| Semelparous | (SALMONPAROUS) Lots of investment put in, usually die after reproduction. Examples: Salmon, crops |
| Iteroparous | Many reproductive events, investment split between multiple offspring. Examples: humans, mice, ants |
| Principle of Allocation | The distribution of energy between traits. Example: Size vs. Number of offspring. The bigger one variable is the smaller the other one must be |
| Continuous Reproduction | Continuously reproducing, always at it. Exponential Growth. Example: Humans |
| Discrete Reproduction | Discrete breeding seasons, only reproducing for part of the year. Geometric Growth. Example: Sheep |
| Define K | Carrying Capacity. (The maximum number of species a habitat can contain without using up all the resources) |
| R-Selected Species | HIGH RATE OF INCREASE Early maturity Small body size High reproductive output Example: Pests |
| K-Selected Species | LOW RATE OF INCREASE Low maturity Large body size Low reproductive output Have very stable populations Example: Whales |
| What is important to note about K- and R- Selected Species? | Continuum over binary split. Organisms sometimes show/share traits of both |
| Define Life History | Life History concerns Growth... Reproduction... Survival... |
| Traits | Traits are Body size at maturity Reproductive output and frequency Life span |
