Untitled document
Upon 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
   within the class.
2.  Summarize the key features of the marine environment and assess how
   these features impact marine mammals and their predators and prey,
   including concepts of population ecology and biogeography.
3.  Compare and contrast primary and secondary production levels in major
   areas of the ocean and explain how this impacts the distribution,
   population size, and migration patterns of marine mammals.
4.  Demonstrate an understanding of classification and systematics and
   apply these concepts to marine mammals.
5.  Synthesize the concepts of mechanisms of evolution, 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 upon, 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 the different
   types 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.
