Journal ArticleDOI
Every base matters: assessing small subunit rRNA primers for marine microbiomes with mock communities, time series and global field samples
TL;DR: It is shown that beyond in silico predictions, testing with mock communities and field samples is important in primer selection, and a single mismatch can strongly bias amplification, but even perfectly matched primers can exhibit preferential amplification.
Journal ArticleDOI
Marine microbial community dynamics and their ecological interpretation
TL;DR: This Review summarizes the current understanding of marine microbial community dynamics at various scales, from hours to decades, and explains how the data illustrate community resilience and seasonality, and reveal interactions among microorganisms.
Journal ArticleDOI
Pronounced daily succession of phytoplankton, archaea and bacteria following a spring bloom
David M. Needham,Jed A. Fuhrman +1 more
TL;DR: Extending beyond the traditional view of blooms being controlled primarily by physics and inorganic nutrients, these dynamics imply highly heterogeneous, continually changing conditions over time and/or space and suggest that interactions among microorganisms are critical in controlling plankton diversity, dynamics and fates.
Journal ArticleDOI
Metabolic and biogeochemical consequences of viral infection in aquatic ecosystems.
Amy E. Zimmerman,Cristina Howard-Varona,David M. Needham,Seth G. John,Alexandra Z. Worden,Alexandra Z. Worden,Matthew B. Sullivan,Jacob R. Waldbauer,Maureen L. Coleman +8 more
TL;DR: There is a need for understanding viral infection dynamics in realistic physiological and environmental contexts to better predict their biogeochemical consequences, and metabolic reprogramming of host cells during viral infection alters the flow of energy and nutrients in aquatic ecosystems.
Journal ArticleDOI
Seasonal and interannual variability of the marine bacterioplankton community throughout the water column over ten years.
Jacob A. Cram,Cheryl-Emiliane T. Chow,Rohan Sachdeva,David M. Needham,Alma E. Parada,Joshua A. Steele,Jed A. Fuhrman +6 more
TL;DR: This surface-to-bottom, decade-long, study identifies seasonality and interannual variability not only of overall community structure, but also of numerous taxonomic groups and near-species level operational taxonomic units.
