The Nature Of Social Relationships In Bottlenose Dolphins (Tursiops Truncatus): Associations And The Role Of Affiliative, Agonistic, And Socio-Sexual Behaviors, Briana Nicole Harvey Aug 2015

The Nature Of Social Relationships In Bottlenose Dolphins (Tursiops Truncatus): Associations And The Role Of Affiliative, Agonistic, And Socio-Sexual Behaviors, Briana Nicole Harvey

Master's Theses

Little is known about the specific behavioral exchanges that occur on a day-to-day basis between dyads of bottlenose dolphins (Tursiops truncatus). This thesis assesses proximity between dyads (~ 2 meters) and the proportion of time that is spent in either an affiliative, agonistic, or socio-sexual context within age/sex pairings of dolphins in order to better understand the nature of social relationships in this species. Observations of bottlenose dolphins housed at the Roatan Institute of Marine Sciences, collected in 2010, provided 10.5 hours of underwater footage for assessment of association coefficients and proportions of interactions. These data suggested similar …


Bottlenose Dolphin (Tursiops Truncatus) Behaviors In The Presence Of Active And Non-Active Shrimp Trawlers In The Mississippi Sound, Crysta M. Lorenz May 2015

Bottlenose Dolphin (Tursiops Truncatus) Behaviors In The Presence Of Active And Non-Active Shrimp Trawlers In The Mississippi Sound, Crysta M. Lorenz

Honors Theses

Bottlenose dolphins, Tursiops truncatus, are reported to have close associations with shrimp trawlers worldwide. The goal of this study was to assess differences in the behavior for bottlenose dolphins between activity states of shrimp trawlers in the Mississippi Sound. During active trawling, nets are actively gathering the catch closely behind the trawler, which provide feeding opportunities for bottlenose dolphins. Non-active groups are not able to take advantage of feeding prospects and display fewer feeding behaviors and maintain a farther distance than active trawler groups. Video of trawlers were collected from the Mississippi Wild Dolphin Project and analyzed for feeding …
