As stated many times before the purpose of Orchid Biology, Reviews and Perspectives (OB) is to present reviews on all aspects of orchids. The aim is not to balance every volume, but to make a balanced and wide ranging presentation of orchids in the series as a whole. The chapters in this, the last volume of the series, range over a number of topics which were not covered before. Singapore is justly famed for its orchids. They can be seen on arrival (or dep- ture) in its modern, highly efficient and comfortable Changi Airport and on the way from it to town. Vanda Miss Joaquim, the first hybrid to come from Singapore became its National Flower. This natural hybrid can be seen on its currency, stamps, and public and private decorations. Many excellent breeders, starting with Prof. Eric Holttum who bred the first man made hybrid (Spathoglottis Primrose), produced numerous magnificent hybrids and won countless awards in Singapore and elsewhere. These hybrids served to enrich the country’s orchid mystique. In the opening chapter of this volume Dr. Teoh Eng Soon (Western style: Eng Soon Teoh), himself a prize winning orchid breeder, grower and author writes about some of the breeders who contributed to the Singapore orchid fame. Prof. Hans Fitting was one of the best known plant physiologists of his time. As a young man he studied the effects of pollen on orchid flowers.

Two questions could not be avoided in the avant-propos of this book; (i) what is the importance to man of ruminant livestock, and (ii) what results of practical relevance in the growing mountain of scientific verbiage could be found in the Proceedings of this Symposium. Herbivores are an integral and critical part of the natural ecosystem which must be preserved because of their impact on human welfare. Wh at makes ruminants especially important to man is that they can thrive on fibrous forage and are thus the only viable enterprise over much of the earth's surface where crop growing is impracti cable. They contribute a wide array of products in addition to 50000 000 tonnes ofmeat (1977) and represent a 'capital reserve' that can be drawn upon in times of emergency: milk for example (450000000 tonnes) can make the difference between subsistence and starvation. About 60% of the world's meat and 80 % of the milk are produced by one third of the world ruminant population in the developed regions and as much as 99 % of the power for agriculture is provided by the ruminant population in developing countries. For the next two decades, a probable increase by 30 % for . cattle and buffalo and more than 40 % for sheep and goats is expected by improving health, fertility, nutrition and genetic potential rather than feed resources.

Dieses Buch bietet einen fundierten Überblick über die geomorphologische Formung und vegetationsgeschichtliche Entstehung der mitteleuropäischen Auenlandschaften. Der Schwerpunkt liegt auf der Darstellung der Lebensgemeinschaften, zudem wird die außerordentliche Biodiversität dieser stark bedrohten Lebensräume betont. Bodenkundliche, geobotanische und zoologische Aspekte werden im Licht der aktuellen Forschungsliteratur diskutiert. Das Besondere ist der ganzheitliche und interdisziplinäre Blickwinkel, bei dem ökosystemale Zusammenhänge im Fokus stehen. Das Buch vertritt einen wissenschaftlichen Anspruch in der Beschreibung der Lebensformen in Auenbiotopen, möchte aber zugleich dabei nicht auf die Darstellung der Schönheit dieser Landschaften und ihrer faszinierenden Tier- und Pflanzengemeinschaften verzichten. Aussagekräftige und zugleich stimmungsvolle Farbbilder laden den Leser ein, sich mit der Einzigartigkeit der heimischen Auenlandschaften zu beschäftigen. Wissenschaftler und Studierende aus verschiedenen Disziplinen ebenso wie im Naturschutz tätige Praktiker und biologisch interessierte Laien werden die enge Verzahnung von Text und Fotografie in diesem Buch sicherlich zu schätzen wissen.

This work presents the state of the art of aquatic and semi-aquatic ecological restoration projects in The Netherlands. Starting from the conceptual basis of restoration ecology, the successes and failures of hundreds of restoration projects are described. Numerous successful projects are mentioned. In general ecological restoration endeavours greatly benefit from the progressive experience achieved in the course of the years. Failures mainly occur through insufficient application of physical, chemical or ecological principles. Spontaneous colonization by plants and animals, following habitat reconstruction, is preferred. However, sometimes the re-introduction of keystone species (e.g. eelgrass, salmon, beaver) is necessary in case the potential habitats are isolated or fragmented, or if a seed bank is lacking, thus not allowing viable populations to develop. Re-introducing traditional management techniques (e.g. mowing without fertilization, low intensity grazing) is important to rehabilitate the semi-natural and cultural landscapes that are so characteristic for The Netherlands.
