“…In addition, above the threshold, as courtship rate increased, a male's likelihood of copulating increased. Female preferences for male courtship rate have been documented for a wide range of animals including, but not limited to, orthopterans, homopterans and anurans (reviewed in Gerhardt & Huber 2002), fiddler crabs (Backwell et al, 1999;Murai and Backwell, 2006), birds and mammals (reviewed in Byers et al 2010), and wolf spiders (Kotiaho et al, 1998a;Parri et al, 2002;Rypstra et al, 2003;Delaney et al, 2007;Gibson and Uetz, 2008;Lomborg and Toft, 2009;Shamble et al, 2009;Rundus et al, 2010). Thus, our findings that female choice depends upon courtship rate and that higher courtship rates result in faster copulations in S. stridulans were not unexpected.…”

“…Previous work on a closely related species (S. ocreata) has shown that the male signaling observed in male-male interactions (i.e. the same species-specific signaling used in male-female contexts) does not influence the outcome of these interactions (Delaney et al 2007). Thus, although possible, it seems unlikely that male ornamentation functions in intrasexual encounters.…”

“…While early Schizocosa studies focused on the relationship between ornamentation and female choice (McClintock and Uetz, 1996;Scheffer et al, 1996;Hebets and Uetz, 2000;Uetz and Roberts, 2002;Hebets et al, 2006;Uetz and Norton, 2007), more recent studies have highlighted the importance of these active displays, as courtship rate has been shown to influence male mating success across multiple species of wolf spider (Kotiaho et al, 1998a;Parri et al, 2002;Rypstra et al, 2003;Delaney et al, 2007;Gibson and Uetz, 2008;Lomborg and Toft, 2009;Shamble et al, 2009;Rundus et al, 2010Rundus et al, , 2011. Female Schizocosa are considered mostly monandrous (Norton & Uetz 2005), and previous work has documented strong female mate choice across species (e.g.…”

“…floridana -Rundus et al, 2011). Male visual signaling associated with ornamentation does not predict male-male agonistic interactions either (at least not in S. ocreata), suggesting that it does not function in intra-sexual selection (Delaney et al, 2007). Such results then raise the questions: Why do so some Schizocosa species possess seemingly elaborate 'ornaments' and are females exerting selection on such male secondary sexual traits?…”

Female mate choice for multimodal courtship and the importance of the signaling background for selection on male ornamentation

Conspicuous visual ornaments are frequently incorporated into complex courtship displays that integrate signal components from multiple sensory modalities. Mature male Schizocosa crassipes (Walckenaer, 1837) wolf spiders wave, arch, and tap their ornamented forelegs in a visual courtship display that simultaneously incorporates seismic components. To determine the importance of modality-specific signal components in female mate choice, we used a signal ablation design and compared the mating frequency of female-male pairs across signaling environments with manipulated modality-specific transmission properties. We found that the successful transmission of isolated visual or seismic signaling was sufficient for mating success; neither signaling modality was necessary. Additionally, the environment enabling the successful transmission of composite, multimodal displays yielded the highest mating frequencies. Our results indicate the presence of selection from S. crassipes females for multimodal courtship and suggest that multimodal signaling may facilitate mating across variable signaling environments. We next explored the influence of ornamentation per se on female choice by phenotypically manipulating males into two groups: (i) intact (brushes present) and (ii) shaved (brushes absent). We compared the mating frequencies of intact versus shaved males in the presence versus absence of seismic signaling. Males with brushes intact had higher mating frequencies than shaved males, but only under specific signaling conditions -in the presence of seismic signaling. Female choice for male brushes then appears dependent on the signaling background, making brushes themselves an unlikely target of direct selection. Our results emphasize the complex nature of female choice, highlighting the potential for both trait interactions and environment-dependent selection [Current Zoology 59 (2): 200-209, 2013].

Abstract. The study of courtship behavior provides a useful tool for identifying cryptic species due to the qualitative differences that can be observed in closely related species. Here, we present an overview of visual courtship displays of 26 European species of the genus Pardosa C.L. Koch 1847, including new quantitative and qualitative data. Thirty-five recurring courtship elements are described and illustrated by means of drawings, photos and videos (available online). In general terms, complex movements of the palps, the first pair of legs and the abdomen characterize courtship displays in the genus Pardosa. The most complex movements are performed by the palps, while legs and abdomen mainly oscillate in the air or vibrate on the substrate. We noticed a high level of complexity in almost all of the species, both in terms of sensory modes involved and number of courtship elements composing the displays. No apparent relationships emerged when considering ethological similarities among species, attesting to the relative independence between morphological and ethological characters.
