Now assume that ALL of the islands had extremely high plant herbivory (and each island has the same herbivore pressure). What would this do to extinction rate for all 3 islands? Which island would have the greatest species richness? Demonstrate by graphing all 3 islands on the graph below (be sure to label axes, lines, points). (8 pts) Extinction rate
Homework Answers
First of all we need to understand basic principles of species richness in insular geography (islands).
Add Answer to:
Island A is 100 m and 1000 m from the mainland. Island B is 50 m2 and 1000 m from the 1) mainland. Island C is 50 m2 a...

2. Consider the following four consumers (C1,C2,C3,C4) with the following utility functions: Consumer Utility Function C1 u(x,y) = 2x+2y C2 u(x,y) = x^3/4y^1/4 C3 u(x,y) = min(x,y) C4 u(x,y) = min(4x,3y) On the appropriate graph, draw each consumer’s indifference curves through the following points: (2,2), (4,4), (6,6) and (8,8), AND label the utility level of each curve. Hint: Each grid should have 4 curves on it representing the same preferences but with different utility levels. 3. In the following parts,...
