9/8 Daily Catalyst Pg. 11 Behavior 1. Compare and contrast age diagrams A and B. 2. What can you infer about the countries that age diagrams A and B are representing? 3. Describe age diagrams A and B using the words life expectancy and mortality.

9/8 Daily Catalyst Pg. 11 Behavior 1. Compare and contrast age diagrams A and B. Diagram A has a higher percentage of their population under the age of 20. Diagram B has a higher middle aged population. 2. What can you infer about the countries that age diagrams A and B are representing? Country A is developing. Healthcare access declines as one ages. Physical labor workers. Country B is developed. Most likely has better access to education and healthcare 3. Describe age diagrams A and B using the words life expectancy and mortality. Diagram A has increased elderly mortality versus diagram B which has a higher life expectancy.

Why is studying animal behavior essential to the survival of humans? Essential Question Why is studying animal behavior essential to the survival of humans?

The modern scientific discipline of behavioral ecology Extends observations of animal behavior by studying how such behavior is controlled and how it develops, evolves, and contributes to survival and reproductive success Called Ethology Ask why I have part of this statement bolded? I have this statement bolded, because, ecology is all about life interacting with non-life, but at the end of the day, AP Biology cares if we can associate ecology with evolution and behavior ecology is a great tie to show us the connection between how organisms interact with the environment and how this interaction may be genetically linked and those genes that are able to be passed on are essential for survival which is natural selection. Ethology is the study of animal behavior, especially in their natural environment.

What Is Behavior? Key Point #1: Define behavior Is what an animal does and how it does it Includes muscular and nonmuscular activity Dorsal fin Anal fin Muscular is movement and nonmuscular is secreting chemicals, hormones, or changing colors (chemical or predation like camo for warning)

What is a probable cause for many animals reproducing in the spring? Turn and Talk What is a probable cause for many animals reproducing in the spring? Longer day length, mates are closer (hibernation and return from migration), warmer temperatures, increased food supply, and better chance for offspring to survive which natural selection and passing the “good” survival traits.

Imprinting Kinesis Taxis Migration Communication Behaviors to Know! Imprinting Kinesis Taxis Migration Communication Chemical Communication Auditory

Imprinting Key Point #2: Phase-sensitive learning period that is independent of consequences Irreversible Sensitive period: specific time to learn behavior Example: Geese and Lorenz

Innate Definition: Developmentally fixed behaviors Example: instincts

Kinesis Key Point #3: Simple change in activity due to stimulus Non-directional THIS IS NOT TAXIS! Example: Sow bugs like humidity! They simply just move and if they land in humidity, they stop moving. Example: When you turn on the light, cockroaches will scatter to whatever direction!

Taxis Key Point #4: Autonomic movement to or away from stimulus Directional THIS IS NOT KINESIS! Example: Trout purposely move upstream to catch food.

Migration Key Point #5: Movement to new habitat Genetically linked (like eye color) Example: Black cap birds move to a certain new habitat at specific times of the year Do all birds migrate?

Communication Eye Point #6: Signal that causes a change in others behavior Examples: visual, auditory, chemical, tactile, electrical signals

Chemical Communication Key Point #7: Due to genetics Pheromones Example: Bees reproducing with certain bees and not others Example: Fish secrete chemicals when injured to warn others

Auditory Communication Key Point #8: Genetics even if isolated! Example: bird song of reproduction

Nature vs. Nurture Vs.? NOPE! All may have the same phenotype for behavior, but in different environments we act differently. Example?

Explain the cartoon As smart as think we are, other animals are just as smart. So the dog is conditioning Pavlov to write down information when the stimulus is dog drooling.
