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.

Seasonal patterns in B‐vitamins and cobalamin co‐limitation in the Northwest Atlantic

Limnology and Oceanography, EarlyView.
Abstract B‐vitamins are important co‐enzymes that have long been hypothesized to play key roles in marine ecosystems. However, environmental measurements remain scarce, which limits our understanding of their potential impact. Here, we present mass spectrometry‐based measurements of B‐vitamins (B1, B2, B3, B5, B6, B12) and related vitamers along a ...

Iron physiology and metabolism of model phytoplankton taxa in a western boundary continental shelf ecosystem

Limnology and Oceanography, EarlyView.
Abstract Continental shelf ecosystems support diverse phytoplankton communities that contribute to global primary productivity. Iron is an important micronutrient controlling the growth of marine phytoplankton, but its role in influencing phytoplankton ecophysiology in western boundary continental shelf ecosystems is understudied.

Discharge and nutrients interact to determine trophic structure in a wetland: Evidence from a landscape‐scale manipulation

Limnology and Oceanography, EarlyView.
Abstract Identifying drivers of consumer biomass patterns and community structure is complex for managed freshwater ecosystems that are sensitive to nutrients and drought. In the Florida Everglades, flow restoration is expected to reintroduce discharge across an expansive wetland, yet most research on consumers has focused on water depth and dry ...

Unique thermal mixing patterns in Lake Ontario revealed by novel year‐round observations of thermal stratification

Limnology and Oceanography, EarlyView.
Abstract Year‐round records of thermal stratification in the Great Lakes are rare, and there are few observations of thermal stratification during winter. In this paper, we analyze temperature data from 13 temperature logger chains and from over 130 benthic acoustic receivers that were deployed across Lake Ontario for 2 yr.

Interactive effects of stoichiometry and environmental variability regulate cyanobacteria toxicity in two eutrophic bays

Limnology and Oceanography, EarlyView.
Abstract Cyanobacteria blooms are a leading threat to water quality globally. Despite this, the timing and frequency of toxin production associated with harmful blooms are not well understood. Here we explore cyanobacteria bloom dynamics and cyanotoxin production in two heavily instrumented shallow, eutrophic bays of Lake Champlain through the lens of ...

Wind wave climate in the Eastern Mediterranean Sea over the past century from visual ship‐based observations

Limnology and Oceanography, EarlyView.
Abstract A comprehensive analysis of wind wave climate in the Eastern Mediterranean Sea over the past century (1924–2023) is presented. Visual wave observations conducted in the frame of the Voluntary Observing Ship (VOS) program lay the foundation for the performed analysis.

Temperature and light drive physiological and transcriptional responses, modulating infection outcomes in a freshwater diatom–chytrid system

Limnology and Oceanography, EarlyView.
Abstract Stephanodiscus binderanus is a bloom‐forming diatom abundant in winter and persisting into spring in the Laurentian Great Lakes. Climate change impacts these blooms by altering ice cover, turbidity, light penetration, and water temperature.

Bridging the gap between field and lab: Applicability and performance of the Sylt mesocosms facility to simulate climate change scenarios on intertidal benthic communities

Limnology and Oceanography, EarlyView.
Abstract Climate change significantly threatens coastal ecosystems, making effective conservation strategies essential and reliant on accurate data. This study employed the Sylt mesocosms facility to examine how coastal marine communities respond to both individual and combined stressors.
