Toxic dinoflagellates (dinophysis spp.) detection by genosensors and molecular biology approaches

open access: yes, 2023
Over the years, the marine ecosystems integrity has been compromised, due to multiple factors that disrupt the natural balance of phytoplankton. Factors such as the unregulated runoff of agricultural and industrial wastes into the aquatic environment and higher surface temperatures are believed to have transformed these ecosystems into favorable ...

Multi‐Tool Marine Metabarcoding Bioassessment for Baselining and Monitoring Species and Communities in Kelp Habitats

open access: yesMolecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT The astonishing biological diversity found in Californian kelp forests requires efficient and robust monitoring tools to better understand ecological trends and mitigate against loss or disruption of ecosystem services due to human pressure and climate changes.

Expanding Monitoring Capacity for Potential Invasive Species in Arctic Canada With Environmental DNA Metabarcoding

open access: yesGlobal Change Biology, Volume 31, Issue 9, September 2025.
Rapidly changing climatic conditions combined with increasing shipping traffic is going to accelerate the introduction and persistence of marine invasive species in Arctic Canada. To address this emerging threat, we propose seawater environmental DNA metabarcoding on board ships of opportunity (i.e., cruise ships) as a cost‐effective method for ...

Identification of 19-epi-okadaic Acid, a New Diarrhetic Shellfish Poisoning Toxin, by Liquid Chromatography with Mass Spectrometry Detection

open access: yesMarine Drugs, 2008
Okadaic acid (1) (OA) and its congeners are mainly responsible for diarrhetic shellfish poisoning (DSP) syndrome. The presence of several OA derivatives have already been confirmed in Prorocentrum and Dinophysis spp.

Characterization of Dinophysis spp. (Dinophyceae, Dinophysiales) from the mid‐Atlantic region of the United States1

open access: yesJournal of Phycology, 2020
Due to the increasing prevalence of Dinophysis spp. and their toxins on every US coast in recent years, the need to identify and monitor for problematic Dinophysis populations has become apparent. Here, we present morphological analyses, using light and scanning electron microscopy, and rDNA sequence analysis, using a ~2‐kb sequence of ribosomal ITS1 ...

How Does Climate Change Influence the Regional Ecological–Social Risks of Harmful Dinoflagellates? A Predictive Study of China's Coastal Waters

open access: yesGlobal Change Biology, Volume 31, Issue 7, July 2025.
Climate change is expected to shift the risks posed by harmful dinoflagellates in China's coastal waters. In this study, the ecological–social risk is assessed by considering both the potential presence of these algae and their overlap with coastal populations and mariculture areas.

Harmful Algae Records in Venice Lagoon and in Po River Delta (Northern Adriatic Sea, Italy)

open access: yesThe Scientific World Journal, 2014
A detailed review of harmful algal blooms (HAB) in northern Adriatic Sea lagoons (Po River Delta and Venice lagoon) is presented to provide “updated reference conditions” for future research and monitoring activities. In the study areas, the high mollusc

Environmental DNA Documents Ecosystem‐Wide Biodiversity Within the Marine Protected Area Stellwagen Bank National Marine Sanctuary

open access: yesEnvironmental DNA, Volume 7, Issue 3, May–June 2025.
Three marker genes targeting prokaryotic, eukaryotic, and vertebrate diversity were used to assess biodiversity within Stellwagen Bank National Marine Sanctuary. High levels of biodiversity were seen across the sampled area, with distinct communities across surface water, bottom water, and sediment.

Multiple global change factors and the long‐term dynamics of harmful algal blooms in the North Sea

open access: yesLimnology and Oceanography, Volume 70, Issue 5, Page 1267-1282, May 2025.
Abstract The North Sea has been identified as an area where the impacts of climate change and de‐eutrophication efforts are already apparent, specifically on phytoplankton communities, with shifts in biogeography, altered species composition, and increased biomass of harmful algal bloom (HAB) species.
