As part of the HHMI Science Educations Alliance Phage Hunters Program, twenty-six College of Charleston undergraduate student were published November 27, 2013 in the recent Genome Announcement. This publication includes two published NCBI Genome Accession Numbers. Hyperlinks to genome accession numbers are within attached paper (Genome Announc.-2013-Hatfull-). Many of these students worked with Dr. Ana Zimmerman here at the Grice Marine Laboratory. Dr. Erin Morris-Richard and Dr. Chris Korey from the downtown campus also worked on this project. The project website lists details of the phages found. With phage names like DirtMcgirt (pictured) and FuzzyWuzzy you should take a look at the wonderful research these students are doing.
On September 28th, Fort Johnson had another successful beach sweep thanks to George Reikerk, the Beach Sweep Coordinator. Participants included Grice graduate students, students from James Island Charter and Porter-Gaud high schools, as well as DNR and MUSC staff. The area covered included Fort Johnson, Grice Beach, and the south end of Morris Island. All total of 2.3 miles of coastline and 3 boat loads of trash were collected. The trash included 34 bags of trash and usual collection of floats, lumber, boat parts and rope. the This year, Hope Wertz, a Marine Biology graduate student, will be comparing the plastic materials collected with microplastic particles that can be found in our estuarine waters and sediments. You can review a list of what was found: Beach Sweep 2013 summary
Visiting scientist, Dr. Darwin Jorgensen (from Roanoke College in Virginia), and two of his undergraduate students, Vicki Brings and Micah Spruill, have been looking at the physiological support of underwater walking in lobsters and blue crabs. This lobster, walking at a speed of about 2 km/hr, is instrumented to measure hemolymph (blood) pressure in the circulatory system and hydrostatic pressure in the two gill chambers (located on either side of the thorax). The acrylic mask mounted at the head end of the animal collects the seawater exiting the two gill chambers. The yellow piece in the mask is an electromagnetic flow probe and is used to measure the amount of seawater being pumped through the gill chambers per minute. This work is designed to help us understand how the gills work in concert with the cardiovascular system to support migratory activity in these commercially-important crustaceans. Learn more about the lobster on a treadmill below.
Grice Marine Laboratory’s REU students are sparking the Charleston community’s interests in marine science with their ongoing summer research. One REU student, Claire Hancock, is acknowledged for her work with coral bleaching. This bleaching technique in coral occurs from various stresses in the marine environment and is fatal to coral. For more information, visit the recent article printed in Charleston’s Post and Courier on July 26, 2009.
Jeremy Goldbogen, a Summer 2001 Intern in the Fort Johnson REU Program, has made some stunning discoveries regarding the mechanics of foraging behavior in rorqual whales. Jeremy related the story of his research exploits to the 2009 Fort Johnson REU Interns as part of the new Summer Program lecture series Fort Johnson REUs Reporting Home. Jeremy’s findings form the basis for his soon-to-be defended PhD dissertation at the the University of British Columbia in Vancouver, BC. His work has received extensive coverage in the popular press, such as the New York Times. Listen to the CBC radio podcast.
In a newly published article in the journal Biological Bulletin, Hannah Giddens (a former CofC undergraduate) found that elevated seawater temperatures can cause herbivore to alter their feeding preferences, in some cases toward consuming foods that are of poorer quality even when higher quality foods are available. This is the first demonstration of temperature-dependent shifts in feeding preference, and provides another example of how global increases in seawater temperature may alter the dynamics of nearshore ecosytems in surprising ways.
