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). The experiment illustrates the type of choice chamber experiment which is possible to provide quantitative evidence of innate behaviour. Netting will be placed over the top so the woodlice can walk over it. Here's how to make your choice chamber for Harry the woodlouse. . As a result of this behaviour, woodlice tend to accumulate in crevices, between leaves or blades of grass, and under stones or fallen wood. An experiment lesson suitable for primary science or older that can be adapted or changed to use with maggots as well. 2 Position a lamp so that it illuminates the choice chamber and both sides are brightly lit. It could be interesting to establish which preference is stronger dark or damp. The direction of the stimulus determines the direction of the movement. 4. They prefer these as it allows them to hide from predators and prevent water loss through their skin. Another interesting difference between taxis and kinesis is that with: Woodlice are crustaceans often used as examples when investigating animal movement responses. Animals like woodlice are placed in these structures, and their behaviour is assessed by analysing their movement through these compartments. Woodlice. Other examples include the positive chemotaxis of some bacteria that will move into regions of higher glucose concentrations, an essential source of food. Developing an understanding of the statistical tests used to establish the significance level of the result of choice chamber investigations also requires an understanding of a null hypothesis. Be perfectly prepared on time with an individual plan. RSB teaching resources; Browse Nuffield teaching resources. This keeps the woodlice at a safe distance from the water and drying agent.
