Influence of fire prevention management strategies on the diversity of butterfly fauna in the eastern Pyrenees

Fire prevention management is becoming a necessity in many Mediterranean locations to regulate fire of natural or human origin. However, very few studies have determined the real effects of the strategies adopted on local fauna. Butterflies are sensitive to local changes and they can thus serve as indicators of environmental changes. Three different types of fire prevention management approaches in three different localities in the Eastern Pyrenees (France) were performed and the butterfly community composition was investigated. We show that of the 80 species of butterflies observed, 36 % can be considered as biological markers. An original objective treatment of data using hierarchical distance analysis combined with a neural network analysis (Self-Organizing Maps) was applied in this study. Our conclusions are that the overall number of species is maintained independently of the fire prevention type but that some important changes are observed among butterfly communities, with a clear reduction of the numbers of endemic/specialized species in favour of generalist ones for the two most drastic fire prevention management approaches studied here. The influence of such approaches is discussed on the basis of the conservation of Mediterranean species of Lepidoptera

Genetic structure analysis of Eufriesea violacea (Hymenoptera, Apidae) populations from southern Brazilian Atlantic rainforest remnants

Random amplified polymorphic DNA (RAPD) markers were used to analyze the genetic structure of Eufriesea violacea populations in three fragments (85.47, 832.58 and 2800 ha) of Atlantic rainforest located in the north of the Brazilian state of Paraná. A total of twelve primers produced 206 loci, of which 129 were polymorphic (95% criterion). The proportions of polymorphic loci in each population ranged from 57.28% to 59.2%, revealing very similar levels of genetic variability in the groups of bees from each fragment. Unbiased genetic distances between groups ranged from 0.0171 to 0.0284, the smallest genetic distance occurring between bees from the two larger fragments. These results suggest that the E. violacea populations from the three fragments have maintained themselves genetically similar to native populations of this species originally present in northern Paraná

Narrative and rhetorical approaches to problems of education: Jerome Bruner and Kenneth Burke revisited

Over the last few decades there has been a strong narrative turn within the humanities and social sciences in general and educational studies in particular. Especially Jerome Bruner’s theory of narrative as a specific ‘mode of knowing’ was very important for this growing body of work. To understand how the narrative mode works Bruner proposes to study narratives ‘at their far reach’ – as an art form – and on several occasions he refers to the dramatistic pentad as an important method for ‘unpacking’ narratives. The pentad proposed by Bruner to study narratives was developed by the American philosopher and rhetorician Kenneth Burke and is embedded in his general linguistic theory of dramatism. From an educational perspective Bruner’s reference to the work of Burke has not been elaborated upon thus far. In this paper we aim to take Bruner’s suggestion at hand and explore how his educational theory of narrative as a mode of knowing can indeed be enriched by Kenneth Burke’s theory and method of dramatism. We claim that specifically the rhetorical framework that is developed by dramatism offers an important perspective about perspectives for education in a context that is increasingly confronted with a plurality of interpretive frameworks
