Animal Behavior Mrs. Rightler
Methods of Study Comparative psychology Ethology Behavioral ecology Sociobiology
Instinct Basic set of behaviors present at birth May need a trigger Behavior improves or changes with experience
Maturation Behavior seen after a period of development has occurred Improvement or change not based on experience but on time Ex. Tadpole swimming techniques
Imprinting Konrad Lorenz Critical time period ONLY Young animal develops attachment to another animal or object Rapid learning
Habituation Animal trained to ignore stimuli Dog examples
Classical Conditioning Pavlov’s dog Animal learns to respond to particular stimuli Basic obedience training
Instrumental Conditioning Trial-and-error learning Skinner Box Behavior can be “shaped”
Latent Learning Exploratory learning No obvious reward Helps animal learn about its surroundings
Insight Learning Animal uses experiences and thinking to solve problems. Tool use Primates
Behavior is Controlled by: Nervous system Endocrine system – Organizational effects – Activational effects
Animal Communication Transfer of information from one animal to the other (both must be mutually adapted) Visual Auditory Tacticle Chemical
Habitat Selection Two factors influence habitat choice – Physiological – Psychological
Foraging Behavior Process of locating food resources Cost vs. benefit analysis – Handling time – Nutritional value – Status value – Concentration/density
Specialists vs. Generalist
Social Behavior Members of the same species Usually live full-time in groups Can refer to predator-prey interactions
Group Living Animal society – stable group of individuals of the same species that have cooperative relationships outside of mating and raising young. Invertebrates and vertebrates
Advantages to Group Life Protection from predators Increase feeding efficiency Protection from elements Easy access to potential mates
Disadvantages of Group Life Competition for resources Diseases Parasites
Aggression Agonistic behavior Attacks Threat displays Maintains territory Maintains dominance hierarchy
Altruism Individual sacrifices reproductive potential for the benefit of others in the group – Honeybees – Turkeys – Naked mole rats Kin selection
Animal Behavior Mrs. Rightler. Methods of Study Comparative psychology Ethology Behavioral ecology Sociobiology.
Social Behavior Members of the same species Usually live full-time in groups Can refer to predator-prey interactions.
Animal Interactions Responses to the biotic environment.
Chapter 51 Reading Quiz 1.What an animal does and how it does it is known as ____. 2.From what 2 main sources is behavior derived? 3.The full set of food-obtaining.
Adaptive Behavioral Responses
Animal Behavior. Behavior BEHAVIOR -The way an organism responds to changes in its internal and external environment. IS ESSENTIAL FOR A SPECIES SURVIVAL.
Chapter 34 Animal Behavior
Behavioral responses to stimuli may be adaptive.
Animal Behavior Chapter 51. Behavior Animal responds to stimuli Food odor Singing.
Behavioral Ecology Chapter 37. Nature vs. Nurture Behavior To what degree do our genes (nature) and environmental influences (nurture) affect behavior?
Ethology = the study of animal behavior Behavior = a response to a stimulus.
Animal Behavior Male Jumping Spider (Habronattus icenoglei)
ANIMAL BEHAVIOR. Behavior Behavior can occur in response to an internal or external stimulus. Study of behavior and its relationship to evolutionary.
Animal Behavior Chapter 34 /. What is a behavior? Any response to a stimulus (an external signal) Examples of stimuli Sounds Smells Sights (light vs dark)
Animal Behavior Ecology Unit.
Behavioral Biology Chapter 55
Animal Behavior CVHS Chapter 51. Behavior What an animal does and how it does it Proximate causation – “how” –environmental stimuli, genetics, anatomy.
Animal Behavior. Adaptive Behavioral Responses Stimulus – Stimulus – –Internal stimuli tell an animal what is happening in its own body Ex. Thirst, hunger,
Social Interactions Animal Behaviors. Behavioral Controls Genetic: Instincts, hormonal controls. Learned: Imprinting, classical and operant conditioning,
Biology 105 Animal Behavior Pgs Animal Behavior Pgs
1 Approaches to the Study of Behavior __________can be defined as the way an organism responds to stimuli in its environment. Is behavior learned or genetic?
Animal Behavior. Behavior Behavior is what an animal does and how it does it Behavior is a result of GENETIC and ENVIRONMENTAL factors (nature vs nurture)
Living in groups also has benefits and costs.
Animal Behavior Chapter 51.
Behavioral Biology Chapter 51.
CHAPTER 20: BEHAVIOR, SELECTION, & SURVIVAL. Anthropomorphism – when humans reflect their emotions on to animals Behavior the way an organism acts What.
Animal Behavior Behavior is what an animal does and how it does it.
Animal Behavior Ethology.
Animal behavior How do we study it? How do we classify it?
UNIT 10 Animal Behavior. Introduction Humans have always studied animal behavior Knowledge of animal behavior = human survival For example, understanding.
Animal Behavior Biology 155 A. Russo-Neustadt. I. Definition: Behavior is the observable response that an animal makes to a stimulus. Responses can have.
Ethology: The study of animal behavior with emphasis on the behavioral patterns that occur in natural environments.
Behavioral Ecology Behavior-what an animal does and how it does it
Animal Behavior Archer fish and acorn woodpeckers.
Behavior in living organisms Behavior in one celled organisms Behavior in plants Behavior in animals.
Animal Behavior Behavior What an animal does and how it does it Influenced by genes and environment (“nature and nurture”) Proximate and ultimate.
Instinct inborn, unlearned behavior Triggered by releasers – Ex. male Robins Inherited circuitry Fixed action pattern – not simple reflexes, not.
Chapter 50 Animal Behavior.
Chapter 51 ~ Behavioral Biology. Behavior l Ethology ~ study of animal behavior l Causation: proximate ~ physiological & genetic mechanisms of behavior.
Animal Behavior. Behavior is the way an organism reacts to changes in its internal condition or external environment. A stimulus is any kind of signal.
Behavior Chapter 51 (50).
Chapter 31 Animal Behavior
Animal Behavior. What’s going on? Sensation Perception Stimulus.
AP Biology Animal Behavior AP Biology What is behavior & Why study it? Behavior everything an animal does & how it does it response to.
