Sexual size dimorphism in anurans.
Several hypotheses have been proposed to explain the direction and extent of sexual size dimorphism in anurans (in which males are usually smaller than females) as a result of sexual selection. Here, we present an analysis to test the hypothesis that sexual dimorphism in anurans is largely a function of differences between the sexes in life-history strategies. Morphological and demographic data...
متن کاملBody size and sexual size dimorphism in primates: influence of climate and net primary productivity.
Understanding the evolution of body size and sexual size dimorphism has been a longstanding goal in evolutionary biology. Previous work has shown that environmental stress can constrain male-biased sexual size dimorphism at the population level, but we know little about how this might translate to geographical patterns of body size and sexual size dimorphism at the species level. Environmental ...
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 کاملJuvenile hormone mediates sexual dimorphism in horned beetles.
The causes and consequences of sexual dimorphism are major themes in biology. Here we explore the endocrine regulation of sexual dimorphism in horned beetles. Specifically, we explore the role of juvenile hormone (JH) in regulating horn expression in females of two species with regular sexual dimorphism for pronotal horns (females have much shorter horns than males) and a third species with a r...
متن کاملIntraspecific Body Size Variation in Ground Beetles (coleoptera, Carabidae) in Urban – Suburban – Rural – Natural Gradient
This study aims to analyse how body size of Ground Beetles (Coleoptera, Carabidae) is controlled by environmental factors. Beetles were sampled in different regions of Russia. Sampling plots included urban, suburban, rural and natural habitats. We have measured elytron length of more than 25000 specimen. The study was conducted on intraspecific level and six species of carabids were investigate...
