klinokinesisKlinokinesis (ger.)

  • A form of kinesis in which changes of direction are more common the stronger the stimulus. For example, the flatworm (Dendrocoelum lacteum) increases its rate of turning as light intensity increases. Consequently it tends to spend less time in light places, and tends to form aggregations in dark places. (Oxford Dict. of Animal Behaviour 2006)

    We propose to divide kineses into (a) ortho-kineses (ὀρθόςdirect, forward)variations in linear velocity (previously called simply kineses); and (b) klino-kineses (κλίνεινto deviate)variations in angular velocity. The prefix klino- is free from anthropomorphic implication. The whole word klino-kinesis can be used to describe the kind of reaction discussed by Ullyott, as well as other ‘avoiding reactions’ and ‘phobo-taxes’ which have not yet been demonstrated to be either like or unlike it in their details.

    klinokinesis A change in rate of random movement of an organism (kinesis) in which the rate of change of direction (frequency of turning movements) varies with the intensity of the stimulus; cf. orthokinesis.
