Phenotypic plasticity in sex pheromone production in Bicyclus anynana butterflies
Phenotypic plasticity refers to the environmental control of phenotypes. Cues experienced during development (developmental plasticity) or during adulthood (acclimatization) can both affect adult phenotypes. Phenotypic plasticity has been described in many traits but examples of developmental plasticity in physiological traits, in particular, remain scarce. We examined developmental plasticity ...

متن کاملSex Determination: Controlling the Master
Sex is determined in Drosophila by the activity of the Sex-lethal master regulator. Activity of Sex-lethal is initiated early in females by chromosome-counting transcription factors, then reinforced by signaling through the Janus kinase pathway.
متن کاملSex Chromosome Mosaicism and Hybrid Speciation among Tiger Swallowtail Butterflies
Hybrid speciation, or the formation of a daughter species due to interbreeding between two parental species, is a potentially important means of diversification, because it generates new forms from existing variation. However, factors responsible for the origin and maintenance of hybrid species are largely unknown. Here we show that the North American butterfly Papilio appalachiensis is a hybri...
متن کاملSex, butterflies and molecular biology: when pigmentation met mimicry
Pigmentation, specifically melanism, is often the driving force behind classic examples of natural selection such as camouflage and mimicry. However, whilst pigmentation in insects has long been considered the exclusive preserve of the genetic model Drosophila, stunning new papers on the molecular basis of melanism and mimicry in butterflies are beginning to show how evolution can act directly ...
