Bioacoustics offers new ways to monitor wildlife populations. Understanding vocal changes related to age can provide demographic data that are valuable but difficult to collect for threatened species. Here, we present the vocal signals of ontogeny an

Animal vocalisations can signify diverse behavioural contexts, knowledge of which can be applied in bioacoustic monitoring programs. Australia’s endemic black cockatoos (Calyptorhynchus sp., family Cacatuidae) are highly vocal species that are thre

Surveys in the native range of Japanese honeysuckle Lonicera japonica in Honshu, Japan, revealed a natural enemy biota attacking the plant that was rich in potential biocontrol agents for New Zealand (NZ), including 11 herbivorous insect species and

Ragwort flea beetle, released in New Zealand in 1983, successfully controls ragwort, except in regions that receive very high rainfall such as the West Coast of South Island. If biocontrol had not been instigated, expenditure on ragwort control acros

Many national schemes for setting priorities for invasive weed management have emphasized the current or future impacts of the weed more than the cost or feasibility of control, perhaps because the latter may be difficult to estimate. As part of a pr

Summary Biological control (biocontrol) can provide permanent cost-effective control of plant pests, but has variable success. The ability to predict the success of weed biocontrol should improve target prioritisation and the cost-benefit ratio of we

Surface electrical resistivity tomography (ERT) is recognized as a powerful non-invasive soil survey and monitoring method. Relationships between electrical resistivity (ER) and soil water contents that are needed to infer the spatial distribution of

The buddleia leaf weevil, Cleopus japonicus, was released in New Zealand in 2006 as a biological control agent for the weed Buddleja davidii. A two-phase open-field design was used to confirm laboratory host range and examine non-target impacts in th

A BSTRACT.— Reef fish movements over short and long time frames have important consequences for identifying essential fish habitat, quantifying ecological flows across the seascape and designing marine reserves. We use grunts (Haemulidae) as a repr

Contrary to predictions based on host-range testing, the gorse pod moth (GPM) infests pods of several exotic Genisteae and Loteae species, as well as the target weed gorse Ulex europaeus, throughout New Zealand. The original host-range tests were con
