Silica phytoliths (microscopic remains originating in plant tissues) have been identified on the enamel surface and dental calculus of a sample of teeth selected from well preserved skeletons from a Late Roman necropolis in Tarragona (Spain). Phytoliths were observed by scanning electron microscopy (SEM) and their siliceous nature was confirmed by X-ray microanalysis. The phytoliths were compared to those of soil samples from both the areas of the tombs corresponding to the abdomen and the periphery of the skeletons, and were classified taxonomically by comparison with a large collection of silica particles from modern plants in the Mediterranean area. Most of the phytoliths identified on the enamel and the dental calculus belong to the family of Poaceae, while the phytoliths from the abdominal area belong to Poaceae, Leguminosae, Cyperaceae, and Chenopodiaceae. Results are concordant with archaeological, ecological, and historical data from the same site, and with the human Mediterranean diet. If done properly, the study of phytoliths can provide direct information about the vegetable diet of past human populations, and could be applied to the study of human fossils.

Con motivo de este quincuagésimo aniversario de la Convención de Patrimonio Mundial, se ha considerado importante realizar una mirada retrospectiva de cómo España empleó la diplomacia cultural para crear redes y alianzas de cooperación tras el bloqueo internacional a la dictadura de Franco. Proceso que siguió tras el periodo denominado de la Transición y el restablecimiento democrático en el cual se realizan los primeros pasos para su ratificación e implementación, con instrumentos necesarios como un nuevo marco legal (la Ley 16/1985 del Patrimonio Histórico Español) y el procedimiento de candidaturas que España presentaría para incorporación a la Lista del Patrimonio Mundial. En esta primera, la lista fase estuvo engrosada por los primeros cincos bienes en inscribirse: la Alhambra de Granada y el Generalife, la Catedral de Burgos, la Mezquita de Córdoba, el Monasterio y Sitio de San Lorenzo de El Escorial y las obras de Antoni Gaudí (el Palau Güell, el Park Güell y la Casa Milà-La Pedrera). Se incluyeron también la Cueva de Altamira, el Acueducto de Segovia, el Conjunto Arquitectónico Prerrománico Asturiano, la Catedral de León, el Museo del Prado y Santo Domingo de Silos, así como el Conjunto Monumental de Santiago de Compostela, la Catedral de Jaén y las Murallas de Ávila.
O artigo tem o objetivo de analisar o turismo cultural na vertente religiosa de forma relacionada à complexidade e a transdisciplinaridade da geografia que se intersecciona com os Jesuítas; ou seja, o Caminho de Inaciano na Espanha onde é o início da Companhia de Jesus e a Rota Iguassu-Misiones entre o Brasil, Paraguai e Argentina onde ocorre a decadência das Missões na América do Sul. A partir deste objetivo, este está estruturado em além da introdução, serão apresentados uma reflexão sobre os conceitos que permeiam este artigo os patrimônios materiais e imateriais destes territórios envolvidos para o desenvolvimento territorial e transfronteiriço. A seguir uma análise comparativa entre estas duas rotas. A metodologia é, complexa, multidisciplinar em territórios distintos que possuem similaridades, singularidades, pelos caminhos e rotas em que o turismo cultural se faz com objetivos de desenvolvimento com as mais distintas redes que podem constituir em cluster de turismo em territórios transfronteiriços.
