Biological Systems in Vertebrates – serie

This book deals with reproduction of Amphibians belonging to three extant orders: Caecilians, Salamanders, Frogs and Toads. Separate chapters have been written for males and females; the chapters describe gonad structure and development, gametogenesis, urogenital connections, and reproductive tracts. The authors have provided a synthesis of the literature data and results of their own studies. The text is illustrated with original schemes and photographs and focuses on anatomy, histology, cytology, and molecular mechanisms that regulate gametogenesis and reproductive cycles. The first chapter is devoted to the origin of somatic and germ cells during formation of undifferentiated gonads. The last chapter deals with embryonic and postembryonic development, direct development, neoteny, and modifications of gametogenesis and meiosis in hybrids and polyploids (hybridogenesis and gynogenesis). The book will interest all reproductive biologists and biologists working on amphibians.

Gives an account of the morphologies of vertebrate respiratory organs and attempts to explicate the basis of the common and different structural and functional designs and stratagems that have evolved for acquisition of molecular oxygen. The book has been written with a broad readership in mind: students of biology as well as experts in the disciplines of zoology, physiology, morphology, biological microscopy, biomedical engineering, and ecology and those that work or may contemplate working on materials and aspects concerning respiration in whole organisms will find it useful. Scientists in earth sciences with particular interest on the outcomes of past interactions between environmental factors (the physical domain) and evolution and adaptation (the biological domain), mechanisms that have set the composition, patterning, and anatomies of extant animal life, will find the book of interest.

Describing the diversity and features of various vertebrate groups, ranging from the oldest living fishes to the relatively more recent evolution of mammals, this book covers anatomical systems including organs and tissues, as well as their function and differentiation in various vertebrate groups. The authors also discuss the evolution of vertebrate groups from the earliest extinct ancestors to current living vertebrates. The book contains illustrations to clarify various issues as well as discussions of vertebrate features that enable adaptation to aquatic and terrestrial environments.

The book describes the diversity and features of various vertebrate groups, ranging from the oldest living fishes to the relatively more recent groups to evolve such as mammals. The authors cover the structures of body systems including organs and tissues, as well as their functions and how they differ in various vertebrate groups. They also discuss the evolution of vertebrate groups from the earliest extinct ancestors to the living vertebrates as well as related groups that are now extinct. The book contains illustrations to clarify various issues and discussions of the features that enable vertebrates to adapt to aquatic and terrestrial environments they inhabit.
