Since many of you were unable to make lab today, I have posted a help page for interpreting your findings for lab 6. The lab itself is straightforward in execution, but there are a few concepts that may be tricky to understand.
Each of the four questions are nearly identical except for changes in the α and β values. α and β in Populus is equivalent to α1←2
and α2←1 respectively as used in the class notes.
Lotka-Volterra Model for species competition.
The significance of these coefficients has to do with their values with respect to 1.
What does it mean when α or β > 1?
What does it mean when α or β < 1?
To answer part E of each question, referring to your exploration in part D, you’ll need to refer to the properties of Competitive Coexistence.
From your notes, the definition for competitive coexistence is when K1>αK2 and K2>βK1.
Lab Reports:
This lab focuses mostly on the Why? components of each question. Think critically and use these hints as well as your notes to interpret the models.
I don’t need any graphs with this lab, but be sure to answer each part of the question completely.
Lab reports will be due at Midnight on Thursday, March 24.
