Historical demography of Mullerian mimicry in the neotropical Heliconius butterflies.
We compare the historical demographies of two Müllerian comimetic butterfly species: Heliconius erato and Heliconius melpomene. These species show an extensive parallel geographic divergence in their aposematic wing phenotypes. Recent studies suggest that this coincident mosaic results from simultaneous demographic processes shaped by extrinsic forces over Pleistocene climate fluctuations. Howe...
متن کاملWing shape variation associated with mimicry in butterflies.
Mimetic resemblance in unpalatable butterflies has been studied by evolutionary biologists for over a century, but has largely focused on the convergence in wing color patterns. In Heliconius numata, discrete color-pattern morphs closely resemble comimics in the distantly related genus Melinaea. We examine the possibility that the shape of the butterfly wing also shows adaptive convergence. Fir...
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 ...
متن کاملConvergent evolution in the genetic basis of Müllerian mimicry in heliconius butterflies.
The neotropical butterflies Heliconius melpomene and H. erato are Müllerian mimics that display the same warningly colored wing patterns in local populations, yet pattern diversity between geographic regions. Linkage mapping has previously shown convergent red wing phenotypes in these species are controlled by loci on homologous chromosomes. Here, AFLP bulk segregant analysis using H. melpomene...
متن کاملThe diversity and evolution of batesian mimicry in Papilio swallowtail butterflies.
Papilio swallowtail butterflies exhibit a remarkable diversity of Batesian mimicry, manifested in several sex-limited and polymorphic types. There is little understanding of how this diversity is distributed within Papilio, and how different mimicry types have evolved in relation to each other. To answer these questions, I present a graphical model that connects various mimicry types by hypothe...
