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 ...

Mass Spectral Characterisation of Three New Groups of Algal Toxins [PDF]

open access: yes, 2009
This thesis reports the mass spectral identification and characterisation of three new groups of algal compounds. A series of novel pectenotoxins (PTXs) were identified in retained sub-samples of Irish mussel extracts that had previously been utilised ...

Rapid sexual reproduction intensifies blooms of a mixotrophic dinoflagellate

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Sexual reproduction is fundamental to the ecology and evolution of eukaryotes, yet its dynamics in microbial eukaryotes are often cryptic. Dinophysis are specialist mixotrophs that must balance prey capture, cell division, and sexual recombination during blooms, but relatively little is known about the occurrence and role of sex in their ...

Reversible Regime Change: Climate‐Driven Phytoplankton Community Shifts in the Cariaco Basin, Venezuela

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Phytoplankton communities are integral to oceanic biogeochemical cycles and are sensitive indicators of climate‐driven environmental variability. Long‐term time series capture this variability, allowing us to unravel the effects of environmental change on local communities.

An assessment of Dinophysis blooms in the coastal Arabian Sea

open access: yes, 2014
Dinoflagellate blooms of the genus Dinophysis occur regularly in the coastal Arabian Sea. By producing toxins, which may accumulate in marine bivalves, they impose threat to human health. Using time-series data on environmental variables (e.g., nutrients,
