BIEB 166: Animal Communication & Behavior Initials:____________________________ Page 2 of 9 total student points on this page:______ IMPORTANT! For multiple choice questions, there is only one correct or best answer per question. Circling more than one answer per question is incorrect. 1) (4pts) With regards to what we learned in lecture about killer whales, which of the following statements is correct ? (a) Transient whales live in groups of 10-25 whales. (b) Transient whales eat marine mammals (c) Transient whales often echolocate while foraging. (d) Resident whales tend to passively listen rather than echolocate. (e) None of these statements is correct. 2) (4pts) Which of the following statements is correct ? (a) When we speak of signal pattern loss, we refer only to how the amplitude modulation of a signal is affected. (b) Echoes are an example of a time domain source of signal amplification. (c) In sound shadow zones, sound reverberates and is thus distorted. (d) The SOFAR channel allows sounds to carry over great distances, in part, because sound waves propagate best through a zone of low sound velocities. (e) Animals living in open environments that are not subject to echoes tend to produce more slowly amplitude modulated signals than animals that live in dense environments that are subject to echoes. 3) (4pts) As discussed in the lecture with regards to mimicry , which of the following statements is correct ? (a) Batesian mimicry is imitation between species that are both dangerous. (b) Mullerian mimicry is the imitation of a dangerous model by a harmless mimic. (c) In negative frequency dependent selection, traits are selected against when they become too rare. (d) The butterfly, Heliconius melpomeme , has different forms and color patterns in different geographic locations (even though these are all the same species), probably because this strategy is a response to Batesian mimicry. (e) None of these statements is correct. 4) (4pts) Gould conducted a famous misdirection experiment to show that honey bees
