UGA study finds Saharan dust affects marine bacteria,potential pathogen Vibrio
UGA study Saharan dust marine bacteria pathogen Vibrio
2016/5/19
Iron, a critical element for living organisms, can be hard to hard to come by in open marine waters-except each summer, when atmospherically transported dust from north Africa's Sahara Desert provides...
On the Potential for Bioenergy and Biofuels from Hydrothermal Vent Microbes
Bioenergy Biofuels Hydrothermal Vent Microbes
2015/7/14
The discovery of deep-sea hydrothermal vents caused scientists to reconsider their notions about life in the deep sea. In these seemingly inhospitable environments, free-living microbes, as well as mi...
Advances in Conservation Oceanography: New Tagging and Tracking Technologies and Their Potential for Transforming the Science Underlying Fisheries Management
Conservation Oceanography New Tagging
2015/7/3
Overexploitation of living resources and climate change are among the most obvious global-scale impacts of human society on marine ecosystems. In an age of such large-scale anthropogenic impacts, mari...
Increased cellular brevetoxins in the red tide dinoflagellate Karenia brevis under CO2 limitation of growth rate: Evolutionary implications and potential effects on bloom toxicity
Increased cellular brevetoxins Karenia brevis
2014/4/2
Karenia brevis blooms impair human health, marine ecosystems, and coastal economies in the Gulf of Mexico
via their production of carbon-based neurotoxins (brevetoxins), which contain no nitrogen (N)...
Effects of environmental factors on dimethylated sulfur compounds and their potential role in the antioxidant system of the coral holobiont

2014/4/2
Biogenic dimethylsulfide (DMS) and its main precursors, dimethylsulfoniopropionate (DMSP) and dimethylsulfoxide (DMSO), are potential scavengers of reactive oxygen species in marine algae, and these d...
Metagenomic potential of microbial assemblages in the surface waters of the central Pacific Ocean tracks variability in oceanic habitat
Metagenomic potential microbial assemblages the surface waters the central Pacific Ocean tracks variability oceanic habitat
2014/4/17
Oceanic habitats may select for different organisms, thereby tuning genomic capabilities to local environmental conditions. To understand the relationship between microbial assemblage composition, fun...
Production, dissolution, accumulation, and potential export of biogenic silica in a Sargasso Sea mode-water eddy
Production dissolution accumulation
2014/4/16
Rates of biogenic silica (bSiO2) production, dissolution, accumulation, and potential bSiO2 export were
determined in a Sargasso Sea mode-water eddy (MWE) during two occupations in April 2007. Standi...
Marine Scientists Warn of "Moderately Large" Potential for Spring, Summer Red Tide Outbreak in Gulf of Maine（图）
Moderately Large Gulf of Maine Spring Summer
2009/4/30
The potential for an outbreak of the phenomenon called "red tide" is expected to be moderately large this spring and summer in the Gulf of Maine, according to researchers at the Woods Hole Oceanograph...
Direct measurement of thed13 C signature of carbon respired by bacteria in lakes: Linkages to potential carbon sources, ecosystem baseline metabolism, andCO2fluxes
the d13 C signature bacteria in lakes potential carbon sources ecosystem baseline metabolism CO2 fluxes
2014/4/18
Using a novel method to measure the isotopic signature (d13C) of respiratory CO2 produced by bacterioplankton, we determined the proportion of terrigenous vs. algal-derived organic carbon (OC) respire...

Potential role of copper availability in nitrous oxide accumulation in a temperate lake
copper nitrous oxide accumulation temperate lake
2014/4/22
Denitrifying bacteria require copper for the synthesis of nitrous oxide reductase. In the absence of sufficient bioavailable Cu, nitrous oxide (N2O) may accumulate in natural waters during denitrifica...
The ecological distribution and comparative photobiology of symbiotic dinoflagellates from reef corals in Belize: Potential implications for coral bleaching
ecological distribution comparative photobiology symbiotic dinoflagellates reef corals in Belize coral bleaching
2014/5/4
The photobiology and distribution of dinoflagellates in the genus Symbiodinium was investigated for eight common reef coral species over a depth range of 1-25 m on a coral reef in Belize. The genetic ...
Subitaneous eggs of freshwater copepods pass through fish guts: Survival, hatchability, and potential ecological implications
Subitaneous eggs freshwater copepods pass through fish guts Survival hatchability ecological implications
2014/5/9
We measured the survival of subitaneous eggs of two calanoid (Eudiaptomus gracilis, E. graciloides) and two cyclopoid (Cyclops abyssorum, Macrocyclops albidus) freshwater copepods after they had been ...
