New, effective DNA method for discovering fish spawning grounds

ST. PETERSBURG, FL - Towing a plankton net to scoop up fish eggs may be routine, but determining the species is a different matter altogether.  A collaboration of two labs at the College of Marine Science uses a new method to discover fish spawning grounds through analysis of the DNA in fish eggs. 

The vast majority of fish in the ocean are broadcast spawners –the female releases eggs in large quantities to float around until the larvae hatch and swim away on their own.  A problem facing many fisheries managers is the time it takes to estimate fish populations.  A new method utilizing DNA will likely reduce that time from years to months. 

Dr. Ernst Peebles realized that existing fish population methods could be extended to a much larger number of species through new technologies and new databases like FISH-BOL (fish barcode of life).  With the development of the Marine Resource Assessment program in 2010 here at the college, Dr. Mya Breitbart was eager to collaborate with fisheries ecologists on gaps in the body of research that molecular biology methods might fill. 

A process called DNA barcoding focuses on a segment of DNA that is short enough to be efficiently sequenced but long enough to allow for identification of species.  While most fish eggs look alike, their DNA does not.

Working in one of Dr. Breitbart’s microbiology labs, USFSP senior Makenzie Burrows performs much of the hands-on DNA work related to this project.  Dr. Breitbart explains the process further, “When we sequence this gene, we can then compare it against the database and that tells us what species each fish egg belongs to.”

From the original proof-of-concept study done in small Terra Ceia Bay (near the mouth of Tampa Bay), the DNA barcoding of fish eggs has expanded to cover the entire Gulf of Mexico. 

With the identification data from Dr. Breitbart’s lab, fish population researchers can use the number of floating eggs, compare that with the rate of egg production and calculate the number of females releasing eggs for each species.

Dr. Peebles points out that this method is not only rapid, but could be very cost effective in comparison to conventional methods.

The most exciting aspect of this project for fisheries scientists is the discoveries that await them.  Dr. Peebles notes, “This method is one of the best, if not the best, methods of detecting spawning in marine fish.” 

And by identifying new spawning grounds, resource managers have the ability to increase protection of spawning habitats to ensure the longevity of ecologically and economically important species.

Oceanography Camp for Girls 2017

ST. PETERSBURG, FL - The Oceanography Camp for Girls, which held its 25th anniversary last year, has just graduated another class of aspiring scientists and environmentally conscious thinkers.  The three-week camp teaches girls about science by having them be the scientist.  Hands-on work in the field and laboratory, as well as a strong focus on careers, gives participants a holistic view of what it means to be a scientist and what a future STEM career might look like.  Under the leadership of Dr. Teresa Greely and Dr. Angela Lodge and the teaching and mentoring of the graduate students of the College of Marine Science (CMS), the girls learn the social and technical aspects of working in science. 

Faculty members and researchers of CMS and scientists from the community fulfilled additional teaching roles and provided the girls further career insight.  Field excursions included Fort Desoto, Shell Key, Caladesi Island, Clam Bayou, Sea World and a research cruise aboard the R/V Angari.  Laboratory rotations throughout CMS demonstrated concepts from microbiology, advanced microscopy, seawater analysis, satellite remote sensing, fish physiology, marine medical services, ROV techniques, beach profiling, and geological sedimentary analysis.  The scientists put an exclamation on their camp experience with presentations of their projects at a ceremony held in FWC-FWRI’s Karen A. Steidinger Auditorium.

Oxygen Minimum Zones expanding

ST. PETERSBURG, FL - Recent research suggests that oxygen levels are declining, and oxygen minimum zones expanding, throughout the world's oceans as a result of climate change. Members of the Seibel lab have just returned from a month-long cruise aboard the R/V Sikuliaq in the Eastern Tropical Pacific studying the low-oxygen tolerance of marine animals. Zooplankton in this region display the lowest critical oxygen levels (highest tolerance) of any animals ever measured and live on the edge of oxygen limitation.

PhD student Michelle Masi collaborates with NMFS

ST. PETERSBURG, FL - On Oct 17, 2016, Michelle Masi successfully defended her dissertation entitled, "An ecosystem-based approach to reef fish management in the Gulf of Mexico". In collaboration with the National Marine Fisheries Service, she used an ecosystem model to evaluate potential harvest control rules for use in Gulf of Mexico reef fish fisheries management. Her results suggested that using an adaptive management approach has the potential to improve fisheries yields while simultaneously increasing abundance and biodiversity of the reef fish assemblage. Joining as members of her academic committee were Dr. Michael Schirripa of NOAA's Southeast Fisheries Science Center in Miami, and Dr. Isaac Kaplan of the Northwest Fisheries Science Center in Seattle. Michelle Masi is a PhD Candidate in the Marine Resource Assessment program. She was recently hired to a full-time stock assessment position at the Fisheries and Wildlife Research Institute in St. Petersburg, FL. 

Philanthropist Anne Von Rosenstiel tours the laboratories of the USF College of Marine Science

ST. PETERSBURG, FL - Anne Von Rosenstiel maintains the same passion for the marine sciences that her late husband Werner Von Rosenstiel held.  Their philanthropic efforts have supported roughly 100 students up to the present and will continue into the future as her recent visit demonstrates. 

Anne and her daughter, Kathleen Davis, were joined by fellow guests, Drs. Susan and Peter Betzer.  A tour of selected labs from the Marine Science Laboratory and the Knight Oceanographic Research Center was guided by Howard Rutherford and presentations of the equipment, devices, and applications of the science were given by students Alex Ilich, Susan Snyder, Kelly Vasbinder, Jordon Meyer, and Erin Cuyler, and by faculty member Robert Byrne. 

The presenters expressed current and future relevance of their research to society, specifically through advanced fish population monitoring, analysis of toxic ingredients in sea life, modeling ocean parameters to improve Marine Protected Areas, satellite observations of ocean circulation and mixing which signal changes in climate, and the development of affordable devices that will allow citizen scientists to observe the effects of ocean acidification in our coastal waters.

Recent Antarctic expeditions uncover clues to Antarctic ice sheet evolution and climate sensitivity

ST. PETERSBURG, FL - Since she was an undergraduate, Dr. Amelia Shevenell has been interested in how ocean and atmospheric temperatures influence Antarctica’s ice sheets in the distant and not-so-distant past.

For at least 34 million years, Antarctica has been partially or completely covered in ice. Plate tectonics positioned Antarctica over the pole more than 65 million years ago, and drove India, Australia, and South America northward during the breakup of the supercontinent, Gondwana. This tectonic break-up formed the Southern Ocean, which encircles Antarctica. The Antarctic Circumpolar Current now mostly isolates Antarctica from heat derived from lower latitudes, but not completely. South of the Polar Front, warm nutrient-rich waters formed in northern latitudes upwell, bringing heat to Antarctica’s ice sheets. Both modern and geologic observations indicate to Dr. Shevenell that oceanic and atmospheric warming influences Antarctica’s ice sheet stability. 

NSF funded research aboard the US ice-breaker R/V Nathaniel B. Palmer in 2014 is yielding new information on the role of ocean and atmospheric temperatures on East Antarctica’s ice sheet evolution.

By studying the marine geologic record close to Antarctica’s ice sheets, researchers seek to understand the mechanisms by which glaciers retreat when climates were as warm or warmer than present. During the 2014 expedition to the Sabrina Coast, East Antarctica, Shevenell and her collaborators discovered that the East Antarctic Ice Sheet is more sensitive to climate changes than previously thought. This is important because global sea level would rise 53 meters (174 feet) if the East Antarctic Ice Sheet melted completely. More realistically, ice melt from the most sensitive regions of East Antarctica could raise global sea levels ~19 meters (~60 feet). Glaciers along the Sabrina Coast are presently retreating and could contribute 3–5 meters (9–16.5 feet) of global sea level rise in a warming world.

Shevenell, USF graduate students, and collaborators collected evidence that ice expanded to the Sabrina Coast in the early-to-middle Eocene, much earlier than is traditionally accepted. They discovered deep channels carved into sediments and evidence for least 11 glacial advances and retreats across the continental shelf. These results indicate variability of regional glaciers may have been enhanced by large amounts of meltwater during the Oligocene and Miocene, geologic times when climate was warmer and atmospheric CO2 higher than at present. About seven million years ago as global climates cooled, regional glaciers expanded, stabilized, and were not influenced by meltwater. These results indicate that the East Antarctic Ice Sheet has long responded to climate variability. If meltwater increases as with continued warming, Antarctica’s ice sheets might respond more dynamically than expected.

In early 2018, Dr. Shevenell will return to Antarctica aboard the International Ocean Discovery Program (IODP) drillship, the JOIDES Resolution. Dr. Shevenell and her USF CMS Ph.D. student, Imogen Browne, will work with an international team of scientists to drill sites in the Ross Sea, which will enhance understanding of Antarctica’s ice sheet evolution over the past 20 million years. This cruise is particularly exciting because Dr. Shevenell has worked for over a decade on proposing and planning this Expedition.    

As researchers explore Antarctica, more data is generated that can be plugged into ice and climate models to improve our collective understanding of ice sheet response to ongoing warming. Model improvements will ultimately enable scientists to make accurate estimates of regional sea level rise, which are critical to policy makers, particularly those in low-lying regions, such as Tampa Bay.
