University of Nevada, Reno researchers: anatoxin timing differs by species; oxygen/metabolism sensors may aid forecasting
Summary
Researchers presented preliminary results showing different benthic cyanobacteria taxa (Anabaena/Cylindrospermum vs Microcoleus) peak at different times; dissolved‑oxygen based metabolism models may help predict when anatoxin concentrations will rise, and early evidence suggests benthic mats alter invertebrate communities.
Joanna Blaschuck, a researcher at the University of Nevada, Reno, presented preliminary findings from a multi‑year study of benthic anatoxin‑producing cyanobacteria in Northern California rivers.
Blaschuck said the team monitored reaches on the South Fork Eel and other rivers weekly in 2023 and 2024 and combined benthic transect surveys, mat composites, toxin analyses (LC‑MS/MS), microscopy and dissolved‑oxygen sensors used to…
