1904. Recombination rate predicts inversion size in Diptera. Full Text available with Trip Pro

Recombination rate predicts inversion size in Diptera. Most species of the Drosophila genus and other Diptera are polymorphic for paracentric inversions. A common observation is that successful inversions are of intermediate size. We test here the hypothesis that the selected property is the recombination length of inversions, not their physical length. If so, physical length of successful inversions should be negatively correlated with recombination rate across species. This prediction (...) was tested by a comprehensive statistical analysis of inversion size and recombination map length in 12 Diptera species for which appropriate data are available. We found that (1) there is a wide variation in recombination map length among species; (2) physical length of successful inversions varies greatly among species and is inversely correlated with the species recombination map length; and (3) neither the among-species variation in inversion length nor the correlation are observed in unsuccessful

1906. Locomotion through use of the mouth brushes in the larva of Culex pipiens (Diptera: Culicidae). Full Text available with Trip Pro

Locomotion through use of the mouth brushes in the larva of Culex pipiens (Diptera: Culicidae). The larva of the mosquito Culex pipiens is a filter-feeder and is able to use the feeding current generated by its mouth brushes to glide slowly through the water. The hydrodynamics of the mouth brushes, and of gliding, were investigated by visualizing the feeding current using dyes. Unlike the mouth brushes of a sessile filter-feeder such as the blackfly larva, those of C. pipiens function more like

1908. Evolution of dosage compensation in Diptera: the gene maleless implements dosage compensation in Drosophila (Brachycera suborder) but its homolog in Sciara (Nematocera suborder) appears to play no role in dosage compensation. Full Text available with Trip Pro

Evolution of dosage compensation in Diptera: the gene maleless implements dosage compensation in Drosophila (Brachycera suborder) but its homolog in Sciara (Nematocera suborder) appears to play no role in dosage compensation. In Drosophila melanogaster and in Sciara ocellaris dosage compensation occurs by hypertranscription of the single male X chromosome. This article reports the cloning and characterization in S. ocellaris of the gene homologous to maleless (mle) of D. melanogaster, which
