This book provides an introduction to the significant role of physics in evolution, based on the ideas of matter and energy resource flow, organism self-copying, and ecological change. The text employs these ideas to create quantitative models for important evolutionary processes. Many fields of science and engineering have come up against the problem of complex design-when details become so numerous that computer power alone cannot make progress. Nature solved the complex-design problem using evolution, yet how it did so has been a mystery. Both laboratory experiments and computer-simulation attempts eventually stopped evolving. Something more than Darwin's ideas of heredity, variation, and selection was needed. The solution is that there is a fourth element to evolution: ecological change. When a new variation is selected, this can change the ecology, and the new ecology can create new opportunities for even more new variations to be selected. Through this endless cycle, complexity can grow automatically. This book uses the physics of resource flow to describe this process in detail, developing quantitative models for many evolutionary processes, including selection, multicellularity, coevolution, sexual reproduction, and the Serengeti Rules. The text demonstrates that these models are in conceptual agreement with numerous examples of biological phenomena, and reveals, through physics, how complex design can arise naturally. This will serve as a key text on the part physics plays in evolution, and will be of great interest to students at the university level and above studying biophysics, physics, systems biology, and related fields.
The Textbook of Ion Channels is a set of three volumes providing a wide-ranging reference source on ion channels for students, instructors, and researchers. Ion channels are membrane proteins that control the electrical properties of neurons and cardiac cells, mediate the detection and response to sensory stimuli like light, sound, odor, and taste, and regulate the response to physical stimuli like temperature and pressure. In non-excitable tissues, ion channels are instrumental for the regulation of basic salt balance that is critical for homeostasis. Ion channels are located at the surface membrane of cells, giving them the unique ability to communicate with the environment, as well as the membrane of intracellular organelles, allowing them to regulate internal homeostasis. Ion channels are fundamentally important for human health and diseases, and are important targets for pharmaceuticals in mental illness, heart disease, anesthesia, pain and other clinical applications. The modern methods used in their study are powerful and diverse, ranging from single ion-channel measurement techniques to models of ion channel diseases in animals, and human clinical trials for ion channel drugs. Volume I, Part 1 covers fundamental topics such as the basic principles of ion permeation and selectivity, voltage-dependent, ligand-dependent and mechano-dependent ion channel activation mechanisms, the mechanisms for ion channel desensitization and inactivation and basic ion channel pharmacology and inhibition. Volume I, Part 2 aims to offer a practical guide of cardinal methods for researching ion channels, including heterologous expression and voltage-clamp and patch-clamp electrophysiology, isolation of native currents using patch-clamp, modelling ion channel gating, structures and its dynamics, crystallography and cryo- electron microscopy, fluorescence and paramagnetic resonance spectroscopy methods and genetics approaches in model organisms. All three volumes give the reader an introduction to fundamental concepts needed to understand the mechanism of ion channels, a guide to the technical aspects of ion channel research, offer a modern guide to the properties of major ion channel families, and include coverage of key examples of regulatory, physiological, and disease roles for ion channels.
The Opioid System as the Brain's Interface between Cognition and Motivation, Volume 239, focuses on the opioid system as the interface between the brain's cognitive and motivational systems. As the opioid system is widely distributed through the brain, particularly in areas implicated in cognition (hippocampus, prefrontal cortex, claustrum, thalamus) and motivation (hypothalamus, amygdala, pontine nuclei, periaqueductal gray and medulla), this book provides chapters that address ongoing research on topics such as the Brain's cognitive system, the Brain's motivational system, Antidepressant prescription patterns, Antidepressant-like effects of opioid receptor modulators, the Behavioral effects of antidepressant and anxiolytic drugs, and more.
In this eye-opening chronicle of scientific research on the brain in the early Cold War era, the acclaimed historian Andreas Killen traces the complex circumstances surrounding the genesis of our present-day fascination with this organ. The 1950s were a transformative, even revolutionary decade in the history of brain science. Using new techniques for probing brain activity and function, researchers in neurosurgery, psychiatry, and psychology achieved dramatic breakthroughs in the treatment of illnesses like epilepsy and schizophrenia, as well as the understanding of such faculties as memory and perception. Memory was the site of particularly startling discoveries. As one researcher wrote to another in the middle of that decade, “Memory was the sleeping beauty of the brain—and now she is awake.” Collectively, these advances prefigured the emergence of the field of neuroscience at the end of the twentieth century. But the 1950s also marked the beginning of the Cold War and a period of transformative social change across Western society. These developments resulted in unease and paranoia. Mysterious new afflictions—none more mystifying than “brainwashing”—also appeared at this time. Faced with the discovery that, as one leading psychiatrist put it, “the human personality is not as stable as we often assume,” many researchers in the sciences of brain and behavior joined the effort to understand these conditions. They devised ingenious and sometimes transgressive experimental methods for studying and proposing countermeasures to the problem of Communist mind control. Some of these procedures took on a strange life of their own, escaping the confines of the research lab to become part of 1960s counterculture. Much later, in the early 2000s, they resurfaced in the War on Terror. These stories, often told separately, are brought together by the historian Andreas Killen in this chronicle of the brain’s mid-twentieth-century emergence as both a new research frontier and an organ whose integrity and capacities—especially that of memory—were imagined as uniquely imperiled in the 1950s. Nervous Systems explores the anxious context in which the mid-century sciences of the brain took shape and reveals the deeply ambivalent history that lies behind our contemporary understanding of this organ.

Have you ever wondered why psychologists still can't agree on what intelligence is? Or felt dismayed by debates around individual differences? Criticising the pitfalls of IQ testing, this book explains the true nature of intelligent systems, and their evolution from cells to brains to culture and human minds. Understanding Intelligence debunks many of the myths and misunderstandings surrounding intelligence. It takes a new look at the nature of the environment and the development of 'talent' and achievement. This brings fresh and radical implications for promoting intelligence and creativity, and prompts readers to reconsider their own possibilities and aspirations. Providing a broad context to the subject, the author also unmasks the ideological distortions of intelligence in racism and eugenics, and the suppressed expectations across social classes and genders. This book is a must-read for anyone curious about our own intelligence.
Epigenetic Principles of Evolution, Second Edition, fully examines the causal basis of evolution from an epigenetic point-of-view. By revealing the epigenetic uses of the genetic toolkit, this work demonstrates the primacy of epigenetic mechanisms and epigenetic information in generating evolutionary novelties. The author convincingly supports his theoretical perspective with examples from varied fields of biology, emphasizing changes in developmental pathways as the basic source of evolutionary change in metazoans. Users will find a broader view of the epigenetic mechanisms of evolution, moving beyond conventional changes in epigenetic structures, such as DNA methylation, histone modifications, and patterns of miRNA, sRNA, and mRNA expression. This second edition is thoroughly updated to reflect new evidence and developing theories in the field of evolutionary epigenetics. New and revised chapters speak to the epigenetic basis of heredity, epigenetic regulation of animal structure and homeostasis, neural manipulation of gene expression, central control of gametogenesis, epigenetic control of early development, the origin of epigenetic information, evolutionary changes in response to environmental stressors, epigenetics of sympatric evolution, and the epigenetics of the Cambrian explosion, among other topics.
Humans have changed ecosystems more rapidly and extensively in the
last 50 years than in any comparable period of human history. We
have done this to meet the growing demands for food, fresh water,
timber, fiber, and fuel. While changes to ecosystems have enhanced
the well-being of billions of people, they have also caused a
substantial and largely irreversible loss in diversity of life on
Earth, and have strained the capacity of ecosystems to continue
providing critical services.
Trees and woodlands are an integral part of Britains heritage and culture, as well as an invaluable environmental and ecological resource. In an increasingly urbanized British population, romantic notions of bluebell-carpeted woods and deep-coloured wooded hillsides during autumn do not come easily. Instead, images of forgotten corners of land with a few sycamore trees and lots of brambles, or an area of dark, intimidating conifers are more common. The wide variety of types of woodland, whether closely managed or naturally-occuring, provide important habitats for a huge range of flora and fauna. This text explores the history and ecology of British woodlands, and explains why they are such a valuable resource. It offers a practical guide to issues of ecology of woodland habitats and organisms; conservation and management; coppicing, pasture woodland and commercial forestry; woodland grazing, ride management and recration in woodlands. Featuring illustrated species boxes as well as a full species list, notable sites with location maps and pictures, suggested projects and a full glossary, students and environmentalists should gain an understanding of the historical and present-day im
