nails live in a variety of soil types and changes in soil structure due to human activity are common. In this experiment, we tested the preference of a soil-associated snail (Anguispira alternata) to soils with different organic matter content (simulating the addition of compost or the loss of organic matter in urban soils). Six soil mixtures were randomly assigned within a plastic ‘shoe box’ divided into six compartments, using plastic dividers that extended to just below the soil surface. Six replicates were created and two snails were placed in each compartment, for a total of 72 snails. Equal-sized pieces of lettuce were placed at the soil surface in each compartment. To collect data the number of snails in each compartment were counted and a chi square test was conducted to analyze the data. It was found that the snails avoided the two sandiest compartments and did not distinguish between the four compartments with higher or equal concentrations of coconut fiber.
