Female mate rejection acts as a major selective force within species, and can serve as a reproductive barrier between species. In spite of its critical role in fitness and reproduction, surprisingly little is known about the genetic or neural basis of variation in female mate choice. Here, we identify fruitless as a gene affecting female receptivity within Drosophila melanogaster , as well as female Drosophila simulans rejection of male D. melanogaster . Of the multiple transcripts this gene produces, by far the most widely studied is the sex-specifically spliced transcript involved in the sex determination pathway. However, we find that female rejection behaviour is affected by a non-sex-specifically spliced fruitless transcript. This is the first implication of fruitless in female behaviour, and the first behavioural role identified for a fruitless non-sex-specifically spliced transcript. We found that this locus does not influence preferences via a single sensory modality, examining courtship song, antennal pheromone perception, or perception of substrate vibrations, and we conclude that fruitless influences mate choice via the integration of multiple signals or through another sensory modality.

Higher Sensitivity

Microphonic potentials were recorded from the inner ear of anesthetized adult and juvenile Notophthalmus viridescens, adult Plethodon cinereus, and larval Ambystoma maculatum lying prostrate in air on a horizontally vibrating platform. At temperatures of 15–17 °C, responses were obtained from all groups over the frequency range 20 Hz to 500–650 Hz. At 20–22 °C, adult N. viridescens responded to 1100 Hz. Microphonics were produced over a maximum vibration amplitude range of 0.011–35 μm peak-to-peak displacement, but the range limits varied at individual frequencies. A lower range limit, or higher sensitivity, was found for adult N. viridescens at 20–22 °C than at 15–I7 °C. The amplitude of the response increases nonlinearly with increasing vibration amplitude and does not adapt to a steady-state vibration. Microphonics were double the frequency of the stimulus, indicating that the receptors have hair cells of opposite polarization. Inner ear sense organ activity can occur in salamander ears in response to gross substrate vibration. The variety of response characteristics found indicates a versatile sensory system.

Substrate Vibrations

AbstractSensing vibrations that propagate through solid substrates conveys fundamental information about moving objects and other nearby dynamic events. Here we report that neurons responsive to substrate vibrations applied to the mouse forelimb reveal a new way of representing frequency information in the primary somatosensory cortex (S1). In contrast to vibrotactile stimulation of primate glabrous skin, which produces temporally entrained spiking and frequency independent firing rates, we found that mouse S1 neurons rely on a different coding scheme: their spike rates are conspicuously tuned to a preferred frequency of the stimulus. Histology, peripheral nerve block and optogenetic tagging experiments furthermore reveal that these responses are associated with the activation of mechanoreceptors located in deep subdermal tissue of the distal forelimb. We conclude that the encoding of frequency information of substrate-borne vibrations in the mouse S1 might be analogous to the representation of pitch of airborne sound in auditory cortex.

Substrate Vibrations

Intraspecific acoustic communication via substrate vibrations is common in Hemiptera. Pear psyllids are economically important as vectors of pear decline phytoplasmas. Their mating behaviour has not been previously studied. We recorded the first acoustic signals emitted by male C. pyri. Further studies will clarifiy the importance of these signals for mate finding and mate choice in this pest species.

Different Levels

Animals may use a variety of sensory modalities to assess ownership and resource-holding potential (RHP). However, few studies have experimentally tested whether animals can assess these key variables through a purely vibrational modality, exclusively involving substrate-borne vibrations. Here we studied social terrestrial hermit crabs ( Coenobita compressus ), where competitors assess homeowners by climbing on top of a solid external structure—an architecturally remodelled shell home, inside of which the owner then produces vibrations. In the field, we used a miniature vibratory device, hidden within an empty shell, to experimentally simulate a ‘phantom owner’, with variable amplitudes of vibration representing different levels of homeowner strength. We found that assessors could use these vibrations to deduce the owner's RHP: for strong vibrations (indicative of a high RHP owner) assessors were least likely to escalate the conflict; for weak vibrations (indicative of a low RHP owner) assessors showed intermediate escalation; and in the absence of vibration (indicative of an extremely weak or absent owner) assessors were most likely to escalate. These results reveal that animals can assess homeowner strength based solely on substrate vibrations, thereby making important decisions about whether to escalate social conflicts over property.
