Female Columbian ground squirrels ( Spermophilus columbianus (Ord, 1815)) sometimes emit a repetitive vocalization after copulation. We examined two possible explanations for why sexual selection would favor expression of these “estrus calls”: to encourage sperm competition through mating with additional males and to increase mate guarding by the consort male as a mechanism of postcopulatory female mate choice. During three annual mating periods, we observed mating behaviour, estrus calls, and postcopulatory behavioural interactions of free-ranging individuals. Predictions of the advertisement hypothesis were supported, as females typically solicited courtship interactions with nonconsort males directly after emitting an estrus call. Thus, females that emitted an estrus call were more likely to acquire additional matings than noncalling females, particularly if calls were emitted after the female’s first mating. These results were not consistent with predictions of the postcopulatory female mate choice hypothesis, as calling females should initiate social contact with the consort male and stay proximate to the copulatory site after copulation if they are encouraging mate guarding. For reasons that remain unclear, the probability that an estrus call would follow mating increased linearly with the age of the consort male. However, our results taken together suggest that estrus advertisement is the most likely social context of female postcopulatory calling.

Grasshopper Warbler

Abstract Morphological and territorial factors that influence female mate choice were examined in the monogamous Middendorff's Grasshopper-Warbler (Locustella ochotensis) on an islet near Fukuoka, Japan. I assumed that pairing date corresponded with female mate choice. Pairing date was correlated with both territory size and food abundance but was not correlated with selected morphological characteristics of males. Territorial quality was assumed to be correlated with territory size because preferable food resources and nest sites were distributed randomly. I conclude that female mate choice was influenced by territory quality rather than by the morphological characteristics of males.

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.

Colour Patterns

Butterflies are among nature's most colourful animals, and provide a living showcase for how extremely bright, chromatic and iridescent coloration can be generated by complex optical mechanisms. The gross characteristics of male butterfly colour patterns are understood to function for species and/or sex recognition, but it is not known whether female mate choice promotes visual exaggeration of this coloration. Here I show that females of the sexually dichromatic species Hypolimnas bolina prefer conspecific males that possess bright iridescent blue/ultraviolet dorsal ornamentation. In separate field and enclosure experiments, using both dramatic and graded wing colour manipulations, I demonstrate that a moderate qualitative reduction in signal brightness and chromaticity has the same consequences as removing the signal entirely. These findings validate a long-held hypothesis, and argue for the importance of intra- versus interspecific selection as the driving force behind the exaggeration of bright, iridescent butterfly colour patterns.
