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,

Microplastics in the menu of Mediterranean zooplankton: Insights from the feeding response of the calanoid copepod Centropages typicus

Marine Ecology, EarlyView., 2023
Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

From Headwaters to the Sea: The Journey of Creating an Immersive Museum Exhibit

Limnology and Oceanography Bulletin, EarlyView.
Abstract We describe the multi‐year journey of a group of researchers co‐creating a museum exhibit with the Biosphère an environmental museum of the City of Montréal. The collaboration resulted in an immersive experience where visitors can dive into an aquatic continuum and learn about function, ecology, chemistry, and the roles of the various aquatic ...

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

Marine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...

Phytoplankton periodicity: its motivation, mechanisms and manipulation [PDF]

, 1982
This review summarizes some recent work to find a generalized explanation of phytoplankton periodicity in lakes. Much of the observational and experimental evidence is drawn from work centred on the large enclosures (Lund Tubes) installed in Blelham Tarn,

Revisiting the distribution and total amount of nitrogen fixation across the Kuroshio

Limnology and Oceanography Letters, EarlyView.
Abstract The Kuroshio Current, a western boundary current in the North Pacific Ocean, is regarded as a hotspot of nitrogen fixation that drives marine primary productivity and biogeochemical cycles. However, this assumption is based on limited, spatiotemporally biased data.

Efficient cobalamin uptake and cycling contribute to the lack of cobalamins in the surface cobalt‐binding ligand pool in the North Pacific

Limnology and Oceanography Letters, EarlyView.
Abstract Cobalt is a central component of cobalamins, which are nutrients essential for various metabolic processes in marine organisms. Dissolved cobalt in seawater is mostly bound to organic ligands, and the prevailing assumption to date is that these ligands are cobalamin‐related compounds, yet the identity and impact of these ligands on cobalt ...

Environmental transcriptomics under heat stress: Can environmental RNA reveal changes in gene expression of aquatic organisms?

Molecular Ecology, EarlyView., 2023
Abstract To safeguard biodiversity in a changing climate, taxonomic information about species turnover and insights into the health of organisms are required. Environmental DNA approaches are increasingly used for species identification, but cannot provide functional insights.

Climate change and underwater light: Large‐scale changes in ultraviolet radiation transparency associated with intensifying wet–dry cycles

Limnology and Oceanography Letters, EarlyView.
Abstract Ultraviolet radiation (UV) is the most energetic waveband of incident solar radiation and has wide‐ranging effects in the aquatic environment. Our analysis of an 18‐year record of underwater irradiance and related limnological variables in sub‐alpine, ultra‐oligotrophic Lake Tahoe revealed orders of magnitude changes in UV transparency ...

Aquatic heatwaves increase surface chlorophyll concentrations in experimental and reference lakes

Limnology and Oceanography Letters, EarlyView.
Abstract Aquatic heatwaves are increasing in frequency, intensity, and duration worldwide. While increases in mean water temperatures are linked to enhanced phytoplankton biomass, it is unclear how heatwaves alter phytoplankton dynamics in lakes at an ecosystem scale.
