Sexual selection accounts for the geographic reversal of sexual size dimorphism in the dung fly, sepsis punctum (Diptera: Sepsidae).
Sexual size dimorphism (SSD) varies widely across and within species. The differential equilibrium model of SSD explains dimorphism as the evolutionary outcome of consistent differences in natural and sexual selection between the sexes. Here, we comprehensively examine a unique cross-continental reversal in SSD in the dung fly, Sepsis punctum. Using common garden laboratory experiments, we esta...
متن کاملLongevity and Developmental Stability in the Dung Fly Sepsis cynipsea, as Affected by the Ectoparasitic Mite, Pediculoides mesembrinae
Fluctuating asymmetry (FA) is a widely employed measure of developmental stability. It has been found to increase with many stressors including parasite infection. Associations between parasites and FA may exist for several reasons in addition to parasites being the direct cause of increased FA. Developmentally stable individuals may have superior immune systems, and be less susceptible to para...
متن کاملSelection on morphological traits and fluctuating asymmetry by a fungal 2 parasite in the yellow dung fly
11 Evidence for selective disadvantages of large body size remains scarce in general. Previous 12 phenomenological studies of the yellow dung fly Scathophaga stercoraria have demonstrated 13 strong positive sexual and fecundity selection on male and female size. Nevertheless, the body 14 size of flies from a Swiss study population has declined by almost 10% from 1993 to 2009. 15 Given substanti...
