Chapter 2 Flashcards
What is a testable explanation for observed phenomenon?
Hypothesis
Which of the following is a hypothesis?
a) How do male wolf spiders find unmated females
b) Male wolf spiders use behavior of nearby males to find receptive females
c) Presence of rival male searching male orienting toward the rival, searching for a female and beginning courtship tapping
b) Male wolf spiders use behavior of nearby males to find receptive females
Mathematical models can generate predictions about which behaviors maximize an individual fitness
All models are based on assumption about ecology and evolution of organism
hypothesis
Squirrel foraging: Carrying food creates tradeoff safety vs energy
1) Fitness increases with higher energy intake rate
2) fitness increases with less time spent away from cover
3) squirrels are safe in a tree and at risk of death away from trees
4) larger food items require longer handling time
Predictions squirrel foraging: As food size increases carrying to safety increases handling time
as distance to safety tree increases carry less
No manipulation (lack control)
Observation
Manipulation of variables
-Must have control group to evaluate the effect of the manipulation
experimental
Compare behaviors around species
- Assessment of ancestral vs derived traits
-timing of development of the behavioral trait
comparative
Seahorse are considered?
a) Subordinate
b) coursing
c) Monagomous
d) independent
Monagomous
What are species that have daily greeting ritual?
a) Subordinate
b) monogamous
c) dominant
d) independent variable
Monagomous
