Sexual Size Dimorphism and Body Condition in the Australasian Gannet
Sexual size dimorphism is widespread throughout seabird taxa and several drivers leading to its evolution have been hypothesised. While the Australasian Gannet (Morus serrator) has previously been considered nominally monomorphic, recent studies have documented sexual segregation in diet and foraging areas, traits often associated with size dimorphism. The present study investigated the sex dif...
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 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 کاملGeographic variation in body size and sexual size dimorphism of a seed-feeding beetle.
Body size of many animals varies with latitude: body size is either larger at higher latitudes (Bergmann's rule) or smaller at higher latitudes (converse Bergmann's rule). However, the causes underlying these patterns are poorly understood. Also, studies rarely explore how sexual size dimorphism varies with latitude. Here we investigate geographic variation in body size and sexual size dimorphi...
متن کاملEcological drivers of body size evolution and sexual size dimorphism in short-horned grasshoppers (Orthoptera: Acrididae).
Sexual size dimorphism (SSD) is widespread and variable in nature. Although female-biased SSD predominates among insects, the proximate ecological and evolutionary factors promoting this phenomenon remain largely unstudied. Here, we employ modern phylogenetic comparative methods on eight subfamilies of Iberian grasshoppers (85 species) to examine the validity of different models of evolution of...
