Abstract Eutrophication in the Baltic Sea has caused an imbalance in the inorganic nitrogen (N) to phosphorus (P) ratio, leaving excess phosphate (PO4) after the phytoplankton spring bloom that terminates after N depletion. Using monitoring data, we demonstrated that the PO4 concentration has continued to increase in the outermost Gulf of Finland ...

Abstract In the context of global change, marine organisms are subjected not only to gradual changes in abiotic parameters, but also to an increasing number of extreme events, such as heatwaves. However, we still know little about the influence of heatwaves on the structure of marine communities, and experimental studies are needed to test the impact ...

Microalgae-based biodiesel is increasingly recognized as an alternative to crop-based biodiesel. In this study, 10 local strains of dinoflagellates collected from Hong Kong waters, including a monoculture and field sample of Scrippsiella sp.

P. donghaiense is one of the most common dinoflagellate species that form harmful algal blooms, which frequently cause serious ecological pollution and pose health hazards to humans and other animals.

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 ...

Abstract Drought events are typically studied as a single stressor. However, multiple environmental variables are altered under drought conditions, including water level and daily temperature variation. Here, we experimentally manipulated both variables in 16 outdoor mesocosms to disentangle how they impact freshwater zooplankton communities.

An unprecedented coastwide toxic algal bloom linked to anomalous ocean conditions
A coastwide bloom of the toxigenic diatom Pseudo‐nitzschia in spring 2015 resulted in the largest recorded outbreak of the neurotoxin, domoic acid, along the North American west coast. Elevated toxins were measured in numerous stranded marine mammals and

Abstract Marine heatwaves are expected to become more frequent and intense due to global climate change, potentially impacting plankton communities. In the present study, the effects of a simulated short‐term warming event on the structure and functioning of coastal plankton communities were investigated during a mesocosm experiment conducted with ...

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