Plant form is a product of emergent processes of cell division, patterning and morphogenesis. These fundamental processes remain poorly characterised in plants. However, engineering approaches can provide new tools and frameworks for the study and manipulation of plant development. This dissertat...

Se estudiaron teórica y experimentalmente dos familias de polioxometalatos de valencia mixta 3d0/3d1 y 4d0/4d1. La primera corresponde a una familia de polimetoxohexavanadatos de tipo Lindqvist (familia V6). La segunda familia (4d0/4d1) corresponde a fosfo-dodecamolibdatos (familia PMo12). El an...

Two families of mixed-valence polyoxometalates of the 3d0/3d1and 4d0/4d1 type were studied, both, theoretical and experimental. The first family corresponds to a polyoxohexavanadates of the Lindqvist type (V6). The second, (4d0/4d1), corresponds to a phospho-dodecamolybdate family (PMo12). The ...

Una importante α-hidroxicetona utilizada como precursor en la industria farmacéutica en la síntesis de fármacos con propiedades α y β adrenérgicas es el (R)-fenilacetilcarbinol, R-PAC. La producción de R-PAC usando la levadura Saccharomyces cerevisiae, glucosa y benzaldehído, fue el primer proces...

An important α-hydroxy ketone used as precursor in the pharmaceutical industry is (R)-phenylacetylcarbinol or R-PAC. It is used in the synthesis of drugs with α and β adrenergic properties. The production R-PAC using the yeast Saccharomyces cerevisiae, glucose and benzaldehyde was the first chira...

El tamaño de puesta en aves se encuentra determinado por la cantidad y variabilidad de los recursos y de las condiciones ambientales como el clima y la presión de depredación. Sin embargo, se desconoce si es que algunos rasgos de historia de vida influyen en que el tamaño de puesta varíe diferenc...

Clutch size in birds depends on the variation of resources and the environmental conditions as climate and predation pressure. However, the factors influencing on the differences of this variation among species are not clear. In this thesis, I assess if the kind of nest, diet specialization and s...

Several studies, using both molecular and ecological evidence, confirm that rafting contributes to population connectivity and range expansion of many species. However, there is also indication that the effectiveness of rafting transport of species to establish in new habitats...

This dissertation focuses on understanding the metabolic flexibility of a thermoacidophilic crenarchaeote, the mechanisms underlying its physiology, and the consequences for its ecology. Acidianus strain DS80 was isolated from an acidic spring in Yellowstone National Park (YNP) and displays versa...
