The relative abundance of ship rats (Rattus rattus), Norway rats (R. norvegicus), and Pacific rats (R. exulans), was measured in four vegetation types on Stewart Island/Rakiura, over six consecutive seasons. Ship rats were found in all four vegetation types and dominated in podocarp-broadleaf forest and riparian shrubland. Norway rats were most common in(More)
Invasive species are often favoured in fragmented, highly-modified, human-dominated landscapes such as urban areas. Because successful invasive urban adapters can occupy habitat that is quite different from that in their original range, effective management programmes for invasive species in urban areas require an understanding of distribution, habitat and(More)
This study examined whether the diversity and relative abundance of ground-dwelling invertebrates changed in relation to type of vegetation cover. Invertebrate taxon diversity and relative abundance were assessed with pitfall traps placed under the native shrubs Olearia bullata and Coprosma propinqua, and in surrounding patches of exotic pasture. A total of(More)
The recent development of lightweight GPS collars has enabled medium-to-small sized animals to be tracked via GPS telemetry. Evaluation of the performance and accuracy of GPS collars is largely confined to devices designed for large animals for deployment in natural environments. This study aimed to assess the performance of lightweight GPS collars within a(More)
A range of distinctive dispersal features have been recognised within the New Zealand flora, and a wide range of fauna are involved in the dispersal of seed in New Zealand, either by consuming fruit or seed, or as transporters of adhesive seed. In this study the composition of New Zealand’s zoochorous fauna (except insects) was examined using both trait(More)
Understanding the influence of spatial scale on ecological processes that occur with exotic plant invasion can help us identify underlying mechanisms of successful invasion. Here we studied spatial associations between Thymus vulgaris invasion and plant community species richness, composition and abundance at multiple spatial scales. These scales included(More)
Private gardens collectively comprise the largest green space in most cities and the greatest potential for increasing the extent of wildlife-friendly and native-dominated habitat, improving the quality of ecosystem services, and providing opportunities for urban dwellers to reconnect with nature. Because attitudes and values driving landscape preferences(More)
Domestic gardens collectively cover substantial areas within cities and play an important role in supporting urban biodiversity and ecosystem functioning. The extent of their contribution to urban biodiversity is ultimately determined by the attitudes, motivations, and practices of their owners. We identified variables characterizing individual householders(More)
Because invasive species are often opportunistic and behaviourally flexible, they tend to be successful in urban landscapes, where they may use space differently than in their more traditional habitats. Consequently, control strategies developed for invasive pest species in non-urban areas may not succeed in an urban context. Using GPS tracking, we examined(More)
