Inundation of different river bank heights influences organic matter concentrations and zooplankton abundance

Limnology and Oceanography, EarlyView.
Abstract Regulation and water extraction change flow regimes in lowland rivers, affecting ecosystem functions and wetting patterns of riverbanks. River connectivity to lateral environments is crucial for organic matter cycling and the life cycles of diapausing microinvertebrates. While extreme hydraulic periods (floods and cease‐flow) are well‐studied,

Prolonged low flows and non‐native fish operate additively to alter insect emergence in mountain streams

Limnology and Oceanography, EarlyView.
Abstract Climate‐induced flow alteration is decreasing snowpack and advancing snowmelt, subjecting mountain streams to longer low‐flow periods. Yet, anticipating how stream ecosystems respond to prolonged low flows remains challenging because distinct trophic levels can respond differently, and non‐native predators can dampen or amplify responses. Here,

Light and temperature as triggers for surface filamentous green algal blooms in shallow freshwater systems

Limnology and Oceanography, EarlyView.
Abstract Blooms of filamentous green algae (FGA) form dense mats at the surface of shallow freshwaters and have multiple negative impacts on aquatic ecosystem functions, services, and aesthetics. Although nutrient enrichment in freshwaters is a primary driver of excessive FGA growth, much less is known about other abiotic factors controlling bloom ...

Incorporation of diazotrophically fixed nitrogen by juvenile fish in a coastal sea

Limnology and Oceanography, EarlyView.
Abstract Nitrogen‐fixing cyanobacterial blooms worldwide have been shown to support production in primary consumers such as zooplankton and benthic invertebrates, but there have been few estimates of how much of the cyanobacterial nitrogen ends up in secondary consumers, such as fish.

Effects of oligotrophication on fish growth: Insights from a mesocosm experiment

Limnology and Oceanography, EarlyView.
Abstract Human activities can frequently affect aquatic ecosystems in irreversible ways, with flow regulation and water quality being major concerns. Dams can promote the retention of sediments and nutrients, increase water transparency, and reduce primary productivity, all of which characterize the oligotrophication process.

Urban heterogeneity drives dissolved organic matter sources, transport, and transformation from local to macro scales

Limnology and Oceanography, EarlyView.
Abstract Urbanization reshapes dissolved organic matter (DOM) sources, transport, and transformations through changes in vegetation, hydrology, and management of waste and water. Yet the impacts of urbanization on DOM are variable within and among cities.
