Müllerian Mimicry: Sharing the Load Reduces the Legwork
نویسندگان
چکیده
Color pattern mimicry has long been held up as a powerful example of natural selection. A recent study supports the theory by describing Müllerian mimicry rings in Appalachian millipedes that are analogous to those observed in tropical butterflies.

Evolutionary Assembly of Communities in Butterfly Mimicry Rings.
Species co-occurrence in ecological communities is thought to be influenced by multiple ecological and evolutionary processes, especially colonization and competition. However, effects of other interspecific interactions and evolutionary relationships are less explored. We examined evolutionary histories of community members and roles of mutualistic and parasitic interactions (Müllerian and Bat...
متن کاملThe effect of alternative prey on the dynamics of imperfect Batesian and Müllerian mimicries.
Both Batesian and Müllerian mimicries are considered classical evidence of natural selection where predation pressure has, at times, created a striking similarity between unrelated prey species. Batesian mimicry, in which palatable mimics resemble unpalatable aposematic species, is parasitic and only beneficial to the mimics. By contrast, in classical Müllerian mimicry the cost of predators' av...
متن کاملThe importance of pattern similarity between Müllerian mimics in predator avoidance learning.
Müllerian mimicry, where unpalatable prey share common warning patterns, has long fascinated evolutionary biologists. It is commonly assumed that Müllerian mimics benefit by sharing the costs of predator education, thus reducing per capita mortality, although there has been no direct test of this assumption. Here, we specifically measure the selection pressure exerted by avian predators on unpa...
متن کاملNorth American velvet ants form one of the world’s largest known Müllerian mimicry complexes
Color mimicry is often celebrated as one of the most straightforward examples of evolution by natural selection, as striking morphological similarity between species evolves in response to a shared predation pressure. Recently, a large North American mimetic complex was described that included 65 species of Dasymutilla velvet ants (Hymenoptera: Mutillidae). Beyond those 65 species, little is kn...
متن کاملMutualistic mimicry enhances species diversification through spatial segregation and extension of the ecological niche space.
Species richness varies among clades, yet the drivers of diversification creating this variation remain poorly understood. While abiotic factors likely drive some of the variation in species richness, ecological interactions may also contribute. Here, we examine one class of potential contributors to species richness variation that is particularly poorly understood: mutualistic interactions. We...
