Salamander courtship coordinates the exchange of gametes. Plethodontids
have evolved an elaborate means by which this is done. Throughout the family
Plethodontidae a tail-straddling walk is performed to orchestrate the transfer of sperm.
Typically this behavior is linear, however in the genus Aneides there are exceptions.
In the genus Aneides there are two species that have a circular tail-straddling
walk; others perform the highly conserved linear tail-straddling walk. I observed
courtship in three species of Aneides and used accounts of others to discern which
members possessed circular tail-straddling walk and used a phylogeny to map the
courtship characters found in the courtships of the members of the tribe plethodontini. / Graduation date: 2003
