| This suggests that the fusion of response observed in geotaxis and phototaxis also exists in more sophisticated forms of navigation. |
|
| It therefore seems that positive phototaxis was stronger than the positive geotaxis as a driving force of cell motility. |
|
| Groups of Hies are introduced into the top of the cylinder, where they remain temporarily due to their natural propensity for negative geotaxis. |
|
| They cause a variety of behavioral phenotypes including overall sluggishness and abnormal phototaxis, geotaxis, flight ability, ether recovery, and mating vigor. |

|
| No differences in aluminum-exposed animals were observed with respect to surface righting, negative geotaxis or activity in an open field. |
