Unisexual Ambystoma salamanders are generally polyploid and contain genomes from multiple "true" sexual species. Does this give them any measurable functional advantages? In order to begin addressing this question, Gary Gerald and Katy Greenwald are running treadmill and racetrack trials to measure endurance and top speed, respectively. This research is in its preliminary stages, but the videos are too funny not to share. Big thanks to Bob Brodman, who raised another group of juveniles for us to test this year.

"We should figure out a way to embed a video on Ambystoma.net." Done!
