Book excerpt: Following the trails of Hawai‘i’s snails to explore the simultaneously biological and cultural significance of extinction. In this time of extinctions, the humble snail rarely gets a mention. And yet snails are disappearing faster than any other species. In A World in a Shell, Thom van Dooren offers a collection of snail stories from Hawai‘i—once home to more than 750 species of land snails, almost two-thirds of which are now gone. Following snail trails through forests, laboratories, museums, and even a military training facility, and meeting with scientists and Native Hawaiians, van Dooren explores ongoing processes of ecological and cultural loss as they are woven through with possibilities for hope, care, mourning, and resilience. Van Dooren recounts the fascinating history of snail decline in the Hawaiian Islands: from deforestation for agriculture, timber, and more, through the nineteenth century shell collecting mania of missionary settlers, and on to the contemporary impacts of introduced predators. Along the way he asks how both snail loss and conservation efforts have been tangled up with larger processes of colonization, militarization, and globalization. These snail stories provide a potent window into ongoing global process of environmental and cultural change, including the largely unnoticed disappearance of countless snails, insects, and other less charismatic species. Ultimately, van Dooren seeks to cultivate a sense of wonder and appreciation for our damaged planet, revealing the world of possibilities and relationships that lies coiled within a snail’s shell.

Book excerpt: For the first time in years Gussie can run, climb and jump. Every breath she takes is easier now, and every step more confident, but Gussie can't help wondering about her doner. Was she young? Had she been very sick or was there an accident? And with her new life comes a whole new set of problems. She is going back to school at last - but she doesn't know anyone her own age, with the exception of Siobhan, the girl she hates most in the world. With school not meeting up to her expectations, Gussie turns to her old pastimes of bird watching and photography, but troubling news awaits her there too. And the lightning strikes and Gussie must act at once.

Download or read book Resource Selection by Animals written by B.B. Manly and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have written this book as a guide to the design and analysis of field studies of resource selection, concentrating primarily on statistical aspects of the comparison of the use and availability of resources of different types. Our in tended audience is field ecologists in general and wildlife biologists in particular who are attempting to measure the extent to which real animal populations are selective in their choice of food and habitat. As such, we have made no attempt to address those aspects of theoretical ecology that are concerned with how animals might choose their resources if they acted in an optimal manner. The book is based on the concept of a resource selection function, where this is a function of characteristics measured on resource units such that its value for a unit is proportional to the probability of that unit being used. We argue that this concept leads to a unified theory for the analysis and interpretation of data on resource selection and can replace many ad hoc statistical methods that have been used in the past.
Download or read book Selection written by Graham Bell and published by OUP Oxford. This book was released on 2008-12-18 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book adopts an experimental approach to understanding the mechanisms of evolution and the nature of evolutionary processes, with examples drawn from microbial, plant and animal systems. It incorporates insights from remarkable recent advances in theoretical modelling, and the fields of molecular genetics and environmental genomics. Adaptation is caused by selection continually winnowing the genetic variation created by mutation. In the last decade, our knowledge of how selection operates on populations in the field and in the laboratory has increased enormously, and the principal aim of this book is to provide an up-to-date account of selection as the principal agent of evolution. In the classical Fisherian model, weak selection acting on many genes of small effect over long periods of time is responsible for driving slow and gradual change. However, it is now clear that adaptation in laboratory populations often involves strong selection acting on a few genes of large effect, while in the wild selection is often strong and highly variable in space and time. Indeed these results are changing our perception of how evolutionary change takes place. This book summarizes our current understanding of the causes and consequences of selection, with an emphasis on quantitative and experimental studies. It includes the latest research into experimental evolution, natural selection in the wild, artificial selection, selfish genetic elements, selection in social contexts, sexual selection, and speciation.

Download or read book A Guide to Land Snails of Australia written by John Stanisic and published by CSIRO PUBLISHING. This book was released on 2022-07 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Australia's native land snails are an often-overlooked invertebrate group that forms a significant part of terrestrial biodiversity, with an estimated 2500 species present in Australia today. A Guide to Land Snails of Australia is an overview of Australia's native and introduced land snail faunas, offering a greater understanding of their role in the natural environment. The book presents clear diagnostic features of live snails and their shells, and is richly illustrated with a broad range of Australia's native snail, semi-slug and slug species. Comprehensive coverage is also included of the many exotic species introduced to Australia. In a unique bioregional approach, the reader is taken on a trek through some of Australia's spectacular regional landscapes, highlighting their endemic and special snail faunas. This section is supplemented with key localities where species can be found.

Download or read book Southwood s Ecological Methods written by Peter A. Henderson and published by Oxford University Press. This book was released on 2021 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Methods by the late T.R. E. Southwood and revised over the years by P. A. Henderson has developed into a classic reference work for the field biologist. It provides a handbook of ecological methods and analytical techniques pertinent to the study of animals, with an emphasis on non-microscopic animals in both terrestrial and aquatic environments. It remains unique in the breadth of the methods presented and in the depth of the literature cited, stretching right back to the earliest days of ecological research. The universal availability of R as an open source package has radically changed the way ecologists analyse their data. In response, Southwood's classic text has been thoroughly revised to be more relevant and useful to a new generation of ecologists, making the vast resource of R packages more readily available to the wider ecological community. By focusing on the use of R for data analysis, supported by worked examples, the book is now more accessible than previous editions to students requiring support and ideas for their projects. Southwood's Ecological Methods provides a crucial resource for both graduate students and research scientists in applied ecology, wildlife ecology, fisheries, agriculture, conservation biology, and habitat ecology. It will also be useful to the many professional ecologists, wildlife biologists, conservation biologists and practitioners requiring an authoritative overview of ecological methodology.
Download or read book Saving Sebastian written by Hazel McHaffie and published by Luath Press Ltd. This book was released on 2013-07-22 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time is running out for four-year-old Sebastian Zair. A rare blood disorder means that a stem-cell transplant is his only hope of surviving past childhood. His mother places her trust in the Pemberton Fertility Centre and a controversial IVF procedure which will allow her to select an embryo that is the same tissue type as Sebastian - to create a saviour sibling. But what she doesn't know is that the sword of Damocles is hanging over the Pemberton. A Nigerian couple, the Opakanjos, have just given birth to twins through IVF, but only one is their biological child. Someone has made a monumental mistake. With a major enquiry under way and pro-life campaigners on the warpath, both families are faced with agonising personal choices as well as the intrusions of an unscrupulous journalist. Will they break under the strain? Will Sebastian survive? REVIEWS: There are very few novels which deal with the issues of contemporary medical ethics in the lively and intensely readable way which Hazel McHaffie's books do. ALEXANDER McCALL SMITH McHaffie's books are skillfully written to bring out the complex ethical issues we as doctors, nurses, patients, or relatives, may face in dealing with difficult issues... These books are a welcome development of what has been called the narrative turn in medical ethics. THE BRITISH MEDICAL JOURNAL

Download or read book The Mollusks written by Charles F. Sturm and published by Universal-Publishers. This book was released on 2006 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mollusks have been important to humans since our earliest days. Initially, when humans were primarily interested in what they could eat or use, mollusks were important as food, ornaments, and materials for tools. Over the centuries, as human knowledge branched out and individuals started to study the world around them, mollusks were important subjects for learning how things worked. In this volume, the editors and contributors have brought together a broad range of topics within the field of malacology. It is our expectation that these topics will be of interest and use to amateur and professional malacologists.
