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.
In contemporary ethical discussion widespread concern about the potential risks of genetic engineering is raising new and fundamental questions about our responsibilities towards unborn generations.
Members of the family Littorinidae are among the most widely studied gastropod molluscs and the more questions we answer about this group, the more questions are inevitably posed.
Genetic Resources of Mediterranean Pasture and Forage Legumes is a comprehensive review of grassland improvement in Mediterranean areas using legume species.
A comprehensive account of genomic rearrangement, focusing on the mechanisms of inversion, translocation, gene and genome duplication and gene transfer and on the patterns that result from them in comparative maps.
During the last 50 years, the perception oftransposable elements (TEs) has changed considerably from selfish DNA to sequences that may contribute significantly to genome function and evolution.
It is a distressing truism that the human race during the last millennium has caused the exponential loss of plant genetic diversity throughout the world.
Tropical climates, which occur between 23(deg)30'N and S latitude (Jacob 1988), encompass a wide variety of plant communities (Hartshorn 1983, 1988), many of which are diverse in their woody floras.
In the summer of 1992 a distinguished group of molecular, population and evolutionary geneticists assembled on the campus of the University of Georgia in Athens, USA to discuss the relevance of their research to the role played by transposable elements (TEs) in evolution.
Our understanding of the mechanisms regulating gene expression, which determine the patterns of growth and development in all living organisms, ultimately involves the elucidation of the detailed and dy- namic interactions of proteins with nucleic acids -both DNA and RNA.
Developmental Instability: Its Origins and Evolutionary Implications is a collection of papers and transcribed discussions from a conference held in Tempe, Arizona in June 1993.
advanced metastatic disease of solid tumors, dictates that each tumor mass, indeed each individual metastasis, will have a unique antigen and cytokine environment and hence unique response to immune modu- lation.
Turbellaria, the mainly free-living flatworms, and some of their parasitic relatives, are among the simplest of the metazoa and, as such, provide ideal models for a wide range of fundamental studies.
During the decade since the publication of the first edition of this important book, there has been a rapid advancement in the techniques of genetic engineering and molecular biology.
Population genetics is the mathematical investigation of the changes in the genetic structure of populations brought about by selection, mutation, inbreeding, migration, and other phenomena, together with those random changes deriving from chance events.
It was at the end of the 19th century that a Swiss biologist, Karl Nageli first proposed the existence of hereditary organelles that carried information from parent to offspring.
Chromosome Painting is the most modern and novel technique for directly identifying several gene sequences simultaneously in the chromosome, with the aid of specific probes in molecular hybridization.
Advances in genetics, such as the Human Genome Project's successful mapping of the human genome and the discovery of ever more sites of disease-related mutations, invite re-examination of basic concepts underlying our fundamental social practices and institutions.
In the years since the publication of Susumu Ohno's 1970 landmark book Evolution by gene duplication tremendous advances have been made in molecular biology and especially in genomics.
Although interest in evolutionary novelties can be that these different mechanisms cooperate in the mak- traced back to the time of Darwin, the appreciation ing of new genes.
From guppies to Galapagos finches and from adaptive landscapes to haldanes, this compilation of contributed works provides reviews, perspectives, theoretical models, statistical developments, and empirical demonstrations exploring the tempo and mode of microevolution on contemporary to geological time scales.
