Stress-mediated covariance between nano-structural architecture and ultraviolet butterfly coloration
1. Structural coloration is a striking component of sexual ornamentation, and may function as a signal of mate quality. Although the proximate optical mechanisms are often well defined, we know much less about the morphological basis for intraspecific variation in structural colour. 2. Males of the butterfly Colias eurytheme L. possess a thin-film interference array on their dorsal wing scales ...
متن کاملCondition dependence, quantitative genetics, and the potential signal content of iridescent ultraviolet butterfly coloration.
Structural colors result from an interaction between light and the fine-scale physical structure of a surface, and are often extremely bright, chromatic, and iridescent. Given that these visual features depend upon the aggregate abundance and architectural precision of photonic structures, structurally colored sexual ornaments seem well placed to indicate a range of mate quality characteristics...
متن کاملVariability of the Structural Coloration in Two Butterfly Species with Different Prezygotic Mating Strategies
Structural coloration variability was investigated in two Blue butterfly species that are common in Hungary. The males of Polyommatus icarus (Common Blue) and Plebejus argus (Silver-studded Blue) use their blue wing coloration for conspecific recognition. Despite living in the same type of habitat, these two species display differences in prezygotic mating strategy: the males of P. icarus are p...
متن کاملBrain Structural Covariance Network Topology in Remitted Posttraumatic Stress Disorder
Posttraumatic stress disorder (PTSD) is a prevalent, chronic disorder with high psychiatric morbidity; however, a substantial portion of affected individuals experience remission after onset. Alterations in brain network topology derived from cortical thickness correlations are associated with PTSD, but the effects of remitted symptoms on network topology remain essentially unexplored. In this ...
متن کاملEarly Islamic Architecture and Structural Configurations
Islam spread rapidly after its founding, encompassing much of North Africa, the Middle East, and Southeast Asia. The art of this vast region draws its distinctive character both from Islam itself and from the diverse cultural traditions of the world’s Muslims. Because Islam discouraged the use of figurative images, particularly in religious contexts- unlike Christian art- Islamic artists develo...
