ABSTRACT WEST INDIAN MANATEE (TRICHECHUS MANATUS) HABITAT CHARACTERIZATION USING SIDE-SCAN SONAR by Mindy J. McLarty Chair: Daniel Gonzalez-Socoloske ABSTRACT OF GRADUATE STUDENT RESEARCH Thesis Andrews University School of Arts and Sciences Title: WEST INDIAN MANATEE (TRICHECHUS MANATUS) HABITAT CHARACTERIZATION USING SIDE-SCAN SONAR Name of researcher: Mindy J. McLarty Name and degree of faculty chair: Daniel Gonzalez-Socoloske, Ph.D. Date completed: April 2017 In this study, the reliability of low cost side-scan sonar to accurately identify soft substrates such as grass and mud was tested. Benthic substrates can be hard to classify from the surface, necessitating an alternative survey approach. A total area of 11.5 km2 was surveyed with the sonar in a large, brackish mangrove lagoon system. Individual points were ground-truthed for comparison with the sonar recordings to provide a measure of accuracy. -
Functional Morphology of the Vertebral Column in Remingtonocetus (Mammalia, Cetacea) and the Evolution of Aquatic Locomotion in Early Archaeocetes
Functional Morphology of the Vertebral Column in Remingtonocetus (Mammalia, Cetacea) and the Evolution of Aquatic Locomotion in Early Archaeocetes by Ryan Matthew Bebej A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Ecology and Evolutionary Biology) in The University of Michigan 2011 Doctoral Committee: Professor Philip D. Gingerich, Co-Chair Professor Philip Myers, Co-Chair Professor Daniel C. Fisher Professor Paul W. Webb © Ryan Matthew Bebej 2011 To my wonderful wife Melissa, for her infinite love and support ii Acknowledgments First, I would like to thank each of my committee members. I will be forever grateful to my primary mentor, Philip D. Gingerich, for providing me the opportunity of a lifetime, studying the very organisms that sparked my interest in evolution and paleontology in the first place. His encouragement, patience, instruction, and advice have been instrumental in my development as a scholar, and his dedication to his craft has instilled in me the importance of doing careful and solid research. I am extremely grateful to Philip Myers, who graciously consented to be my co-advisor and co-chair early in my career and guided me through some of the most stressful aspects of life as a Ph.D. student (e.g., preliminary examinations). I also thank Paul W. Webb, for his novel thoughts about living in and moving through water, and Daniel C. Fisher, for his insights into functional morphology, 3D modeling, and mammalian paleobiology. My research was almost entirely predicated on cetacean fossils collected through a collaboration of the University of Michigan and the Geological Survey of Pakistan before my arrival in Ann Arbor. -

Recommendations for the care and maintenance of marine mammals © Canadian Council on Animal Care, 2014 ISBN: 978-0-919087-57-6 Canadian Council on Animal Care 190 O’Connor St., Suite 800 Ottawa ON K2P 2R3 http://www.ccac.ca Acknowledgements The development of the Recommendations for the care and maintenance of marine mammals was com- missioned to the Canadian Council on Animal Care (CCAC) by the Department of Fisheries and Oceans Canada (DFO). To complete this task, the CCAC Standards Committee created the ad hoc subcommittee on marine mammals. We acknowledge and thank all the members of the subcommittee who worked together to develop, review, and guide this document through to publication: Dr. Pierre-Yves Daoust, University of Prince Edward Island Mr. John Ford, Fisheries and Oceans Canada (DFO) Mr. Henrik Kreiberg, Fisheries and Oceans Canada (DFO) Dr. Clément Lanthier, Calgary Zoo Dr. Kay Mehren, Veterinarian Emeritus, Toronto Zoo Ms. Tracy Stewart, Marineland of Canada Mr. Clint Wright, Vancouver Aquarium Dr. Gilly Griffin, Canadian Council on Animal Care We would also like to take this opportunity to recognize the dedication and vision of Dr. Jon Lien (Memo- rial University, deceased 2010), the Committee’s first Chair. Jon played a pivotal role in the creation of this document. It was the Lien Report: A review of live- capture and captivity of marine mammals in Canada that inspired DFO to request that CCAC develop recommendations for the care and maintenance of marine mammals. His vision became a collective goal - to improve the quality of life for all marine mammals held in captivity. -
Anatomical Adaptations of Aquatic Mammals
THE ANATOMICAL RECORD 290:507–513 (2007) Anatomical Adaptations of Aquatic Mammals JOY S. REIDENBERG* Center for Anatomy and Functional Morphology, Department of Medical Education, Mount Sinai School of Medicine, New York, New York ABSTRACT This special issue of the Anatomical Record explores many of the an- atomical adaptations exhibited by aquatic mammals that enable life in the water. Anatomical observations on a range of fossil and living marine and freshwater mammals are presented, including sirenians (manatees and dugongs), cetaceans (both baleen whales and toothed whales, includ- ing dolphins and porpoises), pinnipeds (seals, sea lions, and walruses), the sea otter, and the pygmy hippopotamus. A range of anatomical sys- tems are covered in this issue, including the external form (integument, tail shape), nervous system (eye, ear, brain), musculoskeletal systems (cranium, mandible, hyoid, vertebral column, flipper/forelimb), digestive tract (teeth/tusks/baleen, tongue, stomach), and respiratory tract (larynx). Emphasis is placed on exploring anatomical function in the context of aquatic life. The following topics are addressed: evolution, sound produc- tion, sound reception, feeding, locomotion, buoyancy control, thermoregu- lation, cognition, and behavior. A variety of approaches and techniques are used to examine and characterize these adaptations, ranging from dissection, to histology, to electron microscopy, to two-dimensional (2D) and 3D computerized tomography, to experimental field tests of function. The articles in this issue are a blend of literature review and new, hy- pothesis-driven anatomical research, which highlight the special nature of anatomical form and function in aquatic mammals that enables their exquisite adaptation for life in such a challenging environment.

USA Terrestrial Mammals Email: The voice box, or larynx, is the organ of vocalization used by most terrestrial mam- [email protected] mals. It initially evolved from the protective anatomy used to keep water out of a buoyancy organ in fish (the swim bladder). The main function of the larynx remains protection, only now it prevents incursions of foreign material into the “windpipe” (trachea) and lungs of mammals. The entrance of the larynx is sealed by a pair of vocal “cords” (vocal folds). In ad- dition, there are tall cartilages (epiglottic and corniculate) that act as splashguards to deflect food and water away from the opening. These cartilages overlap in front with the soft palate and behind with the posterior wall of the airspace (pharyn- geal wall) to interlock the larynx with the rear of the nasal cavity (Figure 1). -

As the keynote speaker Tom O’Shea noted, “It has been a long 15 years since our first meeting and an abundance of new information on Sirenian natural history, anatomy, physiology, genetics, medicine and conservation is now available”. The idea for the conference was initiated by Dr. Greg Bossart and deftly organized by fellow colleagues from Harbor Branch Oceanographic Institute at Florida Atlantic University, Dr. Juli Goldstein and Stephen McCulloch. Together, they worked to acquire the necessary funding and target a select group of esteemed speakers (above) from around the world to make presentations at the renowned Georgia Aquarium.
