In contrast, the frequency of copulations was significantly affected by female size as log(number of spermatodoses) increased by 0.41 ± 0.27 per each 0.1 mm of pronotum length. However, interactions between the body size (the trait that predicts females’ quality for reproduction) with environmental factors revealed that larger females originating from the highland population and larger females reared in cold treatment copulated more often than smaller ones, whereas females’ size did not affect copulation frequency in the lowland population or in warm treatment. It suggests stronger competition among females in harsher environmental conditions, whereas effect sizes of interaction terms showed that observed mating behaviour expressed a similar extent of genetic and plastic responses to female size. This first observation of environment-associated body size-dependent mating behaviour suggests the interplay of sexual and natural selection in a nuptial gift-giving species. |
