Associations between fishes (Actinopterygii: Teleostei) and anthozoans (Anthozoa: Hexacorallia) in epipelagic waters based on in situ records

Journal of Fish Biology, Volume 107, Issue 6, Page 2166-2172, December 2025.
Abstract We formally describe the association of fishes and anthozoans in epipelagic waters, extending this relationship to beyond the benthos. In situ observations and photographs of Aluterus schoepfii, Ariomma regulus, Caranx cf. latus and Brama spp.

A Batesian mimic and its model share color production mechanisms

Current Zoology, 2012
Batesian mimics are harmless prey species that resemble dangerous ones (models), and thus receive protection from predators. How such adaptive resemblances evolve is a classical problem in evolutionary biology.

The application of temporal difference learning in optimal diet models [PDF]

, 2014
An experience-based aversive learning model of foraging behaviour in uncertain environments is presented. We use Q-learning as a model-free implementation of Temporal difference learning motivated by growing evidence for neural correlates in natural ...

A mathematical model of population dynamics for Batesian mimicry system [PDF]

Journal of Biological Dynamics, 2012
We analyse a mathematical model of the population dynamics among a mimic, a corresponding model, and their common predator populations. Predator changes its search-and-attack probability by forming and losing its search image. It cannot distinguish the mimic from the model.

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.

Characterising the phenotypic diversity of Papilio dardanus wing patterns using an extensive museum collection [PDF]

, 2014
The history of 20th Century evolutionary biology can be followed through the study of mimetic butterflies. From the initial findings of discontinuous polymorphism through the debates regarding the evolution of mimicry and the step-size of evolutionary ...

Reproductive Barriers and Genomic Hotspots of Adaptation During Allopatric Species Divergence

Molecular Ecology, Volume 34, Issue 21, November 2025.
ABSTRACT Theory predicts that in allopatric populations, genomic divergence and reproductive barriers may be driven by random genetic drift and thereby evolve slowly in large populations. However, local adaptation and divergence under selection may also play important roles, which remain poorly characterised.

Evidences of Batesian Mimicry and Parabiosis in Ants of the Brazilian Savannah

Sociobiology, 2014
Despite the numerous records of ant-mimicking arthropods, reports of ant species that are mimics among themselves are still rare. In the savannah of central Brazil we found two ant species that are remarkably similar in color pattern and body size ...

Predation by avian predators may have initiated the evolution of myrmecomorph spiders

Scientific Reports, 2021
Myrmecomorphy is a strategy utilized by a variety of species, among which spiders are the most common. It is supposed that myrmecomorphy tends to be selected by predator avoidance of preying on ants rather than by blind ant workers.

The evolution of imperfect mimicry in hoverflies [PDF]

, 2004
Ideas about the evolution of imperfect mimicry are reviewed. Their relevance to the colours patterns of hoverflies (Diptera, Syrphidae) are discussed in detail. Most if not all of the hoverflies labelled as mimetic actually are mimics.
