*Which dispersion pattern is the most common in nature?*
|
CLUMPED because species are somewhat social for protection
|
|
|
Population Dispersion: Three Types
|
1) Clumped: together in patches
2) Uniform: Equal spacing 3) Random: No pattern |
|
|
Life Table:
|
Age-Specific Summary of the survival of individuals in a population:
Type 1: High Survivorship through early and middle ages Type 2: Relatively constant survivorship throughout life Type 3: Low survivorship early in life |
|
|
Fertility/Fecundity:
|
Age-Specific summary of the reproductive rates in a population
|
|
|
Life History:
|
The traits that affect an organism's schedule of survival and reproduction
|
|
|
Parity Types:
|
- Semelparity: Large numbers of offspring produced in a single reproductive effort
- Interoparity: Small numbers of offspring produced in each of several reproductive efforts |
|
|
Two Extremes in Life History Strategies:
|
r-selected species: Rapid growth and reproduction... unpredictable environments
k-selected species: Slow growth and reproduction... Many, small offspring. |
|
|
Logistic Population Growth:
|
Population growth is limited by carrying capacity
