A natural population of Drosophila melanogaster was sampled twice over a 5-year interval from the same French locality in the same season. Reaction norms of wing and thorax length and wing/thorax ratio, according to growth temperature (12-31 °C) were analysed in ten isofemale lines for each sample. Reaction norms were very similar between years, showing not(More)
Ten isofemale lines of Zaprionus indianus were analysed to study the reaction norms of five morphometrical traits (wing and thorax length, body weight, sternopleural bristle and ovariole number) in relation to growth temperature. All these traits exhibited nonlinear concave reaction norms and were characterized by the coordinates of their maximum: MV(More)
We examined the genetic architecture of plasticity of thorax and wing length in response to temperature in Drosophila melanogaster. Reaction norms as a function of growth temperature were analyzed in 20 isofemale lines in a natural population collected from Grande Ferrade near Bordeaux (southern France) in two different years. We found evidence for a(More)
Wild populations of Drosophila melanogaster were collected along a latitudi-nal transect between Ernaculum (10° latitude) and Jammu (32.4°). Altitudes were also highly variable, from sea level up to more than 2 000 m. The intensity of dark pigmentation on the thorax (trident) was estimated visually using four phenotypic classes, in flies grown at 17 and 25(More)
Natural populations of Drosophila kikkawai were collected in India and Sri Lanka, along a latitudinal transect ranging from 6.8 degrees to 31.8 degrees N latitude. Six morphometrical traits were analysed: wing and thorax length, body weight, ovariole number, and abdominal and sternopleural bristle numbers. Significant clines were observed for the three-size(More)
Immunotherapy represents a novel treatment approach for cancer; however, a longer maturation time and the lack of immunological markers are major obstacles in the development and characterization of immunological therapies. This study aims to identify gene expression profile on CD8+ T cells between the responder (completely regressed tumors) and(More)
To determine optimal and least effective response modes of learning disabled children, the procedure described by Owen, Braggio, and Ellen (1976) and the Illinois Test of Psycholinguistic Abilities were used. On the basis of pretest and posttest comparisons on selected subtests, the performance of these children could be described as individual or multiple(More)
