LAB 6 - Animal Behavior Flashcards
What are the 2 types of stimuli?
- external EX: sight of a predator
- internal EX: hunger
(3. mixture) EX: mating behavior
What is innate behavior?
-inborn, hereditary
What are 4 types of innate behaviors?
- reflexes
- taxes
- instincts
- FAPs
What is learned behavior?
depends on experience
What are 3 types of learned behaviors?
- imprinting
- habituation
- conditioning
What is a proximate cause?
- immediate cause of behavior
- immediate physiological response that leads to a behavior
What is an ultimate cause?
-adaptive value (evolutionary adaption
EX: bird migration
What is taxis?
- directional movment in response to a stimulus
positive: toward
negative: away
What is phototaxis?
light (planaria)
What is geotaxis? (or gravitaxis)
gravity (fruit flies)
What is rheotaxis?
against the current (salmon)
What are 4 other types of taxis?
- hydro
- thigmo
- chemo
- thermo
What is kinesis?
- non-directional, random movement
positive: increase in movement
negative: decrease in movement
What is hygrokinesis?
- a change in the rate of movement of an organism
- response to change in humidity
What is agonistic behavior?
-display that results in an animal looking big or threatening
What is the goal of agonistic behavior?
- maintain the territory
- keep access to all resources (space, food, mates)
What is a threat?
intimidation
What is aggression?
force
What is submission?
retreat or avoidance
What is reproductive behavior?
- find a mate, courting, and mating
- species specific
What organism was used to text phototaxis?
Black planaria (freshwater flatworms)
What organism was used to test chemotaxis?
Paramecium caudatum (freshwater protist, ciliate)
Did planaria have a positive or negative phototaxis?
negative
Did the paramecium have positive or negative chemotaxis for glycine and acetic acid?
glycine (positive) acetic acid (negative)
What organism was used to test agonistic behavior
Betta splendens
What are agonistic behaviors of Betta splendens?
- flare fins, puff out girl covers
- color of fins enhanced
What is behavior?
-response of an organism to spec. stimulus in environment
What is the purpose of behavior?
-physiological response to maintain homeostasis
What is homeostasis?
-organism’s tendency to keep internal conditions constant
