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

open access: yesJournal 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.

The State of Knowledge of Harmful Algal Blooms of Margalefidinium polykrikoides (a.k.a. Cochlodinium polykrikoides) in Latin America

open access: yesFrontiers in Marine Science, 2019
The marine dinoflagellate Margalefidinium polykrikoides is a harmful species that has affected aquaculture, fisheries and tourism activities. It produces reactive oxygen species (ROS) as well as hemolytic and neurotoxic-like substances that have been ...

Revisiting the life cycle of Margalefidinium polykrikoides Group III

open access: yesJournal 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.

Harmful algal blooms: causes, impacts and detection

open access: yesJournal of Industrial Microbiology and Biotechnology, 2003
Blooms of autotrophic algae and some heterotrophic protists are increasingly frequent in coastal waters around the world and are collectively grouped as harmful algal blooms (HABs). Blooms of these organisms are attributed to two primary factors: natural processes such as circulation, upwelling relaxation, and river flow; and, anthropogenic loadings ...

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

open access: yesJournal 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.

Kelp‐boulder transplants for habitat restoration

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Degraded habitats present a major barrier to the survival and recovery of threatened marine species, particularly where structural or biogenic complexity has been lost, and natural regeneration ability is uncertain. Despite growing interest in habitat restoration, techniques rarely deliver rapid improvements at the necessary ...

Warming and freshening coastal waters impact harmful algal bloom frequency in high latitudes

open access: yesCommunications Earth & Environment
Harmful algal blooms contaminate seafood with toxins and poison humans and wildlife upon consumption. Toxic algae niches are projected to expand in high latitudes, but how the frequency of their blooms will evolve is still little known.

Marine Biotoxins and Seafood Poisoning

open access: yesToxins, 2019
Prevalence of marine biotoxins in seafood has been associated with increasing frequency, intensity, and duration of harmful algal blooms, and an increase of the geographical and temporal distribution of harmful algae [...]

The Benefits of High Resolution Multispectral TIR Data and Its Impending Loss by NASA After Four Decades

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract NASA has led multispectral (≥3 wavelength bands) thermal infrared (TIR) sensor development from the earliest days of the agency. These data are critical in addressing a wide range of scientific questions and administration priories by measuring both temperature (for wildfire and volcanic eruption monitoring, agricultural plant stress, and ...

The Zooplankton International Geospatial dataset: A global repository of spatiotemporal freshwater zooplankton community composition data from lakes and reservoirs to support ecological research

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Zooplankton transfer substantial energy in aquatic food webs and are used as indicators of environmental change. Syntheses of zooplankton community dynamics globally require datasets that span a wide range of environmental gradients; however, these datasets are limited due to methodological differences across programs, taxonomic ...
