Resumo: Em "O narrador. Reflexões sobre a obra de Nicolai Leskov" (1987a), Walter Benjamin entende que a arte de narrar está em vias de extinção uma vez que o narrador, aquele que reúne em si mesmo o conhecimento do camponês sedentário e do marinheiro comerciante, parece não estar mais entre nós a partir da modernidade. Entretanto, se seguirmos a argumentação de Maria Lugones em "Rumo a um feminismo descolonial" (2014a), que coloca o [des]colonial dentro de uma categoria de não moderno, poderemos considerar que a presença do narrador é perene e se manifesta muitas vezes exatamente no romance, forma literária que Benjamin (1987a) aponta como um indicativo da evolução que vai culminar na morte da narrativa. Em The Distant Marvels (2015), a autora cubana-americana Chantel Acevedo constrói uma protagonista que é a representação literária de um narrador que reúne em si as características benjaminianas e que é, assim, capaz de transmitir experiência. A proposta do presente trabalho é verificar como uma leitura deste romance a partir do viés da descolonialidade pode contribuir para o debate acerca da potência que a intervenção estética feminista tem de contribuir para a construção de novas epistemologias.

Ecological succession is a complex processes involving changes in the structure of plant community and it is an important factor determining the structure of arboreal ants assemblages, but little is known about the effects of succession on ant assemblages in regions of Tropical Dry Forests (TDFs), such as the Brazilian Caatinga. The aim of this study was to investigate the effects of ecological succession on the richness and species composition of arboreal ants in fragments of Caatinga, testing the following hypothesis: i) the richness of arboreal ants increases along a gradient of forest succession, in response to tree richness and/or density; ii) species composition of arboreal ants differs among stages of forest succession due to differences in vegetation structure in theses stages. This study was conducted in 15 plots distributed in three areas with different stages of secondary succession (early, intermediate and late). Tree density and richness were used as surrogate of vegetation structure. Ants were sampled using the technique of beating the foliage and baited pitfall traps, where five trees were sampled per plot, totaling 75 individual trees sampled. We sampled 37 species of ants, distributed in 16 genera and five subfamilies. Ant richness differed among stages of succession and seasons, with higher number of species in the late succession and rainy period, also increasing with tree richness and density. Besides, there was a distinct composition of ant species among stages of succession and seasons. Results obtained in this study reinforce the importance of using ants as environmental bioindicators, since the sensitivity to environmental variations of this group enables us to differentiate early and late successional stages of forest succession in Caatinga environment.
