An introductory discussion of basic chromosome structure andfunction preceeds the main text on the application ofcytogenetic approaches to the analysis of the manipulationof both the genetic make-up and the genetic transmissionsystem of plant breeding material.
Antarctic Ecosystems comprises 55 papers presented at the Fifth Symposium on Antarctic Biology held under the auspices of the Scientific Committee on Antarctic Research (SCAR) in Hobart, Australia, 29 August - 3 September, 1988.
In order to provide meaningful information for evaluating environmental consequences of alternative control strategies of air pollutant emissions, scientists have recently initiated numerous studies aiming at collecting and making use of regional data.
This book is a collection of papers presented at a NATO Advanced Research Workshop on "e;Biology and Molecular Biology of Plant-Pathogen Interactions"e; which was held at Dillington College, Ilminster, UK, 1-6 September 1985.
When trying to solicit authors for this book it became apparent that the causal factors for heterosis at the physiological and biochemical level are today almost as obscure as they were 30 years ago.
While the volumes hitherto published in the Springer Series in Synergetics have been devoted almost exclusively to the self-organized formation of structures in physics, chemistry and biology, the present monograph by Weidlich and Haag deals with the formation of "e;structures"e; (or "e;patterns"e;) in society.
With the increasing numbers of research workers and groups of investigators devoting themselves to the ecology of carabids I felt that the time had come to take stock of the existing knowledge in this field and to endeavour to weld my personal results and those of other workers into a comprehensive picture.
The term Fennoscandia is used to denote Finland and the Scandinavian peninsula, which comprises Norway and Sweden and sometimes also neigh- bouring districts of the USSR.
The contents of this volume involve selection, emendation and up-dating of papers presented at the NATO Conference "e;Mathe- matical Analysis of Decision problems in Ecology"e; in Istanbul, Turkey, July 9-13, 1973.
The period since World War II, and especially the last decade influenced by the International Biological Program, has seen enormous growth in research on the function of ecosystems.
Fifty million years ago, the Arctic Ocean was a warm sea, bounded by lush vegetation of the warm-temperate shores of Scandinavia, Siberia, Alaska and the Northwest Territories.
The message of sunspots from the interior of the Sun to the Earth's climate When Galileo was summoned before the Inquisition on April 12, 1633, the main accusations laid against him concerned the doubts he expressed about Aristotle's theory of the universe.
Climate is the most important component of the Earth's environment and climatic fluctuations have a strong impact on water supplies, vegetation, energy use etc.
Presented here are authoritative and up-to-date assessments of the homogenous and heterogenous chemical and physical processes occuring in the troposphere and stratosphere, especially during the "e;ozone hole"e; event.
Presented here is an analysis of plant development and plant metabolism using the tools of genetics and molecular biology, such as mutant analysis, mutation tagging, mapping using polymorphic characters and basic molecular biology techniques.
The cambium has been variously defined as follows: "e;The actively dividing layer of cells that lies between, and gives rise to, secondary xylem and phloem (vascular cambium)"e; (IAWA 1964); "e;A meristem with products of periclinal divisions commonly contributed in two directions and arranged in radial files.
