| 1 | A signal-substrate match in the substrate-borne component of a multimodal courtship display显示文摘The environment can impose strong limitations on the efficacy of signal transmission. In particular, for vibratorycommunication, the signaling environment is often extremely heterogeneous at small scales. Nevertheless, natural selection isexpected to select for signals well-suited for effective transmission. Here, we test for substrate-dependent signal efficacy in thewolf spider Schizocosa stridulans Stratton 1991. We first explore the transmission characteristics of this important signaling modalityby playing recorded substrate-borne signals through three different substrates (leaf litter, pine litter, and red clay) andmeasuring the propagated signal. We found that the substrate-borne signal of S. stridulans attenuates the least on leaf litter, thesubstrate upon which the species is naturally found. Next, by assessing mating success with artificially muted and non-mutedmales across different signaling substrates (leaf litter, pine litter, and sand), we explored the relationship between substrate-bornesignaling and signaling substrate for mating success. We found that muted males were unsuccessful in obtaining copulations regardlessof substrate, while mating success was dependent on the signaling substrate for non-muted males. For non-muted males,more males copulated on leaf litter than any other substrate. Taken together, these results confirm the importance of substrate-borne signaling in S. stridulans and suggest a match between signal properties and signal efficacy - leaf litter transmits thesignal most effectively and males are most successful in obtaining copulations on leaf litter [Current Zoology 56 (3): 370-378,2010]. | Damian O.ELIAS Andrew C.MASON Eileen A.HEBETS | 2010 | Current Zoology2010，56，3： | 6 |
