Ecological science, the Biosphere

In 1971 the International Society of Tropical Ecology and the International Association for Ecology held a meeting on Tropical Ecology, with an emphasis on organic production in New Delhi, India.

Vor noch gar nicht langer Zeit, nämlich im Jahre 1887, wurde von dem Meeresbiologen VICTOR HENSEN der Begriff Plankton geprägt; etwas später, im Jahre 1890, wurde er von HAECKEL genauer definiert.

The role of arthropods in forest ecosystems is poorly understood.

Modern forest products research had its start hardly fifty years ago.

This volume contains the Proceedings of the International Conference in Population Biology held at The University of Alberta, Edmonton, Canada from June 22 to June 30, 1982.

A century of research on heterostylous plants has passedsince the publication of Charles Darwin's book "e;TheDifferent Forms of Flowers on Plants of the Same Species"e; in1877 summarizing his extensive observations and experimentson these complex breeding systems involving geneticpolymorphisms of floral sex organs.

The Institute of Ecology (TIE) was organized to provide a mech- anism for addressing ecological and environmental issues that were beyond the special interests of ecology as a profession.

The present lecture notes cover a first course in th~ most common types of stratified flows encountered in Environ- mental Hydraulics.

After UNCED (United Conference on Environment and Development, Rio de Janeiro, July 1992), a second edition of Desertification was necessary.

This book presents the proceedings of a workshop on community ecology organized at Davis, in April, 1986, sponsored by the Sloan Foundation.

What little we know of the biology of desert invertebrates stems largely from inferences based on intensive and repeated observations.

A series of concise books, each by one or several authors, will provide prompt, world-wide information on approaches to analyzing ecological systems and their interacting parts.

Root disease epidemics, because much of the activity takes place in soil and out of sight, pose special challenges to growers who seek to manage them and to scientists who study them.

The past two decades have seen a remarkable broadening of interest in global warming from a research concern on the part of a limited number of scientists to a political problem on a worldwide scale.

Das vorliegende Buch ist eine Zusammenstellung über die Methodik von Messungen des aktuellen Wasser- und Stofftransportes in Fließgewässern.

The ocean plays a central role in determining the climate of the earth.

Provided here are both underlying theory and recent resultsconcerning the propagation and use of clones in research andin production forestry.

The honeybee (Apis melli/era L.

Biological markers used to assess the effects of environmental pollution have attracted considerable attention from regulatory agencies and are currently under evaluation at a number of research facilities throughout the world.

Methane plays many important roles in the earth's environment.

Key biogeochemical events in the ocean take place in less than a second, are studied in experiments lasting a few hours, and determine cycles that last over seasons or even years.

Peritrophic membranes are secretion products of the midgut.

Can a continuous growth of agriculture be achieved in the sub-Sahara region without inducing irreversible damage to the ecosystem?

Wild taxa are invaluable sources of resistance to diseases, insects/ pests, nematodes, temperature extremes, salinity and alkalinity stresses, and also of nutritional quality; adaptation; genetic diversity and new species.

Because of the great variety of problems which this genus presents to biologists, Oenothera belongs to the best-known genera of plants not used economically.

The esculent Lycopersicon esculentum, long thought to be poisonous, has become a major U.

Clonal forestry has come of age.

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.

The vast majority of the world's lakes are small in size and short lived in geological terms.

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.

Rice is the most important cereal crop which feeds more than half the population of the world.

In contrast to animals, plants are immobile and, thus, cannot leave a drastically changed environment.

Food webs hold a central place in ecology.

Attention to viral infections and pathology previously focussed on diseases of economically important fish.

The aim of this study is twofold: to provide a theoreti- cal and an applied analysis of multispecies fisheries.

This book is not a conventional review of diving physiology.

In addition to the more or less static properties of the environ- ment, plants and animals must cope with its temporal variations.
