Red Waters of Myrionecta rubra are Biogeochemical Hotspots for the Columbia River Estuary with Impacts on Primary/Secondary Productions and Nutrient Cycles

Creator:

Herfort, Lydie, Peterson, Tawnya D., Prahl, Fredrick G., McCue, Lee Ann, Needoba, Joseph A., Crump, Byron C., Roegner, G. Curtis, Campbell, Victoria, and Zuber, Peter

Abstract:

The localized impact of blooms of the mixotrophic ciliate Myrionecta rubra in the Columbia River estuary during 2007-2010 was evaluated with biogeochemical, light microscopy, physiological, and molecular data. M. rubra affected surrounding estuarine nutrient cycles, as indicated by high and low concentrations of organic nutrients and inorganic nitrogen, respectively, associated...

Herfort, Lydie, Peterson, Tawnya D., McCue, Lee Ann, Crump, Byron C., Prahl, Fredrick G., Baptista, Antonio M., Campbell, Victoria, Warnick, Rachel, Selby, Mikaela, Roegner, G. Curtis, and Zuber, Peter

Abstract:

For several decades, annually recurring blooms of the photosynthetic ciliate Myrionecta rubra have been observed in the Columbia River estuary in late summer. In an effort to understand the dynamics of these blooms, we investigated the genetic variability of M. rubra and its cryptophyte plastids within 3 large estuarine blooms...
