“…We also recorded the latency between the introduction of the female into the male’s home enclosure and the male’s first attempt to bite the female’s tail, hereafter referred to as latency to tail grab. Tail grabbing and biting is a typical component of courtship in this species (Brillet 1991). We used latency to tail grab as an indicator of a male’s motivation to mate; higher latencies reflected a lower motivation to copulate (LaDage & Ferkin 2006, 2007).…”

Females across many taxa may mate with several males or mate more than once with the same male within one reproductive event. Although many researchers have discussed the effects of multiple mating on reproductive success of females, few studies have attempted to disentangle whether the reproductive success of females differs with respect to whether females mate with multiple males or mate more than once with one male. In this study, we hypothesized that female leopard geckos (Eublepharis macularius) increase aspects of their reproductive success, such as fecundity, fertility and relative clutch mass, by mating more than once within one reproductive event, either by mating repeatedly with the same male or multiply mating with different males. We controlled for the potentially confounding variables of mating frequency and mate number by allowing females to mate once with one male, twice with the same male, or twice with two different males. We found that females that mated with more than one male laid more clutches, exhibited increased egg fertility and invested more in clutches relative to females that mated only once with one male, whereas females that mated twice to the same male were intermediate for these variables. Thus, reproductive success is higher among female leopard geckos that mated with more than one male compared to female leopard geckos that mated only once.

Molecular phylogenetic relationships among species of the Malagasy-Comoran gecko genus Paroedura (Squamata: Gekkonidae)

We use 3100 bp of mitochondrial (ND2, ND4) and nuclear (RAG1, phosducin) DNA sequence data to recover phylogenetic relationships among 14 of the 16 recognized taxa of the lizard genus Paroedura as well as two undescribed forms. These geckos are endemic to Madagascar and the Comores and are popularly kept and bred by herpetoculturalists. The closest relative of Paroedura is another Indian Ocean leaf-toed gecko, Ebenavia. Both Bayesian inference and maximum parsimony strongly support the monophyly of two major clades within Paroedura that conflict with existing species group assignments based on scale characteristics. Our well-resolved tree elucidates a biogeographic pattern in which eastern Paroedura are most basal and western and south-western species form a monophyletic group. Our data demonstrate the phylogenetic utility of phosducin, a novel marker in squamate phylogenetics, at the intrageneric level.

Do female leopard geckos (Eublepharis macularius) discriminate between previous mates and novel males?

Females in numerous taxa engage in mating with more than one male within a breeding season, usually to gain direct or indirect benefits from their male partners. Although effort has been directed towards the benefits females derive from multiple mating, we have less information as to decisions females make when choosing to mate with more than one male and if her decision is contingent upon previous mating experience with a male. In some instances, females must decide whether or not to mate with a previous mate or a novel male, the outcome of which would have ramifications on the acquisition of direct and indirect benefits. In this study, we tested whether female leopard geckos, Eublepharis macularius, would forgo mating with a previous male partner in favor of a novel male. We found no difference in a female's willingness to copulate with a previous mate versus a novel male. However, we found that smaller females initiated copulation termination with a previous mate whereas larger females allowed males to terminate copulations. This pattern was not exhibited when smaller females were paired with novel partners. Thus, smaller females appear to discriminate between previous mates and novel males, favoring novel males as mates.
