Changing Pacific Salmon Nursery Lake Ecosystem Dynamics Over Centuries to Millennia: Insights From Sedimentary DNA Metabarcoding

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Sedimentary DNA metabarcoding tracks long‐term eukaryotic community change in Pacific salmon nursery lakes, revealing potential land‐use and climate influences on algal communities and resilience indicators. ABSTRACT Pacific salmon are keystone species in North Pacific freshwater, riparian, and marine ecosystems, but many populations have declined or ...

Phytoplankton growth and potential cyanotoxin production differ in response to nitrogen and phosphorus amendments in late summer communities from Kabetogama Lake (Minnesota, United States)

Journal of Phycology, Volume 62, Issue 3, Page 883-903, June 2026.
Abstract Cyanotoxins such as microcystin (MC), cylindrospermopsin, and saxitoxin are secondary metabolites that are rich in nitrogen (N). Most cyanobacteria grow best on reduced inorganic N (ammonium, NH4), but when NH4 is absent, cyanobacteria can activate physiological pathways to process other N forms (e.g., nitrate; NO3).

Comparison between fluorometry and microscopy‐based phytoplankton assessments in the Laurentian Great Lakes

Limnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract Photosynthetic pigment fluorescence is commonly used in limnology and oceanography as a proxy for phytoplankton biomass. Fluorometry has been used to detect subsurface algal blooms, characterize dynamics of the deep chlorophyll layer, and to provide greater vertical resolution to phytoplankton monitoring.

The Morphology and Small Subunit rDNA Gene Phylogeny of the Novel Goniomonad Genus Ebisugoniomonas and Two Novel Poseidogoniomonas Species

Journal of Eukaryotic Microbiology, Volume 73, Issue 3, May/June 2026.
ABSTRACT Goniomonads are representatives of Cryptista. They are morphologically and genetically diverse, comprising nine genera described so far. 18S rDNA data has revealed at least one more monophyletic genus‐level lineage, as well as novel species within currently described genera. The molecular diversity of goniomonads is not fully investigated, and

Seasonal Environmental Conditions and River Morphology Shape Summer Phytoplankton Communities

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Phytoplankton form the base of large river food webs, but there are limited studies on the nature and drivers of communities over longer time scales. Further, climate change is projected to favour taxa associated with harmful algal blooms, but our knowledge of the timing, locations and drivers of cyanobacteria in rivers lags that of lakes and ...
