Ecological modeling

This module will focus on ecological modeling. We’ll start by discussing how and why models can be used (and misused) in ecology. Over the first 1-2 weeks, we’ll work through some simple mathematical models and gradually build complexity. Activities will focus on demystifying models and their underlying assumptions, sketching graphs, and performing simple analyses using algebra.

Then in weeks 2-3, students will construct models to address their own research questions, culminating in short group presentations.

We will be using breakout rooms frequently. Since you won’t be able to see my screen during a breakout session, I have compiled all of the activity prompts in a separate file here. Please also take the pre-test survey that has been posted to eLC (< 5 min).

By the end up this module, students should be able to:

1. Understand how & why simple models can be useful in ecology.

2. Draw insights from simple models with algebra and sketching of graphs.

3. Confidently read articles in ecology journals that include mathematical models.

4. Create a conceptual model that formalizes a ‘fuzzy’ research question and translates it into precise equations.

5. Understand enough about modeling to feel confident seeking additional help or collaboration.

Why model?

For today: please read Kokko et al. & Jackson et al.; take the survey on eLC

For next time: finish prompt 1.2 if we didn’t in class

Thursday Sep 17

From woolly hypothesis to precise equation

For next time, read Courchamp et al. & Strauss et al. 4 sentences each:

1. What was the motivating ‘woolly’ hypothesis?

2. Why did the authors include a model in the paper?

3. Were parts of the model confusing?

4. How would conclusions of the paper have been different without the model?

Tuesday Sep 22

Adding complexity

For next time: be ready to pitch your idea for a model (prompt 3.2) to a group

Thursday Sep 24

Model simplification & thresholds

For next time: finish prompt 4.3 if we didn’t in class; work on group project

Tuesday Sep 29

Group work

For next time: finish group project & 10 min presentation
