COURSE CONTENT

Outcomes and Objectives:
At the conclusion of this course, the student should be able to:

Upon successful completion of this course, the student will be able to:

1. Describe the features of the class mammalia and compare and contrast the characteristics of the orders and families of marine mammals.

2. Summarize key physical features of the marine environment including light, temperature, pressure, and nutrient distribution.

3. Compare and contrast primary and secondary production levels in major areas of the ocean and explain how these impact the distribution, population size, and migration patterns of marine mammals.

4. Explain systematics and cladistics, and apply these concepts to marine mammals.

5. Synthesize the concepts of evolutionary mechanisms, adaptation, and  speciation, and apply these concepts to marine mammal evolution.

6. Explain mammalian homeostasis and energetics and the anatomical, physiological, and behavioral adaptations made by marine mammals for life in the sea.

7. Compare and contrast capabilities and functions of the sensory systems (sight, smell, touch, taste, and sound), for different marine mammal  groups and their use in communication, social organization, orientation, and feeding.

8. Compare and contrast the various feeding mechanisms of marine mammals and analyze how these differences impact, and are impacted by, the social structure and physiological and morphological adaptations of marine mammals.

9. Compare and contrast the mating and social systems of marine mammals and analyze the role of habitat and evolution in shaping these systems.

10. Summarize past and present threats to marine mammal populations including hunting, pollution, habitat and prey loss and describe and analyze the effectiveness of current national and international laws regulating marine mammal populations.

11. Recognize and describe the marine mammal species found along the California coast and describe their ecology, natural history, and world population status.
