This book appears at a time when molecular cytogenetics is positioned to make a significant impact upon evolutionary studies, enabling problems of chromosomal structure and change to be critically assessed. It is an up-to-date and comprehensive survey of the cytogenetics of a major class of animals, including all three amphibian orders, with chapters authored by international leaders in the field.Amphibian Cytogenetics and Evolution will be of interest to classical and molecular cytogeneticists, systematicists, evolutionary biologists, herpetologists, and anyone using amphibians in genetic research. Offers the only current and comprehensive survey of amphibian cytogenetics Gives authoritative and in-depth coverage of topics of present interest Reviews general cytogenetic topics Presents new insights into evolutionary changes in chromosome structure and amphibian phylogeny and relationships including: Phylogenetic analysis of chromosome data, Current techniques of cytogenetic analysis, Examination of all three amphibian orders

'The Chromosomes of Terraranan Frogs' is the most comprehensive, original and comparative cytogenetic study of vertebrates ever performed, presenting results obtained over a 36-year period of more than 70 expeditions to the Neotropics (Central and South America and the Caribbean) and from several laboratories (Canada, Costa Rica, Cuba, Germany, USA, and Venezuela). The karyotypes and genomes of 227 recognized species and 2,548 individual specimens of Terrarana were examined using a variety of staining techniques, molecular probe in situ hybridization, and genome size measurements. Furthermore, all previously published data on the cytogenetics of Terrarana have been included. The karyotype characters were mapped onto the molecular phylogeny obtained by analyses of several mitochondrial and nuclear genes. This allowed reconstruction of the various karyophylogenies as well as calculation of the chromosomal mutation rates. The results were always interpreted in context with the cytogenetic data published for other amphibian taxa or vertebrates. The general properties of eukaryote chromosomes, the rules governing structural and numerical chromosome repatterning as well as the principles of chromosome evolution are explained. An extensive 'Material and Methods' section was compiled with the intention of providing the necessary guidance for everyone interested in studying amphibian chromosomes. This monograph provides detailed current and archival information on terraranan karyotypes and genomes to colleagues who are already recognized specialists in amphibian or vertebrate cytogenetics. It is also valuable reading for herpetologists involved in the evolution of neotropical amphibians and provides comprehensive insights into vertebrate cytogenetics for students.

This monograph is a comprehensive study of arboranan frogs (families Hylidae, Phyllomedusidae, and Pelodryadidae). It presents results achieved over a 38-year period. As arboranan frogs are practically cosmopolitan, absent only from sub-Saharan Africa and southeastern Asia, this publication is an international venture with collaborators from Australia, Brazil, Canada, Ecuador, Germany, Thailand, and the USA. Introductory chapters cover phylogeny, classification, biogeography, life history, and population declines of Arboranae, but the focus of the book is on oogenesis, spermatogenesis, early embryogenesis, and, especially, the structure and evolution of chromosomes. Like its predecessors on terraranan and hemiphractid frogs (2010 and 2012, respectively), this volume represents an immense initiative to assemble all available information on the cytogenetics of a very large monophyletic group of frogs. It also shows the substantial effort being made to provide new data with everything properly placed in a phylogenetic, evolutionary, and biogeographic framework.

The Evolution of the Genome provides a much needed overview of genomic study through clear, detailed, expert-authored discussions of the key areas in genome biology. This includes the evolution of genome size, genomic parasites, gene and ancient genome duplications, polypoidy, comparative genomics, and the implications of these genome-level phenomena for evolutionary theory. In addition to reviewing the current state of knowledge of these fields in an accessible way, the various chapters also provide historical and conceptual background information, highlight the ways in which the critical questions are actually being studied, indicate some important areas for future research, and build bridges across traditional professional and taxonomic boundaries. The Evolution of the Genome will serve as a critical resource for graduate students, postdoctoral fellows, and established scientists alike who are interested in the issue of genome evolution in the broadest sense. Provides detailed, clearly written chapters authored by leading researchers in their respective fields Presents a much-needed overview of the historical and theoretical context of the various areas of genomic study Creates important links between topics in order to promote integration across subdisciplines, including descriptions of how each subject is actually studied Provides information specifically designed to be accessible to established researchers, postdoctoral fellows, and graduate students alike

There Is A Paradox In The Growth Of Scientific Knowledge. As Information Accumulates In Ever More Intimidating Quantities, Disconnected Facts And Impenetrable Mysteries Give Way To Rational Explanation, And Simplicity Emerges From Chaos. Gradually The Essential Principles Of A Subject Come Into Focus. This Is True Of Cell Biology Today. Cell Is A Vital Unit Of Organism And It Can Be Considered As The Anatomic And Physiologic Substrate Of Biologic Phenomena. Most Of The Indian Universities Have Recognized The Importance Of Cell In Due Time And Have Incorporated The Cell Biology, Molecular Biology, Genetics, And Evolution In Their Syllabi.This Book Is Principally For Students Taking A First Course In Cell Biology, Be They Undergraduates, Graduate Students, Or Medical Students. Although Most Readers Have Had At Least An Intro0Ductory Biology Course, The Authors Have Attempted To Write The Book So That Even A Stranger To This Branch Could Follow It By Starting At The Beginning. Most Of The Chapters Have Been Updated To Give The Reader A Current View.
