Predation
Online Lectures
Predation Part 1 - introduction, dingo/kangaroo and lake trout/sea lamprey case studies (note reading is CH 14 not CH 12 as stated at start of lecture)
Predation Part 2 - additive and compensatory mortality due to predation (note reading is CH 14 not CH 12 as stated at start of lecture)
Predation Part 3 - fixed effort and fixed quota human harvests (note reading is CH 14 not CH 12 as stated at start of lecture)
Predation Part 4A- the Lotka - Volterra model of predation
Predation Part 4B - evaluating the prediction of predator-prey cycles in the lab and in the wild
Predation Part 5- functional and numeric responses of predators to changes in prey density
Case Study
Predation Part 6- Risk effects in wolves and elk - how might the costs of AVOIDING predation affect prey dynamics?

Overheads
Populus Computer Lab
- POPULUS EXERCISE: PREDATION Covers the basic Lotka Volterra predator - prey model, and the effects on its predictions of adding: (1) density dependent prey population growth, (2) functional response by predators. Note that there is a key to the questions asked in the exercise (at the end). Try to answer a question before looking at the key.
- Start populus. At the main menu, select "Multi-Species Dynamics", then "Continuous Predator - Prey Models".
- Do NOT accidentally go to the Lotka - Volterra COMPETITION model, and do NOT accidentally go to DISCRETE Predator - Prey models.
