Bouchard and Brooks Studied the Effect of Insect Flight on Dispersal

question 12

Multiple Choice

Bouchard and Brooks studied the effect of insect flight on dispersal and speciation in rain forest insects.They sampled all of the insects in the study area and found that 60 insect species are flightless and 19 are macropterous (able to fly) .After analyzing the results of the Bouchard and Brooks (2004) study,you conclude that macropterous and flightless insects in the rain forests of northeastern Australia have dispersed and speciated in similar manners.What does this say about flight in these insects?

• A)Flight,although used for locomotion,is not increasing the species dispersal efficiency in this community.
• B)Flight is not important in these insects for success.
• C)Flight is important only for mating.
• D)Flight is only factor involved in speciation in those insects with flight,and thus it is not important for dispersal of these species.
• E)Nothing further can be said about flight.
