Chapter 43, Problem 1DAA
Summary Introduction

To determine:  The number of birds that gave the alarm call.

Introduction: Aggressive mimicry is a kind of mimicry in which the predators or parasites share the similar signals to avoid them being correctly identified from the predators.

Explanation of Solution

Organisms defend themselves using the aggressive mimicry like peacock butterflies. They open their wings to reveal their large eyespots that are hidden when the butterfly is at rest. The hypothesis on the predators mimicry states that the eyespots frighten a predatory bird mimicking the eyes of the bird’s predators to avoid themselves from the risk of being hunted. Person R presented peacock butterflies with or without the eyespots painted over the domestic chickens. They also recorded whether the chickens gave an alarm call to sighting the predator.

Refer to Fig. 43.9 “Response of domestic chickens to the defense display of a peacock butterfly” in the text book. The graphical representation shows the number of butterflies with or without eyespots painted over in X-axis and their treatment was given in Y-axis. When the eyespots were visible, the number of birds that gave an alarm call was approximately 12 to 14.

Conclusion

When the eyespots were visible, the number of birds that gave an alarm call was 12 to 14.

Summary Introduction

To determine: The number of birds that did not give an alarm call when the eyespots were visible.

Introduction: Information transmission is done through communication signals. These signals persist if the response benefits the sender and the receiver. If a sender or receiver fails to send signals, then any one of the individuals will be affected.

Explanation of Solution

Organisms defend themselves using the aggressive mimicry like peacock butterflies. They open their wings to reveal their large eyespots that are hidden when the butterfly is at rest. The hypothesis on the conspicuousness of predators mimicry states that the eyespots frighten a predatory bird mimicking the eyes of the bird’s predators to prevent themselves from the risk of being hunted. Person R presented peacock butterflies with or without the eyespots painted over the domestic chickens. They also recorded whether the chickens gave an alarm call to sighting the predator.

Refer Fig. 43.9 “Response of domestic chickens to the defense display of a peacock butterfly” in the text book. The graphical representation shows the number of butterflies with or without eyespots painted over in X-axis and their treatment was given in Y-axis. The number of birds that remained silent was approximately 10 to 12.

Conclusion

When the eyespots were visible, the number of birds that remained silent was approximately 10 to 12.
