Book Description
The word ‘fluid’ describes a phenomenon as well as a material property. Of special interest is how aspects of fluidity influence the active and direct handling of materials and how its special characteristics are expressed in experimental practices and thinking patterns. The motivation for focusing on fluidity as a prerequisite for ‘becoming’ and the nature of processes originated from the art-based ‘Liquid Things’ research project. As this subject covers a very wide spectrum, the approach was modified to allow the participation of several disciplines; the book draws on the philosophy of science, hydrodynamics, and the cultural sciences, and focuses on the role of fluidity in cognitive and experience processes with the aim of establishing a grammar of ‘movable’ materials.

Book Description
The ongoing growth of human populations within US coastal regions continues to increase habitat loss, eutrophication, organic loading, overfishing, and other anthropogenic stressors in estuarine waters. The National Estuarine Research Reserve System (NERRS) is a federally funded initiative that addresses these critical estuarine problems and coastal resource issues at 25 sites in 21 states. Now estuarine and watershed scientists, resource managers, community planners, and other professionals dealing with coastal zone issues have an expert resource describing the NERRS program, organization, goals, and management strategy. Estuarine Research, Monitoring, and Restoration first defines the components and technical aspects of the NERRS program, then provides valuable insight into the program through the presentation of six case studies of NERRS sites. This book examines estuarine problems including degraded water quality, reduction of biodiversity, and problematic invasive species, then analyzes the human impacts affecting estuaries. The comprehensive analysis of the six estuarine reserve locations characterizes each region's physical, chemical, and biological conditions from the perspective of the NERRS program. These case studies include a cross section of sites from three coasts, each study emphasizing the importance of unified efforts of government and citizens to successfully maintain the ecology of these critical areas.

Book Description
In arid lands, where vegetation is sparse or absent, the open ground is not bare but generally covered by a community of small, highly specialized organisms. Cyanobacteria, algae, microfungi, lichens, and bryophytes aggregate soil particles to form a coherent skin - the biological soil crust. It stabilizes and protects the soil surface from erosion by wind and water, influences water runoff and infiltration, and contributes nitrogen and carbon to desert soils. Soil surface disturbance, such as heavy livestock grazing, human trampling or off-road vehicles, breaks up the fragile soil crust, thus compromising its stability, structure, and productivity. This book is the first synthesis of the biology of soil crusts and their importance as an ecosystem component. Composition and functioning of different soil-crust types are discussed, and case studies are used to show the impact of crusts on landscape hydrology, soil stability, nutrient cycles, and land management.
