En las zonas áridas, la acción combinada del cambio climático y el aumento de la presión humana están causando una degradación acelerada de los ecosistemas. En este contexto, es necesario investigar nuevas estrategias de restauración que nos permitan mejorar las acciones de restauración en estas zonas. Para ello, en esta tesis se exploró el uso de biocostras, comunidades de organismos que colonizan los primeros centímetros del suelo y que viven en estrecha asociación con las partículas del suelo, para la recuperación de suelos degradados en ecosistemas áridos. De entre todos sus componentes, se investigó el potencial uso restaurador de la inoculación con especies de cianobacterias formadoras de biocostras, pues son los organismos que más potencial presentan para restaurar zonas áridas debido a sus condiciones fisiológicas adaptadas a ambientes extremos y su facilidad para ser aisladas y cultivadas ex situ. En concreto, se evaluó la viabilidad de diferentes especies nativas de cianobacterias para promover el desarrollo de una nueva biocostra que mejore las condiciones de los suelos degradados de zonas áridas, así como estrategias para la reducción del estrés ambiental en condiciones de campo. Los resultados de esta tesis constituyen un avance significativo en el uso de esta tecnología para recuperar suelos afectados por la degradación en ecosistemas áridos.

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.

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

Los descubrimientos de esta tesis implican un avance en nuestro conocimiento de las comunidades de cianobacterias del sudeste español y un uso óptimo de cepas clave para restaurar suelos degradados mediante su inoculación. En primer lugar, se han identificado las especies de cianobacterias que colonizan las biocostras de la región más árida de Europa, aportando información valiosa con relación a su morfología y distribución. Esto es de interés para ampliar nuestra comprensión de las dinámicas de sucesión de las biocostras de estas zonas y sus efectos en las funciones del suelo. Además, se ha secuenciado el gen 16S del rRNA de las cepas aisladas, aumentando así la información existente en las bases de datos genéticas públicas, lo que apoyará futuras identificaciones de cianobacterias. También se han analizado las comunidades de cianobacterias de biocostras en sitios con distinto nivel de degradación, contribuyendo a la identificación de especies que puedan ser más resistentes a la degradación y, por tanto, candidatas interesantes para ser utilizadas en la restauración de suelos degradados. Así mismo, en esta tesis se demuestra que es posible optimizar la producción de biomasa de cianobacterias usando medios elaborados a partir de fertilizantes agrícolas, lo que convierte la inoculación de suelos con cianobacterias en una estrategia más rentable y aplicable en ensayos de restauración a gran escala. Además, el éxito de la inoculación en laboratorio de suelos de regiones semiáridas del Mediterráneo, las cuales son muy vulnerables a la degradación, pone de manifiesto el potencial de la aplicación de esta técnica en estas zonas. Nuestros resultados muestran la capacidad de N. commune de mejorar las propiedades del suelo, especialmente el contenido en carbono orgánico, después de inocular distintos tipos de suelos con diferentes niveles de degradación. También revelan la importancia de analizar la comunidad indígena del suelo antes de inocular para planificar una restauración con éxito. Por último, los resultados de esta tesis sientan la base para aplicar este método de forma más exitosa y eficiente a escala de campo.

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.

The global environment is constantly changing and our planet is getting warmer at an unprecedented rate. The study of the carbon cycle, and soil respiration, is a very active area of research internationally because of its relationship to climate change. It is crucial for our understanding of ecosystem functions from plot levels to global scales. Although a great deal of literature on soil respiration has been accumulated in the past several years, the material has not yet been synthesized into one place until now. This book synthesizes the already published research findings and presents the fundamentals of this subject. Including information on global carbon cycling, climate changes, ecosystem productivity, crop production, and soil fertility, this book will be of interest to scientists, researchers, and students across many disciplines. - A key reference for the scientific community on global climate change, ecosystem studies, and soil ecology - Describes the myriad ways that soils respire and how this activity influences the environment - Covers a breadth of topics ranging from methodology to comparative analyses of different ecosystem types - The first existing "treatise" on the subject
