Determining the costs of sexual ornaments is complicated by the fact that ornaments are often integrated with other, non-sexual traits, making it difficult to dissect the effect of ornaments independent of other aspects of the phenotype. Hybridization can produce reduced phenotypic integration, allowing one to evaluate performance across a broad range of multivariate trait values. Here we asses...

Over the past 20 years, researchers have emphasized condition-dependency as a core feature of many sexually selected ornaments. This empirical focus has been motivated by the assumption that condition-dependent ornaments should function as honest indicators of other fitness-related traits. However, evidence remains mixed regarding whether condition-dependent ornaments are consistently correlate...

The immune and the detoxication systems of animals are characterized by allelic polymorphisms, which underlie individual differences in ability to combat assaults from pathogens and toxic compounds. Previous studies have shown that females may improve offspring survival by selecting mates on the basis of sexual ornaments and signals that honestly reveal health. In many cases the expression of t...

We study indeterminacies in realization of ornaments and how they can be incorporated in a stochastic performance model applicable for music information processing such as score-performance matching. We point out the importance of temporal information, and propose a hidden Markov model which describes it explicitly and represents ornaments with several state types. Following a review of the ind...

Expressive performance characterization is traditionally based on the analysis of the main differences between performances, players, playing styles and emotional intentions. This work addresses the characterization of expressive bassoon ornaments by analyzing audio recordings played by a professional bassoonist. This characterization is then used to generate expressive ornaments from symbolic ...

In this paper, crystallographic aspects of ancient, medieval and modern Turkish ornaments are dealt with. Crystallographic patterns (CPs) are considerably different from other patterns. The following are characteristic of CPs: the edge of ornament elements draws the edge of the figure; maximal compactness of the ornament elements; lack of background or transformation of background to ornament e...

The evolution of elaborate secondary sexual traits (i.e., ornaments) is well-studied in males but less so in females. Similarity in the appearance of ornaments between males and females supports the view that female ornaments arise as a neutral byproduct of selection on male traits due to genetic correlation between sexes, but recent research suggests an adaptive function of female ornaments in...

Synopsis Over the past 20 years, researchers have emphasized condition-dependency as a core feature of many sexually selected ornaments. This empirical focus has been motivated by the assumption that condition-dependent ornaments should function as honest indicators of other fitness-related traits.
