Fish represent the most ancestral and specious group of vertebrates, and occupy more diverse aquatic environments around the world. Ichthyofauna is extremely diverse, especially in megadiverse countries occupying biogeographical regions such as the Neotropical Region, which covers an extensive area between North and South America. Much of this biodiversity will be extinct, even before science knows any aspect of its biology. Like this, Neotropical fish genetics started in the end of the 70’s with papers studying the chromosomes of Hoplias malabaricus (Family Erythrinidae) and the karyotype variation among three genera of the family Anostomidae. The topic at that time was concentrated in tw...
This topic has been realized, and is in collaboration with Dr. Constanze Pentzold, Post Doctoral Researcher at the Institute of Human Genetics, University Hospital Jena.
Although Gregor Mendel is considered the father of genetics, he has never taken the credit for his principles on heredity. Mendel's treatises, though they were part of the collection of the largest European libraries in the 19th century, were only rediscovered in 1900, 16 years after his death. Mendel's revolutionary ideas would have given greater strength to the formulation of Charles Darwin's ideas about common descent and gradual evolution through natural selection presented in 1859 in "The Origin of Species." However, Darwin was not totally ignorant of the possibility of genetic heredity. He even described “invisible characters” emerging in atavistic situations and named his hypothet...
Nesta coleção a intenção foi reunir, em uma obra didática, sucinta e objetiva os fatos mais recentes na literatura com os conhecimentos clássicos dos temas disponíveis em obras separadas. Para se ter todo o escopo de Biotecnologia Aplicada à Saúde e Biotecnologia Aplicada à Agro&indústria, dividimos o primeiro tema em três volumes e o segundo em um, totalizando 4 volumes, sendo que todos os tópicos são abordados nos cursos de pós-graduação em Biociências e Biotecnologia, dentre outros. Seguindo essa direção e no sentido de produção de um livro que seja para o uso de, tanto alunos de graduação quanto os de pós-graduação e para aqueles profissionais que queiram se in...
Vascular surgery has experienced remarkable growth and diversification in the last decade, especially with its embracing the disruptive endovascular technological revolution. Vascular surgeons remain the only group of specialists capable of total treatment of patients with vascular disease, providing medical, minimally invasive, and surgical therapy. Although vascular surgeons practice in all areas of the world, practice patterns in different areas naturally have both similarities and differences that reflect both regional patterns of disease, genetic characteristics of local peoples, cultural preferences for treatment, local political and economic situations, different access to resources a...
The experimental data that have been generated using new molecular techniques associated with the completion of genome projects have changed our perception of the structural features, functional implications and evolutionary dynamics of repetitive DNA sequences. This volume of Genome Dynamics provides a valuable update on recent developments in research into multigene families, centromeres, telomeres, microsatellite DNA, satellite DNA, and transposable elements. Each chapter presents a review by distinguished experts and analyzes repetitive DNA diversity and abundance, as well as the impact on genome structure, function and evolution. This publication is targeted at scientists and scholars at every level, from students to faculty members, and, indeed, anyone involved or interested in genetics, molecular evolution, molecular biology as well as genomics will find it a valuable source of up-to-date information.
As the largest group of extant vertebrates, fish offer an almost limitless number of striking examples of evolutionary adaptation to environmental and biotic selection pressure. The most diverse of all vertebrate groups, the higher taxa of fish traditionally have been classified by morphology and paleontology, with a much smaller input of cytogenetic information. DNA sequence data are exerting an increasingly strong influence on modern fish systematics, challenging the classification of numerous higher taxa ranging from genera to orders. The most fruitful approach, however, involves synthetic analyses of morphology, molecular phylogenetics, comparative karyology, and genome size. Karyotypes of more than 3400 species/subspecies are arranged here by fish systematics and include a list of genome size, sex chromosomes, B chromosomes, polyploidy, and locality of material fish, among others. This volume enables both beginners and advanced researchers to survey the existing literature and facilitates the implementation of an integrative approach to fish systematics. The first book on fish chromosomes in nearly 15 years, it is also the most comprehensive.
Since 1997, scientists of different disciplines sharing a deep interest in concepts and knowledge related to evolutionary biology have held the annual Evolutionary Biology Meetings in Marseille in order to discuss their research and promote collaboration. Lately scientists especially focusing on applications have also joined the group. This book starts with the report of the "12th Evolutionary Biology Meeting", which gives a general idea of the meeting’s epistemological stance. This is followed by 22 chapters, a selection of the most representative contributions, which are grouped under the following four themes: Part I Concepts and Knowledge - Part II Modelization - Part III Applied Evolutionary Biology - Part IV Applications in Other Fields -Part IV transcends the field of biology, presenting applications of evolutionary biology in economics and astronomy.
