Sexual selection in females

Sexual selection in males and females.

Research on sexual selection shows that the evolution of secondary sexual characters in males and the distribution of sex differences are more complex than was initially suggested but does not undermine our understanding of the evolutionary mechanisms involved. However, the operation of sexual selection in females has still received relatively little attention. Recent studies show that both int...

females are more anxious than males a metacognitive perspective

ôbjective: previous studies have suggested that anxiety disorders are more prevalent among women than men. the purpose of this study was to compare the metacognitive perspective of generalized ânxiety disorder (gâd) in females with males. methods: â cross sectional study was conducted on the high school girls and boys who have been affected by gâd. the sample consisted of 100 high school studen...

Dispersal influences genetic and acoustic spatial structure for both males and females in a tropical songbird

Animals exhibit diverse dispersal strategies, including sex-biased dispersal, a phenomenon common in vertebrates. Dispersal influences the genetic structure of populations as well as geographic variation in phenotypic traits. Patterns of spatial genetic structure and geographic variation may vary between the sexes whenever males and females exhibit different dispersal behaviors. Here, we examin...

Sleep apnoea is a common occurrence in females.

Obstructive sleep apnoea (OSA) is primarily regarded as a male disorder, presenting with snoring, daytime sleepiness and cardiovascular disease. We aimed to determine the frequency of sleep apnoea among females in the general population. We investigated 400 females from a population-based random sample of 10,000 females aged 20-70 yrs. They answered a questionnaire and performed overnight polys...
