Quantification of zooplankton trophic position in the North Pacific Subtropical Gyre using stable nitrogen isotopes
We quantify the trophic positions of subtropical open-ocean zooplankton species using amino acid–specific (AA) stable nitrogen isotopic compositions. We model animal trophic position by computing trophic 15N enrichment of glutamic acid relative to phenylalanine, and find that trophic position for primary copepod consumers (Oithona spp., Neocalanus robustior) and secondary copepod consumers (Ple...
متن کاملInterannual variability of primary production and dissolved organic nitrogen storage in the North Pacific Subtropical Gyre
[1] The upper ocean primary production measurements from the Hawaii Ocean Time series (HOT) at Station ALOHA in the North Pacific Subtropical Gyre showed substantial variability over the last two decades. The annual average primary production varied within a limited range over 1991–1998, significantly increased in 1999–2000 and then gradually decreased afterwards. This variability was investiga...
متن کاملMicrobiome of Trichodesmium Colonies from the North Pacific Subtropical Gyre
Filamentous diazotrophic Cyanobacteria of the genus Trichodesmium, often found in colonial form, provide an important source of new nitrogen to tropical and subtropical marine ecosystems. Colonies are composed of several clades of Trichodesmium in association with a diverse community of bacterial and eukaryotic epibionts. We used high-throughput 16S rRNA and nifH gene sequencing, carbon (C) and...
متن کاملDissolved hydrogen and nitrogen fixation in the oligotrophic North Pacific Subtropical Gyre
The production of hydrogen (H2) is an inherent component of biological dinitrogen (N2) fixation, and there have been several studies quantifying H2 production relative to N2 fixation in cultures of diazotrophs. However, conducting the relevant measurements for a field population is more complex as shown by this study of N2 fixation, H2 consumption and dissolved H2 concentrations in the oligotro...
متن کاملExperiments linking nitrogenase gene expression to nitrogen fixation in the North Pacific subtropical gyre
We examined diazotroph activity in controlled experiments containing natural populations of nitrogen (N2)fixing microbes collected offshore from Kane’ohe Bay, Hawai’i, and from Station ALOHA (A Long-term Oligotrophic Habitat Assessment) in the North Pacific subtropical gyre. Quantitative polymerase chain reaction and reverse transcription-polymerase chain reaction approaches showed that the abu...
