Chapter 25, Problem 3DAA
Summary Introduction
To explain: Whether the results indicate that the lampreys detect and avoid the scent of dead lampreys.
Concept introduction: Sea lampreys are chordates that are classified as jawless fishes and are considered as the major parasitic carnivorous chordates. The sea lampreys are pests in the Great lakes of the USA as they cause loss of several commercial fishes.

Bats mostly hunt insects at night. They are able to determine the distance and speed of any prey they are chasing, which has helped them to become excellent nocturnal predators. One potential prey, the tiger moth, has developed two separate methods of evading predation.
First, tiger moths emit a toxin that is distasteful to bats, birds, and most other vertebrate predators. Second, they use an organ called a "tymbal" to create a series of high-pitched clicks that only bats can hear, and which identify the tiger moths as something the bats don't like to eat. Bats who prey on tiger moths discover they don't taste very good, learn to identify tiger moths by their clicks, and avoid eating them. Use this information to answer the questions below.
Question 1: The scenario above describes a distinct evolutionary interaction. What is it?Can you explain?
Question 2: Why is it necessary for the moth to produce both a tymbal click and a toxin? Why not just a toxin? Do you think there are…
"Although PTC is not found in nature, the ability to taste it correlates strongly with the ability to taste other bitter substances that do occur naturally, many of which are toxins."
Why would knowing if you are a taster or non-taster of PTC be important to survival in the wild?
Your answer:
How would you apply this in a Lamarckian explanation?
Tiger Moths (Bertholdia trigona) produce high pitched ultrasonic clicking (at a rate of 4500 clicks/sec) when they hear the echolocation calls of bats (bats eat moths). As a result, the bat's sonar is jammed and the Tiger Moth escapes without being caught, killed, and eaten. Please use your knowledge of Evolution by Natural Selection to explain the process by which this remarkable anti-predator defense evolved in Tiger Moths.

- Organisms have developed defense mechanisms to protect themselves from predation. These defense mechanisms include protective colouration Mullerian mimicry Batesian mimicry cryptic colouration chemical defense Match the following examples to the type of protective mechanism listed above.Stripes of a skunk AnswerA fawn with fur colouring that camouflages it in the forest AnswerTwo species of poisonous butterfly with the same colour pattern AnswerA hawkmoth with the same black and yellow body markings as a wasp Answerarrow_forwardPrey defenses often seem more specialized than the counter-defenses of their predators. Why?arrow_forwardBy 1935, hunting and trapping had eliminated wolves from the United States, except for Alaska. Wolves have since been protected as an endangered species, they have moved south from Canada and become reestablished in the Rocky Mountains and northern Great Lakes region. Conservationists who would like to speed up wolf recovery have reintroduced wolves into Yellowstone National Park. Local ranchers are opposed to bringing back the wolves because they fear predation on their cattle and sheep. What are some reasons for reestablishing wolves in Yellowstone National Park? What effects might the reintroduction of wolves have on the biological communities in the region? What might be done to mitigate the conflicts between ranchers and wolves?arrow_forward
- . In the summer of 2000, only 10 percent of the lobster population in Long Island Sound survived after a massive die-off.
