Download or read book Biogeography and Ecology of Southern Africa written by Marinus J.A. Werger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southern Africa is certainly not a naturally bounded area so that there are several possibilities for delineating it and concepts about its extent. Wellington* discussed the various possibilities for delineation and suggested that one line stands out more clearly and definitely as a physical boundary than any other, namely the South Equatorial Divide, the watershed between the ZaIre, Cuanza and Rufiji Rivers on the one hand and the Z ambezi, Cunene and Rovuma Rivers on the other. This South Equatorial Divide is indeed a major line of separation for some organisms and is also applicable in a certain geographical sense, though it does not possess the slightest significance for many other groups of organisms, ecosystems or geographical and physical features of Africa. The placing of the northern boundary of southern Africa differs in fact strongly per scientific dis cipline and is also influenced by practical considerations regarding the possibilities of scientific work as subordinate to certain political realities and historically grown traditions. This is illustrated, for example, in such works as the Flora of Southern Africa, where the northern boundary of the area is conceived as the northern and eastern political boundaries of South West Africa, South Africa and Swaziland. Botswana, traditionally included in the area covered by the Flora Zambesiaca, thus forms a large wedge in 'Southern Africa'.
Download or read book The Ecology of Regulated Streams written by James Ward and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for an international symposium on regulated streams was conceived over an open-faced sandwich at the R&dhus in Copenhagen when we attended the Congress of the Societas Internationalis Lim nologiae in summer 1977. Although· we were aware that various col leagues were working on ecological problems in reservoir tailwaters, we did not fully comprehend the magnitude of worldwide stream regu lation nor the extent of interest in the subject. Such revelations are reflected in the 21 papers included in this book. The authors have summarized current understanding of the ecology of regulated streams and attempted to convey the importance and direction of future scientific investigations in stream ecosystems altered by upstream impoundments. The First International Symposium on Regulated Streams was the plenary event at the 27th annual meeting of the North American Benthological Society, April 18-20, 1979, in Erie, Pennsylvania. More than 500 colleagues attended. We gratefully acknowledge the support granted by the National Science Foundation; these funds permitted intellectual exchange between scientists from eight coun tries on four continents. We extend personal thanks to Dr. K. W. Stewart, President of NABS, and the NABS Program Committee, including Drs. E. C. Masteller, E. R. Brezina, and W. P. Kovalak. These individuals and other officers and members of the Executive Committee assisted us with the many details leading to organization and staging of a scientific forum. Discussions with Dr. John Cairns, Jr. and Dr. G. Richard Marzolf during the early planning stage were most helpful.

Book excerpt: This bibliography includes scientific articles on the Drakensberg, Maloti and Adjacent Lowlands published between 1808 and 2019. Although focussing on material appearing in accredited journals, there is such a wealth of information in the form of unpublished, yet traceable, reports, documents, presentations and dissertations, these are also included. The bibliography has two parts – a complete list arranged alphabetically, and the same references arranged in 33 different disciplines. These range from Palaeobotany with 17 entries, to Rock Art with 502 entries.

Download or read book Remote Sensing of Subtropical Coastal Environments Natal South Africa written by A. R. Orme and published by . This book was released on 1974 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote sensing of subtropical coastal environments is examined with particular reference to Natal, South Africa. Vertical color infrared (CIR) imagery at a scale of 1:25,000 with 60% forward overlap forms the basis for analysis, supported by similar panchromatic coverage and hand-held oblique panchromatic and CIR imagery. The CIR imagery used in this study contributes significantly to the understanding of the physical, biological, and human components of the Natal coastal environment and, by extension, to environemntal analysis of 2000 km of similar coastline from central Mozambique to eastern Cape Province. (Modified author abstract).
