Low evolutionary potential for egg-to-adult viability in Drosophila melanogaster at high temperatures.
To cope with the increasing and less-predictable temperature forecasts under climate change, many terrestrial ectotherms will have to migrate or rely on adaptation through plastic or evolutionary means. Studies suggest that some ectotherms have a limited potential to change their upper thermal limits via evolutionary shifts, but research has mostly focused on adult life stages under laboratory ...
متن کاملModes of Selection Maintaining an Inversion Polymorphism in DROSOPHILA PAULISTORUM.
The possibility that fitness relationships associated with an inversion polymorphism in D. paulistorum were frequency dependent was investigated. Using allozymes of tetrazolium oxidase to mark inversions, the effects of genotype frequency, larval density, and culture conditions on fitness were assessed. The proportions of genotypes among egg-laying females were varied, thus changing the expecte...
متن کاملContinued Neurogenesis in Adult Drosophila as a Mechanism for Recruiting Environmental Cue-Dependent Variants
BACKGROUND The skills used by winged insects to explore their environment are strongly dependent upon the integration of neurosensory information comprising visual, acoustic and olfactory signals. The neuronal architecture of the wing contains a vast array of different sensors which might convey information to the brain in order to guide the trajectories during flight. In Drosophila, the wing s...
متن کاملEvaluating Animation as a Mechanism for Maintaining Peripheral Awareness
Animation is becoming increasingly used to communicate information within some limited viewing area. Little is known, however, about the eeectiveness and the possible distractions of animation used in this way. This article describes an initial experiment exploring the information awareness and distraction capabilities of diierent styles of animation.
متن کاملGood Genes and Sexual Selection in Dung Beetles (Onthophagus taurus): Genetic Variance in Egg-to-Adult and Adult Viability
Whether species exhibit significant heritable variation in fitness is central for sexual selection. According to good genes models there must be genetic variation in males leading to variation in offspring fitness if females are to obtain genetic benefits from exercising mate preferences, or by mating multiply. However, sexual selection based on genetic benefits is controversial, and there is l...
