Drosophila Embryogenesis Scales Uniformly across Temperature in Developmentally Diverse Species (original) (raw)
Figure 4
Drosophila species develop at different rates and respond to temperature in distinct ways.
(A) Images of developing embryos of each species are shown to scale. All species go through the same stages in the same order at all viable temperatures. (B) At 17.5°C all species show uniformly long developmental times, with D. virilis and D. mojavensis being significantly longer than other species. (C) At 22.5°C and (D) 27.5°C there is considerably more variation between species. While developmental times decrease with increasing temperature across all species, the effect is muted in the alpine species. (E) At 30°C, developmental rate has stopped accelerating and the alpine species are seeing considerable slow-down in development time.
