Question

Which of the following did not contribute to Mike Ryan's scientific method in work on frogivorous bats (based on information from class and the reading)?

a. The observation that bats eat tungara frogs.
b. An experiment using speakers to broadcast simple and complex frog calls to bats.
c. An experiment to compare rates of bat predation on tungara frogs versus mice.
d. The use of laboratory flight cages to test the behavioral responses of individual bats.
e. The observation that tungara frogs attract blood-sucking flies.

Answer 1

Mike Ryan's work did not involve comparing bat predation rates on tungara frogs with those on mice; his studies targeted the specific interactions between frogivorous bats and tungara frogs.

Step-by-step explanation:

The option that did not contribute to Mike Ryan's scientific method in work on frogivorous bats is c. An experiment to compare rates of bat predation on tungara frogs versus mice. Mike Ryan's research primarily focused on the interactions between bats and their prey, the tungara frogs, particularly looking at the frogs' mating calls and how they influence bat predation. Ryan's work included observations of bat feeding habits, experiments using speakers to test the response of bats to frog calls, and the behavioral analysis of bats in laboratory conditions.

However, there was no mention of comparing predation rates on frogs to those on mice, which would not be directly relevant to studying frog-bat interactions.
