Quantifying Diets of Wildlife and Fish: Practical and Applied Methods

Quantifying Diets of Wildlife and Fish presents different techniques available to study animal diets. Ecologists determine animal diets to build natural history knowledge, test hypotheses in ecological theory and make informed management decisions for important ecosystems. Many researchers use techniques traditionally applied to the animals they study, rather than choose from the techniques with greatest potential for their study. In an effort to encourage researchers to consider new approaches, this book focuses on the techniques, rather than on particular groups of organisms or specific environments. With contributions from leading ecologists, chapters explore experimental design, observational techniques (including new technologies), stomach contents and faecal analysis, eDNA, tracers and stable isotopes. They also cover the latest multivariate methods of analyses suitable for describing animal diets and feeding relationships, as well as testing hypotheses relevant to ecological theory, environmental management and biological conservation. The expert knowledge provided will encourage readers to look beyond the boundaries of their specialties, assist in testing important hypotheses and provide insights into management problems. The examples in this book cover a range of vertebrates and invertebrates, as well as different environments, to open these methods up for novice ecologists and stimulate lateral thinking in more experienced researchers.

Emeritus Professor Michael Calver is based in the School of Environmental and Conservation Sciences, as well as the Centre for Terrestrial Ecosystem Science and Sustainability in the Harry Butler Institute at Murdoch University. Michael describes himself as a frustrated ecologist who, despite earning his PhD in entomology, soon discovered that prospective research students were more interested in the kind of animals that view insects as food.

Emeritus Professor Neil Loneragan is based in the School of Environmental and Conservation Sciences and the Harry Butler Institute at Murdoch University and is an adjunct Professor at IPB University in Indonesia. His interests lie in understanding marine and estuarine food webs, fisheries dynamics and the application of ecological principles to evaluating fish stock enhancement and marine ranching.
