Sponges are celebrated heterotrophs but also key primary producers on changing coral reefs

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Trophic interactions and nutrient cycling lay at the heart of ecosystem health and biodiversity. In recent years, our understanding of these drivers has been repeatedly challenged by rapid and unanticipated climatic effects, combined with an increasing awareness that ...

tRNA functional signatures classify plastids as late-branching cyanobacteria. [PDF]

, 2019
BackgroundEukaryotes acquired the trait of oxygenic photosynthesis through endosymbiosis of the cyanobacterial progenitor of plastid organelles. Despite recent advances in the phylogenomics of Cyanobacteria, the phylogenetic root of plastids remains ...

Assessing the Toxicity of Leachates From Weathered Plastics on Photosynthetic Marine Bacteria Prochlorococcus

Frontiers in Marine Science, 2020
Marine plastic pollution is a well-recognized, global problem. Research addressing plastic pollution has largely focused on investigating impacts on macroorganisms, with few studies investigating effects on marine microbes.

Photosynthetic primary production in the Mesoproterozoic

New Phytologist, EarlyView.
Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.

Knowledge Rich Natural Language Queries over Structured Biological Databases

, 2017
Increasingly, keyword, natural language and NoSQL queries are being used for information retrieval from traditional as well as non-traditional databases such as web, document, image, GIS, legal, and health databases. While their popularity are undeniable

Microcosm experiments reveal source‐specific impacts of atmospheric aerosols on plankton communities and organic matter in the sea surface microlayer

Limnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract The impact of atmospheric deposition on marine ecosystems requires consideration of the interfacial processes within the sea surface microlayer, the uppermost layer at the air–sea interface. This study examines the impact of anthropogenic and biomass burning aerosol particles on the plankton community structure and organic matter accumulation ...

Thiol post‐translational modifications modulate allosteric regulation of the OpcA–G6PDH complex through conformational gate control

Protein Science, Volume 35, Issue 5, May 2026.
Abstract In cyanobacteria, the redox‐sensitive protein OpcA acts as a metabolic switch for G6PDH, enabling rapid adjustment of reducing power generation from glycogen catabolism and thereby precisely regulating carbon flux between anabolic and catabolic pathways.

A Model of Genome Size Evolution for Prokaryotes in Stable and Fluctuating Environments [PDF]

, 2015
Temporal variability in ecosystems significantly impacts species diversity and ecosystem productivity and therefore the evolution of organisms. Different levels of environmental perturbations such as seasonal fluctuations, natural disasters, and global ...

Mechanisms of silver nanoparticle toxicity on the marine cyanobacterium Prochlorococcus under environmentally-relevant conditions.

Science of the Total Environment, 2020
Global demand for silver nanoparticles (AgNPs), and their inevitable release into the environment, is rapidly increasing. AgNPs display antimicrobial properties and have previously been recorded to exert adverse effects upon marine phytoplankton. However,

Disentangling top-down drivers of mortality underlying diel population dynamics of Prochlorococcus in the North Pacific Subtropical Gyre

bioRxiv, 2021
Photosynthesis fuels primary production at the base of marine food webs. Yet, in many surface ocean ecosystems, diel-driven primary production is tightly coupled to daily loss.
