Thus, subspecific and population-specific predictive models of sex identification are critical not only for establishing sex of shrikes in-hand, but also for understanding patterns of geographic variation in sexual dimorphism
Studies focused on length-weight relationships in captive held individuals show that sexual dimorphism
is common in freshwater crayfish species (Lindqvist & Lahti 1983; Holdich 2001; Mazlum et al.
2008a), the findings of the present study suggest that environmental PCB exposures may affect behavioral sexual dimorphism
, as evidenced by modification of play behaviors, toy preferences, and sex-typical characteristics as reported by their mothers or parents.
Emmi Schlicht and Bart Kempenaers of the Max Planck Institute for Ornithology in Seewiesen investigated whether this could be the driving force behind the evolution of sexual dimorphism

If Persons' hypothesis is true, then scientists may eventually find evidence of sexual dimorphism
, as in birds, with a flashy male and a comparatively less ostentatious female.

DIAGNOSIS: Pinophylus is distinguished from other conifer inhabiting genera of Phylini by the distinctive sexual dimorphism
, with the costal margins of the hemelytra elongate and parallel-sided in the male and shorter and subovoid in the female; the brownish black dorsum with inconspicuous dark simple setae; the pretarsus with the base of the claw expanded and the pulvillus small; and the endosoma composed of two straps with a subapical secondary gonopore.
