“…Although the fact that a genetic correlation between larval development and pupal mass could not be demonstrated is certainly interesting, it does not necessarily imply that the anticipated trade-off is, in general, absent. Windig (1994) for instance, found a weak negative genetic correlation between these traits in B. anynana. Such variable outcomes might be expected in sufficiently complex multivariate systems (e.g.…”

Realized correlated responses to artificial selection on pre-adult life-history traits in a butterfly

We use artificial selection experiments targeted on egg size, development time or pupal mass within a single butterfly population followed by a common-garden experiment to explore the interactions among these life-history traits. Relationships were predicted to be negative between egg size and development time, but to be positive between development time and body size and between egg size and body size. Correlated responses to selection were in part inconsistent with these predictions. Although there was evidence for a positive genetic correlation between egg and body size, there was no support for genetic correlations between larval development time and either egg size or pupal mass. Phenotypic correlations among the three target traits of selection gave comparable results for the relationships between egg mass and development time (no association) as well as between egg mass and pupal mass (positive association), but not for the relation between development time and pupal mass (negative phenotypic correlation). In summary, correlated responses to selection as well as phenotypic correlations were rather unpredictable. The impact of variation in acquisition and allocation of energy as well as of the benign conditions used deserve further investigation. Heredity (2007) 98, 157-164.

“…The effect of temperature on genetic correlations between life history traits has been examined in a number of recent experiments (Windig, 1994;de Jong and Imasheva, 2001;Norry and Loeschcke, 2002). Windig (1994) examined the effect of a range of temperatures (17-281C) on the genetic correlations between development time, pupal weight and two wing pattern characters, seasonal form and thermal form, in the tropical dry-wet seasonal polyphenic butterfly Bicyclus anynana.…”

Seasonal form is comprised of wing patterns, while thermal form is comprised largely of wing size and colour.…”

Genetic correlations, tradeoffs and environmental variation

2004

Negative genetic correlations among traits are often used as evidence for tradeoffs that can influence evolutionary trajectories in populations. While there may be evidence for negative correlations within a particular environment, genetic correlations can shift when populations encounter different environmental conditions. Here we review the evidence for these shifts by focusing on experiments that have examined genetic correlations in more than one environment. In many studies, there are significant changes in correlations and these can even switch sign across environments. This raises questions about the validity of deducing genetic constraints from studies in one environment and suggests that the interaction between environmental conditions and the expression of genetic covariation is an important avenue for future work.

“…For example, adult females in Madeira are larger and colour is paler in females as in other populations of P. aegeria , and indeed other satyrine butterflies such as Bicyclus anynana (Windig, 1994b). We know that adult colour plays an important role in thermoregulation and that it is related to territorial behaviour in males in Belgium.…”

Quantitative genetic variation in an island population of the speckled wood butterfly (Pararge aegeria)

2004

Evidence of changes in levels of genetic variation in the field is scarce. Theoretically, selection and a bottleneck may lead to the depletion of additive genetic variance (V A ) but not of nonadditive, dominance variance (V D ), although a bottleneck may converse V D to V A . Here we analyse quantitative genetic variation for the Speckled Wood butterfly Pararge aegeria on the island of Madeira about 120 generations after first colonisation. Colonisation of the island involved both a bottleneck and strong natural selection, changing the average value of traits. Several life history and morphological traits with varying levels of change since colonisation were analysed. In accordance with expectations, all traits except one showed relatively low levels of V A , with an average heritability (h 2 ) of 0.078. Levels of V D for these traits were relatively high, 20-94% of total variance and on average 80% of V G . The exception was a morphological trait that probably had not experienced strong natural selection after colonisation, for which a h 2 of 0.27 was found. Another interesting observation is that the population seems resistant to inbreeding effects, which may be the result of purging of deleterious alleles.
