  • STRUCTURE AND EVOLUTION OF STARS, THE
    Christopher A Tout / ELDRIDGE J J / J J Eldridge / J J ELDRIDGE & CHRISTOPHER A TOUT
    Stars are the fundamental observable constituents of the Universe. They are the first objects we see in the night sky, they dominate the light produced in our own and other galaxies, and nucleosynthesis in stars produces all the elements heavier than helium. A knowledge of stars and their evolution is vital to understand other astrophysical objects from accreting black holes an...

  • Ecological Homeostasis
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    Individual organisms contribute to nutrient cycling in ecological systems, which is shown to be a mechanism of homeostasis at that level. The phosphorus and nitrogen cycles are used to illustrate effects of changes in populations or communities on the cycling of these nutrients. Major disturbances such as deforestation and global climate change disrupt nutrient cycles and ecolo...

  • Emergent Properties of Individual Organisms
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    This book begins by describing what an individual organism is, comparing preconceptions of the individual to non-standard ways of thinking about individuals. Variation in what individuals are is described, using giant fungi, clonal trees and honey bee hives as examples. Individuals are thus shown to be emergent properties. Other emergent properties of individuals are also descr...

  • Population Homeostasis
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    This book will synthesize the concepts of selection against individuals in response to environmental change to illustrate how selection against individuals results in homeostasis at the population level. For instance, selection against the light phenotype of the peppered moth during the early part of the industrial revolution led to an increase of the dark phenotype, which was ...

  • Properties in and of Populations
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    Properties of populations include age and spatial distribution, both of which emerge from actions and properties of individuals and can affect population dynamics, the changes in populations and metapopulations over time and space. The age structure of a population is described and analyzed to determine how it affects the growth of a population. The various aspects of spatial s...

  • Neurons and Muscles
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    Whenever a dancer or an athlete performs amazing feats, it is the consequence of two very interesting cell types: neurons and muscles. When the two of these cell types work together, animals can move in complex ways with surprising control. Not only do they work together to produce movement, they have many traits in common. They both convert chemical signals into electrical inf...

  • Plant Physiology
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    This book examines three ways plants respond to their changing environment. The first example can be found in all plants. Despite the extreme changes in weather, plants have to stay where they are and respond to whatever nature produces. Plants have the capacity to respond quickly and yet they can evolve in a single generation. The second example addresses how an individual lea...

  • Molecular Structure and Function
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    One of the overarching themes in nature is that form meets function, meaning that the shape of an object determines how well the object can perform its function. This book begins with some basics about specificity of shapes and the four increasing levels of protein structure. Most of this book examines how epinephrine (adrenaline) can cause the liver to release glucose when a p...

  • Photosynthesis
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    Perhaps the most important chemical reactions on the planet take place inside a plant’s chloroplasts. In this tiny green organelle, plants have the capacity to capture the energy in light and use that energy to convert CO2 gas into building blocks used to produce all four categories of biological molecules-lipids, carbohydrates, proteins and nucleic acids. Animals could not sur...

  • Reproduction and Cell Division
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    Why do some children look more like one parent than another? How can two parents with dark hair have a child with red hair? How can two dark-skinned parents have a baby that has light skin? Everyone has wondered these questions, but in order to understand such unexpected outcomes, an understanding of what Gregor Mendel discovered-the rules of genetics-is necessary. This book re...

  • The Source of Genetic Information
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    Everyone who has taken any biology class knows that DNA is the heritable material. However, very few people know the evidence that led to this conclusion. Science is a discipline based on evidence not acceptance based on faith in a teacher or other authority. This book presents the historical and scientific context to understand how we know DNA is the heritable material. Furthe...

  • Evolution and Origin of Cells
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    It is easy to understand how cells are produced from preexisting cells. And it is possible to imagine how space dust condensed to form inanimate planets. But what stumps most people is how inanimate matter suddenly formed the first living cell. This problem has vexed scientists and philosophers over the millennia, but recent research has cracked open this black box that is the ...

  • Molecular Switches
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    This book introduces the concept of emergent properties, which are unexpected traits found only when two or more biological components interact. Experimental evidence of several emergent properties explains how hemoglobin can act like a high affinity oxygen carrier some times and then switch to a low affinity carrier exactly when and where it should. The second example presents...

  • Cell Networks
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    It is common for most people to mistakenly think that humans are the only species that can coordinate their behavior and build structures that protect them from the environment. Students of nature will think of birds building nests, but very few people know that bacteria are able to communicate and restructure their environment in complex ways that improve their ability to surv...

  • Evolution of Eukaryotes
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    Many people have a vague sense that the hypothesized origin of life, in the form of bacteria, sounds plausible. However, few people can fathom how the first eukaryotic cell, complete with nucleus, mitochondria and maybe chloroplast, came into being. This book presents the evidence that reveals the origins of all three DNA-containing organelles. In addition, this book will illus...

  • Using DNA Information to Make Proteins
    A. Malcolm Campbell / AMalcolm Campbell / Christopher J. Paradise / Christopher JParadise
    Many people were taught that DNA is the 'blueprint of the cell,' but what does that really mean? If taken literally, it would reveal a static image of what the cell looks like, but that would be incorrect. DNA codes the necessary information to produce a living being but the DNA itself is insufficient to bring a cell to life. DNA must be transcribed into segments of RNA and the...
