2. Topics  Community Relations  Competition  Modeling Competition  Case Study: SARS

3. Community Relations  Community – Interaction between species  Ecological Niche – Role that species plays in an ecosystem  Predator-prey

4. Competition  Everyday life  Intraspecific  Interspecific  Exploitative or Resource Depletion  Interference

6. Spread of SARS  SIR model  Susceptibles  Infecteds  Recovereds

7. SARS Relationships  Susceptible: do not have but can catch SARS  Susceptible_quarantined: do not have, quarantined because of exposure, cannot catch SARS  Exposed: have SARS, no symptoms, not yet infectious  Exposed_quarantined: have SARS, no symptoms, not yet infectious, quarantined  Infectious_undetected  Infectious_quarantined  SARS_death  Recovered_immune: recovered, immune to further infection
