The transition from 'well-marked varieties' of a single species into 'well-defined species'—
especially in the absence of geographic barriers to gene flow (sympatric speciation)—has …

Transposable elements (TEs) are mobile genetic sequences present within host genomes.
TEs can contribute to the evolution of host traits, since transposition is mutagenic and TEs …

Polymorphisms have fascinated biologists for a long time, but their genetic underpinnings
often remain elusive. Here, we aim to uncover the genetic basis of the gold/dark …

Increased predation risk is considered a cost of having conspicuous colours, affecting the
anti-predator behaviour of colourful animals. However, this is difficult to test, as individual …

Abstract The Nicaraguan Midas cichlid species complex is a natural experiment where fish
from a large source population from turbid and shallow great lakes very recently (< 20,000 …

Background Color polymorphisms are a conspicuous feature of many species and a way to
address broad ecological and evolutionary questions. Three potential major evolutionary …

Abstract Background Central American crater lake cichlid fish of the Midas species complex
(Amphilophus spp.) are a model system for sympatric speciation and fast ecological …

Despite long‐standing interest in the evolution and maintenance of discrete phenotypic
polymorphisms, the molecular genetic basis of such polymorphism in the wild is largely …

Phenotypic plasticity, particularly during development, allows organisms to rapidly adjust to
different environmental conditions. Yet, it is often unclear whether the extent and direction of …

Individual variation in the behavior of prey can influence predation risk in complex ways. We
ran individual roach (Rutilus rutilus), a common freshwater fish, through a standard refuge …
