Abstract
Developmental plasticity is a well-known individual survival strategy. Organisms are usually limited in their ability to read environmental cues and to integrate present and past information for optimally adjusting their phenotype to the state of their environment. Our study was designed to evaluate the effects of experimental selection on the ontogenesis of developmental variants under standard laboratory conditions. Developmental plasticity of the ladybird Propylea dissecta (Mulsant) (Coleoptera: Coccinellidae) is known but experimental evolution studies are still lacking. Our data revealed the effects of selection based on developmental rate over 15 generations. The selection resulted into two variants and showed an elevation of the adult body mass after 15 generations for fast developers. The ratio of the two developmental variants changes according to the applied selective pressure but is bimodal in both (F1 and F15) the generations.
期刊介绍：
Animal Biology publishes high quality papers and focuses on integration of the various disciplines within the broad field of zoology. These disciplines include behaviour, developmental biology, ecology, endocrinology, evolutionary biology, genomics, morphology, neurobiology, physiology, systematics and theoretical biology. Purely descriptive papers will not be considered for publication.
Animal Biology is the official journal of the Royal Dutch Zoological Society since its foundation in 1872. The journal was initially called Archives Néerlandaises de Zoologie, which was changed in 1952 to Netherlands Journal of Zoology, the current name was established in 2003.
