Interactive effects of viral and bacterial production on marine bacterial diversity.

Autor: Chiaki Motegi, Toshi Nagata, Takeshi Miki, Markus G Weinbauer, Louis Legendre, Fereidoun Rassoulzadegan

Publikováno v: PLoS ONE, Vol 8, Iss 11, p e76800 (2013)

A general model of species diversity predicts that the latter is maximized when productivity and disturbance are balanced. Based on this model, we hypothesized that the response of bacterial diversity to the ratio of viral to bacterial production (VP

Journal of Plankton Research, 2011, 33 (8), pp.1249-1262. ⟨10.1093/plankt/fbr024⟩

To better understand the seasonal variation in concentrations and accumulation of dissolved organic carbon (DOC) in north-western Mediterranean surface waters, we investigated changes in bacterial abundance, activity (production, BP; respiration, BR;

Association of marine viral and bacterial communities with reference black carbon particles under experimental conditions: an analysis with scanning electron, epifluorescence and confocal laser scanning microscopy

Publikováno v: FEMS Microbiology Ecology. 74:382-396

Black carbon (BC), the product of incomplete combustion of fossil fuels and biomass, constitutes a significant fraction of the marine organic carbon pool. However, little is known about the possible interactions of BC and marine microorganisms. Here,

International audience; The mesopelagic zone is the oceanic region through which carbon and other elements must pass in order to reach deeper waters or the sea floor. However, the food web interactions that occur in the mesopelagic zone are difficult

REVIEW: Extinction of microbes: evidence and potential consequences

Autor: Fereidoun Rassoulzadegan, Markus G. Weinbauer

Publikováno v: Endangered Species Research. 3:205-215

Microbes, i.e. viruses, prokaryotes, protists and fungi are main players in biogeochemical cycles in aquatic and soil systems. As predators, pathogens, commensals and symbionts they are associated with multicellular life forms. Microbes show a dazzli

Harmful Algae, Elsevier, 2005, 4 (5), pp.895-914. ⟨10.1016/j.hal.2004.12.014⟩

The concentration of transparent exopolymeric particles (TEP) was monitored during Phaeocystis globosa blooms that developed in mesocosms under different initial N:P ratios (from N- to P-limited conditions). TEP concentration was measured using the m

Are viruses driving microbial diversification and diversity?

Autor: Markus G. Weinbauer, Fereidoun Rassoulzadegan

Publikováno v: Environmental Microbiology. 6:1-11

Viruses can influence the genetic diversity of prokaryotes in various ways. They can affect the community composition of prokaryotes by 'killing the winner' and keeping in check competitive dominants. This may sustain species richness and the amount

International audience; A simple steady-state model based on P-Limited bacterial growth rate and predator controlled bacterial biomass predicts bacterial production (BP) to be proportional to the square of ciliate biomass (C). Changes in ciliate biom
