Schweingrubers neustes Werk stellt anatomische und morphologische Ausdrucksformen von Bäumen, Sträuchern, Zwergsträuchern und mehrjährigen Kräutern in einen ökologischen Kontext. Untersucht werden vornehmlich spezifische Reaktionen des Holzkörpers auf Verletzung, Lageveränderung, Entlaubung, auf Lichtmangel, Kälte- und Trockenstress, auf prekäre Lebensbedingungen und Konkurrenz. - Das Repertorium bezieht sich auf die unterschiedlichsten Standorte und auf die Ganzheit der Gehölze, von der Wurzel bis zur Zweigspitze und vom Keimling bis zum adulten und im Abbau begriffenen Holz - in lichtmikroskopischer Dimension.

Dendrochronologie - Umweltgeschichte - Schweiz.

Dendrochronology and wood anatomy developed for decades as two independent scientific fields. It was only in the last decade that it was made clear that the dimension of time is the fourth dimension for both sciences and that it was demonstrated that wood anatomy and dendrochronology are perfect partners. The main aim of this book is to show the hidden ecological richness in stems and roots from trees, shrubs and herbs. It should encourage researchers to consider the anatomic microcosm of wood plants and use it as a retrospective source of information, solving problems related to ecophysiology, competition, site conditions, population biology, earth science, wood quality and even human history.

This unique and attractive open access textbook combines the beauty of macroscopic pictures of plant stems with the corresponding colorfully stained images of anatomical micro-structures. In contrast to most botanical textbooks, it presents all the stem characteristics as photographs and shows the microscopic reality. The amount of text is reduced to a minimum, and the scientific information is highlighted with short legends and labeled photographs, allowing readers to focus on the pictures to easily understand how the anatomical structures relate to genetic, ecological, decomposition and technical influences. It includes a chapter devoted to simple anatomical preparation techniques, and further chapters showing the cell content, cell walls, meristematic tissues and stem structures of all major taxonomic units and morphological growth forms in various ecological and climatic regions from subarctic to equatorial latitudes, as well as structures of fossil, subfossil and technically altered wood. This textbook appeals to students and researchers in the fields of plant anatomy, taxonomy, ecology, dendrochronology, history, plant pathology, and evolutionary biology as well as to technologists.

Here we present 104 features of culms and 103 features of rhizomes of crosssections of monocotyledonous plants occurring in the temperate and Mediterranean zone along altitudinal gradients from the lowland to the alpine zone. It is the first time that a synthesis of monocotyledonous-anatomical features of Western European plants is presented. The feature list is based on microslides from 580 species within 28 families. Included are culms of grasses, sedges and rushes and flower stalks of many other plants. Culms of grasses can be made of dry, herbarium material. For all other species only fresh material allows to make sections without drying artefacts. Blue-red color photographs in magnification of 100 and 400 times contain information about lignification and many structural features. The list of features clearly shows, that the anatomical variability with monocotyledonous plants is almost as high as in dicotlyedons. The features indicate relations to taxonomy and ecological conditions.
