Chapter 51: Animal Behavior
Behaviors and Sensory
Dutch scientist that studied animal behavior and made 4 questions to understand animal behavior
How does the behavior help with survival and reproduction?
How does animal growth and development affect the response to the behavior
What is the behavior's evolutionary history?
What makes the animal do the behavior?
What parts of the animal body are involved with the behavior and its response?
Fixed Action Pattern
Unlearned, automatic responses to a single stimulus
(i.e. male stickleback fish gets protective & territorial when another comes near its nest)
This is due to the fish seeing something with a red color, producing an automatic response
The single stimulus that causes the response in a fixed action pattern
Long distance location change
Environmental cues often let the animal know when to migrate
(i.e. Nocturnal animals use the North Star to migrate)
A relative point that guides animal migration sometimes won't always be there (i.e. Sun)
The body rhythm helps adjust to this through its natural rhythm
Chapter 52: An Introduction to Ecology and the Biosphere
Around the equator (equatorial & sub-equatorial)
Tropical Dry Forest
Highly seasonal, 150-200 cm annually
6-7 month dry season
Tropical Rain Forest
Relatively constant, 200-400 cm annually
Broad-leaf evergreen trees often make the top layer
Bromeliads and orchids are most common in tropical rain forests
Millions of spiders, insects, amphibians, mammals, birds, etc.
