Just the facts ma'am

We didn't talk about equations for disturbance or changing carrying capacity, but actually they're pretty easy. We just need to modify the logistic growth equations a bit.

• To deal with changing carrying capacity, we'll say K _t instead of plain old K.
• To deal with disturbance, we'll add an extra equation to say that at the time of the disturbance, the population size drops to 5% of what it was just before.

 

That's all there is. We hope you enjoyed this module and got something out of it (in whichever order). Good luck on the quiz, and please leave us some feedback!
