Influence of human activities on the distribution of ants of the genus Messor in Pyrénées-Orientales (Hymenoptera: Formicidae: Myrmicinae). - Based on the distribution of the genus Messor in Pyrénées-Orientales (France), a study of the distribution and geographical structure of the genus is presented, accompanied by a discussion of the process of dispersal over the ages. These ants have a diet strictly composed of seeds, the availability of which influences their establishment. A link between the historical development of human agriculture, characterized by concomitant displacement of cultivated and messicole plants, and the geographic distribution of Messor ants is suggested in this study.

Tourism as a world culture phenomenon furthers the discovery of various aspects and manifestations of culture. The cultural tourism allows the familiarization with and illustration of the historical development of various civilizations throughout the centuries and the achievements in the various fields of human activities. The tourist travel activates cognitive, informative, communicational and evaluating functions of perception of reality at the place of destination. Each travel brings a new knowledge and a touch to an alien social cultural environment; each tourist, even at a subconscious level, performs a comparative analysis of the alien and of their own culture. Cultural tourism furthers the knowledge, study and comparison of the cultural heritage. The more unique, authentic and valuable it is, the greater is the power of attraction of the corresponding tourism destination. Apart and independent from the expert’s evaluation of the cultural heritage qualities and features, its value is influenced also by the nature of tourists’ expectations. Therefore from a tourism point of view the greater these expectations are, the higher is the evaluation of the cultural heritage of the corresponding destination.

AbstractThis paper is divided into two sections. The first section presents a concise survey of the intellectual itinerary of the French sociologist Pierre Bourdieu in the French intellectual field. Then, after a short presentation of Bourdieu’s The Social Structures of the Economy, I proceed to a broader discussion of his economic sociology. After a presentation of Bourdieu’s key conceptual contributions, I question some aspects of Bourdieusian sociology with regard to its ambition of historicising the ‘economic field’. I identify the limitations of this historicising project in the extension of the metaphor of the market to virtually all fields of human activities and in a concept of capital which fails to grasp a social relation specific to the historical development of capitalism.

Abstract— A new species, Espeletia ocetana (Asteraceae), from about 3500 m a. s. l. in Páramo de Ocetá, Mongua, Boyacá department, Colombia, is described and illustrated. The new species exhibits a caulescent rosette habit (0.7‐1.8 m tall), sessile leaves, elliptic leaf laminae with greyish indumentum, robust bracteate thyrsoid capitulescences spreading laterally from rosette, each holding 16‐37(‐69) capitula, external phyllaries 14.2‐31.1 mm long, and ray florets 13.9‐21.3 mm long arranged in 2.0‐2.9 series. It is markedly different from the majority of other members of the genus, and only slightly similar to E. jaramilloi, from which it can be easily distinguished by its taller stems, wider leaves with a smaller length/width ratio, and longer sheaths. Furthermore, E. ocetana has capitula with ray florets arranged in fewer series, and with longer phyllaries, ray corollas, ray corolla limbs, ray styles, ray style branches, disc florets, and disc styles. In addition, E. ocetana is distributed allopatrically in regard to E. jaramilloi, and differs as well in its ecological preference for humid to very humid shrubby páramos. Espeletia ocetana is rather abundant in its type locality, which is a relatively well-conserved páramo located within the limits of Parque Natural Regional Siscunsí-Ocetá. However, it is absent from road margins, abandoned agriculture fields, and other areas impacted by human activities. Further studies will be necessary to know appropriately the extent of the geographic distribution of E. ocetana, its ecological requirements and its phylogenetic affinities with other species.
