Evolutionary dynamics of multilocus microsatellite arrangements in the genome of the butterfly Bicyclus anynana, with implications for other Lepidoptera
The sequences flanking microsatellites isolated from the butterfly Bicyclus anynana display high levels of similarity among different loci. We examined sequence data for evidence of the two mechanisms most likely...

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 ...

Genetic and environmental sources of egg size variation in the butterfly Bicyclus anynana
By dividing families of the tropical butterfly, Bicyclus anynana, among different larval (including early pupal) and adult (including late pupal) temperatures, we investigate the genetic and environmental effects...

Chemical defence in a sawfly: genetic components of variation in relevant life-history traits
Larvae of several tenthredinid sawfly species readily release droplets of haemolymph through their integument when attacked by predators. This defence mechanism via ‘bleeding’ is characterised by a low integum...

On the developmental theory of ageing. II. The effect of developmental temperature on longevity in relation to adult body size in D. melanogaster
Flies from a wild type strain of Drosophila melanogaster, previously kept at 25°C, were reared at either 20,25 or 29°C. As expected, developmental time and adult body size decreased with increasing temperature. A...

On the developmental theory of ageing. I. Starvation resistance and longevity in Drosophila melanogaster in relation to pre-adult breeding conditions
The developmental theory of ageing predicts a positive correlation between developmental time and adult longevity. Experiments that vary larval density and food level have been carried out to test this predict...
