Trichodesmium– a widespread marine cyanobacterium with unusual nitrogen fixation properties
The last several decades have witnessed dramatic advances in unfolding the diversity and
commonality of oceanic diazotrophs and their N2-fixing potential. More recently, substantial …

Aquatic and terrestrial cyanobacteria produce methane
Evidence is accumulating to challenge the paradigm that biogenic methanogenesis,
considered a strictly anaerobic process, is exclusive to archaea. We demonstrate that …

[ספר][B] Guide to best practices for ocean acidification research and data reporting
U Riebesell, VJ Fabry, L Hansson, JP Gattuso - 2011 - oceanrep.geomar.de
Ocean acidification is an undisputed fact. The ocean presently takes up one-fourth of the
carbon CO2 emitted to the atmosphere from human activities. As this CO2 dissolves in the …

Methodological underestimation of oceanic nitrogen fixation rates
The two commonly applied methods to assess dinitrogen (N2) fixation rates are the 15N2-
tracer addition and the acetylene reduction assay (ARA). Discrepancies between the two …

The Toxicity of Copper to Crocosphaera watsonii and Other Marine Phytoplankton: A Systematic Review
The cupric ion (Cu2+) plays a dual role as both nutrient and toxicant to freshwater and
marine phytoplankton, functioning in multiple photochemical processes, as well as reactive …

High rates of N2 fixation by unicellular diazotrophs in the oligotrophic Pacific Ocean
The availability of nitrogen is important in regulating biological productivity in marine
environments. Deepwater nitrate has long been considered the major source of new …

Sinking Trichodesmium fixes nitrogen in the dark ocean
The photosynthetic cyanobacterium Trichodesmium is widely distributed in the surface low
latitude ocean where it contributes significantly to N2 fixation and primary productivity …

Iron availability, cellular iron quotas, and nitrogen fixation in Trichodesmium
Iron availability is suggested to be a primary factor limiting nitrogen fixation in the oceans.
This hypothesis is principally based on costߚbenefit analyses of iron quotas in the dominant …

General characteristics of the cyanobacteria
RW Castenholz - Bergey's Manual of Systematics of Archaea …, 2015 - Wiley Online Library
Apart from sharing the basic cellular features of other Bacteria, the cyanobacteria possess
unique and diagnostic characteristics that will be briefly described here, but less extensively …

Controlled motility in the cyanobacterium Trichodesmium regulates aggregate architecture
The ocean's nitrogen is largely fixed by cyanobacteria, including Trichodesmium, which
forms aggregates comprising hundreds of filaments arranged in organized architectures …
