Biological Invasions in Changing Ecosystems
Author: João Canning-ClodePublisher: Walter de Gruyter GmbH & Co KG
ISBN: 3110438666
Category : Science
Languages : en
Pages : 488
Book Description
When organisms are deliberately or accidentally introduced into a new ecosystem a biological invasion may take place. These so-called ‘invasive species’ may establish, spread and ecologically alter the invaded community. Biological invasions by animals, plants, pathogens or vectors are one of the greatest environmental and economic threats and, along with habitat destruction, a leading cause of global biodiversity loss. In this book, more than 50 worldwide invasion scientists cover our current understanding of biological invasions, its impacts, patterns and mechanisms in both aquatic and terrestrial systems.
Biological invaders in inland waters: Profiles, distribution, and threats
Author: Francesca GherardiPublisher: Springer Science & Business Media
ISBN: 1402060297
Category : Science
Languages : en
Pages : 735
Book Description
Invasive species have come to dominate 3% of the Earth’s ice-free surface, constituting one of the most serious ecological and economic threats of the new millennium, and freshwater systems are particularly vulnerable. This book examines the identity, distribution, and impact of freshwater non-indigenous species and the dynamics of their invasion. It focuses on old and new invaders and provides a starting point for further research.

Book Description
"Amphibians are facing an extinction crisis, but getting to the facts has been difficult. "Threatened Amphibians of the World" is a visual journey through the first-ever comprehensive assessment of the conservation status of the world's 6,000 known species of frogs, toads, salamanders, and caecilians. All 1,900 species known to be threatened with extinction are covered, including a description of threats to each species and an evaluation of conservation measures in place or needed. Each entry includes a photograph or illustration of the species where available, a distribution map, and detailed information on range, population and habitat and ecology. Introductory chapters present a detailed analysis of the results, complemented by a series of short essays written by many of the world's leading herpetologists. Appendices include annoted lists of lower risk species and a country-by-country listing of threatened amphibians."--pub. desc.

Book Description
"The premiere reference book on the 108 species of frogs inhabiting North America north of Mexico. An unparalleled synthesis of the biology and behavior of all native and nonindigenous species, this two-volume, extensively referenced resource has been called the most important book ever published on North American anura. Color photographs and range maps accompany species accounts detailing information on etymology, nomenclature, identification, distribution, fossil record, systematics and geographic variation, life history and ecology, behavior, population and community biology, and conservation. This new edition of the text contains the following updates: Literature citations have been added from 2012 to 2021, now spanning from 1709 to 2021. Distribution maps have been updated, recording the decreased ranges due to declining amphibian populations. Photographs have been revised to ensure the highest digital quality. Anaxyrus williamsi and Lithobates kauffeldi, newly described species, have been included. An account is also included for Gastrophryne mazatlanensis, now recognized as occurring within the United States. Generic keys have been added. A brief section on N.A. frogs in history and art have been added. Nomenclature has been updated (Incilius for Ollotis). Now the only up-to-date and comprehensive resource for those trying to protect amphibians in the US and Canada, as well as for researchers and wildlife managers who study biodiversity"--
