1. Population Ecology

2. Population A group of individuals of a single species in a given area
Density
Dispersion

3. Clumped

4. Uniform

5. Random

6. Demography
The study of statistics that affect population size

7. Life Table

8. Survivorship Curve

9. Reproductive Table

10. Life Histories
Semelparity
Iteroparity

11. Population Growth Exponential Growth dN/dt = rmaxN
dN = change in number
dt = change in time
rmax = intrinsic growth rate
N = number of ind.

12. Population Growth Logistic Growth dN/dt = rmaxN (K-N) K
dN = change in number
dt = change in time
rmax = intrinsic growth rate
N = number of ind.
K = Carrying Capacity

13. Logistic Growth

14. Life Histories r selected K selected Large number of offspring
No parental care
Small in size
Short lifespan
K selected
Small number of offspring
Large amounts of parental care
Large in size
Longer lifespan

15. Population Limiting Factors
Density Independent
Natural disasters
Density Dependent
Disease

16. Human Population and ZPG
Which type of growth do humans follow?
What is ZPG?
