Quiller Publishing Ltd Stalking Fallow
Stalking Fallow is an extensive guide to the challenge of management and techniques of stalking fallow deer. It has been written not only with the novice and experienced stalker in mind, but also the deer manager and landowner. There is also much to learn if you simply stalk deer with a camera. Thornley provides a unique insight into how to stalk woodland and open ground and the techniques in the use of using high seats. It also highlights the risks involved for the stalker as well as the deer. Managing the population, dealing with crop damage, arranging and participating in collaborative team culls are all covered for those faced with a wider management responsibility where large populations of fallow exist. This definitive guide is essential reading for all associated with the management of fallow deer.

CABI Publishing Grassland Dynamics: An Ecosystem Simulation Model
The development of computer simulation models is an important growth area in both pure and applied ecology. The opportunity that mathematical models provide to integrate the components of an ecosystem, results in the ability to make quantitative predictions about the future behaviour of that system, or of elements within it. This means that they are powerful tools with wide applications and enormous potential for increasing our understanding of natural systems and our ability to use them in a sustainable way. This book is, almost uniquely, a complete account of one such model, the Hurley Pasture Model, a dynamic, deterministic, mechanistic simulation model for grassland, which has been developed by the author over some twenty years, in collaboration with scientists at several centres. Firstly, the rationale and theoretical elements of this type of model are described. An overview of the Hurley grassland simulator and the derivation and construction of its plant, animal, soil and litter, water, and environment and management components is then given. Next, the model is evaluated by a series of long and short-term dynamic simulations and steady state responses, which demonstrate how predictions can be made about the effects of, for example, climate change or particular regimes of fertilizer application, grazing or cutting. This book will be of great value to grassland agronomists and modellers, crop physiologists and plant ecologists, and to students of ecology as a case study of a plant ecosystem model. It will also be of interest to other ecologists and environmentalists and those in the field of computer modelling and its applications.

CABI Publishing Mathematical Models in Agriculture: Quantitative Methods for the Plant, Animal and Ecological Sciences
Bringing together the disciplines of agriculture, animal science, plant science and ecology, this book explores how mathematics can be used to understand and explain agricultural processes. It starts by providing a review of the mathematical models currently available to agriculturalists, and the philosophy behind, and objectives of, modeling. The book then applies these techniques to real-life problems faced by people managing crops and animals, including the influence of digestion on animal growth rates and levels of photosynthesis on crop yield.
