Marine, Freshwater, and Wetlands Biodiversity
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 biodiversity conservation of these critical and increasingly threatened habitats. Collectively these papers provide a snap-shot of the types of problems they are experiencing, and offer a wealth of topical examples which render this volume especially valuable to teachers of courses in marine, freshwater and wetlands ecology, biological conservation and ecological restoration.
Biosphere Origin and Evolution
The book covers notions by scientists of various branches on the evolutionary relationship between the biosphere and geosphere, evolution features at various levels of living matter organization, and problems of prebiotic evolution and life origin. The data were collected in the course of the RAS program "Biosphere origin and evolution" (subprogram II) in 2003–2006. The objectives of this subprogram were (1) generalization of data related to problems of biosphere origin and evolution accumulated by geneticists, molecular biologists, zoologists, botanists, paleontologists, microbiologists, geologists, chemists, and archaeologists; (2) search for new interdisciplinary approaches to biosphere origin and evolution; (3) development of a "lingua franca" understandable by experts in various fields, which would allow apprehension of results concerning the topic obtained in allied sciences
Bioactive Marine Natural Products
Bioactive Marine Natural Products is the first book available that covers all aspects of bioactive marine natural products. It fills the void in the literature for bioactive marine natural products. The book covers various aspects of marine natural products and it is hoped that all the major classes of bioactive compounds are included. Different classes of marine organisms and the separation and isolation techniques are discussed. The chemistry and biology of marine toxins, peptides, alkaloids, nucleosides and prostanoids are discussed in detail. Biological, toxicological and clinical evaluations are also dealt with to ensure that the book may be adopted at any stage by any practicing organic chemist or biologist, working in academia or in R&D divisions of pharmaceutical companies. Each chapter in the book includes an abstract to highlight the major points discussed in the text and concluding remarks are given. References to books, monographs, review articles and original papers are provided at the end of each chapter.
