Download or read book Prospects in Systematics written by D. L. Hawksworth and published by . This book was released on 1988 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book critically reviews the developments and achievements of systematics in the 50 years since the foundation of the Systematics Association in 1937, and more particularly since the appearance of The New Systematics, edited for the Association by Sir Julian Huxley in 1940. Botanists, microbiologists, palaeontologists, and zoologists--theoreticians and practitioners alike--consider fundamental aspects of the subject and the directions in which it might develop into the next century. The result is a description of a highly active subject adapting concepts and practices to accommodate exciting new information from expanding areas of research--one which, however, also needs to take increased note of the requirements of its users. The main challenge for systematics in the coming decades emerges as the need to re-establish its central unifying position as the keystone of biology.
Download or read book Vegetation of the Canary Islands written by Marcelino J. del Arco Aguilar and published by Springer. This book was released on 2018-07-18 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volcanic and oceanic nature of the Canary Islands, its rich plant biodiversity and high rate of endemism, as well as the relict character of some of its plant communities make it a territory of great biological interest. The main geographic, climatic, bioclimatic, biogeographic and floristic features of the Islands are shown and related to the distributional pattern of potential communities along an altitudinal gradient. Current vegetation units and their ecology are described and illustrated with numerous pictures. Potential vegetation units are summarized and comprehensive maps of the potential natural vegetation for each island are given. Human impact on the natural landscape, the occurrence of invasive plants, and the probable impact of climate change on the flora and vegetation are discussed. The conservation status of flora and vegetation are assessed. Four appendixes include a syntaxonomical scheme, a brief history of botanical studies and explorations in the Islands, ethnobotanical notes, and a list of selected literature.

Download or read book Phylonyms written by Kevin de Queiroz and published by CRC Press. This book was released on 2020-04-30 with total page 1030 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phylonyms is an implementation of PhyloCode, which is a set of principles, rules, and recommendations governing phylogenetic nomenclature. Nearly 300 clades - lineages of organisms - are defined by reference to hypotheses of phylogenetic history rather than by taxonomic ranks and types. This volume will document the Real World uses of PhyloCode and will govern and apply to the names of clades, while species names will still be governed by traditional codes. Key Features Provides clear regulations for implementing new guidelines for naming lineages of organisms incorporates expressly evolutionary and phylogenetic principles Works with existing codes of nomenclature Eliminates the reliance on rank-based classification in favor of phylogenetic relationships Related Titles: Rieppel, O.

Download or read book The Lichen Forming Fungi written by D. L. Hawksworth and published by Springer. This book was released on 1984-09-01 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lichen assocIations include some of the oldest living organisms and represent a major nutritional method adopted by one in five fungi. Major advances in our knowledge of these biologically fascinating organisms have been made in recent years and they now have a great deal to offer to teaching in colleges and universities. In addition to being examples of biotrophic systems, they merit discussion in courses on fungal phylogeny, fungal nutrition, ecology, ecophysiology, biogeography, evolution, chemo taxonomy, environmental monitoring, and algology. As all aspects of lichenology cannot be treated adequately in a book of this length, we have emphasized topics which we have found to be of particular interest to a advanced undergraduate and postgraduate biologists (or biogeographers) or those contemplating more detailed studies in particular areas. Consequently we have endeavoured to place lichen associations in the broader context of biological and biogeographical teaching. Examples are drawn from many areas of the world, including North America, but it is inevitable that European ones predominate, as lichens there are better known than in other regions. Technical terms are defined when first used, and definitions can therefore be located with the aid of the index. Lichens are not a systematic group and so are not appropriately treated in a groups-orientated programme, but are a major biological phenomenon all too commonly accorded scant attention in university courses.
Download or read book Yeast technology written by Gerald Reed and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yeasts are the active agents responsible for three of our most important foods - bread, wine, and beer - and for the almost universally used mind/ personality-altering drug, ethanol. Anthropologists have suggested that it was the production of ethanol that motivated primitive people to settle down and become farmers. The Earth is thought to be about 4. 5 billion years old. Fossil microorganisms have been found in Earth rock 3. 3 to 3. 5 billion years old. Microbes have been on Earth for that length of time carrying out their principal task of recycling organic matter as they still do today. Yeasts have most likely been on Earth for at least 2 billion years before humans arrived, and they playa key role in the conversion of sugars to alcohol and carbon dioxide. Early humans had no concept of either microorganisms or fermentation, yet the earliest historical records indicate that by 6000 B. C. they knew how to make bread, beer, and wine. Earliest humans were foragers who col lected and ate leaves, tubers, fruits, berries, nuts, and cereal seeds most of the day much as apes do today in the wild. Crushed fruits readily undergo natural fermentation by indigenous yeasts, and moist seeds germinate and develop amylases that produce fermentable sugars. Honey, the first con centrated sweet known to humans, also spontaneously ferments to alcohol if it is by chance diluted with rainwater. Thus, yeasts and other microbes have had a long history of 2 to 3.

Download or read book Etymological Dictionary of Succulent Plant Names written by Urs Eggli and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Names are important elements to handle the diversity of items in daily life - persons, objects, animals, plants, etc. Without such names, it would be difficult to attach information to such items and to communicate information about them, and names are usually used without giving them much thought. This is not different for plants. When dealing with plants, however, it soon becomes apparent that the situation is somewhat more complex. Botanists use Latin names to bring order into the vast diversity, while everyday usage resorts to vemacular or "popular" names. As practical as these vernacular names are (it is not suggested that you should ask your greengrocer for a kilo gram of Solanum tuberosum or Musa paradisiaca subsp. sapientum), their most important draw back is the fact that they vary widely, not only from one language to another but also from coun try to country, even from region to region within a large country. More importantly, vemacular names in any given language are usually only available for the plants growing locally, or for plants of some special importance, such as crops and vegetables, medicinal plants, or important garden plants. For all other plants, the Latin names used by botanists and other scientists have to be employed. Such names often appear complicated or even awkward to the ears of those not accustomed to them.
