The Answers Are Blowin’ in the Wind
Southern Crawfish Frogs appear to be the only subspecies in Texas and Louisiana, while Northern Crawfish Frogs appear to be the only subspecies in Kansas, Missouri, Iowa, Illinois, Indiana, Kentucky, Tennessee, and Alabama. The impression is that Southern Crawfish Frogs in southern Oklahoma, for example, evolved into Northern Crawfish Frogs in northern Oklahoma, and Southern Crawfish Frogs in eastern Louisiana evolved into Northern Crawfish Frogs in Alabama. As Bragg observed, Crawfish Frog egg deposition sites tend to be clustered around calling sites. Chelsea Kross has been working on several aspects of Crawfish Frog population biology for her doctorate in the Department of Biological Sciences at the University of Arkansas Fayetteville. This information on Arkansas Crawfish Frog populations will be novel, and may help fill in gaps between our population, located at the extreme northeastern portion of the species’ distribution, and the Attwater population, representing the extreme southwestern corner of the species’ distribution.
