A Plant Metapopulation Exists Throughout the Floodplain of a Small

Multiple Choice

A plant metapopulation exists throughout the floodplain of a small river. Throughout this range it is pollinated by native beetle species, but the primary pollinator changes from a single species in the northern part of the range to a mix of species in the midrange and a different, single beetle pollinator in the southern part of the range. The southern beetle pollinator feeds on the flower corolla while laying its eggs; other beetle pollinators do not. In the midrange, flowers that are damaged by beetle herbivory are excised from the plant in favor of flowers that are pollinated by nonherbivorous beetles, but this does not occur in the southern part of the range. This is an example of ________ coevolution.

A) diffuse
B) antagonist
C) mosaic
D) mutualistic
