The following graph depicts the performance of 3 bird species (green, red, blue) as a function of prey size. The sizes of prey that can be consumed by each species are a function of the bill size, which is under genetic control.
(a) Which pair of species have the highest competitive overlap?
(b) Which pair of species have the least competitive overlap?
(c) Draw curve depicting the niche of a species that would coexist with all 3 of these species.
(d) Draw curve depicting the niche of a species that would coexist with ONLY the blue species (it would be excluded by either red or green).
(e) Draw a curve depicting the niche of a species that might cause the niche of the blue species to evolve in such a way that it would compete more with the red species than it does now.
