Victoria Suarez-Ulloa defended her PhD dissertation last week with perfect scores!, this completes a very productive stage in her academic trajectory with 10 papers published, several presentations in international conferences and most importantly, a postdoctoral position already lined up in Europe to continue working with population epigenomics. Vicky, we’re really proud of you and wish you the best for the future!!!

congratulations to Chromevol undergrad Michelot Michel

Our own Michelot Michel (Biology senior) has been awarded with the Exemplary Service Award from the College of Arts, Sciences and Education, congrats!!! Michelot is also one of the finalists for the Outstanding Student Life Awards that will be announced tomorrow evening in a gala dinner and also for the Cuervo Prize awarded by FIU’s Biology Department. If all of that is not enough, Michelot is giving the final touches to his Honors dissertation, focused on the epigenetic responses of the flat tree oyster Isgonomon alatus to seasonal changes in Northern Biscayne Bay. Michelot will be defending his dissertation on April 17th at WC130, MMC Campus, FIU. We all look forward for a great presentation!

Eastern oyster epigenetics work accepted in Aquatic Toxicology!

Posted by | DNA, Epigenetics, FIU, Histones, Marine Biology, Oysters, Red Tides, Toxicology | No Comments

Our latest work “Effects of Florida Red Tides on histone variant expression and DNA methylation in the Eastern oyster Crassostrea virginica” has been accepted for publication in the journal Aquatic Toxicology (3.557 impact factor, ranked 3/104 in Marine & Freshwater Biology). The unformatted version of the paper is available at http://www.sciencedirect.com/science/article/pii/S0166445X17300760 and HERE. This work was developed by our lab at FIU (Environmental Epigenetics group, Dept. Biology, Institute of Water and Environment, CREST Center for Aquatic Chemistry and Environment) in collaboration with the Ecotoxicology Lab (SERC) and the University of Vigo, in Spain. We also collaborated with Rookery Bay National Estuarine Research Reserve during this research. Our results provide a basis to better understand how Florida Red Tides affect oysters and epigenetic mechanisms participating in their responses to environmental stress, opening new avenues to incorporate environmental epigenetics approaches into management and conservation programs. We are currently building on this work in collaboration with Mote Marine Lab as well as with aquaculture stakeholders in south and central Florida.

Last week we had the chance of participating in a session focused on environmental epigenetics in the world congress of the Society of Environmental Toxicology and Chemistry. It was really great to see so many people interested in using epigenetic approaches to address environmental problems, involving a wide range of new model organisms encompassing environmental and ecological relevance. From our side, we presented works investigating the epigenetic modifications involved in responses to Florida Red tides in Eastern oysters (talk by Dr. Eirin-Lopez), the different genetic networks activated during responses (Victoria Suarez-Ulloa) as well as the first results from our most recent efforts to elucidate the epigenetic mechanisms underlying coral responses to nutrient stress in the ocean (Javier Rodriguez-Casariego). Overall, we left with a great feeling and looking forward to see environmental epigenetics grow and its links with ecology, toxicoloy and physiology being further explored in the future!img_4039

Dr. Eirin-Lopez joins the journal Agri Gene as Associate Editor

Posted by | Chromatin, Epigenetics, Genetics, Research | No Comments

Agri Gene publishes papers that focus on the regulation, expression, function and evolution of genes in crop plants, farm animals, and agriculturally important insects and microorganisms. Agri Gene strives to be a diverse journal and topics in multiple fields will be considered for publication so long as their main focus is on agriculturally important organisms (plants, animals, insects, or microorganisms). Although not limited to the following, some examples of potential topics include:

Gene discovery and characterization.
Genetic markers to guide traditional breeding.
Genetic effects of transposable elements.
Evolutionary genetics, molecular evolution, population genetics, and phylogenetics.
Profiling of gene expression and genetic variation.
Biotechnology and crop or livestock improvement.
Genetic improvement of biological control microorganisms.
Genetic control of secondary metabolic pathways and metabolic enzymes of crop pathogens.
Transcription analysis of beneficial or pest insect developmental stages.

Dr. Eirin-Lopez will be presenting the conference “The Epigenetics Revolution Reaches the Ocean” next Friday, April 15th, at the Murray E. Nelson Government Center in Key Largo, FL. A meet & greet will take place at 6 pm, followed by the conference at 7 pm. We’re looking forward to meet our Friends Of The Key Largo Cultural Center.

 

New Ph.D. student Javier Rodriguez Casariego joins Chromevol next fall

Posted by | Epigenetics, FIU, Genetics, Graduate student, Marine Biology, Oysters, Red Tides, Toxicology | No Comments

Javier graduated from the University of Havana, Cuba (B.S. Biology, 2008; M.S. Marine Biology, 2012) and has worked as a research scientist for the Marine Research Center at this institution until his transition to FIU. During the last 2 years he acted as senior research technician for FIU’s Ecotoxicology Laboratory before joining the Biology Graduate program. Javier is already participating in several Chromevol projects examining environmental epigenetic responses in marine invertebrates. His collaboration has been instrumental for the simulation of HAB episodes using Eastern oysters last summer (he presented preliminary results about this work in the Biosymposium last month), as well as for the analysis of coral samples exposed to nutrient loading. Those preliminary results will constitute the conceptual basis for his Ph.D. project. Welcome!!!

Meet new graduate student Andria Beal

Posted by | Education, Epigenetics, FIU, Graduate student, Marine Biology, Research | No Comments

We have a new Ph.D. student joining us next fall!!! We are excited to welcome Andria Beal to the group! Andria got her Bachelors of Science in Biology at Tarleton State University (2014) and will be getting her Masters of Science in Biology from Texas Christian University in Fort Worth, Texas, this spring. Andria is already working on the outline of her Ph.D. project, involving sharks, stable isotopes and epigenetics. Really cool stuff! Welcome to sunny Florida Andria!
