vibratory communication in the jumping spider phidippus clarus polyandry male courtship signals and Mating Success
Behavioral Ecology, 2010Co-Authors: Andrew C Mason, Senthurran Sivalinghem, Maydianne C B Andrade, Michael M Kasumovic, Damian O EliasAbstract:The jumping spider Phidippus clarus uses signals that combine visual and substrate-borne vibrations, which predict the outcome of male–male competition and are important to copulation Success. We investigated the function of males’ substrate-borne vibrations by examining phenotypic correlates of vibratory signal traits and assessing whether these affect female Mating and reMating decisions. Virgin females were first paired with males, and females that copulated in first trials were then paired with a second male to determine whether females remate. We measured vibratory signals produced by males during these interactions to determine 1) correlations between substrate-borne signal traits and male phenotypes, 2) whether properties of substrate-borne signals predicted Mating Success in first and second copulations, and 3) whether females of different Mating status have different acceptance thresholds for male characters. Courtship vibration rate was positively correlated with male leg size, and signaling rate significantly predicted Mating Success in all copulations. Some females were polyandrous; however, copulation with mated females occurred after longer courtship durations, and courtship duration was positively correlated with male size, demonstrating that mated females are less receptive to mates and suggesting that females may be trading up in subsequent Matings. Our study shows that males invest significant effort in courtship and that sexual selection via female choice may play a nontrivial role in the Mating system. These results are the first to show that honest information about male size is encoded by substrate vibrations, and these signals are important for male Mating Success in both virgin and mated females. Key words: female Mating status, honest indicator, jumping spiders, mate choice, Phidippus, polyandry, sexual selection, substrate-borne vibrations. [Behav Ecol]

vibratory communication in the jumping spider phidippus clarus substrate borne courtship signals are important for male Mating Success
Ethology, 2010Co-Authors: Damian O Elias, Senthurran Sivalinghem, Andrew C Mason, Maydianne C B Andrade, Michael M KasumovicAbstract:Recently, work has shown that multimodal communication is common throughout the animal kingdom but the function of multimodal signals is still poorly understood. Phidippus clarus are jumping spiders in which males produce multimodal (visual and vibrational) signals in both male-male (aggressive) and male-female (courtship) contexts. The P. clarus Mating system is complex, with sex ratios and the level of male competition changing over the course of the breeding season. Vibrational signal components have been shown to function in male aggressive contests but their role in courtship has not been investigated. Here, we performed an experiment to test the role of vibrational signaling in courtship by observing Mating Success for males that were experimentally muted. We show that vibratory courtship signals, and in particular signaling rate, is an important component of Mating Success and potentially a target of female choice. While the ability to produce vibratory signals significantly increased Mating Success, some muted males were still able to Successfully mate. In these trials, signaling rate also predicted Mating Success suggesting that redundant signal components may compensate for errors and perturbations in signal transmission or that vibratory signals function to enhance the efficacy of visual signals.
