R631 R575 Discovery Miles 5 750 Save R56 (9%) Ships in 18 - 22 working days

Entomologist Justin O. Schmidt is on a mission. Some say it's a brave exploration, others shake their heads in disbelief. His goal? To compare the impacts of stinging insects on humans, mainly using himself as the gauge. In The Sting of the Wild, the colorful Dr. Schmidt takes us on a journey inside the lives of stinging insects, seeing the world through their eyes as well as his own. He explains how and why they attack and reveals the powerful punch they can deliver with a small venom gland and a "sting," the name for the apparatus that delivers the venom. We learn which insects are the worst to encounter and why some are barely worth considering. The Sting of the Wild includes the complete Schmidt Sting Pain Index, published here for the first time. In addition to a numerical ranking of the agony of each of the eighty-three stings he's sampled so far (from below 1 to an excruciatingly painful 4), Schmidt describes them in prose worthy of a professional wine critic: "Looks deceive. Rich and full-bodied in appearance, but flavorless" and "Pure, intense, brilliant pain. Like walking over flaming charcoal with a three-inch nail embedded in your heel." Schmidt explains that, for some insects, stinging is used for hunting: small wasps, for example, can paralyze huge caterpillars and then lay their eggs inside so that their larvae can feast within. Others are used to kill competing insects, even members of their own species. Humans usually experience stings as defensive maneuvers used by insects to protect their nest mates. With colorful descriptions of each venom's sensation and a story that leaves you tingling with awe, The Sting of the Wild's one-of-a-kind style will fire your imagination.

Howard B. Feldman
R2,515 Discovery Miles 25 150 Ships in 10 - 15 working days

This book consists of a series of papers that help to unravel the taxonomy of the phylum Brachiopoda and describe associated marine communities in the Levant. These faunas inhabited shallow shelf environments near the boundary of the Indo-African and Tethyan faunal realms near the Jurassic equator along the southern Tethyan margin. This research is part of a long term project that aims to delineate the distribution of brachiopods across faunal realm boundaries and reconstruct the biogeographic history of the region. The work provides a more detailed analysis of the endemism that is characteristic of the faunas of northern Sinai, the Negev and Jordan, and will also aid in the construction of a biogeographic framework for Jurassic strata in the Middle East. It represents an important contribution to our knowledge of the evolution of modern marine communities because their roots lie in the ecological diversifications of the Jurassic.

The Ecology of Malaria Vectors (Hardcover): Jacques Derek Charlwood The Ecology of Malaria Vectors (Hardcover)

Covering all aspects from classification and systematics, population dynamics, vector control, to surveillance and sampling, epidemics, and a selection of case histories, the book also considers genetics and resistance, Aedes biology, and malaria and dengue models. It is designed to fill the gap between very specialized texts and undergraduate books on general disease vectors, and is ideal as a textbook for postgraduate courses in entomology and mosquito vectors of disease.

Biointensive Integrated Pest Management in Horticultural Ecosystems (Hardcover, 2014 ed.): P. Parvatha Reddy Biointensive Integrated Pest Management in Horticultural Ecosystems (Hardcover, 2014 ed.)
P. Parvatha Reddy
R6,334 Discovery Miles 63 340 Ships in 18 - 22 working days

Through Green Revolution in late 1960s, India achieved self-sufficiency in food production, but still the country has not achieved self-sufficiency in production of horticultural crops. Most of the growth in food production during the green revolution period is attributed to the use of higher levels of fertilizers and pesticides which are continuing to destroy stable traditional ecosystems. The challenge before the crop protection scientist is to increase yields from the existing land without harming the environment and resource base. This can be achieved by adopting eco-friendly Biointensive Integrated Pest Management (BIPM) strategy.

BIPM incorporates ecological and economic factors into agricultural system design and decision making, and addresses public concerns about environmental quality and food safety. The benefits of implementing BIPM can include reduced chemical input costs, reduced on-farm and off-farm environmental impacts, and more effective and sustainable pest management. An ecology-based IPM has the potential of decreasing inputs of fuel, machinery, and synthetic chemicals-all of which are energy intensive and increasingly costly in terms of financial and environmental impact. Such reductions will benefit the grower and society.

The present book deals with the most recent biointensive integrated approaches for pest management utilizing components such as bioagents predators, parasitoids and pathogens (bacteria, fungi, viruses)], botanicals (biofumigation, oil cakes, FYM, compost, crop residues, green manuring and other organic amendments), arbuscular mycorrhizal fungi, physical methods (hot water treatment of planting material, soil solarization), cultural methods (crop rotation, summer ploughing, fallowing, intercropping, pruning, mulching, spacing, planting date, trap cropping, "etc."), biorational chemicals (pheromones) and resistant cultivars. This book can serve as a useful reference to policy makers, research and extension workers, practicing farmers and students. The material can also be used for teaching post-graduate courses."

Because of its peculiar biology, its negative impacts on forestry, and its urticating larvae affecting human and animal health, pine processionary moth has largely been studied in many European countries during the last century. However, knowledge remained scattered and no synthesis has ever been published. Since the IPCC retained the moth as one of the two insect indicators of climate change because of its expansion with warming up, filling this gap became increasingly important. Led by INRA, this book associates 101 authors from 22 countries of Europe, Minor Asia and North Africa, combining all the concerned research fields (entomology, ecology, genetics, mathematical modelling, medical and veterinary science, pest management) in a multidisciplinary approach to understand and model the processes underlying past, present and future moth expansion and to propose adapted management methods. Besides, the major biological patterns of the related processionary species are also detailed.

T. J Pandian
R5,341 Discovery Miles 53 410 Ships in 10 - 15 working days

This book is a concise informative elucidation of all aspects of reproduction and development in annelids covering from arenicola to tubifex. Annelids flourish between 4,900 m depth to 2,000 m altitude; some of them occur in unusual habitats like hydrothermal vents and subterranean aquatic system (stigobionts). A few have no gut and acquire adequate nutrients through osmotrophism and/or engaging symbiotic microbes. In the absence of exoskeleton to escape predation, the 17,000 speciose annelids have explored bewildering modes of reproduction; not surprisingly, 42-47% of them are brooders. With 13,000 species, polychaetes are gonochores but some 207 species of them are hermaphrodites. Clitellates are all hermaphrodites; of them, 76 species are parthenogens, of which 56 are earthworms. Regenerative potency of annelids ranges from an organ to an entire worm from a single 'seminal' segment. The head, tail and both together can be regenerated 21, 42 and 20 times, respectively. However, the potency is limited to ~1% of polychaetes and < 2% of oligochaetes. In oligochaetes, the chloragogue temporally separates regeneration and reproduction but sedentary polychaetes undertake them together at the reduced reproductive output. Only 79 polychaete and 111 oligochaete species have the potency for clonal reproduction. Within families, the potency ranges from 2% in spionids to 54% in naidids. Epitoky, a spectacular and unique phenomenon, involves the transformation from benthic to meroplanktonic reproductive morphism. It occurs in 106 errant polychaete species. The larger glycerides, nereidids and eunicids use muscular energy to climb < 50 m vertical distance. But the small phyllodocids and cteniodrilids may reduce buoyancy to climb 1,000-4,000 m vertical distance. Heterogamatic sex determination is reported to occur only in six polychaete species, although karyotype is known for 83 annelid species. In temperate polychaetes, a dozen neuroendocrines, arising mostly from the 'brain' regulates reproductive cycle. A complete chapter devoted to vermiculture, (i) recognizes the fast-growing candidate species, (ii) distinguishes 'layers' from 'brooders', (iii) indicates that the harvest of oligochaetes may reduce the input of nitrogenous fertilizer in the ricefield, and (iv) explores the scope for increasing wealth from waste.

R3,332 Discovery Miles 33 320 Ships in 18 - 22 working days

This book explores one of the most discussed and investigated novel foods in recent years: edible insects. The increasing demand for alternative protein sources worldwide had led the Food and Agriculture Organization of the United Nations (FAO) to promote the potential of using insects both for feed and food, establishing a program called "Edible Insects." Although several social, environmental, and nutritional benefits of the use of insects in the human diet have been identified, the majority of the population in Western countries rejects the idea of adopting insects as food, predominantly for cultural reasons. Nevertheless, international interest in promoting the consumption of insects has grown significantly, mainly in North America and Europe. This trend is mostly due to increasing attention and involvement from the scientific network and the food and feed industries, as well as governments and their constituents. The book explores the current state of entomophagy and identifies knowledge gaps to inform primary research institutions, students, members of the private sector, and policymakers to better plan, develop, and implement future research studies on edible insects as a sustainable source of food. The case studies and issues presented in this book cover highly up-to-date topics such as aspects of safety and allergies for human consumption, final meat quality of animals fed with insects, the legislative framework for the commercialization of this novel food, and other relevant issues.

Recent research on skin immunity and the skin microbiome reveals the complexity of the skin and its importance in the development of immunity against arthropod-borne diseases. In diseases such as malaria, borreliosis, leishmaniasis, trypanosomiasis, etc., the skin interface has been shown as an essential site for pathogens to hide from the immune system, and as a potential site of persistence. Only very few vaccines have been successfully developed so far against these diseases, likely because of an insufficient understanding on the development of skin immunity against pathogens. Skin and Arthropod Vectors expands our knowledge on the role of the skin interface during the transmission of arthropod-borne diseases and particularly its immunity. This work may support researchers who strive for developing more efficient diagnostic tools and vaccines. It also gives scientists and advanced students working in related areas a better insight on how humans and animals are attractive to arthropods to develop better repellents, or to set up transgenic arthropods.

Peter J. Hayward
R690 Discovery Miles 6 900 Ships in 10 - 15 working days

On rocky coastlines, receding tides leave standing pools that have long held a fascination for the amateur seashore naturalist, revealing glimpses of colourful and curious marine plants and animals. Animal diversity is far greater in the sea than in terrestrial or freshwater habitats, and the hugely varied fauna of rock pools reflects that fact. Rock pools also undergo dramatic shifts in temperature, salinity and pH, making such habitats crucibles of adaptation and change. This Naturalists' Handbook offers a comprehensive introduction to this captivating world, with chapters covering rock-pool ecology, seaweeds, animals, identification and guidelines for possible fieldwork and further study. Also presented are detailed keys to all the main groups likely to be encountered when rockpooling around Britain and Ireland - from sea squirts to chitons, from anemones to sea spiders, from amphipods to fishes. Rock pools is an indispensable tool in discovering these kaleidoscopic habitats and their multitudinous inhabitants.
