A Müllerian mimicry ring in Appalachian millipedes.
Few biological phenomena provide such an elegant and straightforward example of evolution by natural selection as color mimicry among unrelated organisms. By mimicking the appearance of a heavily defended aposematic species, members of a second species gain protection from predators and, potentially, enhanced fitness. Mimicking a preexisting warning advertisement is economical because a potenti...
متن کاملMüllerian mimicry in aposematic spiny plants.
Müllerian mimicry is common in aposematic animals but till recently, like other aspects of plant aposematism was almost unknown. Many thorny, spiny and prickly plants are considered aposematic because their sharp defensive structures are colorful and conspicuous. Many of these spiny plant species (e.g., cacti and Agave in North American deserts; Aloe, Euphorbia and acacias with white thorns in ...
متن کاملMimics here and there, but not everywhere: Müllerian mimicry in Ceroglossus ground beetles?
The ground beetle genus Ceroglossus contains co-distributed species that show pronounced intraspecific diversity in the form of geographical colour morphs. While colour morphs among different species appear to match in some geographical regions, in others, there is little apparent colour matching. Mimicry is a potential explanation for covariation in colour patterns, but it is not clear whether...
متن کاملMüllerian Mimicry: Sharing the Load Reduces the Legwork
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.
متن کاملInvestigating Müllerian mimicry: predator learning and variation in prey defences.
Inexperienced predators are assumed to select for similarity of warning signals in aposematic species (Müllerian mimicry) when learning to avoid them. Recent theoretical work predicts that if co-mimic species have unequal defences, predators attack them according to their average unpalatability and mimicry may not be beneficial for the better defended co-mimic. In this study, we tested in a lab...
