Download or read book A New Paradigm for the Conquest of Land by Vertebrates That Includes Exaptations written by Mauro Luís Triques and published by BRILL. This book was released on 2024-04-02 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new view for studying and understanding biological evolution emerges when the concepts of phylogenetic systematics and exaptation are combined. A new definition of macroevolution is created. Preadaptation is shown to be a null concept and its comparison with exaptation is shown to be inappropriate. This book criticizes the prevailing view, the adaptationist, microevolutionary outlook, which considers adaptation as being the exclusive or main evolutionary process responsible for vertebrates having occupied the terrestrial environment. The authors argue that the macroevolutionary processes are significantly more important to explain an improbable evolutionary event. Their research shows that macroevolutionary processes are the dominant factors involved in the origin of terrestriality. This book is a revised and expanded English translation from the original Portuguese edition Peixes conquistam a terra firme: nova abordagem para um evento acidental único (Editora Baraúna, 2017).

Available in PDF, EPUB and Kindle. Book excerpt: Take your knowledge of fishes to the next level Fishes of the World, Fifth Edition is the only modern, phylogenetically based classification of the world’s fishes. The updated text offers new phylogenetic diagrams that clarify the relationships among fish groups, as well as cutting-edge global knowledge that brings this classic reference up to date. With this resource, you can classify orders, families, and genera of fishes, understand the connections among fish groups, organize fishes in their evolutionary context, and imagine new areas of research. To further assist your work, this text provides representative drawings, many of them new, for most families of fishes, allowing you to make visual connections to the information as you read. It also contains many references to the classical as well as the most up-to-date literature on fish relationships, based on both morphology and molecular biology. The study of fishes is one that certainly requires dedication—and access to reliable, accurate information. With more than 30,000 known species of sharks, rays, and bony fishes, both lobe-finned and ray-finned, you will need to master your area of study with the assistance of the best reference materials available. This text will help you bring your knowledge of fishes to the next level. Explore the anatomical characteristics, distribution, common and scientific names, and phylogenetic relationships of fishes Access biological and anatomical information on more than 515 families of living fishes Better appreciate the complexities and controversies behind the modern view of fish relationships Refer to an extensive bibliography, which points you in the direction of additional, valuable, and up-to-date information, much of it published within the last few years Fishes of the World, Fifth Edition is an invaluable resource for professional ichthyologists, aquatic ecologists, marine biologists, fish breeders, aquaculturists, and conservationists.

Book excerpt: A detailed guide of everything you want and need to know about fish. A fish is a water-dwelling vertebrate with gills that doesn''t change form, as amphibians do, during its life. Most are cold-blooded, though some (such as some species of tuna and shark) are warm-blooded. There are over 29,000 species of fish, making them the most diverse group of vertebrates. Fishing is the activity of hunting for fish. Fishing is a very ancient practice that dates back at least to the Mesolithic period which began about 10,000 years ago. Fishing is the activity of hunting for fish. By extension, the term fishing is also applied to hunting for other aquatic animals such as various types of shellfish as well as squid, octopus, turtles, frogs and some edible marine invertebrates. Fish as a food describes the edible parts of water-dwelling, cold-blooded vertebrates with gills, as well as certain other water-dwelling animals such as mollusks, crustaceans, and shellfish. An aquarium (plural aquariums or aquaria) is a vivarium, usually contained in a clear-sided container (typically constructed of glass or high-strength plastic) in which water-dwelling plants and animals (usually fish, and sometimes invertebrates, as well as amphibians, marine mammals, and reptiles) are kept in captivity, often for public display; or it is an establishment featuring such displays. A detailed guide of everything you want and need to know about fish.

This book was released on 2003-01-01 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fishery sector is important from Indian economy view point as it contributes a source of income to a number of fishermen and has huge export potential. The systems and technology used in aquaculture has developed rapidly in the last fifty years. They vary from very simple facilities like family ponds for domestic consumption in tropical countries to high technology systems like intensive closed systems for export production. Much of the technology used in aquaculture is relatively simple, often based on small modifications that improve the growth and survival rates of the target species. Nowadays, the fish and fisheries industry is one of the fastest growing international commodity markets globally. Guaranteeing an adequate supply to this international market requires hundreds of thousands of fishing vessels and fish farms, as well as tens of thousands of fish processing workers, wholesalers and retailers in countries spread all over the world. The fishery sector thus generates employment and income for millions of people and in one of the major fields to venture. A wide range of aspects of fresh water aquaculture such as selection of species of fish and shellfish, construction and preparation of various types of fish ponds, control of aquatic weeds and predators, production of seed fish and their transportation, fish nutrition and fish diseases and their control pertaining to composite fish culture, air breathing fish culture etc. have been dealt with a length for easy adoption. The major contents of the book are classification of fishes, general characters of fishes, techniques in fish identification, cold water fisheries of India, physical and chemical properties of fishery water, chemical constituents of fish, economic importance of fishes, fish in relation to human health, construction of fish farms, etc. In this book you can find all the basic information required on the fundamental aspects of the fisheries and aquaculture technology with detailed information of their applications a wide variety of industrial processes etc. The book is very useful for research scholars, technocrats, institutional libraries and entrepreneurs who want to enter into the field of aquaculture technology.
Download or read book Major Histocompatibility Complex written by M. Kasahara and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every biological system is the outcome of evolution and has a history all its own. This history dictates how the system works and why it has certain properties and not others. This is why we need to study not only the structure and function, but also the history of the system. This argument undoubtedly applies to the study of the immune system and also to the study of the major histocompatibility complex (MHC). Since 1989, researchers of various scientific disciplines who share a deep inter est in MHC evolution have held a meeting every two years to discuss their latest research developments, exchange ideas, and foster friendship. Together with my colleagues Drs. Naoyuki Takahata and Yoko Satta, I organized the Sixth Interna tional Workshop on MHC Evolution in Hayama, Japan, May 25-29, 1999. This volume is the proceedings of that conference. It covers diverse topics pertinent to MHC evolution, including the origin of the adaptive immune system, the organi zation of the MHC in humans and other model vertebrates, MHC-parasite co evolution, and the nature and origin of MHC polymorphism. I hope that this book will be of interest not only for MHC researchers and immunologists, but also for other specialists who are interested in the evolution of biological systems in gen eral.
