Resistance Surface Modeling - Dr. Bill Peterman

Lecture Synopsis

This lecture will focus on the concept of landscape resistance. In particular, it will introduce you to:

1. How landscape features may impose 'resistance' to organism movement and/or gene flow.
2. How we can represent the landscape as a resistance surface.
3. Categories of resistance models, focusing on least cost paths and circuit analysis.
4. The effects of changing resistance values, and approaches for selecting those values.
