Book Description
It is not often that one has the opportunity to send a public birthday greet ing to a friend and colleague of many years, and to congratulate him on having reached the age of reason. In fact it happens only once, and comes then as a surprise. Surely it was only a few years ago that we sat together at an International Genetics Congress in Ithaca, and only yesterday that we became members of the same department. The eighth floor of Schermerhorn Hall had a north end where the flies were and a south end furnished with mice, and in between, a seminar room and laboratory. There the distances were short and the doors open and the coffee pot busy. But it now appears that yesterday has fallen thirty years behind and that we have grown up. I find it interesting and appropriate that Dobzhansky's lifetime spans the period of maturation of the fields to which this volume is devoted. This is true in a chronological sense for his birth occurred in the same year, 1900, in which modern genetics began. The rediscovery of Mendel's princi ples and the interpretation of the nature of heredity and variation to which this event led were necessary prerequisites to the development of evolution ary biology as presented in this collection of essays.

Book Description
Traditionally, studies in ecological genetics have involved both field observations and laboratory genetic analyses. Comparisons and cor relations between these two kinds of data have provided valuable in formation on the genetic strategies behind the evolutionary adapta tions of species and their component local populations. Indeed, much of our current understanding of the dynamics of evolutionary pro cesses has come fro~ syntheses of ecological and genetic information. Since the recent discovery of abundant markers in the form of protein polymorphisms, scientific interest in the connections between genetics and ecology has quickened considerably. This volume contains the proceedings of the Society for the Study of Evolution's symposium, Genetics and Ecology: The Interface, held at Ithaca College, Ithaca, New York, June 12-15, 1977. This particular topic was selected because of a general feeling that a significant integration of genetics and ecology has developed in the last decade or so. Host ecologists no longer believe that each species has a characteristic and constant birth, death, and develonment rate, habitat preference, and so on, but that these para~eters vary a~ong populations and are at least partially under genetic control and sub ject to natural selection. Similarly, few population geneticists still view any species as infinitely large, panmictic, constant in numbers, and distributed evenly throughout its range.

Book Description
This book focuses on drosophila as an especially useful model organism for exploring questions of evolutionary biology in the full range of evolutionary studies: population genetics, ecology, ecological genetics, speciation, phylogenetics, genome evolution, molecular evolution, and development. The author presents an integrated view of evolutionary biology as elucidated in this single organism. Special effort is made to point out holes in our knowledge and areas particularly ripe for new investigation.

Book Description
This book presents 20 selected contributions to the 18th Evolutionary Biology Meeting, which took place in September 2014 in Marseille. They are grouped under the following major themes: · Genotype to Phenotype · Genetic Mechanisms of Diversification · Evolutionary Mechanisms · Speciation and Biodiversity The aims of these annual meetings in Marseille are to bring together leading evolutionary biologists and other scientists who employ evolutionary biology concepts, e.g. for medical research, and to promote the exchange of ideas and encourage interdisciplinary collaborations. Offering an up-to-date overview of recent advances in the field of evolutionary biology, this book represents an invaluable source of information for scientists, teachers and advanced students.

Book Description
Latest figures suggest that approximately 20% of the world's population of six billion is malnourished because of food shortages and inadequate distrib ution systems. To make matters worse, it is estimated that some 75 billion metric tons of soil are removed annually from the land by wind and soil ero sion, much of it from agricultural land, which is thereby rendered unsuitable for agricultural purposes. Moreover, out of a total land area under cultivation 9 6 of approximately 1. 5 x 10 ha, some 12 x 10 ha of arable land are destroyed and abandoned worldwide each year because of unsustainable agricultural practices. Add to this the fact that the world population is increasing at the rate of a quarter of a million per day, and the enormity of the task ahead becomes apparent. To quote the eminent wheat breeder E. R. Sears, It seems clear that plant geneticists can look forward to an expanded role in the 21st century, particularly in relation to plant improvement. The suc cess of these efforts may go a long way towards determining whether the world's increasing billions of humans will be adequately fed. Food for an ever-increasing population will have to be produced not only from an ever-diminishing, but from what will become an ever-deteriorating land resource unless justifiable environmental concerns are taken into account.

Book Description
In science, more than elsewhere, a word is expected to mean what it says, nothing more, nothing less. But scientific discourse is neither different nor separable from ordinary language--meanings are multiple, ambiguities ubiquitous. Keywords in Evolutionary Biology grapples with this problem in a field especially prone to the confusion engendered by semantic imprecision. Written by historians, philosophers, and biologists--including, among others, Stephen Jay Gould, Diane Paul, John Beatty, Robert Richards, Richard Lewontin, David Sloan Wilson, Peter Bowler, and Richard Dawkins--these essays identify and explicate those terms in evolutionary biology which, though commonly used, are plagues by multiple concurrent and historically varying meanings. By clarifying these terms in their many guises, the editors Evelyn Fox Keller and Elisabeth Lloyd hope to focus attention on major scholarly problems in the field--problems sometimes obscured, sometimes reveals, and sometimes even created by the use of such equivocal words. "Competition," "adaptation," and "fitness," for instance, are among the terms whose multiple meaning have led to more than merely semantic debates in evolutionary biology. Exploring the complexity of keywords and clarifying their role in prominent issues in the field, this book will prove invaluable to scientists and philosophers trying to come to terms with evolutionary theory; it will also serve as a useful guide to future research into the way in which scientific language works.
