| enhanced arbovirus surveillance with deep sequencing: identification of novel rhabdoviruses and bunyaviruses in australian mosquitoes. | viral metagenomics characterizes known and identifies unknown viruses based on sequence similarities to any previously sequenced viral genomes. a metagenomics approach was used to identify virus sequences in australian mosquitoes causing cytopathic effects in inoculated mammalian cell cultures. sequence comparisons revealed strains of liao ning virus (reovirus, seadornavirus), previously detected only in china, livestock-infecting stretch lagoon virus (reovirus, orbivirus), two novel dimarhabdov ... | 2013 | 24314645 |

| rhabdoviruses in two species of drosophila: vertical transmission and a recent sweep. | insects are host to a diverse range of vertically transmitted micro-organisms, but while their bacterial symbionts are well-studied, little is known about their vertically transmitted viruses. we have found that two sigma viruses (rhabdoviridae) recently discovered in drosophila affinis and drosophila obscura are both vertically transmitted. as is the case for the sigma virus of drosophila melanogaster, we find that both males and females can transmit these viruses to their offspring. males tran ... | 2011 | 21339477 |

| preliminary characterization of "sex ratio" and rediscovery and reinterpretation of "male sex ratio" in drosophila affinis. | in d. affinis "sex ratio" (sr), a form of meiotic drive characterized by the production of mostly or only female progeny by certain males, is associated with two different x chromosome sequences, xs-i xl-ii and xs-ii xl-iv. the behavior of the two sequences differed, depending on the y chromosome constitution, being either y(l) or 0. males with sequence xs-ii xl-iv and y(l) produced progenies with nearly normal sex ratios; males with the same x chromosome sequence but in the absence of a y chrom ... | 1972 | 5055127 |

| effect of island area on drosophila population densities. | species of the drosophila affinis subgroup show a positive correlation between population density and island area on islands in the vicinity of deer isle, maine. the low density of flies on small islands may be due to inbreeding depression, exposure to salt spray, desiccation, or decimation by violent storms. mushroom-feeding species of drosophila show great year to year fluctuations in abundance on these islands, probably due to changes in the level of their resource supply. population fluctuat ... | 1978 | 28309919 |
| the effect of light on the sexual behavior of drosophila affinis. | drosophila affinis is a species whose mating is facilitated by light. although sexually mature d. affinis males court d. affinis males and females vigorously in the light, they do not perform any of the courtship behaviors in the dark. this lack of courtship is not caused by the males and females being unattractive in the dark, since d. affinis males and females elicit high levels of courtship from drosophila melanogaster males in light and in darkness. fertility tests confirmed previous observa ... | 1987 | 3107541 |
| mitochondrial dna variation among the drosophila athabasca semispecies and drosophila affinis. | morphology, allozymes, and levels of postreproductive isolation indicate that the semispecies of drosophila athabasca are as recently diverged as typical populations within a drosophila species. however, levels of behavioral isolation, divergence in male mating song, and divergence in x-chromosome inversions suggest a much more ancient divergence. in this article, we have examined mitochondrial dna restriction site variation within and among the three semispecies. these data support the hypothes ... | 2016 | 7995924 |

| sex-ratio meiotic drive and y-linked resistance in drosophila affinis. | genetic elements that cheat mendelian segregation by biasing transmission in their favor gain a significant fitness benefit. several examples of sex-ratio meiotic drive, where one sex chromosome biases its own transmission at the cost of the opposite sex chromosome, exist in animals and plants. while the distorting sex chromosome gains a significant advantage by biasing sex ratio, the autosomes, and especially the opposite sex chromosome, experience strong selection to resist this transmission b ... | 2015 | 25571899 |
| ancestral polymorphisms in drosophila pseudoobscura and drosophila miranda. | ancestral polymorphisms are defined as variants that arose by mutation prior to the speciation event that generated the species in which they segregate. their presence may complicate the interpretation of molecular data and lead to incorrect phylogenetic inferences. they may also be used to identify regions of the genome that are under balancing selection. it is thus important to take into account the contribution of ancestral polymorphisms to variability within species and divergence between sp ... | 2011 | 21767458 |
| a multispecies approach for comparing sequence evolution of x-linked and autosomal sites in drosophila. | population genetics models show that, under certain conditions, the x chromosome is expected to be under more efficient selection than the autosomes. this could lead to 'faster-x evolution', if a large proportion of mutations are fixed by positive selection, as suggested by recent studies in drosophila. we used a multispecies approach to test this: muller's element d, an autosomal arm, is fused to the ancestral x chromosome in drosophila pseudoobscura and its sister species, drosophila affinis. ... | 2008 | 19061532 |
