DESCRIPTION:Little is known about the genetic variation that affects life 
 history trait variation in wild populations of outcrossing species. Ongoin
 g work in the Glanville fritillary butterfly (Melitaea cinxia) has identif
 ied coding\, expression\, and indel polymorphism that appears to be involv
 ed in adult dispersal variation among demes of a metapopulation. Additiona
 l studies have recently been conducted on larval growth rate variation in 
 the same system\, revealing extensive heritable variation that interacts w
 ith thermal variation. Global analysis of gene expression variation underl
 ying larval growth rate variation reveals significant expression variation
  in the same categories of genes previously identified as differing in adu
 lt butterflies in relation to metapopulation dynamics. This observation su
 pports the notion of a life-history syndrome put forward based on ecologic
 al studies. These findings suggest that metapopulation dynamics in heterog
 eneous environments maintain genetic variation that affects the regulation
  of life history traits.
