Paper published with collaborators on eukaryotic metatranscriptomes
9/29/2021
Using assemblies of polyA-selected eukaryotic metatranscriptomes, Ryan Groussman led an exploration of how 48 marine eukaryotic genera regulate their gene expression over the diel cycle in the North Pacific Subtropical Gyre. Groussman finds that each taxonomic group has a relatively distinct transcriptional fingerprint. Yet, the diel cycle is a critical driver of the coordinated activities found across these various taxa. This study comes from the Simons Foundation SCOPE-Aloha Program. Check out the paper.

Right (B) includes nine smaller plots for specific species like Prymnesium and Florenciella, with sampling time indicated by color dots. Graph conveys data comparison and temporal trends.

Welcome, Laurel!
8/30/2021
We are thrilled to welcome new graduate student Laurel Meke to our group! Laurel comes to us with much expertise in applications of untargeted and targeted LC-MS. She worked at SECIM (Southeastern Center for Integrated Metabolomics) prior to joining our lab, where she gained a great deal of experience with sample preparation, extractions, and general LC-MS troubleshooting. Now, she will apply and expand her chemistry knowledge to address research questions on marine microbes! Her research interests are to understand how the metabolism of red-tide Karenia brevis is influenced by environmental factors and interactions with other microbes. Welcome, Laurel!

Commentary published on marine microbial interactions
8/24/2021
As part of an early-career researcher series in mSystems, Durham was invited to write a commentary on marine microbial interactions. She outlines current research and future directions to examine microbial cooperation and metabolic exchange in the surface ocean. Check out the paper!

Welcome Emily!
6/2/2021
We have a new lab member – Emily Kracht! Emily graduated from UF in Spring 2021 with degrees in Chemistry & Anthropology. During her undergraduate research at the Florida Museum, she used mass spec tools to analyze ceramics from Caribbean regions. We are thrilled for her to apply her MS knowledge and chemistry background to the world of marine metabolites! Welcome!

2X the metabolomics with colleagues
5/4/2021
Two marine metabolomics manuscripts led by UW colleagues Angie Boysen and Katherine Heal were published in mSystems this month! Boysen et al., show diel oscillations in particulate metabolites consistent with day-night photosynthetic and redox cycles. Heal et al., show how changes in phytoplankton taxonomy shape particulate metabolites along a latitudinal gradient in the North Pacific.  

Figure with two parts illustrating metabolite concentrations and transcript activity over time. Part A shows line graphs of metabolite concentrations including SAH, SAM, and others, plotted from July 26 to 30. Part B displays a scatter plot of transcript peak times with colored circles indicating taxonomic classifications and their functions, annotated with a legend. The graphics convey changes and diversity in metabolic processes.

Congrats to Ashley – 2021 University Scholar
5/3/2021
Ashley has received a 2021 University Scholars Award. Her research project is titled “Determining Preferential Conditions for Phytoplankton Photosynthetic Cycles” where she’ll be looking into the relationship between nitrogen metabolism and photochemistry in marine phytoplankton. Congrats!

Congrats to Mardeliz – off to graduate school!
4/15/2021
Graduating senior Mardeliz Martinez has been accepted to Florida State University’s Biology graduate program. Starting in August, she’ll be working in their Ecology and Evolution Group with Dr. Scott Burgess on coral biology. Congrats!

New paper with collaborators on phytoplankton light sensors!
2/5/2021
Coesel & collaborators through the Simons Foundation SCOPE-Aloha Program have published a new study in PNAS on light sensing in microbial eukaryotes. Using transcriptomes from microbial cultures and metatranscriptomes from the North Pacific surface ocean, Coesel et al. unveil the diversity of light-sensing elements and photoreceptors used by eukaryotic plankton in the open ocean. Ultimately, these receptors synchronize and stabilize plankton patterns of growth, division, metabolism, and mortality within the dynamic ocean environment.

A circular graph showcases diverse photoreceptors and transcription factors across species. Color-coded sections represent groups like Rhodophyta and Chlorophyta. Dots indicate transcript abundance, with larger dots showing higher levels. The diagram's complex, data-dense design conveys scientific analysis and comparison.

Durham awarded SCOPE Scholar Award from Simons Foundation
12/22/2020
Durham has been awarded a one-year award that will support analysis and integration of molecular and oceanographical datasets collected as part of the SCOPE-Gradients Program (SCOPE: Simons Collaboration on Ocean Processes and Ecology). Efforts are focused on understanding how chemical and physical features in the North Pacific influence microbial diversity and activity.

Return to work
8/29/2020
Over the past month, we have made a slow and staged return back into the lab. Much of our time has been spent working with colleagues in ICBR to get the new LC-MS system installed and up-and-running through remote instruction and training. Check out the story by UF Research.

Lab DEI statement
7/1/2020
​During the #ShutDownAcademia #ShutDownSTEM #Strike4BlackLives and #Academics4BlackLives movements, we spent time confronting and reflecting on the historical and systemic racism faced by Black people in our world and in our in educational system. To make the beliefs of our lab group explicit for current and future members, we have written a statement on our diversity, equity, and inclusion values and our commitment to continuous ally-ship.

Inspirational lab poster with bold text: 'In this lab, WE BELIEVE.' Six icons below: microscope (Science is real), rainbow heart (Love is love), raised fist (Black Lives Matter), feminist symbol (Feminism is for everyone), microbes (Microbes are cool), and Statue of Liberty (Immigrants are welcome).

Poster reads: “In this lab, we believe: science is real (microscope image), love is love (rainbow anatomical heart), Black lives matter (brown raised fist), feminism is for everyone (female symbol), microbes are cool (single-celled organisms), immigrants are welcome (statue of liberty).” This poster represents our pledge and commitment to continuous allyship, with original image c/o Sammy Katta (https://sammykatta.com/diversity).

New review article on ocean sulfur cycling
9/4/2019
​Durham & former PhD advisor, Mary Ann Moran at the University of Georgia, have published a review article in Nature Reviews Microbiology entitled “Sulfur metabolites in the pelagic ocean.” The co-authors examine how phytoplankton and bacteria produce & transform sulfur metabolites in the ocean, highlighting the critical role that sulfur plays in mediating microbial interactions and ocean ecosystem function. Link in image.

An infographic illustrates marine microbial exchanges. Diatoms, dinoflagellates, and other phytoplankton release various compounds. Roseobacter and other bacteria uptake these, producing metabolites. Labels highlight metabolic exchanges and processes, set against a stylized ocean background with a sun symbol.
