Orientation responses in animals
Orientation responses Relatively simple responses occur when abiotic/biotic factors are an issue = moving the animal away from the unfavourable condition. Taxes and Kineses (both innate).
Orientation responses Relatively simple responses occur when abiotic/biotic factors are an issue = moving the animal away from the unfavourable condition. Taxes and Kineses (both innate). More complex may occur over a long distance to a predetermined location out of sensory contact. Homing and migration (both innate).
Taxes Movement away or towards external stimulus.
Taxes Movement away or towards external stimulus. Response = directional.
Movement away or towards external stimulus. Taxes Response = directional. Tactic responses are named according to the kind of stimulus (light, heat etc) ad the direction. Positive =towards, negative = away.
Taxes Phototaxis – movement towards/away light. Chemotaxis – movement towards/away chemicals.
Phototaxis – movement towards/away light. Chemotaxis – movement towards/away chemicals. Taxes Gravitaxis – movement towards/away from gravity. Thermotaxis – movement towards heat.
Phototaxis – movement towards/away light. Chemotaxis – movement towards/away chemicals. Taxes Gravitaxis – movement towards/away from gravity. Thermotaxis – movement towards heat. Positive thigmotaxis – movement towards an object or movement that results from physical contact.
Phototaxis – movement towards/away light. Chemotaxis – movement towards/away chemicals. Gravitaxis – movement towards/away from gravity. Taxes Thermotaxis – movement towards heat. Positive thigmotaxis – movement towards an object or movement that results from physical contact. Positive rheotaxis – movement against a current.
