Question
Chapter 55.2, Problem 1R
Summary Introduction
To review:
The avoidance mechanisms that can be evolved in the small reel fish so that they can escape being eaten by the lionfish.
Introduction:
There is a need for certain defense mechanisms in the organisms that are in the threat of being eaten by their predators. In order to protect themselves from the newly emerged predator lionfishes, the small coral reef fishes must develop certain mechanisms that enable them to avoid the predators and help in their survival.

Describe the behavior of fish in these four scenarios:
a. Undisturbed
b. Few pebbles are dropped
c. Fish food are dropped
d. Tank is tapped on one side
If the rate of some process is governed by the abundance of prey individuals, we say that it is prey-dependent. Give some examples of prey-dependent processes.
DRAW IT You are considering two optimal foraging models forthe behavior of a mussel-feeding shorebird, the oystercatcher. Inmodel A, the energetic reward increases solely with mussel size.In model B, you take into consideration that larger mussels aremore difficult to open. Draw a graph of reward (energy benefiton a scale of 0–10) versus mussel length (scale of 0–70 mm) foreach model. Assume that mussels under 10 mm provide nobenefit and are ignored by the birds. Also assume that musselsstart becoming difficult to open when they reach 40 mm inlength and impossible to open when 70 mm long. Consideringthe graphs you have drawn, indicate what observations andmeasurements you would want to make in this shorebird’shabitat to help determine which model is more accurate.

- Explain how zooplankton avoid predation through vertical migration.arrow_forwardDo the following two hypothesis supports their graphs? Explain. Figure 1: The hypothesis for novice vs. experienced foraging is that animals who have been foraging for ages should have a greater chance of survival than beginner foragers since they are more skilled and invest less time looking for food. Figure 2: The hypothesis behind the impact of Prey camouflage is that if animals, especially novice foragers, take too much time searching, they are visible to predators for long durations, providing a better chance to attack.arrow_forwardThink back to Section 44.6. When researchers moved guppies from populations preyed on by cichlids to a habitat with killifish, the life histories of the transplanted guppies evolved. They came to resemble those of guppy populations preyed on by killifish. Males became gaudier; some scales formed larger, more colorful spots. How might a decrease in predation pressure on sexually mature fish allow this change?arrow_forward
