More than two third of the surface area of our planet is covered by oceans and assessment of the marine biodiversity is a challenging task. With the increasing global population, there is a tendency to exploit marine recourses for food, energy and other requirements. This puts pressure on the fragile marine environment and needs sustainable conservation efforts. Marine species identification using traditional taxonomical methods are often burdened with taxonomic controversies. Here in this book we will discuss the comparatively new concept of DNA barcoding and its significance in marine perspective. This molecular technique can be helpful in the assessment of cryptic species which are widespread in marine environment, and can also be used to link the different life cycle stages to the adult which is difficult to accomplish in marine ecosystems. Other advantages of DNA barcoding include authentication and safety assessment of seafood, wildlife forensics, conservation genetics and detection of invasive alien species (IAS). Global DNA barcoding efforts in the marine habitat include MarBOL, CeDAMar, CMarZ, SHARK-BOL, etc. DNA barcoding of different marine groups ranging from the microbes to mammals is to be revealed. In conjugation with newer and faster techniques like high throughput sequencing, DNA barcoding is serving as an effective modern tool in marine biodiversity assessment and conservation.
The book combines information about the behaviour that allowed ruminants to survive and to evolve on Earth: the rumen. Furthermore, the reader will find aspects involving rumen anatomy, physiology, microbiology, fermentation, metabolism, manipulation, kinetics and modeling. Thus, the book was not only organized to help students involved in areas such as ruminant nutrition and ruminant production but collegians gathering material for teaching practices.
This book presents 19 selected contributions to the 20th Evolutionary Biology Meeting in Marseille, which took place in September 2016. They are grouped under the following major themes: * Self/Nonself Evolution * Species Evolution and Evolution of Complex Traits * Methods and Concepts The aims of the annual meetings in Marseille - which bring together leading evolutionary biologists and other scientists using evolutionary biology concepts, e.g. for medical research - are to promote the exchange of ideas and to encourage interdisciplinary collaborations. Offering a revealing overview of the latest findings in the field of evolutionary biology, this book represents an invaluable source of information for scientists, teachers and advanced students alike.
This book describes the discovery of molecules from unexploited extreme marine environments, and presents new approaches in marine genomics. It combines the current state of knowledge in marine genomics and advanced natural products' chemistry to pursue the sustainable production of novel secondary metabolites (lead compounds), as well as pharmacologically active peptides/proteins, with antimicrobial, neuroprotective, anti-osteoporotic, anti-protozoan/anti-plasmodial, anti-ageing and immune-modulating effects. Further, it employs molecular-biology-based approaches and advanced chemical techniques to obtain and to select candidate compounds for pre-clinical and clinical studies.
The foundation of quantitative genetics theory was developed during the last century and facilitated many successful breeding programs for cultivated plants and t- restrial livestock. The results have been almost universally impressive, and today nearly all agricultural production utilises genetically improved seed and animals. The aquaculture industry can learn a great deal from these experiences, because the basic theory behind selective breeding is the same for all species. The ?rst published selection experiments in aquaculture started in 1920 s to improve disease resistance in ?sh, but it was not before the 1970 s that the ?rst family based breeding program was initiated for Atlantic salmon in Norway by AKVAFORSK. Unfortunately, the subsequent implementation of selective breeding on a wider scale in aquaculture has been slow, and despite the dramatic gains that have been demonstrated in a number of species, less than 10% of world aquaculture production is currently based on improved stocks. For the long-term sustainability of aquaculture production, there is an urgent need to develop and implement e- cient breeding programs for all species under commercial production. The ability for aquaculture to successfully meet the demands of an ever increasing human p- ulation, will rely on genetically improved stocks that utilise feed, water and land resources in an ef?cient way. Technological advances like genome sequences of aquaculture species, and advanced molecular methods means that there are new and exciting prospects for building on these well-established methods into the future.
This publication contains the proceedings of a seminar held in Brussels on November 8-9, 1988. The title of the seminar was "Reducing the costs of disease by improving resistance through genetics." The seminar was held as an activity of the Community Programme for the Coordination of Agricultural Research, 1984-1988. Costs of disease depend on losses caused by morbidity, mortality and production decreases and on the costs of preventive measures including vaccination and medication. Production losses often contribute a major portion to the total costs. To reduce costs of disease preventive measures like vaccination, preventive medication and hygienic procedures are applied. Genetic resistance is an attractive preventive measure because of its consistent nature in the next generations, because it precludes veterinary services and because there are no side-effects. Constraints are the long term investment, relatively slow progress per generation (in combination with production traits) and the considerable lack of knowledge about inheritance of resistance mechanisms in farm animals.
This book fills the gap between textbooks of quantitative genetic theory, and software manuals that provide details on analytical methods but little context or perspective on which methods may be most appropriate for a particular application. Accordingly this book is composed of two sections. The first section (Chapters 1 to 8) covers topics of classical phenotypic data analysis for prediction of breeding values in animal and plant breeding programs. In the second section (Chapters 9 to 13) we provide the concept and overall review of available tools for using DNA markers for predictions of genetic merits in breeding populations. With advances in DNA sequencing technologies, genomic data, especially single nucleotide polymorphism (SNP) markers, have become available for animal and plant breeding programs in recent years. Analysis of DNA markers for prediction of genetic merit is a relatively new and active research area. The algorithms and software to implement these algorithms are changing rapidly. This section represents state-of-the-art knowledge on the tools and technologies available for genetic analysis of plants and animals. However, readers should be aware that the methods or statistical packages covered here may not be available or they might be out of date in a few years. Ultimately the book is intended for professional breeders interested in utilizing these tools and approaches in their breeding programs. Lastly, we anticipate the usage of this volume for advanced level graduate courses in agricultural and breeding courses.

Mercury is widespread in our environment. Methylmercury, an organic form of mercury, can accumulate in the aquatic food chain and lead to high concentrations in predatory fish. When consumed by humans, contaminated fish represent a public health risk. Toxic Effects of Mercury intends to facilitate among its readers the understanding of the importance of mercury pollution in the environment and the health consequences associated with exposure to this metal. The knowledge on methylmercury (MeHg) toxicity collected over the years is undoubtedly robust creating an impression all that is to be learnt about this metal has already been accomplished. However, in large measure, past knowledge has merely laid the ground for interesting questions that have yet to be fully addressed and concepts have yet to be deciphered. One of my major goals was to make a valiant attempt to include state-of-the-art information on the mechanisms of mercury toxicity, describing its effects on cultured cellular systems as well as in whole living organisms, starting from the lessons learned from the tragic events in Minamata Bay, Japan. A special focus of the book is on the neurotoxic effects of MeHg. An understanding at the cellular level is necessary to gather information on the structural and functional alterations induced by MeHg and how they possibly become unmasked and evident at the behavioral level, 32 chapters of the book have been organised having these considerations in mind. This book will provide state-of-the-art information to the graduate students training in toxicology, risk assessors, researchers and medical providers at large. It is aimed to bring the readers updated information on contemporary issues associated with exposure to methylmercury, from its effects on stem cells and neurons to population studies. It is a valuable resource for individuals interested in the public health effects and regulation of mercury. The report provides an excellent example of the implications of decisions in the risk assessment process for a larger audience and is written with the hope that the information will provide better understanding of the mercury problems which confront us.
Not so long ago, karyology was considered a vanguard biological discipline, which could solve nearly all problems of systematics and phylogenetics. We liked to believe in the bright future, in a magician who will appear like a Jack-in-the-box and reveal the truth to us. However, excessive hopes related to the chromosomal study came true only in part. In the meantime, new candidates claimed the place of the magician, i. e. phenetics succeeded by cladistics and now by molecular methods in systematics and phylogeny. Nevertheless, it becomes progressively more ob- ous nowadays that cladistics is just a bright envelope for the fairly primitive and theoretically vulnerable approach that deprives living organisms and their groups of the traces of integrity and reduces them to the plain sum of characters. Modern molecular techniques look more perceptive and may yield more reliable results, although the details are sometimes embarrassing, and comparison with the fossil record does not necessarily reveal their superiority over cladistics. These methods are accessible by research teams with massive funding and good equipment and this strongly decreases the range and diversity of the material studied. However, classi?cations are often created by individual systematists with the restricted access to molecular methods. In this context, karyological techniques are in the preferable position, although they certainly do not provide direct and immaculate markers of taxonomic and p- logenetic relationships: chromosomal study is a morphological method with all its advantages and drawbacks.
Mapping of animal genomes has generated huge databases and several new concepts and strategies, which are useful to elucidate origin, evolution and phylogeny. Genetic and physical maps of genomes further provide precise details on chromosomal location, function, expression and regulation of academically and economically important genes. The series Genome Mapping and Genomics in Animals provides comprehensive and up-to-date reviews on genomic research on a large variety of selected animal systems, contributed by leading scientists from around the world. Laboratory animals are those species that by accident of evolution, domestication and selective breeding are amenable to maintenance and study in a laboratory environment. Many of these species are studied as 'models' for the biology and pathology of humans. Laboratory animals included in this volume are sea-urchin, nematode worm, fruit fly, sea squirts, puffer fishes, medaka fish, African clawed frog, mouse and rat.
After having read this book you will never see birds in the same way again. The unexpected patterns displayed by a bird's body have been seen as bizarre events that demanded little attention or were described as 'amazing curiosities'. None of these surprising features seem to be fortuitous. They appear to be an integral part of a rigid order and a coherent geometry, which is directed by simple gene interactions and molecular cascades occurring at various cellular levels, and at different times, during the organism's development. A novel geometry unfolds in front of your eyes, giving the body configurations another meaning. Lima-de-Faria is Professor Emeritus of Molecular Cytogenetics at Lund University, Lund, Sweden. This is his sixth book dealing with the molecular organization of the chromosome and its implications for the understanding of the mechanisms responsible for biological evolution.
