Every living thing needs food, also known as nutrients. In nature, living things are connected through food webs. Food webs show us how animals and plants are related through feeding relationships, like birds eating fish. But how do nutrients get returned back into the food web? The answer is bacteria! Bacteria are impossible to see with the naked eye. But, they are found almost everywhere in the world and are very important for recycling nutrients within habitats, like a river. Scientists use…

Dominance of particle-attached bacteria in the Columbia River estuary, USA

The hydrodynamics of the estuary contribute to the dominance of Pdrticle­ attached bacteria by extending the residence time of pdrticles in the ETM, and by quickly flushing free­ living cells through the estudry, perhaps preventing the development of an estudrine population of free-living bacterid.

Viral abundance in aquatic systems:a comparison between marine and fresh waters

The virusto-bacteria ratio was significantly higher in freshwater than marine environments, and there were significantly more bacteria per unit chlorophyll in the authors' freshwater samples, suggesting that this difference is related to the increased dependence of freshwater bacteria on allochthonous material relative to marine systems, as well as the increased relative importance of photosynthetic cyanobacteria in lakes.

Metagenomic insights into particles and their associated microbiota in a coastal margin ecosystem

The discussion on the use of high-throughput sequence data to relate microbial community structure and function to the origin, fate and transport of particulate organic matter (POM) in coastal margins is expanded.

Contrasting genomic properties of free-living and particle-attached microbial assemblages within a coastal ecosystem

A metagenome perspective on ecosystem-scale metabolism in an upwelling-influenced river-dominated coastal margin is provided, indicating possible formation of anoxic microniches within particles.

Determining indicator taxa across spatial and seasonal gradients in the Columbia River coastal margin

It was found that in the Columbia River coastal margin, freshwater-influenced environments were consistent and predictable, whereas coastal ocean community variability was difficult to interpret due to complex physical conditions.

IMG/M is a data management and analysis system for microbial community genomes (metagenomes) hosted at the Department of Energy's (DOE) Joint Genome Institute (JGI). IMG/M consists of metagenome data
