New publication in Journal of Phycology!

May 10, 2017

Our new publication was published online in Journal of Phycology Early View.  In this study we have developed a molecular indicator to determine the iron status of Pseudo-nitzschia within natural diatom assemblages using gene expression.  As part of this study, we have created an online tool to calculate the Pseudo-nitzschia Iron Limitation Index (ILI) from metatranscriptomic sequence data sets.

The Pseudo-nitzschia ILI Calculator is available here.

New publication in Limnology and Oceanography!

April 21, 2017

Our new publication by Natalie Cohen and coauthors was published online in Limnology and Oceanography.  In this study we have examined co-limitation of iron and vitamins within diatom isolates and natural diatom assemblages from the Northeast Pacific Ocean.  It appears that diatoms need their vitamins too!

New publication in ISME J!

Dec. 9, 2016

Our new publication by Weida Gong and coauthors was published online in ISME Journal.  In this study we have applied a metatranscriptomic approach to examine gene expression during a dinoflagellate bloom in the Neuse River Estuary.

New publication in Protist!

Dec. 9, 2016

Our new publication by former Masters student Kelsey Ellis and coauthors was published online today in the journal Protist.  This study investigates the vitamin B12 requirements in diatoms.

New publication in Frontiers in Marine Science!

June 30, 2016

We have a new paper published in Frontiers in Marine Science that analyzes the transcriptomic response of the resilient coral Siderastrea siderea to long term thermal and ocean acidification stresses.  Hopefully this will be the first of many publications from the Marchetti Lab studying climate change effects on corals and their associated algal symbionts.  The lead author is Sarah Davies and co-authors include Adrian, Justin Ries (NEU) and Karl Castillo.

Moreno in Antarctica!

January 13, 2016

IMG_1414Ph.D. student Carly Moreno is participating on the PalmerLTER research cruise in Antarctica. For the next 6 weeks, Carly will be collecting samples and performing incubation experiments to investigate the environmental factors that regulate phytoplankton growth by using molecular sequencing approaches.   She is also collecting measurements of biogenic gases using an underway mass spectrometer as part of a collaboration with the Cassar Lab at Duke University. Stay warm Carly!

More information about the PalmerLTER can be found here.
