Graphical coding data and operational guidance for implementation or modification of a LabVIEW®-based pHstat system for the cultivation of microalgae

Creator:: Golda, Rachel L., Needoba, Joseph A., Golda, Mark D., and Peterson, Tawnya D.
Abstract:: The influence of pH on phytoplankton physiology is an important facet of the body of research on ocean acidification. We provide data developed during the design and implementation of a novel pHstat system capable of maintaining both static and dynamic pH environments in a laboratory setting. These data both help...

Activity and phylogenetic diversity of bacterial cells with high and low nucleic acid content and electron transport system activity in an upwelling ecosystem

Creator:: Longnecker, K., Sherr, Barry F., and Sherr, Evelyn
Abstract:: We evaluated whether bacteria with higher cell-specific nucleic acid content (HNA) or an active electron transport system, i.e., positive for reduction of 5-cyano-2,3-ditolyl tetrazolium chloride (CTC), were responsible for the bulk of bacterioplankton metabolic activity. We also examined whether the phylogenetic diversity of HNA and CTC-positive cells differed from the...

Changing the culture of coastal, ocean, and marine sciences : strategies for individual and collective actions

Creator:: Behl, Mona, Cooper, Sharon, Garza, Corey, Kolesar, Sarah E., Legg, Sonya, Lewis, Jonathan C., White, Lisa, and Jones, Brandon
Abstract:: Geoscience is plagued with structural and systemic barriers that prevent people of historically excluded groups from fully participating in, contributing to, and accruing the benefits of geosciences. A change in the culture of our learning and working environments is required to dismantle barriers and promote belonging, accessibility, justice, equity, diversity,...

Effect of protistan grazing on the frequency of dividing cells in bacterioplankton asemblages

Creator:: Sherr, Barry F., Sherr, Evelyn, and McDaniel, Julie
Abstract:: Grazing by phagotrophic flagellates and ciliates is a major source of mortality for bacterioplankton in both marine and freshwater systems. Recent studies have demonstrated a positive relationship between clearance rate and prey size for bacterivorous protists. We tested the idea that, by selectively grazing the larger (more actively growing or...

Investigating Microbial Eukaryotic Diversity from a Global Census: Insights from a Comparison of Pyrotag and Full-Length Sequences of 18S rRNA Genes

Creator:: Lie, Alle A. Y., Liu, Zhenfeng, Hu, Sarah K., Sherr, Evelyn B., Sherr, Barry F., Jones, Adriane C., Kim, Diane Y., Countway, Peter D., Amaral-Zettler, Linda A., Cary, S. Craig, Gast, Rebecca J., and Caron, David A.
Abstract:: Next-generation DNA sequencing (NGS) approaches are rapidly surpassing Sanger sequencing for characterizing the diversity of natural microbial communities. Despite this rapid transition, few comparisons exist between Sanger sequences and the generally much shorter reads of NGS. Operational taxonomic units (OTUs) derived from full-length (Sanger sequencing) and pyrotag (454 sequencing of...

The effects of infaunal biodiversity on biogeochemistry of coastal marine sediments

Creator:: Waldbusser, George G., Marinelli, Roberta L., Whitlatch, Robert B., and Visscher, Pieter T.
Abstract:: We tested the role of benthic infaunal functional diversity in regulating the biogeochemistry of nearshore sediments using laboratory microcosms. Single and multispecies assemblages of deposit-feeding polychaetes (Clymenella torquata, Spio setosa, and Leitoscoloplos fragilis) were used, and fluxes of oxygen and phosphate, as well as profiles of oxygen and pH in...

A new method for estimating growth rates of alkenone-producing haptophytes

Creator:: Popp, Brian N., Bidigare, Robert R., Deschenes, Bryan, Laws, Edward A., Prahl, Fredrick, Tanimoto, Jamie K., and Wallsgrove, Richard J.
Abstract:: Laboratory culture experiments were performed to establish the range of growth conditions where ¹³C labeling of di- and tri-unsaturated C₃₇ methyl ketones yields reliable growth rates for alkenone-producing algae. Results document that even at low growth rates and short time intervals, ¹³C labeling of the di-unsaturated C₃₇ alkenone provides reasonable...
