The Wisdom of the Hive - The Social Physiology of Honey Bee Colonies (Hardcover, New): Thomas D. Seeley The Wisdom of the Hive - The Social Physiology of Honey Bee Colonies (Hardcover, New)

This book is about the inner workings of one of nature’s most complex animal societies: the honey bee colony. It describes and illustrates the results of more than fifteen years of elegant experimental studies conducted by the author. In his investigations, Thomas Seeley has sought the answer to the question of how a colony of bees is organized to gather its resources. The results of his research—including studies of the shaking signal, tremble dance, and waggle dance, and other, more subtle means by which information is exchanged among bees—offer the clearest, most detailed picture available of how a highly integrated animal society works. By showing how several thousand bees function together as an integrated whole to collect the nectar, pollen, and water that sustain the life of the hive, Seeley sheds light on one of the central puzzles of biology: how units at one level of organization can work together to form a higher-level entity. In explaining why a hive is organized the way it is, Seeley draws on the literature of molecular biology, cell biology, animal and human sociology, economics, and operations research. He compares the honey bee colony to other functionally organized groups: multicellular organisms, colonies of marine invertebrates, and human societies. All highly cooperative groups share basic problems: of allocating their members among tasks so that more urgent needs are met before less urgent ones, and of coordinating individual actions into a coherent whole. By comparing such systems in different species, Seeley argues, we can deepen our understanding of the mechanisms that make close cooperation a reality.

Lords of the Fly - Drosophila Genetics and the Experimental Life (Paperback, New): Robert E. Kohler Lords of the Fly - Drosophila Genetics and the Experimental Life (Paperback, New)
Robert E. Kohler
R1,210 Discovery Miles 12 100 Ships in 10 - 15 working days

The common fruit fly, "Drosophila, " has long been one of the most productive of all laboratory animals. From 1910 to 1940, the center of "Drosophila" culture in America was the school of Thomas Hunt Morgan and his students Alfred Sturtevant and Calvin Bridges. They first created "standard" flies through inbreeding and by organizing a network for exchanging stocks of flies that spread their practices around the world.
In "Lords of the Fly, " Robert E. Kohler argues that fly laboratories are a special kind of ecological niche in which the wild fruit fly is transformed into an artificial animal with a distinctive natural history. He shows that the fly was essentially a laboratory tool whose startling productivity opened many new lines of genetic research. Kohler also explores the moral economy of the "Drosophilists": the rules for regulating access to research tools, allocating credit for achievements, and transferring authority from one generation of scientists to the next.
By closely examining the Drosophilists' culture and customs, Kohler reveals essential features of how experimental scientists do their work.

Oar Feet and Opal Teeth - About Copepods and Copepodologists (Hardcover): Charles B. Miller Oar Feet and Opal Teeth - About Copepods and Copepodologists (Hardcover)
Charles B. Miller
R2,787 Discovery Miles 27 870 Ships in 10 - 15 working days

Oar Feet and Opal Teeth is about free-living copepods and the copepodologists who study them. Copepods are a subclass of the arthropod class Crustacea. They act as dominant herbivores and small predators in the planktonic ecosystems of oceans, estuaries, and lakes. Copepods are likely the largest assemblage of complex animals on earth. These strikingly beautiful small crustaceans are of wide ecological significance and as complex and precisely adapted as insects. Yet few biologists and others interested in animals are familiar with them. In Oar Feet and Opal Teeth, Charles B. Miller introduces these small crustaceans and the scientists devoting their careers to revealing their biology. In twenty-one chapters, Miller details the defining features and general biology of copepods. They typically have four or five pairs of oar-like feet to drive escape jumps. Teeth on mandible extensions are formed with siliceous minerals akin to opal. The first two chapters of the book closely examine the oar feet and mouth parts. Subsequent chapters describe internal anatomy, taxonomy, and many aspects of copepod natural history. Recent evolutionary insights about them are reviewed; those are based on molecular genetics and reach back to the Cambrian explosion. Oar Feet and Opal Teeth includes over twenty biographical sketches of copepodologists from the mid-twentieth century to the present. Among them, Russell Hopcroft, a premier photographer of plankton, has full-color copepod images featured throughout the book. Jeannette Yen learned how Euchaeta marina detects prey and studies how ready-for-mating copepods find each other. Shinichi Uye of Hiroshima University studied the production by copepods of resting eggs and their delayed development. Grace Wyngaard is studying the special embryonic cell-divisions of some lake copepods for eliminating "junk DNA." Miller based most of the profiles featured in the book on personal interviews he conducted.

R7,739 Discovery Miles 77 390 Ships in 18 - 22 working days

The crustaceans are ecologically and economically important organisms. They constitute one of the dominant invertebrate groups on earth, particularly within the aquatic realm. Crustaceans include some of the preferred scientific model organism, profitable aquaculture specimen, but also invasive nuisance species threatening native animal communities throughout the world. Chemoreception is the most important sensory modality of crustaceans, acquiring important information about their environment and picking up the chemical signals that mediate communication with conspecifics. Significant advances have been made in our understanding of crustacean chemical communication during the past decade. This includes knowledge about the identity, production, transfer, reception and behavioral function of chemical signals in selected crustacean groups. While it is well known that chemical communication is an integral part of the behavioral ecology of most living organisms, the intricate ways in which organisms allocate chemicals in communication remains enigmatic. How does the environment influence the evolution of chemical communication? What are the environmental cues that induce production or release of chemicals? How do individuals economize production and utilization of chemicals? What is the importance of molecule specificity or mix of a molecule cocktail in chemical communication? What is the role of chemical cues in multimodal communication? How does the ontogenetic stage, the sex or the physiological status of an individual affect its reaction to chemical cues? Many of these questions still represent important challenges to biologists.

R4,884 Discovery Miles 48 840 Ships in 10 - 15 working days

Many infectious diseases of recent concern, including malaria, cholera, plague, and Lyme disease, have emerged from complex ecological communities, involving multiple hosts and their associated parasites. Several of these diseases appear to be influenced by human impacts on the environment, such as intensive agriculture, clear-cut forestry, and habitat loss and fragmentation; such environmental impacts may affect many species that occur at trophic levels below or above the hostcommunity. These observations suggest that the prevalence of both human and wildlife diseases may be altered in unanticipated ways by changes in the structure and composition of ecological communities. Predicting the epidemiological ramifications of such alteration in community composition will require strengthening the current union between community ecology and epidemiology.

Marisa Anne Bass
R1,498 Discovery Miles 14 980 Ships in 10 - 15 working days

How the nature illustrations of a Renaissance polymath reflect his turbulent age This pathbreaking and stunningly illustrated book recovers the intersections between natural history, politics, art, and philosophy in the late sixteenth-century Low Countries. Insect Artifice explores the moment when the seismic forces of the Dutch Revolt wreaked havoc on the region's creative and intellectual community, compelling its members to seek solace in intimate exchanges of art and knowledge. At its center is a neglected treasure of the late Renaissance: the Four Elements manuscripts of Joris Hoefnagel (1542-1600), a learned Netherlandish merchant, miniaturist, and itinerant draftsman who turned to the study of nature in this era of political and spiritual upheaval. Presented here for the first time are more than eighty pages in color facsimile of Hoefnagel's encyclopedic masterwork, which showcase both the splendor and eccentricity of its meticulously painted animals, insects, and botanical specimens. Marisa Anne Bass unfolds the circumstances that drove the creation of the Four Elements by delving into Hoefnagel's writings and larger oeuvre, the works of his friends, and the rich world of classical learning and empirical inquiry in which he participated. Bass reveals how Hoefnagel and his colleagues engaged with natural philosophy as a means to reflect on their experiences of war and exile, and found refuge from the threats of iconoclasm and inquisition in the manuscript medium itself. This is a book about how destruction and violence can lead to cultural renewal, and about the transformation of Netherlandish identity on the eve of the Dutch Golden Age.

The Discovery of a Visual System - The Honeybee (Hardcover): Adrian Horridge The Discovery of a Visual System - The Honeybee (Hardcover)
Adrian Horridge
R2,714 Discovery Miles 27 140 Ships in 10 - 15 working days

This book is the only account of what honeybees actually see. Bees detect some visual features such as edges and colours, but there is no sign that they reconstruct patterns or put together features to form objects. Bees detect motion but have no perception of what it is that moves, and certainly they do not recognize "things" by their shapes. Yet they clearly see well enough to fly and find food with a minute brain. Bee vision is therefore relevant to the construction of simple artificial visual systems, for example for mobile robots. The surprising conclusion is that bee vision is adapted to the recognition of places, not things. In this volume, Adrian Horridge also sets out the curious and contentious history of how bee vision came to be understood, with an account of a century of neglect of old experimental results, errors of interpretation, sharp disagreements, and failures of the scientific method. The design of the experiments and the methods of making inferences from observations are also critically examined, with the conclusion that scientists are often hesitant, imperfect and misleading, ignore the work of others, and fail to consider alternative explanations. The erratic path to understanding makes interesting reading for anyone with an interest in the workings of science but particularly those researching insect vision and invertebrate sensory systems.

Migration is a key process in the population dynamics of many insects, including some of the most damaging pests. Multidisciplinary research into the importance of migration, in recent decades, has produced many new insights. This book reviews current understanding of the ecological, behavioural, physiological and genetic bases of insect migration. The first part describes migration systems in Europe, Asia, Africa, Australia, and America, with an emphasis on the role of regional weather and climate. The second part considers insects adaptation to migration; it covers: aerodynamics and energetics; the integration of migration in insect life cycles; environmental and genetic regulation of migratory potential; and the evolutionary implications of habitat heterogeneity and variability. The book then addresses the application of this knowledge to operational pest forecasting.

R4,918 Discovery Miles 49 180 Ships in 10 - 15 working days

Mosquitoes are important as transmitters of widespread major diseases and as nuisance insects. They are also one of the most studied and well-known group of insects, both in the laboratory and in the field. The first volume in "The Biology of Mosquitoes" series is a key reference work and has received excellent reviews. This second title in the three volume series focuses on the functioning of the mosquito sense organs that provide them with information about the environment and that enable the adult females to find and attack their vertebrate hosts. It also reviews knowledge of the circadian rhythms and other internal mechanisms that regulate the onset and timing of different behaviors. This integrated review of the sensory mechanisms and behavior of mosquitoes provides a unique insight into their biology. The contents, which are fully up-to-date, include much important work from the past which is often overlooked.

Insect Symbiosis (Hardcover): Kostas Bourtzis, Thomas A. Miller Insect Symbiosis (Hardcover)

R5,082 Discovery Miles 50 820 Ships in 10 - 15 working days

Insect Symbiosis is a collection of chapters written by world authorities on the microbes that can be called symbionts that are associated with insects and mites. Whether bacteria, fungi or spiroplasmids, and whether endosymbionts or casual gut symbionts, the authors describe some of the latest work in a field that has grown rapidly since the development of the newer molecular methods, which allowed for the identification of even minute samples of microbes without the need for culturing.

This reference summarizes the current knowledge of the relationship between symbiotic organisms and their insect hosts and provides an unparalleled analysis of cutting-edge research on this issue. Findings from international experts reveal possible new ways to control disease-carrying insects and agricultural pests worldwide. An examination of Wolbachia, considered by many as a vehicle to deliver anti-malarial and anti-plant virus strategies, is also included. Insect Symbiosis serves as a great reference on host-parasitic relationships for professionals from a broad range of fields.

In this extensive update of his definitive reference, Charles D. Michener reveals a diverse fauna that numbers more than 17,000 species and ranges from the common honeybee to rare bees that feed on the pollen of a single type of plant. With many new facts, reclassifications, and revisions, the second edition of The Bees of the World provides the most comprehensive treatment of the 1,200 genera and subgenera of the Apiformes. Included are hundreds of updated citations to work published since the appearance of the first edition and a new set of plates of fossil bees.

The book begins with extensive introductory sections that include bee evolution, classification of the various bee families, the coevolution of bees and flowering plants, nesting behavior, differences between solitary and social bees, and the anatomy of these amazing insects. Drawing on modern studies and evidence from the fossil record, Michener reveals what the ancestral bee -- the protobee -- might have looked like. He also cites the major literature on bee biology and describes the need for further research on the systematics and natural history of bees, including their importance as pollinators of crops and natural vegetation. The greater part of the work consists of an unprecedented treatment of bee systematics, with keys for identification to the subgenus level. For each genus and subgenus, Michener includes a brief natural history describing geographical range, number of species, and noteworthy information pertaining to nesting or floral biology.

The book is beautifully illustrated with more than 500 drawings and photographs that depict behavior, detailed morphology, and ecology. Accented with color plates ofselect bees, The Bees of the World will continue to be the world's best reference on these diverse insects.

R2,168 Discovery Miles 21 680 Ships in 10 - 15 working days

A number of species of Thysanoptera (thrips) are increasingly important crop pests in many parts of the world, as well as in some cases being vectors of plant disease. Communicating the known information about a species of organism is dependent on our ability to recognize or identify it accurately. This book is a completely revised and rewritten edition of the standard, widely used manual on these minute flying insects written by J.M. Palmer, L.A. Mound and G.J. du Heaume and published in 1989 as "CIE Guides to Insects of Importance to Man 2. Thysanoptera," which provides a practical identification guide on a worldwide scale. The previous version posed problems for students in terms of fluency in English & knowledge of dichotomous keys. However, this thoroughly updated edition incorporates a new set of pictorial keys, which have been developed and used very successfully for training courses at the International Institute of Entomology and which will greatly enhance the ability of the non-specialist to identify thrips to species. Individuals of these insects can usually be identified only by examination under a microscope, often at high power. Within each species, individuals can vary in size, colour and shape and their appearance can be altered by techniques used in preparation. This booklet describes techniques used in the preparation of thrip specimens onto slides for identification and the means of identifying slide-mounted specimens most commonly encountered. It also introduces students to the biological diversity that is found amongst the Thysanoptera, their economic importance in terms of both damaging and beneficial effects, new identification techniques, additional information and taxa, glossary of technical terms, notes on each genus (described alphabetically within their families and subfamilies). Supplementary keys to species are also given within four genera that include several pest species (Caliothrips, Frankliniella, Scirtothrips and Thrips) along with new distribution records which have occurred since the publication of the first edition. It is an essential tool for applied entomologists and crop protection specialists involved in the control of crop pest thrips, and thrip taxonomists.

R5,947 Discovery Miles 59 470 Ships in 18 - 22 working days

As sequel to Aquatic Animal Nutrition - A Mechanistic Perspective from Individuals to Generations, the present treatise on organic macro- and micronutrients continues the unique cross fertilization of aquatic ecology/ecophysiology and aquaculture. This treatise considers proteins and their constituents, carbohydrates from mono- to polysaccharides, fatty acids from free acids to fat, and waxes. It becomes obvious that these organic nutrients are more than only simple fuel for the metabolism of animals; rather, their constituents have messenger and controlling function for the actual consuming individual and even for succeeding generations. This aspect will become particularly clear by putting the organisms under consideration back into their ecosystem with their interrelationships and interdependencies. Furthermore, micronutrients, such as vitamins and nucleotides as well as exogenous enzymes, are in the focus of this volume with known and still-to-be-discovered controlling physiological and biomolecular functions. Aquatic Animal Nutrition - Organic Macro and Micro Nutrients addresses se veral gaps in nutritional research and practice. One major gap is the lack of com mon research standards and protocols for nutritional studies so that virtually incomparable approaches have to be compared. This applies also to the studied animals, since most approaches disregard intraspecific variabilities and the existence of epimutations in farmed individuals. Furthermore, recalling the Mechanistic Perspective from Individuals to Generations, dietary benefits and deficiencies have effects on succeeding generations. In most studies, this long-term and sustainable aspect is overruled by pure short-term production aspects. By comparing nutritional behavior and success of fishes and invertebrates, Aqua tic Animal Nutrition points out different metabolic pathways in these animal groups and discusses how, for instance, fishes would benefit when having some successful metabolic pathway of invertebrates. Application of novel ge ne tic techniques will help turn this vision into reality. However, a widely missing link in the current nutritional research is epigenetics regarding transgenerational heritages of acquired morphological and physiological properties. To in crease public acceptance, nutritional optimization of farmed animals based on this mechanism, rather than genetical engineering, appears promising.

This book presents the whole picture of the ecological and evolutionary study on the ground beetle group, the subgenus Ohomopterus of the genus Carabus, endemic to Japan. This flightless beetle group consists of many geographic races. They show divergence in key traits for reproductive isolation-body size and genital morphology, which leads to coexistence of two or more species. This beetle group provides an important material to study how a lineage of organisms diversify and form multi-species assemblage, and thereby multiply their species richness. The book introduces novel genomic approaches to resolve questions about evolution of Ohomopterus. The readers will find that this story of evolution in Carabus beetles revealed by recent approaches is much different from what was told in previous literature. Exploring different cases across a wide range of lineages is important in constructing a synthetic theory of species radiation and richness, including speciation and species coexistence. This study on Ohomopterus beetles contributes to the ongoing discussion to understand how and why species multiply and how species richness increases in one area of our planet.
