(6) Moist evergreen Afromontane forest (with the subtypes (6a) Primary or mature secondary moist evergreen Afromontane forest, and (6b) Edges of moist evergreen Afromontane forest, bushland, woodland and wooded grassland). (7) Transitional rain forest. (8) Ericaceous belt. (8) Afroalpine belt. (10) Riverine vegetation. (11) Fresh-water lakes, etc. (with the subtypes (11a) Fresh-water lake vegetation (open water) and (11b) Freshwater marshes and swamps, floodplains and lake shore vegetation). (12) Salt lakes, etc. (with the subtypes (12a) Salt lake vegetation (open water) and (12b) Salt pans, saline brackish and intermittent wetlands and salt-lake shore vegetation)"--Synopsis.
Download or read book World Checklist of Cyperaceae written by Rafaël Govaerts and published by Royal Botanic Gardens Kew. This book was released on 2007-01 with total page 765 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sedge family, Cyperaceae, is the third largest family of monocotyledonous plants. They are of significant economic importance, especially among rural communities in the tropics, where sedges are intensively used. The World Checklist of Cyperaceae provides a single source guide to the correct names of all sedges, the source of their publication and indicating which names are currently accepted and which are synonyms. It will be a standard nomenclatural reference for further research into this important family. This makes it an invaluable reference for agriculturists, horticulturists, ecologists, conservationists and plant biologists.
Download or read book Bird Census Techniques written by Colin J. Bibby and published by Academic Press. This book was released on 2012-12-02 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild birds are counted for a wide variety of reasons and by a bewildering array of methods. However, detailed descriptions of the techniques used and the rationale adopted are scattered in the literature, and the newcomer to bird census work or the experienced bird counter in search of a wider view, may well have difficulty in coming to grips with the subject as a whole. While not an end in itself, numerical and distributional census work is a fundamental part of many scientific and conservation studies, and one in which the application of given standards is vital if results are not to be distorted or applied in a misleading way. This book provides a concise guide to the various census techniques and to the opportunities and pitfalls which each entails. The common methods are described in detail, and illustrated through an abundance of diagrams showing examples of actual and theoretical census studies. Anyone with a bird census job to plan should be able to select the method best suited to the study at hand, and to apply it to best effect within the limits inherent in it and the constraints of the particular study. The Royal Society for the Protection of Birds and the British Trust for Ornithology have for many years pioneered the collaboration of amateurs and professionals in various census studies. Three members of their staff, each with extensive field experience, now pool the knowledge of these investigations to lay the groundwork for sound census work in future years.

Available in PDF, EPUB and Kindle. Book excerpt: A project spanning over three decades has come to fruition with the publication of the Flora of the Marquesas Islands authored by David H. Lorence (NTBG) and Warren L. Wagner (Smithsonian Institution). This two volume, 1135 page opus is a complete account of all of the vascular plants found in the Marquesas Islands and was developed and written on a web site format. The Marquesas are a volcanic archipelago of 12 islands and numerous islets situated within the eastern part of French Polynesia, making it one of the most isolated groups of oceanic islands. This collaborative project between the National Tropical Botanical Garden, the Smithsonian Institution, and the Délégation à la Recherche de la Polynésie française is intended to further knowledge of the flora of this remote archipelago.Volume 1 (411 pages, published in December 2019) includes introductory chapters covering the project's history, Marquesas geology and climate, history of plant collecting in the islands, flora and vegetation, plant communities, threats to the flora, conservation status of species including IUCN Red List recommendations, critical conservation considerations, and many other aspects, as well as taxonomic treatments of the native and naturalized lycophytes (fern allies), ferns, and monocots. Volume 1 is richly illustrated with 134 figures including 111 color plates, 21 elegant line drawings by Smithsonian illustrator Alice Tangerini, and two maps. A complete list of all exsiccatae (specimens studied) is given in the Exsiccatae section. Volume 2 (722 pages, published in September 2020) covers the dicots, dicot exsiccatae, a list of cultivated plants, a list of all literature cited, and an index to both volumes. Volume 2 comprises is richly illustrated with 252 color figures and line drawings.
Download or read book Ordination of Plant Communities written by R.H. Whittaker and published by Springer. This book was released on 1978 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large part of ecological research depends on use of two ap proaches to synthesizing information about natural communities: classification of communities (or samples representing these) into groups, and ordination (or arrangement) of samples in relation to environmental variables. A book published in 1973, 'Ordination and Classification of Communities,' sought to provide, through contributions by an international panel of authors, a coherent treatise on these methods. The book appeared then as Volume 5 of the Handbook of Vegetation Science, for which R. TuxEN is general editor. The desire to make this work more widely available in a less expensive form is one of the reasons for this second edition separating the articles on ordinction and on classification into two volumes. The other reason is the rapid advancement of understanding in the area of indirect ordination-mathematical techniques that seek to use measurements of samples from natural communities to produce arrangements that reveal environmental relationships of these communities. Such is the rate of change in this area that the last chapter on ordination in the first edition is already, 4 or 5 years after it was written, out of date; and new techniques of indirect ordination that could only be mentioned as possibilities in the first edition are becoming prominent in the field. In preparing the second edition the chapter on evaluation of ordinations has been rewritten, a new chapter on recent developments in continuous multivariate techniques has been included, and references to recent work have been added to other chapters.
