Size-dependent alternative male mating tactics in the yellow dung fly, Scathophaga stercoraria.
Whenever males can monopolize females and/or resources used by females, the opportunity for sexual selection will be great. The greater the variation among males in reproductive success, the greater the intensity of selection on less competitive males to gain matings through alternative tactics. In the yellow dung fly, Scathophaga stercoraria, males aggressively compete for access to receptive,...
متن کاملPolymorphic DNA microsatellites identified in the yellow dung fly (Scathophaga stercoraria).
Sperm competition in yellow dung flies (Scathophaga stercoraria) has been extensively investigated since Parker's (1970a) seminal work (e. These flies serve as a model system for understanding the mechanisms and outcomes of sperm competition in internal fertilizers. Invariably however, these investigations have been laboratory based, and typically involved competition between only two males. Ho...
متن کاملHeteropopulation males have a fertilization advantage during sperm competition in the yellow dung fly (Scathophaga stercoraria).
Sexual conflict occurs whenever there is not strict genetic monogamy. The sexually antagonistic coevolution that potentially occurs because of this conflict involves adaptation by one sex followed by the counter-adaptation by the other, and may be thought of as an evolutionary arms-race. As a result of these cycles of antagonistic coevolution, females from one population may be less resistant t...
متن کاملThe Karyotype of the Yellow Dung Fly, Scathophaga stercoraria, a Model Organism in Studies of Sexual Selection
Knowledge of karyotypical characteristics of a species is essential for understanding how sexually selected and sexually antagonistic traits evolve. The yellow dung fly Scathophaga stercoraria L. (Diptera: Scathophagidae) is an established model system for studies of sexual selection and sexual conflict, but karyotypical data are lacking to date. Here, the karyotype of S. stercoraria was charac...
متن کاملA Review of the Natural History and Laboratory Culture Methods for the Yellow Dung Fly, Scathophaga stercoraria
The yellow dung fly Scathophaga stercoraria (L.) (Diptera: Scathophagidae) is a widespread and locally abundant fly associated with the dung of large mammals, especially farm animals. This species has recently become a standard test organism for evaluating toxic effects of veterinary pharmaceuticals in livestock dung. In this context, a review of its natural history and a general description of...
