Ocean acidification and nitrification

July 14, 2014

Ammonia-oxidizing archaea (AOA) play a key role in marine nitrogen cycle and are known as a major contributor to N2O release and plausible indirect source of methane in the upper ocean. Thus, their sensitivity to ocean acidification and other physicochemical changes associated with climate change has global significance.
Although marine nitrification driven by AOA were reported as highly sensitive to reduction in ocean pH, our new paper published in PNAS (July 11, 2014) show that some coastal marine AOA can remain active with increasing acidification of the oceans.

Priceless for his dedicated effors in 100 hrs of his lab work!

September 10, 2014

I sincerely thank Aaron Sipos to his great contribution in our laboratory.  He deeply loves marine life and aquarium science.  He has been engaged in the study of nitrifying microorganisms in my lab. His passion, great ideas and thoughts are nicely topped on his efforts.  He continues to work in his senior project (summer B, 2014) and is trying to wrap up his methylene blue toxicity experiments.  Now he challenges writing a paper about methylene blue toxicity to nitrifying archaea and bacteria.  I believe his finding will be a great benefit for many aquarists in the future.  Now his lab work reached 100 hours.  Congratulations!

 

His work was published in 2016.

Influence of freshwater discharge in the microbial degradation processes of dissolved organic nitrogen in a subtropical estuary

May 22, 2014

Congratulations to graduate student Juan Garcia for earning The FASEB MARC Travel Award to attend  the 114th American Society for Microbiology General Meeting on May 17-20 2014, Boston, MA for his presentation entitled "Influence of Freshwater Discharge in the Microbial Degradation Processes of Dissolved Organic Nitrogen in a Subtropical Estuary", Juan Garcia as a lead presenter.

 

The FASEB MARC Program provides funding for travel awards to encourage and support the participation of underrepresented students and postdoctoral fellows at scientific meetings and conferences, and the participation of underrepresented PhD/graduate students, postdoctoral fellows and faculty members in leadership development and grantsmanship training seminar programs.  See more at: http://www.faseb.org/MARC-and-Professional-Development/Travel-Awards.aspx#sthash.3juNGz9E.dpuf

Later his research was published in a peer-reviewed journal.

Plant Ecology: Florida scrub and wild fire-plant interactions

May 15, 2014

Dr. Eric S. Menges, Director of Plant Ecology Program and Senior Research Biologist at Archbold Biological Station visited us. He attended a Florida native plant conference at FGCU and stopped by AB7 building on May 15, 2014.  He is a well-known plant ecologist who studies Florida scrub and wild fire-plant interactions.  Florida schrub is a unique plant community characterized by the dominance of shrubs and occurs in small patches scattered across the state. It can be found on elevated dunes along the Florida coastline or inland part along sandy ridges of the peninsula. Florida Scrub serves as a valuable home to dozens of plant and animal species that have adapted to life in the scrub and found nowhere else.  It was a great opportunity to know about this unique and interesting ecosystem. 

Phenotypic and genotypic features of Nitrosospira lacus sp. nov., an ammonia-oxidizing bacterium isolated from lake sediment

April 16, 2013

Congratulations to graduate student Juan Garcia for earning the 2nd place graduate oral presentation award at the Annual Meeting of the Florida Branch of the American Society for Microbiology in Islamorada, FL for his talk about genome sequencing analysis of Nitrosospira lacus, a new ammonia-oxidizing bacterium! (April 12-14, 2013)

​

Later presented results were published in two papers.

Toshi Urakawa, Professor of Environmental Science

Toshi Urakawa joined the Department of Marine and Ecological Sciences at FGCU in 2010. His fields of interest are environmental cleanup technology and biodiversity. After completing his doctoral degree with a study of cold-loving (psychrophilic/psychrotolerant) marine microorganisms and systematics of Vibrionaceae at the University of Tokyo, he continued his research as a postdoctoral researcher in Dave Stahl’s lab in Northwestern University and the University of Washington. In these places, he studied molecular microbial ecology. In his early professional carriers, he studied the nitrogen cycle and the problem of eutrophication and dead zone (i.e. oxygen depletion) at the National Institute for Environmental Studies (Japanese EPA) and the University of Tokyo in Japan. Before joining FGCU, he studied ammonia-oxidizing archaea and genomics in Dave Stahl’s lab at UW for a better understanding of the nitrogen cycle. At FGCU, he studies biogeochemical cycles in southwest Florida and biological and engineering water qualification technology as reducing means of human disturbance of aquatic environments. Recently he initiated conservation biology studies. Toshi teaches marine science classes, general ecology, and microbial ecology at FGCU.

Taylor Hancock, Post-Graduate Laboratory Assistant

Taylor graduated FGCU with a Bachelor’s degree in Biology in Fall 2016 and then with a Environmental Science Master’s degree in Spring of 2019 receiving distinction as FGCU's Graduate Student of the Year. His thesis work involved studying the feeding behavior and diet of smalltooth sawfish through genetic analysis to identify prey items at the species-level in hopes of furthering conservation efforts of this endangered ray. His current projects involve examining fish foragers of the Microcystis aeruginosa harmful algal bloom in the Caloosahatchee River using traditional and molecular methods as well as sequencing the genome of M. aeruginosa and other associated algal species. His research interests include molecular genetics, disturbance ecology, and evolutionary biology.
