Lake Veluwe, a Macrophyte-Dominated System Under Eutrophication Stress
ISBN: 9780792323204 / Angielski / Twarda / 376 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The structure and functioning of eutrophicated aquatic ecosystems has received considerable attention from limnologists as well as water managers in recent years. Stress has often been on pelagic food webs of deeper lakes whilst littoral systems or shallower lakes have been less thoroughly investigated. Since Dutch aquatic systems are shallow, as a rule, they form a notable exception. But here, too, the orientation was often on pelagic food webs.
The present study has a clearly different scope in that it takes the water plant as prime perspective. The editors consider water plants to be... The structure and functioning of eutrophicated aquatic ecosystems has received considerable attention from limnologists as well as water managers in r...

The Pantanal of Mato Grosso (Brazil): World's Largest Wetlands
ISBN: 9789401040181 / Angielski / Miękka / 125 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. For a naturalist and limnologist, the Pantanal has the extreme fascination of an "ultima Thule" ofundisturbed and little known wilderness. The scientific world at large is almost unaware of its richness. In an age when scientific research is overstretched because of lack of funds and the hands are full of urgentconservationtasks, it is the amateurtourist who unveils the beauty and the interestof this largest wetland ofthe world. I had the privilege of an outsider, well enough familiarized with Brazil, its language and scientific life, but independent enough of the daily chores of a local...

The Ecology of Loch Lomond
ISBN: 9789401043267 / Angielski / Miękka / 170 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Loch Lomond has long held a special place in the hearts of all the people of Scotland not only for its historic significance but also for the beauty of its countryside. Less widely known is the ecological importance of the area. It is the largest stretch of freshwater in Britain and the only loch to be crossed by the Highland Boundary Fault, one of the country's most important geological features.
The University of Glasgow has recognized the importance of this loch situated so near the main campus and has operated a field station on its shores since 1948. In the mid-1960s the field...

Studies on the Ecology of Tropical Zooplankton
ISBN: 9789401043823 / Angielski / Miękka / 295 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This volume reports on the findings of experts on tropical zooplankton gathered at a meeting in Kariba, Zimbabwe, in 1991. Some basic questions were asked on community composition and biodiversity in the tropics versus the non-tropics. Old ideas on the nature of zooplankton, which were found to be wider than the classical' rotifers, cladocerans and copepods, as well as on the number of species in tropical waters, are now beginning to break down accordingly as more and more blank spots in the tropics are explored and as more in-depth studies on the zooplankton of tropical lakes are becoming...

Ecology and Conservation of Southeast Asian Marine and Freshwater Environments Including Wetlands
ISBN: 9789401044141 / Angielski / Miękka / 325 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. A major concern among ecologists in and outside the ASEAN region is the degradation of the environment, and the overexploitation of freshwater and marine resources. There is as yet no indication that freshwater and marine resources are being managed on a sustainable basis, and loss of wetlands, whether freshwater swamps or mangrove swamps, is a major problem in the ASEAN region. Reclamation of mangrove swamps for aquaculture and agriculture seems to be a continuous activity here and the status of marine parks should also be examined in the light of recent resort development acitivities on...

Aquatic Birds in the Trophic Web of Lakes: Proceedings of a Symposium Held in Sackville, New Brunswick, Canada, in August 1991
ISBN: 9789401044936 / Angielski / Miękka / 524 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Birds are an integral part of most freshwater ecosystems (lakes, rivers, wetlands) but their role in the trophic dynamics of these water bodies has often been overlooked. As a conspicuous part of the biota of water bodies, aquatic birds are indicators of their trophic state both in terms of species composition (quality) as well as occupancy and breeding (quantity). Birds may also influence the trophic state of a water body by importing nutrients (.e.g. resident or migrating birds feeding on adjacent watersheds or the sea). Because of anthropogenic activities, predation or their mobility,...

Advances in Nemertean Biology: Proceedings of the Third International Meeting on Nemertean Biology, Y Coleg Normal, Bangor, North Wales, August 10-15
ISBN: 9789401049092 / Angielski / Miękka / 280 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In any scientific discipline, meetings with presented papers and discussions are the most effective stimulus to the advancement of knowledge. Nemerteans have long been largely neglected because their taxonomy is difficult: the need for histological study of serial sections has proved inhibiting to most zoologists. During the last twenty years, however, this intriguing phylum has attracted the attention both of increasing numbers of taxonomists as well as of workers interested in many aspects of, for example, their ecology, evolution, physiology and fine structure. The enthusiam stemming from...

Toolik Lake: Ecology of an Aquatic Ecosystem in Arctic Alaska
ISBN: 9789401052061 / Angielski / Miękka / 269 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The limnological study of Toolik Lake began in the Summer of 1975. This research was an outgrowth of the arctic IBP project which had focused mainly on small Arctic pond ecosystems on the Alaskan Arctic coastal plain. It was thought desirable to study larger, deeper lakes which contained fish to further generalizations developed during the IBP study.
Initial research on Toolik Lake and the surrounding lakes and ponds focused on process studies such as annual primary productivity of the lake or the vertical migration patterns of the resident zooplankton. In 1983 the philosophy of the... The limnological study of Toolik Lake began in the Summer of 1975. This research was an outgrowth of the arctic IBP project which had focused mainly o...

Sixteenth International Seaweed Symposium: Proceedings of the Sixteenth International Seaweed Symposium Held in Cebu City, Philippines, 12-17 April 19
ISBN: 9789401059091 / Angielski / Miękka / 668 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. International Seaweed Symposia have been held at three-year intervals for nearly 50 years. In the early days they formed the only international forum for marine phycologists, and although there are now frequent phycological meetings their value has not diminished, both because of the increased commercial importance of seaweeds, and because of the unique mix of disciplines that the meetings attract. Industrialists interact with chemists and biologists with the common aim of understanding seaweeds. The main development during the last few decades has been an increase in the cultivation of...
