If sexual dimorphism positively covaries with primary sexual traits, such as gonads and genitalia, then it seems likely that the dimorphism results from increased investment in sexual processes, and would be consistent with the interpretation of dimorphism resulting from sexual selection [ 7 , 14 , 15 ]. These anatomical characters may evolve in response to extrinsic, environmental factors, to distinct reproductive demands of each sex, and to sexual selection, subject to physiological constraints. Estimates of directional asymmetry are most variable when sample sizes are low, but then stabilize with increasing statistical power to values with left-side structures being 0. However, a few studies have indicated that dimorphism in size, color, and even behavioral traits can result from evolutionary change in females, and not as a direct product of sexual selection [ 3 , 4 , 6 ].

Our results suggest a complex interaction between hard and soft anatomy, with a direct, moderate correlation between sexual dimorphism of the valve and sexual traits. The Goals model was then used to assess the potential impact at country level of responding to epidemics among MSM.

The different patterns of static allometry between the basal capsule and the terminal extension suggests that these structures may indeed experience distinct evolutionary dynamics, as does the observation that the basal capsule is conserved across members of the genus whereas the terminal extension is highly divergent in size and shape [ 30 ]. Sweeney collected some of the outline data and also assisted in the photomicroscopy. Massage slagelse sex i ålborg obtain a measure of body size related to softparts, linear dimensions were measured from four non-sexually dimorphic limbs: In males, this limb is broader and markedly curved compared with the left 1WL Fig 2A—2Fwhich retains the shape observed in females.
