Available in PDF, EPUB and Kindle. Book excerpt: Droughts are a major hazard to both natural and human-dominated environments and those, especially of long duration and high intensity, can be highly damaging and leave long-lasting effects. This book describes the climatic conditions that give rise to droughts, and their various forms and chief attributes. Past droughts are described including those that had severe impacts on human societies. As a disturbance, droughts can be thought of as “ramps” in that they usually build slowly and take time to become evident. As precipitation is reduced, flows from catchments into aquatic systems decline. As water declines in water bodies, ecological processes are changed and the biota can be drastically reduced, though species and populations may survive by using refuges. Recovery from drought varies in both rates and in degrees of completeness and may be a function of both refuge availability and connectivity. For the first time, this book reviews the available rather scattered literature on the impacts of drought on the flora, fauna and ecological processes of aquatic ecosystems ranging from small ponds to lakes and from streams to estuaries. The effects of drought on the biota of standing waters and flowing waters and of temporary waters and perennial systems are described and compared. In addition, the ways in which human activity can exacerbate droughts are outlined. In many parts of the world especially in the mid latitudes, global warming may result in increases in the duration and intensity of droughts. Drought and Aquatic Ecosystems is essential reading for freshwater ecologists, water resource managers and advanced students.

Download or read book Diseases of Horticultural Crops: Nematode Problems and their Management written by P. Parvatha Reddy and published by Scientific Publishers. This book was released on 2008-07-01 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nematodes continue to threaten horticultural crops throughout the world, particularly in tropical and sub-tropical regions. Estimated overall average annual yield loss of the world's major horticultural crops due to damage by plant parasitic nematodes is 13.54%. Monetary losses due to nematodes on 10 horticultural crops, six of which are life sustaining were estimated at US$ 19.37 billion annually based on 1984 production figures and prices. These deleterious effects on plant growth result in reduced yields and poor quality of horticultural crops. Nematode management is therefore, important for high yields and quality that are required by the high cost of modern crop production. The information on nematode diseases and their management, especially crop wise, is very much scattered and there is no book which deals entirely with the above aspects on horticultural crops. This book deals with nematode diseases and their management in horticultural crops such as fruit, vegetable, orname-ntal, medicinal, aromatic, plantation, spice and tuber crops. Each nematode disease is described in adequate detail under the following heads: economic importance, crop losses, distribution, symptoms, hosts range, life cycle, races/ biotypes, host-parasite relationship, histopathology, ecology, spread, survival, interaction with other pathogens and management. The management methods presented includes regulatory, physical cultural, chemical, biological, host resistance and integrated approach. An entire chapter is devoted for sources of availability of critical inputs used for nematode management which would be very useful to the farmers. Very useful information on certain aspects of nematode management is presented in Appendix. The book is adequately illustrated with about 50 figures. This book is a practical guide to practicing farmers of horticultural crops. Further, it is a useful reference to policy makers, research and extension workers and students. The material can also be used for teaching under-graduate and post-graduate courses.

Available in PDF, EPUB and Kindle. Book excerpt: Plant parasitic nematodes are one of the least understood agricultural pest problems throughout the world. Science of Plant Nematology has grown rapidly is the last three decades. There is a wide gap between the vast information generated for nematode control and that, which is actually utilised. The present book ``Advances in Nematology'' provides an authoritative review account of many aspects of current interest and progress in the field of Plant Nematology that has been made in the recent past. This book includes 21 articles by eminent nematologist on different aspects of the subject. Information on application of molecular biology in nematology, nematodes as biological model, race status in plant parasitic nematodes and nematode vectors of plant diseases have been reviewed covering all major aspects. Nematode diseases on wheat, rice, tobacco, mint, barley and horticultural crops and their management, specially in context to Indian scenario have been covered. Newer approaches for the management of plant parasitic nematodes including use of VAM fungi, biocontrol agents and integrated nematode management strategies have been included to project out their use on field scale. Articles on role of nematodes in disease complexes with fungi, genetic studies on the resistance of barley, breeding for nematode resistance in forage legumes and nematode pests of economically important crops in India and their managements have been added to the value of the book. Scholars and students of Nematology, researchers and extension workers and plant pathologist will find this book very useful.

Available in PDF, EPUB and Kindle. Book excerpt: Nematodes represent a unique challenge to agricultural research, in that they combine the potential for serious reductions in growth and yield in a wide range of crop plants, often with rather nonspecific and easily misdiagnosed symptoms. Development of the concept of pest management and their implementation have led to a greater appreciation of the need for a wide range of tactics for nematode control. The present book ``Nematode Management in Plants'' provides an authoritative review of many aspects of nematode control and progress in the field of nematode management programme. The volume contains eighteen articles covering application of cropping sequences, plant products and botanicals, latex, bioagents and biological control practices for the management of nematode pests. Topics covering use of Azotobacter, Bacillus thuringiensis and VAM Fungi for reducing nematode pests have been specially included to project their role in the present century. Information on Integrated Nematode Management have been included with special emphasis on biocontrol management practices. This book will be useful to Plant Pathologist, Nematologist, research and extension workers, teachers and students.

This book was released on 2019-04-23 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant embryology, dealing with the regularities of initiation and the first stages of development of an organism, is now flourishing because of the overall progress being made in natural sciences. Such discoveries of the 20th century as production of plants from a single somatic cell, experimental haploidy, and parasexual hybridization were of general biological significance. The combined efforts of embryologists, geneticists and molecular biologists yielded the discovery of specific genes that control meiosis, egg cell development and early stages of embryogenesis. The tendency to synthesize data of embryology and genetics has become increasingly noticeable. It is connected with the fact that the majority of problems connected with morphogenesis, such as differentiation, specialization, the evaluation of features and the definition of the notionsgene and feature andgenotype and phenotype concern embryology and genetics (embryogenetics) in one way or another. Evolutionary embryology has given rise to a new approach to the study of problems of adaptation in plants. In connection with the problem of preserving biological diversity under conditions of ecological stress, special attention is paid to ecological embryology, revealing the critical periods in early ontogenesis and plasticity and tolerance of reproductive systems at the level of species and population. The study of variability of morphogenesis and phenotype in population (life cycle variations and the diversity of reproductive systems) is the most important point in the population embryology of plants.
