Greetings MARMAM!

Join us on *Thursday, October 20th at 1 PM EDT (10 AM PDT / 5 PM GMT)* for
the next SMM Seminar Editors' Select Series: Behavior related vocalizations
of the Florida manatee (*Trichechus manatus latirostris*) with Dr. Beth
Brady of the Florida Atlantic University and Mote Marine Laboratory.

Free to attend. Registration required.

Presented online on Zoom.

Space on Zoom is limited to the first 500 attendees. The talk will also be
streamed live on the SMM Facebook page.

*The SMM Seminar Editors' Select Series highlights the latest and most
exciting marine mammal science published in the Marine Mammal Science
Journal. This is your chance to engage with marine mammal scientists, learn
and ask questions from anywhere in the world. All are welcome.*

*About this talk:*
Florida manatees produce a variety of vocalizations, but their function is
unclear. The goal of this study was to investigate if manatee vocalizations
could be correlated with behavior. Multiple underwater microphones were
used to record manatee vocalizations in four different environments and
behaviors. Vocalizations recorded from resting, playing, stressed and
feeding wild animals were statistically tested to determine whether
vocalizations produced varied with behavior and calf presence. We also
measured the length, amount of noise, and changes in pitch (frequency
modulation) from vocalizations to investigate if they differed between
behaviors. Results suggest manatees vocalize using few call types and vary
the structure of the call based on behavior. One call type was correlated
with calf presence. Noisier calls were more frequently observed during
play. The most common call manatees produced are called squeaks. Squeaks
were longer in length and higher in frequency modulation when animals were
stressed. This research provides a foundation for comparative studies on
vocal behavior for the Florida manatee as well as studies on related
species.


*About the presenter:*Beth was born and raised in rural Pennsylvania and
first found her interest in marine life on a family vacation. Although she
initially went to school to be a registered nurse, after a few years of
nursing, she realized her true passion was marine biology.
She returned to school and got her undergraduate degree at Kutztown
University, Pennsylvania. After graduation, she volunteered with multiple
marine mammal and wildlife organizations and found her love of manatees
through an extended internship at Florida Fish and Wildlife (FWC). After
the internship, she completed her Master’s at Nova Southeastern University
where she first became involved in studying underwater sound (acoustics)
and manatee vocalizations. She completed her doctorate at Florida Atlantic
University in 2020. She is currently a post doctoral research fellow at
Mote Marine Laboratory in Sarasota, FL.
Dr. Brady’s primary research investigates vocal communication in manatee
species. In addition, she is studying manatee behavior, ecotourism impacts,
and recently started flying drones to assess the body condition of Florida
manatees.

All the best,
