WEEK 5Dan’s Section – BIEB 166 – Dr. NiehWed. 5 – 5:50 PM @ CSB 004OH: Wed 3 – 4 PM @ York 3010 ALecture 10: Kinesis and TaxisI. Kinesis – undirected orientation movements1. Paramecium: Moves faster in warm, salty water in no specific direction2. Human Body Louse: Moves randomly and then slows when reaching a warm areaII. Taxis – Directed orientation movements directed with respect to a stimulus1. phototaxis: with respect to lightEx)Bees, fly maggot, fungus (not an animal)2. phonotaxis: with respect to soundEx) Crickets3. Chemotaxis: with respect to chemicalEx) Amoeba, snake4. Menotaxis: Maintaining a constant angleEx) silk moths5. Mnemotaxis: landmark orientationEx) salmon, surfing6. Magnetotaxis: magnetic cuesEx) Homing pigeon, humpback whale7. Klinotaxis: successive sampling while moving through a gradientEx) fly maggot8. Tropotaxis: simultaneous samples frompaired receptorsEx) ants, bees9. Teleotaxis: fixation on a distant stimulusEx) Archerfish, water monkey, pray. MantisHelp with meno and mnemo: Mean anglerfish pushed Nemo onto land.
