Three vernacular texts from late-13th-century Bohemia, in Middle High German and Old Czech, integrate motifs associated with the Holy Land, pilgrimage and the crusades. The romance Wilhalm von Wenden manifests the late Přemyslids’ royal ideology by portraying an independent, pious ruler who derives authority from Jerusalem. The Alexandreis explores the psychology of a military expedition to provide ground for moral reflection and draws on cartography to exploit the symbolism of Jerusalem’s geographic centrality. The crusade-related details in the Legend of Saint James the Less attest to an informed use of intertextual practices.
The genus Gobio in Italy was represented by the endemic species G. benacensis. The original distribution of this species was the Padano-Venetian district, but since a long time it was introduced in central Italy. Introductions of alien species to Italy during the last 10 years brought the sudden introduction of the Danubian G. gobio. Genetic and morphological analyses revealed the extensive presence of G. gobio, which rapidly colonised several rivers in Italy causing the progressive decline of G. benacensis, which now should be considered as an endangered species. Among examined populations those found in the Tagliamento River and transplanted in the Ombrone River represent genetic reservoirs of this species which will probably disappear in northern Italy.
