Predation Part 3: Exploitation & Population Cycles

This is the third part of a three-part presentation on predation, designed for use in an undergraduate introductory ecology course. All three parts can be found on my YouTube channel:

Part 1: How to Eat Another Organism
Part 2: How to Avoid Being Eaten
Part 3: Exploitation & Population Cycles

I am so glad I found this video! I have an exam tomorrow and I was really confused and you made this unit easier to understand.

Thank you sooo much for this! You explained this so well! I just wish you could have gone over the more complex models as well.

Hi, great video, thanks so much! I just wanted to check - at 13:33, is the bottom right hand box meant to have the blue arrow and the green arrow swapped?

Thank you for uploading this video. There is still one thing that I keep thinking about, which is one of the weak points of the Lotka-Volterra equitations. You said (and I thought like that as well first) that the model assumes that prey only dies by predation, but aren't environmental influences and diseases included in r? I thought r represents birth rate - death rate. But this is a constant value and perhaps that is the weak point? (Apologies for my English). Could you please explain this to me?

What is the conversion efficiency? How do you calculate it?
