Download or read book Biological Control of Weeds in Australia written by Jim Cullen and published by CSIRO PUBLISHING. This book was released on 2012-03-05 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological control of weeds has been practised for over 100 years and Australia has been a leader in this weed management technique. The classical example of control of prickly pears in Australia by the cactus moth Cactoblastis cactorum, which was imported from the Americas, helped to set the future for biocontrol of weeds in many countries. Since then there have been many projects using Classical Biological Control to manage numerous weed species, many of which have been successful. Importantly, there have been no serious negative non-target impacts – the technique, when practised as it is in Australia, is safe and environmentally friendly. Economic assessments have shown that biocontrol of weeds in Australia has provided exceedingly high benefit-to-cost ratios. This book reviews biological control of weeds in Australia to 2011, covering over 90 weed species and a multitude of biological control agents and potential agents. Each chapter has been written by practising biological control of weeds researchers and provides details of the weed, the history of its biological control, exploration for agents, potential agents studied and agents released and the outcomes of those releases. Many weeds were successfully controlled, some were not, many projects are still underway, some have just begun, however all are reported in detail in this book. Biological Control of Weeds in Australia will provide invaluable information for biological control researchers in Australia and elsewhere. Agents used in Australia could be of immense value to other countries that suffer from the same weeds as Australia. The studies reported here provide direction to future research and provide examples and knowledge for researchers and students.

Download or read book Invasive Exotic Species in the Sonoran Region written by Barbara Tellman and published by University of Arizona Press. This book was released on 2023-12-19 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: All over the planet, organisms of many species are appearing outside of their natural habitats—often carried by that particularly peripatetic species Homo sapiens. This book marks the first comprehensive attempt to address problems posed by expanding populations of exotic plant and animal species in the Sonoran Desert and adjacent grasslands and riparian areas. It describes the arrival and spread of non-native species as diverse as rats and saltcedar, covering both their impacts and the management of those impacts. It is estimated that as much as 60 percent of the vegetative cover of the Sonoita Creek-Patagonia Reserve, the first Nature Conservancy area designated in Arizona, is dominated by exotic plants, and that introduced fish pose a recurrent threat to the native fish of that area. Meanwhile at the Grand Canyon, invasives such as tamarisk, red brome, carp, and catfish are pervasive either in the Colorado River or in the patches of desert scrub along its shores. Throughout the Sonoran Desert and adjacent areas, from islands in the Sea of Cortés to desert grasslands, some six hundred species of non-native plants and animals have become established, with bullfrogs and Mediterranean grasses now common where they once never existed. The book brings together contributors from academia, government, and nonprofit organizations, including such experts as Gary Paul Nabhan, Richard Mack, and Alberto Búrquez-Montijo. They review historic and even prehistoric origins of non-native species—not only exotic plants, amphibians, and mammals but also insects, fish, and birds. They then examine significant problems in each major subregion and ecosystem and discuss control efforts. The volume contains the first compiled list of more than 500 naturalized exotic species in the Sonoran region. Invasive species issues are rapidly emerging as major environmental concerns both locally and worldwide. This book will assist professionals—ecologists, conservation biologists, and policy makers—involved in invasive species control in the Southwest and will be a rich resource for all concerned with protecting native species and their habitats.
Download or read book Microsporidia written by Louis M. Weiss and published by John Wiley & Sons. This book was released on 2014-10-20 with total page 756 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microsporidia: Pathogens of Opportunity provides a systematic overview of the biology of microsporidia. Written by leading experts in the field, the book combines background and basic information on microsporidia with descriptive methods and resources for working with the pathogen. Newly revised and updated for its second edition, Microsporidia will continue to be the standard text reference for these pathogenic protists, and is an indispensable research resource for biologists, physicians and parasitologists. This new edition of this publication provides systematic reviews of the biology of this pathogen by leading experts in the field, and will be combined with descriptions of the methods and resources for working with this pathogen. • Provides a comprehensive summary of literature on microsporidia and microsporidiosis • The long-awaited update to the standard microsporidia reference text The Microsporidia and Microsporidiosis • Written by an international team of authors representing each of the main research groups working on microsporidia • Chapters provide comprehensive overviews of general methodology as well as special techniques related to these organisms
Download or read book Assessment and Management of Plant Invasions written by James O. Luken and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasion of native plant communities is a high-priority problem in the field of environmental management. Resource managers, biologists, and all those involved in plant communities must consider ecological interactions when assessing both the effects of plant invasion and the long-term effects of management. Sections of the book cover human perceptions of invading plants, assessment of ecological interactions, direct management, and regulation and advocacy. It also includes an appendix with descriptive data for many of the worst weeds.

Download or read book Hymenoptera and Biodiversity written by John LaSalle and published by Oxford University Press, USA. This book was released on 1993 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing attention has been focused on biodiversity in recent years, based on a number of arguments to justify the conservation of the world's flora and fauna. Such arguments may be economic - that species may have potential for food or medicine - or ecological - that the extinction of any species affects the overall ecological balance. Little attention, however, has been focused on which groups have the greatest impact on maintaining diversity. Hymenoptera is one of these groups. It not only forms a major component of diversity itself, but is vital in sustaining diversity in other groups. Hymenoptera species (bees, wasps, ants and sawflies) are major plant pollinators, seed dispersers and parasitoids and predators of other arthropods (and hence important in biological control). This volume therefore tackles an important subject and concentrates on three key issues: how species of Hymenoptera affect diversity in other organisms; whether Hymenoptera is a group prone to extinction; and the consequences if Hymenoptera species are differentially removed from terrestrial ecosystems. The book is essential reading for entomologists and those concerned with biodiversity and conservation.
