Available in PDF, EPUB and Kindle. Book excerpt: Nearly one-third of the land area on our planet is classified as arid or desert. Therefore, an understanding of the dynamics of such arid ecosystems is essential to managing those systems in a way that sustains human populations. This second edition of Ecology of Desert Systems provides a clear, extensive guide to the complex interactions involved in these areas. This book details the relationships between abiotic and biotic environments of desert ecosystems, demonstrating to readers how these interactions drive ecological processes. These include plant growth and animal reproductive success, the spatial and temporal distribution of vegetation and animals, and the influence of invasive species and anthropogenic climate change specific to arid systems. Drawing on the extensive experience of its expert authors, Ecology of Desert Systems is an essential guide to arid ecosystems for students looking for an overview of the field, researchers keen to learn how their work fits in to the overall picture, and those involved with environmental management of desert areas. Highlights the complexity of global desert systems in a clear, concise way Reviews the most current issues facing researchers in the field, including the spread of invasive species due to globalized trade, the impact of industrial mining, and climate change Updated and extended to include information on invasive species management, industrial mining impacts, and the current and future role of climate change in desert systems

Book excerpt: Although the Earth's climate system has always been inherently variable, the magnitude and rate of anthropogenic climate change is subjecting ecosystems and the populations that they contain to novel environmental conditions. Because water is the most limiting resource, arid-semiarid ecosystems are likely to be highly responsive to future climate variability. The goal of my dissertation is to understand how precipitation variability affects primary productivity and soil respiration in desert grassland ecosystems. Initially, I reviewed the literature to understand how climate change affects net ecosystem exchange (NEE) across the warm deserts of North America (Chapter 2). Next, I examined the effects of precipitation frequency and intensity on soil moisture (Sk), leaf-level photosynthesis (Anet), predawn leaf water potential (S\pd), aboveground net primary productivity (ANPP), and soil respiration (Rs) (Chapter 3). Last, I studied how large (10 mm) and extreme (30 mm) rainfall events with extended dry periods affected the ecophysiological response of two co-occurring dominant perennial C4 grasses, Bouteloua eriopoda and B. gracilis across an arid-semiarid ecotone (Chapter 4).

Available in PDF, EPUB and Kindle. Book excerpt: Recent invasions of woody plants into semiarid grasslands are a world-wide phenomena with potential ramifications for global-scale carbon cycling. An understanding of how biological and non-biological processes within ecosystems influence water loss to the atmosphere is important to evaluating the consequences of woody plant encroachment on carbon and water cycling in semiarid lands. Accordingly, evapotranspiration in a Chihuahuan Desert grassland was partitioned into its component fluxes for the 2005 summer growing season using a combination of microlysimeters, to quantify soil evaporation, and eddy covariance, to quantify evapotranspiration and net ecosystem exchange of CO2 (NEE). While some of the results of this study (e.g., the ratio of T to ET) are expected to be highly dependent on the particular characteristics of the 2005 summer rainy season, many of them reveal a more general picture about the timing and magnitude of the biological and non-biological water and carbon cycling responses for a warm-season semiarid grassland. This will be important for trying to understand what happens to the carbon and water cycling processes as grasslands are invaded by shrubs.

Available in PDF, EPUB and Kindle. Book excerpt: This volume summarizes our current understanding of biological soil crusts (biocrusts), which are omnipresent in dryland regions. Since they cover the soil surface, they influence, or even control, all surface exchange processes. Being one of the oldest terrestrial communities, biocrusts comprise a high diversity of cyanobacteria, algae, lichens and bryophytes together with uncounted bacteria, and fungi. The authors show that biocrusts are an integral part of dryland ecosystems, stabilizing soils, influencing plant germination and growth, and playing a key role in carbon, nitrogen and water cycling. Initial attempts have been made to use biocrusts as models in ecological theory. On the other hand, biocrusts are endangered by local disruptions and global change, highlighting the need for enhanced recovery methods. This book offers a comprehensive overview of the fascinating field of biocrust research, making it indispensable not only for scientists in this area, but also for land managers, policy makers, and anyone interested in the environment.
