AP Bio Chapter 51 Part 3 Flashcards
What’s the relationship between behavior and genetics
The ability to learn
In ecology, what relationships do biologists investigate
Behavior and genetics
Behavior and the environment
Behavior and fitness
Behavior and altruism
Ex. 1 insect calls
When morphologically identical green lacewings are hybridized, what is the result
They have songs that have combined characteristics of both paternal species
Ex. 2 migration
When young blackcap birds were captured in Britain and raised in Germany what happened
The birds demonstrated a migratory preference different from German blackcaps
What is behavior’s relationship with the environment
Environmental constraints determine fitness which includes behavior
Foraging
Food obtaining behavior
Example 1. Natural selection should favor what? (What is the optimal foraging theory)
Minimized energetic cost and maximized food acquisition
Example 2. Parental influence SEE GRAPH
Learned behavior’s have to be taught
What’s the relationship between behavior and fitness
Behavior should increase reproductive success
Mating systems
The mating system has an effect on sexual dimorphism on a species
What are the three types of sexually reproducing species
Monogamous species-one partner for life
Polygynous species-where one male has many partners
Polyandruous-where one female has many partners
Parental care
Parental care is influenced by the certainty of paternity
Sexual selection
Mate preference of females can drive the evolution of male behavior
Agnostic behavior
Male competition for mates can have similar effects
Game theory
A field of “behavioral economics” which evaluates the advantages of different strategies
Ex of game theory applicants, describe the applicants (side blotched lizards)
Orange throat-most agrresuve, largest territory
Blue throat-less aggressive, smaller territory
Yellow threat-non territorial, sneaky mater
O>B B>Y Y>O
Altruism
Refers to any behavior that an organism engages in which increases the fitness of other organisms while decreasing its own fitness
What is altruism explained
Relatedness. Altruism evolves in populations of closely related individuals
Inclusive fitness
Anything that increases of an organism’s genes (not necessarily by the organism)
