Exam 6: Communication

In Scientific Process 6.2, over time, males in good condition reduced their display rate to females in poor condition. One hypothesis to explain this observation is that males assessed female condition over repeated interactions and reduced display rate as they determined that the female was in poor condition. Explain how a male can benefit by reducing display activity to a poor quality female.

What evidence led Riley and colleagues (2005) to suggest that bees respond to the waggle dance rather than odor cues?

Hoefler and colleagues (2009) concluded that male spider leg raise displays are an indicator of quality to females. What assumption underlies this conclusion?

What data allowed Abrahams, Robb, and Hare (2005) to conclude that opercular flare displays are an accurate indicator of male fighting condition?

Which of the following is NOT true of the vervet monkey and tufted titmouse alarm call systems?

Which of the following is NOT true about the honeybee waggle dance?

Define extended phenotype signal and give one example.

Which of the following is NOT true about the sexual deception hypothesis and false alarm calls produced by topi?

Which of the following is NOT associated with Batesian mimicry?

Auditory signals______________.

Which of the following is NOT a condition that favors the evolution of signals that are accurate indicators of conditions?

Explain the difference between an audience effect and eavesdropping.

What observation allowed Schmidt and Ostfeld (2008) to conclude that squirrels eavesdrop on blue jay auditory signals?

What experimental result allowed Kuchta, Krakauer, and Sinervo (2008) to conclude that Ensatina eschscholtzii xanthoptica is a Batesian mimic?

Which of the following is NOT associated with communication networks?

How did Suzanne Gray and colleagues (2008) examine the evolution of signals in fish?

Which of the following is always associated with the production of false alarm calls?

How did Saporito and colleagues (2007) conclude that the bright coloration of O. pumilio frogs functions as an aposematic signal?

Explain why extended phenotype signals are considered to be reliable indicators of conditions.

If you found a new bird species that lived in dark forest habitats in the Amazon, which of the following would you predict to be the most likely way that males attract females?
