Zebrafish has become a model organism for the study of developmental biology and genetics. Less is, however, known about the behaviour of this cyprinid fish. A zebrafish is exposed to many unfamiliar objects during its lifetime, and the response to these stimuli is critical for an adaptive behaviour. This book presents a master thesis from the University of Bergen in Norway on the behaviour of zebrafish of different origin and background towards a novel object and how the alarm pheromone released by this species upon predator attack modifies the response. In this study we found that laboratory fish inspected the novel object earlier, whereas the presence of a novel object and also alarm substance increased shoaling more in the wild strain. Overall,laboratory zebrafish were bolder than fish from the wild strain. This book provides valuable knowledge on how genetics and experience interact to shape the behaviour towards a potential threat in different strains of zebrafish. It is...

This first book to cover neural development, neuronal survival and function on the genetic level outlines promising approaches for novel therapeutic strategies in fighting neurodegenerative disorders, such as Alzheimer?s disease. Focusing on transcription factors, the text is clearly divided into three sections devoted to transcriptional control of neural development, brain function and transcriptional dysregulation induced neurological diseases. With a chapter written by Nobel laureate Eric Kandel, this is essential reading for neurobiologists, geneticists, biochemists, cell biologists, neurochemists and molecular biologists.

Who among us hasn’t marveled at the diversity and beauty of shells? Or picked one up, held it to our ear, and then gazed in wonder at its shape and hue? Many a lifelong shell collector has cut teeth (and toes) on the beaches of the Jersey Shore, the Outer Banks, or the coasts of Sanibel Island. Some have even dived to the depths of the ocean. But most of us are not familiar with the biological origin of shells, their role in explaining evolutionary history, and the incredible variety of forms in which they come. Shells are the external skeletons of mollusks, an ancient and diverse phylum of invertebrates that are in the earliest fossil record of multicellular life over 500 million years ago. There are over 100,000 kinds of recorded mollusks, and some estimate that there are over a million more that have yet to be discovered. Some breathe air, others live in fresh water, but most live in the ocean. They range in size from a grain of sand to a beach ball and in weight from a...

High Quality Content by WIKIPEDIA articles! In biochemistry, a receptor is a protein molecule, embedded in either the plasma membrane or the cytoplasm of a cell, to which a mobile balls signaling molecule may attach. A molecule which binds to a receptor is called a ligand, and may be a peptide or other small molecule, such as a neurotransmitter, a hormone, a pharmaceutical drug, or a toxin. When such binding occurs, the receptor undergoes a conformational change, which ordinarily initiates a cellular response. However, some ligands (e.g. antagonists) merely block receptors without inducing any response. Ligand-induced changes in receptors result in cellular changes which constitute the biological activity of the ligands.

Cl – absorption and HCO 3 – secretion are intimately associated processes vital to epithelial function, itself a key physiological activity. Until recently the transporters responsible remained obscure, but a breakthrough occurred with the discovery of the SLC26 transporters family. It is now clear that the SLC26 transporters have broad physiological functions since mutations in several members are linked to a variety of diseases. This book describes the properties of this family in detail, with contributions from the leading global researchers in the field. Complementary views from experts on other ion channels are offered in the discussions, which make fascinating reading. This family consists of at least 10 genes, each of which has several splice variants. Most members of the family are expressed in the luminal membrane of epithelial cells. Characterization of anion transport by three members has revealed that all function as Cl – ...

Human domination of the earth is now so complete that it is easy to forget how recently our role in the history of the planet began: the earliest apes evolved around twenty million years ago, yet Homo sapiens has existed for a mere 150,000 years. In the intervening period, many species of early ape and human have lived and died out, leaving behind the fossilized remains that have helped to make the detailed picture of our evolution revealed here. This exciting, up-to-the-minute account is divided into three accessible sections. "In Search of Our Ancestors" examines the contexts in which fossilized remains have been found and the techniques used to study them. "The Fossil Evidence" traces in detail the evolution of apes and humans, from Proconsul to the australopithecines, and Homo erectus to the Neanderthals and Homo sapiens. The latest fossil finds at major new sites such as Dmanisi in Georgia and Gran Dolina in Spain are appraised, and new advances in genetic studies,...

High Quality Content by WIKIPEDIA articles! In biochemistry and molecular biology, a residue refers to a specific monomer within the polymeric chain of a polysaccharide, protein or nucleic acid. For example, one might say, "The histidine residue is considered to be basic due to its imidazole ring." Note that a residue is different from a moiety, which, in the above example would be constituted by the imidazole ring or "the imidazole moiety". Note the origin of this usage: during the process by which monomeric building blocks (e.g. amino acids) are strung together into a polymeric chain (e.g. a protein), some material (typically adding up to one molecule of water) is discarded from each building block, and only a "residue" of the building block ends up in the finished product. For example, a residue is an individual amino acid in a peptide chain.

Greg Skomal

Greg Skomal is one of the world’s leading shark experts: many thousands of viewers know him as the "Shark Guy" on Discovery Channel and he’s affiliated with the Woods Hole Oceanographic Institute. So if you’re dreaming of swimming with sharks, there’s no one better to take you - and that’s exactly what he does in this comprehensive, stunning field guide. In addition to an awesome gatefold poster of a Great White (with all its distinguishing features shown in detail), plus amazing original images from Skomal and award-winning National Geographic photographer Nick Caloyianis, it contains a complete listing of every known shark in existence as well as some extinct species. Learn about sharks from their birth to death, their anatomy, how to distinguish one shark from the next, how their teeth are developed, how they hunt and attack, and their importance and purpose within our eco system.
