Book Description
This book contains full descriptions of all the ring nematodes (484 species) reported from everywhere in the world that belong to the family Criconematidae, order Tylenchida. They are plant parasites living in het soil and so they have an economic importance. This book is amply illustrated with line drawings and SEM photographs that are based on microscopic and sub-microscopic observations. AUTHOR: Etienne Geraert was Zoology Professor at Ghent University, Belgium. From 1974 till 1998 he was also Associate Editor of the International Journal Nematologica (now Nematology) where he was responsible for the articles on morphology and taxonomy. He has already published a book on the morphology of the order Tylenchida and four books on the identification of plant-parasitic nematodes of the families Tylenchidae, Criconematidae, Dolichodoridae and Pratylenchidae. From 1990 till 2002 he was Director of the Master's Course in Nematology at Ghent University. 406 b/w images

Book Description
A unique treatise on the morphology and taxonomy of the order Mononchida. The mononchs represent a group of predatory nematodes that are natural enemies of other soil micro-organisms including plant-parasitic nematodes. The book includes detailed morphology of mononchs with emphasis on characters of taxonomic importance. Detailed diagnoses of the ordinal and familial groups and all the genera known to date are provided. A brief description of type species of each genus is followed by a complete list of all the valid species and their synonymies and an up-to-date key to species. The book is heavily illustrated with line drawings, microphotographs and SEM photographs of type or representative species. A complete bibliography until 2007 and an index are included.

Book Description
The present review study deals with few biological aspects of few fresh water fishes including catfishes based on published literature as worked out by various researchers of India. Many small fresh water fishes and catfishes have become threatened and endangered due to contamination, over exploitation, habitat destruction, water abstraction, siltation, habitat fragmentation, fish diseases and introduction of alien species. For sustainable utilization, proper planning related to conservation and management strategies are of utmost importance. The earlier studies on the various aspects of fish bionomics have been reviewed under the following headings Viz., length-weight relationship, relative condition factor, food and feeding habits, GSI,HIS, sex ratio and fecundity.

Book Description
Ecofriendly Pest Management for Food Security explores the broad range of opportunity and challenges afforded by Integrated Pest Management systems. The book focuses on the insect resistance that has developed as a result of pest control chemicals, and how new methods of environmentally complementary pest control can be used to suppress harmful organisms while protecting the soil, plants, and air around them. As the world’s population continues its rapid increase, this book addresses the production of cereals, vegetables, fruits, and other foods and their subsequent demand increase. Traditional means of food crop production face proven limitations and increasing research is turning to alternative means of crop growth and protection. Addresses environmentally focused pest control with specific attention to its role in food security and sustainability. Includes a range of pest management methods, from natural enemies to biomolecules. Written by experts with extensive real-world experience.

Book Description
Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.
