The aim of this book is to provide an overview of topics related to the extensive geoheritage of hot springs, their natural environments, and their integration into commercial and industrial functions. The eleven chapters explore aspects of historical and cultural traditions, geology and geochemistry, research updates, conservation issues and of course health, wellness, and recreation throughout time. Because natural hot springs and active hydrothermal areas play a significant role in the tourism industry, visitor expectations are examined together with an assessment of common hazards and potential risks in active hydrothermal environments, along with recommendations how to stay safe. For th...
Siliceous hot spring deposits form at Earth's surface above terrestrial hydrothermal systems, which create low-sulphidation epithermal mineral deposits deeper in the crust. Eruption of hot spring waters and precipitation of opal-A create sinter apron complexes and areas of geothermally influenced wetland. These provide habitat for higher plants that may be preserved in situ, by encrustation of their surfaces and permineralization of tissues, creating T0 plant assemblages. In this study, we review the fossil record of hot spring floras from subfossil examples forming in active hot spring areas, via fossil examples from the Cenozoic, Mesozoic and Palaeozoic to the oldest known hot spring flora...

Esta Tesis doctoral comprenden una revisión de las poblaciones termófilas que habitan en algunos Hot Spots de diversidad de América, como lo son el bosque lluvioso Valdiviano en la Patagonia, o los Bosques Nubosos de Costa Rica. También se incluyen ecosistemas extremos como el desierto de Atacama y la Isla Decepción en la Antártica. En este trabajo de tesis se caracterizó la estructura de las comunidades bacterianas en tapetes microbianos de varias termas terrestres diferentes mediante métodos de ecología molecular microbiana, y se midió la relación de los cambios de diversidad con respecto a la temperatura a diferentes escalas espaciales. El filo Cyanobacteria fue identificado co...
This book presents a comprehensive overview of the nature of manifestation and general aspects of thermal springs of Odisha. A detailed description of geological formations and the relationship between tectonic settings with thermal spring emanation is given for better understanding of the geothermal system. Physico-chemical characteristics of water and gas have been studied and interpreted to ascertain the nature and source of geothermal fluid and to generate a conceptual model on the origin. The book can serve as a valuable reference for earth scientists, planners and researchers in the field of geothermal energy. As the thermal springs are spectacular sites for tourists this illustrated book can also help tourists, tourist guides and tourism departments.
Cyanobacteria make a major contribution to world photosynthesis and nitrogen fixation, but are also notorious for causing nuisances such as dense and often toxic `blooms' in lakes and the ocean. The Ecology of Cyanobacteria: Their Diversity in Time and Space is the first book to focus solely on ecological aspects of these organisms. Its twenty-two chapters are written by some thirty authors, who are leading experts in their particular subject. The book begins with an overview of the cyanobacteria - or blue-green algae, for those who are not specialists - then looks at their diversity in the geological record and goes on to describe their ecology in present environments where they play import...
