The Lichen Genus Usnea On Quercus Suber In Iberian Cork-Oak Forests
2017
AbstractFifteen species of Usnea are recorded from Iberian cork-oak forests: U. ceratina, U. comma, U. dasaea, U. esperantiana, U. flammea, U. fulvoreagens, U. glabrata, U. hirta, U. mutabilis, U. rubicunda, U. subcornuta, U. subfloridana U. subscabrosa, U. substerilis and U. wasmuthii. A key for these species is provided. Details of morphology, chemistry, distribution, ecology and taxonomy are discussed. Usnea dasaea is reported as new to the Iberian Peninsula. New chemotypes of U. fulvoreagens (with squamatic acid) and U. wasmuthii (with psoromic acid) have been identified. Distribution maps of U. dasaeaand U. subcornuta in Europe are presented. A new combination, Usnea subfloridana subsp…
International Vocational Education and Training Research: An Introduction to the Special Issue
2021
The seven articles in this special issue represent a wide range of international comparative and review studies by international research teams from China, Germany, India, Russia, Switzerland and Mexico. The presented projects are part of the national program "Research on the Internationalisation of Vocational Education and Training", funded by the German Federal Ministry of Education and Research (BMBF). An adapted version of Urie Bronfenbrenner���s ecological systems theory forms the conceptual framework of the special issue. The four system levels (micro, meso, exo and macro) are addressed by one article each. The article on the microsystem level focuses on the intended and implemented c…
Propuesta de microrreservas vegetales. Una alternativa para la conservación de líquenes en la comunidad Valenciana.

The Veblen-Gerschenkron Effect of FDI in Mezzogiorno and East Germany
2003
The presence of foreign multinational enterprises (MNEs) can benefit local economies. In particular, if MNEs are very productive compared to domestic firms, they may promote learning and catch-up of local firms. Such a channel of spillovers from MNEs to local firms is known as the Veblen-Geschenkron effect. Rather than the overall density of MNEs in a region or sector, it is their initial productivity advantage on the local firm to determine the positive effect on domestic productivity growth. We test this hypothesis using firm level data for German and Italian companies during the 90's and we find evidence of a significant and robust Veblen-Gerschenkron effect.
Biosynthesis of fungal melanins and their importance for human pathogenic fungi
2003
For more than 40 years fungi have been known to produce pigments known as melanins. Predominantly these have been dihydroxyphenylalanine (DOPA)-melanin and dihydroxynaphthalene (DHN)-melanin. The biochemical and genetical analysis of the biosynthesis pathways have led to the identification of the genes and corresponding enzymes of the pathways. Only recently have both these types of melanin been linked to virulence in some human pathogenic and phytopathogenic fungi. The absence of melanin in human pathogenic and phytopathogenic fungi often leads to a decrease in virulence. In phytopathogenic fungi such as Magnaporthe grisea and Colletotrichum lagenarium, besides other possible functions in …
