Illustrated Handbook of Succulent Plants
This handbook, consisting of six volumes, covers over 9000 taxa of succulents (excluding cacti), which have the ability to store water in their stems, leaves, or underground organs. In addition to the volumes on Monocotyledons and Dicotyledons, separate volumes are devoted to those families with predominantly succulent members, which show an especially great diversity, namely Aizoaceae, Asclepiadaceae and Crassulaceae. Following an alphabetical listing of families, genera and species, detailed descriptions are given, including the taxonomy with synonyms, data on the distribution and ecology, references, and keys to genera, species or subspecies. Over 2000 superb colour photographs complete this inventory of succulent plants.
Flowering Plants. Monocotyledons
When Rolf Dahlgren and I embarked on preparing this book series, Rolf took prime responsibility for monocotyledons, which had interested him for a long time. After finishing his comparative study and family classification of the mono cots, he devoted much energy to the acquisition and editing of family treatments for the present series. After his untimely death, Peter Goldblatt, who had worked with him, continued to handle further incoming monocot manuscripts until, in the early 1990s, his other obligations no longer allowed him to continue. At that time, some 30 manuscripts in various states of perfection had accumulated, which seemed to form a solid basis for a speedy completion of the FGVP monocots; with the exception of the grasses and orchids which would appear in separate volumes. I felt a strong obligation to do everything to help in publishing the manuscripts that had been put into our hands. I finally decided to take charge of them personally, although during my life as a botanist I had never seriously been interested in mono cots.
Ökologie der Abwasserorganismen
Was haben Mikrobiologie und Ökologie der Abwassertechnik zu bieten? Zur Optimierung der Abwasserreinigung sowie zur Früherkennung und Vermeidung von Störungen ist es notwendig, die Organismen zu kennen, von denen die Reinigungsleistung vollbracht wird, und zu wissen, welche Wechselwirkungen sie untereinander entwickeln und wie sich Veränderungen des Nährstoffangebots auf Zusammensetzung und Effektivität der Population auswirken. Darüberhinaus bietet die mikrobielle Ökologie auch Ansätze, die biologischen Ursachen von Schwimmschlamm, Blähschlamm und Schaumbildung besser zu verstehen und ihnen frühzeitig gezielt entgegenzuwirken. Anhand konkreter Beispiele werden Möglichkeiten und Grenzen klassischer und gentechnischer Methoden zur Charakterisierung der Abwassermikroorganismen demonstriert.

Progress in Botany
This seris keeps scientists and advanced students specialized on a particular subject informed of the latest developments and results in all different areas of botany. The present volume includes reviews on structuralbotany, physiology, genetics, taxonomy, geobotanic, as well as a contribution treating seed dispersal.
Flowering Plants · Dicotyledons
This volume - the first of this series dealing with angiosperms - comprises the treatments of 73 families, representing three major blocks of the dicotyledons: magnoliids, centrosperms, and hamamelids. These blocks are generally recognized as subclasses in modern textbooks and works of reference. We consider them a convenient means for structuring the hundreds of di cotyledon families, but are far from taking them at face value for biological, let alone mono phyletic entities. Angiosperm taxa above the rank of family are little consolidated, as is easily seen when comparing various modern classifications. Genera and families, in contrast, are comparatively stable units -and they are important in practical terms. The genus is the taxon most frequently recognized as a distinct entity even by the layman, and generic names provide the key to all in formation available about plants. The family is, as a rule, homogeneous enough to conve niently summarize biological information, yet comprehensive enough to avoid excessive re dundance. The emphasis in this series is, therefore, primarily on families and genera.
