Animal movement Choice chambers and mazes are often used in these experiments and woodlice and maggots are commonly the model animals A scientist called J. Cloudsley-Thompson carried out the first experiments on woodlouse behaviour One of his experiments focused on the response of woodlouse to humidity Algae that move towards the light to perform photosynthesis more effectively have a bigger chance of survival. All these behavioural strategies will increase the chances of woodlice or any other animal spending more time in favourable conditions (damp and mild temperature) than unfavourable ones (dry, extreme temperatures). . Speed and rate of direction turn increase, Woodlice display positive phototaxis. 6. \n'8 {GGG @* %X,45caq}W(0_uH9h\ ]*A ) Observe good hygiene procedures when handling invertebrates: do not eat or drink in the lab, wash hands with soap and water before leaving the lab, and cover any cuts or wounds. For the first experiment, the woodlice are added in the first transparent container that is half covered by black . The type of taxis is defined according to its originating stimulus. Choice chambers are an investigative method used to study animal behaviour and to determine the favoured conditions for a habitat. The humid and dark environment prevents them from desiccating (through water content loss from their skin surface) and allows them to hide from possible predators. A collection of experiments that demonstrate biological . The beetles move faster in the more humid environment; this will increase their chances of entering a less humid area, where they will slow down and tend to remain. Blue, moisture-indicating silica gel impregnated with cobalt(II)chloride (see CLEAPSS Hazcard) is TOXIC; the Hazcard suggests wearing gloves when handling large amounts, and avoiding any dust. 3. hb```b``Vb`a` @1XiKNBo];W|t%bjv TSqa~~FoL;%/f{`q%f A"g This could be a subject for further investigation.

Woodlouse display thigmokinesis, which is a movement response or lack thereof to contact stimuli. A sponge/ cotton wool/ filter paper soaked in water will reduce the risk of getting water on the platform itself when the choice chamber is moved. Unlike taxis, a kinesis response does not involve changing the direction of movement according to a stimulus direction but instead changing the organisms speed of movement and the rate of direction change. I remember doing this at school! Keep the woodlice to be used for the investigation in drier conditions for the 24 hours immediately beforehand. This response can be important when reacting to less directional stimuli like temperature or humidity and dont vary in space in clear gradients. Various aspects of their distribution, including the influence of soil pH are discussed. Set up an enclosed environment and divide it into interlinked compartments. This keeps the woodlice at a safe distance from the water and drying agent.
