Book excerpt: "The general introduction to the two volumes is including acknowledgements, and the characteristics of the family are in volume one. The list of abbreviations is repeated below and the acknowledgements are completed. The former classifications of subfamilies or tribes are already rather of historical importance; however, in almost every one there are some important facts or interesting interpretations. Within a few last years there has been a consensus in almost all classifications problems. The most actual is the proposal of arrangement of the family-level taxa by Horak (1999) which is also followed in this paper. Contents include: Introduction, Systematics, System of the European Tortricidae, Systematic list of Olethreutinae, Olethreutinae, Plates of Genitalia, Plates of Adults, List of Plants, References, Index."

Download or read book Conifers of the World written by James E. Eckenwalder and published by Timber Press. This book was released on 2009-11-14 with total page 745 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researched for more than three decades, this definitive work provides up-to-date descriptions of all the true conifers of the world, including 545 species of trees and shrubs. Written for accessibility to both horticultural and botanical audiences, it is the first comprehensive update of conifer taxonomy in nearly a century. Noted conifer taxonomist James E. Eckenwalder also discusses the relationships among the groups, practical usages, champion trees, fossil occurrences, and biology. New identification guides for the families and genera are based whenever possible on foliage features and thus should be easier to use than traditional conifer keys, which focus on seasonal, and often microscopic, cone characters. Eckenwalder shares the reasoning behind his taxonomic decisions, many of which are unique to this book, reflecting a comprehensive reevaluation of conifer classification. He also outlines the features sought in cultivars of each genus, particular cultivation concerns, and conifers recommended for cultivation under various conditions and to achieve different effects. Some 3,000 cultivars have been available in recent times, more than five times the total number of conifer species. Several hundred original illustrations include drawings of the seed cones for all genera as well as for representative species. Maps of the natural distribution of each genus allow for easy comparison of ranges. Handsome black-and-white photographs of species in their natural habitats and attractive color photos further enrich the volume. More than 100 images reproduce foliage of many genera as an aid in identification. With its unprecedented attention to detail and extensive bibliography, this major work is an essential reference for botanists, naturalists, and horticulturists.

Available in PDF, EPUB and Kindle. Book excerpt: This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.

This book was released on 2017-09-14 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the key stages of niche-based habitat suitability model building, evaluation and prediction required for understanding and predicting future patterns of species and biodiversity. Beginning with the main theory behind ecological niches and species distributions, the book proceeds through all major steps of model building, from conceptualization and model training to model evaluation and spatio-temporal predictions. Extensive examples using R support graduate students and researchers in quantifying ecological niches and predicting species distributions with their own data, and help to address key environmental and conservation problems. Reflecting this highly active field of research, the book incorporates the latest developments from informatics and statistics, as well as using data from remote sources such as satellite imagery. A website at www.unil.ch/hsdm contains the codes and supporting material required to run the examples and teach courses.

Download or read book Caterpillars in the Field and Garden written by Thomas J. Allen and published by Oxford University Press. This book was released on 2005-06-02 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jeffrey Glassberg's acclaimed Butterflies through Binoculars guides have revolutionized the way we view butterflies. Now there's a field guide in the same practical format, and with the same emphasis on conservation, to identify caterpillars. Caterpillars are as varied, fascinating, and often as colorful as the adult butterflies they become. This is the most comprehensive guide to these creatures available. It contains all the information necessary to find and identify the caterpillars of North America--from Two-tailed Swallowtails, some of the largest butterfly caterpillars at just over two inches when fully grown, to tiny Western Pygmy-Blues. Caterpillar seekers will learn how to distinguish between butterfly caterpillars and moth caterpillars, where and how to find caterpillars, and the visual differences between young and older caterpillars. Each species section describes how to identify the caterpillar, complete with brilliant photos--many published here for the first time. To make for easy field use, each caterpillar's key physical features, abundance, habitat, and major hostplants are listed on the same page as its photo. The book also contains a special section on butterfly gardening, offering valuable information on how to set up a butterfly garden and raise healthy butterfly caterpillars, and provides a thorough list of the plants butterflies most like to feast on. From the concerned gardener who wishes not to kill caterpillars that may one day become beautiful butterflies to the serious butterflier wishing to take the hobby to the next level, this remarkable guide will provide all of the information necessary for an enriching caterpillar experience.

Download or read book Quaternary Glaciations - Extent and Chronology written by J. Ehlers and published by Elsevier. This book was released on 2004-10-02 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the second of three volumes in which the recent knowledge of the extent and chronology of Quaternary glaciations has been compiled on a global scale. This information is seen as a fundamental requirement, not only for the glacial community, but for the wider user-community of general Quaternary workers. In particular the need for accurate ice-front positions is a basic requirement for the rapidly growing field of palaeoclimate modelling. In order to provide the information for the widest-possible range of users in the most accessible form, a series of digital maps was prepared.The glacial limits were mapped in ArcView, the Geographical Information System (GIS) used by the work group. Included with the publication is a CD with digital maps, showing glacial limits, end moraines, ice-dammed lakes, glacier-induced drainage diversions and the locations of key sections through which the glacial limits are defined and dated. The last deglaciation is also shown in 500 year time-steps. The digital maps in this volume cover the USA and Canada and include Greenland and Hawaii. Both overview maps and more detailed maps at a scale 1: 1,000,000 are provided.Also available:Part I: Europe, ISBN 0-444-51462-7Part III: South America, Asia, Africa, Australia, Antarctica, ISBN 0-444-51593-3

Download or read book The Dry Forests and Woodlands of Africa written by Emmanuel N. Chidumayo and published by Routledge. This book was released on 2010-09-23 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dry forests and woodlands of Sub-Saharan Africa are major ecosystems, with a broad range of strong economic and cultural incentives for keeping them intact. However, few people are aware of their importance, compared to tropical rainforests, despite them being home to more than half of the continent's population. This unique book brings together scientific knowledge on this topic from East, West, and Southern Africa and describes the relationships between forests, woodlands, people and their livelihoods. Dry forest is defined as vegetation dominated by woody plants, primarily trees, the canopy of which covers more than 10 per cent of the ground surface, occurring in climates with a dry season of three months or more. This broad definition - wider than those used by many authors - incorporates vegetation types commonly termed woodland, shrubland, thicket, savanna, wooded grassland, as well as dry forest in its strict sense. The book provides a comparative analysis of management experiences from the different geographic regions, emphasizing the need to balance the utilization of dry forests and woodland products between current and future human needs. Further, the book explores the techniques and strategies that can be deployed to improve the management of African dry forests and woodlands for the benefit of all, but more importantly, the communities that live off these vegetation formations. Thus, the book lays a foundation for improving the management of dry forests and woodlands for the wide range of products and services they provide.

Download or read book Landscape Ecology in Theory and Practice written by Monica G. Turner and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ideal text for students taking a course in landscape ecology. The book has been written by very well-known practitioners and pioneers in the new field of ecological analysis. Landscape ecology has emerged during the past two decades as a new and exciting level of ecological study. Environmental problems such as global climate change, land use change, habitat fragmentation and loss of biodiversity have required ecologists to expand their traditional spatial and temporal scales and the widespread availability of remote imagery, geographic information systems, and desk top computing has permitted the development of spatially explicit analyses. In this new text book this new field of landscape ecology is given the first fully integrated treatment suitable for the student. Throughout, the theoretical developments, modeling approaches and results, and empirical data are merged together, so as not to introduce barriers to the synthesis of the various approaches that constitute an effective ecological synthesis. The book also emphasizes selected topic areas in which landscape ecology has made the most contributions to our understanding of ecological processes, as well as identifying areas where its contributions have been limited. Each chapter features questions for discussion as well as recommended reading.
