wildlife crime scene investigation techniques tools and technology
Endangered Species Research, 2009Co-Authors: J E Cooper, Margaret E Cooper, Paul BudgenAbstract:Wildlife crime, defined here as the illegal taking, disturbance, possession, trade or Movement of Animals and or their derivatives, is a growing international problem that threatens the survival of many species. In the investigation of such incidents the ‘crime scene’ may range from the carcass (or parts) of an animal to terrain that encompasses topography as varied as forest or desert and which may include diverse natural and man-made structures. often, the location of the wildlife crime scene is isolated, with few facilities for proper investigation and collection of evidence. In poorer parts of the world and in countries experiencing social unrest, these features may present particular challenges. Wildlife crime scene work is such that equipment, investigative techniques and scientific technology all need to be appropriate to, and the best available in, the circumstances. Effective investigation under field conditions is likely to require a combination of portable and easy-to-use laboratory equipment coupled with modern methods of data collection and information transmission. An interdisciplinary approach is essential. Biologists/naturalists and those experienced in health studies, especially epidemiology, can often usefully complement the role of the police, enforcement officials and crime scene specialists.

Legal and ethical aspects of new wildlife food sources
Biodiversity and Conservation, 1995Co-Authors: Margaret E CooperAbstract:The production of Animals for new sources of food may be affected by a variety of laws relating to the keeping, trading, health, welfare and Movement of Animals. Other legislation, such as that applicable to wildlife and to human safety, are also relevant. Religious, cultural and ethical considerations may also influence attitudes towards a new food product. It is important that these factors are taken into account during the planning and progress of an enterprise since they may have a substantial impact on its viability.

biosecurity interceptions of an invasive lizard origin of stowaways and human assisted spread within new zealand
Evolutionary Applications, 2013Co-Authors: David G Chapple, Anthony H Whitaker, Stephanie N J Chapple, Kimberly A Miller, Michael B ThompsonAbstract:Globalization, and the resultant Movement of Animals beyond their native range, creates challenges for biosecurity agencies. Limited records of unintentional introductions inhibit our understanding of the trade pathways, transport vectors and mechanisms through which hitchhiker organisms are spread as stowaways. Here, we adopt a phylogeographic approach to determine the source and human-mediated dispersal pathways of New Zealand's only invasive lizard, the delicate skink (Lampropholis delicata), intercepted by biosecurity agencies in New Zealand. Biosecurity agencies correctly predicted the source region of 77% of stowaways, which were usually solitary adults, arriving via air or sea pathways during the cooler months, evading initial border checks and alive when detected. New arrivals from Australia comprised 16% of detections originating from the region between Brisbane and Sydney. Our analyses indicate human-mediated dispersal has driven the post-border spread of L. delicata within New Zealand. Propagule pressure was substantially greater for L. delicata compared with the noninvasive, congeneric Lampropholis guichenoti. Our results highlight the transport pathways, spread mechanisms, and stowaway characteristics of Lampropholis lizards entering New Zealand, which could enhance current biosecurity protocols and prevent the establishment of additional lizard species.

Medieval animal management practices at Proezzhaia I: Insights from dietary stable isotope analysis
Journal of Archaeological Science: Reports, 2018Co-Authors: Lacey S. Fleming, Robert J. Losey, Tatiana Nomokonova, Sandra Garvie-lok, Artur Kharinskii, E. V. KovychevAbstract:Abstract In this paper, we report the stable carbon and nitrogen isotope analysis results of wild (n = 15) and domestic (n = 21) animal samples from the Proezzhaia I site, a fortified Medieval settlement in Trans-Baikal, Siberia. Additionally, we analyzed five modern freshwater fish samples from the Shilka River, which flows immediately north of the site. Together, these samples provide the first dietary stable isotope data for the entire Trans-Baikal region. Our results reveal a C3 plant dominated diet for all animal taxa sampled, but with a possible minor inclusion of C4 plant material in the diets of some cattle (Bos sp.) and horses (Equus sp.). We infer this C4 plant was likely a type of millet, the remains of which were identified at a contemporaneous site upriver. Additionally, these results indicate that some cattle and horses consumed plant material grown in 15N-enriched soil, which suggests several distinct animal management practices, or may indicate a trade in or Movement of Animals from an area with a different nitrogen isotope baseline.
