Atlas of Chrysophycean Cysts
ISBN: 9781402000416 / Angielski / Twarda Termin realizacji zamówienia: ok. 5-8 dni roboczych. Chrysophytes are a diverse and often abundant group of primarily freshwater algae that are characterized by the endogenous formation of siliceous cysts or stomatocysts (also called statospores or statocysts). Cyst morphology is highly variable, but believed to be species-specific. Cysts have continued to receive attention from phycologists and especially paleoecologists, who use these indicators for assessments of environmental change.
In this volume, we have compiled descriptions, using both scanning electron and light microscopy, as well as line drawings, for 176 new cyst descriptions....

Environmental Biology of European Cyprinids: Papers from the Workshop on 'The Environmental Biology of Cyprinids' Held at the University of Salzburg,
ISBN: 9780792314844 / Angielski / Twarda / 233 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Members of the family Cyprinidae dominate most of the aquatic habitats of Europe, from eutrophic warm water ponds to mountain lakes. The family comprises generalists and specialists, herbivorous, planktovorous and even one piscivorous species; slow-moving grazers as well as fast-swimming inhabitants of the pelagial of lakes. Due to their diversity and abundance, cyprinids play key roles in every ecosystem in which they occur. Being of little economic importance, however, the family has for the most part failed to arouse keen scientific interest.

The Oosterschelde Estuary: A Case Study of a Changing Ecosystem
ISBN: 9780792328179 / Angielski / Twarda / 624 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The Oosterschelde Estuary is one of the estuaries in the Netherlands which remained after the Delta scheme was completed in 1986. In the Seventies, the Oosterschelde became a national symbol of the change in political thinking and decision-making about the values of our natural environment. As a result of political decision, a storm-surge barrier was built in the mouth of the estuary, as a compromise between safety for the human population and nature conservation.

Proceedings of the Fifth International Symposium on Trichoptera: Lyon, France 21-26 July 1986
ISBN: 9789061936206 / Angielski / Twarda / 397 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. When we offered to host the 5th International Symposium on Trichoptera in Lyon in July 1986, we knew that for us the great Adventure was about to begin. On that July morning in 1983 in Clemson (South Carolina), we could only dimly imagine what the future held in store. One of the worst moment came, in fact, when we were told by th official scientific authorities that no subsidies would be forthcoming. This refusal meant that we would be unable to give any financial help to those colleagues with only modest means at their disposal. Let us hope that the publication of the Proceedings will...

Marine Mammals: Biology and Conservation
ISBN: 9780306465727 / Angielski / Twarda / 630 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The field of marine mammal science has made enormous strides in the last ten years of the 20th century, as well as attracting a large amount of interest, due no doubt to the public appeal of whales, dolphins, and seals, which are never out of media attention. The purpose of this book is to review key topics through chapters on the major disciplines from invited authorities around the world. Subjects covered include evolution and genetics, life histories, ecology, physiology, behaviour, medicine (diseases, parasitology), survey methodology, and all the main conservation issues (pollution,...

Marine, Freshwater, and Wetlands Biodiversity Conservation
ISBN: 9789048174362 / Angielski / Miękka / 399 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Marine, coastal and wetland habitats are threatened, not only through exploitation, but also by the prospect of climate change as ocean currents change course, sea levels rise, and rainfall patterns change. Even the once-common cod is now under threat from the combined effects of over-fishing and a dramatic change-induced decrease in the plankton that cod larvae feed on. Meanwhile, coral reefs remain especially vulnerable to rapid sea-level changes exacerbated by the effects of tourism and disease. This book gathers together a wide range of papers reporting on key research into the...

Lipids in Aquatic Ecosystems
ISBN: 9781441927835 / Angielski / Miękka / 377 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Evidence now suggests that the roles of essential fatty acids as growth promoters and as indices of health and nutrition are fundamentally similar in freshwater and marine ecosystems. Lipids in Aquatic Ecosystems integrates this divergent literature into a coordinated, digestible form. Chapters are organized so as to discuss and synthesize the flow of lipids from lower to higher trophic levels, up to and including humans. Linkages between the production, distribution and pathways of these essential compounds within the various levels of the aquatic food webs, and...

The Dawn of Green: Manchester, Thirlmere, and Modern Environmentalism
ISBN: 9780226720869 / Angielski / Miękka / 248 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Located in the heart of England s Lake District, the placid waters of Thirlmere seem to be the embodiment of pastoral beauty. But under their calm surface lurks the legacy of a nineteenth-century conflict that pitted industrial progress against natural conservation and helped launch the environmental movement as we know it. Purchased by the city of Manchester in the 1870s, Thirlmere was dammed and converted into a reservoir, its water piped one hundred miles south to the burgeoning industrial city and its workforce. This feat of civil engineering and of natural resource diversion inspired one...

Hypoxia in the Northern Gulf of Mexico
ISBN: 9781461425687 / Angielski / Miękka / 284 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Since 1985, scientists have been documenting a hypoxic zone in the Gulf of Mexico each year. The hypoxic zone, an area of low dissolved oxygen that cannot s- port marine life, generally manifests itself in the spring. Since marine species either die or ee the hypoxic zone, the spread of hypoxia reduces the available habitat for marine species, which are important for the ecosystem as well as commercial and recreational shing in the Gulf. Since 2001, the hypoxic zone has averaged 2 1 16,500 km during its peak summer months, an area slightly larger than the state 2 2 of Connecticut, and ranged...

Experimental Watershed Liming Study
ISBN: 9789401066082 / Angielski / Miękka / 248 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This volume is a series of papers summarizing the results of the Experimental Watershed Liming Study (EWLS). The EWLS was initiated in 1989 to investigate the application of calcium carbonate (limestone) to upland and wetland forests as a strategy to mitigate the acidity of lake water and improve fisheries. Woods Lake, in the Adirondack region of New York U. S. A. , is the site of long-term studies of surface water acidification. This whole-ecosystem manipulation was designed to be a comprehensive evaluation of the chemical and biological response of uplands, wetlands and surface waters to...
