Description
Łukasz Wejnerowski and co-authors test whether toxin-making water bacteria actually kill the animals that graze them. Their 2026 study screens strains of cyanobacteria from European and Arctic fresh waters. Many strains can brew a wide menu of poisons, from microcystins to saxitoxins.
Extracts were fed to two Daphnia species, tiny water fleas. Despite loaded chemistry and heavy growth, most extracts barely dented survival. The killers were strains that tested clean on the standard panel, hinting at unknown toxins. More starting biomass oddly went with better survival. The authors raise a growth-versus-toxicity trade-off. Maps of toxic strains gain new entries.
