Disturbances, elevation, topography and spatial proximity drive vegetation patterns along an altitudinal gradient of a top biodiversity hotspot

The correlation between vegetation patterns (species distribution and richness) and altitudinal variation has been widely reported for tropical forests, thereby providing theoretical basis for biodiversity conservation. However, this relationship may have been oversimplified, as many other factors may influence vegetation patterns, such as disturbances, topography and geographic distance. Considering these other factors, our primary question was: is there a vegetation pattern associated with substantial altitudinal variation (10-1,093 m a.s.l.) in the Atlantic Rainforest-a top hotspot for biodiversity conservation-and, if so, what are the main factors driving this pattern? We addressed this question by sampling 11 1-ha plots, applying multivariate methods, correlations and variance partitioning. The Restinga (forest on sandbanks along the coastal plains of Brazil) and a lowland area that was selectively logged 40 years ago were floristically isolated from the other plots. The maximum species richness (>200 spp. per hectare) occurred at approximately 350 m a.s.l. (submontane forest). Gaps, multiple stemmed trees, average elevation and the standard deviation of the slope significantly affected the vegetation pattern. Spatial proximity also influenced the vegetation pattern as a structuring environmental variable or via dispersal constraints. Our results clarify, for the first time, the key variables that drive species distribution and richness across a large altitudinal range within the Atlantic Rainforest. © 2013 Springer Science+Business Media Dordrecht.

Subtitling as a pedagogical tool for language teaching in journalism

This study was designed to present and discuss some results produced by a research involving the use of English subtitles of some news videos from the webiste Reuters.com (http://www.reuters.com) with pedagogical reasons in a Brazilian context (Academic English for Journalism). We have developed the research during two semesters at UNESP (Universidade Estadual Paulista Júlio de Mesquita Filho). The professor in charge of the study has chosen the students of Journalism as the audience to whom the videos were presented. The assumptions of many theorists and experts in Audiovisual Translation were adopted as our Theoretical Sources. The first step of the study was the assessment of the syllabus of each course. This was very helpful as a guidance in order to choose the most relevant and interesting videos for students. After the evaluation of academic and professional interests, we chose some videos to insert appropriate subtitles, according to some strategies suggested by Panayota Georgakopoulou and Henrik Gottlieb. Finally we presented the videos during the English classes. At the first time, they were presented without subtitles just to notice the comprehension level of the students. After that, the videos were presented with English subtitles. As we first assumed, the students haven’t had the whole comprehension of specific details during the first presentation, they have just used their previous knowledge and the visual aids to help them in a superficial understanding of the news. As the subtitles appear, the process of communication was finally accomplished.

New Business Models And Editorial Exemption: A Study On Service Journalism Based On Ecommerce Operations

The paper presents and discusses business strategies based on the association from journalistic content to new commercial practices in digital media. We describe selected examples from Folha de S. Paulo and El País involving service guides, links and ecommerce advertisements. The employed method provides content analysis to illustrate how the search for new business models in journalism may conduct its commercial activities beyond the conventional sale of advertising and subscriptions, including a discussion on the challenges and implications of this practice. The hypothesis is demonstrated by describing operations for the sale of tickets, books, music, and films related to news features and service journalism contents. The text finally wonders and discusses how such commercial actions may affect editorial autonomy and publishing exemption.
