient lakes, prompting a paradigm shift in our understanding of the drivers of cyanoHABs and a need to study factors beyond watershed nutrient inputs. In this study, we examined eight …

River damming disturbs the transport and fate of nutrients, which alters biogeochemical cycling within reservoirs and alters the flux of nutrients downstream. In reservoirs, silicon (Si) is retained in larger proportions relative to nitrogen (N) and phosphorus (P) which can reduce dissolved …

Nitrogen (N) fertilizer enhances crop production, but field runoff impacts water quality in adjacent freshwaters. Planting winter cover crops reduces nitrate-N losses during the fallow period, but less is known about impacts on ammonium-N. From 2016–2023, we sampled biweekly from the Shatto …

Abstract The seasonal behavior of fluvial dissolved silica (DSi) concentrations, termed DSi regime , mediates the timing of DSi delivery to downstream waters and thus governs river biogeochemical function and aquatic community condition. Previous work identified five distinct DSi regimes across rivers …

The composition and concentration of dissolved organic matter (DOM) in freshwater ecosystems are influenced by the abundance and diversity of phytoplankton, which are, in turn, affected by nutrient availability. The interactions among DOM, phytoplankton, and nutrients are not fully understood, particularly regarding …

Abstract Fluvial silicon (Si) plays a critical role in controlling primary production, water quality, and carbon sequestration through supporting freshwater and marine diatom communities. Geological, biogeochemical, and hydrological processes, as well as climate and land use, dictate the amount of Si exported …
