CrustCheck: a conceptual framework for interpreting biocrust trait–function relationships in drylands

Restoration Ecology, EarlyView.
Abstract Introduction Biocrusts are increasingly recognized for their contribution to soil stability, hydrology, nutrient cycling, and energy balance in drylands, yet practical field methods for assessing functional roles are limited. Existing approaches typically rely on cover estimates, taxonomic identification, or laboratory analyses, providing ...

Spherulite in the modern aragonitic travertine stromatolite has a calcite core with exopolymers

Sedimentology, EarlyView.
ABSTRACT Spherulites are spherical to ellipsoidal particles formed by various crystalline substances and can be abiotically synthesised in the laboratory. Among various spherulite types, spherulites composed of calcium carbonate are also found in various natural environments, but their abiotic or biotic origins are still controversial.

Determination of Intracellular Osmolytes in Cyanobacterial Cells

Bio-Protocol, 2018
Most of the cyanobacteria accumulate osmolytes including sucrose, glucosylglycerol, in their cells in response to salt stress. Here we describe a protocol of our laboratory for extraction and quantification of cyanobacterial intracellular sucrose and ...

The Plasticity of the Antioxidant Defence System of Coastal Zooplankton Communities

Ecology and Evolution, Volume 16, Issue 7, July 2026.
In this photo, a copepodite Acartia spp. is represented with Vorticella epiphytes. This photo was taken with the help of a PlanktoScope, which belongs to the Hellenic Centre for Marine Research. Photographer: Andriana Koutsandrea. ABSTRACT Zooplankton are expected to enhance their antioxidant defences and activate stress‐related biomarkers in response ...

Genetic relation between three morphological states of N2-fixing Cyanobacteria by using PCR technique

مجلة مركز بحوث التقنيات الاحيائية, 2015
Three nitrogen fixing Cyanobacteria purified isolates were selected which express the three morphological states, first Oscillatoria chlorina as an example of filamentous non Heterocysts Cyanobacteria and second Microcystis rubusta as an example of ...

Transmission electron microscopy characterisation of Spirulina bioplastics

Journal of Microscopy, Volume 303, Issue 1, Page 101-119, July 2026.
Abstract Plastic pollution is impacting global ecosystem health. Bioplastics made from unprocessed biomass, including whole or fragmented tissues, are one potential solution. They are biodegradable and exhibit competitive mechanical performance. Seaweed and microalgae have gained popularity over the last decade as bioplastic feedstocks due to their ...

Photosynthesis regulation impacts carbon and nitrogen assimilation in the diazotrophic cyanobacterium Anabaena sp. PCC 7120

New Phytologist, Volume 251, Issue 1, Page 94-110, July 2026.
Model of intercellular functional coordination in Anabaena. Summary Diazotrophic cyanobacteria fix both atmospheric carbon (C) and nitrogen (N) into biomass, but the two assimilation pathways are not compatible. Species like Anabaena sp. PCC 7120 physically separate C and N assimilation in different cell types.

Comparison of Envelope-Related Genes in Unicellular and Filamentous Cyanobacteria

Comparative and Functional Genomics, 2007
To elucidate the evolution of cyanobacterial envelopes and the relation between gene content and environmental adaptation, cell envelope structures and components of unicellular and filamentous cyanobacteria were analyzed in comparative genomics. Hundreds of envelope biogenesis genes were divided into 5 major groups and annotated according to their ...
