Improving detection probabilities for vertebrate pest management
Applications are sought for a PhD project at the University of Auckland in collaboration with Landcare
Research focussed on pest mammal behavior and interactions with control devices in relation to
maximizing detection probabilities. This PhD is part of a larger programme of research funded by the
Foundation of Research Science and Technology aimed at improving the cost-effectiveness of both aerial
and ground-based control and eradication of mammal pests for the protection of New Zealand’s
indigenous biota and livestock health.
Effective pest control requires animals to engage and interact with devices such as baits, bait stations,
and traps. The probability of a pest engaging with a device can be modelled as a detection function and
used to determine the effect that pest density, lures and device spacing has on encounter and
interaction probabilities. Research will be built around investigating the partitioning of Pd (probability of
detection) into its constituent components of Pe (encounter) and Pi (interaction), and how these
probabilities can be manipulated to improve pest control efficacy. Research will combine fieldwork on
the ecology and behaviour of different pest species with statistical sampling and modelling. Fieldwork
will involve empirical testing of model predictions of optimum landscape distribution of devices, device
and bait/lure design, using monitoring devices including GPS collars, contact loggers and infra-red
activated cameras.
The successful applicant will be supervised by Dr James Russell at the University of Auckland and Bruce
Warburton at Landcare Research, Lincoln. Fieldwork will be conducted in collaboration with Landcare
Research at various field sites around New Zealand. The student will have scope in selecting fieldwork
locations, methods, and the species of interest in consultation with supervisors. The project will be
suited to a student with interests in statistics, fieldwork, pest control and mammal biology. The
University of Auckland is New Zealand’s leading research university and Landcare Research is New
Zealand’s foremost terrestrial environmental research organization. Expected start date is early 2011.
The position will remain open until filled, but for strongest consideration applications (CV, university
grades and 2-3 references) should be received before Oct 31 2010.
