Although adaptation of Drosophila to thermal extremes has been investigated for many
years, only recently has much progress been made in identifying the genetic and …

Life-history traits or “fitness components”—such as age and size at maturity, fecundity and
fertility, age-specific rates of survival, and life span—are the major phenotypic determinants …

Life history theory seeks to explain the evolution of the major features of life cycles by
analyzing the ecological factors that shape age-specific schedules of growth, reproduction …

Bergmann's rule states that individuals of a species/clade at higher altitudes or latitudes will
be larger than those at lower ones. A systemic review of the known literature on inter-and …

In insects, species comparisons suggest a weak association between upper thermal limits
and latitude in contrast to a stronger association for lower limits. To compare this to …

Body size is a classic quantitative trait with evolutionarily significant variation within many
species. Locating the alleles responsible for this variation would help understand the …

1. According to their geographical distribution, most Drosophila species may be classified as
either temperate or tropical, and this pattern is assumed to reflect differences in their …

We examined 20 Drosophila melanogaster populations collected from a 2600-km north-
south transect in Australia. In laboratory culture at constant temperature and standard larval …

Founding isofemale lines from wild collected females is a basic tool for investigating the
genetic architecture of Drosophila natural populations. The method permits the analysis of …

Seasonal environmental heterogeneity is cyclic, persistent and geographically widespread.
In species that reproduce multiple times annually, environmental changes across seasonal …
