摘要

Sand hoppers (Amphipoda: Talitridae) are semiterrestrial crustaceans that feed upon stranded kelp. Their burrowing behaviour plays an important role in reintroducing nutrients into the sediment. The most abundant sand hopper on New Zealand's beaches is iTalorchestia iquoyana Milne-Edwards, 1840. It is host to a parasitic mermithid nematode, iThaumamermis izealandica Poinar, Latham and Poulin, 2002, which invariably kills its sand hopper host by emerging to complete its maturation and reproduction in a moist sand environment. The aim of the present study was to assess if the burrowing behaviour of iTa. quoyana showed pathologic consequences of infection by iTh. zealandica. Two experiments were conducted to assess temporal variation in sand hopper burrowing in vitro. Parameters measured included the hour after sunrise and sunset that sand hoppers first emerged and the number of surface visits in the first hour after emergence.
