Stabilizing microbial communities by looped mass transfer [PDF]

open access: yesProceedings of the National Academy of Sciences, 2021
Significance The population ecology of microbial communities is still poorly understood and their notorious instability makes them impossible to control. Much of the instability is caused by the stochastic assembly of microorganisms, especially in highly diverse microbiomes where structural and hence functional changes occur rapidly ...

How Do Quorum-Sensing Signals Mediate Algae–Bacteria Interactions?

open access: yesMicroorganisms, 2021
Quorum sensing (QS) describes a process by which bacteria can sense the local cell density of their own species, thus enabling them to coordinate gene expression and physiological processes on a community-wide scale.

The production of dissolved organic carbon by macroalgae and its consumption by marine bacteria: Implications for coastal ecosystems

open access: yesFrontiers in Marine Science, 2022
Through the fixation of large quantities of dissolved inorganic carbon (DIC), macroalgae facilitate the energetic foundation of highly productive coastal ecosystems.

Bottom-Up Control of the Groundwater Microbial Food-Web in an Alpine Aquifer

open access: yesFrontiers in Ecology and Evolution, 2022
Groundwater ecosystems are typically poor in organic carbon and productivity sustaining a low standing stock of microbial biomass. In consequence, microbial food webs in oligotrophic groundwater are hypothesized to be bottom-up controlled.

Phosphorus Release and Regeneration Following Laboratory Lysis of Bacterial Cells

open access: yesFrontiers in Microbiology, 2021
The availability of phosphorus limits primary production in large regions of the oceans, and marine microbes use a variety of strategies to overcome this limitation.

Microbial Grazers May Aid in Controlling Infections Caused by the Aquatic Zoosporic Fungus Batrachochytrium dendrobatidis

open access: yesFrontiers in Microbiology, 2021
Free-living eukaryotic microbes may reduce animal diseases. We evaluated the dynamics by which micrograzers (primarily protozoa) apply top-down control on the chytrid Batrachochytrium dendrobatidis (Bd) a devastating, panzootic pathogen of amphibians ...

Differences in Bacterial Growth and Mortality between Seagrass Meadows and Adjacent Unvegetated Areas

open access: yesJournal of Marine Science and Engineering, 2023
A seagrass meadow is one of the most important ecosystems around the world, both economically and ecologically. An important feature of this ecosystem is the presence of large coastal seagrass beds, which dominate the primary production and contribute to

Microbial loop of a Proterozoic ocean analogue [PDF]

open access: yes, 2021
Abstract Meromictic Lake Cadagno, an ancient ocean analogue, is known for its permanent stratification and persistent anoxygenic microbial bloom within the chemocline. Although the anaerobic microbial ecology of the lake has been extensively studied for at least 25 years, a comprehensive picture of the microbial food ...

Parameterizing the microbial loop: an experiment in reducing model complexity [PDF]

open access: yes, 2004
The structure of the plankton food web in the upper mixed layer has important implications for the export of biogenic material from the euphotic zone. While the action of the microbial loop causes material to be recycled near the surface, activity of the

Bacterial Metabolic Response to Change in Phytoplankton Communities and Resultant Effects on Carbon Cycles in the Amundsen Sea Polynya, Antarctica

open access: yesFrontiers in Marine Science, 2022
We investigated changes in heterotrophic bacterial metabolic activities and associated carbon cycles in response to a change in dominant phytoplankton communities during two contrasting environmental conditions in austral summer in the Amundsen Sea ...
