Dr. Stephen Kajiura, Professor Biological Sciences at Florida Atlantic University, studies and will discuss how Blacktip sharks aggregate by the thousands in nearshore waters of southeast Florida every winter. For the past decade we have employed aerial surveys with airplanes and drones, acoustic and satellite telemetry, underwater video monitoring, and animal-borne data loggers to examine the distribution and movements of sharks as they overwinter along our coast and migrate up the eastern seaboard. We have found that these sharks have shifted their distribution to higher latitudes in response to warming oceans. In the future, southeast Florida might actually be deprived of these seasonally important predators which could have cascading effects through multiple trophic levels.
