Download or read book Lake Kivu written by Jean-Pierre Descy and published by Springer Science & Business Media. This book was released on 2012-05-25 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the heart of Africa, a unique lake attracts the attention of scientists since the beginning of the 20th century. At the foot of the Virunga volcano chain, Lake Kivu harbors a vast amount of dissolved carbon dioxide and methane, making this lake the most dangerous lake on Earth. But the lake furnishes also many goods and services for surrounding populations and may soon become the most important energy supplier in the area. At the beginning of gas exploitation, the time has come for gathering the large amount of scientific information acquired during past and present research on Lake Kivu. The eleven chapters cover many aspects of the physics, geochemistry and biology of the lake, with a particular focus on the unique physical and geochemical features of the water column and on the ecological functioning of the surface waters. The impacts of the introduced fish species and the potential impacts of methane exploitation are also summarized. This multi-disciplinary book may also be used as an introduction to the limnology and biogeochemistry of large tropical lakes, as it covers various aspects of the physics, geochemistry, biology and ecology of the African Great Rift lakes.

Download or read book The Physiology of Insecta V5 written by Morris Rockstein and published by Elsevier. This book was released on 2012-12-02 with total page 669 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physiology of Insecta, Second Edition, Volume V, is part of a multivolume treatise that brings together the known facts, the controversial material, and the many unresolved and unsettled problems of insect physiology. It features chapters written by the outstanding workers in each of a wide range of insect function areas. It is designed to meet a manifest need, which has arisen from the phenomenal increase in research activity on insects, for an authoritative, comprehensive reference work in insect physiology. The book begins with a discussion of insect nutrition. This is followed by separate chapters on the physiology of digestion and absorption; the factors affecting insect heart rates; the electrical properties of the insect heart; and the hemocytes of insects. Subsequent chapters cover the physiological role and the adaptive significance of the main biochemical constituents of insect hemolymph; salt and water balance in insects; defense reactions in insects; and microsomal mixed-function oxidases.
Download or read book Africa and Mathematics written by Dirk Huylebrouck and published by Springer. This book was released on 2019-03-30 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume on ethnomathematics in Central Africa fills a gap in the current literature, focusing on a region rarely explored by other publications. It highlights the discovery of the Ishango rod, which was found to be the oldest mathematical tool in humanity's history, thereby shifting the origin of mathematics to the heart of Africa, and explores the different scientific hypotheses that emerged as a result. While it contains some high-level mathematics, the non-mathematical reader can easily skip these portions and enjoy the book’s survey of African history, culture, and art.
Download or read book Comparative Anatomy of the Gastrointestinal Tract in Eutheria II written by Peter Langer and published by Walter de Gruyter GmbH & Co KG. This book was released on 2017-10-23 with total page 804 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the series Handbook of Zoology deals with the anatomy of the gastrointestinal digestive tract – stomach, small intestine, caecum and colon – in all eutherian orders and suborders. It presents compilations of anatomical studies, as well as an extensive list of references, which makes widely dispersed literature accessible. Introductory sections to orders and suborders give notice to biology, taxonomy, biogeography and food of the respective taxon. It is a characteristic of this book that different sections of the post-oesophageal tract are discussed separately from each other. Informations on form and function of organs of digestion in eutherians are discussed under comparative-anatomical aspects. The variability and diversity of anatomical structures represents the basis of functional differentiations.
Download or read book The Gnu s World written by Richard D. Estes and published by University of California Press. This book was released on 2014-04-12 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first scholarly book on the antelope that dominates the savanna ecosystems of eastern and southern Africa. It presents a synthesis of research conducted over a span of fifty years, mainly on the wildebeest in the Ngorongoro and Serengeti ecosystems, where eighty percent of the world’s wildebeest population lives. Wildebeest and other grazing mammals drive the ecology and evolution of the savanna ecosystem. Richard D. Estes describes this process and also details the wildebeest’s life history, focusing on its social organization and unique reproductive system, which are adapted to the animal’s epic annual migrations. He also examines conservation issues that affect wildebeest, including range-wide population declines.
Download or read book African Ecology written by Clive Spinage and published by Springer Science & Business Media. This book was released on 2012-05-07 with total page 1582 pages. Available in PDF, EPUB and Kindle. Book excerpt: In view of the rapidly changing ecology of Africa ,this work provides benchmarks for some of the major, and more neglected, aspects, with an accent on historical data to enable habitats to be seen in relation to their previous state, forming a background reference work to understanding how the ecology of Africa has been shaped by its past. Reviewing historical data wherever possible it adopts an holistic view treating man as well as animals, with accent on diseases both human and animal which have been a potent force in shaping Africa’s ecology, a role neglected in ecological studies.
Download or read book The ecology and management of African wetland vegetation written by Patrick Denny and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in the biology of African 'wetlands' was initiated in the last century with the hypothesis that Lake Tanganyika was once part of a Jurassic sea, and was furthered by Cunnington's expedition at the beginning of this century which proved that it was not. In the late 1920's, ecological studies, encouraged by the growing importance of inland fisheries, were started hy British, French and Belgian biologists. Some twenty years later several government limnological research centres and fishery departments were established in tropical Africa, and scientific progress was accelerated. Scientific collaboration between the regions south of the Sahara was started formally in 1951 by the Scientific Council for Africa and stimulated by the International Biological Programme (1964-74) with its emphasis on biological productivity. Some of its interests were takcn on by SCOPE which recently selected continental wetlands as a Special Project; hence this book. The five authors, with-Patrick Denny as editor, have made a very valuable contribution both to science and to thc management of Africa's natural rcsourccs: thcy have filled a gap in the synthesis of knowledge about Africa's environments which is long overdue. The term 'wetland' is used today in several different contexts. For this purpose, it excludes the seas and large open inland waters. which are too deep for rooted plants, but includes the huge areas of floodplains and dambos which may change seasonally from standing water to very dry lands.
Download or read book Arthropoda Part B written by Marcel Florkin and published by Elsevier. This book was released on 2014-07-23 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical Zoology, Volume VI, Arthropoda Part B, provides zoologists and chemists with an overview of the state of knowledge in chemistry and zoology and an introduction to the existing literature. The treatise is arranged by phyla, an arrangement which seemed most suitable for presenting chemical information of zoological significance and for bringing to the attention of chemists those aspects of biochemical diversity of greatest potential interest. Each section, dealing with a major phylum, is introduced by a discussion of the biology and systematics of the group. This is followed by chapters dealing with various aspects of the biochemistry of the group. This volume contains 11 chapters that discuss the integument, hemolymph, blood respiratory pigments, hemolymph coagulation excretion, pigments, chemistry, toxicology, and pharmacology of Arthropoda. The respiration, energy metabolism, and chemical ecology of Crustacea as well as the oxidative metabolism of Insecta are also covered.

Download or read book Biotic Diversity in Agroecosystems written by D. Pimentel and published by Elsevier. This book was released on 2012-12-02 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: The preservation of biodiversity is a high priority among biologists, ecologists and environmentalists. The impact that human activities have on biodiversity is clear; however, few studies have focused on the importance of biodiversity to natural and agricultural ecosystems. In fact, many natural species are essential to sustainable agricultural programs. A new school of thought is appreciating the ecological principles and benefits that diversity of natural biota have for humans and the environment. Landscape ecology and agroecology can play a major role in protecting the environment and conserving biological diversity. The practical opportunities for improving the sustainability of agriculture and making it more environmentally sound were discussed at the Symposium on Agroecology and Conservation Issues, from which 22 papers were collected for this volume. Strategies for increasing biodiversity in agricultural landscapes are provided alongside discussion that agriculture will continue to spread into forests, to meet the growing need for food. Although humans recognize the value of crop and livestock species, few really appreciate the fact that agriculture and forestry cannot function in a productive sustainable way when significant numbers of species in natural biota are lost.
