| Ocimum selloi is a plant used in traditional medicine as a tea; however, no studies have reported the biological activity of the aqueous extract of this plant. This study aimed to evaluate the cytotoxicity, genotoxicity, and mutagenicity of two concentrations of an aqueous extract prepared by infusion of leaves from O. selloi using the Allium cepa model. The O. selloi infusion contained 107.1 ± 1.27 mg GAE g-1. In the A. cepa test, the concentration of the extract influenced the germination index; for 1.0 mg mL-1, it was 60.78% and for 5.0 mg mL-1, it was 51.14%. The evaluation of root development also showed differences between the two concentrations and the negative control, and differences in mitotic index were observed between the concentrations and... |

| This study aimed at analyzing the influence of different levels of environmental integrity of streams of the Ivinhema river basin (Mato Grosso do Sul State, Brazil) on the diet of A. altiparanae. Samplings were performed from July 2001 to November 2011 at 101 sites, using sieves, seining and gill nets, and electrofishing. Streams were classified into three levels of environmental integrity. We analyzed 664 stomachs with the methods of frequency of occurrence and volumetric analysis index, combined in the Importance Index (AI). The species was omnivorous, with predominance of allochthonous resources. At the least impacted sites, the most representative resource was allochthonous plant material; and in the altered sites in the rainy period the most consumed... |
