Leader Preference

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Many species of acoustically communicating insects and anurans display a female preference for males producing their calls just ahead of those of their neighbors. The evolutionary origin of these preferences is unclear. We test whether leader preference is adaptive in Neoconocephalus katydids. The ability to produce leading calls was not correlated with male quality in a species with leader preference or two closely related species without the preference. However, in N. ensiger, the species with the preference, females mating with leaders produced higher quality offspring than those mating with followers. This suggested that leader preference is adaptive and selected for in this species. The ability to produce leading calls was not heritable, meaning that the preference cannot have an evolutionary effect on the male trait and they will not become coupled. Male N. ensiger adjust the timing of their chirps relative to their neighbors, which leads to synchrony within a chorus. The mechanism used by N. ensiger males differs from that of all previously described species with acoustic synchrony. Neoconocephalus ensiger males adjust their actual intrinsic chirp rate to match that of other males. The characteristics that determine a male's ability to produce leading calls and the specific source of the female fitness benefit are yet unknown.

Novel Alleles

Males in many species have elaborated sexual traits that females strongly prefer, and these traits often conspicuously differ among species. How novel preferences and traits originate, however, is a challenging evolutionary problem because the initial appearance of only the female preference or only the male trait should reduce the ability to find a suitable mate, which could reduce fitness for individuals possessing those novel alleles. Here, we present a hypothesis for how novel preferences, as well as the novel male traits that females prefer, can originate, be favoured and spread in polyandrous species. Novel preference mutations can arise as ‘veiled preferences’ that are not expressed when the corresponding male trait is not present in the population, allowing preferences to be hidden from selection, and thus persist. In those cases when a male trait is present, veiled preferences provide a selective advantage, and females disproportionately produce offspring from preferred males through either mate choice or cryptic female choice. This tips the fitness advantage for novel males, allowing both preference and trait to spread, and limiting selection against them in the absence of the corresponding trait or preference.

Kirkpatrick Model

Abstract A key element at the heart of the Fisher–Lande–Kirkpatrick model of the sexual selection process is the genetic correlation between (male) trait and (female) preference. The strength of this association is critical in determining a population’s evolutionary trajectory, which is why estimating its magnitude is so important. In the Lande model, the trait-preference correlation is solely established and maintained by mate choice, and although it is unclear how exclusively mate choice does this in nature, the experimental designs typically employed to measure trait-preference genetic correlations could be systematically weakening estimates by not allowing free mate choice (similarly with husbandry practices). The precise impact of the problem is unknown, and possibly unknowable, but simple solutions can be applied to ensure the accuracy of trait-preference correlation estimates is maximized.
