Packet 13- Diversity of Kingdoms
Pg. 7-8

2. What is an Animal?
Multicellular which means they are made up of more than once cell.
Eukaryotes which means their cells are more complex…each contains a protective area for their genetic material (called a nucleus) and many other structures with specialized tasks called organelles.

3. What is an Animal?
Called heterotrophs because they must consume other organic materials to meet their nutritional needs (unlike plants, they cannot make their own food).

4. Notes: Animal Behavior

5. Behavior- the way an organism reacts to change or a stimulus (internally or externally)
Stimulus- something that causes a change or response
Taxis- the response of an organism moving away or toward something (ex. Phototaxis….light)

6. Taxis
Chemotaxis: Bacteria moving towards a high concentration of food molecules.
Phototaxis: Moving in response to light.

8. Behavior is generally divided into two types:
1. Innate behavior- behavior that has a genetic basis and does not need to be taught.
A baby crying, a spider building its web,

9. Suckling
A mammal nursing from its mother right after its born.

10. 2. Learned behavior- must be observed or taught to acquire the behavior

11. Habituation learning to ignore a stimulus
(ex. If you live next to the train tracks you probably are unaware of trains as they pass- you become desensitized)

12. Classical Conditioning- The act of associating one stimulus with another
Ivan Pavlov- Experiment w/dog that showed classical conditioning

13. Before conditioning- dog drooled at the sight of food
During conditioning- Pavlov rang the bell every time he fed the dog
After conditioning- All Pavlov had to do to get the dog to drool was ring the bell. The dog associated the bell with food.

14. Operant Conditioning (also referred to as Trial & Error)
Learning to behave through repeated practice in order to receive a reward or avoid a punishment

15. Skinner Box- lever or button that delivered a food reward when pressed

16. Insight or reasoning- most complex learned behavior.
This occurs when an animal applies something it has already learned to a new situation, without a period of trial and error.

17. Imprinting
Learning based on early experience; once imprinting has occurred, the behavior cannot be changed.
complex response that is a combination of innate & learned behaviors
Young animals have an innate urge to follow the first moving object they see. They must then learn through experience what object to follow (ex. Baby geese following a human)
Imprinting can also occur through smell

19. Or as you may know it….

20. Patterns of Behavior
Cycles of Behavior- behaviors that repeat in a predictable manner
Migration- seasonal travel for reproduction and feeding (Immigration= in; Emmigration = exit/out)

21. Circadian Rhythms- Daily/24-hour cycles
Ex. Sleep cycle
Diurnal- active during the day/sleep at night

22. Nocturnal- sleep during the day/active at night.
The fact that you sleep at night and go to school during the day is an example of circadian rhythm.

23. Hibernation- a state of inactivity in animals, used to survive during Cold temperatures; characterized by lower body temp, slower breathing and lower metabolic rate. Hibernation conserves energy, especially during winter.

24. Estivation- used to survive extreme heat/drought; a state of dormancy similar to hibernation

25. Courtship behaviors- ways of attracting mates through sounds, sight or smell
Some mating behaviors include rituals, or an elaborate series of behavior used for communicating with other members of the species.
Example: fireflies flashing their lights is a way of letting other fireflies know that they are ready to mate.

26. Birds of Paradise

27. Competition and Aggression- helps prevent some animals from using limited resources. Often involves a specific area or territory.
Territoriality: Protecting territory

28. Social Behavior- living with closely related animals and helping them survive. Increases the chance of the ‘family genes’ being passed on to the next generation.
Common examples include social insects such as ants, bees, and termites.

29. Jane Goodall- Behaviorist responsilbe for the foundation of primate studies today. She began her work in the 1960s observing the social behavior or chimpanzees in the wild.

30. Communication- Passing of information from one organism to another w/sight, sound, touch, or chemical signal (ex-pheromones)

31. Pheromones- A chemical signal that causes a response in another animal
Exx.1. a chemical in the ink elicited the trailing behavior in the termites;
Ex 2. male elephants produce a pheromone that attracts female elephants…however too much pheromone repels the female)

32. Visual signals such as movement or colors.

33. Sound signals used by animals such as crickets, toads, birds, and dolphins.

34. Language- only used by humans (learned/taught- not innate)
