Greetings MARMAM!

Join us on *Thursday, 16 December 2021 at 4 PM EST (1 PM PST / 9 PM UTC)* for
the next SMM Seminar Editors' Select Series: Friends Through Thick and
Thin: How Injuries Disrupt Bottlenose Dolphin Associations with Michelle
Greenfield of the Cornell University College of Veterinary Medicine.
Free to attend. Registration required. Presented online on Zoom.
Register here:

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' SelectSeries 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:*
Social connectivity is important for measuring the fitness of common
bottlenose dolphins because social relationships can enhance survival,
reproduction and foraging success.  Human-related injuries such as boat
strikes or fishing gear entanglements can potentially remove an individual
from its association network and disrupt these relationships. Using data
from the long-term resident dolphin community in Sarasota Bay, Florida, we
investigated how these injuries affect the dolphins' social associations by
examining the differences in their social networks before and after injury.
We found that while injured dolphins were found in groups of similar size
to those prior to their injury, their number of preferential associations
(i.e., their best friends) seemed to decline immediately after injury but
were often regained within two years following injury. An individual’s
strongest associations, namely those between mothers and calves and those
between male alliance partners, remained stable before and after injury.
Because dolphins rely on these relationships for survival, increased
occurrence of injury from boating and fishing may put the animals at
greater risk for long-term survival, including making them more vulnerable
to predation.

*About the presenter:*
Michelle Greenfield is a veterinary student at the Cornell University
College of Veterinary Medicine (2023). She holds a Bachelor of Arts degree
in ecology and evolutionary biology from Princeton University where she
began her research with the Chicago Zoological Society’s Sarasota Dolphin
Research Program. Since then, Michelle has continued her studies of marine
mammals working with organizations such as Hubbs SeaWorld Research
Institute and the United States Navy's Marine Mammal Program. Her research
interests focus on bottlenose dolphin social behavior and regenerative
medicine in marine mammals. In addition to her research and clinical work,
Michelle is the producer and host of Aquadocs Podcast, a top 50 life
sciences podcast and the leading podcast on aquatic veterinary medicine (
