Biocrust-forming cyanobacteria inoculation to restore degraded soils from dryland ecosystems
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 cianobact...
Introducción al Análisis Espacial de Datos en Ecología y Ciencias Ambientales
El presente libro pretende estimular el interés sobre la dimensión espacial de los datos ecológicos, así como la utilización de técnicas apropiadas para tenerla en cuenta a la hora de analizarlos y modelizarlos. Esta consideración es especialmente importante para mejorar nuestro conocimiento sobre el funcionamiento del mundo que nos rodea, así como para gestionarlo de una manera acorde a sus características ecológicas intrínsecas.

Fictions of Well-Being
In late medieval and early modern Spain, physicians began to translate and refashion medical information for lay readers. This book explores the concept of the sickly reader, a highly motivated individual whom medical writers encouraged to seek out useful remedies and efficacious hygienic practices in various vernacular health guides.
Soil Protists
Protists are by far the most diverse and abundant eukaryotes in soils. Nevertheless, very little is known about individual representatives, the diversity and community composition and ecological functioning of these important organisms. For instance, soil protists are commonly lumped into a single functional unit, i.e. bacterivores. This work tackles missing knowledge gaps on soil protists and common misconceptions using multi-methodological approaches including cultivation, microcosm experiments and environmental sequencing. In a first part, several new species and genera of amoeboid protists are described showing their immense unknown diversity. In the second part, the enormous complexity of soil protists communities is highlighted using cultivation- and sequence-based approaches. In the third part, the present of diverse mycophagous and nematophagous protists are shown in functional studies on cultivated taxa and their environmental importance supported by sequence-based approaches. This work is just a start for a promising future of soil Protistology that is likely to find other important roles of these diverse organisms.
The Spanish Connection
In early modern times, the city of Seville was the most important entrept̥ between the Old and the New World, attracting numerous merchants from all of Europe. They provided the American market with European merchandise, especially with textiles and metalware from Flanders and France. This book investigates the networks of Flemish and French merchants in Seville, displaying overall structures of trade as well as collective strategies of both merchant colonies.
