From Wikipedia, the free encyclopediaJump to navigationJump to searchThis article is about the behavioural response. For the vehicle, see taxi. For other uses, see Taxi (disambiguation).
A taxis (plural taxes[1][2][3] /ˈtæksiːz/, from Ancient Greek τάξις (taxis), meaning ‘arrangement’[4]) is the movement of an organism in response to a stimulus such as light or the presence of food. Taxes are innate behavioural responses. A taxis differs from a tropism (turning response, often growth towards or away from a stimulus) in that in the case of taxis, the organism has motility and demonstrates guided movement towards or away from the stimulus source.[5][6] It is sometimes distinguished from a kinesis, a non-directional change in activity in response to a stimulus.
e.g.
- Thigmotaxis is the response of an organism to physical contact or to the proximity of a physical discontinuity in the environment (e.g. rats preferring to swim near the edge of a water maze). Codling moth larvae are believed to used thigmotatic sense to locate fruits to feed on.[23]
