- disease dynamics
- metapopulation
2
Q
Abiotic external factors example
A
Warm winter weather associated with pop declines in alpine butterflies
3
Q
Scramble competition
A
Populations can fluctuate all by themselves in constant environment
4
Q
Predator-prey interactions
A
Predator cycle lags behind prey
5
Q
Disease dynamics: Herd immunity
A
for diseases with lasting immunity
6
Q
Metapopulation
A
local extinctions and (re-)colonisations
patches become occupied and inactive in cycles
