Cretaceous moss–cyanobacteria association reveals trophic interactions in polar forests of Antarctica

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3627-3639, September 2026.
Kimmerera cyanifera gen. et sp. nov. with associated cyanobacteria, holotype UWBM 116051. Summary Through symbiotic associations with microbes, mosses play many important ecological roles in terrestrial ecosystems, such as facilitating trophic interactions and nitrogen cycling.

Dual Cytoplasmic and Chloroplastic Mechanisms Fine‐Tune Chloroplast Division through ARC3 Protein Stability

open access: yesAdvanced Science, Volume 13, Issue 45, 13 August 2026.
ARC3 levels are controlled by cytosolic and chloroplast proteolytic systems. PUB52 mediates ARC3 precursor ubiquitination and degradation in the cytosol, while CLPC1 promotes ARC3 degradation in chloroplasts, where ARC2 protects ARC3 from excessive breakdown. Disrupting these components causes chloroplast division defects, placing them upstream of ARC3.

Response of the Diet Composition of Carassius auratus to Water Quality in Dianchi Lake, China

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Understanding the relationship between the diet composition of fish and water quality is significant for assessing fish responses to habitat changes. However, due to the complexity and diversity of both fish feeding and water quality, the relationship between the diet composition of fish and water quality is not fully understood to date.

Setae thickening in Daphnia magna alleviates the food stress caused by the filamentous cyanobacteria

open access: yesAquatic Ecology, 2017
It is assumed that daphnids adjust the filter screen morphology in order to minimize the interference with cyanobacterial filaments. The aim of this study was to investigate the impact of filamentous cyanobacteria (Aphanizomenon gracile Lemmermann ...

A Review of the Effects of Freshwater Habitat Quality on Aquatic & Semi‐Aquatic Turtles

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
This literature review aims to provide a comprehensive review of the relationship between freshwater turtles and their aquatic environments. We also highlight areas which have been over‐ or under‐studied and offer recommendations for future research. ABSTRACT Freshwater turtles and terrapins require an aquatic habitat as part of their natural ecology ...

A Multilocus Nanopore eDNA Workflow for Red Algal Diversity Assessment in an Algal Reef System

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
This study evaluates an Oxford Nanopore Technologies long‐read sequencing workflow using a multilocus eDNA approach to assess red algal (Rhodophyta) biodiversity in coastal waters. Results demonstrate that while a combination of rbcL, rpoC1, and psbA markers (but not COI‐5P) provides the most comprehensive taxonomic coverage, eDNA signals are heavily ...

Biological soil crusts on patterned grounds and their influence on plant succession [PDF]

open access: yesPolish Polar Research
The taxonomical diversity of cyanobacterial-microalgal crusts (CMC) forming on various types of patterned grounds (PG) and their dependence on some environmental variables were studied.

Hydrogen Sulfide Delivery in Sulfurous Thermal Waters: Saturnia as a Translational Model for Gasotransmitter Pharmacology—A Narrative Review

open access: yesHealth Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background Hydrogen sulfide (H2S) is an endogenous gasotransmitter regulating redox balance, inflammation, and vascular tone, but reproducing the spatial and kinetic features of endogenous production remains challenging. We examine sulfurous thermal waters as natural contexts of sustained H2S exposure, using the Saturnia springs (Tuscany ...

Impact of filamentous cyanobacteria on the water quality of two tropical reservoirs

open access: yes, 2017
Artificial lakes play an important role in water availability in tropical semi-arid Northeastern Brazil. However, in addition to the negative effects that dams have on the water quality of rivers, other practices such as discharge of untreated wastewater,

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 8, Page 1463-1480, August 2026.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman
