“…Because we were interested in separating the within-and among-family effects of chirp duration on chirp rate, two separate predictor variables were derived for each male from the chirp duration measures [46,47]: mean family chirp duration (the mean of the male's family) and within-family deviation in chirp duration (the male's deviation from the family mean). The models included chirp rate as the dependent variable and four fixed factors: mean family chirp duration, within-family deviation in chirp duration, nutritional environment and the interaction between mean family chirp duration and nutritional environment.…”

Tradeoffs limit the evolution of male traits that are attractive to females

Tradeoffs occur between a variety of traits in a diversity of organisms, and these tradeoffs can have major effects on ecological and evolutionary processes. Far less is known, however, about tradeoffs between male traits that affect mate attraction than about tradeoffs between other types of traits. Previous results indicate that females of the variable field cricket, Gryllus lineaticeps, prefer male songs with higher chirp rates and longer chirp durations. In the current study, we tested the hypothesis that a tradeoff between these traits affects the evolution of male song. The two traits were negatively correlated among full-sibling families, consistent with a genetically based tradeoff, and the tradeoff was stronger when nutrients were limiting. In addition, for males from 12 populations reared in a common environment, the traits were negatively correlated within populations, the strength of the tradeoff was largely invariant across populations, and the within-population tradeoff predicted how the traits have evolved among populations. A widespread tradeoff thus affects male trait evolution. Finally, for males from four populations assayed in the field, the traits were negatively correlated within and among populations. The tradeoff is thus robust to the presence of environmental factors that might mask its effects. Together, our results indicate there is a fundamental tradeoff between male traits that: (i) limits the ability of males to produce multiple attractive traits; (ii) limits how male traits evolve; and (iii) might favour plasticity in female mating preferences.

“…For a locally adapted trait, it would even be possible to differentiate markers explaining among-population phenotypic variability (by testing for among-population effects) from markers explaining within-population variability (by testing for within-population effects). The technique of within-group centring (Davis et al, 1961;van de Pol and Wright, 2009) could be used to this end. It simply consists in distinguishing between the mean-population effect and the within-population effect of each predictor of an association model, as follows:…”

The study of local adaptation is rendered difficult by many evolutionary confounding phenomena (for example, genetic drift and demographic history). When complex traits are involved in local adaptation, phenomena such as phenotypic plasticity further hamper evolutionary biologists to study the complex relationships between phenotype, genotype and environment. In this perspective paper, we suggest that the common garden experiment, specifically designed to deal with phenotypic plasticity, has a clear role to play in the study of local adaptation, even (if not specifically) in the genomic era. After a quick review of some high-throughput genotyping protocols relevant in the context of a common garden, we explore how to improve common garden analyses with dense marker panel data and recent statistical methods. We then show how combining approaches from population genomics and genome-wide association studies with the settings of a common garden can yield to a very efficient, thorough and integrative study of local adaptation. Especially, evidence from genomic (for example, genome scan) and phenotypic origins constitute independent insights into the possibility of local adaptation scenarios, and genome-wide association studies in the context of a common garden experiment allow to decipher the genetic bases of adaptive traits.

“…The application of mixed models to longitudinal data has bypassed this major limitation and revealed that within-and between-individual effects can differ in many situations and that both can result in a positive association between age and trait expression at the population level (van de Pol and Verhulst 2006;van de Pol and Wright 2009;Rebke et al 2010). Most longitudinal studies published to date have analyzed key life-history traits, such as reproductive success (e.g., Dugdale et al 2011;Froy et al 2013) and survival (e.g., Bouwhuis et al 2012), but there is growing interest in age-dependent variation in secondary sexual traits (Balbontín et al 2011;Evans et al 2011) and behavior (Mainguy and Côté 2008;Nussey et al 2009).…”

“…However, only longitudinal studies can separate within-individual (i.e., phenotypic plasticity, individual improvement, senescence) and between-individual (i.e., selective appearance or disappearance of certain phenotypes) effects of age on trait expression (van de Pol and Verhulst 2006;van de Pol and Wright 2009). As individual trajectories can be hidden by demographic heterogeneity (Bouwhuis et al 2009;van de Pol and Wright 2009;Evans et al 2011), neglecting within-individual effects might lead to incorrect conclusions about the effects of aging on life histories.…”

Dryad data: http://dx.doi.org/10.5061/dryad.rg8d4.abstract: Age is a major factor explaining variation in life-history traits among individuals with typical patterns of increasing trait values early in life, maximum trait expression, and senescence. However, age-dependent variation in the expressions of sexually selected traits has received less attention, although such variation underpins differences in male competitive abilities and female preference, which are central to sexual selection. In contrast to previous studies focusing on single traits, we used repeated measures of seven sexually selected morphological and behavioral traits in male black grouse (Tetrao tetrix) to quantify the effects of age and life span on their expressions and quantified this variation in relation to male reproductive effort. Trait expression increased with age, but long-lived males had a slower increase and delayed maxima in trait values compared with shortlived males. There was evidence of terminal investment (increasing trait values during the last breeding season) in some traits and senescence in all traits. These trait dynamics were largely explained by the timing of male peak lekking effort. This study shows that fully understanding the variation in sexually selected traits and fitness benefits associated with sexual selection requires accounting for the complex interaction among individual age, life span, and the timing of individuals' investment in reproduction.
