Rapid sexual reproduction intensifies blooms of a mixotrophic dinoflagellate

Limnology 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 ...

Diversity and environmental drivers of toxic microalgae in coastal waters of Panama: ecological and public health implications

Frontiers in Marine Science
Harmful algal blooms (HABs) constitute an emerging ecological and public health concern in tropical coastal ecosystems, particularly where high biodiversity intersects with increasing anthropogenic pressures.

Blood Lead Levels in Adults and Children of East Otago Communities, New Zealand: Findings From a Public Health Response to Lead Detected in Drinking Water

Public Health Challenges, Volume 5, Issue 2, June 2026.
Blood lead levels (BLLs) in East Otago adults and children were similar to prior New Zealand estimates, with no consistent evidence of elevation in the exposed population. BLLs were higher than comparable high‐income countries, likely reflecting exposure from known sources. Ongoing public health action is required to reduce lead exposure.

Update of the risk assessment on dioxins and dioxin‐like PCBs in feed and food

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Commission asked EFSA to update its 2018 risk assessment on polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (DL‐PCBs) in feed and food, based on the 2022 WHO Toxic Equivalency Factors (WHO2022‐TEFs).

Paralytic shellfish toxins and associated toxin profiles in bivalve mollusc shellfish from Argentina

, 2020
Paralytic Shellfish Poisoning is a potentially fatal syndrome, resulting from the filter-feeding activities of marine molluscs accumulating harmful neurotoxins naturally occurring in microalgae.

Green Proteins: A Sustainable Alternative to Animal‐Based Proteins for Global Protein Security

Food Frontiers, Volume 7, Issue 3, May 2026.
This study highlights the drawbacks associated with animal‐based proteins, such as their contribution to greenhouse gas emissions, large‐scale land use, and worsening food insecurity. It suggests that green sources of proteins, including legumes, grains, seeds, leaves, and algae, are possible sustainable alternatives. Shifting towards these plant‐based

The analysis of lipophilic marine toxins : development of an alternative method

, 2010
Lipophilic marine toxins are produced by certain algae species and can accumulate in filter feeding shellfish such as mussels, scallops and oysters. Consumption of contaminated shellfish can lead to severe intoxications such as diarrhea, abdominal cramps
