Carbon self-utilization may assist Caulerpa taxifolia invasion
Carbon self-utilization assist Caulerpa taxifolia invasion
2014/4/4
Additions of 13C-labeled macroalgal detritus (Caulerpa taxifolia) and seagrass detritus (Zostera capricorni) to a vegetated intertidal mudflat in subtropical Australia provided insight into the mechan...
Probability Distributions of Breaking Wave Heights Emphasizing the Utilization of the JONSWAP Spectrum
Breaking Wave Heights JONSWAP Spectrum
2009/3/7
An approximate determination has been made of the probability distribution function for breaking wave heights in the deep ocean. It was necessary to make simplifying assumptions of the joint distribut...
3H and 3He in the Beta Triangle：Observations of Gyre Ventilation and Oxygen Utilization Rates
Gyre Ventilation Oxygen Utilization Rates
2009/1/7
Isopycnal maps of 3H–3He age (τ) with about 100 km resolution have been obtained for a 1000-km scale area in the eastern subtropical North Atlantic. The midscale texture of the maps is consistent with...
The cyanate utilization capacity of marine unicellular Cyanobacteria
The cyanate utilization capacity marine unicellular Cyanobacteria
2014/4/21
Cyanate, a by-product of urea decomposition, is a potential nitrogen (N) source in marine environments, but to date it has received scant attention. Cyanobacteria presumably acquire this compound via ...
Physical pathways and utilization of nitrate supply to the giant kelp, Macrocystis pyrifera
Physical pathways utilization of nitrate supply giant kelp, Macrocystis pyrifera
2014/4/18
To determine the relative importance of different sources of nitrate to the annual nitrogen needs of the giant kelpMacrocystis pyrifera,we measured ambient nitrate concentrations at a kelp forest for ...

Photosynthesis and light utilization in the Caribbean coral Montastraea faveolata recovering from a bleaching event
Photosynthesis light utilization
2014/5/5
Coral bleaching—the loss of symbiotic dinoflagellates—is initiated when corals are exposed to sea surface
temperatures above the regional summer average and has been responsible for massive coral mor...
Microbial production, utilization, and enzymatic degradation of organic matter in the upper trophogenic layer in the pelagial zone of lakes along a eutrophication gradient
Microbial production utilization enzymatic degradation
2014/4/30
The major aim of this study was to evaluate the relationships between the rates of microbial activities (phytoplankton primary production, bacterial secondary production, bacterial utilization of orga...
The influence of substratum type and nutrient supply on biofilm organic matter utilization in streams
substratum type nutrient supply
2014/5/19
We investigated the effect of benthic substratum type (sand and rocks) and nutrient supply (N and P) on biofilm
structure and heterotrophic metabolism in a field experiment in a forested ...
D-H fractionation in Sporomusa ORIGINAL ARTICLE Blackwell Publishing, Ltd. Hydrogen isotope fractionation during H2 /CO2 acetogenesis: hydrogen utilization efficiency and the origin of lipid-bound hydrogen
ORIGINAL ARTICLE D-H fractionation
2014/4/8
Hydrogen metabolism was studied in the anaerobic bacterium, Sporomusa sp. strain DMG 58, by measuring
natural abundance levels of deuterium in H2
, H2O, and individual fatty acids during acetogenic ...
Major shift in bacterioplankton utilization of enantiomeric amino acids between surface waters and the ocean's interior
Major shift in bacterioplankton utilization of enantiomeric amino acids between surface waters and the ocean's interior
2014/5/20
The peptidoglycan layer of the bacterioplankton cell wall contains four major amino acids (alanine, Ala; serine, Ser; aspartic acid, Asp; and glutamic acid, Glu) in a characteristic enantiomeric ratio...

Prey resource utilization coexistence hydromedusae Friday Harbor Washington
2014/5/27
Prey selection patterns were quantified for a sympatric group of hydromedusae from Friday Harbor, WA. Selection patterns varied between species, but were largely replicable between sample dates and re...
Utilization of different nitrogen sources by the marine cyanobacteria Prochlorococcus and Synechococcus
different nitrogen sources marine cyanobacteria Prochlorococcus Synechococcus
2014/5/27
Prochlorococcus is the most abundant phytoplankter throughout the photic zone in stratified marine waters and experiences distinct gradients of light and nitrogen nutrition. Physiologically and geneti...
Heterotrophic bacterial utilization of nitrogenous and nonnitrogenous substrates, determined from ammonia and oxygen fluxes
Heterotrophic bacterial utilization nitrogenous non nitrogenous substrates ammonia and oxygen fluxes
2014/6/10
We describe a simple procedure to allow the broad nature of the organic substrates used for planktonic bacterial growth to be determined. The method analyzes the coupled oxygen and ammonia fluxes in t...
