What Is Behavior?–Is what an animal does and how it
does it

Behavior 1: Fixed Action Patterns
• A fixed action pattern (FAP)– Is a sequence of unlearned, innate behaviors that is
unchangeable– Once initiated, is usually carried to completion
• A FAP is triggered by an external sensory stimulus– Known as a sign stimulus
![Page 12: Sep 7: Animal behavior (Ch 51). Dispatch 9/7 1) What is the difference between NPP and GPP? 2) How are cellular respiration and photosynthesis similar?](https://reader035.vdocument.in/reader035/viewer/2022062309/5697c0251a28abf838cd5285/html5/thumbnails/12.jpg)
• In male stickleback fish, the stimulus for attack behavior is the red underside of an intruder
Figure 51.3a
(a) A male three-spined stickleback fish shows its red underside.
![Page 13: Sep 7: Animal behavior (Ch 51). Dispatch 9/7 1) What is the difference between NPP and GPP? 2) How are cellular respiration and photosynthesis similar?](https://reader035.vdocument.in/reader035/viewer/2022062309/5697c0251a28abf838cd5285/html5/thumbnails/13.jpg)
Activity: What will you, as the male stickleback do in each scenario?
Scenario 1 Scenario 2
Scenario 3 Scenario 4
![Page 14: Sep 7: Animal behavior (Ch 51). Dispatch 9/7 1) What is the difference between NPP and GPP? 2) How are cellular respiration and photosynthesis similar?](https://reader035.vdocument.in/reader035/viewer/2022062309/5697c0251a28abf838cd5285/html5/thumbnails/14.jpg)
• When presented with unrealistic models– As long as some red is present, the attack behavior
occurs
Figure 51.3b
(b) The realistic model at the top, without a red underside, produces no aggressive response in a male three-spined stickleback fish. Theother models, with red undersides, produce strong responses.
![Page 15: Sep 7: Animal behavior (Ch 51). Dispatch 9/7 1) What is the difference between NPP and GPP? 2) How are cellular respiration and photosynthesis similar?](https://reader035.vdocument.in/reader035/viewer/2022062309/5697c0251a28abf838cd5285/html5/thumbnails/15.jpg)
Proximate and ultimate causes for the FAP attack behavior in male stickleback fish
Figure 51.4ULTIMATE CAUSE: By chasing away other male sticklebacks, a male decreasesthe chance that eggs laid in his nesting territory will be fertilized by another male.
BEHAVIOR: A male stickleback fish attacks other male sticklebacks that invade its nesting territory.
PROXIMATE CAUSE: The red belly of the intruding male acts as a sign stimulusthat releases aggression in a male stickleback.

Behavior 2: Imprinting
• Imprinting is a type of behavior– That includes both learning and innate components
and is generally irreversible
• An example of imprinting is young geese– Following their mother
BEHAVIOR: Young geese follow and imprint on their mother.

Activity: What will you, as the recently hatched duck, if instead of mommy duck a
chicken is present?
![Page 18: Sep 7: Animal behavior (Ch 51). Dispatch 9/7 1) What is the difference between NPP and GPP? 2) How are cellular respiration and photosynthesis similar?](https://reader035.vdocument.in/reader035/viewer/2022062309/5697c0251a28abf838cd5285/html5/thumbnails/18.jpg)
• Konrad Lorenz showed that–When baby geese spent the
first few hours of their life with him, they imprinted on him as their parent
![Page 19: Sep 7: Animal behavior (Ch 51). Dispatch 9/7 1) What is the difference between NPP and GPP? 2) How are cellular respiration and photosynthesis similar?](https://reader035.vdocument.in/reader035/viewer/2022062309/5697c0251a28abf838cd5285/html5/thumbnails/19.jpg)
• Conservation biologists have taken advantage of imprinting– In programs to save the whooping crane from
extinction
Figure 51.6
![Page 20: Sep 7: Animal behavior (Ch 51). Dispatch 9/7 1) What is the difference between NPP and GPP? 2) How are cellular respiration and photosynthesis similar?](https://reader035.vdocument.in/reader035/viewer/2022062309/5697c0251a28abf838cd5285/html5/thumbnails/20.jpg)
Many behaviors have a strong genetic component
• Biologists study the ways both genes and the environment– Influence the development of behavioral
phenotypes• Behavior that is developmentally fixed– Is called innate behavior and is under strong genetic
influence
![Page 21: Sep 7: Animal behavior (Ch 51). Dispatch 9/7 1) What is the difference between NPP and GPP? 2) How are cellular respiration and photosynthesis similar?](https://reader035.vdocument.in/reader035/viewer/2022062309/5697c0251a28abf838cd5285/html5/thumbnails/21.jpg)
Behavior 3: Directed Movements (Kinesis and Taxis)
• Many animal movements– Are under substantial genetic influence
• These types of movements– Are called directed movements
• 1) A kinesis– Is a simple change in activity or turning rate in response
to a stimulus• 2) A taxis– Is a more or less automatic, oriented movement toward
or away from a stimulus
![Page 22: Sep 7: Animal behavior (Ch 51). Dispatch 9/7 1) What is the difference between NPP and GPP? 2) How are cellular respiration and photosynthesis similar?](https://reader035.vdocument.in/reader035/viewer/2022062309/5697c0251a28abf838cd5285/html5/thumbnails/22.jpg)
• Many stream fish exhibit positive rheotaxis– Where they automatically swim in an upstream
direction

(b) Positive rheotaxis keeps trout facing into the current, the direction from which most food comes.

Behavior 4: Animal Signals and Communication
• In behavioral ecology– A signal is a behavior that causes a change in another animal’s
behavior• Communication
– Is the reception of and response to signals
• Animals communicate using– Visual, auditory, chemical, tactile, and electrical signals
• The type of signal used to transmit information– Is closely related to an animal’s lifestyle and environment
![Page 24: Sep 7: Animal behavior (Ch 51). Dispatch 9/7 1) What is the difference between NPP and GPP? 2) How are cellular respiration and photosynthesis similar?](https://reader035.vdocument.in/reader035/viewer/2022062309/5697c0251a28abf838cd5285/html5/thumbnails/24.jpg)
Behavior 5: Learning
Learning is the modification of behavior– Based on specific experiences
• Learned behaviors– Range from very simple to very complex
![Page 25: Sep 7: Animal behavior (Ch 51). Dispatch 9/7 1) What is the difference between NPP and GPP? 2) How are cellular respiration and photosynthesis similar?](https://reader035.vdocument.in/reader035/viewer/2022062309/5697c0251a28abf838cd5285/html5/thumbnails/25.jpg)
Spatial and Associative Learning
• Spatial learning is the modification of behavior–Based on experience with the spatial structure of
the environment
• In associative learning–Animals associate one feature of their
environment with another–Operant conditioning is another type of associative
learning In which an animal learns to associate one of its behaviors with a reward or punishment
![Page 26: Sep 7: Animal behavior (Ch 51). Dispatch 9/7 1) What is the difference between NPP and GPP? 2) How are cellular respiration and photosynthesis similar?](https://reader035.vdocument.in/reader035/viewer/2022062309/5697c0251a28abf838cd5285/html5/thumbnails/26.jpg)
Behavior 6: Classic Conditioning• Classical conditioning is a type of associative
learning– In which an arbitrary stimulus is associated with a
reward or punishment

Behavior 7: Cognition and Problem Solving
• Cognition is the ability of an animal’s nervous system– To perceive, store, process, and use information
gathered by sensory receptors
• Problem solving can be learned– By observing the behavior of other animals
Figure 51.17
