This book was released on 2013-06-29 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2nd International Symposium on Trichoptera was held at the University of Reading, England, 25-29 July 1977. It attracted 68 participants from 22 countries, which was a gratifying response to the circulation of about 250 workers on caddis flies. It was H. MALICKY who appreciated the need for a specialized meeting of this kind and organized the 1st International Symposium on Trichoptera, which was held at Lunz am See, Austria, 16-20 September 1974. This volume of Proceedings includes 38 papers; all except one were presented and discussed in the sessions listed in the programme. The papers were given in a lecture theatre of the Palmer Building, and demonstrations were laid out in a laboratory of the Department of Zoology where members met for their mprning and afternoon breaks. Members were accommodated in St Patrick's Hall, one of the University Halls of Residence. They were the guests of the University at an informal reception on 25 July. On the afternoon of 27 July an excursion was made to the River Lambourn at Bagnor near NeWbUry. This chalk stream has been the subject of an ecological study by a team from the Department of Zoology since 1970. The excursion was also an opportunity to see something of the local caddis fauna, and to do some collecting. The final session on 29 July, under the chairmanship of G. B. WIGGINS, was followed by a discussion on future plans.
Download or read book Conservation of Endangered Freshwater Fish in Europe written by Arthur Kirchhofer and published by Birkhäuser. This book was released on 2012-12-06 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two events have recently improved the prospects of protecting fish and their environment in Switzerland: the acceptance of a new Federal Water Protection Law in the plebiscite of May 17th 1992, and the new Federal Legislation on Fisheries, in force since January 1st 1994. With this legal framework, the possibilities for protection of nature and landscape have now considerably improved in Switzerland. The most important aims of the Federal Law on Water Protection are to safeguard the natural habitats of the native flora and fauna and water as the habitat of aquatic organisms. This includes not only the preservation or restoration of water quality in lakes and rivers, but also, in rivers used for hydroelectricity, irrigation or as industrial or other water supplies, the maintenance of sufficient water to fulfill the minimal requirements for fish. However, good quality water in sufficient quan tities alone is not enough to guarantee the survival of fish. Intact fish habitats comprise various phYsical structures including plenty of hiding places, hunting grounds, reproduction and nursery areas within suitable distances from each other. This third aspect of conservation and restoration of aquatic habitats is a central point in the new Federal Law on Fisheries. Whereas the former versions of this law were more concerned with fishery regulations, the recent legislation defines new areas of responsibility for the federal and the cantonal governments.

Download or read book Lake Pavin written by Télesphore Sime-Ngando and published by Springer. This book was released on 2016-10-31 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

Download or read book Lessepsian Migration written by F.D. Por and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are few achievements of modern man which can compare to the Suez Canal. In Egypt-the land of the most famous wonders of antiquity-the Suez Canal was built as the first technical wonder ofthe industrial revolution. Ferdinand de Lesseps was a man straddling two epochs-the romantic utopism of Saint Simon and the modern world of technocracy. The gigantic project was at its start shouldered by the crowds of tens of thousands of forced laborers still available and ended as a show-piece for modern mechanical earth-moving techniques. The canal builders themselves were still polyhistors in the old sense: engineers cum-zoologists; naval officers-cum-geologists; diplomats meddling with chem istry. During the four generations of the existence of the Suez Canal, the fateful professional narrowmindedness became progressively worse. The engineers con tinued their work in and around the Canal, but they became oblivious and unresponsive to the environmental impact, to the fascinating changes in the biotic scenery which they were producing with their own hands.

They are a distinctive and popular group of birds, and include two very familiar and attractive British species - the Stonechat and Whinchat. This volume is primarily an identification guide, using colour plates and photographs to illustrate the various races and plumages, but the text also covers the biology, habitat and range of each species. DNA data is presented, and there are distribution maps for each species.

Download or read book The Birds of Africa Volume VIII written by Roger Safford and published by Bloomsbury Publishing. This book was released on 2020-09-17 with total page 1025 pages. Available in PDF, EPUB and Kindle. Book excerpt: Universally recognised as by far the most authoritative work ever published on the subject, The Birds of Africa is a superb multi-contributor reference work, with encyclopaedic species texts, stunning paintings of all species and numerous subspecies, informative line drawings, detailed range maps, and extensive bibliographies. Each volume contains an Introduction that brings the reader up to date with the latest developments in African ornithology, including the evolution and biogeography of African birds. Diagnoses of the families and genera, often with superspecies maps, are followed by the comprehensive species accounts themselves. These include descriptions of range and status, field characters, voice, general habits, food, and breeding habits. Full bibliographies, acoustic references, and indexes complete this scholarly work of reference. This eighth and final volume covers the Malagasy region which comprises Madagascar and the various islands and archipelagos of the Indian Ocean including the Seychelles, the Comoros, Mauritius and Réunion. Every resident and migrant species is covered in full detail, comparable to other volumes in the series, and with a colour map for each species. Vagrants are treated in less detail. All species are illustrated on a beautiful series of 64 colour plates, with original artwork from John Gale and Brian Small. This is a major work of reference on the birds of the region and will remain the standard text for many years to come.
