Photokinesis - Wikipedia

https://en.wikipedia.org/wiki/Photokinesis
Photokinesis. Photokinesis is a change in the velocity of movement of an organism as a result of changes in light intensity. [1] The alteration in speed is independent of the direction from which the light is shining. Photokinesis is described as positive if the velocity of travel is greater with an increase in light intensity and negative if

Phototaxis - Wikipedia

https://en.wikipedia.org/wiki/Phototaxis
Middle: photokinesis involving changes in speed induced by changing light intensity. In patchy light environments, positive photokinesis results in accumulation in low light areas (and vice versa for negative photokinesis). Bottom: true phototaxis results in movement towards or away from a light source, but is not a response to a light gradient.

Photokinesis. Photokinesis entails modulation of swimming speed or turning frequency of an individual to match it to the ambient light intensity (Diehn et al. 1977; Nultsch and Häder 1988). The matched behavioural state remains constant and does adapt or habituate over ecologically relevant timescales, i.e. the time that the organism would

Phototaxis - an overview | ScienceDirect Topics

https://www.sciencedirect.com/topics/immunology-and-microbiology/phototaxis
Phototaxis is the process in which an organism alters its motility in response to light stimuli. This article focuses on phototaxis in photosynthetic bacteria and archaea, and the mechanisms and functions of photoreceptors and signal transduction chains.

https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-biology/phototaxis
Phototaxis is a photobehavioral response that involves the movement of an organism toward or away from a light source. Learn about phototaxis in Drosophila, Chlamydomonas, and other organisms, and how it is related to photokinesis and photoshock.

https://link.springer.com/chapter/10.1007/978-3-642-69767-8_47
Photokinesis describes the dependence of the speed of movement on the steady state light intensity, independent of the light direction. If the velocity at a given intensity is higher than in the dark control, photokinesis is called positive and if lower, negative. Some organisms do not move in darkness or in very bright light [13]. 3.

Photokinesis and Phototaxis Jesse Granger & Jason Dinh Photokinesis and Phototaxis are two ways animals can respond to light. Photokinesis is when an animal increases or decreases their activity levels in response to light, without orientation. For example, fiddler crabs freeze when a bright light shines on them. In contrast, some fish swim

photokinesis A change in the speed of locomotion (or frequency of turning) in a motile organism or cell which is made in response to a change in light intensity. The response is unrelated to the direction of the light source. Compare phototaxis. Source for information on photokinesis: A Dictionary of Ecology dictionary.

What is Phototaxis? What is Positive and Negative Phototaxis?

https://onlyzoology.com/what-is-phototaxis-what-is-positive-and-negative-phototaxis/
In simple words, Phototaxis is called negative if the movement is away from the direction of the increasing light intensity. It has been noticed that Negative phototaxis can be only observed in larval Drosophila melanogaster within the first three developmental instar stages. On the other hand, adult ones can display Positive phototaxis very well.

Illustration of dark photokinesis as a non-directional mechanism for light seeking. A: Larvae within an arena are suddenly exposed to complete darkness and are blocked from view of a distant light source. Activity rapidly increases in the dark (dark photokinesis) enabling larvae to eventually escape the arena.

The Amblyopsid cavefishes, family Amblyopsidae, have been viewed as a model system for studying the ecological and evolutionary processes of cave adaptation because the four cave-restricted species in the family represent a range of troglomorphy that reflect variable durations of isolation in caves (Poulson 1963, Poulson and White 1969).
