Metal accumulation by heterotrophic marine bacterioplankton
heterotrophic marine bacterioplankton Metal accumulation
2014/4/16
Radioisotopes of six metals (54Mn, 55
Fe, 65
Zn, 109
Cd, 137
Cs, and 241Am) were used to assess the accumulation
of these metals by five species of heterotrophic marine bacteria in laboratory cul...
The effect of temperature on the coupling between phosphorus and growth in lacustrine bacterioplankton communities
The effect of temperature coupling between phosphorus growth in lacustrine bacterioplankton communities
2014/4/18
Phosphorus (P) routinely limits microbial growth in freshwater ecosystems. The growth rate hypothesis (GRH) relates growth to biomass P content mechanistically through changes in ribosomal ribonucleic...
Enhanced viral production and infection of bacterioplankton during an iron-induced phytoplankton bloom in the Southern Ocean
Enhanced viral production infection of bacterioplankton iron-induced phytoplankton bloom Southern Ocean
2014/4/18
We followed the viral response to Fe-enrichment over 3 weeks during the second iron-enrichment experiment (EisenEx) in the Southern Ocean. Although viral abundance increased in a rather constant way d...
Contrasting the influences of stream inputs and landscape position on bacterioplankton community structure and dissolved organic matter composition in high-elevation lake chains
Contrasting landscape position
2014/4/18
We examined bacterioplankton community composition (BCC; using polymerase chain reaction-based
phylogenetic fingerprinting) and the composition of dissolved organic matter (DOM; using scanning fluoro...

Significant year-round effect of small mixotrophic flagellates on bacterioplankton in an oligotrophic coastal system
Significant year-round effect small mixotrophic flagellates bacterioplankton oligotrophic coastal system
2014/4/22
The seasonal variation in the grazing effect of mixotrophic flagellates on bacterioplankton was assessed during an annual cycle in an oligotrophic coastal station in the northwest Mediterranean Sea. I...
Bacterioplankton community in Chesapeake Bay: Predictable or random assemblages
Bacterioplankton community Chesapeake Bay Predictable random
2014/5/5
We monitored bacterioplankton communities from Chesapeake Bay over 2 years (2002-2004) by use of denaturing gradient gel electrophoresis (DGGE) of PCR-amplified 16S rRNA gene. Chesapeake Bay bacteriop...
Response of Southern Ocean phytoplankton and bacterioplankton production to short-term experimental warming
Southern Ocean phytoplankton bacterioplankton production short-term experimental warming
2014/5/4
We examined the potential response of Southern Ocean pelagic ecosystems to warming through changes in total primary production (particulate plus dissolved = PPP + DPP) and bacterial production (BP), d...
Remarkable heterogeneity in meso- and bathypelagic bacterioplankton assemblage composition
Remarkable heterogeneity in meso bathypelagic bacterioplankton assemblage composition
2014/5/4
We investigated meso- to bathypelagic (500-3,000 m) bacterioplankton assemblage composition at 19 locations in the North Atlantic Ocean beneath the offshore Amazon River plume, in the North Pacific Oc...
Testing the effect of CO2 concentration on the dynamics of marine heterotrophic bacterioplankton
CO2 concentration marine heterotrophic bacterioplankton
2014/4/23
To date no study exists that directly addresses changes in dynamics of heterotrophic bacteria in surface waters
in relation to partial pressure of CO2
(pCO2
). Therefore, we studied the effect of c...
