Most studies focus on fast-spreading invasive species with high impacts, whilst invasive species with restricted distributions tend to be neglected in the ecological literature. The New Zealand gastropod, Zeacumantus subcarinatus, introduced into the

Meta-analyses of disparate studies suggest that size and age of a 'no-take’ area (marine sanctuary) can influence its ecological response to protection. Few studies, however, have been designed explicitly to test how these factors influence the abu

Reviews of global studies suggest that even small no-take marine protected areas (MPAs) can have localized benefits on harvested organisms of varying mobility. The generality of this conclusion, however, has been questioned due to poor experimental d

An investigation of the impacts from elevated intertidal Pacific oyster culture in a New Zealand estuary showed enhanced sedimentation beneath culture racks compared with other sites. Seabed elevation beneath racks was generally lower than between th

Caulerpa taxifolia was first discovered in New South Wales, Australia, in April 2000 and is now present in nine waterways. Infestations, which range from sparse distributions of scattered runners to dense beds 40 cm thick, covered approximately 8.1 k

The dispersion patterns and feeding behaviour of intertidal whelks were investigated in north‐eastern New Zealand. Aggregations of whelks feeding on clams occurred regularly, with an average of 15–20 individuals per aggregation. Death of clams wa

The spatial and temporal variability in density and distribution of mussel larvae and spat associated with bottom-drifting algae was investigated at Ninety Mile Beach, northern New Zealand, between October 1998 and April 2000. Analyses of plankton to

Summary Unequal sex ratios favouring males, especially in younger or smaller animals, is a feature of many infaunal bivalve species, including geoducks. Size and age at sexual maturity, sex ratios, and growth rates of the New Zealand geoduck, Panopea

The sediment record of Whangape Harbour shows that there were significant fluctuations in depositional energy in the harbour during the period from c >8000 cal yr B P to some time within the last millenium, and that fluvial influences increased as th

The native fucalean macroalga Carpophyllum flexuosum (Esper) Grev. has recently occupied many reefs on wave‐exposed coasts in north‐eastern New Zealand. At recently colonised sites, C. flexuosum occurs mainly on coralline‐dominated areas with m
