Research on the genetic regulation of insect physiology and behaviour is a fairly new field in biological research. The development of modern techniques like transcriptome studies, micro-arrays and RNA interference has altered the way we study insects. In this book, several candidate genes regulating different aspects of insect physiology and behaviour are studied in three different insect models, with a great focus on the desert locust. It was found that the genes studied in this work could, in the future, be important in solving the locust pests that threaten a large part of the worlds population. We have found that the foraging gene is implicated in the early changes during the gregarisation process of this locust and that the circadian clock genes period and timeless as well as the transcriptional factor fruitless can influence locust reproduction. These results can lead to new ways of locust pest management.
A growth depressing effect of high dietary neutral lipid levels in cultured marine fish larvae has been reported. This may be the result of a decrease in the efficiency or activity of digestive enzymes, a reduction in absorption efficiency and/or a decrease in food intake. This book presents work that was carried out on commercially valuable species (Atlantic herring, Senegalese sole, European seabass and gilthead seabream), to investigate the effects of neutral lipid level and source (fatty acid composition) on some of these key factors. The results collectively indicate that lipid transport across the enterocytes may be more problematic when feeding high neutral lipid diets than lipid digestion, although both factors are likely to intervene. Results also suggest that food intake might be affected by the lipid source included in the diet. Therefore, the neutral lipid level in diets for marine fish larvae has a significant impact in several factors influencing growth but clearly it cannot be dissociated of its fatty acid composition, which appears to play a central role on the nutritional and physiological effects of dietary lipid, at the ingestion, digestion and absorption levels.
This book forms a valuable platform for the upcoming fisheries businessmen, same time it will definitely encourage the further research in the area as well. Communication of information to un-organised fish sellers will motivate them to initiate modifications in their business. In India, In recent years slow transformation of unorganized fish retail marketing into an organized has began to be noticed, through entry of private retailer giants. This has shown the significance for working on consumer behaviour and making it available to professionals and common man. The Book Highlights Consumers behaviour at organised fish retail outlet; with reference to its preferences towards form of fish, taste and buying preferences. It put light on consumer attitudes and buyers behaviour In the Marketplace. This book will benefit all Marketing Students, Executives and Managers Especially the new entrants in the marketing.
Yield of water stressed sugarcane is about 50% of the yield of well watered sugarcane though it is one of the grassy crops that well adapted to the dry environmental conditions. Also, sugarcane shows greater genotypic variation in performance within a water regime as well. Hence, investigation of physiological response which could ultimately determine the yield of the crop under different growing conditions is important to achieve the maximum yield by minimizing the yield gap between actually obtained and genetically determined maximum yields in improved genotypes. However, studying these aspects of sugarcane in plant and ratoon crops under different natural environmental conditions is tedious and time consuming process. Despite the circumstances, this book provides the research background and the findings of the field experiment conducted in seven years period to investigate the effects of soil moisture on growth, physiology, yield and ratoonability of sugarcane under irrigated and rainfed conditions in sub-tropical climatic conditions that could be very useful guidelines for the researchers and university students who engaged in crop physiological studies.

It is indeed a great pleasure to take this opportunity to express a deep sense of gratitude to my Research Guide Dr.K.B.Shejule, Dept.of Zoology,Dr.B.A.M.U.Aurangabad.The toxic chemicals are heavily used to increase the crop yield required for feeding the ever increasing the human population.These pesticides through surface runoff reaches to the unrestricted areas like ponds & rivers which alters the physico-chemical properties of water & is toxic to aquatic organism and cause deleterious effect or even death to the aquatic animals. The wide spread use of pesticides not only brought adverse influence on agro – ecosystems but also caused alteration in physiological processes of non-target organisms. This book guides you to for toxicity evaluation of pesticides to fresh water fish.It will help you to study the respiratory physiology,to study histopathological changes in the liver and kidney after exposure to the sublethal concentration of Organophosphate pesticides?.This book is useful to research students of pesticide toxicology.It is also helpful to environmental biologist.
Fish are excellent swimmers with high swimming efficiency and perfect manoeuvring abilities. Designing a robotic fish with fish-like swimming behaviour in a dynamic environment is such a challenging task, that it requires a full understanding of hydrodynamics, fish propulsion mechanisms, and the approaches for mimicking the real fish swimming. This book is based on author's PhD thesis finished at University of Essex in 2007, which aims to develop: (i) a control architecture for autonomous control, (ii) basic fish-like swimming ability, (iii) behaviour-based intelligent control, and (iv) online learning algorithms. The Essex robotic fish has been reported widely by major media including BBC, ABC, CNN and National Geographic since 2005. Many multimedia resources can be found in the Internet.

This book argues that gender and race are physiologically constituted through the biopsychosocial effects of sexism and racism. Sullivan skillfully combines feminist and critical philosophy of race with the biological and health sciences to provide new strategies for fighting male and white privilege.

Bottom soil plays an important role in determining the productivity of fish ponds by providing sustenance to fish food organisms and, thereby, the growth of fishes. The behaviour and response of different nutrient inputs, used for improving the productivity of such culture system, are also influenced largely by the nature and properties of the pond soils. The book provides some basic information about the methods of assessing and also maintaining threshold levels of different plant nutrients in fish ponds through soil system based approach for increasing their productivity.
