Graduate education

Molluscan Ecology graduate students are enrolled in the College of William and Mary's School of Marine Science graduate program and are part of the VIMS Department of Fisheries Science. Both Master's and Ph.D. students complete research projects that lead to Master of Science theses or Doctoral dissertations. These students are an integral part of the Molluscan Ecology program.

Student Research 

Alexis HollanderResearch experience is available to graduate, undergraduate and high school students working in the Molluscan Ecology Lab. Read more about current graduate student research.

Training Opportunities Provided by the VIMS Molluscan Ecology Lab: Graduate Students

Since 2015, five University of Southern Mississippi graduate students have been trained in shell aging techniques. Kelsey Kuykendall, Sara Pace, Leanne Poussard, Kathleen Hemeon, and Jill Sowers received individualized tutorials ranging from weeks to months from the VIMS Molluscan Ecology Lab. They learned cutting, grinding, polishing, and aging techniques for various mollusc shells, thus contributing data to their graduate studies and furthering progress related to shellfish projects funded by the Science Center for Marine Fisheries (SCEMFIS)

M. Chase Long learned shell aging techniques for his Master’s work and presented his research at the 2019 National Shellfish Association Meeting in New Orleans. Chase was awarded a 2019 John A. Knauss Marine Policy Fellowship and traveled to Washington, D.C. to begin his Fellowship on February 1st, 2019.

Kathleen Hemeon, USM, also co-authored a laboratory techniques manual which aids in the education of future students and technicians.

Non-Graduate Training and Community Outreach

With regard to training outside of the graduate program, Sara Thomas and Erin Mohr, technicians with the VIMS Sea Scallop Program, as well as Brittany Baker, Oakland University, were provided training by Dr. Roger Mann, Melissa Southworth, and Theresa Redmond in aging scallops.  Sara Thomas learned to age scallops via shell isotope analysis and, in turn, contributed to instructional and field videos produced by the VIMS Molluscan Ecology Lab.

Lab & Research Technician, Theresa Redmond, taught a shell aging class to a group at Haskin Shellfish Research Laboratory, Rutgers University as well as a workshop at VIMS. Marine Scientist Senior, Melissa Southworth, furnished presentations followed by a hands-on demonstration of numerous mollusc specimens to several 5th grade science classes at Bethel Elementary School on “Bivalve Day.” (See below and the Flickr photo gallery)

Chesapeake Bay Governor’s School high school student, Emma McKee, as well as William & Mary undergraduate, Khalil Russell, were taught shell aging techniques. Khalil presented a poster, "Can we Discern Major Meterological and Environmental Events in the Growth Record of the Long Lived Clam Arctica islandica" at the 2019 National Shellfisheries Association Meeting in New Orleans. Emma used the techniques and knowledge she learned regarding the growth cycles of ocean quahog, Arctica islandica, for her senior research project. She also won a 2019 Chesapeake Bay Governor's School Science Symposium Outstanding Presentation Ribbon as well as second place in the Virginia Junior Academy of Science Overall Presentations for the Commonwealth of Virginia. Emma began her freshman year at William & Mary in the fall of 2019.

Students at Bethel Elementary School in Gloucester get a lesson on bivalve biology along with their commercial and ecological importance from Missy Southworth, VIMS Molluscan Ecology, April 2019.  The Molluscan Ecology Lab has several ongoing aging projects for oysters, clams and scallops. 

Students were able to see the process of how clams are aged using microscopic internal growth rings laid down within the shell structure and got to try their hand at aging scallop shells using external growth lines.

Formal Graduate Molluscan Ecology Courses

Larval Ecology (MS658) - examines the Ecology of marine larval forms: spawning and development patterns; physical limitations on the fertilization process, feeding, nutrition, and mobility; size and parental investment, dispersal and metamorphosis, post-metamorphic survival.  (3 credits)

Malacology (MS668) - examines the evolution of the molluscs from the Cambrian to the present, radiation to the current 80,000 or so species, and the functional morphology and ecology of each of the major taxonomic groups. The section on cephalopods is taught by Dr. Michael Vecchione of the USNM, Smithsonian. The course concludes with a field trip to the research collection at the Smithsonian Institution in Washington DC. (3 credits)
