The mathematics of Coexistence

Question 1

True or False:

The model of competition between species can ignore competition within species.

Answer 1

False

Question 2

True or False:
The larger the competitive effect on a species (alpha or beta), the more likely the species will persist during competition.

Answer 2

False

Question 3

True or False:

When two species have different niches, the competition coefficients (alpha and beta) are likely to be less than 1.0.

Answer 3

True

Question 4

True or False:

If two species compete, neither species will reach its carrying capacity before one species goes extinct.

Answer 4

True

Question 5

True or False:

The population growth rate (r) determines whether a species can persist during competition.

Answer 5

False

Question 6

True or False:

A realized niche is usually larger than a fundamental niche.

Answer 6

False
