In many areas of animal behaviour research, improvements in our ability to collect large and
detailed data sets are outstrip** our ability to analyse them. These diverse, complex and …

The world in color presents a dazzling dimension of phenotypic variation. Biological interest
in this variation has burgeoned, due to both increased means for quantifying spectral …

Recent technical and methodological advances have led to a dramatic increase in the use of
spectrometry to quantify reflectance properties of biological materials, as well as models to …

To understand the function of colour signals in nature, we require robust quantitative
analytical frameworks to enable us to estimate how animal and plant colour patterns appear …

Our view of the evolution of sexually selected traits and preferences was influenced radically
in the 1990s by studies that emphasized how signals interact with sensory properties of …

The Extended Specimen highlights the research potential for ornithological specimens, and
is meant to encourage ornithologists poised to initiate a renaissance in collections-based …

It has long been suggested that tropical species are generally more colourful than temperate
species, but whether latitudinal gradients in organismal colourfulness exist remains …

The recognition that animals sense the world in a different way than we do has unlocked
important lines of research in ecology and evolutionary biology. In practice, the subjective …

The avian plumage color gamut is the complete range of plumage colors, as seen by birds
themselves. We used a tetrahedral avian color stimulus space to estimate the avian …

Sexual selection is proposed to be a powerful driver of phenotypic evolution in animal
systems. At macroevolutionary scales, sexual selection can theoretically drive both the rate …
