Ever since Darwin, researchers have tried to explain the enormous diversity of plumage color traits in birds. Now researchers are adding something new to this particular field of research, which is so ...

For plants that rely on animals for pollination, the ability to attract the animals to their flowers can be a crucial component of fitness. A large number of studies have documented pollinators to be ...

Flower colour variation is a fundamental trait in angiosperms, serving not only to enhance the visual appeal of flowers but also to mediate interactions with a wide range of pollinators. The diversity ...

Knowledge of the mechanism underlying the expression of melanin-based sex-traits may help us to understand their signalling function. Potential sources of inter-individual variation are the total ...

A key aspect of biodiversity is the great quantitative variation in functional traits observed among species. One perspective asserts that trait values should converge on a single optimum value in a ...
