- 2. Why have reptiles been stable? • Is it due to where they live now?
- 3. Why have reptiles been stable? • Is it due to where they live now? • Is it due to where they lived in the past i.e. the location of their refugia?
- 4. Why have reptiles been stable? • Is it due to where they live now? • Is it due to where they lived in the past i.e. the location of their refugia? • What life history traits do the stable reptiles have in common?
- 5. Why have reptiles been stable? Is it due to where they live now?
- 6. Why have reptiles been stable? Wet tropics Is it due to where they live now? Southeast Semi-arid
- 7. Why have reptiles been stable? Wet tropics Frogs also live in high numbers in the wet tropics and Victoria Southeast
- 8. Why have reptiles been stable? Birds also live in relatively high numbers in the semi-arid Semi-arid
- 9. Why have reptiles been stable? Is it due to refugia in the past?
- 10. Why have reptiles been stable? Is it due to refugia in the past? Hotspot in reptile diversity = refugium
- 11. What do the species have in common? Stable reptile life history traits
- 12. Stable reptile life history traits • Smaller body size
- 13. • Smaller body size • Smaller range size Stable reptile life history traits
