Sedimentary DNA and Fossil Archives Reveal Long‐Term Phytoplankton Shifts and Their Biogeochemical Influence in a Subtropical Lake

Molecular Ecology, Volume 35, Issue 16, August 2026.
ABSTRACT Understanding long‐term phytoplankton community dynamics is essential for assessing ecological resilience and informing lake management under global change. However, centennial‐scale patterns of phytoplankton dynamics remain poorly resolved due to the limited taxonomic resolution of traditional fossil‐based paleoecological approaches.

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 ...

Iron–Phosphorus–Carbon Coupled Cycling in Lacustrine System of Ordos Basin During the Middle Triassic

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Widespread organic‐rich shales are associated with perturbations in productivity or preservation conditions; however, the major controlling factors, especially the phosphorus (P) and iron (Fe) interactions and their impacts on organic carbon burial in the paleolake ecosystem remain poorly understood.

Effects of temporal and spatial variability in energy fluxes on phytoplankton

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Climate change has significantly altered the energy dynamics of lakes; however, little is known of how the temporal and spatial variation in energy fluxes impacts the structure and function of lake ecosystems. This study combined long‐term (2011–2018) measurements of lake energy fluxes with environmental, nutrient, and phytoplankton data at ...

Epilithic Algal and Meiofaunal Assemblages of Arctic/Alpine Lakes and Streams Along Latitudinal and Environmental Gradients in Scandinavia

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Epilithic biofilms along a latitudinal gradient of Arctic/alpine lakes and streams were analysed for their composition of algae (incl. cyanobacteria) and meiofaunal assemblages and correlated these with environmental variables. The composition of algal, meiofauna and nematode assemblages differed between lakes and streams.

Divergent Response of Host‐Specific Driven Gut Microbial Stability in Freshwater Gastropods to Cyanobacterial Blooms

Ecology and Evolution, Volume 15, Issue 11, November 2025.
In this study, two freshwater gastropods (Bellamya aeruginosa and Pomacea canaliculata) were used as controls to study the differences in the effects of cyanobacteria on their gut microbial communities in ponds with the absence of cyanobacterial blooms. Cyanobacterial blooms cause distinct differences in the diversity, community structure, and assembly
