are woodlice more attracted by a natural substrate than an artificial substrate?

condition one (y1): natural substrate (leaf 10cmx10cm)

condition two (z2): artificial substrate (paper 10cmx10cm)

control (c1): neither

a value of 1 indicates a choice of that condition. a value of 0 indicates a choice against that condition.

the choice of a condition is determined by the woodlouse spending >3 seconds in one condition

new set of woodlice

5 minutes then which condition they are in, using 9 woodlice
