Book Description
The field of plant taxonomy has transformed rapidly over the past fifteen years, especially with regard to improvements in cladistic analysis and the use of new molecular data. The second edition of this popular resource reflects these far-reaching and dramatic developments with more than 3,000 new references and many new figures. Synthesizing current research and trends, Plant Taxonomy now provides the most up-to-date overview in relation to monographic, biodiversity, and evolutionary studies, and continues to be an essential resource for students and scholars. This text is divided into two parts: Part 1 explains the principles of taxonomy, including the importance of systematics, characters, concepts of categories, and different approaches to biological classification. Part 2 outlines the different types of data used in plant taxonomic studies with suggestions on their efficacy and modes of presentation and evaluation. This section also lists the equipment and financial resources required for gathering each type of data. References throughout the book illuminate the historical development of taxonomic terminology and philosophy while citations offer further study. Plant Taxonomy is also a personal story of what it means to be a practicing taxonomist and to view these activities within a meaningful conceptual framework. Tod F. Stuessy recalls the progression of his own work and shares his belief that the most creative taxonomy is done by those who have a strong conceptual grasp of their own research.

Book Description
Plants growing in tropical alpine environments (at altitudes above the closed canopy forest and below the limit of plant life) have evolved distinct forms to cope with a hostile environment characterized by cold, drought and fire. Unlike temperate alpine environments, where there are distinct seasons of favourable and unfavourable conditions for growth, tropical alpine habitats present summer conditions every day and winter conditions every night. Using examples from all over the tropics, this fascinating account reviews, for the first time, the unique form and functional relationships of tropical alpine plants examining both their physiological ecology and population biology. It will appeal to anyone interested in tropical vegetation and plant physiological adaptations to hostile environment, as well as to researchers in biogeography and ecology.

Book Description
This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.

Book Description
Biosystematic studies on the Rubiaceae have a long tradition at the Institute of Botany in Vienna. Within this family the Anthospermeae, and especially its African and Madagascan members, are of particular interest because of several aspects in their evolution: I) Perfection of anemophily within an otherwise nearly exclusively zoophilous family; 2) transitions from hermaphrodity to polygamy and finally dioecy; 3) differentiation from large and long-lived shrubs to short-lived herbs; 4) adaptive radiation from humid to seasonally dry, fire-exposed and xeric habitats. However, morphological diversity linked to sexual differentia tion, modificatory plasticity, and eco-geographical polymorphism have for a long time hampered our understanding of the relationships among these African Anthospermeae. Thus, it was imperative to put special emphasis on field observations and to carry out a variety of experiments with cultivated plants in addition to the analysis of an enormous herbarium material. The author, for this reason, carried out extensive field work, often under very adverse conditions, and covered most African countries from Ethiopia to Southern Africa and twice visited Madagascar. In this way a multitude of data was accumulated on the group in respect to germination and growth form, vegetative and reproductive morphology, anatomy and biology, embryology, karyology, crossing relationships, phytochemistry, distribu tion and ecology, etc.

Book Description
Originally published in 1974, Arctic and Alpine Environments examines, the relatively simple ecosystems of arctic and alpine lands that still occupy extensive areas little disturbed by modern technology. The book argues that there is a necessity for carefully controlled development of the resources of these regions and suggests that there is a risk of irreversible disturbance without full understanding of these regions. This book provides a detailed documentation of cold-stressed arctic and alpine terrestrial environments and systematically deals with the present and past physical environment – climate, hydrology and glaciology; biota – treeline, vegetation, vertebrate zoology, and historical biogeography; abiotic processes – geomorphological and pedological and the role of man – bioclimatology, archaeology and technological impact, including radioecology. The book will appeal to academics and students of environmental and biological science, as well as providing a significant source for conservationists’, government agencies and industrial organizations.
