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.
Destruction of habitat is the major cause for loss of
biodiversity including variation in life history and habitat
ecology. Each species and population adapts to its environment,
adaptations visible in morphology, ecology, behaviour, physiology
and genetics. Here, the authors present the population ecology of
Atlantic salmon and brown trout and how it is influenced by the
environment in terms of growth, migration, spawning and
recruitment. Salmonids appeared as freshwater fish some 50 million
years ago. Atlantic salmon and brown trout evolved in the Atlantic
basin, Atlantic salmon in North America and Europe, brown trout in
Europe, Northern Africa and Western Asia. The species live in small
streams as well as large rivers, lakes, estuaries, coastal seas and
oceans, with brown trout better adapted to small streams and less
well adapted to feeding in the ocean than Atlantic salmon. Smolt
and adult sizes and longevity are constrained by habitat conditions
of populations spawning in small streams. Feeding, wintering and
spawning opportunities influence migratory versus resident
lifestyles, while the growth rate influences egg size and number,
age at maturity, reproductive success and longevity. Further, early
experiences influence later performance. For instance, juvenile
behaviour influences adult homing, competition for spawning
habitat, partner finding and predator avoidance.
The story of invasive species in New Zealand is unlike any other in the world. By the mid-thirteenth century, the main islands of the country were the last large landmasses on Earth to remain uninhabited by humans, or any other land mammals. New Zealand's endemic fauna evolved in isolation until first Polynesians, and then Europeans, arrived with a host of companion animals such as rats and cats in tow. Well-equipped with teeth and claws, these small furry mammals, along with the later arrival of stoats and ferrets, have devastated the fragile populations of unique birds, lizards and insects. Carolyn M. King brings together the necessary historical analysis and recent ecological research to understand this long, slow tragedy. As a comprehensive historical perspective on the fate of an iconic endemic fauna, this book offers much-needed insight into one of New Zealand's longest-running national crises.
Recent advances in the study of bats have changed the way we understand this illusive group of mammals. This volume consist of 25 chapters and 57 authors from around the globe all writing on the most recent finding on the evolution, ecology and conservation of bats. The chapters in this book are not intended to be exhaustive literature reviews, but instead extended manuscripts that bring new and fresh perspectives. Many chapters consist of previously unpublished data and are repetitive of new insights and understanding in bat evolution, ecology and conservation. All chapters were peer-reviewed and revised by the authors. Many of the chapters are multi-authored to provide comprehensive and authoritative coverage of the topics.
Large ungulates in tropical forests are among the most threatened taxa of mammals. Excessive hunting, degradation of and encroachments on their natural habitats by humans have contributed to drastic reductions in wild ungulate populations in recent decades. As such, reliable assessments of ungulate-habitat relationships and the spatial dynamics of their populations are urgently needed to provide a scientific basis for conservation efforts. However, such rigorous assessments are methodologically complex and logistically difficult, and consequently many commonly used ungulate population survey methods do not address key problems. As a result of such deficiencies, key parameters related to population distribution, abundance, habitat ecology and management of tropical forest ungulates remain poorly understood. This book addresses this critical knowledge gap by examining how population abundance patterns in five threatened species of large ungulates vary across space in the tropical forests of the Nagarahole-Bandipur reserves in southwestern India. It also explains the development and application of an innovative methodology - spatially explicit line transect sampling - based on an advanced hierarchical modelling under the Bayesian inferential framework, which overcomes common methodological deficiencies in current ungulate surveys. The methods and results presented provide valuable reference material for researchers and professionals involved in studying and managing wild ungulate populations around the globe.
This volume critically reviews all previously published work of parasites that interact with krill (order Euphausiacea) updating misconceptions and summarizing the diversity of epibionts, ectoparasites, mesoparasites and endoparasites that interact with these crustaceans. As far as we know, there is a lack of books about parasites of marine crustaceans not targeted to fisheries and aquaculture. Thus, this would be the most complete and integrative monograph of parasites of marine zooplankton and micro nektonic organisms worldwide. Krill form immense aggregations and serve as food for multiple planktonic and nektonic predators playing a crucial role in pelagic food web. Besides, several species are also used for human consumption. For these reasons there is a growing concern about the health issues that krill parasites may impose on other species, including us. This book provides a comprehensive review of parasites of a crustacean order that can extrapolate to potential parasites in other crustacean taxa worldwide.
The Tropics are home to the greatest biodiversity in the world, but tropical species are at risk due to anthropogenic activities, mainly land use change, habitat loss, invasive species, and pathogens. Over the past 20 years, the avian malaria and related parasites (Order: Haemosporida) systems have received increased attention in the tropical regions from a diverse array of research perspectives. However, to date no attempts have been made to synthesize the available information and to propose new lines of research. This book provides such a synthesis by not only focusing on the antagonistic interactions, but also by providing conceptual chapters on topics going from avian haemosporidians life cycles and study techniques, to chapters addressing current concepts on ecology and evolution. For example, a chapter synthesizing basic biogeography and ecological niche model concepts is presented, followed by one on the island biogeography of avian haemosporidians. Accordingly, researchers and professionals interested in these antagonistic interaction systems will find both an overview of the field with special emphasis on the tropics, and access to the necessary conceptual framework for various topics in ecology, evolution and systematics. Given its conceptual perspective, the book will appeal not only to readers interested in avian haemosporidians, but also to those more generally interested in the ecology, evolution and systematics of host-parasite interactions.
This book examines the contents, influence, and potential of a personal selection of modern books published over the last fifty years that have been relevant to improving welfare. The works selected comprise three earlier classics that mainly deal with animal experimentation and intensive farming, as well as five that concentrate on specific subject areas, namely history, science, applied ethics, politics and law, that are important to protecting the welfare of animals against suffering inflicted by humans. The books are arranged in the order of their publication date, and for each one a few related works are also mentioned or discussed. This collection provides a broad understanding of animal protection issues, and provides the necessary basis for an informed and comprehensive approach to improving the welfare of animals. The books selected have been influential and they have the potential to improve animal welfare in the future.
"Insect Behavior" is the second edition of the text that for thirty years served as the fundamental introduction to a field of study that has been growing enormously. Today, new technologies and understandings are allowing questions to be shaped and answered in ways that once could not have been envisioned. However, massive new information also can overwhelm and obscure the broader perspectives needed to put new discoveries into context. Thus, the times fairly demand that students and non-specialists seek a wider understanding of diverse proximate and ultimate forces that cause animals to behave as they do. This book provides that opportunity. The authors strike a balance between modern developments and historical insights, between new examples and old, between empirical work and theory, and between pertinent conclusions and the dynamic field and laboratory experiences from which such discoveries arise. Considerably updated and expanded, this edition includes 26 case studies, as well as 45 new color plates and 173 figures (over 40% of them new) with detailed legends that add richness to the well-written, accessible text. Like the course that originally inspired it, "Insect Behavior" will find utility at the graduate and senior undergraduate level for college and university students. However, although some background in entomology or animal behavior is helpful, an in-depth knowledge is not a prerequisite. Thus, the book also invites comparative psychologists, science educators, and all others with an interest in the physically small but inestimably important creatures that comprise three-quarters of all animal life on our planet.

In a world where habitats are constantly changing and the impact of anthropization on the environment is increasingly intense, interactions between human and wildlife are becoming more and more complex. Some species pose problems for human activities while many others need to be helped in order to continue to exist. This book follows the first volume called 'Problematic Wildlife', edited by F.M. Angelici and published by Springer in 2016, which has had considerable success with readers and critics. The volume includes 21 chapters divided into 7 parts devoted specific topics which are approached in a multidisciplinary way. There are both review chapters and specific cases, always bearing in mind the interest for an international audience. The book is useful both for scientists, wildlife specialists, conservationists, zoologists, ecologists, university students, nature managers, and for those who live in contact with wildlife and its problems, such as farmers, shepherds, hunters, urban planners, and staff of parks and nature reserves. Its ultimate goal is to offer scientific and pragmatic approaches to manage each categories of problematic species.
Originally published in 1975 Terrestrial Environments covers the zoogeography and ecology of the main terrestrial environments of the world, including fresh water habitats with emphasis on their fauna. The book also explores climate and vegetation in so far as they affect animal life. Finally, the selective influence of the environment on its fauna is discussed and, conversely, the influence of regulation, a synthesis of these interrelations. Morphological adaptations of the animals inhabiting various types of terrestrial environments are considered in relation to locomotion, feeding, and escape from enemies. Physiological adaptations are also mentioned briefly, and the adaptative importunate of diurnal and seasonal rhythms is stressed.
This book will provide the state-of-the-art on most of the topics involved in the ecology and conservation of birds of prey. With chapters authored by the most recognized and prestigious researchers on each of the fields, this book will become an authorized reference volume for raptor biologists and researchers around the world.
This book offers a concise but comprehensive introduction to desert ecology and adopts a strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis in the book is on the organisms that dominate this harsh environment, although theoretical and experimental aspects are also discussed. In this updated second edition, there is a greater focus on the effects of climate change and some of its likely effects on deserts, seeing desertification as among the most serious results of climate change, leading ultimately to the increasing size of arid and semi-arid regions. The Biology of Deserts Second Edition includes a wide range of ecological and evolutionary issues including morphological and physiological adaptations of desert plants and animals, species interactions, the importance of predation and parasitism, food webs, biodiversity, and conservation. It features a balance of plant and animal (both invertebrate and vertebrate) examples, and also emphasizes topical applied issues such as desertification and invasive species. The book concludes by considering the positive aspects of desert conservation. This accessible textbook is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers working in the field of desert ecology.
Playback is the technique of rebroadcasting natural or synthetic signals to animals and observing their response. The ability to present a putative signal in isolation, without the potential confounding effects of other activities of the signaller, is the main reason for the depth and range of our knowledge of communication systems. To date, playback of sound signals has predominated, but playback of electric signals and even video playback of visual signals suggests that playback will become just as prevalent in studies of communication in other sensory modalities. This book is one of the outcomes of a workshop on playback held at Thombridge Hall in the Peak District National Park, England during August 1991. There were two reasons for organising the workshop. First, the considerable and lively debate in the literature about the design and analysis of playback experiments -the pseudoreplication debate -was in danger of generating more heat than light. A workshop forum seemed the obvious place to clarify and, if possible, resolve the debate. Second, with the number of new playback and analysis techniques increasing rapidly, it seemed an opportune moment to discuss these techniques and to review some rapidly developing areas of interest in sound communication.
This book focuses on the use of molecular tools to study small populations of rare and endangered mammals, and presents case studies that apply an evolutionary framework to address innovative questions in the emerging field of mammalian conservation genomics using a highly diverse set of novel molecular tools. Novel and more precise molecular technologies now allow experts in the field of mammology to interpret data in a more contextual and empirical fashion and to better describe the evolutionary and ecological processes that are responsible for the patterns they observe. The book also demonstrates how recent advances in genetic/genomic technologies have been applied to assess the impact of environmental/anthropogenic changes on the health of small populations of mammals. It examines a range of issues in the field of mammalian conservation genomics, such as the role that the genetic diversity of the immune system plays in disease protection and local adaptation; the use of noninvasive techniques and genomic banks as a resource for monitoring and restoring populations; the structuring of population by physical barriers; and genetic diversity. Further, by integrating research from a variety of areas - including population genetics, molecular ecology, systematics, and evolutionary and conservation biology - it enables readers to gain a deeper understanding of the conservation biology of mammals that are at increasing risk of extinction at local, regional and global scales. As such, it offers a unique resource for a broad readership interested in the conservation biology of mammals and conservation management strategies to better preserve biodiversity.
This book discusses oxidative stress and hormesis from the perspective of an evolutionary ecologist or physiologist. In the first of ten chapters, general historical information, definitions, and background of research on oxidative stress physiology, hormesis, and life history are provided. Chapters 2-10 highlight the different solutions that organisms have evolved to cope with the oxidative threats posed by their environments and lifestyles. The author illustrates how oxidative stress and hormesis have shaped diversity in organism life-histories, behavioral profiles, morphological phenotypes, and aging mechanisms. The book offers fascinating insights into how organisms work and how they evolve to sustain their physiological functions under a vast array of environmental conditions.
1. First book to adapt and explain health promotion, harm reduction and health equity issues in a One Health context and in terms of animal health. 2. Action oriented, focusing on principles and lessons learned in case studies to demonstrate how to inspire actions to protect the shared health of people, animals and environments. 3. Emphasizes what we can do to keep things healthy, thus addressing the growing calls to shift from a reactive to proactive approach in One Health. 4. Examines One Health in terms of the wider threats to the world, like climate change, thus expanding its scope of practice and helping find common ground between many emerging fields that are trying to co-manage human-animal and environmental health.
Biology of Termites, a Modern Synthesis brings together the major advances in termite biology, phylogenetics, social evolution and biogeography. In this new volume, David Bignell, Yves Roisin and Nathan Lo have brought together leading experts on termite taxonomy, behaviour, genetics, caste differentiation, physiology, microbiology, mound architecture, biogeography and control. Very strong evolutionary and developmental themes run through the individual chapters, fed by new data streams from molecular sequencing, and for the first time it is possible to compare the social organisation of termites with that of the social Hymenoptera, focusing on caste determination, population genetics, cooperative behaviour, nest hygiene and symbioses with microorganisms. New chapters have been added on termite pheromones, termites as pests of agriculture and on destructive invasive species.
This book provides new insights into the social behavior of bats - one of the most fascinating topics currently being pursued by researchers. After an introduction reviewing the history of research in bat behavioral ecology, it covers three major themes: bat sociality per se (Part I), bat communication (Part II), and ecological aspects (Part III). Part I offers a concise overview of the social organization and systems of bats, introducing readers to the complexity and dynamics of group structures. Part II is devoted to the innovative field of social communication, focusing on bat songs, dialects and calls. Part III discusses the influence of the environment on bat behavior, particularly with regard to roosting and foraging. This book addresses the needs of researchers working in behavioral sciences, evolution and ecology.
The contributed volume puts emphasis on a superior role of water in (bio)systems exposed to a mechanical stimulus. It is well known that water plays an extraordinary role in our life. It feeds mammalian or other organism after distributing over its whole volume to support certain physiological and locomotive (friction-adhesion) processes to mention but two of them, both of extreme relevance. Water content, not only in the mammalian organism but also in other biosystems such as whether those of soil which is equipped with microbiome or the ones pertinent to plants, having their own natural network of water vessels, is always subjected to a force field.The decisive force field applied to the biosystems makes them biomechanically agitated irrespective of whether they are subjected to external or internal force-field conditions. It ought to be noted that the decisive mechanical factor shows up in a close relation with the space-and-time scale in which it is causing certain specific phenomena to occur.The scale problem, emphasizing the range of action of gravitational force, thus the millimeter or bigger force vs. distance scale, is supposed to enter the so-called macroscale approach to water transportation through soil or plants' roots system. It is merely related to a percolation problem, which assumes to properly inspect the random network architecture assigned to the biosystems invoked. The capillarity conditions turn out to be of prior importance, and the porous-medium effect has to be treated, and solved in a fairly approximate way.The deeper the scale is penetrated by a force-exerting and hydrated agent the more non-gravitational force fields manifest. This can be envisaged in terms of the corresponding thermodynamic (non-Newtonian) forces, and the phenomena of interest are mostly attributed to suitable changes of the osmotic pressure. In low Reynolds number conditions, thus in the (sub)micrometer distance-scale zone, they are related with the corresponding viscosity changes of the aqueous, e.g. cytoplasmatic solutions, of semi-diluted and concentrated (but also electrolytic) characteristics. For example, they can be observed in articulating systems of mammals, in their skin, and to some extent, in other living beings, such as lizards, geckos or even insects. Through their articulating devices an external mechanical stimulus is transmitted from macro- to nanoscale, wherein the corresponding osmotic-pressure conditions apply. The content of the proposed work can be distributed twofold. First, the biomechanical mammalian-type (or, similar) systems with extraordinary relevance of water for their functioning will be presented, also including a presentation of water itself as a key physicochemical system/medium. Second, the suitably chosen related systems, mainly of soil and plant addressing provenience, will be examined thoroughly. As a common denominator of all of them, it is proposed to look at their hydrophobic and/or (de)hydration effects, and how do they impact on their basic mechanical (and related, such as chemo-mechanical or piezoelectric, etc.) properties. An additional tacit assumption employed throughout the monograph concerns statistical scalability of the presented biosystems which is equivalent to take for granted a certain similarity between local and global system's properties, mostly those of mechanical nature. The presented work's chapters also focus on biodiversity and ecological aspects in the world of animals and plants, and the related systems. The chapters' contents underscore the bioinspiration as the key landmark of the proposed monograph.
This book aims at providing students and researchers an advanced integrative overview on zooplankton ecology, covering marine and freshwater organisms, from microscopic phagotrophic protists, to macro-jellyfishes and active fish larvae. The first book section addresses zooplanktonic organisms and processes, the second section is devoted to zooplankton spatial and temporal distribution patterns and trophic dynamics, and the final section is dedicated to emergent methodological approaches (e.g., omics). Book chapters include comprehensive synthesis, observational and manipulative studies, and sediment-based analysis, a vibrant imprint of benthic-pelagic coupling and ecosystem connectivity. Most chapters also address the impacts of anticipated environmental changes (e.g., warming, acidification).
This book offers a new explanation for the development of flight in mammals and offers detailed morphological descriptions of mammals with flapping flight. The skeletomuscular apparatus of the shoulder girdle and forelimbs of tree shrews, flying lemurs and bats is described in detail. Special attention is paid to the recognition of peculiar features of the skeleton and joints. For the basic locomotor patterns of flying lemurs and bats, the kinematic models of the shoulder girdle elements are developed. The most important locomotor postures of these animals are analyzed by means of statics. The key structural characters of the shoulder girdle and forelimbs of flying lemurs and bats, the formation of which provided transition of mammals from terrestrial locomotion to gliding and then, to flapping flight, are recognized. The concept is proposed that preadaptations preceding the acquisition of flapping flight could have come from widely sprawled forelimb posture while gliding from tree to tree and running up the thick trunks. It is shown that flying lemur is an adequate morphofunctional model for an ancestral stage of bats. The evolutionary ecomorphological scenario describing probable transformational stages of typical parasagittal limbs of chiropteran ancestors into wings is developed.
Islands are special because they promote unique forms of life, and large proportions of the species they hold are found nowhere else on Earth. The mammals of the South-west Pacific are no exception, with many distributed only across single islands or archipelagos. Mammals of the South-west Pacific details the natural history for more than 180 species of marsupials, bats and rodents from 24 Pacific nations and territories. Species profiles are accompanied by distribution maps, illustrations and photographs – many being the first images ever captured for the species. By combining available knowledge with unpublished data collected over years of field work, Mammals of the South-west Pacific forms a definitive guide to the mammals from this region.
A heartfelt hymn to the sea and an unforgettable introduction to one of the most gifted nature writers of the new generation The seas cover over two thirds of our planet and yet most of us live our lives on land, creatures of a different element, at once fascinated and terrified by the beauty and power of these great bodies of water. There are some, though, who go to sea, who get to know its many moods -- the tranquil and mirror-like, the raging and ripple-swept -- and who bring back with them their stories of wonder and warning. Hannah Stowe is one such sea-goer and one such storyteller. Drawing on her expertise as a marine biologist and sailor, and her experiences in the North Sea, the North Atlantic, the Mediterranean, the North Sea, the Celtic Sea, and the Caribbean, Move Like Water is an exploration of the human relationship with the sea, the powerful impression it has made on our culture, and the terrible damage we have inflicted upon its ecosystems. In shimmering, fluid prose, Stowe introduces us to five keystone marine creatures - the sperm whale, the humpback whale, the orca, the albatross and the firecrow - encouraging us to fall in love with the seas as she has, to appreciate their majesty and their vulnerability. |
