Barry Lopez

Book DescriptionIn this collection of twelve stories, Barry Lopez—the National Book Award–winning author of Arctic Dreams and one of our most admired writers—evokes the longing we feel for beauty in our relationships with one another, with the past, and with nature. An anthropologist traveling with an aboriginal people finds that, because of his aggressive desire to understand them, they remain always disturbingly unknowable. A successful financial consultant, failing to discover his roots in Africa, jogs from Connecticut to the Pacific Ocean in order to forge an indigenous connection to the American landscape. A paleontologist is haunted by visions of wildlife in a vacant lot in Manhattan. In simple, crystalline prose, Lopez evokes a sense of the magic and marvelous strangeness of the world, and a deep compassion for the human predicament.

The giant clam, Tridacna gigas, or traditionally, pa?ua, is the largest living bivalve mollusk. Tridacna gigas is one of the most endangered species amongst the clams. It was mentioned as early as 1825 in scientific reports.Giant Clam One of a number of large clam species native to the shallow coral reefs of the South Pacific and Indian oceans, they can weigh more than 200 kilograms (440 pounds), measure as much as 1.2 metres (4 feet) across, and have an average lifespan in the wild of 100 years or more. They are also found off the shores of the Philippines, where they are called taklobo. T. gigas lives in flat coral sand or broken coral and can be found at depth of as much as 20 meters. Its range covers the entire Indo-Pacific, but populations are diminishing quickly and the giant clam has become extinct in many areas where it was once common. T. maxima has the largest geographical distribution of the giant clam species; it can be found in high- or low-islands, lagoons, or fringing...

High Quality Content by WIKIPEDIA articles! Primary nutritional groups are groups of organisms, divided according to the sources of energy and carbon, needed for living, growth and reproduction. The sources of energy can be light and organic or inorganic compounds; the sources of carbon can be of organic or inorganic origine. The terms aerobic respiration, anaerobic respiration and fermentation do not refer to primary nutritional groups, but simply reflect the different use of possible electron acceptors in particular organisms, such as O2 in aerobic respiration, or NO3-, SO42- or fumarate in anaerobic respiration, or various metabolic intermediates in fermentation. Because all ATP-generating steps in fermentation involve modifications of metabolic intermediates instead of the use of an electron transport chain fermentation is often referred to as substrate-level phosphorylation.

"We must teach students the conceptual and technical approaches used to solve problems in biology. This book will do this superbly." – Professor Steve Oliver, School of Biological Sciences, University of Manchester, UK Molecular genetic analysis is the fusion of biochemical and genetic approaches to investigate the underlying mechanisms of cellular processes. These techniques have been developed over the past decades by researchers working with model organisms such as bacteriophage, E. coli, Saccharomyces, Drosophila, maize, and more recently, Arabidopsis and C. elegans. The details of cultivation and crossing of each organism differ, but the theory behind molecular genetic analysis is the same for all of these organisms. Genetic Techniques for Biological Research teaches the methods of molecular genetic analysis using a case study approach with the yeast Saccharomyces as the model genetic organism. The tools available for Saccharomyces are the most highly developed,...

A hammerhead shark slices through the warm waters of the Gulf of California and people splash toward the shore, frightened by Hammerhead's presence. Hammerhead is not intending to frighten anyone; she is heading for the shallow waters of the nearby reef t give birth. This text refers to an out of print or unavailable edition of this title.

Designed as both a textbook and reference, Molecular Epidemiology of Infectious Diseases: Principles and Practices outlines the principles, methods, and applications of this exciting new discipline of public health. Techniques utilized in the field of molecular biology have been recognized as critical tools in solving infectious disease problems. This introductory volume, distinguishing molecular epidemiology from taxonomy and phylogeny, will familiarize epidemiologists with molecular biology and molecular biologists with epidemiology and will present vocabulary and concepts of both fields to infectious disease clinicians. Molecular Epidemiology of Infectious Diseases provides a state–of–the–art review of molecularepidemiology, using real–world examples thatclearly illustrate basic concepts. While emphasisis placed on bacterial infectious diseases asthe discussion model, ideas presented are generallyapplicable to other categories of...

In the four decades since the discovery of DNA, molecular genetics and biotechnology have undergone a revolution in the research and application of genetic testing techniques. As a result, these fields have witnessed an explosion of both information and controversy, and the focus of public awareness of the significance of molecular biotechnology in everyday life has leaped from journal abstracts to front–page news. Molecular biotechnology provides important tools for the identification of specific nucleic acid sequences, some of them linked to important traits such as those conferring resistance to disease. Such DNA markers are used commonly in genetic research and in other applications, such as DNA fingerprinting. Researchers can use DNA markers to follow individual traits in different environments and hosts, increasing our understanding of the constitution, diversity, and evolution of genetic material. DNA Markers: Protocols, Applications, and Overviews offers valuable new...

Tom Wakeford

Advance Praise for Liaisons of Life "The complexity of life has forced on biologists a less detached approach than is usual in science. Their feeling for the organism conflicts with their dispassionate reduction of its DNA sequence. Tom Wakeford?s fine book movingly captures the consequence of this tension on scientists and politicians in his history of the concept of symbiosis. All scientists should read it."––James Lovelock, author of the Gaia Hypothesis "A thoroughly readable look at the history of one of biological science?s greatest ideas . . . Symbiosis is clearly an idea whose time has come, and Tom Wakeford helps us understand why."––Roger Knutson, author of Fearsome Fauna "Thanks to Tom Wakeford for his tales of life as a long adventure in partnership, and for his stories of people who pioneered that idea. With a true naturalist?s eye and a store of engaging anecdotes, he shows how the concept of symbiosis has moved from the fringe of science to its...

Human mitochondrial genetics is the study of the genetics of the DNA contained in human mitochondria. Mitochondria are small structures in cells that generate energy for the cell to use, and are hence referred to as the "powerhouses" of the cell. Mitochondrial DNA (mtDNA) is not transmitted through nuclear DNA (nDNA). In humans, as in most multicellular organisms, mitochondrial DNA is inherited only from the mother's ovum. The mitochondrial DNA inherited by a female from its mother's egg produces mitochondria to supply the energy to sustain the female's eggs. Mitochondrial inheritance is therefore non-Mendelian, as Mendelian inheritance presumes that half the genetic material of a fertilized egg (zygote) derives from each parent.
