Non-African populations of Drosophila melanogaster have a unique origin.
Drosophila melanogaster is widely used as a model in DNA variation studies. Patterns of polymorphism have, however, been affected by the history of this species, which is thought to have recently spread out of Africa to the rest of the world. We analyzed DNA sequence variation in 11 populations, including four continental African and seven non-African samples (including Madagascar), at four ind...
متن کاملChromosomal patterns of microsatellite variability contrast sharply in African and non-African populations of Drosophila melanogaster.
Levels of neutral variation are influenced by background selection and hitchhiking. The relative contribution of these evolutionary forces to the distribution of neutral variation is still the subject of ongoing debates. Using 133 microsatellites, we determined levels of variability on X chromosomes and autosomes in African and non-African D. melanogaster populations. In the ancestral African p...
متن کاملToxicological Evaluation of a New Lepidopteran Insecticide, Flubendiamide, in Non-Target Drosophila melanogaster Meigen (Diptera: Drosophilidae)
Background: Flubendiamide, comparatively a new pesticide designed to eradicate lepidopteran insect pests is known to have low risk to birds, mammals, fish, algae, honey bees, non-target arthropods, earthworms, soil macro- and micro-organisms, non-target plants as well as sewage treatment organisms; however, the risk assessment for aquatic invertebrates from metabolite could not be finalized wit...
متن کاملSleep in populations of Drosophila melanogaster Sleep in populations of Drosophila melanogaster
15 The fruit fly Drosophila melanogaster is a diurnal insect active during the day with 16 consolidated sleep at night. Social interactions between pairs of flies have been shown to 17 affect locomotor activity patterns, but effects on locomotion and sleep patterns have not been 18 assessed for larger populations. Here, we use a commercially available Locomotor Activity 19 Monitor (LAM25H) syst...
متن کاملAfrican Drosophila melanogaster and D. simulans populations have similar levels of sequence variability, suggesting comparable effective population sizes.
Drosophila melanogaster and D. simulans are two closely related species with a similar distribution range. Many studies suggested that D. melanogaster has a smaller effective population size than D. simulans. As most evidence was derived from non-African populations, we readdressed this question by sequencing 10 X-linked loci in five African D. simulans and six African D. melanogaster populatio...
