1. Behavioral Ecology
Big Idea 2E: Many biological processes involved in growth, reproduction, and homeostasis include temporal regulation and coordination

2. Essential Knowledge
2E3: Timing and coordination of behavior are regulated by various mechanisms and are important in natural selection.

3. Science of studying animal behavior
Ethology
Science of studying animal behavior

4. Orgs. can act on info and communicate it to others

5. Innate Behaviors: behaviors that are inherited.
Can do this through…
Innate Behaviors: behaviors that are inherited.

6. Or through…
Learned Behaviors: Behaviors that are learned through interactions w/ the env. and other orgs.

7. Survival!
Is dependent upon an orgs ability to respond to info and communicate  natural selection

8. Ex: Evolution of Phototropism
This response allows plants to move w/ sun to gain maximum exposure to light for PS.

9. Ex: Evolution of Photoperiodism
Changes in length of night regulates flowering and preparation of winter.

10. Behaviors are Triggered by Environmental Cues
Necessary for reproduction, natural selection, and survival.

11. What is the environmental cue here to start this behavior?

12. What do I want to get away from?
Estivation
What do I want to get away from?
Turtles estivate to get away from heat or cold
A hibernation behavior in which an org is trying to escape an event in their env.

13. Migration A temporary movement; move back and forth from a place
Grey whales in Pacific. Births in Mexico, go north to Arctic to get good krill!
A temporary movement; move back and forth from a place
Why do whales migrate? What is the cue?

14. Cooperative Behavior is Needed!
Contributes to the survival of a population.

15. Ex: Altruism
An animal’s behavior decreases its fitness, but increases fitness for others.
Ex: ground squirrel gives off alarm when sees a coyote  warns others, but increases its chances of dying.

16. Ex: Mutualistic Relationships
Lichens: A fungus and a photosynthetic partner.
Increases survival of both pops.

17. Simple random change in activity in response to a stimulus.
Lab Stuff: Kinesis
Simple random change in activity in response to a stimulus.
Ex: Sow bugs: Like moist areas. When in a moist area  slowly move so that they don’t leave it.

18. Lab Stuff: Taxis Automatic movement to or away from a stimulus.
To the stimulus  positive taxis
Away from stimulus  negative taxis
Ex: Trout: swim upstream (food and egg laying)
