Maternal and alloparental discipline in Atlantic spotted dolphins (Stenella frontalis) in the Bahamas
Title
Maternal and alloparental discipline in Atlantic spotted dolphins (Stenella frontalis) in the Bahamas.
Creator
Weinpress, Meghan., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description
Discipline was implemented by mothers and alloparent spotted dolphins (Stenella frontalis) mothers and alloparents on Little Bahama Bank, Bahamas. Disciplinarians were significantly more likely to be adults than juveniles. Although most disciplinarians were female, males were also observed to perform discipline. The recipients of discipline were male and female, and significantly more likely to be calves than juveniles. Pursuit, contact, and display behaviors were used in discipline, however...
Show moreDiscipline was implemented by mothers and alloparent spotted dolphins (Stenella frontalis) mothers and alloparents on Little Bahama Bank, Bahamas. Disciplinarians were significantly more likely to be adults than juveniles. Although most disciplinarians were female, males were also observed to perform discipline. The recipients of discipline were male and female, and significantly more likely to be calves than juveniles. Pursuit, contact, and display behaviors were used in discipline, however pursuit behaviors were most often observed. Variables such as age class, sex, and parity were not found to influence how discipline was implemented. The durations of all disciplinary pursuits were under thirty seconds, and successful pursuits had slightly shorter duration than unsuccessful pursuits. Disciplinarian success was not significantly influenced by age class, sex, parity, or behavior used.

Does size really matter
Title
Does size really matter: how synchrony and size affect the dynamic of aggression between two sympatric species of dolphin in the Bahamas.
Creator
Cuksick, Jessica A., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description
Bottlenose (Tursiops truncatus) and spotted (Stenella frontalis) dolphins are sympatric species, resident to Little Bahama Bank, Bahamas. A unique, dynamic methodology quantified how interspecific aggression changed over time in terms of the individuals participating, context, and behaviors used. The timing of human observation relative to the onset of aggression did not result in differences in the proportion of behaviors observed. Highly intense behaviors were used most often. The...
Show moreBottlenose (Tursiops truncatus) and spotted (Stenella frontalis) dolphins are sympatric species, resident to Little Bahama Bank, Bahamas. A unique, dynamic methodology quantified how interspecific aggression changed over time in terms of the individuals participating, context, and behaviors used. The timing of human observation relative to the onset of aggression did not result in differences in the proportion of behaviors observed. Highly intense behaviors were used most often. The synchronous state of spotted dolphin groups, not the presence alone, was a crucial factor in determining the onset and progression of aggression. When synchronous, spotted dolphins successfully dominated the larger bottlenose dolphins. Two levels of dominance were observed. Within a single encounter ("encounter level"), one species did dominate the other. When all aggressive encounters were considered collectively over the long term ("gross level"), one species did not dominate the other. The combination of contextual factors best determined the dynamic of interspecific aggression.

Aggressive Behaviors Of Adult Male Atlantic Spotted Dolphins (Stenella frontalis) During Intraspecific And Interspecific Aggressive Interactions

Show moreAtlantic spotted dolphins (Stenella frontalis) and bottlenose dolphins (Tursiops truncatus) are two sympatric species resident to the Bahamas. The visibility of the Bahamian water provided a unique opportunity to study spotted dolphin communication during aggression. This study’s main focus was to decipher any similarities or differences in the behaviors used by spotted dolphins during interspecific and intraspecific aggression. Both similarities and differences were discovered. Biting, following, and chasing behavioral events were used more during interspecific aggression, while the display behavioral class was used more than the contact behavioral class during intrabut not interspecific aggression. This study showed that spotted dolphins use more energy intensive and risky behaviors when fighting interspecifically. This could result from having to fight and defend females from a larger species, trying to avoid sexual harassment from bottlenose males, or needing to use behaviors that are more overt and easily understood during interspecies communication.
