Orthokinesis: How Movement Shapes Animal Behavior
Orthokinesis Introduction to Orthokinesis Orthokinesis represents a fundamental and relatively simple behavioral response observed across a diverse range of motile organisms, from microscopic bacteria to more complex invertebrates. It describes a change in an organism’s speed or rate of movement directly influenced by the intensity of a particular directional stimulus, rather than a directed movement […]
PHOTOTAXIS
Definition and Core Concepts of Phototaxis Phototaxis is defined formally as the directed locomotor movement of a motile organism, typically a bacterium, protozoan, or animal, either toward or away from a source of light. This fundamental behavioral response is critical for survival across countless species, linking the detection of electromagnetic radiation (light) directly to a […]
