Groundwater Ecology and Evolution, Second Edition is designed to meet a multitude of audience needs. The state of the art in the discipline is provided by the articulation of six sections. The first three sections successively carry the reader into the basic attributes of groundwater ecosystems (section 1), the drivers and patterns of biodiversity (section 2), and the roles of organisms in groundwater ecosystems (section 3). The next two sections are devoted to evolutionary processes driving the acquisition of subterranean biological traits (section 4) and the way these traits are differently expressed among groundwater organisms (section 5). Finally, section 6 shows how knowledge acquired among multiple research fields (sections 1 to 5) is used to manage groundwater biodiversity and ecosystem services in the face of future groundwater resource use scenarios. Emphasis on the coherence and prospects of the whole book is given in the introduction and conclusion. Provides a modern synthesis of research dedicated to the study of groundwater biodiversity and ecosystems Bridges the gap between community ecology, evolution, and functional ecology, three research fields that have long been presented isolated from each other Explains how this trans-disciplinary integration of research contributes to understanding and managing of groundwater ecosystem functions Reveals the contribution of groundwater ecology and evolution in solving scientific questions well beyond the frontiers of groundwater systems
