| anatomy of a tardigrade: Water Bears: The Biology of Tardigrades Ralph O. Schill, 2019-02-14 Offering extensive information on tardigrades, this volume begins with a chapter on the history of tardigrades, from the first description by Goeze in 1773, until 1929, when the most comprehensive monographic approach by E. Marcus was published. Tardigrades’ organ systems, including their integument, body cavity, digestive, muscular, nervous and reproductive systems, as well as their overall external morphology, are summarized in the second chapter. Subsequent chapters present the current state of knowledge on tardigrade phylogeny, biogeography, paleontology, cytology and cytogenetics. In addition, the book provides insights into the ecology of tardigrades in marine, freshwater and terrestrial habitats. The reproduction, development and life cycles are summarized and the extraordinary environmental adaptations of encystment and cyclomorphosis, desiccation tolerance, freezing tolerance and radiation tolerance are discussed in detail. Further chapters provide an overview of key approaches in molecular tardigrade studies and describe techniques for sampling and sample processing. The book closes with a list of tardigrade taxa up to a sub-generic level, including the type species of each genus, the numbers of lower taxa in each taxon, and the main environments in which the taxa were found. Given its depth of coverage, the volume offers an invaluable resource for scientists from various disciplines who plan to research tardigrades, and for all others who are interested in these fascinating animals. |
| anatomy of a tardigrade: The Biology of Tardigrades Ian M. Kinchin, 1994 The Biology of Tardigrades is the only modern comprehensive account of marine and freshwater tardigrades. It contains the first taxonomic review for over a decade in addition to covering every aspect of their biology. |
| anatomy of a tardigrade: Evo-Devo: Non-model Species in Cell and Developmental Biology Waclaw Tworzydlo, Szczepan M. Bilinski, 2019-10-09 Evolutionary developmental biology or evo-devo is a field of biological research that compares the underlying mechanisms of developmental processes in different organisms to infer the ancestral condition of these processes and elucidate how they have evolved. It addresses questions about the developmental bases of evolutionary changes and evolution of developmental processes. The book’s content is divided into three parts, the first of which discusses the theoretical background of evo-devo. The second part highlights new and emerging model organisms in the evo-devo field, while the third and last part explores the evo-devo approach in a broad comparative context. To the best of our knowledge, no other book combines these three evo-devo aspects: theoretical considerations, a comprehensive list of emerging model species, and comparative analyses of developmental processes. Given its scope, the book will offer readers a new perspective on the natural diversity of processes at work in cells and during the development of various animal groups, and expand the horizons of seasoned and young researchers alike. |
| anatomy of a tardigrade: Anatomy of Dolphins Bruno Cozzi, Stefan Huggenberger, Helmut A Oelschläger, 2016-09-21 The Anatomy of Dolphins: Insights into Body Structure and Function is a precise, detailed, fully illustrated, descriptive, and functionally oriented text on the anatomy and morphology of dolphins.

| anatomy of a tardigrade: Structure and Evolution of Invertebrate Nervous Systems Andreas Schmidt-Rhaesa, Steffen Harzsch, Günter Purschke, 2015-12-17 The nervous system is particularly fascinating for many biologists because it controls animal characteristics such as movement, behavior, and coordinated thinking. Invertebrate neurobiology has traditionally been studied in specific model organisms, whilst knowledge of the broad diversity of nervous system architecture and its evolution among metazoan animals has received less attention. This is the first major reference work in the field for 50 years, bringing together many leading evolutionary neurobiologists to review the most recent research on the structure of invertebrate nervous systems and provide a comprehensive and authoritative overview for a new generation of researchers. Presented in full colour throughout, Structure and Evolution of Invertebrate Nervous Systems synthesizes and illustrates the numerous new findings that have been made possible with light and electron microscopy. These include the recent introduction of new molecular and optical techniques such as immunohistochemical staining of neuron-specific antigens and fluorescence in-situ-hybridization, combined with visualization by confocal laser scanning microscopy. New approaches to analysing the structure of the nervous system are also included such as micro-computational tomography, cryo-soft X-ray tomography, and various 3-D visualization techniques. The book follows a systematic and phylogenetic structure, covering a broad range of taxa, interspersed with chapters focusing on selected topics in nervous system functioning which are presented as research highlights and perspectives. This comprehensive reference work will be an essential companion for graduate students and researchers alike in the fields of metazoan neurobiology, morphology, zoology, phylogeny and evolution. |
| anatomy of a tardigrade: Arthropod Relationships Richard A. Fortey, Richard H. Thomas, 2012-12-06 The arthropods contain more species than any other animal group, but the evolutionary pathways which led to their current diversity are still an issue of controversy. Arthropod Relationships provides an overview of our current understanding, responding to the new data arising from sequencing DNA, the discovery of new Cambrian fossils as direct evidence of early arthropod history, and developmental genetics. These new areas of research have stimulated a reconsideration of classical morphology and embryology. Arthropod Relationships is the first synthesis of the current debate to emerge: not since the volume edited by Gupta was published in 1979 has the arthropod phylogeny debate been, considered in this depth and breadth. Leaders in the various branches of arthropod biology have contributed to this volume. Chapters focus progressively from the general issues to the specific problems involving particular groups, and thence to a consideration of embryology and genetics. This wide range of disciplines is drawn on to approach an understanding of arthropod relationships, and to provide the most timely account of arthropod phylogeny. This book should be read by evolutionary biologists, palaeontologists, developmental geneticists and invertebrate zoologists. It will have a special interest for post-graduate students working in these fields. |
| anatomy of a tardigrade: Statistical Methods in Molecular Evolution Rasmus Nielsen, 2006-05-06 In the field of molecular evolution, inferences about past evolutionary events are made using molecular data from currently living species. With the availability of genomic data from multiple related species, molecular evolution has become one of the most active and fastest growing fields of study in genomics and bioinformatics. Most studies in molecular evolution rely heavily on statistical procedures based on stochastic process modelling and advanced computational methods including high-dimensional numerical optimization and Markov Chain Monte Carlo. This book provides an overview of the statistical theory and methods used in studies of molecular evolution. It includes an introductory section suitable for readers that are new to the field, a section discussing practical methods for data analysis, and more specialized sections discussing specific models and addressing statistical issues relating to estimation and model choice. The chapters are written by the leaders of field and they will take the reader from basic introductory material to the state-of-the-art statistical methods. This book is suitable for statisticians seeking to learn more about applications in molecular evolution and molecular evolutionary biologists with an interest in learning more about the theory behind the statistical methods applied in the field. The chapters of the book assume no advanced mathematical skills beyond basic calculus, although familiarity with basic probability theory will help the reader. Most relevant statistical concepts are introduced in the book in the context of their application in molecular evolution, and the book should be accessible for most biology graduate students with an interest in quantitative methods and theory. Rasmus Nielsen received his Ph.D. form the University of California at Berkeley in 1998 and after a postdoc at Harvard University, he assumed a faculty position in Statistical Genomics at Cornell University. He is currently an Ole Rømer Fellow at the University of Copenhagen and holds a Sloan Research Fellowship. His is an associate editor of the Journal of Molecular Evolution and has published more than fifty original papers in peer-reviewed journals on the topic of this book. From the reviews: ...Overall this is a very useful book in an area of increasing importance. Journal of the Royal Statistical Society I find Statistical Methods in Molecular Evolution very interesting and useful. It delves into problems that were considered very difficult just several years ago...the book is likely to stimulate the interest of statisticians that are unaware of this exciting field of applications. It is my hope that it will also help the 'wet lab' molecular evolutionist to better understand mathematical and statistical methods. Marek Kimmel for the Journal of the American Statistical Association, September 2006 Who should read this book? We suggest that anyone who deals with molecular data (who does not?) and anyone who asks evolutionary questions (who should not?) ought to consult the relevant chapters in this book. Dan Graur and Dror Berel for Biometrics, September 2006 Coalescence theory facilitates the merger of population genetics theory with phylogenetic approaches, but still, there are mostly two camps: phylogeneticists and population geneticists. Only a few people are moving freely between them. Rasmus Nielsen is certainly one of these researchers, and his work so far has merged many population genetic and phylogenetic aspects of biological research under the umbrella of molecular evolution. Although Nielsen did not contribute a chapter to his book, his work permeates all its chapters. This book gives an overview of his interests and current achievements in molecular evolution. In short, this book should be on your bookshelf. Peter Beerli for Evolution, 60(2), 2006 |

| anatomy of a tardigrade: The Book of Eggs Mark E. Hauber, 2014-08-01 From the brilliantly green and glossy eggs of the Elegant Crested Tinamou—said to be among the most beautiful in the world—to the small brown eggs of the house sparrow that makes its nest in a lamppost and the uniformly brown or white chickens’ eggs found by the dozen in any corner grocery, birds’ eggs have inspired countless biologists, ecologists, and ornithologists, as well as artists, from John James Audubon to the contemporary photographer Rosamond Purcell. For scientists, these vibrant vessels are the source of an array of interesting topics, from the factors responsible for egg coloration to the curious practice of “brood parasitism,” in which the eggs of cuckoos mimic those of other bird species in order to be cunningly concealed among the clutches of unsuspecting foster parents. The Book of Eggs introduces readers to eggs from six hundred species—some endangered or extinct—from around the world and housed mostly at Chicago’s Field Museum of Natural History. Organized by habitat and taxonomy, the entries include newly commissioned photographs that reproduce each egg in full color and at actual size, as well as distribution maps and drawings and descriptions of the birds and their nests where the eggs are kept warm. Birds’ eggs are some of the most colorful and variable natural products in the wild, and each entry is also accompanied by a brief description that includes evolutionary explanations for the wide variety of colors and patterns, from camouflage designed to protect against predation, to thermoregulatory adaptations, to adjustments for the circumstances of a particular habitat or season. Throughout the book are fascinating facts to pique the curiosity of binocular-toting birdwatchers and budding amateurs alike. Female mallards, for instance, invest more energy to produce larger eggs when faced with the genetic windfall of an attractive mate. Some seabirds, like the cliff-dwelling guillemot, have adapted to produce long, pointed eggs, whose uneven weight distribution prevents them from rolling off rocky ledges into the sea. A visually stunning and scientifically engaging guide to six hundred of the most intriguing eggs, from the pea-sized progeny of the smallest of hummingbirds to the eggs of the largest living bird, the ostrich, which can weigh up to five pounds, The Book of Eggs offers readers a rare, up-close look at these remarkable forms of animal life. |

| anatomy of a tardigrade: The History Of Torture George Ryley Scott, 2013-10-28 First published in 2005. Torture, an enduring and seemingly not declining aspect of man's relationship to his fellow man, is an enduring thread through human history. Whether it be practiced by primitive people, the ancient Greeks or the Catholic Church, whether it be ancient China, Japan, 1930's Germany, or Northern Ireland today, torture is alarmingly systematic and consistent in its methods. Impaling, burning, rack or wheel, mutilation, drawing and quartering, burning or hanging alive in chains. A very comprehensive and readable work. |
| anatomy of a tardigrade: Marine Parasitology Klaus Rohde, 2005-09-13 This comprehensive, authoritative and up-to-date work provides the definitive overview of marine parasites worldwide. It is an invaluable reference for students and researchers in parasitology and marine biology and will also be of interest to ecologists, aquaculturists and invertebrate biologists. Initial chapters review the diversity and basic biology of the different groups of marine parasites, discussing their morphology, life cycles, infection mechanisms and effects on hosts. The ecology and importance of marine parasites are discussed in the second part of the book, where contributions investigate behavioural and ecological aspects of parasitism and discuss the evolution and zoogeography of marine parasites. In addition, the economic, environmental and medical significance of these organisms is outlined, particularly their importance in aquaculture and their effects on marine mammals and birds. Written by an international team of contributors, the emphasis is on a thorough grounding in marine parasitology combined with reviews of novel concepts and cutting-edge research. |

| anatomy of a tardigrade: At the Size Limit - Effects of Miniaturization in Insects Alexey A. Polilov, 2016-10-20 This book addresses microinsects, their structure and their differences from larger relatives. Moreover, it discusses structural changes that accompany extreme diminution in living organisms, evolutionary inventions that help insects to live in the microworld, and factors that limit the size of animals. It also takes a careful look at the potential benefits of the study of microinsects for solving biotechnological and fundamental scientific problems. Miniaturization is not only a trend in technology: it is also one of the trends in the evolution of life. Many of the problems modern engineers are still struggling with were solved by nature millions of years ago. The world of microscopic organisms, invisible to the naked eye, is all around us. Microinsects — the extremely diverse range of miniature insects less than a millimeter long — are one of the most intriguing components of this microworld. Having evolved to the size of unicellular organisms, the smallest insects managed not only to preserve their structural complexity, but also to evolve some novel features not found in larger insects. |

| anatomy of a tardigrade: Anoxia Alexander Altenbach, Joan M. Bernhard, Joseph Seckbach, 2011-10-20 ANOXIA defines the lack of free molecular oxygen in an environment. In the presence of organic matter, anaerobic prokaryotes produce compounds such as free radicals, hydrogen sulfide, or methane that are typically toxic to aerobes. The concomitance of suppressed respiration and presence of toxic substances suggests these habitats are inhospitable to Eukaryota. Ecologists sometimes term such environments 'Death Zones'. This book presents, however, a collection of remarkable adaptations to anoxia, observed in Eukaryotes such as protists, animals, plants and fungi. Case studies provide evidence for controlled beneficial use of anoxia by, for example, modification of free radicals, use of alternative electron donors for anaerobic metabolic pathways, and employment of anaerobic symbionts. The complex, interwoven existence of oxic and anoxic conditions in space and time is also highlighted as is the idea that eukaryotic inhabitation of anoxic habitats was established early in Earth history. |
| anatomy of a tardigrade: Evolution of the Insects David Grimaldi, Michael S. Engel, 2005-05-16 Insects are the most diverse group of organisms in the 3 billion-year history of life on Earth, and the most ecologically dominant animals on land. This book chronicles for the first time the complete evolutionary history of insects: their living diversity, relationships and 400 million years of fossils. Whereas other volumes have focused on either living species or fossils, this is the first comprehensive synthesis of all aspects of insect evolution. The book is illustrated with 955 photo- and electronmicrographs, drawings, diagrams, and field photos, many in full colour and virtually all of them original. The book will appeal to anyone engaged with insect diversity: professional entomologists and students, insect and fossil collectors, and naturalists. |
| anatomy of a tardigrade: Limnoperna Fortunei Demetrio Boltovskoy, 2015-04-20 This book summarizes all currently available information on the ecology, environmental impacts and control methods of the golden mussel in industrial plants. The golden mussel was introduced in Hong Kong, Taiwan, Japan, and South America between 1965 and 1990, swiftly spreading in freshwater waterbodies. In most areas invaded it has become the dominant macroinverebrate and a major fouling pest of industrial plants. Limnoperna fortunei attaches to any hard surface, as well as to some less firm substrates. The growth of Limnoperna populations in raw cooling water conduits became a common nuisance in many industrial and power plants that use raw river or lake water for their processes, both in South America and in Asia. This work is written by experts on the golden mussel from Asia, Europe, North America and South America, each chapter critically reviews previously available information, which is in sources of limited distribution, such as internal reports and theses, in various languages. |
| anatomy of a tardigrade: The Greenland Entomofauna Jens Böcher, N.P. Kristensen (†), Thomas Pape, Lars Vilhelmsen, 2015-05-26 In The Greenland Entomofauna an international team of 64 taxonomic specialists provide for the first time a richly illustrated guide to the identification of the ≈1200 species of Hexapods/Insects, Arachnids and Myriapods so far known to occur in the country. While the composition, origin and adaptations of the Greenland fauna has always been a challenge to biogeographers and ecologists/ecophysiologists, the provision of a tool for detailed identification of its constituent species is now particularly timely, since global climate change will expectedly have a particularly noticeable impact on biota at high latitudes. This obviously renders the feasibility of monitoring distributional range shifts of the principal components of this biota a matter of some urgency.

| anatomy of a tardigrade: Abominable Snowmen Ivan T. Sanderson, 2008-11-01 Scottish zoologist IVAN TERRANCE SANDERSON (1911-1973) coined the word cryptozoology and first used it in print in this hard-to-find 1961 work, the story of hairy hominids across the planet from the very beginnings of human civilization until the mid 20th century. With its scientific, anthropological approach, this is one of the first books to treat the phenomenon of Bigfoot seriously, and introduced a groundbreaking classification system for the spectrum of subhumanoids. I am happy that a whole new generation of cryptozoologists-in-training will be able to read Ivan T. Sanderson's classic book, says cryptozoologist Loren Coleman in his new introduction. This book opened the minds of many to the vastness of the hominoid reports... and spotlighted for people that Bigfoot/Sasquatch research was the next area for exploration in North America. This new edition, complete with the original illustrations and maps, is part of Cosimo's Loren Coleman Presents series. LOREN COLEMAN is author of numerous books of cryptozoology, including Bigfoot!: The True Story of Apes in America and Mothman and Other Curious Encounters. |

| anatomy of a tardigrade: Freshwater Meiofauna Simon D. Rundle, Anne L. Robertson, Jenny M. Schmid-Araya, 2002 Meiofauna are a diverse and numerous component of the fauna in freshwater ecosystems, but have been mostly ignored by freshwater scientists. Freshwater Meiofauna aims to raise the awareness of this enigmatic, microscopic component of the freshwater biota, by providing the first-ever, comprehensive review of their biology and ecology. The first section of the book gives indepth accounts of the systematics, morphological characteristics, life histories and ecological requirements of the main freshwater meiofaunal taxa (i.e. microturbellarians, rotifers, gastrotriches, nematodes, water mites, microcrustaceans and tardigrades). The second section then takes an integrated approach to review the current state-of-play in meiofaunal ecological research in freshwaters, addressing important issues, such as the importance of meiofaunal taxa in the trophic dynamics of freshwater ecosystems and the process underpinning the distribution patterns observed in meiofaunal assemblages. This book should appeal to a wide range of freshwater scientists, including novices in the study of freshwater meiobenthology and established researchers in freshwater ecology, for whom the meiofauna represent an unopened black box. Our ultimate goal is that this book will serve to promote the idea that the zoology of freshwater habitats concerns more than just fish, macroinvertebrates and microbes. |
| anatomy of a tardigrade: Dormancy and Resistance in Harsh Environments Esther Lubzens, Joan Cerda, Melody Clark, 2010-11-04 Many organisms have evolved the ability to enter into and revive from a dormant state. They can survive for long periods in this state (often even months to years), yet can become responsive again within minutes or hours. This is often, but not necessarily, associated with desiccation. Preserving one’s body and reviving it in future generations is a dream of mankind. To date, however, we have failed to learn how cells, tissues or entire organisms can be made dormant or be effectively revived at ambient temperatures. In this book studies on organisms, ranging from aquatic cyanobacteria that produce akinetes to hibernating mammals, are presented, and reveal common but also divergent physiological and molecular pathways for surviving in a dormant form or for tolerating harsh environments. Attempting to learn the functions associated with dormancy and how they are regulated is one of the great future challenges. Its relevance to the preservation of cells and tissues is one of the key concerns of this book. |
