Seasonal analysis of protistan community structure and diversity at the USC Microbial Observatory (San Pedro Channel, North Pacific Ocean)
protistan community structure USC Microbial Observatory
2014/4/17
The structure and genetic diversity of marine protistan assemblages were investigated in the upper 500 m of the
water column at a Pacific Ocean time-series station off the coast of Southern Californi...
Effect of zooplankton-mediated trophic cascades on marine microbial food web components (bacteria, nanoflagellates, ciliates)
zooplankton-mediated trophic marine microbial food
2014/4/17
To examine the grazing effects of copepod-dominated mesozooplankton on heterotrophic microbial
communities, four mesocosm experiments using gradients of zooplankton abundance were carried out at a
c...
Microbial oceanography of the dark ocean’s pelagic realm
Microbial oceanography dark ocean’s pelagic realm
2014/4/17
The pelagic realm of the dark ocean represents a key site for remineralization of organic matter and long-term
carbon storage and burial in the biosphere. It contains the largest pool of microbes in ...
Vitamin B12 and cobalt cycling among diatoms and bacteria in Antarctic sea ice microbial communities
Vitamin B12 cobalt cycling among diatoms
2014/4/21
Within McMurdo Sound’s annual sea ice, assimilation and concentrations of vitamin B12 (cobalamin),
microbial community productivity, and biomass were examined among three 100-m2
quadrats where light...
Benthic microbial and whole-community responses to different amounts of 13 C-enriched algae: In situ experiments in the deep Cretan Sea (Eastern Mediterranean)
Benthic microbial whole-community responses
2014/4/23
The deep eastern Mediterranean Sea is one of the most oligotrophic regions of the world’s oceans and is therefore
highly suitable for investigating the response of a resource-limited deep-sea benthic...
Metabolic and structural response of hyporheic microbial communities to variations in supply of dissolved organic matter
hyporheic microbial communities Metabolic
2014/5/21
Hyporheic sediment bacterial communities were exposed to dissolved organic matter (DOM) from a variety of
sources to assess the interdependence of bacterial metabolism and community composition. Expe...
Silicate and labile DOC interfere in structuring the microbial food web via algal– bacterial competition for mineral nutrients: Results of a mesocosm experiment
Silicate labile DOC interfere
2014/5/20
The effects of organic and inorganic nutrient enrichments on algal–bacterial competition were investigated using
mesocosms. Interactions were followed over 10 d in 12, 3-m3
seawater mesocosms in the...
Fine-scale measurement of diffusivity in a microbial mat with nuclear magnetic resonance imaging
nuclear magnetic resonance imaging Fine-scale measurement
2014/5/30
Noninvasive

H–nuclear magnetic resonance (NMR) imaging was used to investigate the diffusive properties of
microbial mats in two dimensions. Pulsed field gradient NMR was used to acquire im...
Microbial degradation of organic carbon and nitrogen on diatom aggregates
organic carbon nitrogen
2014/5/30
The major pathways of transformation of particulate organic matter by heterotrophic bacteria are respiration and
production of new biomass. Until today only a limited number of studies have measured ...
