Diatom biosilica as a supplementary cementitious material

npj Materials Sustainability
The use of supplementary cementitious materials (SCMs) is a key method used to reduce the embodied carbon of cement-based materials. Uncertainty in traditional SCM markets has led to increased interest in alternative, natural SCM materials. In this work,

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

Fisheries Oceanography, EarlyView.
ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food webs, focusing on the Gulf of Alaska (GoA) during late winter of 2019.

Marine heatwaves shape size‐dependent thermal exposure, habitat use and marine residency in Arctic char (Salvelinus alpinus)

Journal of Fish Biology, EarlyView.
Abstract Marine heatwaves (MHWs) are increasing in high‐latitude oceans, yet behavioural responses of anadromous fishes to these potential stressors during short marine feeding seasons remain poorly understood. We combined acoustic telemetry (internal temperature and depth) with satellite‐derived sea surface temperature data to quantify Arctic char ...

Auxin response and PIN‐mediated transport in chlorophyte algae

Journal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Chloroplast and mitochondrial genomes of Sphaerosorus coelastroides Pascher (Xanthophyceae) from Central Appalachia, Clinch River, Virginia, United States

Journal of Phycology, EarlyView.
Abstract This report describes the isolation and culture of Sphaerosorus coelastroides from the plankton of a freshwater river in the central Appalachian mountain chain. This alga was first observed in a dry freshwater riverbed in Central Europe in 1908 and, since then, has been included in Xanthophyceae surveys from nearly all continents with ...

Dinoflagellate responses to nutrients and mangrove leaf organic matter in the bioluminescent Mangrove Lagoon, St. Croix, U.S. Virgin Islands

Journal of Phycology, EarlyView.
Abstract Bioluminescent bays (biobays) are uncommon coastal ecosystems featuring dense populations of dinoflagellates, often found in mangrove‐ringed lagoons with long water retention times and high organic matter (OM) levels. Although mangroves are associated with high dinoflagellate abundance, it remains uncertain how inorganic nutrients compare with

Holdfast adhesion in the kelp Alaria marginata: Cell wall polysaccharides and phenolics

Journal of Phycology, EarlyView.
Abstract Adhesion is a critical process in the survival of seaweeds, especially in wave‐swept environments. Kelp (Laminariales) sporophytes secrete adhesives from specialized rhizoid cells to anchor themselves to the substrate and withstand immense forces applied by waves.

Impact of the invasive diatom species Cymbella janischii on riverine microbial biofilm communities and a potential role of bacterially produced zeatin

Journal of Phycology, EarlyView.
Abstract The diatom Cymbella janischii is an invasive species in Japan, causing nuisance blooms by forming thick mats in rivers. To date, there are no documented studies on the microbiome associations in C. janischii mats or the processes that drive bloom formation.

Identification and functional analysis of class 3 lipases associated with triacylglycerol metabolism in Nannochloropsis oceanica (Eustigmatophyceae)

Journal of Phycology, EarlyView.
Abstract Microalgae accumulate triacylglycerols (TAGs) as storage lipids in response to nutrient limitation, yet the mechanisms governing TAG turnover remain incompletely understood. In the oleaginous microalga Nannochloropsis oceanica, functional studies of TAG degradation have focused on lipases containing patatin domains, whereas the roles of other ...
