I have posted a first set of study questions for the final exam (Click on link under Due Dates: Final Exam). There will be one "integrative question" from the list of candidates presented there. The rest of the exam will be as in our previous hour exams. I'll announce the location and time of the review sessions soon.

• Original habitat contains 52 species. This habitat can be deforested in two ways:
1. One fragment containing 50% of the original area.
2. Two fragments, each containing 25% of the original area.
• Using the species-area curve, calculate the number of total spp. remaining for each scenario.
• Which approach do you advocate? Do incidence functions matter for your conclusions?

Here are some additional math-type questions to help you study for the exam:

mm.in.bag<-c(1,10,350,150,30,60,50,650,70,90)

mm.eaten.2005<-c(0,3,8,6,5,7,6,6,6,5)
mm.eaten.2006<-c(2,2,10,4,11,6,10,17,8,8)
mm.eaten.mean <- apply(data.frame(mm.eaten.2005,mm.eaten.2006),1,mean)

1. Plot total and per-capita M&M predation as a function of M&M density
2. If you were an M&M, in which bag would you live
3. Are BIOL203 predators type II or type III predators? What do you think a type I predator would look like?

I've posted the exam key. I'll return exams in class tomorrow.

Using the realistic life history parameters for sea turtles given below. Calculate R0 for the following scenarios:

1. Increase survivorship of eggs/hatchlings to 1.0.
2. Absolute increase of 0.1 in juvenile survivorship.
3. Absolute increase of 0.1 in survivorship of breeders.
