Understanding Sea Otter Populations: Estimation and Observations in Glacier Bay

Discover the fascinating world of sea otters in Glacier Bay, Alaska. This guide explores the differences between populations and communities, highlighting the importance of understanding sea otter populations. Using the capture-tag-recapture method, scientists can estimate the size of these adorable marine mammals. Join us on a field trip to learn how we can monitor and appreciate the interconnectedness of organisms in our ecosystem. Uncover the importance of population studies and contribute to wildlife conservation efforts.

  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!
