Reptiles have been a topic for scientific study for many decades and remain widely studied around the world. In particular, their reproductive patterns and strategies have been extensively studied, proving useful in analysis of life-history strategies. A pivotal aspect of reptilian reproduction is incubation of eggs. Oviparity is found in all turtles, crocodilians and the tuatara and is prevalent in many lizards and snakes. Many aspects of the eggs, embryos and incubation conditions have been the subject of numerous scientific reports. This volume is dedicated to systematic analysis of reptilian incubation. The concept for the book is to look at reptilian eggs, development and incubation conditions in a functional way with particular emphasis on the natural incubation environment and, rather than concentrating on Family accounts, (e.g. incubation in crocodilians) the chapters review the topics in all reptile types allowing for the first time a systematic comparison of incubation between crocodilians, turtles and squamates. In addition to reviewing current information, the authors briefly look towards the future and outline areas where further research is needed.

Nests, Eggs, and Incubation brings together a global team of leading authorities to provide a comprehensive overview of the fascinating and diverse field of avian reproduction. Starting with a new assessment of the evolution of avian reproductive biology in light of recent research, the book goes on to cover four broad areas: the nest, the egg, incubation, and the study of avian reproduction. New research on nest structures, egg traits, and life history is incorporated, whilst contemporary methodologies such as self-contained temperature probes and citizen science are also discussed. Applied chapters describe how biological knowledge can be applied to challenges such as urbanisation and climate change. The book concludes by suggesting priorities for future research. This book builds upon the foundations laid down by Charles Deeming's 2002 work Avian Incubation (available for readers of this book to access online for free), much of which remains relevant today. Read in conjunction with this previous volume, it provides an up-to-date and thorough review of egg biology, nest function, and incubation behaviour, which will be an essential resource for students of avian biology, as well as both professional and amateur ornithologists working in the field of avian reproduction.

Despite their diversity, amphibians and reptiles share many physiological traits, such as their dependence on external heat sources for body temperature regulation, that are of pivotal importance to their ability to cope with the environment. Considerable variation in physiological capabilities exists in these groups and often can be related to seasonal and geographic differences in environmental parameters. This book provides a comprehensive and integrative view of the interplay between physiology and behavior in amphibians and reptiles, leading to a better understanding of the subject. The book covers topics that have recently been in the spotlight for scientific research on the physiology, behavior, and conservation of amphibians and reptiles. It brings together recent information from a range of disciplines that address critical topics for understanding their biology. As these studies are scattered across articles in specialized journals, this book provides a single and expanded source summarizing such advancements. Amphibian and Reptile Adaptations to the Environment: Interplay Between Physiology and Behavior maintains a solid scientific basis for the biological topics covered. However, it presents the material in a clear and direct manner so that it is accessible even to non-biologists interested in the basic biology, behavior, and ecology of these animals as well as how these elements are connected to their conservation.

Featuring in-depth contributions from an international team of experts, the Biology of Turtles provides the first comprehensive review of the Testudinata. The book starts with the premise that the structure of turtles is particularly interesting and best understood within the context of their development, novelty, functional diversity, and evolution. It provides a robust discussion of the development and diversity of the shell. The book also explores the turtle body plan, its physiological and ecological consequences, evolutionary novelties, and their importance. The 200 illustrations found throughout the text enhance the chapters combine with color illustrations of the development of the shell, aspects of bone structural diversity, growth, and skeletochronology, to make this book an unparalleled resource. The volume concludes with a thoughtful discussion of the more than century long debate on the origins of turtles and the reasons why our understanding of the phylogenic origins and evolution of turtles remains tentative. Currently available books on this subject are woefully out of date and no overall review of Testudinata has been undertaken...until now. Each chapter represents a milestone in synthesizing a wide range of available information on specific subjects. The book’s challenge: look both inside and outside the shell to build a clearer understanding of the diversity and evolution of turtles.

This volume collects selected papers from the 3rd ICCPB in Africa: Animals and Environments. A wide and integrated discussion of how animals persist in their normal habitats aims to improve our appreciation of animal interaction with, and response to, environment. In a time of persistent reductionism in biological studies, the collected papers discuss both breadth and depth of adaptive animal biology from more holistic perspectives. The discussion ranges from unicellular organisms to whole animals. Themes include; molecular bases of physiological response to hypoxia and the role of hypoxia inducible factors; adaptive mechanisms of ion homeostasis in crustaceans, signaling and respiration in insects; aspects of metal contamination; extremes of temperature and water availability; foraging, predation, and the acquisition of food; in the light of specific environmental demands. This volume will be of specific interest researchers in the field of adaptive molecular and evolutionary physiology and biochemistry. Biologists interested in how animals respond to their environment - be it with a molecular, physiological or ecological emphasis will find the breath of issues both stimulating and informative. "Animals and Environments" collates works in Comparative and Evolutionary Physiology and Biochemistry - covering a range of subject material and approaches seldom brought together in a single volume. Inclusion in a single volume of molecular, biochemical and physiological material aimed at addressing adaptation to environment Many of the individual works are reviews in their own right and provide an excellent resource. The diversity of approaches and material examining the evolution of adaptive mechanisms.

Here is the first complete portrait of the legendary flying dragons of deep time-the pterosaurs-designed for non-specialists, yet founded on the real science of these bizarre creatures. Presented lucidly and accessibly by one of the world's leading experts, David Unwin's book is built on a mountain of new fossil discoveries and the latest research. About 220 millions years ago, a group of reptiles took to the Earth's vast and open skies. No longer tethered to the ground, the earliest pterosaurs evolved into a multitude of diverse forms, spread around the globe, and ruled the skies until they went extinct along with the dinosaurs about 65 millions years ago, rarely leaving fossils as a record of their existence. What they did leave was a mystery for paleontologists to solve; an enigma so difficult to crack that it took centuries of false starts and missteps before the path to a true understanding of pterosaurs was uncovered. Now, an understanding of the fundamental nature of these strange creatures is finally possible. In the last 15 years, stunning new fossil finds and significant advances in technology have led to a breakthrough in our knowledge of pterosaurs. New fossils of the earliest species were discovered in Italy, a remarkably well-preserved and complete wing was found in Central Asia, and, most extraordinarily, a pterosaur embryo inside an egg was unearthed in China. CAT scanning has let researchers glimpse inside pterosaur skulls and construct three-dimensional images of their bodies from crushed bones, and modern techniques for analyzing relationships between species have revealed surprising insights into the evolution of the group. Drawing on these and other advances, DavidUnwin, caretaker of Archaeopteryx and curator at the Museum of Natural History in Berlin, paints pterosaurs and their world more vividly than has previously been possible. He eloquently reconstructs their biology and behavior. Pterosaurs weren't scaly like dinosaurs, but hairy; most were brightly colored and adorned with remarkable head crests; they were excellent fliers with physiologically sophisticated wings; they walked on all fours; and varied in size from eight inches to forty feet in wingspan. He shows how they lived their lives, raised their young, and interacted with the different environments of Mesozoic Earth. Then, building on his thorough examination of their anatomy and lifestyle, and using the powerful technique of cladistic analysis, Unwin unravels the evolutionary history of pterosaurs and establishes their place in the one great tree of life. Packed with 95 color and 30 black and white illustrations-including 10 full-page original color paintings that are scientific recreations of different pterosaur species-"The Pterosaurs From Deep Time" takes readers on an wondrous expedition back through the lost world of the Earth's deep past.
