“…Plasticity in female mating preferences is favored by the confluence of environmental patchiness and variation in an assessable male trait under habitat-imposed viability selection (see Alonzo and Sinervo 2001;Doty and Welch 2001;Welch 2003). Migration between habitats further relaxes the conditions that favor plastic phenotypes (Sultan and Spencer 2002).…”

“…With temporal or spatial variation in genotype quality, plastic mate preferences may be favored over static mate preferences (Lesna and Sabelis 1999; Doty and Welch 2001;Welch 2003). Context-dependent female choice for good genes could then promote adaptive response to prevailing ecological conditions without eroding variation in the male traits on which preferences are based (Jia et al 2000;Labeyrie et al 2003).…”

Abstract. In Georgia (USA) the soldier beetle, Chauliognathus pennsylvanicus (Coleoptera; Cantharidae), exhibits clinal variation in the length of the spot on its elytron. This suggests that the viability of phenotypes varies by habitat. Evidence of viability selection comes from within-site changes in the spot length distribution across a breeding season. When males with spots of intermediate length became less frequent, they became disproportionately less likely to mate, consistent with either a loss of vigor among remaining males or female rejection of disfavored phenotypes. Persistent, daily courtship by males provides females with the opportunity to track changes in male phenotype frequency and to exercise choice for phenotypes favored under natural selection. A laboratory experiment in which the frequency of one spot morph (long) or the other (short) was increased from 25% to 75% over a period of 30 days revealed that females possess a flexible preference that leads them to prefer whichever spot type has become more common over time. A haploid genetic model demonstrates that a flexible female preference for the locally favored male phenotype can be selected for when different viability alleles, genetically correlated with the male trait, are favored in different habitats that are linked by gene flow. Thus, migration between different kinds of habitat patches of a metapopulation could maintain the variation in male quality. This variation favors female choice for any trait that is directly or indirectly favored by natural selection. Such choice imparts positive frequency-dependent selection that could rapidly fix traits pleiotropically linked to viability. Rapid fixation would cause differentiation between populations of colonizing species as females exercise choice for mates favored under new ecological conditions.

“…However, it is now recognized that benefits from mate choice can depend on the genetic match between males and females or the ecological and social context (e.g., Qvarnström 2001;Welch 2003;Suk and Choe 2008). Recently, Chaine and Lyon (2008) showed that individual female lark buntings (Calamospiza melanocorys) change their preferences for particular male traits between years.…”

Optimization of Resource Allocation Can Explain the Temporal Dynamics and Honesty of Sexual Signals

In species in which males are free to dynamically alter their allocation to sexual signaling over the breeding season, the optimal investment in signaling should depend on both a male's state and the level of competition he faces at any given time. We developed a dynamic optimization model within a game-theoretical framework to explore the resulting signaling dynamics at both individual and population levels and tested two key model predictions with empirical data on three-spined stickleback (Gasterosteus aculeatus) males subjected to dietary manipulation (carotenoid availability): (1) fish in better nutritional condition should be able to maintain their signal for longer over the breeding season, resulting in an increasingly positive correlation between nutritional status and signal (i.e., increasing signal honesty), and (2) female preference for more ornamented males should thus increase over the breeding season. Both predictions were supported by the experimental data. Our model shows how such patterns can emerge from the optimization of resource allocation to signaling in a competitive situation. The key determinants of the honesty and dynamics of sexual signaling are the condition dependency of male survival, the initial frequency distribution of nutritional condition in the male population, and the cost of signaling.

16The evolutionary origin and the maintenance of extra-pair mating in birds has been a major 17 field of study in the last decades, but no consensus has been reached on the adaptive 18 significance of this behaviour for female birds. The genetic benefit hypothesis proposes that 19 extra-pair sires provide alleles of superior quality and/or better compatibility compared to the 20 social mate, resulting in offspring of higher reproductive value. One frequently adopted 21 approach to test this idea compares the performance of maternal half-siblings in broods with 22 multiple paternity. However, results from such comparisons are inconsistent. Here I discuss the 23 idea that the magnitude of genetic fitness benefits from extra-pair mating depends on the 24 environmental context. Context-dependent genetic effects in maternal half-sibling comparisons 25 have been demonstrated for only five passerine bird species up to date. In none of the studies 26were the crucial environmental conditions experimentally manipulated and the potentially 27 confounding effects of differential maternal investment in relation to paternity were mostly not 28 accounted for either. A number of high-quality data sets on fitness consequences of extra-pair 29 mating behaviour are available that could be (re-) analysed for context-dependence given 30
