Download or read book Edible Insects written by Heimo Mikkola and published by BoD – Books on Demand. This book was released on 2020-01-29 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insect protein production through ‘mini-livestock farming’ has enormous potential to reduce the level of malnutrition in critical areas across the world. It has been estimated that insect eating is practised regularly by over two billion people, mostly in China and in most tropical countries in Africa, South America, and Asia. However, eating insects has been taboo in many western nations. Reasons for this are discussed in this book with examples from Finland and the UK. The enormous boom of insect farming in Finland started in September 2017 when the business type was legalized. However, a large part of the population found the insect food too expensive and exotic. UK research outlines a multitude of promising strategies to overcome ‘western’ resistance to eating insects. This book also includes a chapter on the potential of insect farming to increase global food security. It shows that Africa is a hotspot of edible insect biodiversity and there more than 500 species consumed daily. We have several examples of viable insect farming businesses that can fight poverty and malnutrition in developing countries and provide profit and wealth to rural farmers. The chapters of the book cover countries such as Cameroon, Ecuador, Finland, Ghana, India, Mexico, the UK, and the US.

Download or read book Ecological Effects of Water level Fluctuations in Lakes written by Karl M. Wantzen and published by Springer Science & Business Media. This book was released on 2009-05-06 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most aquatic ecosystems have variable water levels. These water-level fluctuations (WLF) have multiple effects on the organisms above and below the waterline. Natural WLF patterns in lakes guarantee both productivity and biodiversity, while untimely floods and droughts may have negative effects. Human impacts on WLF have led to a stabilization of the water levels of many lakes by hydraulic regulation, untimely drawdown due to water use, or floods due to water release from hydropower plants in the catchments. This book provides a first review in this field. It presents selected papers on the ecological effects of WLF in lakes, resulting from a workshop at the University of Konstanz in winter 2005. Issues addressed here include the extent of WLF, and analyses of their effects on different groups of biota from microorganisms to vertebrates. Applied issues include recommendations for the hydrological management of regulated lakes to reduce negative impacts, and a conceptual framework is delivered by an extension of the floodpulse concept for lakes. Current impacts on water use, including increasing demands on drinking and irrigation water, hydropower etc., and climate change effects on WLF make this book an essential resource for aquatic ecologists, engineers, and decision-makers dealing with the management of lake ecosystems and their catchments.
Download or read book Marine Insects written by Lanna Cheng and published by North-Holland. This book was released on 1976 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first exhaustive review of literature on marine insects, which are defined in this volume as those that spend at least part of their life in association with the marine environment. Not only are true insects, such as the Collembola and insect parasites of marine birds and mammals, considered, but also other kinds of intertidal air-breathing arthropods, notably spiders, scorpions, mites, centipedes and millipedes, which live and feed with, or even on, the insects of marine habitats. The chapters, written by leading authorities, are divided into two sections, the first treating primarily ecological aspects, the second dealing with major groups of insects in marine environments.
Download or read book The Caddisfly Family Phryganeidae Trichoptera written by Glenn B. Wiggins and published by University of Toronto Press. This book was released on 1998-12-15 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of much of the scientific work in natural history museums is to explore and document the biological diversity of the planet. This book is an outstanding example of the museum tradition, offering the results of global research on the biosystematics of one of the families of case-making caddisflies, the Phryganeidae. Throughout his career as a museum curator, Glenn Wiggins has studied and written extensively on caddisflies of the aquatic insect order Trichoptera. Information acquired from field work and museum collections, and from the biological literature is synthesized into a taxonomic monograph. The Phryganeidae are the largest of all the caddisflies, but existing literature has led to problems in species identification, especially in Asia; nine species names were found to be synonyms of others, an unsually high proportion of 10 per cent of the described species. Fifteen genera comprising seventy-four species are recognized here, including three that are new to science. Generic keys are provided for adults, larvae, and pupae; keys to species are given for adults. Morphological structures used in the keys are fully illustrated in 246 line drawings and half-tone plates. Distribution maps are provided for most of the North American species. Hypotheses are inferred for the phylogeny of the genera, and for the species in each genus; the fossil history of the Phryganeidae is reviewed. From this base, the biogeography of the family is interpreted. Of evolutionary interest is an extraordinary relationship between larval case-making and pupation behaviour and the degradation of functional pupal mandibles. Contrasting colour patterns of the wings in some species of the Phryganeidae are interpreted for the first time in the Trichoptera as part of a protective warning system to deter predators. Variation in genitalic morphology far exceeding normal species limits is documented in two species, and the evolutionary implications are considered. Combined with fossil evidence that the Phryganeidae are the oldest of the case-making Trichoptera still extant, several of the atypical morphological and behavioural attributes discussed in this book can be interpreted as plesiomorphic, placing the Phryganeidae in a pivotal position for inferring phylogeny in the Trichoptera. A revised classification embodying much new information is proposed for the family Phryganeidae. The taxonomy, biology, and evolution of no other family of caddisflies has been treated as extensively.

Download or read book Insects and Pollution written by K. Heliovaara and published by CRC Press. This book was released on 2018-02-01 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects and Pollution provides a comprehensive overview of both the direct and indirect effects of pollution on insects and discusses the ecological and economic consequences of these changes. The book reviews studies on pollutant-induced changes in insects classified according to their trophic position, taxonomy, and developmental stage. These changes are considered on different spatial and temporal scales, in different climatic and vegetation zones, and in different habitats (with emphasis on coniferous forests). The book also describes the effects of a variety of pollutants on terrestrial and aquatic ecosystems. Other topics considered include the effects of pollutants on insect physiology, ecology and evolution, and updating and synthesizing data. Insects and Pollution is the first book to combine entomological and ecotoxicological perspectives to address the far-ranging effects of pollution on insects. It is essential reading for entomologists, ecotoxicologists, conservation biologists, and other professionals in the environmental sciences.
Download or read book The Biology and Ecology of Streams and Rivers written by Alan Hildrew and published by Oxford University Press. This book was released on 2023-06-19 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: The challenges that the world's running water systems now face have never been more numerous or acute; at the same time, these complex habitats remain absolutely crucial to human wellbeing and future survival. If rivers can ever be anything like sustainable, ecology needs to take its place as an equal among the physical sciences such as hydrology and geomorphology. A real understanding of the natural history and ecology of running waters must now be brought even more prominently into river management. The primary purpose of this textbook is to provide the up-to-date overview that students and practitioners will require to achieve this aim. The book's unifying focus is on rivers and streams as ecosystems in which the particular identity of organisms is not the main emphasis but rather the processes in which they are involved - specifically energy flow and the cycling of materials. It builds on the physicochemical foundations of the habitat templet and explores the diversity and adaptations of the biota, progressing from the population and community ecology of organisms and linking them to ecosystem processes and services in the wider biosphere via the complexities of species interactions and food webs. These include water quality and patterns of river discharge, as well as aesthetics, waste disposal, and environmental health. While the book is not primarily focused on application per se, each chapter addresses how humans affect rivers and, in turn, are affected by them. A final, future-oriented chapter identifies key strategic areas and sets a roadmap for integrating knowledge of natural history and ecology into policy and management. The Biology and Ecology of Streams and Rivers is an accessible text suitable for both senior undergraduate and graduate students taking courses in both lotic and general ecology as well as more established researchers, practitioners, managers, and conservationists requiring a concise and contemporary overview of running waters.
