The construction of the Three Gorges Reservoir,from impoundment of the Changjiang(Yangtze) River,China,may have affected native fish species. Thus,the status of two lotic freshwater fish species,Coreius heterodon and C.guichenoti,were monitored in the Three Gorges Reservoir,including fish abundance,individual composition,growth,condition,and mortality. Data on both species were gathered from upstream,midstream and downstream areas of the reservoir and,where available,from studies published before and after dam construction. Lower abundance,slower growth,a less diversified age structure,poorer fish condition(indicated by hepatosomatic index) and higher mortalities were recorded in sites nearest the dam compared with upstream areas. Furthermore,after final impoundment,individual Coreius species inhabiting the area changed,with young individuals becoming more abundant,while upstream of the reservoir the two Coreius species became smaller at a given age. The results show that the status of the two Coreius species was subject to dramatic changes after impoundment.展开更多

Gone were the post-war years, and with them the autarchy, poverty and famine, characteristics of that time. After a transitory fifties decade, the country entered a prosperous time, which is known as the develompentism sixties--desarrollismo. The franscoism itself promoted this change. Meanwhile, it became a mandatory to guide the population so the fostered modem life did not imply, among other issues, an abandonment of the traditional gender order. Popular cinema played a key role in that objective. Particularly tourism narratives had direct implications on the renewed way to understand gender identities. In this article we will approach two blockbusters, as representative examples of the mainstream films productions, through which analyse how masculinity and femininity were screened and considered.展开更多
