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.
This book has arisen from the Second European Meeting on Bacterial Genetics and Ecology (Bageco-2) held at the University of Wales, College of Cardiff which we organised on 11-12 April 1989.
Despite enormous efforts, over 100,000 papers and over $22 billion spent by the US taxpayer alone, the HIV-AIDS hypothesis has failed to produce any public health benefits, no vaccine, no effective drug, no prevention, no cure, not a single life saved.
The recent development of ideas on biodiversity conservation was already being considered almost three-quarters of a century ago for crop plants and the wild species related to them, by the Russian geneticist N.
The International Centre for Advanced Mediterranean Agronomic Studies (CIHEAM), established in 1962, is an intergovernmental organization of four- teen countries: Albania, Algeria, Egypt, France, Greece, Italy, Lebanon, Malta, Morocco, Portugal, Spain, Tunisia, Turkey and Yugoslavia.
Chromosomes Today Volume 12 records the plenary proceedings of the 12th triennial International Chromosone Conference, presenting an overview of the current concerns in the developing studies of animal, plant and human cytogenetics.
The rise of the neutral theory of molecular evolution seems to have aroused a renewed interest in mathematical population genetics among biologists, who are primarily experimenters rather than theoreticians.
The effects of isolation, area size, and habitat quality on the survival of animal and plant populations in the cultural landscape are central aspects of a research project started in Germany in 1993 (,Forschungsverbund, Isolation, FHichengroBe und BiotopquaIiHit', abbreviated to 'FIFB').
