Question 1

Dispersion patterns

Answer 1

Clumped
Random
Uniform

Question 2

Survivorship curves? Types?

Answer 2

Plot survivorship as the proportion of individuals from an initial population
Type 1- few offspring, good care
Type 2- constant
Type 3- lots of offspring, not good care

Question 3

Exponential growth model

Answer 3

Gives an idealized picture of unlimited population growth, no restrictions on the abilities of the organisms to grow, live and reproduce, populations will all eventually be limited by the resources available

Question 4

Logistic growth model

A description of idealized population growth that is slowed by limiting factors as the population size increases

Trade offs- balance demands of reproduction and survival
R-selection - try to maximize # of individuals (brute force reproduction)
K-selection - better off having less offspring and investing more time in each
