Evol Eco

Question 1

The tragedy of commons

Answer 1

The situation in which multiple individuals, acting independently and rationally consulting their own self-interest, acts against the common interests of the group

Does not involve coordination
E.g communism

Question 2

Coordination games

Answer 2

Games in which all parties can realise mutual gains, but only by making mutually consistent decisions

Question 3

Game Theory

Answer 3

Is a mathematical theory of strategic decision making

Evolutionary game theory adds to the classical game theory rules of the faster reproduction rates of not successful strategies

Question 4

Evolutionary stable strategy

Answer 4

Is a Nash equilibrium which is Evolutionary stable ie once it is fixed within the population, natural selection alone is sufficient to prevent alternative (mutant) strategies from successfully invading

Question 5

Nash equilibrium

Answer 5

A set of strategies is a Nash equilibrium if no player can do better by unilaterally changing his strategy

Question 6

The prisoners dilemma game

Answer 6

Describes only one type of situations demanding strategic decisions; changing the balance of playoffs may create conditions more beneficial for collaboration

These conditions are best described by snow drift, hawk-dove and party-Home

Question 7

Latitudinal diversity gradient (LDG)

Answer 7

Is the increase in species richness or biodiversity that occurs from the poles to the tropics

Question 8

Sexual reproduction

Answer 8

the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female).

Question 9

Disparity

Answer 9

The amount of biological shape variety, this is the range of observed morphological variation

Question 10

Diversity

Answer 10

The variability among living organisms

Question 11

Macroevolution

Answer 11

Major evolutionary change, especially within regards to the evol or whole taxonomic groups over long periods of time (long time scales with large groups)
