Available in PDF, EPUB and Kindle. Book excerpt: "Parrots of the Wild is an exhaustive compendium of information about parrots, from their evolutionary history to their behavior to present-day conservation issues. A must-have for anyone interested in these amazing creatures." —Irene M. Pepperberg, Professor at Harvard University and author of Alex & Me: How a Scientist and a Parrot Discovered a Hidden World of Animal Intelligence—and Formed a Deep Bond in the Process "If you like parrots then you'll love this book. From their evolutionary past to their modern-day love lives, Parrots of the Wild presents a suitably captivating read. I thought I knew a lot about parrots--until I delved into these pages." —Tony Juniper, author of What Has Nature Ever Done for Us? and Spix’s Macaw: The Race to Save the World’s Rarest Bird Parrots of the Wild explores recent scientific discoveries and what they reveal about the lives of wild parrots, which are among the most intelligent and rarest of birds. Catherine A. Toft and Tim Wright discuss the evolutionary history of parrots and how this history affects perceptual and cognitive abilities, diet and foraging patterns, and mating and social behavior. The authors also discuss conservation status and the various ways different populations are adapting to a world that is rapidly changing. The book focuses on general patterns across the 350-odd species of parrots, as well as what can be learned from interesting exceptions to these generalities. A synthetic account of the diversity and ecology of wild parrots, this book distills knowledge from the authors’ own research and from their review of more than 2,400 published scientific studies. The book is enhanced by an array of illustrations, including nearly ninety color photos of wild parrots represented in their natural habitats. Parrots of the Wild melds scientific exploration with features directed at the parrot enthusiast to inform and delight a broad audience.

This book was released on 2018-05-08 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean covers 70 percent of the Earth’s surface, and is essential for life on our planet – even for those of us who live nowhere near the sea! It provides us all with food and other materials that we need, regulates our climate and provides half of the oxygen we breathe. The ocean also offers us various means of transport and opportunities for recreation. People have long thought that the ocean was so wide and bountiful that it would go on supplying our needs forever, but this is not the case: human activities are causing significant damage to life in the ocean. People are often unaware of the problems created by this heavy reliance, as few of us have the opportunity to look beneath the surface of the sea and see the damage that our actions have caused. This is where the Ocean Challenge Badge comes in: let it take you on a journey to discover the ocean! It is packed with activities to help you learn about how the ocean works, the creatures that live in it, and just how important it is in our everyday lives. You will also discover how YOU can play a role in protecting our ocean for future generations. We hope you will be inspired to take the challenge and celebrate our ocean. So dive in and begin your aquatic discoveries!

Download or read book Cochrane Handbook for Systematic Reviews of Interventions written by Julian P. T. Higgins and published by Wiley. This book was released on 2008-11-24 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Healthcare providers, consumers, researchers and policy makers are inundated with unmanageable amounts of information, including evidence from healthcare research. It has become impossible for all to have the time and resources to find, appraise and interpret this evidence and incorporate it into healthcare decisions. Cochrane Reviews respond to this challenge by identifying, appraising and synthesizing research-based evidence and presenting it in a standardized format, published in The Cochrane Library (www.thecochranelibrary.com). The Cochrane Handbook for Systematic Reviews of Interventions contains methodological guidance for the preparation and maintenance of Cochrane intervention reviews. Written in a clear and accessible format, it is the essential manual for all those preparing, maintaining and reading Cochrane reviews. Many of the principles and methods described here are appropriate for systematic reviews applied to other types of research and to systematic reviews of interventions undertaken by others. It is hoped therefore that this book will be invaluable to all those who want to understand the role of systematic reviews, critically appraise published reviews or perform reviews themselves.
