Ecology and Environmental Controls of Two Keystone Groups of Oceanic Microorganisms : Diazotrophs and Pathogenic Vibrio

Creator:

Gradoville, Mary Rose

Abstract:

Marine bacteria play vital roles in every niche of the ocean, from small-scale symbioses to large-scale productivity and the regulation of Earth’s climate. Recent advances in molecular tools now allow us to probe the genetic potential of entire microbial communities. The next step is linking these diverse communities to the...

A study on the effects of enhanced pCO2 on open ocean diazotrophic assemblages

Creator:

Gradoville, Mary Rose

Abstract:

Biological di-nitrogen (N₂) fixation is a key process in open-ocean ecosystems, where the new nitrogen (N) provided by marine diazotrophs can support a large fraction of primary productivity and carbon (C) drawdown. Recent laboratory studies have shown that elevated pCO₂ enhances the rate of N₂ fixation by select laboratory isolates...
