Elaborate morphological ornaments can evolve if they increase the reproductive success of the bearer during competition for mates. However, ornament evolution is incredibly rare in females, and the type and intensity of selection required to develop female-specific ornamentation is poorly understood. The main goals of my thesis are to clarify the relationship between the type and intensity of s...

Why are there so few small secondary sexual characters? Theoretical models predict that sexual selection should lead to reduction as often as exaggeration, and yet we mainly associate secondary sexual ornaments with exaggerated features such as the peacock's tail. We review the literature on mate choice experiments for evidence of reduced sexual traits. This shows that reduced ornamentation is ...

Most studies of condition-dependent sexual ornaments have treated such ornaments as single traits. However, sexual ornaments are often composites of several components, each produced by partially independent developmental pathways. Depending on environmental and individual condition, components of these ornaments may reflect different behavioral or physiological properties of an individual. One...

Mate choice can lead to the evolution of sexual ornamentation. This idea rests on the assumption that individuals with more elaborate ornaments than competitors have higher reproductive success due to gaining greater control over mating decisions and resources provided by partners. Nevertheless, how the resources and quality of sexual partners that individuals gain access to are influenced by t...

Explaining the presence of conspicuous female ornaments that take the form of male-typical traits has been a longstanding challenge in evolutionary biology. Such female ornaments have been proposed to evolve via both adaptive and nonadaptive evolutionary processes. Determining the genetic underpinnings of female ornaments is important for elucidating the mechanisms by which such female traits a...

 Culture transitions as a result of globalization, even being forgotten by modern society. This shift in local culture occurs various aspects, one which is traditional buildings. The existence buildings must be maintained and applied because have national identity that has philosophical values their uniqueness, very different from One the elements wealth presence ornaments. spe...

Long-tailed dance flies, Rhamphomyia longicauda (Diptera: Empididae), show a striking reversal in the typical pattern of animal sexual dimorphism. Whereas male R. longicauda are mosquito-like in appearance, females sport rows of scales on their legs and have elaborate eversible pleural (abdominal) sacs that are inflated just prior to entry into a female competitive mating swarm. Both sets of or...

This paper presents an automatic system for the detection of singleand multi-note ornaments in Irish traditional flute playing. This is a challenging problem because ornaments are notes of a very short duration. The presented ornament detection system is based on first detecting onsets and then exploiting the knowledge of musical ornamentation. We employed onset detection methods based on signa...
