Cichlid fishes constitute one of the most species-rich families of vertebrates. In addition to
complex social behaviour and morphological versatility, they are characterised by extensive …

Genetic colour polymorphisms are widespread across animals and often subjected to
complex selection regimes. Traditionally, colour morphs were used as simple visual markers …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

It has been 25 years since the formalization of the Sensory Drive hypothesis was published
in the American Naturalist (1992). Since then, there has been an explosion of research …

Fish populations are increasingly being subjected to anthropogenic changes to their
sensory environments. The impact of these changes on inter-and intra-specific …

Communication in complex environments poses challenges of potential loss of intended
messages, but some animals may compensate by using multimodal signalling. Courtship …

Environmental noise that reduces the probability that animals will detect communicative
signals poses a special challenge for long-range communication. The application of signal …

Temperature rules the lives of ectotherms. To perform basic biological functions, ectotherms
must make behavioral adjustments to keep their body temperatures near a preferred …

Within species, color morphs may enhance camouflage, improve communication and/or
confer reproductive advantage. However, in the male cichlid Astatotilapia burtoni, body color …

There are now a number of well‐studied cases in which hybridization between closely
related sympatric species has increased, sometimes resulting in the replacement of species …
