Allometric and Non-Allometric Patterns in Sexual Dimorphism Discrimination of Wing Shape in Ophion intricatus: Might Two Male Morphotypes Coexist?
Bees and wasps could exhibit shape and size sexual dimorphism, and most of their morphological variation could depend on phenotypic responses due to environmental pressure during ontogenetic development. More complex measurement techniques related to size and shape rather than simply to mass and length should be required to analyze such a complex sexual dimorphism. In this study, differences re...
متن کاملSexual dimorphism in the wing shape and size of the carob moth, Ectomyelois ceratoniae (Lepidoptera: Pyralidae)
پروانه‌ی کرم گلوگاه انار، Ectomyelois ceratoniae (Zeller) ، به خانواده‌ی Pyralidae و زیر خانواده‌ی Phycitinae تعلق دارد. علیرغم وجود شواهدی دال بر وجود اختلاف شکل و اندازه در جنس‌های نر و ماده‌ی بسیاری از پروانه‌ها و همچنین در اعضای این خانواده، وجود چنین اختلافی تاکنون در گونه‌ی مورد بحث گزارش نشده است. در تحقیق حاضر، دوشکلی جنسی در اندازه و شکل بال پروانه‌ی کرم گلوگاه انار روی چهار میزبان انا...
متن کاملsexual dimorphism in the wing shape and size of the carob moth, ectomyelois ceratoniae (lepidoptera: pyralidae)
the carob moth, ectomyelois ceratoniae (zeller), belongs to the family pyralidae and the subfamily phycitinae. in spite of some features of sexual dimorphism in size and shape in the order lepidoptera and the mentioned family, it has not been recorded in this species. in the current study, sexual dimorphism in the wing shape and size of carob moth on four hosts (pomegranate, fig, pistachio and ...
متن کاملSexual size dimorphism in musteloids: An anomalous allometric pattern is explained by feeding ecology
Rensch's rule states that sexual size dimorphism (SSD) increases with body size in taxa where males are larger, and decreases when females are larger. The dominant explanation for the trend is currently that competitive advantage for males is greater in larger individuals, whereas female size is constrained by the energetics of rearing offspring. This rule holds for a variety of vertebrate taxa...
متن کاملWing shape, wing size, and sexual dimorphism in eye-span in stalk-eyed flies (Diopsidae)
The eyes of stalk-eyed flies (Diopsidae) are positioned at the end of rigid peduncles (‘stalks’) protruding laterally from the head. Eye-stalk length varies within the family and, in some species, varies between males and females. Larger eye-stalks in males result from sexual selection for longer stalks, a trait that increases male reproductive success. In the present study, we examined whether...
