Ch 34: Animal Behavior

About This Chapter

Watch online video lessons to learn about kin selection, circadian rhythms, fixed action patterns and more. Each lesson is accompanied by a short multiple-choice quiz to help check your understanding of these animal behavior topics.

Animal Behavior - Chapter Summary and Learning Objectives

The lessons included in this chapter can help you distinguish between behaviors used to respond to stimuli and behaviors that are essential for establishing social relationships and group identity. Instructors also discuss animal communication techniques and population dynamics. By the end of this chapter, you should be familiar with the following:

  • Differences between innate and learned behaviors
  • Benefits of social systems and groups
  • Types of behavior affecting social group interaction
  • Relationship between population demographics and ecosystem health

Video Objective
Innate Behavior: Reflexes, Kineses and Taxes Describes the differences between reflexes, kineses and taxes, as well as fixed action patterns, migration, stereotypy and circadian rhythms
Learned Behavior: Imprinting, Habituation and Conditioning Provides examples of classical and operant conditioning and explains how habituation, insight and imprinting help us learn new behaviors
Social Behavior: The Cost-Benefit of Altruism and Kin Selection Contrasts altruistic, cooperative, selfish and spiteful behaviors before comparing the costs and benefits of living in groups
Social Behavior: Agonistic, Dominance Hierarchies and Territoriality Explains the effects of aggressive behaviors, ranking hierarchies and the competition for space in social interactions
Social Systems vs. Individual Fitness: The Queen/Worker Relationship Shows how social systems improve the inclusive fitness of a group, sometimes at the expense of individual fitness
The Theory of Demographic Transition: Overview Identifies the five stages of this population change model and describes demographic terms, including mortality rate and life expectancy
Carrying Capacity of a Population: Effect of Biomedical Progress Explains how advances in medicine and technology affect our ecosystem's maximum occupancy
The Circadian Rhythm Discusses the benefits of an organism's ability to successfully transition between states of sleep and wakefulness
How Animals Communicate: Chemical, Visual and Electrical Signals Describes the use of pheromones, allomones, visual displays and electric signals
Biological Influences on Human Behavior: Genetics & Environment Explores the ways in which genetics and the environment impact human behavior.

Innate Behavior: Reflexes, Kineses and Taxes

1. Innate Behavior: Reflexes, Kineses and Taxes

When there is a loud sound, you quickly jump without thinking. This is because this reflex is an innate, or inherited, behavior. In this lesson, we will look at reflexes as well as several other types of innate behaviors.

Learned Behavior: Imprinting, Habituation and Conditioning

2. Learned Behavior: Imprinting, Habituation and Conditioning

Ever wonder why it is easier to train your dog when you give him a treat every time he does something correct? In this lesson we will take a look at conditioning as well as several other forms of learned behavior.

Social Behavior: The Cost-Benefit of Altruism and Kin Selection

3. Social Behavior: The Cost-Benefit of Altruism and Kin Selection

Ever wonder why people are more likely to help their relatives than complete strangers? Social behavior can help explain this and other actions. Let's look at the cost of certain behaviors.

Social Behavior: Agonistic, Dominance Hierarchies, & Territoriality

4. Social Behavior: Agonistic, Dominance Hierarchies, & Territoriality

Instead of using words, animals communicate with each other through social behaviors. These actions between individuals may be used to establish rank, defend home and breeding sites, and compete for resources.

Social Systems vs. Individual Fitness: The Queen/Worker Relationship

5. Social Systems vs. Individual Fitness: The Queen/Worker Relationship

The queen bee rules her hive while others take care of her needs. This form of behavior may seem odd, but it can be explained by looking into social systems and fitness.

The Theory of Demographic Transition: Overview

6. The Theory of Demographic Transition: Overview

Populations change over time. The growth or decline of a population can have an effect on the quality of life for people within that population. In this lesson, you'll learn about the theory of demographic transition, which is a model used to study and predict population changes.

Carrying Capacity of a Population: Effect of Biomedical Progress

7. Carrying Capacity of a Population: Effect of Biomedical Progress

The human population continues to grow. There are several things that contribute to this growth, including biomedical progress. In this lesson, we will look at some examples as well as what may happen if this growth continues.

The Circadian Rhythm

8. The Circadian Rhythm

You wake up in the morning and go to sleep at night. But some animals do the opposite: wake at night and sleep during the day. What determines the time of day you're active is your circadian rhythm, an internal clock that keeps daily time for you.

How Animals Communicate: Chemical, Visual & Electrical Signals

9. How Animals Communicate: Chemical, Visual & Electrical Signals

Animals use a variety of different signals to communicate with each other. In this lesson you'll identify the different types of communication signals and the situations in which they might be most useful.

Biological Influences on Human Behavior: Genetics & Environment

10. Biological Influences on Human Behavior: Genetics & Environment

Humans are a product of both our genetic makeup and our environmental surroundings. Does one influence our behavior more than the other? It can be difficult to tell, but there are ways that scientists can better understand why we do the things we do.
