Question

Are toucans important to tropical forests? Human activities are causing the fragmentation of the Brazilian Atlantic rain forest. One consequence is that toucans have become extinct or nearly extinct in some of the forest fragments. Does the absence of toucans affect the forest? Part A Ecologist Mauro Galetti and his colleagues measured the seed sizes of p in forest fragments with and without toucans. The graphs show two of the forest populations they studied Toucans present Toucans absent 30 80 25 20 60 15 40 10 20 8 10 12 14 10 12 14 Seed diameter (mm) Source: Galetti, M., R. Guevara, and M. C.

Explanation / Answer

This statement is true. This data has shown in the reduction of diameter of seeds but has not shown in how much course of time. Since evolution is a slow process, therefore time period should be mentioned. Moreover possibility of other factors in forest fragmentation other than human activity should be ruled out. These things if gets included will strengthen the results and protect other species as well.
