Available in PDF, EPUB and Kindle. Book excerpt: The virtual impossibility of extracting the many different species from a habitat with equal efficiency by a single method (e.g. Nef, 1960). 1.1 Population estimates Population estimates can be classified into a number of different types; the most convenient classification is that adopted by Morris (1955), although he used the terms somewhat differently in a later paper (1960). 1.1.1 Absolute and related estimates The animal numbers may be expressed as a density per unit area of the ground of the habitat. Such estimates are given by nearest neighbour and related techniques (Chapter 2), marking and recapture (Chapter 3), by sampling a known fraction of the habitat (Chapter 4-6) and by removal sampling and random walk techniques (Chapter 7). Absolute population The number of animals per unit area (e.g. hectare, acre). It is almost impossible to construct a budget or to study mortality factors without the conversion of population estimates to absolute figures, for not only do insects often move from the plant to the soil at different developmental stages, but the amount of plant material is itself always changing. The importance of obtaining absolute estimates cannot be overemphasized.

Download or read book Southwood s Ecological Methods written by Peter A. Henderson and published by Oxford University Press. This book was released on 2021-04-01 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Methods by the late T.R. E. Southwood and revised over the years by P. A. Henderson has developed into a classic reference work for the field biologist. It provides a handbook of ecological methods and analytical techniques pertinent to the study of animals, with an emphasis on non-microscopic animals in both terrestrial and aquatic environments. It remains unique in the breadth of the methods presented and in the depth of the literature cited, stretching right back to the earliest days of ecological research. The universal availability of R as an open source package has radically changed the way ecologists analyse their data. In response, Southwood's classic text has been thoroughly revised to be more relevant and useful to a new generation of ecologists, making the vast resource of R packages more readily available to the wider ecological community. By focusing on the use of R for data analysis, supported by worked examples, the book is now more accessible than previous editions to students requiring support and ideas for their projects. Southwood's Ecological Methods provides a crucial resource for both graduate students and research scientists in applied ecology, wildlife ecology, fisheries, agriculture, conservation biology, and habitat ecology. It will also be useful to the many professional ecologists, wildlife biologists, conservation biologists and practitioners requiring an authoritative overview of ecological methodology.

Download or read book Foundations of Bioenergetics written by Harold Morowitz and published by Elsevier. This book was released on 2012-12-02 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foundations of Bioenergetics provides an introduction to the physical foundations of bioenergetics and the methods of applying these constructs to biological problems. It combines parts of thermal physics, biochemistry, ecology, and cellular and organismic biology into a single coherent work. Much of the material in this volume comes from ""Entropy for Biologists,"" an introductory thermodynamics book aimed particularly at life scientists. Some of the topics originally appeared in the monograph ""Energy Flow in Biology."" The current volume expands on that material with respect to biological applications and attempts to bridge the gap between physics and biology. The book explains basic concepts such as energy, temperature, the second law of thermodynamics, entropy, information theory, and statistical mechanics. It discusses the relations between thermodynamics and statistical mechanics, free-energy functions, radiant energy, the free energy of cells and tissue, chemical kinetics, and cyclic flows. It examines the relationships between energy flows and biological processes; applications of the concepts of Gibbs free energy, chemical potential, and activity; and measurements of temperature, energy, and thermochemical quantities. The book also includes chapters that deal with irreversible dynamics, irreversible theory, and osmotic flow.
Download or read book Bioenergetic Processes of Cyanobacteria written by Guenter A. Peschek and published by Springer Science & Business Media. This book was released on 2011-06-08 with total page 733 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is unique among a number of books on cyanobacteria because it focuses on the bioenergetics of these widespread organisms which are the evolutionary prerequisite for the development of all higher forms of life on our "blue" planet. The book primarily addresses questions of energy conversion by the fundamental bioenergetic processes: (oxygenic) photosynthesis, (aerobic) respiration, and (anaerobic) fermentation which uniquely occur together in these prokaryotic cells. Thermophilic cyanobacteria offer the most suitable material for high resolution structure analyses of Photosystem I and II and other electron transport complexes by X-ray crystallography (for example, at present the structure of Photosystem II at atomic resolution is only known for these organisms). These achievements during the last decade represent a milestone in our understanding of the complexes which are crucial for solar energy exploitation through photosynthetic water splitting. The present work represents an ambitious attempt to achieve the goal of a synoptic state-of-the-art picture by casting together the mosaics of detailed knowledge described by leading experts in the field. It contains 24 chapters written by 35 authors from Europe, USA, India and Japan. The book is aimed at reaching a broad audience ranging from students to experienced scientists. The editors wish all readers a pleasant and stimulating journey through the fascinating “world” of the bioenergetics of cyanobacteria and sincerely hope that this book will not only be of great value for the experts but also entice young people into this exciting research area with the aim to address successfully the challenging problems of high relevance that are still waiting for a satisfactory answer.

Download or read book Fish Ecophysiology written by J.C. Rankin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes. a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes. ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts. in the deep sea. in the cold antarctic. and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specialisations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins. sailfish and warm-blooded tunas, air-breathing in catfish and lungfish. parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious. delicious and diverse food. Rational exploi management of our global stocks of fishes must rely upon a detailed tation and and precise insight of their biology. The Chapman [.,. Hall Fish and Fisheries series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology. zoology. ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of IIsh and t1sheries.

Download or read book Principles of Bioenergetics written by Vladimir P. Skulachev and published by Springer Science & Business Media. This book was released on 2012-12-15 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles of Bioenergetics summarizes one of the quickly growing branches of modern biochemistry. Bioenergetics concerns energy transductions occurring in living systems and this book pays special attention to molecular mechanisms of these processes. The main subject of the book is the "energy coupling membrane" which refers to inner membranes of intracellular organelles, for example, mitochondria and chloroplasts. Cellular cytoplasmic membranes where respiratory and photosynthetic energy transducers, as well as ion-transporting ATP-synthases (ATPases) are also part of this membrane. Significant attention is paid to the alternative function of mitochondria as generators of reactive oxygen species (ROS) that mediate programmed death of cells (apoptosis and necrosis) and organisms (phenoptosis). The latter process is considered as a key mechanism of aging which may be suppressed by mitochondria-targeted antioxidants.
Download or read book Biology and Ecology of Fishes written by James S. Diana and published by John Wiley & Sons. This book was released on 2023-06-08 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology and Ecology of Fishes Immerse yourself in the world of fish ecology with the newest edition of this essential introduction The study of fish ecology has traditionally proceeded along two tracks: the first is more basic, concerned with the anatomy, physiology and theoretical ecology of fish, and the second is more practical, concerning itself with fish populations, management, and habitats. Many fish researchers have come to view this distinction as artificial, and to develop a new study of fish that combines both tracks in a single holistic approach. It has never been more critical for introductory textbooks to represent this combined study in order to prepare the next generation of fish biologists and fishery scientists. Biology and Ecology of Fishes meets this need with a textbook that incorporates both biology and population management. Beginning with a general introduction to aquatic life and ecosystems, this book covers anatomical, environmental, and ethological topics to give a thoroughly rounded view of its subject, promising to serve as the fundamental introduction to multidisciplinary fish studies. Readers of the third edition of Biology and Ecology of Fishes will also find: Detailed coverage of subjects including growth and bioenergetics, feeding and predation, mortality and recruitment and more Increased attention to stressors of fish populations and communities New and revised chapters that introduce quantitative methods and present emerging issues facing fish populations and communities Biology and Ecology of Fishes is a useful overview for advanced undergraduate and graduate students studying fish ecology or fishery biology, as well as a reference for researchers and professionals in fish ecology, fish population management, and related fields.
