Readiness is controlled by the level of light adaptation, which alters the thresholds for behavioral responses to light stimuli.
Although much is known about the effects of intense light exposure on basic visual processing (see Barlow, 1972, and Hood and Finkelstein, 1986, for reviews), less is known about how light adaptation affects task performance.
Remarkably, the dimensions of the window depend upon the level of light adaptation when tested in a light system that simulates the natural ALD (Forward, 1989b).
plebs have been shown to migrate upon light adaptation at 0 [degrees]C as well as in the absence of light when the temperature is raised 10 [degrees]C (Meyer-Rochow and Tiang, 1979), we also tested the effect that light adaptation and a 4 [degrees]C temperature increase (to 7 [degrees]C) in the dark had on irradiance sensitivity and temporal resolution.
For complete reduction in light intensity, the proportion of copepods exhibiting an escape response varied with the light adaptation intensity.
