Mutualistic interactions drive ecological niche convergence in a diverse butterfly community. [PDF]
PLoS Biology, 2008 Ecological communities are structured in part by evolutionary interactions among their members. A number of recent studies incorporating phylogenetics into community ecology have upheld the paradigm that competition drives ecological divergence among ...

Divergence with gene flow across a speciation continuum of Heliconius butterflies [PDF]
, 2015 BACKGROUND: A key to understanding the origins of species is determining the evolutionary processes that drive the patterns of genomic divergence during speciation.

eLife, 2021 Müllerian mimicry is a positive interspecific interaction, whereby co-occurring defended prey species share a common aposematic signal. In Lepidoptera, aposematic species typically harbour conspicuous opaque wing colour patterns with convergent optical ...

Phenotypic and Genetic Divergence among Poison Frog Populations in a Mimetic Radiation. [PDF]
PLoS ONE, 2013 The evolution of Müllerian mimicry is, paradoxically, associated with high levels of diversity in color and pattern. In a mimetic radiation, different populations of a species evolve to resemble different models, which can lead to speciation.

Interspecific visual signalling in animals and plants: a functional classification [PDF]
, 2017 Organisms frequently gain advantages when they engage in signalling with individuals of other species. Here we provide a functionally structured framework of the great variety of interspecific visual signals seen in nature, then describe the different ...

Royal Society Open Science, 2023 Predation is expected to promote uniformity in the warning coloration of defended prey, but also mimicry convergence between aposematic species. Despite selection constraining both colour-pattern and population divergence, many aposematic animals display

The diversification of Heliconius butterflies: what have we learned in 150 years? [PDF]
, 2015 Research into Heliconius butterflies has made a significant contribution to evolutionary biology. Here, we review our understanding of the diversification of these butterflies, covering recent advances and a vast foundation of earlier work.

Natural hybridization in heliconiine butterflies: the species boundary as a continuum [PDF]
, 2007 Background: To understand speciation and the maintenance of taxa as separate entities, we need information about natural hybridization and gene flow among species.Results: Interspecific hybrids occur regularly in Heliconius and Eueides (Lepidoptera ...

Signal categorization by foraging animals depends on ecological diversity
eLife, 2019 Warning signals displayed by defended prey are mimicked by both mutualistic (Müllerian) and parasitic (Batesian) species. Yet mimicry is often imperfect: why does selection not improve mimicry?
