ECOLOGY OF SHIP RATS (RATTUS RATTUS)INAKAURI
Summary: Home range dimensions and habitat use by ship rats (Rattus rattus) atPuketi, a kauri (Agathis australis) forest in Northland, were examined by live capture and radio-tracking over five weeks in September and October 1993. Home ranges of six females and five males averaged 0.86 ha in area an...
