Simulation with real dumpster
Consequences
on population
dynamics
Main cause of death: collisions + diseases
High density at dumpster
Disease spread in simulation
Dumpster increases local contamination
Dumpster increases infection risk
Are dumpster raccoons different?
Age effect in trapping success
Junk food and obesity?
Conclusions
- Clear human impact at fine scale
- Smaller home ranges
- Higher disease prevalence
- Impact on fitness?
