Guardianes del alma: Animales que nos rescatan
by María Victoria GaiardelliConmovedoras historias que revelan por qué son nuestras mascotas las que nos eligen a nosotros para sanar nuestra alma, y no nosotros a ellas, como muchas veces creemos. Todos alguna vez escuchamos historias de personas que dedican su vida a rescatar animales de la calle y del abandono. Pero ¿somos nosotros los que los salvamos, o en realidad son ellos los que vienen a rescatarnos de mil modos? En este libro, María Victoria Gaiardelli recopila una serie de relatos protagonizados por animales que eligieron a seres humanos para sanarlos y cambiarles la vida y se convirtieron en sus guardianes del alma para siempre. El gato adoptado que salvó de la muerte por asfixia a toda una familia, el perro que alertó a una joven sobre la inminente detonación de una bomba, la perra que revirtió los signos vitales de una niña minutos antes de que fuera sometida a una intervención quirúrgica y el caballo que liberó a su dueña del abismo de los ataques de pánico son algunas de esas historias de esperanza y oportunidad. Advertencia: si al leerlas se emocionan, es porque un alma animal se está apoderando de su alma humana. Y es lo mejor que podría pasarles.
Aullidos en el viento: Historias de galgos
by Isabel De EstradaAullidos en el viento está hilvanado por los retratos de esas miradas desesperadas que Isabel se cruzó en sus recorridos por la provincia de Buenos Aires; los ojos tristes y desconfiados, pero también el pequeño destello de esperanza; las aventuras de finales tristes en las que al mismo tiempo las heridas cicatrizan y reaparecen con vitalidad los ladridos y los lengüetazos. Una tarde, Isabel de Estrada recogió a una galga herida que caminaba perdida al costado de la ruta. A partir de aquel encuentro, se abrió ante ella con toda la fuerza del espanto, la desidia y el sufrimiento un mundo que no había conocido hasta el momento: las carreras de galgos, en las que muchos de los perros mueren después de ser descartados o quedan permanentemente dañados, víctimas del hambre, exigencias físicas desmedidas y otros brutales maltratos. Isabel se embarcó en la ardua tarea de dar a conocer estas carreras clandestinas, denunciarlas y trabajar activamente para terminar con ellas. Con la voluntad de salvar a todos esos perros de un destino cruel, creó Fundación Zorba. En el camino compartió momentos felices y desdichados junto con amigos, familiares y compañeros. Los doce cuentos con perros rescatados que componen este libro son historias de redención, humildad y salvación. Pero no solo de ellos, también es la redención y la gratitud de aquellos a quienes cruzárselos en el camino les ha cambiado la vida.

Arthropod Diversity and Conservation in the Tropics and Sub-tropics
by Akshay Kumar Chakravarthy Shakunthala SridharaArthropods are invertebrates that constitute over 90% of the animal kingdom, and their bio-ecology is closely linked with global functioning and survival. Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline. Arthropods constitute a dominant group with 1. 2 million species influencing earth's biodiversity. Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago. Arthropods are closely associated with living and non-living entities alike, making the ecosystem services they provide crucially important. In order to be effective, plans for the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies for in situ and ex situ conservation. This two-volume book focuses on capturing the essentials of arthropod inventories, biology, and conservation. Further, it seeks to identify the mechanisms by which arthropod populations can be sustained in terrestrial and aquatic ecosystems, and by means of which certain problematic species be managed without producing harmful environmental side-effects. This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracing the diversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, it describes in detail the mechanisms of sustaining arthropod ecosystems, services and populations. It addresses the contribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropods from a holistic perspective before addressing conservation issues at large. This book offers a valuable resource for all zoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested in the conservation of biological resources.

Fundamentals of Applied Acarology
by Manjit Singh DhooriaAcarology - the study of mites and ticks, is a subdiscipline of Zoology, and is many times considered in the field of Entomology (the study of insects). Mites and ticks are distributed throughout the world and inhabit almost every ecosystem (both terrestrial and aquatic) including grassland soils. More than 55,000 species of mites and ticks are already described. Mites and ticks directly affects humans as pests of different crops, fruit plants, vegetable crops and field crops; as parasites of human beings, veterinary animals, poultry and pets; pests of stored grains and other products; mushrooms and cheese; and as parasites of honeybees. Mite infestations are responsible for economic losses worth billions of dollars in terms of reduced crop yields and lowered quality of produce. Many species of mites serve as vectors of various plant diseases; some species of ticks cause losses through blood feeding and by transmitting many diseases among man and animals. House-dust mite allergies, and tick bite allergies are also common in many parts of the world. Present Book, "Fundamentals of Applied Acarology," is written keeping in view non-availability of any standard text dealing in different aspects of acarology at one place. Separate chapters in this book are devoted to Importance of Acarology, Historical account, acarine technology, morphology and anatomy of Acari; Feeding, Development and Reproduction. Molecular developments in relation to mites and ticks are also discussed. Role of mites and ticks in Quarantines of plants and animals; forensic/criminal investigations; and importance of accidental acarophagy are discussed in detail. Safe usage of pesticides based on their mode of action (IRAC's Groups), development of acaricide resistance and measures to mitigate it are discussed. Mite pests of fruit trees, vegetable plants, and floricultural plants; field crops; mite problems in greenhouses/polyhouses; and mite problems encountered under organic cultivation of plants; and their management through minimum usage of pesticides are emphasized. Role of different predaceous mites in controlling plant pests like thrips, aphids and scale insects is elaborately discussed. Biological control of phytophagous mites is discussed in detail. Different animal parasitic mites and ticks are discussed from veterinary and medical point of view. At the end of each chapter, many important references for further reading; and Electronic References (ER) in the form of youtube links and other weblinks are given to understand fully how these tiny creatures look like; behave, feed and reproduce; nature of damage they cause to plants and animals; and measures to mitigate them. Weblinks will stimulate interest in the readers for more information about different mites and ticks. The knowledge contained in the book may prove as best material for "General and Applied Acarology" course for graduate and post-graduate levels, teachers and researchers in entomology, pest control advisors, professional entomologists, pesticide industry managers, policy planners, and others having interest in mites and ticks.
Mental Health, Mental Illness and Migration (Mental Health and Illness Worldwide)
by Dinesh Bhugra Driss Moussaoui Rachel Tribe Antonio V. VentriglioThis book unravels the mental health challenges of the migrants and the socio economic and cultural conditions that bear on the mental well being. In addition, it covers the measures of intervention that can help the migrants maintain or restore their mental well being. Research included in the book is timely given that there is ever increasing mobility of people which on one hand has led to better livelihoods, but on the other has created conditions of stress for the migrants and their families. As migrants are often found to be hesitant of using the health care facilities in the new place which may be due to the lack of awareness, this book elaborates on the health care facilities, cost issues, stigma, and several other factors.
Industrial Entomology
by OmkarThis book is a compilation of writings focused on conventional and unconventional insect products. Some of these products are commercials successes, while others are waiting to be launched and are the potential produce of the future. In addition to the well known products honey, mulberry silk, and lac, the book primarily concentrates on silk producing insects other than the mulberry silkworm, insects as food, as sources of medicines, pest and weed managers, and as pollinators. The book highlights the all pervasive role of insects in improving human lives at multiple levels. Accordingly, while most books on insects concentrate on how to limit growth in their population, it instead focuses on how to propagate them. In each chapter, the book brings to the fore how insects are far more beneficial to us than their well publicised harmful roles. This book approaches both unconventional and conventional insect products, such as honey, silk and lac in much more depth than the available literature. It investigates different aspects of the production of these insects, such as the related processes, problems and utilities, in dedicated chapters. Because this book deals with the production of insects or their produce, it has been named Industrial Entomology, perhaps the only book that truly reveals the tremendous potential of insects to help humans live better lives. Based on the research and working experience of the contributors, who are global experts in their respective fields, it provides authentic, authoritative and updated information on these topics. The book offers a unique guide for students, teachers, policy planners, small scale industrialists, and government ministries of agriculture and industry across the globe. It will provide a much required stimulus to insect appreciation and generate enthusiasm for research and the broader acceptance for insect produce. Hopefully, it will also present the Indian perspective on these topics to a global readership.
Pet bird diseases and care
by Indranil Samanta Samiran BandyopadhyayThis book provides fundamental information on pet birds, menaces, and advances made in the diagnosis and treatment of menaces. It is the only book covering all species of pet birds, menaces and their individual management. The handful of related books available worldwide are largely outdated and focus on a single species or breed of pet bird. The book encompasses the history of bird keeping, common breeds of birds, their nutritional requirements, list of zoonotic diseases transmitted by birds and guideline for their prevention. It covers infectious, non-infectious clinical and metabolic diseases, and toxicity in detail with a special focus on the history of diseases, etiology, affected hosts, pathogenesis, clinical signs, diagnosis and treatment. Separate chapters detail relevant diagnostic techniques, management and care practices, including updated information. The book offers an invaluable guide for students and teachers in the field of (avian) veterinary medicine, scientists/research scholars working in related fields, and avian medicine practitioners, as well as all those progressive bird owners who want to know the basics of their care and management.
Avian Reproduction: From Behavior to Molecules (Advances in Experimental Medicine and Biology #1001)
by Tomohiro SasanamiThis book provides everything from basic knowledge to the recent understandings of avian reproductive physiology, covering many unique aspects. It will inspire avian biologists as well as researchers in varied fields and will offer important steps towards better fertilization success in birds. In spite of the recent remarkable developments in modern technology, a comprehensive understanding of the reproductive mechanisms is still far in the future due to the diverse reproductive tactics in vertebrates. Birds have highly refined reproductive strategies and some of those strategies are unique to birds. However, together with ongoing progress of the genome analysis of birds and the crying need for further increase in meat and egg production, research on avian reproduction is now accelerating and becoming more important. With contributions by leading scientists, the book explains avian primordial germ cells; the sex-determining mechanism; reproductive endocrinology and immunology; sperm, egg, and egg coat; sperm-egg interaction; polyspermic fertilization; seasonal reproduction; social triggers; hormonal and behavioral changes; broodiness; oviductal sperm storage; and biotechnology. This book is recommended for all researchers and students who are interested in birds or reproduction.
Sheep Production Adapting to Climate Change
by Veerasamy Sejian Raghavendra Bhatta John Gaughan Pradeep Kumar Malik S. M. K. Naqvi Rattan LalThis book presents a compilation of the latest findings from reputed researchers around the globe, covering in detail climate change and its effects on sheep production. In the current global climate change scenario, information related to its impact on livestock agriculture is lacking. The negative impacts of climate change are already being felt by all livestock species. Further, the mitigation and amelioration strategies that are applicable for one species may not hold true for another. As such, concerted research efforts are needed to identify species-specific strategies for mitigation and adaptation. With that goal in mind, this book is the first of its kind to gather comprehensive information pertaining to the impact of climate change on various aspects of sheep production. It also sheds light on the role of sheep with regard to the global greenhouse gas pool. The book highlights the status quo of sheep production from climate change perspectives and projects the significance of adapting future sheep production to the challenges posed by climate change. It addresses in detail the various adaptations, methane mitigation and amelioration strategies needed to sustain sheep production in the future. In addition, the book presents development plans and policies that will allow the sheep industry to cope with current climate changes and strategies that will lessen future impacts. Bringing together essential information prepared by world-class researchers hailing from different agro-ecological zones, this book offers a unique resource for all researchers, teachers and students associated with sustaining the sheep production in the face of global change.
Methods For Monitoring Tiger And Prey Populations
by K. Ullas Karanth James D. NicholsThis book addresses issues of monitoring populations of tigers, ungulate prey species and habitat occupancy, with relevance to similar assessments of large mammal species and general biodiversity. It covers issues of rigorous sampling, modeling, estimation and adaptive management of animal populations using cutting-edge tools, such as camera-traps, genetic identification and Geographic Information Systems (GIS), applied under the modern statistical approach of Bayesian and likelihood-based inference. Of special focus here are animal survey data derived for use under spatial capture-recapture, occupancy, distance sampling, mixture-modeling and connectivity analysees. Because tigers are an icons of global conservation, in last five decades,enormous amounts of commitment and resources have been invested by tiger range countries and the conservation community for saving wild tigers. However, status of the big cat remains precarious. Rigorous monitoring of surviving wild tiger populations continues to be essential for both understanding and recovering wild tigers. However, many tiger monitoring programs lack the necessary rigor to generate the reliable results. While the deployment of technologies, analyses, computing power and human-resource investments in tiger monitoring have greatly progressed in the last couple of decades, a full comprehension of their correct deployment has not kept pace in practice. In this volume, Dr. Ullas Karanth and Dr. James Nichols, world leaders in tiger biology and quantitative ecology, respectively, address this key challenge. The have collaborated with an extraordinary array of 30 scientists with expertise in a range of necessary disciplines - biology and ecology of tigers, prey and habitats; advanced statistical theory and practice; computation and programming; practical field-sampling methods that employ technologies as varied as camera traps, genetic analyses and geographic information systems. The book is a 'tour de force' of cutting-edge methodologies for assessing not just tigers but also other predators and their prey. The 14 chapters here are lucidly presented in a coherent sequence to provide tiger-specific answers to fundamental questions in animal population assessment: why monitor, what to monitor and how to monitor. While highlighting robust methods, the authors also clearly point out those that are in use, but unreliable. The managerial dimension of tiger conservation described here, the task of matching monitoring objectives with skills and resources to integrate tiger conservation under an adaptive framework, also renders this volume useful to wildlife scientists as well as conservationists.
Breeding Insect Resistant Crops for Sustainable Agriculture
by Ramesh Arora Surinder SandhuThis book reviews and synthesizes the recent advances in exploiting host plant resistance to insects, highlighting the role of molecular techniques in breeding insect resistant crops. It also provides an overview of the fascinating field of insect-plant relationships, which is fundamental to the study of host-plant resistance to insects. Further, it discusses the conventional and molecular techniques utilized/useful in breeding for resistance to insect-pests including back-cross breeding, modified population improvement methods for insect resistance, marker-assisted backcrossing to expedite the breeding process, identification and validation of new insect-resistance genes and their potential for utilization, genomics, metabolomics, transgenesis and RNAi. Lastly, it analyzes the successes, limitations and prospects for the development of insect-resistant cultivars of rice, maize, sorghum and millet, cotton, rapeseed, legumes and fruit crops, and highlights strategies for management of insect biotypes that limit the success and durability of insect-resistant cultivators in the field. Arthropod pests act as major constraints in the agro-ecosystem. It has been estimated that arthropod pests may be destroying around one-fifth of the global agricultural production/potential production every year. Further, the losses are considerably higher in the developing tropics of Asia and Africa, which are already battling severe food shortage. Integrated pest management (IPM) has emerged as the dominant paradigm for minimizing damage by the insects and non-insect pests over the last 50 years. Pest resistant cultivars represent one of the most environmentally benign, economically viable and ecologically sustainable options for utilization in IPM programs. Hundreds of insect-resistant cultivars of rice, wheat, maize, sorghum, cotton, sugarcane and other crops have been developed worldwide and are extensively grown for increasing and/or stabilizing crop productivity. The annual economic value of arthropod resistance genes developed in global agriculture has been estimated to be greater than US$ 2 billion Despite the impressive achievements and even greater potential in minimizing pest- related losses, only a handful of books have been published on the topic of host-plant resistance to insects. This book fills this wide gap in the literature on breeding insect- resistant crops. It is aimed at plant breeders, entomologists, plant biotechnologists and IPM experts, as well as those working on sustainable agriculture and food security.

Transgenic Ascidians (Advances In Experimental Medicine And Biology #1029)
by Yasunori SasakuraThis book comprehensively describes the transgenesis techniques and applied experimental methods in ascidians including enthusiastically developed original devices in addition to concrete examples of developmental biology studies. Ascidians have been one of the most important model animals in developmental biology for studying molecular and cellular processes underlying formation of the chordate body plan. Transgenic techniques such as microinjection, electropolation, cis-element analysis and application, and TALENs and CRISPR/Cas9 have been developed in ascidians for more than 20 years, and now many applied methods, some of which are unique in ascidians, have been accumulated. Those extensive technological innovations, such as cell isolation, cell labeling, germ-line transformation, marker transgenic lines, and the experimental systems for studying notochord formation and nervous system, are exceptional particularly in marine invertebrates. This book is useful for ascidian researchers to quickly access the techniques in which they are interested as well as to compare each technology to become familiar with specialized tips, and for biologists of other organisms to learn the unique techniques and ingenious attempts specific to ascidians. Providing detailed and easily understandable descriptions of techniques, the book will inspire ascidian specialists to improve their techniques, encourage anyone wanting to begin studying ascidians, and enable readers to immediately apply the techniques to the organisms they research.
Basic and Applied Phytoplankton Biology
by Perumal Santhanam Ajima Begum Perumal PachiappanThis book presents the latest developments and recent research trends in the field of plankton, highlighting the potential ecological and biotechnological applications. It critically and comprehensively discusses strain selection, growth characteristics, large-scale culturing, and biomass harvesting, focusing on the screening and production of high-value products from algae, and evaluating carbon dioxide sequestration from fuel gas as a climate change mitigation strategy. The latter areas of research are clearly central to the sustainable development approach that is currently attracting global attention.Over the decades, much of the literature on has focused on the biological and ecological aspects of phytoplankton found in freshwater, marine and brackish water environments. However, these organisms are known to also inhabit various other environments. More recently, there has been a substantial shift toward the concept of sustainable development and the “green economy” with emphasis on exploiting biological systems for the benefit of mankind. The significance of these plankton cannot be underestimated as they contribute approximately 40% of the oxygen in the atmosphere. Therefore, there is potential for exploitation of this invaluable biomass source that could lead to significant environmental and economic benefits for man.Providing a comprehensive outline of the most recent developments and advances in the field of industrial applications of these plankton, this book is an excellent reference resource for researchers and practitioners.
Basic and Applied Zooplankton Biology
by Perumal Santhanam Ajima Begum Perumal PachiappanThe coastal and ocean ecosystem is a significant feature of our planet and provides a source of food for much of life on Earth. Millions of species have been, and are still being discovered in the world’s oceans. Among these zooplankton serve as secondary producers and are significant as they form pelagic food links and act as indicators of water masses. They constitute the largest and most reliable source of protein for most of the ocean’s fishes. As such, their absence or depletion often affects fishery. In many countries, the decline in fishery has been attributed to reduced plankton populations. Furthermore, trillions of tiny copepods produce countless faecal pellets contributing greatly to the marine snow and therefore accelerating the flow of nutrients and minerals from the surface waters to the seabed. They are phylogenetically highly successful groups in terms of phylogenetic age, number of living species and success of adaptive radiation. A study of the basic and applied aspects of zooplankton would provide an index of the fishery potential and applications, offering insights into ocean ecology to safeguard food supplies and livelihoods of the millions of people living in coastal areas. For this reason, we need to understand all the facets of zooplankton as well as their interactions with atmosphere and other life forms, including human. In this context, this book discusses the basic and applied aspects of zooplankton, especially taxonomy, mosquitocidal activity, culture, analysis of nutritional, pigments and enzyme profile, preservation of copepods eggs, bioenrichment of zooplankton and application of zooplankton in sustainable aquaculture production, focusing on novel biofloc-copefloc technologies, and the impact of acidification and microplastics on zooplankton.Offering a comprehensive overview of the current issues and developments in the field of environmental and commercial applications, this book is a valuable resource for researchers, aquaculturists, environmental mangers wanting to understand the importance of zooplankton and develop technologies for the sustainable production of fish and other commodities to provide food and livelihoods for mankind.

Asian Beekeeping in the 21st Century
by Geoffrey Williams Peter Neumann Panuwan ChantawannakulFrom the perspective of local scientists, this book provides insight into bees and beemanagement of Asia, with a special focus on honey bees.Asia is home to at least nine honey bee species, including the introduced European honeybee, Apis mellifera. Although A. mellifera and the native Asian honey bee, Apis cerana,are the most commonly employed species for commercial beekeeping, the remainingnon-managed native honey bee species have important ecological and economic roleson the continent. Species distributions of most honey bee species overlap in SoutheastAsia, thus promoting the potential for interspecies transmission of pests and parasites,as well as their spread to other parts of the world by human translocation.Losses of managed A. mellifera colonies is of great concern around the world, includingin Asia. Such global colony losses are believed to be caused, in part, by pests andparasites originating from Asia such as the mite Varroa destructor, the microsporidianNosema ceranae, and several bee viruses.Taking advantage of the experience of leading regional bee researchers, this book providesinsight into the current situation of bees and bee management in Asia. Recentintroductions of honey bee parasites of Asian origin to other parts of the world ensuresthat the contents of this book are broadly relevant to bee scientists, researchers, governmentoffi cials, and the general public around the world.
