Diversity trumps acidification : lack of evidence for carbon dioxide enhancement of Trichodesmium community nitrogen or carbon fixation at Station ALOHA

Creator:

Gradoville, Mary R., White, Angelicque E., Böttjer, Daniela, Church, Matthew J., and Letelier, Ricardo M.

Abstract:

We conducted 11 independent short-term carbon dioxide (CO₂) manipulation experiments using colonies of the filamentous cyanobacteria Trichodesmium isolated on three cruises in the North Pacific Subtropical Gyre (NPSG). Dinitrogen (N₂) and carbon (C) fixation rates of these colonies were compared over CO₂ conditions ranging from ~ 18 Pa (equivalent to...

Flexible elemental stoichiometry in Trichodesmium spp. and its ecological implications

Creator:

White, Angelicque E., Spitz, Yvette, Karl, David, and Letelier, Ricardo M.

Abstract:

We conducted laboratory experiments to assess the bioelemental plasticity of cultures of Trichodesmium IMS101 under phosphorus (P)-replete, P-restricted, and light-limited conditions. The results reveal a high degree of stoichiometric flexibility. Specifically, Trichodesmium IMS101 is capable of growth with carbon (C) : nitrogen (N) : P ratios of C₅₈₅±₅₆ : N₉₀±₁₀...
