uathg asymmetry and sexual selection

چکیده
I nterest in fluctuating asymmetry, FA (Box l), has recently spread across diverse disciplines in the life sciences, including medicine, genetics, conservation and developmental biology, and behavioral ecologysl. FA allows researchers to evaluate a basic aspect of viability fitness, namely, developmental stability the capacity to develop properly in the face of genetic and environmental stresses that tend to upset development. Behavioral ecologists have recently begun asking whether random deviations from bilateral symmetry in individuals (i.e. in traits that show FA at the population level) Behavioral ecologists are being attracted to the study of withlrrindivldual morphological variability, manifested in random deviations from bilateral symmetry, as a means of ascertaining the stress susceptibiltty of developmental regulatory mechanisms. Several early successes indicate that incorporating measures of symmetry into sexual-selection studies may help link indlvldual sexual success to a basic component of viability developmental stability

Hummingbird responses to gender-biased nectar production: are nectar biases maintained by natural or sexual selection?
Pollinators mediate the evolution of secondary floral traits through both natural and sexual selection. Gender-biased nectar, for example, could be maintained by one or both, depending on the interactions between plants and pollinators. Here, I investigate pollinator responses to gender-biased nectar using the dichogamous herb Chrysothemis friedrichsthaliana (Gesneriaceae) which produces more n...
متن کاملEfficiency and Information Asymmetry in the Iranian Banking System
The soundness and efficiency of banks is one of the important subjects that neglecting it can have adverse consequences for every country's economy. For economies depending on the money market, such as the Iran economy, this subject is more critical. Therefore, in this study, using panel data related to 16 Iranian banks for the annual period of 2010-2017, the economic efficiency was determined ...

The aim of the present study was to examine students’ attachment to parents, sexual knowledge and attitude and attitude to mate selection in divorced and normal families. The statistical population consisted of all female high school students in Korramabad in the academic year 2017-18. 180 students (90 from divorced and 90 from normal families ) participated in this study, completing the Atta...
متن کاملFluctuating Asymmetry in Flies, What Does It Mean?
The degree of departure from perfect symmetry in organisms, fluctuating asymmetry (FA), is seen in most populations of animals. It has particular impact on choice of mate which lies within the world of sexual selection. Here I consider a relatively little studied aspect of sexual selection, i.e. the effect of FA on contests between males for mates, based not on display ornament but rather on ag...
