Combining the Underwater Vision Profiler 6 with sediment traps to measure in situ velocity of marine particles

Limnology and Oceanography: Methods, Volume 24, Issue 7, July 2026.
Abstract Particles sinking from the surface to the deep ocean play a key role in the biological carbon pump, whose efficiency depends partly on sinking velocities. Over the last decade, in situ imaging has enabled critical advances in our understanding of particle dynamics in the ocean.

Global Distribution and Future Projections of Functional Groups Within Extremotolerant Soil Fungi

Global Change Biology, Volume 32, Issue 7, July 2026.
Ecological lifestyles determine the global distribution and future redistribution of extremotolerant soil fungi. ABSTRACT Black fungi are often described as ubiquitous specialists of harsh environments (extremotolerant), yet how their ecological lifestyles vary across environmental gradients remains poorly understood. Here, we use a global soil dataset

Arbuscular mycorrhizal fungal (AMF) communities in sand bars associated with Ipomoea pes‐caprae: a promising strategy for petroleum spill bioremediation in coastal dunes

Restoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction Polycyclic aromatic hydrocarbons (PAHs), a class of petroleum‐derived compounds known for causing cellular damage and for their recalcitrant behavior, severely limit effective biodegradation. Arbuscular mycorrhizal fungi (AMF) from oil‐contaminated environments can mitigate PAH‐related stress on host plants, highlighting the ...

DANIAN (SBZ2) LARGER FORAMINIFERA FROM THE BECIRMAN FORMATION (SOUTHEASTERN TURKEY) AS EVIDENCE OF ROTALIIDS DIVERSITY IN LOWER PALEOCENE SHALLOW-WATER ENVIRONMENTS

Rivista Italiana di Paleontologia e Stratigrafia, 2022
An important shallow marine deposit is described and illustrated with focus on the systematics and biostratigraphy of larger foraminifera from three stratigraphic sections of the Becirman Formation from the Batman and Siirt regions (Southeastern Turkey).

Unifying Retaria Research: A Common Framework for Studying Foraminifera and Radiolaria

BioEssays, Volume 48, Issue 6, June 2026.
Research on Foraminifera and Radiolaria has predominantly focused on their fossil remains. This synthesis identifies the “Big Five” disciplines of a unified Retaria research: diversity and evolution, ecology, life cycles, and ecosystem roles, highlighting this lineage as a model system for understanding life's resilience in a rapidly changing planet ...

RESULTS OF THE STUDY OF LAKE ONEGO ECOSYSTEM IN THE PERIOD OF SUMMER STRATIFICATION BASED ON MEASURED DATA FROM A 2017 EXPEDITION

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018
New data characterizing the hydrophysical features (water temperature), water quality (water transparency, dissolved oxygen, and number of saprophytic bacteria), trophic status (chlorophyll a), and impact of the catchment (water color) of Lake Onego ...

In-depth characterization of diazotroph activity across the western tropical South Pacific hotspot of N₂ fixation (OUTPACE cruise) [PDF]

Biogeosciences, 2018
Here we report N2 fixation rates from a  ∼  4000 km transect in the western and central tropical South Pacific, a particularly undersampled region in the world ocean.

Benthic contributions to the chemical seascape: Insights from Mediterranean underwater caves

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Chemical mediation plays a major role in the functioning of marine ecosystems, yet most of the molecules sustaining species interactions remain largely unknown. As an initial step toward clarifying these processes, this study investigates how benthic biodiversity shapes the chemical composition of seawater, using underwater caves as model ...

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 ...
