Utilisation of the introduced New Zealand screwshell (Maoricolpus roseus) by native hermit crabs in eastern Tasmania - spatial variability in occupancy
Interactions between native and introduced species can help to elucidate the impact of exotic species on the broader community. This work examines utilisation of an introduced gastropod, the New Zealand screwshell (Maoricolpus roseus) by native hermit crabs in eastern Tasmania.
Samples of screwshells were collected from Bass Strait, Maria Island, Pirates Bay and Dennes Point using a modified scallop dredge or collected by divers. Site location, date, depth, dredge opening size were recorded, and random sub-samples of shells were measured for length and width, and spire damage was scored. Hermit crabs, if present, were identified to species, sexed and measured.
