Book Description
"The Megapodes are an ancient and remarkable group of birds that occur only in Australia, Papua New Guinea and the islands that surround them. Within this group, there are 22 species of mound-builders, three of which occur in Australia in dramatically differing habitats. Mound-builders are unique in being the only birds that do not incubate their eggs using body heat; rather, a variety of naturally occurring sources of heat is exploited such as solar energy, geothermal and, most commonly, the heat generated by decomposing organic matter. This book shows how this remarkable adaptation influences every part of these birds lives, including the development of the embryo, the parentless life of the hatchlings, their social organisation and their survival."--Provided by publisher.

Book Description
This book offers exchanges between the fields of paleontology and zoology as patterns of biodiversity have long attracted the attention of both biologists and paleontologists. It covers the development of isolated island faunas, paleogeography and zoomorphology. The book shows that patterns are not always what they seem if looked at without a spatial or temporal reference.

Book Description
A revelatory investigation into how America is failing its children, and an urgent manifesto on why helping them is the best way to improve all of our lives—from the New York Times bestselling author of Unfair: The New Science of Criminal Injustice “Compelling . . . an extremely sympathetic and worthy attempt to protect kids . . . [Benforado] has written a book that reads like a manifesto. His ideas are bold, to the point, and ambitious.”—The Atlantic At the dawn of the twentieth century, a bright new age for children appeared on the horizon, with progress on ending child labor, providing public education, combating indigence, promoting wellness, and creating a juvenile justice system. But a hundred years on, the promised light has not arrived. Today, more than eleven million American children live in poverty and more than four million lack health insurance. Each year, we prosecute thousands of kids as adults, while our schools crumble. We deny young people any political power, while we fail to act on the issues that matter most to them: racism, inequality, and climate change. Through unforgettable stories, law professor Adam Benforado draws a vivid portrait of our neglect. We are there when Ariel is placed in an orphanage after her parents are locked away for transporting marijuana, when Harold first gazes in disbelief upon the immaculate lawn of an elite private school after a childhood of asphalt play yards, when Wylie is hit with a paddle by his public-school principal as punishment for taking a moment of silence to protest gun violence. When Tyler runs for governor at age seventeen, we are also there to witness the extraordinary capacities of young people. Our disregard for children’s rights is not simply a moral problem; it’s also an economic and social one. The root cause of nearly every major challenge we face—from crime to poor health to unemployment—can be found in our mistreatment of kids. But in that sobering truth is also the key to changing our fate as a nation. Drawing on the latest research on the value of early intervention, investment, and empowerment, A Minor Revolution makes the urgent case for putting children first—in our budgets and policies, in how we develop products and enact laws, and in our families and communities. Childhood is the window of opportunity for all of us.

Book Description
With more than 10,000 species that vary in size, use diverse habitats that extend across latitudes and altitudes, consume a wide variety of food items, differ in how they fly (or not), communicate, and reproduce, and have different life histories, birds exhibit remarkable variation in form (anatomy) and function (physiology). Our understanding of how natural selection has generated this variation as birds evolved and as different species adapted to their unique circumstances has grown considerably in recent years. In In a Class of Their Own: A Detailed Examination of Avian Forms and Functions, this variation is explained in great detail, beginning with an overview of avian evolution and continuing with information about the structure and function of the avian skeleton, muscles, and the various body systems. Other chapters focus on avian locomotion (including flight), migration, navigation, communication, energy balance and thermoregulation, and various aspects of avian reproduction, such as nests and nest building, clutch sizes, and parental care. In a Class of Their Own: A Detailed Examination of Avian Forms and Functions will be must reading for anyone, professional or non-professional, who needs or wants to learn more about birds.
