Earth surface processes, landforms and sediment deposits are intimately related - involving erosion of rocks, generation of sediment, and transport and deposition of sediment through various Earth surface environments. These processes, and the landforms and deposits that they generate, have a fundamental bearing on engineering, environmental and public safety issues; on recovery of economic resources; and on our understanding of Earth history. This textbook brings together the traditional disciplines of sedimentology and geomorphology to explain Earth surface processes, landforms and sediment deposits in a comprehensive and integrated way. It is the ideal resource for a two-semester course in sedimentology, stratigraphy, geomorphology, and Earth surface processes from the intermediate undergraduate to beginning graduate level. The book is also accompanied by a website hosting illustrations and material on field and laboratory methods for measuring, describing and analyzing Earth surface processes, landforms and sediments.

The microscopic soil and plant nematodes that are parasitic on crop plants can be very damaging, and are generally not visible to the naked eye. Their microscopic size means that associating them with crop damage is mainly dependent on determining the symptoms of their effects on plants or plant growth. The damage and symptoms caused can be visible above ground but, apart from poor growth and yield of the plants, the specific nematode can only be seen below the ground in the plant organs; mainly the roots, rhizomes, bulbs, corms and tubers.This book aims to help people working commercially with crop plants to identify and improve their diagnosis of nematodes of agricultural importance. There is an introductory chapter on nematode biology and parasitism, and the crops they are likely to attack. Crop chapters are divided into grain legumes, vegetables, flower crops, cereals, root and tuber crops, and tree and plantation crops. Coverage includes distribution, identification, symptoms and diagnosis, with management suggestions also presented. A final chapter outlines common methods used in nematology.This book is invaluable to a range of professionals including growers, farmers and students working in crop protection, plant pathology, and agriculture.
