1. Serengeti Wildebeest: Density-dependent population growth
2. MonthRainfall (mm)
3.
4. Dry season vegetation type = long grass & open woodland
5. Wet season vegetation type = short grass plains (productivity, nutrients)
6. Synchronized birth pulse, precocial offspring
7. RPV
8. 1889 – Italian army makes a big mistake1897 – 5 million cattle and 30 million wild ungulates have diedRinderpest Virus
9. Large cattle population
10. RPV is a morbilivirus that only affects ruminants
11.
12. Overall population growth rate, differentiated formPopulation size, integrated form
13. Carrying CapacityK = 1.2M
14. K = fn(Rain)Fit to data so thatmean K = 1.2M
