Orientation responses in animals

Orientation responses Relatively simple responses occur when abiotic/biotic factors are an issue = moving

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

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.

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.

Taxes Phototaxis – movement towards/away light. Chemotaxis – movement towards/away chemicals.

 Phototaxis – movement towards/away light. Chemotaxis – movement towards/away chemicals. Taxes Gravitaxis –

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.

Positive thigmotaxis – movement towards an object or movement that results from physical contact. Positive rheotaxis – movement against a current.

1. Activity – which one is what? Lice and fleas finding a nice, warm host. 2. Trout align themselves in an upstream position. 3. Snails moving up a pot. 4. Hedgehog moving away from sprayed weeds. 5. Photosynthetic organisms moving out of the shade. 6. Maggots moving towards dead meat. 7. Earwigs scurrying into a log.
