    e.g. Marine Mammal Science

  • SIO 133 – Goals of the Course

     Understand marine mammal diversity, evolution, physiology, ecology, and behavior

     Challenges for mammals living in the sea  Thermal regulation  Diving hydrostatics  Communication  Social systems, reproduction

     Conservation and management  Whaling  Fisheries interactions

  • Zooplankton Biomass

  • Benthic Biomass

  • • Plankton (float, limited ability to propel themselves)

    • phytoplankton (plants)

    • zooplankton (animals)

    • Nekton (swimmers): fish, reptiles, mammals, birds ...

    • Benthos: live on the bottom (epifauna) or within the sediments (infauna)

    • Many change: plankton early in life  benthic or nekton

    Lifestyles of Marine Organisms

  • Marine Food Web Availability of food established by:

    - Primary production and number of trophic levels
