Aggregation of mineral particles in cryoconite granules by multiple species of cyanobacteria on Urumqi Glacier No.1, China

Frontiers in Earth Science
Cryoconite granules are microbial aggregations formed by filamentous cyanobacteria with mineral particles on the bare ice surface of glaciers worldwide.

Polyadenylated RNA in two filamentous cyanobacteria. [PDF]

Journal of Bacteriology, 1983
Polyadenylated RNA was detected in the cyanobacteria Nostoc sp. strain MAC and Anabaena variabilis by oligodeoxythymidylic acid-cellulose chromatography and by hybridization to [3H]polyuridylic acid. Polyadenylate tracts from A. variabilis were located at the 3' end of RNA chains and had an estimated length of 15 to 22 nucleotides.

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures

Advanced Robotics Research, EarlyView.
This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

Exploring Bioactive Properties of Marine Cyanobacteria Isolated from the Portuguese Coast: High Potential as a Source of Anticancer Compounds

Marine Drugs, 2013
The oceans remain a major source of natural compounds with potential in pharmacology. In particular, during the last few decades, marine cyanobacteria have been in focus as producers of interesting bioactive compounds, especially for the treatment of ...

Bioflocculation and settling studies of native wastewater filamentous cyanobacteria using different cultivation systems for a low-cost and easy to control harvesting process.

Journal of Environmental Management, 2019
Bioflocculation phenomena for filamentous cyanobacteria were studied and analysed in two different cultivation systems (i.e. based on air-bubbling and on shaking) and for different initial biomass concentrations.

Synergistic Regulation of Soil Function and Wind Erosion Resistance by Sand Barriers, Vegetation, and Artificial Biological Crust in the Tengger Desert

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian desertification poses a critical threat to ecosystem stability in arid regions worldwide. Although the combination of sand barriers and vegetation has been widely applied for sand fixation, its long‐term effectiveness is constrained by barrier degradation, slow natural development of biological soil crusts (BSCs), and the resulting ...

Artificial intelligence to explain the variables that favor the cyanobacteria steady-state in tropical ecosystems: A Bayeasian network approach

Anais da Academia Brasileira de Ciências, 2023
The steady-state is a situation of little variability of species dominance and total biomass over time. Maintenance of cyanobacteria are often observed in tropical and eutrophic ecosystems and can cause imbalances in aquatic ecosystem. Bayeasian networks

A simplified two‐station approach for modeling metabolism in dam tailwaters subject to diel flow variation

Limnology and Oceanography: Methods, EarlyView.
Abstract Tailwaters are ubiquitous and highly managed ecosystems whose food webs often rely disproportionately on autochthonous energy. In situ continuous dissolved oxygen data are increasingly being used to estimate gross primary productivity and ecosystem respiration in rivers, but this approach is complicated in tailwaters, where upriver ...

Photophobotaxis of single celled and filamentous cyanobacteria

Photochemistry and Photobiology
Phototaxis refers to an organism’s movement toward a light source, while photophobotaxis involves movement into illuminated regions. Although phototaxis in cyanobacteria has been widely studied, photophobotaxis has been investigated in only a few species.

Integrating and assessing metacommunity drivers of ecosystem function and resilience in benthic algal systems

Oikos, EarlyView.
Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...
