Annotated Bibliographies
Listed below are all the sources I found during research and used in my essays and projects.
Sources for Literature Review of Dolphin Communication (HCP)
Arranz, P., et al. “Discrimination of Fast Click-Series Produced by Tagged Risso’s Dolphins (Grampus Griseus) for Echolocation or Communication.” Journal of Experimental Biology, vol. 219, no. 18, Sept. 2016, pp. 2898–2907.
Patricia Arranz is a Ph.D. student and researcher at the University of St. Andrews in Scotland. She is part of the Department of Animal Biology and focuses on studying the behavior of Risso's dolphins in the wild. The article explores the purpose of fast versus slow clicks of Grampus griseus and concludes that not adequate can be collected through DTAGS for burst pulsed clicks, suggesting further work be done.
Herzing, Denise L. “Clicks, Whistles and Pulses: Passive and Active Signal Use in Dolphin Communication.” Acta Astronautica, vol. 105, no. 2, Dec. 2014, pp. 534–537.
Denise Herzing is the Director of the Wild Dolphin Project. She has been researching on dolphin communication for more than 30 years. She earned her Ph. D. in Behavioral Biology at the Union Institute and the University of Vermont. Herzing reviews the difference between passive listening and active vocal production of dolphins and analyzes the drawbacks in measurement methods of dolphin communication at the time, suggesting improvements for future research.
Janik, Vincent, and Laela Sayigh. “Communication in Bottlenose Dolphins: 50 Years of Signature Whistle Research.” Journal of Comparative Physiology A: Neuroethology, Sensory, Neural & Behavioral Physiology, vol. 199, no. 6, June 2013, pp. 479–489.
Vincent Janik is the Director of the Scottish Oceans Institute and researcher and professor at University of St. Andrews in Scotland. He focuses on vocal communication and cognition complexity of bottlenose dolphins in the wild. Laela S. Sayigh is an assistant professor, focusing on animal behavior and cognitive science at Hampshire College. She received her Ph.D. from Massachusetts. Janik and Sayigh give background context on previous signature whistle research, define the signal whistle, analyzing the components of signal whistles, compare individual whistles to group whistles, and compare the dolphins sound to those of other mammals. Institute of Technology/Woods Hole Oceanographic Institution Joint Program and her B.A. from the University of Pennsylvania.
Janik, Vincent M., et al. “Signature Whistle Variations in a Bottlenosed Dolphin, Tursiops Truncatus.” Behavioral Ecology and Sociobiology, vol. 35, no. 4, 1994, pp. 243–248.
An older publication of marine researcher Vincent Janik analyzes the components of dolphin whistling. There are two types of information given: the specific dolphin producing the whistle and the context of the situation and environment the dolphin is in as it makes the whistle. This research is a foundation and precursor of Janik’s more recent publication on dolphin signature whistle, which comprises of 50 years worth of data and analysis.
Mooney, T Aran et al. “Sonar-induced temporary hearing loss in dolphins.” Biology letters vol. 5, 2009, pp. 565-7.
T. Aran Mooney, an associate scientist with tenure at Woods Hole Oceanographic Institute, focuses on the animal perception of the world through bioacoustics. His research on mammals ranges from bears to fish, but for this article, he focuses on dolphins. This article sheds light on temporary hearing loss in dolphins after prolonged, repeated exposures to sonar waves. He quantifies the intensity of the sonar sound using decibels that adversely damages dolphins’ ability to listen.
van Ginkel, Chantal, et al. "Whistling in a noisy ocean: bottlenose dolphins adjust whistle frequencies in response to real-time ambient noise levels." Bioacoustics 27.4, 2018, pp. 391-405.
Chantal van Ginkel, a current graduate student studying marine mammal acoustics and limnology at the University of Wisconsin-Madison, proves that dolphins are able to adapt to their environment by adjusting the frequencies of their whistles. It is a crucial skill to avoid the ambient noise in the open ocean to mask dolphin communication. Dolphins with high-frequency whistles are less likely to be masked in areas with high levels of noise.
