Seasonal polyphenism in Bicyclus (Lepidoptera: Satyridae) butterflies: different climates need different cues

Publikováno v: Biological Journal of the Linnean Society. 66:345-356

A comparison is made between northern and southern hemisphere populations of Bicyclus butterflies in Africa regarding their responses in wing pattern polyphenism to seasonal change in rainfall and temperature. In southern habitats where temperature a

Publikováno v: Evolution. 50:2360-2372

Temperature-induced variation and norms of reaction have been analyzed for wing pattern elements of six species belonging to the African butterfly genus Bicyclus (Lepidoptera, Nymphalidae, Satyrinae). Five of these species are sympatric in Malawi and

Exploring evolutionary constraints is a task for an integrative evolutionary biology

Autor: J. C. Roskam, Paul M. Brakefield

Publikováno v: The American naturalist. 168

Judging by the volume of writings about evolutionary constraints, they are an important topic in evolutionary biology. However, their involvement in shaping patterns of evolutionary change from morphological stasis to adaptive radiation remains conte
