Hypothesis
Does urbanization affect adult survival in the Cuban lizard Anolis homolechis?
Conclusion
The study found no significant evidence that urbanization leads to different survival rates based on body size in Anolis homolechis.
Supporting Evidence
- Adult survival did not differ between suburban and forest habitats.
- Significant stabilizing selection on female size was observed.
- Male survival was independent of body size.
Takeaway
This study looked at how Cuban lizards survive in cities compared to forests and found that being bigger doesn't help them survive better in urban areas.
Methodology
The study used a 20-month capture-mark-recapture survey to assess adult survival in two suburban and two forest populations of Anolis homolechis.
Potential Biases
Potential biases may arise from variations in capture methods and the number of people involved in the data collection.
Limitations
The study could not differentiate survival from permanent emigration, which may affect the accuracy of survival estimates.
Participant Demographics
The study involved capturing and marking 735 adult lizards, with 435 males and 300 females.
