This is an outline of what is involved in the Home Labs for this course.
|Home Lab||Title||Learning Objectives||Estimated Time to Complete|
|1||Temperatures and Microclimates||Measure and graph a temperature profile.||2-6 hours|
|2||Intra- and Interspecific Competition||Conduct an experiment on the effects of competition (for space, nutrients and light) within and between two plant species. Summarize the results with a graph.||12-16 hours over 4-5 weeks|
|3||Predator-Prey Modeling i.e., Holling disc equation and the density dependent functional response of a "predator" (a human's finger or pencil) and "prey" (squares of sandpaper).||In general, determine that an equation can mimic or predict reality. Specifically, to simulate (= model) a simple, density dependent predator-prey interaction, i.e. how a prey's abundance can affect a predator's ability to capture the prey, in other words, the predator's functional response to prey density.||4-6 hours (involves 2 people, a "predator" and an observer)|
|4||Sampling with Quadrats
1. Minimum area of a quadrat
2. Minimum number of quadrats
3. Performance curve
6. Dominance or cover
7. Importance value
|Learn the basics of quadrat sampling including how size of quadrats affects sampling and how different population attributes can be determined.||3 hours|
The first three of the four Home Labs are done with materials that students supply. Such materials include a thermometer, metre stick, graph paper, seeds and plant growing materials. We expect that the average extra cost of student-provided materials will be less than $30. The fourth Home Lab is a pencil and paper exercise.
