Nitrogen isotopic fractionation associated with growth on dinitrogen gas and nitrate by cyanobacteria
Nitrogen isotopic fractionation associated cyanobacteria
2014/4/18
This study investigated the bulk nitrogen isotopic composition and fractionation of marine and freshwater
cyanobacteria growing at the expense of atmospheric dinitrogen gas (N2) or nitrate (NO{

Natural isotopic composition of carbon (d13 C) correlates with colony size in the planktonic cyanobacterium Gloeotrichia echinulata
Natural isotopic colony size
2014/4/18
To assess variability in carbon isotope signatures (d13
C) between and within populations under natural
conditions, with a particular emphasis on colony size, we repeatedly collected planktonic colo...
Carbon and hydrogen isotopic compositions of sterols from riverine and marine sediments
Carbon hydrogen isotopic compositions

The sources (marine algae, terrestrial C3 and C4 plants) of sterols deposited to sediments along a riverine–marine
transect from Ohtsuchi River in Iwate Prefecture, Japan, to the northwestern Paci...
Nitrogen isotopic evidence for micronutrient control of fractional NO utilization in the 2 3 equatorial Pacific
fractional NO utilization Nitrogen isotopic evidence
