Bøger i Biological Systems in Vertebrates serien

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. This book covers the structures of body systems including organs and tissues, as well as their functions and how they differ in various vertebrate groups.

Deals with reproduction of Amphibians belonging to three extant orders: Caecilians, Salamanders, and Frogs and Toads. This book describes gonad structure and development, gametogenesis, urogenital connections, and reproductive tracts. It focuses on anatomy, histology, and molecular mechanisms that regulate gametogenesis and reproductive cycles.

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.

An account of the different morphologies of vertebrate respiratory organs and structures. It explains the essence of different functional designs and strategies that have adaptively developed for the acquisition of molecular oxygen and elimination of carbon dioxide.
