Study Notes
Animal Behavior Overview
- A behavior is the nervous system's response to a stimulus, carried out by the muscular or hormonal system.
- Animal behavior is subject to natural selection.
How to Study Animal Behavior
- Niko Tinbergen identified four key questions to understand animal behavior:
- What stimulus elicits the behavior, and what physiological mechanisms mediate the response?
- How does the animal's experience during growth and development influence the response?
- How does the behavior aid survival and reproduction?
- What is the behavior's evolutionary history?
- Behavioral ecology studies the ecological and evolutionary basis of animal behavior.
Fixed Action Patterns
- Fixed action patterns are sequences of unlearned, innate behaviors that are unchangeable.
- They are initiated by a sign stimulus, an external cue, and usually carried to completion.
- Example: Male stickleback fish attack other males, triggered by the red underside of an intruder (not just any color).
Migration
- Migration is a regular, long-distance change in location.
- Environmental cues trigger movement in a particular direction.
- Animals orient themselves using:
- the position of the sun and their circadian clock
- the position of the North Star
- Earth's magnetic field (magnetite).
Animal Signals and Communication
- A signal is a behavior that causes a change in another animal's behavior.
- Communication is the transmission and reception of signals.
- Animals communicate using visual, chemical, tactile, and auditory signals.
- Example: Fruit fly courtship involves chemical, visual, tactile, and auditory signals.
Honeybee Communication
- Honeybees exhibit complex communication with symbolic language.
- A bee returning from the field performs a dance to communicate information about the distance and direction of a food source.
- Round dance: Food is near.
- Waggle dance: Food is distant.
Types of Animal Behavior (Learning)
- Imprinting
- Cognition
- Learning and problem-solving
- Spatial learning
- Associative learning
- Social learning
Imprinting
- Imprinting is a behavior that combines learning and innate components and is generally irreversible.
- It is distinguished by a sensitive period, a limited developmental phase when certain behaviors can be learned.
- Example: Konrad Lorenz and geese.
Spatial Learning and Cognitive Maps
- Spatial learning is a complex behavior modification based on environmental experiences.
- Animals use landmarks to find their way.
- A cognitive map is an internal representation of spatial relationships between objects in an animal's surroundings.
- Example: Digger wasps use landmarks.
Associative Learning
- Animals associate one feature of their environment with another.
- Classical conditioning: An arbitrary stimulus is associated with a reward or punishment.
- Example: Pavlov's dogs, associating a bell with food.
- Operant conditioning (trial-and-error learning): An animal learns to associate a behavior with a reward or punishment.
- Example: A rat pushing a lever to receive food.
Cognition and Problem Solving
- Cognition is a knowing process which includes awareness, reasoning, recollection, and judgment.
- Animals can distinguish between "same" and "different".
- Example: Honeybees choosing the correct color.
Problem Solving and Social Learning
- Problem-solving is devising a strategy to overcome an obstacle.
- Social learning involves learning from the observation of others and forms the basis of culture.
- Example: Chimpanzees stacking boxes to reach food, Young chimpanzees learning to crack palm nuts.
- Example: Vervet monkeys using alarm calls for different predators
Genetic Basis of Behavior
- A master regulatory gene can control many behaviors.
- Multiple independent genes contribute to a single behavior.
Altruism
- Natural selection favors behavior that maximizes an individual's survival and reproduction.
- Altruism is a behavior that reduces an individual's fitness but increases the fitness of others.
- Example: Belding's ground squirrels giving alarm calls, Naked mole rats sacrificing for their colony.
Hamilton's Rule and Kin Selection
- Hamilton's Rule quantitatively predicts when natural selection would favor altruistic acts among related individuals.
- Reciprocal altruism occurs in species with stable social groups where individuals meet repeatedly and cheaters are punished.
