An evolutionary task analysis predicts a connection between disgust and human mating, two
important but currently disconnected areas of psychology. Because short-term mating …

It is poorly understood whether female morphological and behavioural traits can be used as
'signals'. In particular, experimental tests of the hypothesis that female ornaments reflect …

It is well known that being given ''silver spoons''can be beneficial to offspring, in the sense
that conditions experienced early in life can have long-lasting consequences (Lindström …

The general hypothesis of mate choice based on non-additive genetic traits suggests that
individuals would gain important benefits by choosing genetically dissimilar mates …

Plumage coloration is generally perceived as a static trait and therefore not a good indicator
of current condition. However, changing of feather colors after molt does occur and may …

Summary 1 We test the consequences, in terms of breeding success and parental effort, of
eggshell pigmentation pattern in a hole‐nesting bird, the blue tit Cyanistes caeruleus that …

Besides the direct functionality of nests driven by natural selection, accumulating evidence
shows that nest building behaviors and nests may also evolve under sexual selection …

To study biologically relevant variation in visual signals, these need to be assessed in
relation to the sensory abilities of receivers. For the study of colors, reflectance spectrometry …

Despite the importance of proximate mechanisms for understanding costs and functions of
signals, relatively little is known about physiological processes underlying colorful plumage …

Automated animal monitoring via radio‐frequency identification (RFID) technology allows
efficient and extensive data sampling of individual activity levels and is therefore commonly …
