Xenophilic Mating Preferences Among Populations Of The Jumping Spider Habronattus Pugillis Griswold, Eileen Hebets, Wayne P. Maddison

Sexual selection is thought to have driven the diversification of courtship behavior and associated ornamentation between geographically isolated populations of the jumping spider Habronattus pugillis Griswold. In an attempt to understand the pathways of sexual selection during this diversification, we conducted reciprocal mating trials between two populations of H. pugillis (Santa Rita [SR] and Atascosa [AT]) that differ in both male courtship display and secondary sexual ornamentation. Observations of mating frequencies show a xenophilic mating preference in which SR females have a stronger response to AT males than to SR males, while AT females show no difference in mating frequency. …

Attention-Altering Signal Interactions In The Multimodal Courtship Display Of The Wolf Spider Schizocosa Uetzi, Eileen Hebets

Complex signals are common throughout the animal kingdom, consisting of one or more signals in one or more sensory modalities presented within a single display. I tested an efficacy-based backup hypothesis of complex signal function using the bimodal courtship signaling wolf spider Schizocosa uetzi. This hypothesis predicts that the visual and vibratory courtship displays function as backups to each other in the presence of environmental variability. I compared mating frequencies across four environmental treatments in which the visual and vibratory environments were manipulated independently in a 2 × 2 design with visual treatments of light/dark (i.e., visual signal present/absent) …

The diversity of courtship displays throughout the animal kingdom is immense and displays can range from seemingly simple, to incredibly complex. Signalers often possess elaborate morphological adaptations for signals directed at a specific sensory modality in receivers. In some cases, these signals are so compelling to human observers, the possibility that important signals exist in other sensory modalities is ignored, potentially resulting in an incomplete characterization of the communication system. Jumping spiders (Salticidae) have remarkable visual capabilities. Yet one species, Habronattus dossenus, has recently been shown to have a complex repertoire of multicomponent seismic courtship signals in addition to …

The basic building blocks of communication are signals, assembled in various sequences and combinations, and used in virtually all inter- and intra-specific interactions. While signal evolution has long been a focus of study, there has been a recent resurgence of interest and research in the complexity of animal displays. Much past research on signal evolution has focused on sensory specialists, or on single signals in isolation, but many animal displays involve complex signaling, or the combination of more than one signal or related component, often serially and overlapping, frequently across multiple sensory modalities. Here, we build a framework of functional …
