One frightening device under consideration is a bio-acoustic device that would mimic animal<br />
communication signals such as alarm or distress calls. These devices typically consist of an infrared<br />
detection system, which activates an audio component that broadcasts recorded alarm or distress calls.<br />
An alarm call is used to warn others of possible danger; a distress call is emitted when an animal is<br />
physically traumatized or restrained. Researchers have studied the effects of such devices on birds, but<br />
little is known of their effect on mammals. If effective with deer, bio-acoustic alternatives would meet<br />
with public approval and in addition could be used in both rural and urban settings.<br />
You are to design an experiment to test the hypothesis that sound devices can reduce deer<br />
predation on corn. For purposes of this experiment every right-thinking Iowa farmer has volunteered<br />
his acreage for use as test plots; you have complete freedom to choose cornfields for treatment and<br />
control plots. Not only that, every right-thinking Iowa parent has volunteered their teenagers’ boom<br />
boxes (in hopes that you are conducting a multi-year experiment.) These boom boxes came in various<br />
brands, with the Aiwa CD player (model CDC-X217) being the most popular. Infra-red animal-activated<br />
alarm and distress call systems have been purchased from the Charles River Universal Scientific<br />
Technical Yard (CRUSTY) and the corn yield will be measured by yield monitors linked to Global<br />
Positioning Systems on harvesting equipment.<br />
Deer are most active at dusk and dawn, and are frequent feeders at night. They tend to stay close<br />
to wooded areas for safety; farms in Iowa are frequently interspersed with wooded areas.
