Biology of Earthworms (Paperback, 2011 ed.): Ayten Karaca Biology of Earthworms (Paperback, 2011 ed.)
Ayten Karaca
R4,497 Discovery Miles 44 970 Ships in 10 - 15 working days

Earthworms, which belong to the order Oligochaeta, comprise roughly 3,000 species grouped into five families. Earthworms have been called 'ecosystem engineers'; much like human engineers, they change the structure of their environments. Earthworms are very versatile and are found in nearly all terrestrial ecosystems. They play an important role in forest and agricultural ecosystems. This Soil Biology volume describes the various facets of earthworms, such as their role in soil improvement, soil structure, and the biocontrol of soil-borne plant fungal diseases. Reviews discuss earthworms' innate immune system, molecular markers to address various issues of earthworm ecology, earthworm population dynamics, and the influences of organic farming systems and tillage. Further topics include the characteristics of vermicompost, relationships between soil earthworms and enzymes, the role of spermathecae, copulatory behavior, and adjustment of the donated sperm volume.

This section of the Handbook of Zoology is intended as a comprehensive and exhaustive account of the biology of the taxa Gastrotricha, Nematoda, Nematomorpha, Priapulida, Kinorhyncha, Loricifera, Gnathostomulida, Micrognathozoa, Rotifera, Seisonida and Acanthocephala, covering all relevant topics such as morphology, ecology, phylogeny and diversity. The series is intended to be a detailed and up-to-date account of these taxa. As was the case with the first edition, the Handbook is intended to serve as a reliable resource for decades. Many of the taxa of this volume are comparatively unknown to many biologists, despite their diversity and importance for example in meiofaunal communities (Gastrotricha, Rotifera, Gnathostomulida), their fascinating recent discoveries (Loricifera and Micrognathozoa), their importance as parasites (many nematodes, Nematomorpha, Acanthocephala) and their importance for evolutionary questions (e.g. Priapulida, Gastrotricha). The groups covered range from those poor in species (such as Micrognathozoa with 2 known species) to the species-rich and diverse Nematoda and their ca. 20.000 described species. While each taxon is covered by one chapter, nematodes are treated in several chapters dedicated to their structural, taxonomic and ecological diversity.

Handbook of Genetics - Volume 5: Molecular Genetics (Paperback, Softcover reprint of the original 1st ed. 1976): Robert King Handbook of Genetics - Volume 5: Molecular Genetics (Paperback, Softcover reprint of the original 1st ed. 1976)
Robert King
R3,133 Discovery Miles 31 330 Ships in 10 - 15 working days

Many modern geneticists attempt to elucidate the molecular basis of phenotype by utilizing a battery of techniques derived from physical chemistry on subcellular components isolated from various species of organisms. Volume 5 of the Handbook of Genetics provides explanations of the advantages and shortcomings of some of these revolutionary tech niques, and the nonspecialist is alerted to key research papers, reviews, and reference works. Much of the text deals with the structure and func tioning of the molecules bearing genetic information which reside in the nucleus and with the processing of this information by the ribosomes resid ing in the cytoplasm of eukaryotic cells. The mitochondria, which also live in the cytoplasm of the cells of all eukaryotes, now appear to be separate little creatures. These, as Lynn Margulis pointed out in Volume 1, are the colonial posterity of migrant prokaryotes, probably primitive bacteria that swam into the ancestral precursors of all eukaryotic cells and remained as symbionts. They have maintained themselves and their ways ever since, replicating their own DNA and transcribing an RNA quite different from that of their hosts. In a similar manner, the chloroplasts in all plants are self-replicating organelles presumably derived from the blue-green algae, with their own nucleic acids and ribosomes. Four chapters are devoted to the nucleic acids and the ribosomal components of both classes of these semi-independent lodgers. Finally, data from various sources on genetic variants of enzymes are tabulated for ready reference, and an evaluation of this information is attempted."

Insects and Sustainability of Ecosystem Services (Hardcover, New): Timothy D. Schowalter Insects and Sustainability of Ecosystem Services (Hardcover, New)
Timothy D. Schowalter
R4,168 Discovery Miles 41 680 Ships in 12 - 17 working days

With few exceptions, insects are perceived in industrialized countries as undesirable pests. In reality, relatively few insects interfere with us or our resources. Most have benign or positive effects on ecosystem services, and many represent useful resources in non-industrialized countries. Challenging traditional perceptions of the value of insects, Insects and Sustainability of Ecosystem Services explores the ways insects affect the ecosystem services we depend upon. It also fosters an appreciation for the amazing diversity, adaptive ability, and natural roles of insects. The book discusses how the ways in which we manage insects will determine an ecosystem's capacity to continue to supply services. It reviews aspects of insect physiology, behavior, and ecology that affect their interactions with other ecosystem components and ecosystem services, emphasizing critical effects of insects on the sustainability of ecosystem processes and services. The author examines the integration of insect ecology with self-regulatory aspects of ecosystems that control primary production, energy and nutrient fluxes, and global climate-functions that underlie the sustainability of ecosystem services. Clearly, we need environmental policies that meet needs for pest control where warranted, but do not undermine the important contributions of insects to sustaining ecosystem processes and services. With in-depth coverage of the multiple, often compensatory, effects of insects on various resources or ecosystem services and on the consequences of control tactics for those resources or services, Insects and Sustainability of Ecosystem Services recommends changes in perspectives and policies regarding insects that will contribute to sustainability of ecosystem services.

J.Robin Harris
R5,922 Discovery Miles 59 220 Ships in 10 - 15 working days

This volume of the Subcellular Biochemistry series is the result of the long-standing research interest of the editor in the molecular mechanism underlying Alzheimer's disease and other amyloid diseases, indicated also by the earlier book in the series (Volume 38), devoted to Alzheimer's disease. The broad coverage within the present amyloidogenesis book represents an attempt to collate current knowledge relating to the proteins and peptides involved in most of the known amyloid diseases, together with some amyloid/fibril-forming proteins and peptides that are not involved in diseases. Thus, the range of topics included is comprehensive and furthermore it was thought appropriate to include both basic science and clinical presentation of the subjects under discussion.

S. Osawa, Z.-H Su, Y. Imura
R2,972 Discovery Miles 29 720 Ships in 10 - 15 working days

Carabid ground beetles, sometimes called "walking jewels," are among the most thoroughly investigated insects in the world. This book presents the results of molecular phylogenetic analyses of 2000 specimens, including 350 species and that cover more than 90% of the known genera, from 500 localities in 35 countries. These comprehensive analyses using mitochondrial DNA-based dating suggest that carabid diversification took place about 40 to 50 million years ago as an explosive radiation of the major genera, coinciding with the collision of the Indian subcontinent and Eurasian land mass. The analyses also lead to surprising conclusions suggesting discontinuous evolution and parallel morphological evolution. With numerous color illustrations, this book presents readers with the dynamic principles of evolution and the magnificent geographic history of the earth as revealed by the study of beetles.

Arthropod Relationships (Paperback, Softcover reprint of the original 1st ed. 1998): Richard A. Fortey, Richard H. Thomas Arthropod Relationships (Paperback, Softcover reprint of the original 1st ed. 1998)
Richard A. Fortey, Richard H. Thomas
R5,870 Discovery Miles 58 700 Ships in 10 - 15 working days

The arthropods contain more species than any other animal group, but the evolutionary pathways which led to their current diversity are still an issue of controversy. Arthropod Relationships provides an overview of our current understanding, responding to the new data arising from sequencing DNA, the discovery of new Cambrian fossils as direct evidence of early arthropod history, and developmental genetics. These new areas of research have stimulated a reconsideration of classical morphology and embryology. Arthropod Relationships is the first synthesis of the current debate to emerge: not since the volume edited by Gupta was published in 1979 has the arthropod phylogeny debate been, considered in this depth and breadth. Leaders in the various branches of arthropod biology have contributed to this volume. Chapters focus progressively from the general issues to the specific problems involving particular groups, and thence to a consideration of embryology and genetics. This wide range of disciplines is drawn on to approach an understanding of arthropod relationships, and to provide the most timely account of arthropod phylogeny. This book should be read by evolutionary biologists, palaeontologists, developmental geneticists and invertebrate zoologists. It will have a special interest for post-graduate students working in these fields.

Bina Pani Das
R2,021 Discovery Miles 20 210 Ships in 10 - 15 working days

Japanese Encephalitis (JE), a mosquito borne disease, is the leading cause of viral encephalitis in 14 Asian countries due to its epidemic potential, high case fatality rate and increased possibility of lifelong disability in patients who recover from this dreadful disease. In spite of seriousness of the disease, still only few books are available for ready reference. Hence, this book will be useful for students, entomologists, paramedical staff and vector control managers in public health. The objective of the book is to disseminate the knowledge gained by the author from ecological studies on JE vectors undertaken in 2 endemic and 2 non endemic areas of Northern India over a period of last 15 years (1998-2012) of research in the field of ecology of mosquito vectors of JE virus initially at National Institute of Communicable Diseases (Ministry of Health & Family Welfare, Government of India), Delhi and later at Jamia Millia Islamia, a Central University, Delhi, to anyone who wishes to curtail death of children due to this dreaded disease. Of the thousand suspected JE deaths in India annually, more than 75% is contributed by Northern India wherein disease transmission failed to be explained based on entomological evidence due to inadequate mosquito surveillance tool used in determining JE vector density. In order to overcome the above problem, Dr Bina Pani Das, the author of this book, developed "BPD hop cage method", a simple, cost effective, and operationally feasible surveillance tool specially designed to capture predominantly day resting adult Cx. tritaeniorhynchus mosquitoes, the principal JE vector species in the country from land and aquatic vegetation.

R5,820 Discovery Miles 58 200 Ships in 10 - 15 working days

Egg Parasitoids in Agroecosystems with emphasis on Trichogramma was conceived to help in the promotion of biological control through egg parasitoids by providing both basic and applied information. The book has a series of chapters dedicated to the understanding of egg parasitoid taxonomy, development, nutrition and reproduction, host recognition and utilization, and their distribution and host associations. There are also several chapters focusing on the mass production and commercialization of egg parasitoids for biological control, addressing important issues such as parasitoid quality control, the risk assessment of egg parasitoids to non-target species, the use of egg parasitoids in integrated pest management programs and the impact of GMO on these natural enemies. Chapters provide an in depth analysis of the literature available, are richly illustrated, and propose future trends.

R4,794 Discovery Miles 47 940 Ships in 10 - 15 working days

Following the original initiative of the International Organisation for Biological Control some 15 years ago, research groups and agrochemical companies have been investigating the effects of pesticides on beneficial organisms, devising laboratory and field test methods and lately developing protocols for regulatory testing requirements in Europe. This work, and the application of agreed protocols for testing, is of crucial importance to the environmentally acceptable use of pesticides and to the further development of Integrated Pest Management systems, and the objective of this book is to review the origins and progress of the research - what has been accomplished, what is the current position and what still needs to be done.

Konrad Wiese
R6,528 Discovery Miles 65 280 Ships in 10 - 15 working days

This book represents Part 2 of a venture started by distinguished neuroscientists to visualize and advertise the experimentally advantageous preparations of the crustacean nervous system. The advantage is a combination of ease of dissection of key structures and the possibility of repeatedly accessing identified individual cells to measure the detailed response of the system to the experimentally imposed stimulus program. Of course, the neurosciences have to focus their research on the nervous system of mammals and man in order to understand the principles of function and their regulation if malfunctions occur. This is in line with efforts to investigate nervous systems throughout the animal kingdom. The specific potential of the encountered systems for exploratory research into hitherto unexplained functions of the brain may very well be a key to new insights. The simply organized nervous system of crustaceans performs tasks of vital importance imposed on the organism. Hence this system consists of a complete set of neural circuitry open for inspection and measurement by systematic investigation. The first volume, The Crustacean Nervous System, contains exhaustive reports on experimental work from all sectors of neuroscience using crayfish and lobsters. This second volume, Crustacean Experimental Systems in Neurobiology," contains excellent reviews on significant topics in neurobiology. Each section is introduced by short texts written by the section editors of the Crustacean Nervous System. More, prominent authors explain their approach to understanding the brain using a selection of experiments involving visual orientation, neuromuscular systems and identification of principles of neural processing.

R5,796 Discovery Miles 57 960 Ships in 10 - 15 working days

Insect Learning is a comprehensive review of a new field. Until recently, insects were viewed as rigidly programmed automatons; now, however, it is recognized that they can learn and that their behavior is plastic. This fundamental change in viewpoint is causing a re-examination of all aspects of the relationship between insects and their environment. This change in perspective is occurring at a time of heightened interest in brain function in both vertebrates and invertebrates. Insects potentially play a major role in this expanding area. Because of their experimental tractability and genetic diversity, they provide unique opportunities for testing hypotheses on the ecology and evolution of learning. As organisms of economic importance, they are perennial objects of research by both basic and applied scientists. Insect Learning covers both social and non-social insects from multiple perspectives. The book covers mechanisms; syntheses of work on physiology, behavior, and ecology; and micro- and macroevolution. The concluding section discusses future directions for research, including applications to pest management.

R3,018 Discovery Miles 30 180 Ships in 10 - 15 working days

Claire Detrain, Jean-Louis Deneubourg and Jacques Pasteels Studies on insects have been pioneering in major fields of modern biology. In the 1970 s, research on pheromonal communication in insects gave birth to the dis cipline of chemical ecology and provided a scientific frame to extend this approach to other animal groups. In the 1980 s, the theory of kin selection, which was initially formulated by Hamilton to explain the rise of eusociality in insects, exploded into a field of research on its own and found applications in the under standing of community structures including vertebrate ones. In the same manner, recent studies, which decipher the collective behaviour of insect societies, might be now setting the stage for the elucidation of information processing in animals. Classically, problem solving is assumed to rely on the knowledge of a central unit which must take decisions and collect all pertinent information. However, an alternative method is extensively used in nature: problems can be collectively solved through the behaviour of individuals, which interact with each other and with the environment. The management of information, which is a major issue of animal behaviour, is interesting to study in a social life context, as it raises addi tional questions about conflict-cooperation trade-oft's. Insect societies have proven particularly open to experimental analysis: one can easily assemble or disassemble them and place them in controllable situations in the laboratory."

R4,512 Discovery Miles 45 120 Ships in 10 - 15 working days

This book was conceived to mark the Silver Jubilee of the British Butterfly Conservation Society. Interest in the conservation of butterflies has increased so rapidly that it is difficult to relate to the situation 25 years ago. Butterflies were on the decline in Britain, Europe and elsewhere but we lacked data on the extent of the decline and the underlying reasons, leaving us unable to implement effective conservation measures. An early recognition of the plight of British butterflies and moths led to the foundation of the society by a small group of conservationists in 1968. Today the society has over 10000 members, owns a number of reserves and sponsors research, conservation and monitoring activities at the local and national level. As part of the Silver Jubilee celebrations an international symposium was held at Keele University in September 1993 entitled 'Ecology and Conservation of Butterflies'. This symposium clearly showed how much important work has been done in recent years and also gave me the impression that the subject had reached a watershed. This was not because the decline of butterflies has stopped or even slowed down, far from it, the threat to our butterflies continues to increase from habitat destruction and intensification of land use. The watershed is in our understanding of the relationship between butterflies and their habitat.

R4,548 Discovery Miles 45 480 Ships in 10 - 15 working days

This book brings together most of the information available concerning two species that diverged 2-3 million years ago. The objective was to try to understand why two sibling species so similar in several characteristics can be so different in others. To this end, it was crucial to confront all data from their ecology and biogeography with their behavior and DNA polymorphism. Drosophila melanogaster and Drosophila simulans are among the two sibling species for which a large set of data is available. In this book, ecologists, physiologists, geneticists, behaviorists share their data on the two sibling species, and several scenarios of evolution are put forward to explain their similarities and divergences. This is the first collection of essays of its kind. It is not the final point of the analyses of these two species since several areas remain obscure. However, the recent publication of the complete genome of D. melanogaster opens new fields for research. This will probably help us explain why D. melanogaster and D. simulans are sibling species but false friends.

Cyanobacteria have existed for 3.5 billion years, yet they are still the most important photosynthetic organisms on the planet for cycling carbon and nitrogen. The ecosystems where they have key roles range from the warmer oceans to many Antarctic sites. They also include dense nuisance growths in nutrient-rich lakes and nitrogen-fixers which aid the fertility of rice-fields and many soils, especially the biological soil crusts of arid regions. Molecular biology has in recent years provided major advances in our understanding of cyanobacterial ecology. Perhaps for more than any other group of organisms, it is possible to see how the ecology, physiology, biochemistry, ultrastructure and molecular biology interact. This all helps to deal with practical problems such as the control of nuisance blooms and the use of cyanobacterial inocula to manage semi-desert soils. Large-scale culture of several organisms, especially "Spirulina" ("Arthrospira"), for health food and specialist products is increasingly being expanded for a much wider range of uses. In view of their probable contribution to past oil deposits, much attention is currently focused on their potential as a source of biofuel.

Ph.D., Stephen A. Bortone
R1,962 Discovery Miles 19 620 Ships in 12 - 17 working days

Interrelationships Between Corals and Fisheries is derived from a workshop held by the Gulf of Mexico Fishery Management Council in Tampa, Florida in May 2013, where world authorities came together to discuss the current problems in managing tropical fisheries and offered suggestions for future directions for both researchers and environmental resource managers. This book addresses current and emerging threats as well as challenges and opportunities for managing corals and associated fisheries. It provides an information baseline toward a better understanding of how corals and the consequences of coral condition influence fish populations, especially as they relate to management of those populations. The book contains content from presentations modified as a result of interactions and discussions with colleagues and peer reviews by global experts in corals and fisheries. Many chapters include additional materials not presented in the workshop. There are also papers that were not presented at the workshop but contribute to the central theme of the book. Topics covered include: Global decline in coral reefs and impacts on fishery yields Distribution and diversity in the Gulf of Mexico Implementation of Coral Habitat Areas of Particular Concern (CHAPCs) Deepwater coral/sponge habitats Coral populations on offshore platforms Mangrove connectivity for sustaining coral reef fisheries Restoring deepwater coral ecosystems and fisheries after the Deepwater Horizon oil spill Predictive mapping of coral reef fish Covering a range of subject matter, most of the chapters offer suggestions for future research on the interrelationships between corals and fisheries. In addition, the final chapter presents a summary on these interrelationships and discusses managing them for the future.

The fifth and last Volume of this IPMD series reviews, in a multi-disciplinary approach, recent achievements in crop protection and integrated management of arthropod pests. The volume is organized in a first Section covering IPM in citrus productions, a Second one dealing with advacements in the integratioon of management technologies and a last Section covering mites and their biological control agents. As for the previous volumes, we attempted to provide an informative coverage for a broad range of agricultural systems and situations. The chapters are mainly organized and centered on crops, with a particular emphasis on citrus. This is one of the main crops in which biological control and IPM approaches were tested successfully, and the experience gained herein may indeed result helpful for IMP efforts deployed worldwide on other crops and/or cropping systems. Chapters in Section 2 review the integration of insect and disease management options in pecan crops, the application of remote sensing technologies, the status of knowledge about plant defense compounds and their potentials. For IPM of invasive species, an update is provided on the experience gained on the Red Palm Weevil (RPW) in Egypt. Long-term technological solutions for IPM in forests and park areas through aerial treatments with Bt spores concludes this Section. Finally, in Section 3, updated reviews about biological control agents of mites are provided.

One of the classic works of marine biology, a favorite for generations, has now been completely revised and expanded. "Between Pacific Tides" is a book for all who find the shore a place of excitement, wonder, and beauty, and an unsurpassed introductory text for both students and professionals.
This book describes the habits and habitats of the animals that live in one of the most prolific life zones of the world--the rocky shores and tide pools of the Pacific Coast of the United States. The intricate and fascinating life processes of these creatures are described with affectionate care. The animals are grouped according to their most characteristic habitat, whether rocky shore, sandy beach, mud flat, or wharf piling, and the authors discuss their life history, physiology, and community relations, and the influence of wave shock and shifting tide level.
Though the basic purpose and structure--and much of the text--of the book remain the same, content has been increased by about 20 percent; a multitude of changes and additios has been made in the text; the Annotated Systematic Index and General Bibliography have been updated and greatly expanded (now almost 2,300 entries); more than 200 new photographs and drawings have been incorporated; and an entirely new chapter has been added--a topical presentation of the several factors influencing distribution of organisms along the shore. This edition also includes John Steinbeck's Foreword to the 1948 edition.

The small fruit fly, Drosophila melanogaster, has for over a century now had a large impact on biological and biomedical research; however, our knowledge of the fly brain has lagged significantly behind our understanding of other aspects of its development, physiology, and function. In The Making and Un-Making of Neuronal Circuits in Drosophila, innovative expert neuroscientists in the field present the ideas and concepts behind the methods, tools, and tricks that are currently being utilized to decode the secrets of this valuable insect's brain. Focused on the concept of a neuronal circuit, defined as a series of synaptically connected neurons subservient to a particular behavioral modality, this volume contains chapters dealing with anatomical analysis with a focus on cellular and sub-cellular morphologies. These detailed approaches fall under the headings of "Physiology" and "Behavior", conveniently divided the book into two sections. Written in the easy-to-follow Neuromethods series format, this work provides the kind of detailed description and implementation advice that is crucial for getting optimal results. Inventive and accessible, The Making and Un-Making of Neuronal Circuits in Drosophila provides the information and tools necessary to carry out current experiments and, more importantly, further advance the progress of the Drosophila neurobiology field and neurobiology in general.

Among the highlights of this book is the use of novel insecticides acting on a specific site in an insect group and are compatible with natural enemies and the environment. One of such approaches is based on disrupting the activity of biochemical sites acting on transcription factors such as the Helix-Loop-Helix (bHLH) family, anti juvenile hormone (AJH) agents that target JH biosynthetic enzymes, G-protein coupled receptors (GPCR) and bursicon as a target for insect control. Another one is the biotechnology or the genetic approach such as gene silencing (RNA interference) and Bt-crops. Other sections of the book are devoted to the plant s natural products, optical manipulation and the use of nanotechnology for improving insect control methods."

Global warming and globalization are the buzzwords of our time. They have nearly reached a religious status and those who deny their existence are considered modern heretics. Nevertheless, the earth has become an overcrowded village, traversable within a single day. Thus it is hardly surprising that besides persons and goods also agents of disease are easily transported daily from one end of the world to the other, threatening the health and lives of billions of humans and their animals. Agents of diseases (prions, viruses, bacteria, fungi and parasites) are not only transmitted by body contact or direct exchange of bodily fluids, but also by means of vectors which belong to the groups of licking or blood-sucking arthropods (mites, ticks, insects) that live close to humans and their houses.

Without a doubt the recently accelerating globalization supports the import of agents of disease into countries where they never had been or where they had long since been eradicated, leading to a false sense of living on a safe island. These newly imported or reintroduced diseases called emerging diseases may lead to severe outbreaks in cases where the countries are not prepared to combat them, or in cases where viruses are introduced that cannot be controlled by medications or vaccines.

Arthropods are well known vectors for the spread of diseases. Thus their invasion from foreign countries and their spreading close to human dwellings must be blocked everywhere (in donor and receptor countries) using safe and effective measures.

This book presents reviews on examples of such arthropod-borne emerging diseases that lurk on the fringes of our crowded megacities. The following topics show that there is an ongoing invasion of potential vectors and that control measures must be used now in order to avoid disastrous outbreaks of mass diseases.
