Feature theory and the two-step hypothesis of Müllerian mimicry evolution

, 2010
The two-step hypothesis of Müllerian mimicry evolution states that mimicry starts with a major mutational leap between adaptive peaks, followed by gradual fine-tuning.

The Impact of Detoxification Costs and Predation Risk on Foraging: Implications for Mimicry Dynamics.

PLoS ONE, 2017
Prey often evolve defences to deter predators, such as noxious chemicals including toxins. Toxic species often advertise their defence to potential predators by distinctive sensory signals.

Müllerian Mimicry and pollinators decline

, 2023
La plupart des espèces de guêpes et d’abeilles (Aculeata) ont des motifs colorés et des couleurs marquées. Ces colorations sont souvent interprétées comme un signal dit aposématique, traduisant leur moyen de défense qu’est l’aiguillon venimeux.

How the Easter Egg Weevils got their spots: Phylogenomics reveals Müllerian mimicry in Pachyrhynchus (Coleoptera, Curculionidae)

, 2022
The evolutionary origins of mimicry in the Easter Egg weevil, Pachyrhynchus, have fascinated researchers since first noted more than a century ago by Alfred Russel Wallace.

Signals, cues and the nature of mimicry

, 2017
‘Mimicry’ is used in the evolutionary and ecological literature to describe diverse phenomena. Many are textbook examples of natural selection's power to produce stunning adaptations. However, there remains a lack of clarity over how mimetic resemblances

The evolution of multi-component mimicry

, 2006
The relative sizes of phenotypic mutations contributing to evolutionary change has long been the subject of debate. We describe how mimicry research can shed light on this debate, and frame mimicry studies within the general context of macromutationism ...

Figure 1 in Are goldish spiders able to teach naïve predators to avoid bullet ants? A possible case of Müllerian mimicry in spiders and ants

Proportions of aposematic colouration in bees and wasps (Hymenoptera, Aculeata) and their main mimics – hoverflies, clearwing moths and longhorn beetles [PDF]

Journal of Hymenoptera Research
Although bees and wasps are well known as aposematically coloured insects, the role of their aposematic patterns has not been studied to the same extent as other animal and insect groups, i.e., butterflies or beetles.

Wing patterning genes and coevolution of Müllerian mimicry inHeliconiusbutterflies: Support from phylogeography, cophylogeny, and divergence times

Examples of long-term coevolution are rare among free-living organisms. Müllerian mimicry in Heliconius butterflies had been suggested as a key example of coevolution by early genetic studies.

Experimental evidence for predator learning and Müllerian mimicry in Peruvian poison frogs (Ranitomeya, Dendrobatidae)

, 2013
Poison frogs are characterized by bright coloration, striking patterns, and toxicity; they have thus become a classic example of aposematism. Ranitomeya imitator mimics three congeneric model species (R. fantastica, R.
