- When will individuals form groups?
- What happens when many individuals exploit the same limited resources?
- The decisions made by one competitor may influence what others are doing
- In some cases this can lead to defence of resources
- Females come to dung to lay their eggs.
- Males wait on the dung for females, copulate with them, then guard them.
- Females need fresh dung as old dung gets a crust on top.
- How long should males wait for females?
- Competition - if other males stay for a short time it pays to stay longer (no competition) but if other males stay for a long time it pays to move to new dung.
How long to stay?
- 2 habitats:
- Rich habitat
- Poor habitat
- Each individual exploits the habitat that gives it the most rewards
- Imagine no resource defence
- What will the first arrivals do?
- What will the last arrivals do?
- A point will be reached where the nest arrivals will do better to occupy the poorer qwuality habitat.
- Less resources
- But, less competition
- Eventually, the two habitats will be filled so the profitability is the same in each one.
- Profitability is the same for all individuals
