Interactions
Land snail species like Vertigo ovata, Say, 1822, are crucial components to many ecological systems. Many organisms, such as some salamanders, birds, beetles, small mammals, and other snails rely on minute land snails for food source. Predatory organisms sometimes rely on the calcium carbonate in species like V. ovata as a significant source of calcium. Changes in the populations of these larger organisms can often be traced back to the land snails, which may be more greatly affected by environmental changes (Dourson, 2006).
