Invertebrate Conservation and Agricultural Ecosystems explores the diverse interests of invertebrate conservation and agricultural production. It is both an introduction to invertebrate conservation biology for agriculturists and an introduction to crop protection for conservation biologists, demonstrating how these two disparate fields may draw on each other for greater collective benefit. It draws on recent literature to show how invertebrate conservation in highly altered landscapes may be promoted and enhanced. The book deals with problems of, and approaches to, invertebrate conservation in highly managed agricultural ecosystems, and how biodiversity may be promoted without compromising agricultural production. It draws attention to the importance of invertebrates in agricultural systems and their role in ecosystem functions.
This book will serve as a valuable source of information on the aspects of history, current scenario, non-mulberry cultivation, pruning, pests and diseases of eri, tasar and muga, silkworm rearing, pests and diseases of non-mulberry silkworm, processing of cocoon etc. This book can be used as resource material and practical guide for the students of agriculture, horticulture and sericulture. Note: T&F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.
Honeybees are an important link in our food chain because they are major pollinators of food crops. In recent years, honeybee populations have declined precipitously perhaps due to changes in their microbiome. This book describes and identifies the bee microbiome using a proteomics technology. Chapters include the detection and identification of microbes found in honeybees collected around the United States. This book contains new data and illustrates the rich diversity of microbes as collected by honeybees. It is a must read for everyone concerned about the honeybee and working in the industry.
Although the ancestral home of chelicerates was the sea, the vast majority of modern species live on land. Most students of spiders and mites also restrict themselves to terrestrial habitats. However, a surprising number of mites (Arachnida: Acari) have returned to a watery existence. Approximately 7000 species from the Mesostigmata, Astigmata, Oribatida, and especially the Prostigmata, now live in marine and freshwater habitats. In Aquatic Mites, a dozen chapters explore the distribution, ecology, behavior, genetics, and evolution of the most diverse of these astonishing arachnids. The results of these studies raise as many interesting questions as they answer, and should provoke more investigations of the biology of freshwater and marine Acari.
Despite their enormous bulk and complexity of architecture, plants make up only around a quarter of a million of the 8 million or so species on Earth. The major components of biodiversity, instead, are the smaller, largely unseen, silent majority of invertebrates - most of which are arthropods. Vertebrates, a mere blip on the biotic horizon, are elevated in importance in the bigger scheme of things only by the human psyche.This collection of more than 30 peer-reviewed papers focuses on the diversity and conservation of arthropods, whose species inhabit virtually every recess and plane - and feature somewhere in virtually every food web - on the planet. Highlighting issues ranging from large-scale disturbance to local management, and from spatial heterogeneity to temporal patterns, these papers reflect some of the most exciting new research taking place today - and in some of the most biodiverse corners of the planet.
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.
The history of pathogens and vectors, unique symptoms of diseases and economic importance of important viral diseases have been dealt with in the introductory chapter of this book. While highlighting the role of arthropods, nematodes, and fungi; other agents of the spread of plant pathogens have also been included. Important aspects of insect vectors with direct bearing on transmission, i.e. vector identification, biology, feeding apparatus, and mechanism of spread including control of pathogens through vectors are covered comprehensively. As aphids and other hemipterous insects are major insect vectors, the book stresses on this order. There is a focus on the transmission of determinants under different categories of the transmission mechanism. The transmission determinant paradigm comprising coat protein and helper component has been expounded with recent cases. A brief description of new diseases at least one from each genus of plant viruses has been included in this compendium to elucidate the interaction of vector and virus. Phytoplasmal etiology of pathogens has been detailed separately on account of their importance. The transmission of plant viruses through insects with biting and chewing type of mouth parts has been discussed in detail as separate chapter. The latest research in the field of mites, nematodes, and fungi as vectors of plant viruses has been included. How the phytotoxemia is different from other crop disorders, has been critically explained with support from suitable and common examples of crop disorders. The book also highlights the effects of plant viruses on their vectors. An account of classification of plant viruses has also been given for better understanding of subject matter. Likewise, the information on the electron microscope along with its use has been included so as to define the procedure of examining sub-microscopic entities. The latest developments in the management of plant pathogens through vector management have been discussed with special reference to the use of biotechnology, crop protection, and plant resistance. The book will be of value to the teachers and to researchers. It will also be useful for extension workers in managing crop disorders. Students and researchers of entomology, plant pathology, plant protection and virology disciplines will obtain the latest in the field, through this book.
This book recounts the habits of many interesting and unusual exceptions to the rule that insects are typically terrestrial forms of life. It examines the different ways that groups of species have developed modes of existence in or on the surface of water, and gives reasons why the gross morphology of insects is not favorable for life in or near bodies of water, such as wings that fail to function after coming into contact with water, rendering them useless.
Echinoderms and prochordates occupy a key position in vertebrate evolution. The genomes of sea urchin share 70% homology with humans. Researches on cell cycle in sea urchin and phagocytosis in asteroids have fetched Nobel Prizes. In this context, this book assumes immense importance. Echinoderms are unique, as their symmetry is bilateral in larvae but pentamerous radial in adults. The latter has eliminated the development of an anterior head and bilateral appendages. Further, the obligate need to face the substratum for locomotion and acquisition of food has eliminated their planktonic and nektonic existence. Egg size, a decisive factor in recruitment, increases with decreasing depths up to 2,000-5,000 m in lecithotrophic asteroids and ophiuroids but remains constant in their planktotrophics. Smaller (< 18 mm) ophiuroids do not produce a lecithotrophic eggs but larger (> 110 mm) asteroids generate planktotrophic eggs only. Publications on sex ratio of echinoderms indicate the genetic determination of sex at fertilization but those on hybridization, karyotype and ploidy induction do not provide evidence for heterogametism. But the herbivorous echinoids and larvacea with their gonads harboring both germ cells and Nutritive Phagocytes (NPs) have economized the transportation and hormonal costs on gonadal function. Despite the amazing potential just 2 and 3% of echinoderms undergo clonal reproduction and regeneration, respectively. Fission is triggered, when adequate reserve nutrients are accumulated. It is the most prevalent mode of clonal reproduction in holothuroids, asteroids and ophiuroids. However, budding is a more prevalent mode of clonal reproduction in colonial hemichordates and urochordates. In echinoderms, fission and budding eliminate each other. Similarly, autoregulation of early development eliminates clonal reproduction in echinoids and solitary urochordates. In pterobranchs, thaliaceans and ascidians, the repeated and rapid budding leads to colonial formation. Coloniality imposes reductions in species number and body size, generation time and life span, gonad number and fecundity as well as switching from gonochorism to simultaneous hermaphorditism and oviparity to ovoviviparity/viviparity.
Insects have evolved very unique and interesting tactics using chemical signals to survive. Chemical ecology illustrates the working of the biological network by means of chemical analyses. Recent advances in analytical technology have opened the way to a better understanding of the more complicated and abyssal interactions of insects with other organisms including plants and microbes. This book covers recent research on insects and chemical communications and presents the current status about challenges faced by chemical ecologists for the management of pests in agriculture and human health.
This book presents a 360-degree picture of the world of insects and explores how their existence affects our lives: the "good, bad, and ugly" aspects of their interactions with humankind. It provides a lucid introductory text for beginning undergraduate students in the life sciences, particularly those pursuing beginner courses in entomology, agriculture, and botany.
This book is perhaps the first attempt to comprehensively project the uniqueness of molluscs, covering almost all aspects of reproduction and development from aplacophorans to vampyromorphic cephalopods. Molluscs are unique for the presence of protective external shell, defensive inking, geographic distribution from the depth of 9,050 m to an altitude of 4,300 m, gamete diversity, the use of nurse eggs and embryos to accelerate the first few mitotic divisions in embryos, the natural occurrence of androgenics in a couple of bivalves, viable induced tetraploids, gigantism induced by elevated ploidy, the complementary role played by mitochondrial genome in sex determination by nuclear genes and the uptake and accumulation of steroid hormone from surrounding waters. In molluscs, sexuality comprises of gonochorism (< 75 %) and hermaphroditism, which itself includes simultaneous (> 24%), protandry (< 1 %), Marian and serial. In them, the presence of shell affords iteroparity and relatively longer life span in prosobranchs and bivalves but its absence semelparity and short life span in opisthobranchs and cephalopods. Within semelparity, gonochorism facilitates faster growth and larger body size but hermaphroditism small body size. In them, sex is irrevocably determined at fertilization by a few unknown genes and is not amenable to any environmental influence. However, the sex determining mechanism is more a family trait in bivalves. Primary sex differentiation is also fixed and not amenable to environmental factor but secondary differentiation is labile, protracted and amenable to environmental factors. Both sex differentiation and reproductive cycle are accomplished and controlled solely by neurohormones. In these processes, the role of steroid hormones may be alien to molluscs.
This comprehensive volume focuses exclusively on sea snails (or gastropods), which are popular food items and occupy an important role in the commercial shell craft industry. Familiar examples include conchs (highly sought after due to their mild flavor) and escargot, abalone, and periwinkle snails. This book covers the profile (habitat, distribution, morphology, food and feeding, reproduction, conservation status, etc.) of about 180 species of commercial edible marine gastropod molluscs as well as their nutritional values, commercial importance, and pharmaceutical value. Also included is information on their prevalent diseases and parasites. The informative descriptions are presented in an easy-to-read style with neat illustrations.
The Mollusca, Volume 7: Reproduction presents the significant features of reproduction for one of the significant major molluscan groups. This book reviews the reproductive biology of land snails, which offers the basis for making fascinating comparisons with other terrestrial groups in illustrating how evolutionary various groups solved their common problem of laying eggs. Organized into six chapters, this volume begins with an overview of the reproductive biology of prosobrach gastropods. This text then provides a comparative morphology of land snail reproductive anatomy. Other chapters consider the endocrine control of the female reproductive activity of Lymnaea stagnalis. This book discusses as well the transition in intraspecific and interspecific sexuality. The final chapter deals with cephalopod reproductive biology. This book is a valuable resource for readers who are in need of more appropriate animal systems for solving research problems pertaining to general reproduction, cytology, sex determination, biochemistry, gamete biology, neuroendocrinology, and evolutionary biology.
Arthropod pests cause huge annual losses in global crop production and transmit a number of infectious diseases. The control of such pests is therefore of the utmost importance. This text provides an up-to-date, detailed overview of current approaches including chemical pest control, the use of biological and biorational control agents, and the latest developments in biotechnology. While an introductory text for students in the fields of pest control, entomology, crop protection, and agricultural and environmental sciences, the volume is also aimed at professional pest control practitioners and government employees in extension services.
The book introduces basic entomology, emphasising perspectives on insect diversity important in conservation assessment and setting priorities for management, as a foundation for managers and others without entomological training or background. It bridges the gap between photographic essays on insect identification and more technical texts, to illustrate and discuss many aspects of taxonomic, ecological and evolutionary diversity in the Australian insect fauna, and its impacts in human life, through outlines of many aspects of insect natural history.
Imagine scientists controlling the transmission of certain diseases through the genetic modification of mosquitoes. Eradicating harmful insects without the use of pesticides. Or increasing the fertility of some insects who in turn eat harmful arthropods or even a plant pathogen. Those are just a few of the real-world applications of insect transgenesis, which offers substantial benefits to humankind-whether it be in improving agricultural productivity or reducing the spread of insect-vectored diseases. Insect Transgenesis: Methods and Applications is the first publication to describe in a comprehensive manner the various methodologies available, possible applications, and the risk assessment and regulatory issues involved in this fascinating area of research. Divided into several areas of interest, the book starts with an overview of the history and methodology of insect gene transfer. The book then examines gene targeting by homologous recombination and recombination systems, and systems for transgenic selection, including visible eye color markers, chemical resistance, and fluorescent proteins. Other sections consider the use of various vector systems to integrate DNA into a host genome or to express foreign genes in a host organism. The work concludes with strategies for the use of transgenic insects, including examples for agricultural pests and vectors of disease. Of particular interest are the final chapters that discuss risk assessment considerations and governmental regulatory procedures for the transport and release of transgenic insects.
The first International Conference on Horseshoe Crab's Conservation conducted at Dowling College, USA, (2007) and it's proceedings published by Springer in 2009, prompted the continued research and conservation efforts presented at subsequent conferences and colloquium in Hong Kong, Taiwan, (2011); San Diego, CA, (2014), (CERF); Japan, Sasebo (2015) and an accepted inclusion for a special session on Horseshoe Crabs at the 2017 CERF Conference held in Providence, RI, USA. All these aforementioned conferences contributed manuscripts, posters, workshop "position papers", and oral presentations the majority of which have not been published in total. In 2015, Carmichael et al. had published by Springer the majority of manuscripts from the 2011 Hong Kong / Taiwan conference. However, workshop results and all subsequent presentations and workshops were not. The Japan conference presented over 40 papers alone. A collection of all workshop summaries, poster presentations and new manuscript submittals (San Diego, CA; Sasebo, Japan; and Providence, RI) as well as products prepared for the IUCN World Congress in Hawaii, (2016), are included potential contributions for review in this compilation now available for global distribution in this Springer Nature publication.The "Proceedings of International Conferences on the Biology and Conservation of Horseshoe Crabs", thus contains over 50 manuscripts and a diversified collection of documents, photos and memorabilia covering all four of the horseshoe crab species globally: their biology, ecology evolution, educational, and societal importance. This book exposes the impacts that humans have imposed on all four of these species, revealing through the coordinated effort of horseshoe crab scientists with the IUCN, of the worldwide need for a clear conservative effort to protect these paleo- survival organisms from a looming extinction event. Biologists, conservationists, educators, and health professionals will all welcome this book not only for exploration of its pharmacological interest, but also for the mystery of their longevity. This book also clarifies the future research needs and the conservation agenda for the species worldwide. Anyone working or studying estuaries on a global scale, will need to obtain this seminal work on horseshoe crabs.
This specially curated collection features three reviews of current and key research on climate change, insect pests and invasive species. The first chapter reviews the impact of climate change on insect pests and how it has affected insect pest development and population dynamics, activity and abundance, diversity and geographical distribution. It also assesses insect-host plant interactions and the effectiveness of crop pest management techniques. The second chapter discusses the literature on the potential impact of climate change on the principal insect pests of wheat, including cereal aphids, Hessian fly, orange wheat blossom midge, cereal leaf beetle and cotton bollworm. It assesses the different methods used to assess likely impacts as well climate change effects on biological control in wheat systems. The final chapter surveys what we know about the ecology of invasive species and potential management strategies. In particular, it assesses how integrated pest management (IPM) needs to evolve to deal with invasive species, particularly in focussing more on monitoring, prevention and rapid response.
Members of the phylum Echinodermata are among the most familiar marine invertebrates. Forms such as the sea star have become virtually a symbol of sea life. Used in ancient oriental medicine as a source of bioactive compounds, sea cucumbers, sea stars and sea urchins are now used for the extraction and purification of cytotoxic, haemolytic, antiviral, antifungal, antifouling, antimicrobial and even anti-tumoural activities. In addition, of the five extant classes, sea urchins and sea cucumbers are important economic resources for current fishery and aquaculture. Molecular and cell biological techniques described in this book are, on the one hand, indicative of the improvements made over the years and, on the other, stress the need of their further exploitation for the sustainable production of bioactive compounds and their application in biomedicine.
Cockroaches offer a useful and inexpensive alternative to traditional laboratory animals, yet most researchers are unfamiliar with their biology. This unique and comprehensive cockroach handbook is written for everyone from novice to expert. It addresses every aspect of cockroach biology, with a particular emphasis on the neuroendocrine system. Liberally illustrated chapters include such topics as cockroach culture, anatomy, behavior, and various experimental techniques. One of the few available books to provide broad coverage of the neurobiology of a single organism, this second volume is a must for all researchers in biomedical or veterinary fields, as well as for entomologists.
Ants are familiar to every naturalist, ecologist, entomologist, and pest control operator. The identification of the 233 species of Florida ants is technically difficult, and information on Florida ants is dispersed among hundreds of technical journal articles. This book uses detailed and beautiful scientific drawings for convenient identification. To most Florida biologists ants are currently the most inaccessible group of conspicuous and intrusive insects. This book solves the twin problems of ant identification and the extraordinary fragmentation of natural history information about Florida ants. |
