Phytoplankton Morpho-Functional Trait Variability along Coastal Environmental Gradients
Microorganisms, 2021 We utilized the trait-based approach in a novel way to examine how specific phytoplankton traits are related to physical features connected to global change, water quality features connected to catchment change, and nutrient availability connected to ...

Global genetic capacity for mixotrophy in marine picocyanobacteria [PDF]
The ISME Journal, 2016 Abstract The assimilation of organic nutrients by autotrophs, a form of mixotrophy, has been demonstrated in the globally abundant marine picocyanobacterial genera Prochlorococcus and Synechococcus. However, the range of compounds used and the distribution of organic compound uptake genes within picocyanobacteria are unknown.

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 ...

Mixotrophy drives niche expansion of verrucomicrobial methanotrophs [PDF]
The ISME Journal, 2017 Abstract Aerobic methanotrophic bacteria have evolved a specialist lifestyle dependent on consumption of methane and other short-chain carbon compounds. However, their apparent substrate specialism runs contrary to the high relative abundance of these microorganisms in dynamic environments, where the availability of methane and oxygen ...

An updated view on the long‐term survival and significance of marine protist resting stages
Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.Abstract Resting stages of protists act as biological time capsules when buried in marine sediments, preserving viable cells that enable the study of ecological and evolutionary processes across timescales. Recent studies have extended the known viability in diatoms to several millennia and in dinoflagellates to over a century, while also identifying ...

CLEAN – Soil, Air, Water, Volume 54, Issue 6, June 2026.ABSTRACT Dairy wastewater has raised many concerns because it is highly contaminated with high levels of organic matter. The major sources of contaminants in dairy wastewater are clean‐in‐place products, which are used to sanitize production lines, and whey, which is a byproduct of cheese and pressed yogurt.

Quagmires around southern and southeastern Estonian lakes [PDF]
Mires and Peat, 2019 We studied quagmires around 17 soft-water lakes in southern and southeastern Estonia. Vegetation analysis was carried out at the level of moss and field layer synusiae and plant communities.

Topic Modeling of Fatty Acid Studies: Evaluating Environmental Changes in Freshwater Ecosystems
International Review of Hydrobiology, Volume 111, Issue 1, June 2026.ABSTRACT Fatty acids (FAs) are biochemical molecules with vital structural and metabolic functions in all living organisms. Over the last decades, FA analysis in ecological studies has garnered significant attention due to its diverse applicability, such as taxonomic support for species identification, investigations on trophic interactions, and ...

Urea provides an important nitrogen source for microbial populations in an ultraoligotrophic sea
Limnology and Oceanography, Volume 71, Issue 6, June 2026.Urea is an organic nitrogen (N) compound directly utilized by both heterotrophic prokaryotes and some photoautotrophs. Reports of either ambient urea concentrations or urea uptake rates from the ultraoligotrophic eastern Mediterranean Sea are lacking. We investigated urea distribution and uptake in the upper water column in the Levantine basin during ...
