| Human development activities as water reservoir construction have great impact on the vegetation, thus changing its floristic, as well as its structure and ecology functions. Parana Pine Forest alongside with grasslands have been highly modified and in particular to the last one, there are few works related to its restoration. In the border of Irai water reservoir (Metropolitan Region of Curitiba, PR), where occurs grasslands associated to the Parana Pine Forest, where it were establishedtree plantations aiming rescue tree vegetation lost due to the flooding. Inside these plantations, an experiment was established to compare growth and survival of eight local native species in 12 months, in single species plots and under the same environmental conditions.... |

| Dung beetles (Coleoptera, Scarabaeinae) attracted to sheep dung in exotic pastures. In this study we provide data on the abundance and richness of dung beetles (Coleoptera, Scarabaeidae, Scarabaeinae) attracted to sheep dung in exotic pastures (Brachiaria spp.). In four areas of exotic pasture pitfall traps were installed and baited with fresh sheep dung for sampling of dung beetles. A total of 2,290 individuals were captured belonging to 16 species, 10 genera and five tribes of Scarabaeinae beetles. Trichillum externepunctatum Preudhomme de Borre, 1886 and Dichotomius bos (Blanchard, 1843) were dominant. The guild of dwellers was the most abundant in pastures. We demonstrate that dung beetles are attracted to sheep dung. Since the production of both... |

| Chemical studies of the plant family Annonaceae have intensified in the last several decades due to the discovery of annonaceous molecules with medicinal potential (e.g., benzylisoquinoline alkaloids and acetogenins). Approximately 500 alkaloids have been identified in 138 Annonaceae species in 43 genera. In addition, until 2004, 593 annonaceous acetogenins (ACGs) had been identified, from 51 species in 13 genera.This suggests that plants from this family allocate important resources to the biosynthesis of these compounds. Despite the diversity of these molecules, their biological roles, including their physiological and/or ecological functions, are not well understood. In this study, it was provided new data describing the variety and distribution of... |
