This book covers the natural history of the roe deer, describing its biology, reproduction and behaviour in layman's terms. Conservation topics include the impact of man on deer, problems raised by over-population and damage to forestry and farming.

Este texto persigue una comprensión del sistema microbio-medio que pueda servir de base para abordar cualquier otro aspecto del desarrollo microbiano, partiendo de unos conocimientos directamente comprobables que estructuran una teoría de los microbios en cultivo puro. Como puede verse siguiendo el índice de este libro, esta teoría comprendería la cinética del crecimiento de la biomasa microbiana, la generación de productos en el medio y la intervención de oxidantes y reductores presentes en el mismo incluyendo la utilización de los compuestos C1 y la utilización y producción de energía radiante.

The computational education of biologists is changing to prepare students for facing the complex datasets of today's life science research. In this concise textbook, the authors' fresh pedagogical approaches lead biology students from first principles towards computational thinking. A team of renowned bioinformaticians take innovative routes to introduce computational ideas in the context of real biological problems. Intuitive explanations promote deep understanding, using little mathematical formalism. Self-contained chapters show how computational procedures are developed and applied to central topics in bioinformatics and genomics, such as the genetic basis of disease, genome evolution or the tree of life concept. Using bioinformatic resources requires a basic understanding of what bioinformatics is and what it can do. Rather than just presenting tools, the authors - each a leading scientist - engage the students' problem-solving skills, preparing them to meet the computational challenges of their life science careers.

Obra muy novedosa por su planteamiento integral y diseño escrita pensando en las necesidades del alumno. En ella se recogen, de forma conjunta y concisa, los conceptos básicos de la biología molecular e ingenieria genetica, para, posteriormente, establecer sobre estas bases sus cada vez mayores aplicaciones tecnologicas y la terapeutica del futuro. Destaca la integracion de la informacion y el enfoque grafico-visual seguido en la exposicion de la misma, con predominio de esquemas y figuras sobre texto escrito; no hay que leer como es la hibridacion de los acidos nucleicos, hay que verlo. Para facilitar esta ¿explicacion visual¿, todo el libro es a cuatro colores, con un diseño atractivo y didactico y unas figuras espectaculares que se complementan con una serie de preguntas y ejercicios planteados al final de cada tema.

Barry Halliwell, John Gutteridge Halliwell (medical biochemistry, King's College, London) and Gutteridge (pharmacology, King's College) direct their discussion primarily to biologists and clinicians, and assume virtually no knowledge of chemistry. Their goal is to lead readers gently into an understanding of what free radicals are, how they are generated, and how they can react. Then they evaluate the role of radical reactions in several biological systems. The first edition appeared in 1985, and the 1989 second edition is here updated with the extensive information provided by modern techniques of molecular, cellular, and structural biology. They also cite at least one reference for each finding. Oxygen is a toxic gas - an introduction to oxygen toxicity and reactive species p. 1 The chemistry of free radicals and related 'reactive species' p. 30 Antioxidant defences : endogenous and diet derived p. 79 Cellular responses to oxidative stress : adaptation, damage, repair, senescence and death p. 187 Measurement of reactive species p. 268 Reactive species can pose special problems needing special solutions : some examples p. 341 Reactive species can be useful : some more examples p. 395 Reactive species can be poisonous : their role in toxicology p. 440 Reactive species and disease : fact, fiction or filibuster? p. 488 Ageing, nutrition, disease and therapy : a role for antioxidants? p. 614 Some basic chemistry p. 678 Table of Contents provided by Blackwell.

Davis, JohnValuable to both newcomers and experienced researchers. Fully revised and updated. Demonstrates techniques of great importance in biotechnology. Provides a grounding to more advanced texts in the Practical Approach Series. This book is a guide for the newcomer to all those areas which are currently basic to the performance of animal (including human) cell culture. Experienced workers should also find it useful as a source of reference when entering a new field, or when setting up a new laboratory.

Genomes 4 has been completely revised and updated. It is a thoroughly modern textbook about genomes and how they are investigated. As with Genomes 3, techniques come first, then genome anatomies, followed by genome function, and finally genome evolution. The genomes of all types of organism are covered: viruses, bacteria, fungi, plants, and animals including humans and other hominids. Genome sequencing and assembly methods have been thoroughly revised including a survey of four genome projects: human, Neanderthal, giant panda, and barley. Coverage of genome annotation emphasizes genome-wide RNA mapping, with CRISPR-Cas 9 and GWAS methods of determining gene function covered. The knowledge gained from these techniques forms the basis of the three chapters that describe the three main types of genomes: eukaryotic, prokaryotic (including eukaryotic organelles), and viral (including mobile genetic elements). Coverage of genome expression and replication is truly genomic, concentrating on the genome-wide implications of DNA packaging, epigenome modifications, DNA-binding proteins, non-coding RNAs, regulatory genome sequences, and protein-protein interactions. Also included are applications of transcriptome analysis, metabolomics, and systems biology. The final chapter is on genome evolution, focusing on the evolution of the epigenome, using genomics to study human evolution, and using population genomics to advance plant breeding. Established methods of molecular biology are included if they are still relevant today and there is always an explanation as to why the method is still important. Each chapter has a set of short-answer questions, in-depth problems, and annotated further reading. There is also an extensive glossary. Genomes 4 is the ideal text for upper level courses focused on genomes and genomics.

Dentro de la amplia gama de disciplinas que constituyen la ciencia básica, la genética se ha desarrollado de manera impresionante en los últimos años, lo que ha generado una gran cantidad de informacion. Esta cuarta edicion de Principios de Genetica analiza los avances mas recientes en muchas areas de la genetica -clasica, molecular y de poblaciones- y presenta en una secuencia clara y logica los fundamentos de esta ciencia. En comparacion con las ediciones anteriores, esta se ha ampliado y reorganizado considerablemente.

Twenty inorganic elements, mostly metal ions, are consistently found in living systems and are essential for living systems to function correctly. The aim of this text is to discuss, describe, and explain the functional relevance of those elements: the reasons for their selection; the processes of their uptake, transport and final localization in cells; the regulation of these processes; and the interactive network of their reactions that connects the in vivo inorganic elements to the environment and to the genome. The first seven chapters describe the physical, chemical, and biological principles of the involvement of the elements in cellular activity, stressing how inorganic and organic chemicals react differently together in different compartments. The next twelve chapters describe the uses of the individual essential inorganic elements and a section on the genetic control of each element is included. The final chapter discusses how the interaction of genes, proteins, small molecules, and inorganic elements plays an important role in evolution and the speciation of organisms.The second edition of 'The Biological Chemistry of The Elements' has been thoroughly revised in content and style. The main additions to the first edition concern the discussion of the links to the genome of the uptake and transfer of inorganic elements and the regulation of homeostasis, the functional co-operative activities of the elements, the interaction with the environment, and the evolution of usage. Recent structural and mechanistic knowledge of many biomolecules and organelles are also included. Like the higly praised first edition, this text will be the bible of bioinorganic chemistry.
