Author Information

Primary Institution: Iowa State University
Hypothesis
How do thermal fluctuations affect sex ratios in turtles with temperature-dependent sex determination?
Conclusion
Increased thermal variance around both low and high temperatures reversed the expected sex ratios in painted turtles.
Supporting Evidence
- Thermal fluctuations reversed turtle sex ratios from those expected by the mean temperature.
- Mortality rates were significantly higher under certain temperature treatments.
- Results were consistent across multiple years of experimentation.
Takeaway
When temperatures change a lot, it can change how many boy and girl turtles are born, which is important for their survival.
Methodology
Eggs of painted turtles were incubated at varying temperatures to observe the effects on sex ratios.
Potential Biases
Potential biases in the experimental setup could affect the generalizability of the results.
Limitations
The study's findings may not apply to all turtle species or natural conditions.
Participant Demographics
The study focused on painted turtles (Chrysemys picta).
