Impossible Fictions in the Romantic NovelIn the Romantic period, the novel is regarded as a literary form that, by poetological necessity, makes experiments by means of literary representation possible. Seen in an European perspective this is almost solely a matter of early German Romanticism, Frühromantik, where Friedrich Schlegel and Novalis by formulating the novel as a specific, modern genre, try to state a new, revolutionary aesthetics. The article thus points at three characteristic features of the novel’s poetics within this context: 1) the novel contains a double poetics of formal heterogeneity and spiritual homogeneity; 2) the novel gets its value through its inherent epistemology of world views; 3) the novel of early German Romanticism understands itself in a productive split of an utopian vision that never can be fulfilled and an auto-reflexivity exactly because of the knowledge of permanent unfulfillment. Further,the article argues, an aesthetics of impossible fictions evolves as the potential and heritage of this kind of poetics. In the last part of the article, a novel of the Swedish (post-)Romantic author Carl Jonas Love Almqvist (1793-1866), Drottningens juvelsmycke (The Queen’s Tiara, 1834), is read as way of representing, through the constitution of the main character, Tintomara, a principle of the absolute that displays the borders of novelistic representation

Biotic and abiotic factors investigated in two <i>Drosophila </i>species – evidence of both negative and positive effects of interactions on performance

Multiple environmental factors acting in concert can interact and strongly influence population fitness and ecosystem composition. Studies investigating interactions usually involve only two environmental factors; most frequently a chemical and another abiotic factor such as a stressful temperature. Here we investigate the effects of three environmental factors: temperature, an insecticide (dimethoate) and interspecific co-occurrence. We expose two naturally co-occurring species of Drosophila (D. hydei and D. melanogaster) to the different environments during development and examine the consequences on several performance measures. Results are highly species and trait specific with evidence of two- and three-way interactions in approximately 30% of all cases, suggesting that additive effects of combined environmental factors are most common, and that interactions are not universal. To provide more informative descriptions of complex interactions we implemented re-conceptualised definitions of synergism and antagonism. We found approximately equal proportions of synergistic and antagonistic interactions in both species, however the effects of interactions on performance differed between the two. Furthermore, we found negative impacts on performance in only 60% of interactions, thus our study also reveals a high proportion of cases with positive effects of interactions
