Do not use forceps as this may cause harm to them. 4. endstream endobj startxref . After a fixed time, compare the difference between the distribution you would expect if the null hypothesis were true (woodlice distributed 50:50 between damp and dry areas) and the distribution achieved in the laboratory. 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. For example, a null hypothesis might state 'Woodlice show an equal preference for damp and dry areas in the choice chamber'. The woodlice will be introduced into choice chambers which are half damp and half dry and allocated a period of time before counting how many have settled in each area. The direction of the stimulus determines the direction of the movement.
