Speciation with gene flow is greatly facilitated when traits subject to divergent selection also
contribute to non-random mating. Such traits have been called 'magic traits', which could be …

There is abundant evidence that the probability of successful establishment in novel
environments increases with number of individuals in founder groups and with number of …

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 …

Reptiles use pterin and carotenoid pigments to produce yellow, orange, and red colors.
These conspicuous colors serve a diversity of signaling functions, but their molecular basis …

Adaptation is commonly a multidimensional problem, with changes in multiple traits required
to match a complex environment. This is epitomized by balanced polymorphisms in which …

Biological diversity is threatened by exploitation, fragmentation of natural habitats, pollution,
climate change, and anthropogenic spread of species. The question of how among …

The signalling function of melanin‐based colouration is debated. Sexual selection theory
states that ornaments should be costly to produce, maintain, wear or display to signal quality …

Colour polymorphism exemplifies extreme morphological diversity within populations,. It is
taxonomically widespread but generally rare. Theory suggests that where colour …

Polymorphic species, in which multiple variants coexist within a population, are often used
as model systems in evolutionary biology. Recent research has been dominated by the …

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