Presentation Transcript

  1. Marine Mammals • Diving • Adaptations for long and deep dives • High hematocrit • Muscles rich in myoglobin • Reduction of heart rate • Flexible rib cage • Majority of oxygen in blood and tissues

  2. Marine Mammals • Echolocation • Common in dolphins, porpoises, toothed whales • May occur in some baleen whales and pinnipeds Dolphins Whales Whales

  3. Marine Mammals • Migration • Baleen whales, pinnipeds • Toothed whales tend not to migrate

  4. Marine Mammals • Behavior • Playful behavior • Breeching • Spy hopping

  5. Ecology

  6. Ecology • Population Dynamics • Under favorable conditions populations can grow rapidly

  7. Ecology • Population Dynamics

  8. Ecology • Population Dynamics

  9. Ecology • Population Dynamics • Populations tend to be self-regulating • Populations grow until they reach carrying capacity • Population growth and carrying capacity may be determined by limiting resource • Limiting resources are different for different populations

  10. Ecology • Species Interactions • Intraspecific competition • Ex – Competition for algae by sea urchins • Ex – Competition for shells by hermit crabs • Interspecies competition
