Description | Although land snails serve as food for many predators, rather little is known about the intensity of predation on land-snail populations and communities. The shell – being the main defence strategy against predation – needs to be interfered with by a predator for it to reach its prey. In a calcium-rich environment, snail shells persist for a long time and thus provide a valuable source of information in the form of the external and internal damage left by predators. These specific marks can be used to identify a particular predator, as well as to estimate predation pressure on snails. This approach allows us to easily reconstruct the food preferences of individual predators. |
