Biodiversity models Flashcards
1
Q
What is the Arrhenius species-area model?
A
As area increases, so does the number of species
S = cA2 S = species c = constant A = area
If you take natural logs, the equation will be linear
2
Q
What happens as an island gets further from other land masses?
A
Generally, the number of species decreases
3
Q
When do you use multiple regression?
A
When testing 2 or more hypotheses simultaneously e.g. both area size and isolation to see whether they are both significant
