Title: Chapter 6 Behavioral adaptations for survival
1Chapter 6 Behavioral adaptations for survival
21. What is an adaptationist approach
- Constraints
- 1. Mutation failure
- 2. pleiotrophy
- 3. coevolution
- Definitions
- Fitness higher reproductive success
- Adaptation physiological changes to enhance
fitness
36.1 Mobbing behavior of colonial, ground-nesting
gulls
- Predator distraction hypothesis
- Eggs survive better because predators cant focus
on finding them on the ground when mobbed.
46.3 Does mobbing protect eggs?
56.4 Benefit of high nest density for the arctic
skua
62. How does the comparataive method work? Use
Gull phylogeny and two scenarios for the origin
of cliff-nesting behavior as an example (Part 1)
76.5 Gull phylogeny and two scenarios for the
origin of cliff-nesting behavior (Part 2)
86.6 Not all gulls nest on the ground
96.7 The logic of the comparative method
103. What is convergent evolution ? Why are
Colonial California ground squirrels an example
of convergent evolution?
116.9 Evidence for a cost of parental mobbing
behavior
126.12 Fighting back by terns and wasps
136.13 Communal defense by sawfly larvae
146.14 A group of sleeping bees
154. What is a cost-benefit approach? Use the
dilution effect in butterfly groups as an
example.
166.10 The dilution effect in butterfly groups
(Part 2)
176.11 The dilution effect in mayflies
185. What are the costs and benefits of
camouflague? Cryptic coloration depends on
background selection
196.16 The camouflaged moth, Biston betularia
206.17 Predation risk and background selection by
moths
216.18 Cryptic coloration and body orientation
226.19 Does cryptic behavior work?
236.23 Effect of monarch butterfly toxins
246.20 The value of a backpack (Part 1)
256.20 The value of a backpack (Part 2)
266. What is a Darwinian puzzle? How does Warning
coloration demonstrate this?
276.24 Why behave conspicuously?
287. What is "stotting"?
List and explain 4 alternative hypothesis to
explain stotting? Which do you think the data
supports?
29Alternative hypothesis for stotting
- Alarm signal
- warn conspecifics
- Social cohesion
- form groups and flee together
- Confusion effect
- Keep predator from fleeing
- Pursuit deterrence
- Allow predators to evaluate condition
