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

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.

Nutrient disturbance in a shallow aquaculture pond impacts Microcystis gene expression but does not impact bacterial community function during bloom conditions

Journal of Phycology, EarlyView.
Abstract Cyanobacterial harmful algal blooms (cHABs) are worldwide issues. Reduced nitrogen forms (ammonium and urea) have recently been measured in freshwater systems at concentrations not previously recorded. These reduced nitrogen forms have been shown to favor the proliferation of harmful cyanobacteria.

Revisiting the life cycle of Margalefidinium polykrikoides Group III

Journal of Phycology, EarlyView.
Abstract Dinoflagellates produce cysts as a strategy to withstand environmental stressors, with nutrient depletion generally considered a key trigger for cyst production. Resting cysts are thick‐walled, typically composed of one to several layers, and characterized by a prolonged dormancy period.

The consequences of partial clonality on the spatiotemporal genetic structure of the red alga Chondria tumulosa (Ceramiales, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract The relative rates of sexual versus clonal reproduction partition genetic diversity, but the quantification of these rates remains limited in natural populations. This knowledge gap is particularly acute among tropical macroalgae. Chondria tumulosa is a red macroalga that has been documented at high abundance in the three northernmost atolls ...

Optimizing a long‐term monitoring strategy to track emerging cyanobacterial blooms in a Great Lakes estuary

Journal of Phycology, EarlyView.
Abstract Cyanobacterial harmful algal blooms (cHABs) are increasingly frequent and severe globally. Recently, the St. Louis River Estuary (SLRE) has experienced numerous cHABs, but the locations, timing, and environmental conditions associated with them are unknown.

Evaluation of Rayleigh-Corrected Reflectance on Remote Detection of Algal Blooms in Optically Complex Coasts of East China Sea

Remote Sensing
This study used GOCI-II data to systematically evaluate the feasibility of Rayleigh-corrected reflectance (Rrc) to detect algal blooms in the complex optical environment of the East China Sea (ECS).

Cell‐based crop phenotyping for future climates

New Phytologist, EarlyView.
Flow‐chart diagram illustrating the proposed pathway for improving the throughput of fluorescence imaging‐based phenotyping by using robotics and machine learning (ML) approaches. Summary Abiotic stress tolerance has been significantly weakened in modern crops during the domestication process.

An explainable ensemble machine-learning framework for short-term forecasting of algal blooms across contrasting Lake systems

Ecological Informatics
Algal blooms increasingly threaten freshwater ecosystems under escalating anthropogenic pressures and climate warming, yet short-term forecasting remains challenging due to their complex, nonlinear, and region-specific dynamics.
