Study Notes

Mating Systems

Monogamous relationships involve one male mating with one female.
Polygyny is when one male mates with multiple females.
Polyandry is when one female mates with multiple males

Parental Care

The needs of offspring are a key factor in the evolution of mating systems.
The certainty of paternity can affect parental care, as well as mating behavior.
In species with large offspring, parental care is more likely to be shared between males and females.

Sexual Selection

In intersexual selection, members of one sex select mates based on certain characteristics.
In Intrasexual selection, members of the same sex compete for mates.

Mate Choice by Females

Male zebra finches are often more ornate than females, which might influence female mate choice.

Environmental Influences

The type of food eaten during larval development can influence mate choice in females.

Animal Cognition

A cognitive map is an internal representation of spatial relationships in an animal's environment.

Associative Learning

Associative learning occurs when animals associate one feature with another in their environments.
Classical conditioning is a type of associative learning in which a stimulus is associated with a reward or punishment.
Operant conditioning is a type of associative learning in which a behavior is associated with a reward or punishment.

Cognition and Problem Solving

Cognition involves the ability to perceive, store, process and use information gathered through sensory receptors.

Altruism

Kin selection is a type of altruistic behavior that benefits relatives.
Reciprocal altruism is a type of altruistic behavior towards unrelated individuals, which can be adaptive if a reciprocal favor is likely in the future.

Social learning is the basis for cultural development.
Culture is defined as a system of information transfer, through observation or teaching, that influences behavior in a population.

Mate Choice Copying

Mate choice copying occurs when individuals copy the mate choices of others.
This behavior has been studied in the guppy, where females prefer males with certain characteristics.

Vervet monkeys produce a complex set of alarm calls.
Infant verver monkeys learn to fine-tune their alarm calls over time.
