  1. Population Estimation

  2. Population • A group of organisms of the same species living in the same area at the same time

  3. How does a population differ from a community? • A population refers to one group of organisms in a particular area • A community refers to all the populations of organisms in a particular area

  4. Sea Otter Observations • They are cute! • They are FUN! • They are cuddly! …..eh….not really. What are your ‘real’ observations?

  5. Why is it important for us to know the populations of the organisms among us? • Remember, we are all connected in the great circle of life 

  6. Let’s take a field trip to Glacier Bay, Alaska

  7. How do I determine the size of the sea otter population? • SCIENTISTS: Use the capture-tag-recapture method • By capturing otters, tagging them, and placing them back in the wild we can estimate their population size. • Complete your procedure to discover how many sea otters live in Glacier Bay!
