Lecture: How do we go about understanding populations?

What do we want to know about populations of animals? How do we go about doing this? What are some models we might use? And how many fish are in my lake?

Here I introduce the topic of mark-recapture models and discuss closed population models. In future lectures I will talk about open population models.

The file is too large to post directly to this website so I have uploaded it to Youtube. You can see the video here: link.
