A role for programmed cell death in the microbial loop. [PDF]
The microbial loop is the conventional model by which nutrients and minerals are recycled in aquatic eco-systems. Biochemical pathways in different organisms become metabolically inter-connected such that nutrients are utilized, processed, released and ...

Shift from Carbon Flow through the Microbial Loop to the Viral Shunt in Coastal Antarctic Waters during Austral Summer [PDF]
The relative flow of carbon through the viral shunt and the microbial loop is a pivotal factor controlling the contribution of secondary production to the food web and to rates of nutrient remineralization and respiration.

Bacterial, Phytoplankton, and Viral Distributions and Their Biogeochemical Contexts in Meromictic Lake Cadagno Offer Insights into the Proterozoic Ocean Microbial Loop [PDF]
Lake Cadagno, a permanently stratified high-alpine lake with a persistent microbial bloom in its chemocline, has long been considered a model for the low-oxygen, high-sulfide Proterozoic ocean.

A light-induced shortcut in the planktonic microbial loop. [PDF]
AbstractMixotrophs combine photosynthesis with phagotrophy to cover their demands in energy and essential nutrients. This gives them a competitive advantage under oligotropihc conditions, where nutrients and bacteria concentrations are low. As the advantage for the mixotroph depends on light, the competition between mixo- and heterotrophic bacterivores

Phylogenetically conserved resource partitioning in the coastal microbial loop. [PDF]
Abstract Resource availability influences marine microbial community structure, suggesting that population-specific resource partitioning defines discrete niches. Identifying how resources are partitioned among populations, thereby characterizing functional guilds within the communities, remains a challenge for microbial ecologists.

Is there a Microbial Loop in Lake Baikal? [PDF]
The occurrence of a microbial loop in the pelagic environment is discussed with regard to hydrological and meteorological effects as well as to the planktological states during the seasons in lake Baikal.

Incorporating the microbial loop in a simple plankton model [PDF]
The microbial loop, which recycles nutrients in the upper layers of the ocean, is an integral part of plankton dynamics. The usual method for modelling the complex patterns involved has been to consider the ‘Z’ in N/P/Z (nutrient/phytoplankton/zooplankton) models as containing all possible grazers on P and, implicitly, relegate the carnivorous ...

Methane- and dissolved organic carbon-fueled microbial loop supports a tropical subterranean estuary ecosystem [PDF]
It remains unclear how oligotrophic habitats in subterranean estuaries sustain complex ecosystems. Here, using stable isotopic evidence from organic matter and pelagic shrimp, the authors show that a microbial loop fuelled by methane and dissolved ...

Microbial dynamics in autotrophic and heterotrophic seawater mesocosms. I. Effect of phytoplankton on the microbial loop [PDF]
The effect of phytoplankton on the other compartments of a simple microbial loop consisting of dissolved matter, bacteria and nanoflagellates was investigated in three 1000 1 mesocosms. These mesocosms were inoculated with a natural bacterial community and (1) no other additions (No Addition tank), (2) Phaeocystis globosa (Phaeocystis tank), or (3) 2 ...

The inverted microbial loop stimulates mineralisation of sedimentary organic detritus [PDF]
Respiration is a key process in the organic carbon cycle of marine sediments, the understanding of which is key to future management decisions which aim to maximise sediment carbon storage.
