Produktbeschreibung

A murmur is heard from the depths of time. Life and Earth are engaged in a dialog that has lasted for four billion years. Sometimes it's a whisper, sometimes a roar. One part sometimes gets the upper hand, dominates the discussion and sets the agenda. But mostly the two have some kind of mutual understanding, and the murmur goes on. Most of us don't listen. Nora does. She listens, and she tries to understand. Nora Noffke has focused her scientific career on the interaction between the living and the non-living. This is no mean task in an academic world where you are usually either this or that, such as either a biologist or a geologist. The amount of stuff you need to grasp is so large that it usually feels better to sit comfortably on one chair, rather than to risk falling between them. Geobiology is not for the faint of heart. Nora's focus is on that all-important biological substance mucus, or EPS (ext- cellular polymeric substance). EPS is the oil in the machinery, the freeway to travel for many small animals and protists, the coat of armour for others, the mortar in the brick wall for yet others. For microbes such as cyanobacteria it may be the world they built, the world they live, eat, fight, multiply, and die in.

Rezensionen

From the reviews:

"This book is therefore most welcome, also because it has been written by one of the few top researchers in this field covering both geology and biology ... . a text book for students or a reference work for specialists. The book might serve as both ... and it will serve well. ... The book ends with an 8-page list of references and an 18-page (!) well thought-over index. ... In general, the figures are well chosen. ... Conclusion: worth to be bought ... ." (A. J. van Loon, Geologos, Vol. 16 (4), 2010)

"Nora Noffke has produced an excellent text book covering a relatively recently developed field - the study of microbial mats in shallow water environments. ... The book is well laid out and the text is clear and well-written ... . Noffke has a fluid style that is a pleasure to read. ... I recommend it to both the general reader, as a good introduction to MISS, and to the dedicated student of MISS in the geological record." (Frances Westall, Geological Magazine, February, 2011)

"Noffke's book provides a state-of-the-art perspective on an important line of geobiological research ... . As geobiologists and astrobiologists think about how to apply and sharpen the tools afforded by MISS, we can be thankful that Nora Noffke has provided us with a detailed but accessible road map for continuing research." (Andrew H. Knoll, Astrobiology, Vol. 11 (1), 2011)

"Nora Noffke deals systematically with ... microbially-induced sedimentary structures on Earth, both in the modern environment, and in fossil deposits of all ages. ... Extensively referenced and laid out in a logical and methodical manner, the reader is provided with all the information they need to understand the concepts, and this is communicated in a clear and friendly way. ... To an interested layperson, with no prior knowledge of microbiology ... the book contains all they need to know to gain a thorough understanding." (Leila Battison, Astrobiology Society of Britain, September, 2010)
