Presentation Transcript

  1. Serengeti Wildebeest: Density-dependent population growth

  2. Rainfall (mm) Month

  3. RPV

  4. Rinderpest Virus 1889 – Italian army makes a big mistake 1897 – 5 million cattle and 30 million wild ungulates have died

  5. Large cattle population

  6. RPV is a morbilivirus that only affects ruminants

  7. Overall growth rate, differentiated form Population size, integrated form

  8. Carrying Capacity K = 1.2M

  9. K = fn(Rain) Fit to data so that mean K = 1.2M

  10. Verhulst-Pearl Model - Logistic population growth - Density dependent population growth - Intraspecific competition for resources 1838 Model 1926 Application to human population data 1. Examine some details of P-V model of DD growth. 2. Comparison to OTHER models of DD growth
