Protist Diversity and Geographical Distribution by W. Foissner,David Leslie Hawksworth Pdf

Conservation and biodiversity of protists The conservation of biodiversity is not just an issue of plants and vertebrates. It is the scarcely visible invertebrates and myriads of other microscopic organisms that are crucial to the maintenance of ecological processes on which all larger organisms and the composition of the atmosphere ultimately depend. Biodiversity and Conservation endeavours to take an holistic view of biodiversity, and when the opportunity arises to issue collections of papers dealing with too-often neglected groups of organisms. The protists, essentially eukaryotes that cannot be classi?ed in the kingdoms of animals, fungi, or plants, include some of the lea- known groups of organisms on earth. They are generally treated as a separate kingdom, commonly named Protista (or Protoctista) in textbooks, but in reality they are a mixture of organisms with disparate a?nities. Some authors have hypothesized that the numbers of protists are not especially large, and that many have extraordinarily wide distributions. However, the p- ture that unfolds from the latest studies discussed in this issue is di?erent. There are many species with wide ranges, and proportionately more cosmopolitan species than in macroorganism groups, as a result of their long evolutionary histories, but there are also de?nite patterns and geographical restrictions to be found. Further, some protists are linked to host organisms as mutualists or parasites and necessarily con?ned to the distributions of their hosts.

Marine Protists by Susumu Ohtsuka,Toshinobu Suzaki,Takeo Horiguchi,Noritoshi Suzuki,Fabrice Not Pdf

This comprehensive book provides a unique overview of advances in the biology and ecology of marine protists. Nowadays marine protistology is a hot spot in science to disclose life phenomena using the latest techniques. Although many protistological textbooks deal with the cytology, genetics, ecology, and pathology of specific organisms, none keeps up with the quick pace of new discoveries on the diversity and dynamics of marine protists in general. The bookMarine Protists: Diversity and Dynamics gives an overview of current research on the phylogeny, cytology, genomics, biology, ecology, fisheries, applied sciences, geology and pathology of marine free-living and symbiotic protists. Poorly known but ecologically important protists such as labyrinthulids and apostome ciliates are also presented in detail. Special attention is paid to complex interactions between marine protists and other organisms including human beings. An understanding of the ecological roles of marine protists is essential for conservation of nature and human welfare. This book will be of great interest not only to scientists and students but also to a larger audience, to give a better understanding of protists’ diverse roles in marine ecosystems.

Soil Protists by Stefan Geisen Pdf

Protists are by far the most diverse and abundant eukaryotes in soils. Nevertheless, very little is known about individual representatives, the diversity and community composition and ecological functioning of these important organisms. For instance, soil protists are commonly lumped into a single functional unit, i.e. bacterivores. This work tackles missing knowledge gaps on soil protists and common misconceptions using multi-methodological approaches including cultivation, microcosm experiments and environmental sequencing. In a first part, several new species and genera of amoeboid protists are described showing their immense unknown diversity. In the second part, the enormous complexity of soil protists communities is highlighted using cultivation- and sequence-based approaches. In the third part, the present of diverse mycophagous and nematophagous protists are shown in functional studies on cultivated taxa and their environmental importance supported by sequence-based approaches. This work is just a start for a promising future of soil Protistology that is likely to find other important roles of these diverse organisms.

Biogeography of Microscopic Organisms by Diego Fontaneto Pdf

Bringing together the viewpoints of leading experts in taxonomy, ecology and biogeography of different taxa, this book synthesises discussion surrounding the so-called 'everything is everywhere' hypothesis. It addresses the processes that generate spatial patterns of diversity and biogeography in organisms that can potentially be cosmopolitan. The contributors discuss questions such as: are microorganisms (e.g. prokaryotes, protists, algae, yeast and microscopic fungi, plants and animals) really cosmopolitan in their distribution? What are the biological properties that allow such potential distribution? Are there processes that would limit their distribution? Are microorganisms intrinsically different from macroscopic ones? What can microorganisms tell us about the generalities of biogeography? Can they be used for experimental biogeography? Written for graduate students and academic researchers, the book promotes a more complete understanding of the spatial patterns and the general processes in biogeography.

Nature and Human Society by Peter H. Raven Pdf

From earliest times, human beings have noticed patterns in nature: night and day, tides and lunar cycles, the changing seasons, plant succession, and animal migration. While recognizing patterns conferred great survival advantage, we are now in danger from our own success in multiplying our numbers and altering those patterns for our own purposes. It is imperative that we engage again with the patterns of nature, but this time, with awareness of our impact as a species. How will burgeoning human populations affect the health of ecosystems? Is loss of species simply a regrettable byproduct of human expansion? Or is the planet passing into a new epoch in just a few human generations? Nature and Human Society presents a wide-ranging exploration of these and other fundamental questions about our relationship with the environment. This book features findings, insights, and informed speculations from key figures in the field: E.O. Wilson, Thomas Lovejoy, Peter H. Raven, Gretchen Daily, David Suzuki, Norman Myers, Paul Erlich, Michael Bean, and many others. This volume explores the accelerated extinction of species and what we stand to lose--medicines, energy sources, crop pollination and pest control, the ability of water and soil to renew itself through biological processes, aesthetic and recreational benefits--and how these losses may be felt locally and acutely. What are the specific threats to biodiversity? The book explores human population growth, the homogenization of biota as a result in tourism and trade, and other factors, including the social influences of law, religious belief, and public education. Do we have the tools to protect biodiversity? The book looks at molecular genetics, satellite data, tools borrowed from medicine, and other scientific techniques to firm up our grasp of important processes in biology and earth science, including the "new" science of conservation biology. Nature and Human Society helps us renew our understanding and appreciation for natural patterns, with surprising details about microorganisms, nematodes, and other overlooked forms of life: their numbers, pervasiveness, and importance to the health of the soil, water, and air and to a host of human endeavors. This book will be of value to anyone who believes that the world's gross natural product is as important as the world's gross national product.

Concepts of Biology by Samantha Fowler,Rebecca Roush,James Wise Pdf

Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

The Biological Resources of Model Organisms by Robert L. Jarret,Kevin McCluskey Pdf

This book discusses 14 model organisms and are used by thousands of researchers, teachers, and students each year in laboratories and classrooms, around the globe. Though acknowledged in innumerable scientific journal articles, little is generally known about the origin of these collections, how the organisms contained within them have been acquired, and how they are maintained and distributed. While some collections such as Drosophila have long histories others, such as the collection of Brachionus, are relatively new. They vary greatly in size. Yet, all have contributed and are continuing to contribute to global research efforts in many areas of scientific research as diverse as tissue regeneration, skin cancer, evolution, water purity, gene function, and hundreds of others. In addition to providing the raw materials for national and international research programs, these collections also provide educational tools used by colleges and high schools. The chapters in this book attempt to provide a brief look at the individual organisms, how they came to be accepted as model organisms, the history of the individual collections, examples of how the organisms have been and are being used in scientific research, and a description of the facilities and procedures used to maintain them. Features: • Provides an in-depth look at the collections of 14 model organisms that have enabled innumerable scientific breakthroughs over decades, and that continue to do so. • Includes detailed descriptions of the operating procedures used for the maintenance of each model organism collection. • Discusses the holdings of the collections of model organisms and its relevance to past, current and future scientific research. • Written by the leaders in the field of the management of model organisms.
