Resistance Modeling

One of the most blantant phenotypes associated with Landscape Genetic approaches is the use of resistance surfaces. Resistance modeling is based upon the fundamnetal notion that landscapes contain heterogeneous collections of habitat types and those types may have differential permeabiltiy to the movement of organisms. The difficult part here is that we are entirely ignorant of (1) which features the organisms are responding to on the landscape, (2) how much each feature influences the relative ability of the organism to move/disperse, and (3) what the proper granularity of the landscape feature is that the organism both recognizes and responds to.

Lecture Content

For this topic, I will be spending a bit of time covering the foundations of this topic as well as giving some concrete examples. To do so, you have access to the following slide set1.

Here is a recording of the Resistance talk I gave on Zoom.

Supplemental Materials

In addition to this lecture content, you may find the following information helpful as you go though these exercises.


Here is the activity associated with this particular topic.

Here is some code that I used to solve the questions in the activity.
