[HTML][HTML] Origin, dynamics, and implications of extracellular DNA pools in marine sediments
In marine sediments, DNA occurs both inside and outside living organisms. DNA not
enclosed in living cells may account for the largest fraction of total DNA, and include …

Significance of predation by protists in aquatic microbial food webs
EB Sherr, BF Sherr - Antonie Van Leeuwenhoek, 2002 - Springer
Predation in aquatic microbial food webs is dominated by phagotrophic protists, yet these
microorganisms are still understudied compared to bacteria and phytoplankton. In pelagic …

Predation on prokaryotes in the water column and its ecological implications
J Pernthaler - Nature Reviews Microbiology, 2005 - nature.com
The oxic realms of freshwater and marine environments are zones of high prokaryotic
mortality. Lysis by viruses and predation by ciliated and flagellated protists result in the …

Plankton and nutrient dynamics in marine waters
L Legendre, F Rassoulzadegan - Ophelia, 1995 - Taylor & Francis
Biological oceanographers generally distinguish between two contrasting trophic pathways
in the pelagic environment, ie the herbivorous and the microbial food webs. The former goes …

The uptake of inorganic nutrients by heterotrophic bacteria
DL Kirchman - Microbial Ecology, 1994 - Springer
It is now well known that heterotrophic bacteria account for a large portion of total uptake of
both phosphate (60% median) and ammonium (30% median) in freshwaters and marine …

Metabolic and trophic interactions modulate methane production by Arctic peat microbiota in response to warming
Arctic permafrost soils store large amounts of soil organic carbon (SOC) that could be
released into the atmosphere as methane (CH4) in a future warmer climate. How warming …
