Marine Biotoxins: Occurrence, Toxicity, Regulatory Limits and Reference Methods

open access: yesFrontiers in Microbiology, 2016
Harmful algal blooms are natural phenomena caused by the massive growth of phytoplankton that may contain highly toxic chemicals, the so-called marine biotoxins causing illness and even death to both aquatic organisms and humans.

Commercially Exploited Seaweed Species in Africa: Occurrences, Chemical Composition, Current Value Chain and Opportunities for Value Addition

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
Commercially exploited seaweed species in Africa, their biochemical composition, current uses, and value chain are reviewed. Potential value‐addition of seaweed is suggested regionally in Africa amongst countries producing similar seaweed species. ABSTRACT Africa has a wide range of coastal environments that support a diverse array of seaweed species ...

Fear of grazing rivals the toxin‐inducing effects of nutrients in two marine harmful algae – a meta‐analysis

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1904-1921, August 2026.
ABSTRACT One of the major subfields of chemical ecology is the study of toxins and how they mediate interactions between organisms. Toxins produced by harmful algae (phycotoxins) impact a wide variety of organisms connected to the marine food web. Significant research efforts have thus aimed to identify the ecological and evolutionary drivers behind ...

Shellfish Toxins Targeting Voltage-Gated Sodium Channels

open access: yesMarine Drugs, 2013
Voltage-gated sodium channels (VGSCs) play a central role in the generation and propagation of action potentials in excitable neurons and other cells and are targeted by commonly used local anesthetics, antiarrhythmics, and anticonvulsants. They are also

Using Machine Learning to Predict Phytoplankton Blooms in the Salish Sea

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Strong phytoplankton blooms occur every spring in the Salish Sea, but vary significantly, spatially and temporally. Natural variability and climate change make the prediction of the bloom challenging, as they affect both atmospheric drivers and nutrient interactions that contribute to the growth of phytoplankton. Understanding these drivers is

Social information about others' affective states in a human‐altered world

open access: yesJournal of Animal Ecology, Volume 95, Issue 8, Page 1311-1325, August 2026.
Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...
