...Ádám Mészáros; György Kriska; Ádám Egri Mayflies are typically negatively phototactic during larval development, while their adults possess positive phototaxis. However, no extensive research was made about the wavelength dependence of phototaxis in any mayfly larvae. We measured the repellency...

... responses, however, depends on the relationship between cues when presented during trials, such as when cues are in accord or in conflict. For example, when light cues that elicit positive phototaxis conflicted with negative gravitaxis (light from below the monarch), monarch gravisensation was unaffected...

... these values? We explored this question in the context of phototactic behavior in larval zebrafish. We demonstrate that larval zebrafish use phototaxis to maintain environmental luminance at a set point, that the value of this set point fluctuates on a time scale of seconds when environmental luminance changes...

Making use of mutant lines, we show that these two behaviors are mediated by distinct groups of photoreceptors...

Furthermore, we report that closely related Allomyces species respond to either the chemical or the light stimuli presented in this study...

The directional bias may be due to light (phototaxis...

... spectrum for dark-adapted T. longicornis . The mean percentage (±s.e.m.) of positive phototaxis in five trials is plotted as a function of wavelength. Positive phototaxis was defined by an individual swimming into the chamber of a horizontal trough nearest to the light source during a 45 s light stimulus...

There is good evidence that location of mates by lampyrid beetles is achieved by a single spectral class of photoreceptor,whose spectral sensitivity...
