New insights into wild deer population genetics, ecology and impacts : implications for management in south eastern Australia

This thesis is a compilation of my own work, driven by my interest into the ecology and impacts of introduced deer in Victoria. My interest in deer initially lead me to undertake an honours project, focussed on deer as a vector for parasites that can affect domestic livestock. During my honours year it became apparent that little was known about the ecology of wild deer throughout south east Australia. My PhD study was therefore developed to fill knowledge gaps of deer ecology, with a focus on developing and optimising ecological tools to generate data to improve deer management strategies. There are many methods available which can be used to collect ecological data on invasive species, such as deer. For my study, I chose methods from four quite discrete fields; global positioning systems (GPS) tracking, population genetics, camera trapping and spatial modelling. These methods were chosen as they are commonly used in ecological studies of invasive species. During my candidature significant attempts were made to deploy GPS collars onto sambar deer to investigate their movement patterns. Movement pattern data is extremely useful and can provide insights into habitat preferences, dispersal ability and other information useful for management. Significant time (around 12 months) was spent applying for ethics approval, gaining relevant approvals, permits and licenses to perform this work as well as performing collaring attempts. Unfortunately all attempts were unsuccessful and the investigation of sambar deer movement patterns had to be abandoned. This highlights the difficulties of working with cryptic deer species inhabiting difficult terrain. The other fields of research pursued (population genetics, camera trapping and spatial modelling) were more successful, the results of which are presented and discussed in this thesis. As the three methods employed in this study are taken from very different fields, a number of experts were enlisted to guide the respective data chapters. The population genetic studies (Chapters two and three) were guided by my primary supervisor Dr Fiona Hogan. I conducted all scat collections from across Victoria, including French Island and Mount Cole and performed all DNA isolations (over 300 in total). Population structure analysis for chapter three was undertaken with the assistance of Dr Faye Wedrowicz and Dr Carlo Pacioni. The camera trapping study (Chapter four) involved deploying camera traps in Baw Baw National Park, which I conducted myself. Occupancy and detectability data analysis for chapter four was performed with the assistance of Dr Hugh Davies. Spatial modelling (Chapter five) which focussed on modelling deer-vehicle collision risk across Victoria was directed by Dr Casey Visintin. Chapter’s two to five are written as independent scientific publications, therefore there is some unavoidable repetition within the thesis as a whole. Minor changes have been made to the formatting of the published papers to keep style consistent within the thesis.Doctor of Philosoph

Target and Non-Target Approaches for Food Authenticity and Traceability

Over the last few years, the subject of food authenticity and food fraud has received increasing attention from consumers and other stakeholders, such as government agencies and policymakers, control labs, producers, industry, and the research community. Among the different approaches aiming to identify, tackle, and/or deter fraudulent practices in the agri-food sector, the development of new, fast, and accurate methodologies to evaluate food authenticity is of major importance. This book, entitled “Target and Non-Target Approaches for Food Authenticity and Traceability”, gathers original research and review papers focusing on the development and application of both targeted and non-targeted methodologies applied to verify food authenticity and traceability. The contributions regard different foods, among which some are frequently considered as the most prone to adulteration, such as olive oil, honey, meat, and fish. This book is intended for readers aiming to enrich their knowledge through reading contemporary and multidisciplinary papers on the topic of food authentication

Búsqueda de materia oscura en experimentos de búsqueda directa DAMIC

ABSTRACT: The framework of this work is the DAMIC-M Experiment and its proof-of-concept LBC (DAMIC-M stands for DArk MAtter in CCDs, while LBC for Low-Background Chamber). The purpose of DAMIC-M is search for Dark Matter (DM) particles by detecting nuclear or/and electrons recoils induced by light mass Dark Matter. A crucial part of this goal is a detailed knowledge of the backgrounds noise and particle identification. The understanding of this has been the main aim of work in this thesis, which can be summarized as: i) validation of DAMICG4, a tool used to simulate the interactions of particles in matter based on Monte Carlo simulations; ii) validation of psimulCCDimg, a software used to mimic the response of the DAMIC-M detector; iii) create a data base of simulated particles of different nature (mainly alpha, muons and electrons) which are used in other two Works focused on machine learning algorithm.RESUMEN: Este trabajo está enmarcado en el Experimento DAMIC-M y su prototipo LBC (DAMIC-M es un acrónimo para DArk MAtter in CCDs at Modane, mientras que LBC son las siglas para Low Background Chamber). El propósito de DAMIC-M es la búsqueda de partículas de Materia Oscura mediante la detección de los retrocesos nucleares y/o de electrones inducidos por Materia Oscura ligera. Una parte crucial para este objetivo es un conocimiento detallado de los ruidos de fondo y la identificación de partículas. La comprensión de estos ha sido el principal objetivo de este trabajo, el cual puede resumirse en: i) validación de DAMICG4, una herramienta utilizada para la simulación de las interacciones entre partículas y materia mediante simulaciones Monte Carlo; ii) validación de psimulCCDimg, software utilizado para emular la respuesta del detector de DAMIC-M; iii) creación de una base de datos de partículas simuladas de diferente naturaleza (principalmente alfas, muones y electrones) que será utilizada en otros dos trabajos dedicados al desarrollo de un algoritmo de machine learning.Grado en Físic

A Validation Assessment of THUNDER 6.5\u27s Intelligence, Surveillance, and Reconnaissance Module

A validation assessment of THUNDER 6.5\u27s Intelligence, Surveillance, and Reconnaissance (ISR) module is accomplished using formulational and experimental validation techniques. A comparison of ISR purposes and processes according to military doctrine is made with the purposes and processes of ISR implemented within THUNDER 6.5. This comparison provides an overview of the process, an understanding of the level of aggregation within THUNDER, insight into possible problem areas in THUNDER, and a basis for improving THUNDER ISR processes. Sensitivity analysis of the ISR parameters as they relate to the Quality, Quantity, and Timeliness of ISR is also presented to provide insight into the responsiveness of THUNDER to changes in ISR capability for selected battle outcomes. Linear Regression and a Face-Centered Central Composite Design were used to generate a response surface. Ninety-percent confidence intervals were used to determine differences in mean response among the full factorial design points
