Hypothesis

How do morphological characters in Gryllus fultoni differ between sympatric and allopatric populations?

Conclusion

The study suggests that reproductive character displacement influences morphological traits in Gryllus fultoni, particularly in areas where it coexists with Gryllus vernalis.

Supporting Evidence

  • Morphological characters in Gryllus fultoni showed significant differences between sympatric and allopatric populations.
  • Head width and hind femur length were more similar to Gryllus vernalis in sympatric populations.
  • Mirror area displayed a divergent pattern in relation to Gryllus vernalis populations.

Takeaway

This study looks at how two types of crickets change their body shapes when they live together compared to when they live apart, helping them not to mix with each other.

Methodology

The study measured various morphological characters of Gryllus fultoni and Gryllus vernalis in sympatric and allopatric populations using multivariate general linear models.

Limitations

The study primarily focused on morphological traits and did not explore all potential factors influencing reproductive isolation.
