Download or read book Owls of the World A Photographic Guide written by Heimo Mikkola and published by Bloomsbury Publishing. This book was released on 2020-09-06 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Having trouble separating your scops from your screech owls, Tengmalm's from Tawny Owl or Collared and Spotted Owlets? Then this is the book for you. Owls of the World is the ultimate photographic resource dedicated to the identification of these charismatic, largely nocturnal birds of prey. This book contains lavish and spectacular photography from dozens of the world's finest natural history photographers, covering all of the world's 268 species of owls; particular attention is given to subspecific differences, sexing and ageing. The photos are accompanied by concise text on the identification, habitat, food, distribution and voice of these birds, along with accurate range maps. In this second edition, recent changes to owl taxonomy are incorporated with full descriptions (and images) of a number of new species, plus a several new photographs to improve this book's amazing photographic coverage still further. This is the definitive work on owl identification – no birder's bookshelf should be without it!
Download or read book Invasive Alien Species written by Michael R. Ielmini and published by John Wiley & Sons. This book was released on 2021-04-21 with total page 1488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jedes Jahr breiten sich invasive gebietsfremde Arten in neue Ökosysteme aus. Die von den Eindringlingen verursachten Auswirkungen können sich in kürzester Zeit bemerkbar machen und verheerend sein. Das Thema der invasiven gebietsfremden Arten ist umfassend, komplex und auf verschiedenen Ebenen von globaler Bedeutung. Verschärft wird es durch die Globalisierung der Weltwirtschaft und den zunehmenden Handel, durch den die natürlichen Barrieren für den Transfer von Arten durchbrochen werden. Invasive gebietsfremde Arten bedrohen die weltweite Nahrungsmittelversorgung, die Qualität und Verfügbarkeit von Trinkwasser sowie die Stromproduktion und -versorgung. Zusammen mit den zusätzlichen Risiken durch den globalen Klimawandel ist die weltweite Homogenisierung von Pflanzen, Tieren und Mikroben ein wesentlicher Faktor für den sich verschlechternden Gesundheitszustand der Ökosysteme und die nachlassenden Ökosystemdienstleistungen überall auf der Welt. Um dieser Entwicklung entgegenzuwirken, besteht die dringende Notwendigkeit einer einheitlichen Ausrichtung von Regierungen, Kulturen und Programmen und einer besseren grenzüberschreitenden Koordination. Nur so lassen sich die vielfältigen Bedrohungen durch invasive gebietsfremde Arten für die Umwelt, die Wirtschaft und die Gesundheit von Pflanzen und Tieren sowie insbesondere die menschliche Gesundheit effektiv bekämpfen. Dieses vierbändige Werk ist das erste, das einen umfassenden Satz nützlicher Materialien zu den zentralen Themen bereitstellt, um die gesamte globale Bedrohung durch invasive gebietsfremde Arten sowie die vielfältigen Probleme in verschiedenen Teilen der Welt deutlich zu machen, und es enthält Material, in dem potenziell replizierbare Lösungen zur Überwindung dieser Bedrohungen aufgezeigt werden. Das Werk betont die Bedrohung durch invasive gebietsfremde Arten auch im Sinne eines globalen ?Aufrufs zum Handeln?. Invasive Arten kennen keine Grenzen. Daher hoffen wir, dass wir durch die Zusammenstellung von Material, das unterschiedliche wissenschaftliche und gesellschaftliche Standpunkte aus aller Welt berücksichtigt, sowie durch die Vermittlung von Erkenntnissen und Beispielen zu einer Vielzahl damit zusammenhängender Themen das globale Bewusstsein stärken und einheitliche nationale Reaktionen auf die Bedrohung durch invasive gebietsfremde Arten fördern können.
Download or read book California Amphibian and Reptile Species of Special Concern written by Robert C. Thomson and published by Univ of California Press. This book was released on 2016-06-21 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most important hotspots of herpetological biodiversity in the United States, California is home to many endemic amphibians and reptiles found nowhere else on earth. Many of these taxa have unique ecological and morphological specializations, and their management is an important conservation challenge. Increasing climate change impacts, human development, and extreme drought mean many of these species face an ever-greater risk of extinction. California Amphibian and Reptile Species of Special Concern provides an up-to-date synthesis of the current state of knowledge regarding the biology and conservation risks faced by 45 of California’s most sensitive amphibian and reptile species. With the goal of enhancing management based on the best available science, the authors developed a novel set of risk metrics to identify special concern species and the threats they face, including population declines, range size and restrictions, and ecological specializations and niche restrictions. In addition to detailed species accounts, this book provides a quantitative analysis of the conservation status and pressing management issues facing individual species and the state’s amphibian and reptile fauna as a whole. The volume focuses on identifying threats, concrete recommendations for management and recovery, and future research needs. The text is complemented by detailed distribution maps, color photos, and graphs. Written in nontechnical language, California Amphibian and Reptile Species of Special Concern will be a valuable resource to a broad range of users from resource managers, field biologists, and academic herpetologists to students and recreational naturalists. Published in association with the California Department of Fish and Wildlife.

Download or read book Ancient Animals New Challenges written by Manuel Maldonado and published by Springer. This book was released on 2015-03-21 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the latest advances in sponge science through a concise selection of studies presented at the VIII World Sponge Conference. The collection of articles reflects hot, ongoing debates in molecular research, such as the monophyletic versus paraphyletic nature of the sponge group, or the new awareness on pros and cons of standard barcodes and other markers in sponge taxonomy and phylogeny. It also features articles showing how the new sequencing technologies reveal the functional and phylogenetic complexity of the "microbial universe" associated to sponge tissues. The ecological interactions of sponges, the effects of nutrients and pollutants, the variability in reproductive patterns, and the processes generating genotypic and phenotypic variability in sponge populations are covered in several contributions. Zoogeography, population structure and dynamics are also approached with both traditional and molecular tools. The effect of anthropogenic disturbance on the natural environment finds its place in this volume with papers dealing with metal accumulation and the potential role of sponges as biomonitors. Biodiversity data from unexplored tropical and deep sea areas are presented. We hope readers will enjoy the selection of papers, which we believe represent collectively a significant contribution to our current understanding of sponges.

This book was released on 1995-08-31 with total page 832 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multi-disciplinary approach to conservation of endangered species in captivity is organized taxonomically and by scientific discipline. The seven taxonomic groups included are invertebrates; fish, reptiles and amphibians, birds, marine mammals, primates, and other mammals. Within each taxonomic group, four scientific disciplines are explored: conservation, reproductive physiology, behavior, and captive design. Conservation chapters summarize the status of the taxonomic group both in the wild and in captivity. Reviewed in the reproductive physiology chapters are anatomy, endocrinology and physiology for females and males of the taxonomic group. In the section on behavior the functions of captive animal research, the methods used, and the problems encountered are discussed. And, in examining captive design the authors provide a general historical outline of the philosophies, trends, and scientific issues for the targeted taxonomic group.
