This year marked the first Human and Environmental Microbiome Symposium organized by the Duke Center for Genomics of Microbial Systems (GeMS). Both the Johnson Lab and the Hunt Lab traveled to the Durham campus to present research concerning marine microbes, and to learn about other microbial research going on in […]

Time series studies have shown that some bacterial taxa occur only at specific times of the year while others are ubiquitous in spite of seasonal shifts in environmental variables. Here, we ask if these ubiquitous clades are generalists that grow over a wide range of environmental conditions, or clusters […]
Transitions in community genomic features and biogeochemical processes were examined in surface and subsurface chlorophyll maximum (SCM) microbial communities across a trophic gradient from mesotrophic waters near San Diego, California to the oligotrophic Pacific. Transect end points contrasted in thermocline depth, rates of nitrogen and CO2 uptake, new production and […]
The biodiversity of phytoplankton is a core measurement of the state and activity of marine ecosystems. In the context of historical approaches, we review recent major advances in the technologies that have enabled deeper characterization of the biodiversity of phytoplankton. In particular, high-throughput sequencing of single loci/genes, genomes, and communities […]
Fungi contribute substantially to biogeochemical cycles of terrestrial and marine habitats by decomposing matter and recycling nutrients. Yet, the diversity of their planktonic forms in the open ocean is poorly described. In this study, culture-independent and molecular approaches were applied to investigate fungal diversity and abundance derived from samples collected […]
The Marine Microbe Group (Johnson and Hunt Labs) at the Duke Marine Laboratory has been awarded a NSF project (#1416665) to study the effects of ocean acidification on microbes. Titled, ‘Collaborative Research: Ocean Acidification: microbes as sentinels of adaptive responses to multiple stressors: contrasting estuarine and open ocean environments,‘ the […]
It’s not a new NASCAR event! The Pivers Island Coastal Observatory (PICO) logged its 600th time point today. The observatory, which was originally established to monitor ocean acidification, now includes a suite of physical, chemical and biological measurements made at least weekly throughout the year towards understanding coastal ocean variability […]
Members of the Johnson Lab headed to Pivers Island dock to participate in Ocean Sampling Day on the summer solstice again this year. The Johnson Lab and the Hunt Lab at DUML were one of the 185 marine research sites from around the world that registered for Ocean Sampling Day 2014. Researchers provided data […]
On a beautiful Spring day, the Johnson Lab welcomed alumni, town visitors and many others for the official opening ceremony of the Pilkey Research Building. The new building, the first research laboratory at the Duke Marine Lab in over 50 years, is a state-of-the-art facility that embraces the beauty of […]
