In daylight, as in the dark, Ore-R males courted decapitated females very vigorously (Figure 6A).
In the heart of the Amazon rainforest in Brazil, giant diggers tear into the rock 24 hours a day to extract a dark grey ore rich in the iron on which every modern economy depends.
If olfactory or gustatory cues are not perceived by the male, latency till courtship initiation is considerable prolonged in the dark (compare Ore-R with Or83b2 or Poxn-pRes in Figure 4B).
Rust-colored chunks of ore, dark and irregular, jutted from the walls.
By contrast, the impairment of the male's olfaction by the Or83b2 mutation did not affect his courtship performance in the dark, as compared to Ore-R males (Figure 3), which suggests that the gustatory sense is sufficient to trigger courtship (M7) and elicit a high courtship vigor (M4).
There is a clearer sense of scale to a different image, taken above an aluminum plant in Darrow, La., where white foam flows through dry waste into an area submerged in water; both are tinted shades of dark red by bauxite, the ore that yields aluminum.
Misaíl grabs a dark and heavy rock from the soil: It's raw iron ore.
In the dark, the CI of Or67dGal4, as compared to that of Ore-R, males is slightly but significantly elevated (Figure S2C; p = 0.036), in apparent agreement with the published results [28].
The name sphalerite is derived from a Greek word meaning "treacherous," an allusion to the ease with which the dark-coloured, opaque varieties are mistaken for galena (a valuable lead ore).
Males impaired for visual tracking by the ninaB360d mutation or black paint covering their eyes all initiated courtship and as efficiently as Ore-R males, both in daylight and in the dark (Figure 2A).
