This is a tale of human obsession, one intrepid tuna, the dedicated fisherman who caught and set her free, the promises and limits of ocean science and the big truth of how our insatiable appetite for bluefin transformed a cottage industry into a global dilemma. In 2004, an enigmatic charter captain named Al Anderson caught and marked one Atlantic bluefin tuna off New England’s coast with a plastic fish tag. Fourteen years later that fish – dubbed Amelia for her ocean-spanning journeys – died in a Mediterranean fish trap, sparking Karen Pinchin’s riveting investigation into the marvels, struggles, and prehistoric legacy of this remarkable species. Over his fishing career Al marked more than sixty thousand fish with plastic tags, an obsession that made him nearly as many enemies as it did friends. His quest landed him in the crossfire of an ongoing fight between a booming bluefin tuna industry and desperate conservation efforts, a conflict that is once again heating up as overfishing and climate change threaten the fish’s fate. Kings of Their Own Ocean is an urgent investigation that combines science, business, crime, and environmental justice. As Pinchin writes, ‘as a global community, we are collectively only ever a few terrible choices away from wiping out any ocean species.’ Through her exclusive access and interdisciplinary, mesmerizing lens, readers will join her on boats and docks as she visits tuna hot spots and scientists from Portugal to Japan, New Jersey to Nova Scotia, and glimpse, as the author does, rays of dazzling hope for the future of our oceans.
The immune systems of human and non-human primates have diverged over time, such that some species differ considerably in their susceptibility, symptoms, and survival of particular infectious diseases. Variation in primate immunity is such that major human pathogens - such as immunodeficiency viruses, herpesviruses and malaria-inducing species of"Plasmodium"- elicit striking differences in immune response between closely related species and within primate populations. These differences in immunity are the outcome of complex evolutionary processes that include interactions between the host, its pathogens and symbiont/commensal organisms. The success of some pathogens in establishing persistent infections inhumans and other primateshas been determined not just by the molecular evolution of the pathogen and its interactions with the host, but also by the evolution of primate behavior and ecology, microflora, immune factors and the evolution of other biological systems. To explore how interactions between primates and their pathogenshave shaped their mutual molecular evolution, "Primates, Pathogens and Evolution"brings together research that explorescomparativeprimate immune function, the emergence of major and neglected primatediseases, primate-microorganism molecular interactions, and related topics. Thisbookwill be of interest to anyone curious as to why infectious diseases manifest differently in humans and their closest relatives. It will be of particular interest to scholars specializing in humanand non-human primate evolution, epidemiology and immunology, and disease ecology."Primates, Pathogens and Evolution"offers anoverview and discussion of current findings on differences in the molecular mechanics of primate immune response, as well as on pathogen-mediated primate evolution and human and non-human primate health."
The regenerating vertebrate limb is an excellent model for exploring a number of significant questions in developmental biology. Written by leading investigators in the field, this collection provides a comprehensive discussion of the roles played by the major regulators affecting limb regeneration and repair following trauma. Using the amphibian limb as the recognized model system, the contributors explore in detail the contributions made by biopotentials, the skin, the endocrine system, and nerves in regulating such events as dedifferentiation, the proliferation of blastema cells, and pattern formation. The modulating roles of blood cells and the immune system are re-examined, and the exciting studies on the isolation and characterization of neurotropic factors reviewed. The sometimes provocative but always informative and up-to-date discussions provided in this volume will be of particular interest to developmental biologists, anatomists, neuroscientists, and cell biologists.

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.
The basic goal of the volume is to compile the most up to date research on how high altitude affects the behavior, ecology, evolution and conservation status of primates, especially in comparison to lowland populations. Historically, the majority of primate studies have focused on lowland populations. However, as the lowlands have been disappearing, more and more primatologists have begun studying populations located in higher altitudes. High altitude populations are important not only because of their uniqueness, but also because they highlight the range of primate adaptability and the complex variables that are involved in primate evolution. These populations are good examples of how geographic scales result in diversification and/or speciation. Yet, there have been very few papers addressing how this high altitude environment affects the behavior, ecology, and conservation status of these primates. "
This is the ninth volume of ten in the The Natural History of the Crustacea Series. The chapters in this volume synthesize the diverse topics in fisheries and aquaculture. In the first part of the book, chapters explore worldwide crustacean fisheries. This section comes to a conclusion with two chapters on harvested crustaceans that are usually not within the focus of the mainstream fisheries research, possibly because they are caught by local fishing communities in small-scale operations and sold locally as subsistence activity. In the second part of the book, the authors explore the variety of cultured crustacean species, like shrimps, prawns, lobsters, and crabs. Chapters in the third part of the volume focus on important challenges and opportunities, including diseases and parasitism, the use of crustacean as bioindicators, and their role in biotechnology.
This comprehensive volume, which brings together outstanding investigators of cutaneous epidermal differentiation, contributes to a general appreciation of the modulation of gene action and provides valuable insights into the causes of certain cutaneous pathologies that involve abnormal epidermal differentiation.

Provides an up-to-date account of evolution of vertebrates Includes numerous beautiful color reconstructions of prehistoric vertebrates Describes extinct vertebrates and their evolutionary history Discusses and illustrates the first vertebrates, as well as familiar lineages of fishes, amphibians, reptiles, birds, and mammals Reviews mass extinctions and other important events in the diversification of vertebrates
A multitude of direct and indirect human influences have significantly altered the environmental conditions, composition, and diversity of marine communities. However, understanding and predicting the combined impacts of single and multiple stressors is particularly challenging because observed ecological feedbacks are underpinned by a number of physiological and behavioural responses that reflect stressor type, severity, and timing. Furthermore, integration between the traditional domains of physiology and ecology tends to be fragmented and focused towards the effects of a specific stressor or set of circumstances. This novel volume summarises the latest research in the physiological and ecological responses of marine species to a comprehensive range of marine stressors, including chemical and noise pollution, ocean acidification, hypoxia, UV radiation, thermal and salinity stress before providing a perspective on future outcomes for some of the most pressing environmental issues facing society today. Stressors in the Marine Environment synthesises the combined expertise of a range of international researchers, providing a truly interdisciplinary and accessible summary of the field. It is essential reading for graduate students as well as professional researchers in environmental physiology, ecology, marine biology, conservation biology, and marine resource management. It will also be of particular relevance and use to the regulatory agencies and authorities tasked with managing the marine environment, including social scientists and environmental economists.

It addition, it provides information on good aquaculture practices and how to scientifically manage aquaculture and fishery sectors.
Elephants are a keystone species and have been a part of the magic of the thickly forested land of South Africa for millennia. This book focuses on the history and work of Knysna Elephant Park, a leading South African elephant research facility that has been home to more than 40 elephants in 25 years. Unfortunately, all the mystique of the Knysna elephant has been reduced to a single elephant left alive. Exploring a wide range of topics, this book covers the impact of elephants' interactions with tourists, how they recover from trauma and even their relevance in human healthcare. Renowned elephant researchers explain the majesty of the elephant brain, which has the largest temporal lobe devoted to communication, language, spatial memory and cognition. To this effect, the book emphasizes the threat of poaching to these gentle giants, which has almost forced them to extinction. Perhaps if humans pay attention to how elephants symbolize our relationship with nature, we can learn important lessons about humanity itself.
Nonhuman primates have played critical roles in biomedical research, and they are among the few animals whose use in research continues to increase. The scienti?c value of nonhuman primates derives from their close phylogenetic proximity to man and their consequent anatomic, physiologic, and genetic similarities to man. Only nonhuman primates can provide adequate models for many complex physiological and disease processes of humans. The baboon is a relative newcomer to the repertoire of nonhuman primates used in biomedical research. However, in less than 50 years since its ?rst use in the U. S. , it has become one of the most popular laboratory primate species. It is larger than the other widely used monkey species, making it advantageous for many types of experiments and technological developments. It is extraordinarily hardy and highly fecund in captivity. It closely resembles humans in a variety of physiological and disease processes, such as cholesterol metabolism, early stages of atherosclerosis, and alcoholic liver disease. Its chromosomes closely resemble those of humans, and many genes of the two species lie in the same chromosomal order. Among all primates, baboons are the most widely used models for the genetics of susceptibility to complex diseases and they are the ?rst nonhuman primate for which a framework genetic linkage map was established. In addition, the baboon genome is currently being sequenced, and as a result the utility of this species for biomedical research will be dramatically increased.
The basic goal of the volume is to compile the most up to date research on the effect of ecotourism on Indonesia's primates. The tremendous diversity of primates in Indonesia, in conjunction with the conservation issues facing the primates of this region, have created a crisis whereby many of Indonesia's primates are threatened with extinction. Conservationists have developed the concept of "sustainable ecotourism" to fund conservation activities. National parks agencies worldwide receive as much as 84% of their funding from ecotourism. While ecotourism funds the majority of conservation activities, there have been very few studies that explore the effects of ecotourism on the habitat and species that they are designed to protect. It is the burgeoning use of "ecotourism" throughout Indonesia that has created a need for this volume where the successes and pitfalls at various sites can be identified and compared.
Denis Noble Nearly a decade after completion of the first draft of the entire Human Genome sequence we are in a better position to assess the nature and the consequences of that heroic achievement, which can be seen as the culmination of the molecular biological revolution of the second half of the twentieth century. The achievement itself was celebrated at the highest levels (President and Prime Minister) on both sides of the Atlantic, and rightly so. DNA sequencing has become sufficiently c- mon now, even to the extent of being used in law courts, that it is easy to forget how technically difficult it was and how cleverly the sequencing teams solved those problems in the exciting race to finish by the turn of the century [1, 2]. The fanfares were misplaced, however, in an important respect. The metaphors used to describe the project and its biological significance gave the impression to the public at large, and to many scientists themselves, that this sequence would reveal the secrets of life. DNA had already been likened to a computer program [3]. The "genetic program" for life was therefore to be found in those sequences: A kind of map that had simply to be unfolded during development. The even more colo- ful "book of life" metaphor gave the promise that reading that book would lead to a veritable outpouring of new cures for diseases, hundreds of new drug targets, and a brave new world of medicine.
This book summarizes the key adaptations enabling extremophile fishes to survive under harsh environmental conditions. It reviews the most recent research on acidic, Antarctic, cave, desert, hypersaline, hypoxic, temporary, and fast-flowing habitats, as well as naturally and anthropogenically toxic waters, while pointing out generalities that are evident across different study systems. Knowledge of the different adaptations that allow fish to cope with stressful environmental conditions furthers our understanding of basic physiological, ecological, and evolutionary principles. In several cases, evidence is provided for how the adaptation to extreme environments promotes the emergence of new species. Furthermore, a link is made to conservation biology, and how human activities have exacerbated existing extreme environments and created new ones. The book concludes with a discussion of major open questions in our understanding of the ecology and evolution of life in extreme environments. |
