About This Chapter
Overview of Animal Behavior - Chapter Summary
In this chapter, our instructors explain the factors that contribute to animal behavior and how these interact with one another. You will find out about innate behavior including reflexes, kineses, and taxes, all of which are responses to stimuli. You will be introduced to the concept of learned behavior, including imprinting, where a newborn animal forms an attachment to the first object it sees after birth, usually, its mother, as well as habituation and conditioning.
As the chapter continues, you'll find out about social behavior including the cost-benefit of altruism and kin selection, as well as agonistic behaviors, dominance hierarchies and territoriality. You'll find out about the relationship between social systems and individual fitness. After completing this chapter, you should be able to:
- Define innate behavior and give examples of different types
- Explain types of learned behavior
- Discuss social behavior including altruism, dominance hierarchies and territoriality
- Distinguish social systems from individual fitness
- Define the theory of demographic transition
Our approach revolves around brief, engaging video lessons that make learning fun. Along with the videos come self-assessment quizzes to check your comprehension of the material as well as written transcripts you can refer to for further review. We highlight the important concepts via key terms in bold. Plus, we make it super easy to review sections of the videos by giving you video tags that take you right to the spot you are looking for. These materials have all been developed by our expert instructors.
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.
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.
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.
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.
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.
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.
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.
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.
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.
