Young, small, sexually-inexperienced males suffer lower mating success than older, larger, more experienced males in many species of animals. I compared the mating success of male Desmognathus ochrophaeus (Amphibia: Caudata: Plethodontidae) reared to

Intrinsic constraints resulting in temporally-limited mating capacity may select for ‘prudence’ in the allocation of sexual resources by male salamanders. Prudence in the form of male mate choice was examined in a dusky salamander, Desmognathus s

Only males provide parental care in midwife toads (genus Alytes), carrying fertilized eggs entwined around the hind limbs. Although energetic investment in reproduction probably is greater for females, male care may be a limited resource in terms of

We provide the first description of courtship behavior in the North American salamander Desmognathus santeetlab Tilley from the Great Smoky Mountains. As appears typical for the genus, the courtship of D. santeetlab is comprised of three phases : ori

Sexual isolation between two species of North American plethodontid salamanders (Desmognathus imitator and D. ochrophaeus) from a locality where they are sympatric was investigated by staging a series of 40 intraspecific and 40 interspecific sexual e

and Summary 1 When a male smooth newt encounters a ♀ who is already engaged in courtship, he may mimic her behaviour during the spermatophore deposition and transfer stages of the courtship. He thereby usurps the courting ♂ and may inseminate the

We constructed a model for the evolution of sexual isolation by extending Lande's (1981) model of sexual selection. The model predicts that asymmetric sexual isolation is a transient phenomenon, characteristic of intermediate stages of divergence in

The courtship behaviour of the North American southern dusky salamander, Desmognathus fuscus conanti (Plethodontidae), is described for the first time. The male is the most active participant, as is typical for caudate amphibians, and much of his beh

Reproductive interactions among species in areas of sympatry and contact zones have long fascinated evolutionary biologists. Much interest and fierce debate has centered on the potential for natural selection to prevent interspecific mating between s
