Grubbs Laboratory

Listen to this podcast for the latest publicity on Dr. Dean Grubbs' and Dr. Chip Cotton's paper disputing claims that the population of cownsoe rays in the Chesapeake bay had exploded. "It's biologically impossible for cownose ray populations to explode," says Dr. Grubbs. Cownose rays only have one pup every year, making it difficult for their population to "explode" as the 2007 study had claimed. Because of the slow rate of reproduction, the efforts to fish for these rays could be especially harmful.

More coverage on Dr. Dean Grubbs' and Dr. Chip Cotton's research on trophic cascades involving sharks, cownose rays, and bivalves. This article in Science highlights how unregulated pressure of rays could have detrimental effects on their populations.

Dr. Dean Grubbs' and Dr. Chip Cotton’s (FSUCML faculty members) latest research challenges a 2007 study claiming that shark declines led to rising populations of cownose rays, which were responsible for the collapse of oyster and shellfish industries along the Atlantic coast.

Dr. Dean Grubbs joins Lars Schmidt from the podcast, 21st Century HR, to discuss his career journey, how he became passionate about shark research, the dual role of an academic and researcher and more.

Dr. Chip Cotton and Dr. Dean Grubbs co-author a piece in Save Our Seas Magazine, which highlights the sharks that make up 53% of all living shark species - the ones that spend their entire lives more than 200 meters beneath the surface of the sea.

The FSUCML GulfSPAN survey, part of a larger NOAA survey, is conducted by FSUCML graduate students and volunteers. The surveyors search for sharks at sites in the Florida Big Bend and provide vital data about shark populations and habiat.

See a recap of the 2015 visitors to the FSUCML. We had folks from all over the world, including Brazil, Guam, Malaysia, and Indonesia. From research trips to field trips, we had a lot of excitement in 2015.

Dr. Dean Grubbs (FSUCML faculty) recently attended a meeting at the National Aquarium in Baltimore, Maryland to discuss the current state of the cownose ray population. This news clip shows Dr. Grubbs describing some of the issues this species faces.

Bowhunting poses a threat to cownose ray populations. Dr. Dean Grubbs (FSUCML faculty) comments on the market for cownose rays and the threats they face.

Dr. Dean Grubbs, FSUCML faculty, discusses his career as a marine biologist on the podcast, “Best Part of My Job” hosted by Lars Schmidt. Learn more about Dr. Grubbs’ early research and his methods for handling and sampling various shark species.
