Hierarchical modeling of Baltic Sea phytoplankton reveals increasing cyanobacteria dominance

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Understanding how phytoplankton communities respond to environmental changes is critical for mitigating the impact of changing oceans. To identify the main drivers of changes in phytoplankton community composition and species richness, hierarchical modeling of species communities (HMSC) was used to model the summer phytoplankton communities ...

Heterotrophic diazotrophy along a river–lake continuum: Lifestyle and contribution to dinitrogen fixation

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Heterotrophic diazotrophs are potentially important to the nitrogen cycle in freshwater ecosystems, yet their abundance, N2 fixation rates, diversity, and association with aggregates remain poorly understood. This study elucidates the contribution of freshwater heterotrophic diazotrophs as free‐living or aggregate‐associated cells to total N2 ...

Microbial‐mediated recycling constrains the contribution of primary production to export flux in an oligotrophic system

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract This study presents the first multi‐year assessment quantifying the contribution of primary production to vertical carbon flux in the ultra‐oligotrophic southeastern Levantine basin of the Mediterranean Sea. Depth‐integrated (0–180 m) daily primary productivity (PP) was 25% higher in the mixed winter period than in the stratified period (123 ...

Heatwaves and a history of variability shape phytoplankton community thermal responses within one generation

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Predicting the effect of increased thermal unpredictability, for example in the shape of heatwaves on phytoplankton metabolic responses is ripe with challenges. While single genotypes in laboratory environments will respond to environmental fluctuations in predictable and repeatable ways, it is difficult to relate rapid evolutionary responses ...

Early Warning System for Toxic Cyanobacteria Blooms

Harmful cyanobacterial blooms produce cyanotoxins which can adversely affect humans and animals. Without proper monitoring and detection programs, tragedies such as the loss of pets or worse are possible. Multiple factors including rising temperatures and human influence contribute to the increased likelihood of harmful cyanobacteria blooms.

Essential dietary fatty acids affect intraspecific competition in herbivorous zooplankton

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract The trophic transfer efficiency at the pelagic phytoplankton‐zooplankton interface is—among other factors—governed by the dietary availability of polyunsaturated fatty acids (PUFAs) to herbivorous zooplankton. As most zooplankton taxa cannot synthesize PUFAs de novo, the phytoplankton PUFA composition is crucial for the herbivores' fitness. As

Phosphorus limitation drives seasonal enlargement of the coccosphere size in two coccolithophores

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Coccolithophores are abundant marine microalgae that produce a cell cover (coccosphere) composed of calcium carbonate platelets (coccoliths), and that play a unique role in the global carbon cycle. Gephyrocapsa huxleyi is the most prevalent coccolithophore in the oceans. Experiments in vitro indicate that the coccosphere size in G.

Microbial diversity, genomics, and phage–host interactions of cyanobacterial harmful algal blooms

mSystems
The occurrence of cyanobacterial harmful algal blooms (cyanoHABs) is related to their physical and chemical environment. However, less is known about their associated microbial interactions and processes.

Extreme summer storm elicits shifts in biogeochemistry, primary productivity, and plankton community structure in a large‐scale lake enclosure experiment

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Climate change increases the magnitude and frequency of extreme weather events. This includes severe summer storms altering lake physical structure, biodiversity and ecosystem processes. However, insights into lake responses to extreme storms and the underlying mechanisms primarily rest on unreplicated and observational case studies, without ...
