This study addresses the general hypothesis that insects living in seasonal environments
should shorten development times at progressively later dates in the growth season, and …

In this study we investigate how the need for seasonal timing of diapause and sexual
maturation have selected for plasticity in life history traits in two butterfly species …

We investigated whether interpopulational variation in life-cycle regulation and life-history
plasticity, in response to photoperiod, is predictable from considerations of what would be …

Plasticity is a major component of phenotypic variation, interrelated with genetic
differentiation through the existence of genetic variation in reaction norms. Phenotypic …

In temperate insects the evolution of growth strategies and the optimal age and size at
maturity will depend strongly on seasonal variation in temperature and other resources …

In recent years there has been a strong increase in the interest in animal life-history plasticity
(eg, Stearns and Koella 1986; Gebhardt and Stearns 1988; West-Eberhard 1989; Kindlmann …

Regulation of growth and development by photoperiod was studied in a population of the
speckled wood butterfly, Purarge aegeria L.(Lepidoptera: Satyrinae), from southern Sweden …

Life-history theory predicts some cost to be associated with short development time, the most
frequently assumed being small adult size. Alternatively, insects may increase …

Climate change allows species to expand polewards, but non‐changing environmental
features may limit expansions. Daylength is unaffected by climate and drives life cycle timing …

The temporal aspects of life cycle characteristics, such as diapause development, are under
strong selection in seasonal environments. Fine‐tuning of the life cycle may be particularly …
