Context. House cats are increasingly suggested as having major ecological impacts in semiurban environments. Information on the activity of house is relatively scarce, especially habitats such wetlands. Aims. This study examines movement and foraging behaviour living periphery a wetland reserve Christchurch city, New Zealand. Methods. Twenty-one domestic suburban residential area were studied using radiotelemetry to determine home-range size, mean maximum distances travelled into adjacent...
Abstract Two methods for the determination of tetrodotoxin(TTX) in marine biota have been developed and validated using ultra-performance LC coupled to triple quadrupole MS. The direct analysis TTX is completed one method, while other method detects dehydration product after reaction with base. were a single-laboratory trial used test Paphies australis (pipi) samples collected from Whangapoua, New Zealand during April 2011. Pa. commonly eaten species bivalve that was found contain at levels...
Matauranga Maori, a knowledge system incorporating Maori philosophical thought, worldview and practice, provides important insight practice is vital for understanding managing Aotearoa New Zealand's ecosystems.Yet, until recently, it has remained largely invisible to mainstream ecologists resource managers in Aotearoa.Partnering with matauranga into ecological research offers an additional dimension neoclassical science, which we argue leads better outcomes society the environment.This...
Abstract The risks of vertebrate pesticides to non-target animals are determined by intrinsic susceptibility, the toxicokinetics compounds used, and degree frequency exposure. Metabolism persistence studies coupled with field surveys have provided us an improved understanding effects different anticoagulants. This has enabled choice tools for island versus mainland use in New Zealand, stimulated development low-residue tools. Brodifacoum is a potent second-generation rodenticide used...
Filtration by the freshwater mussel (Hyridella menziesi) population of Lake Tuakitoto (New Zealand) was modelled determining biomass, filtration capability, and proportion time spent filtering. The mean biomass in lake 12.3 g/m 2 AFDW, rate 32 mussels 1.9 L hr -1 g at 19-21°C, actively filtered for 93% time. It calculated that filters a volume water equal to once every hours, which represents an exponential grazing on phytoplankton 0.29/day. Mussel may account observed suppression...
Rodenticide and vertebrate pesticide registrations have declined worldwide over the last 30 years. New Zealand has not followed this trend, instead retaining essential toxins traps, improving their use exploring new mammal control tools. Looking to immediate future, as well continuing improve of existing tools, there are opportunities for further advances in emerging technologies such wireless technology species recognition aiding trapping programmes, self-resetting traps toxin-delivery...
Motivation to improve commercial fishing technology is changing from 'how can we catch more fish' reduce the impact of on environment'. To implement new fisheries technologies and innovations, it important have sources innovative ideas for improvement, processes allow uptake transition old technologies. One fishery that undergoing a New Zealand scampi (Metanephrops challengeri) fishery. Here report research programme aimed at improving cultural environmental performance practices, initiated...
Considerable effort has been put into retaining older vertebrate pesticides and improving the effectiveness safety of pest control. Nevertheless, conventional control targeting single species is sometimes still associated with non-target impacts, bioaccumulation toxins, fluctuating numbers, unexpected ecological consequences. To counter this, we are developing multi-species bait types for sustained field use that more palatable to species. We incorporating "low-residue" toxicants, namely...

Forest health can be adversely affected by invasive organisms. Biosecurity measures to prevent the establishment of harmful organisms at national points entry (e.g., airports or shipping ports) are vital protect forest health. Innovations in pest eradication technologies being developed based on their efficiencies and effectiveness. However, question whether people find them acceptable is rarely considered. In New Zealand, research underway into use highly targeted pesticide spraying using...
The ongoing use of 1080 toxin for the control mammal pests in New Zealand remains highly contentious. Several reviews over last 25 years identified information gaps and areas concern, both social scientific. In this paper these concern are discussed extensive scientific research that has been undertaken to clarify address them is reviewed. Although there a major national investment aimed at finding an alternative 1080, not yet fully achieved because low or inconsistent efficacy and/or...
Bait shyness is a significant threat to the sustainable control of vertebrate pests. New Zealand's foremost pest introduced brushtail possum (Trichosurus vulpecula). was identified in two wild populations by comparing consumption non-toxic bait types before and after each population presented with one containing toxin sodium monofluoroacetate (1080). Before poisoning, approximately 60% total type which 1080 later in, whereas poisoning this made up only 2-4% consumption. This persisted for at...
To manage brushtail possums (Trichosurus vulpecula) accurate estimates of abundance are essential Direct counts not feasible for large populations and index techniques normally employed A new technique estimating possum is the WaxTagreg; They potentially more effective than traps because they small easier to use very lightweight therefore higher numbers can be set out in field Whilst a national monitoring protocol WaxTagreg;s has been developed it important determine whether improvements...
The brushtail possum is a major agricultural and ecological pest in New Zealand. A novel noninvasive DNA sampling tool for detecting its presence (WaxTags, or WT) was tested. recovered from saliva left on WT, two lengths (407 bp 648 bp) of the cytochrome c oxidase I (COI) barcoding region were amplified by polymerase chain reaction (PCR). PCR products considered (+) when band clearly visible electrophoresis. Different factors that might affect investigated with captive possums: (i) both...
