Manatee Reproduction

Jonathan is a post-doc in the Aquatic Animal Health Program whose research focuses on studying the reproductive physiology of male Florida manatees. His research encompasses multiple aspects including reproductive histology, basic semen analysis, and structural sperm analysis, all of which helps further our understanding of the biology of the Florida manatee. He has been able to accomplish some aspects of his research using a state of the art computer aided sperm analysis system, which was afforded through a generous funding award received from the College of Veterinary Medicine. Jonathan’s research accomplishments include the Reep-Bonde Prize for his research on manatee biology as well as the Excellence in Doctoral Research Award from the College of Veterinary Medicine.
