Behavior

What is Behavior?
Behaviors are actions that an animal engages in—whether it is related to finding food, reproducing, defending against threats, or any number of…
Imprinting
26.2: Imprinting
Imprinting is the irreversible process by which some newborn animals learn to recognize their parents, and vice versa, creating a strong bond.…
Communication
26.3: Communication
Communication is simply defined as the process of transmitting and receiving signals. Organisms communicate with one another in a host of different…
Migration
26.4: Migration
Migration is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. It…
Mate Choice
26.5: Mate Choice
Mate choice—the decision about who to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. It…
Fixed Action Patterns
26.6: Fixed Action Patterns
A fixed action pattern (FAP) is a specific, hard-wired, sequence of behavior that occurs in response to an external stimulus, called a sign stimulus.…
Optimal Foraging
26.7: Optimal Foraging
The way in which animals obtain and eat their food is called foraging behavior. It can include searching for plants and hunting for prey, depending…
Parental Care
26.8: Parental Care
Many animals exhibit parental care behavior, which includes the feeding, grooming, and protection of young offspring. Parental care is particularly…
Altruism
26.9: Altruism
Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the animal carrying out the…
Inclusive Fitness
26.10: Inclusive Fitness
Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these…
Social Stress
26.11: Social Stress
The Resident-Intruder task is a well-established paradigm for modeling social stress in rodents. The task utilizes a naturalistic behavioral response…
Spatial Navigation
26.12: Spatial Navigation
Behavioral researchers examine spatial learning and memory in rodents by manipulating the organism's surroundings with the help of mazes, like…
Behavior: Using a Virtual Store as a Research Tool to Investigate Consumer In-store Behavior
26.13: Behavior: Using a Virtual Store as a Research Tool to Investigate Consumer In-store Behavior
There are various approaches to study consumer buying, but they don’t resemble realistic experiences. This protocol uses a virtual store…
Biology: Measuring the Effects of Bacteria on C. Elegans Behavior Using an Egg Retention Assay
26.14: Biology: Measuring the Effects of Bacteria on C. Elegans Behavior Using an Egg Retention Assay
Under natural conditions, when C. elegans come in contact with potentially harmful bacteria, they will retain their eggs until they find a safer…
Neuroscience: Tracking Drosophila Larval Behavior
26.15: Neuroscience: Tracking Drosophila Larval Behavior
How insects navigate towards odors using olfactory receptor neurons is not well understood and replicating conditions that activate them is…
