| ABSTRACT The use of traps is extremely important in several types of ecological studies, and may assist in the capture of individuals in areas that are difficult to access. In the present study, we compared the effectiveness of wooden (Schramm) versus "Tomahawk" traps to capture Salvator merianae (Duméril & Bibron, 1839) lizards. The study was conducted in Eldorado do Sul, Rio Grande do Sul, Brazil. Field data were collected from August 2013 to March 2015, during the reproductive period of the species. The study involved two types of baited traps: i) "Tomahawk", made of galvanized steel; and ii) Schramm, a wooden trap. The capture rate of the Schramm wooden traps was 1.63 individuals/day, and of the "Tomahawk" was 0.36 individuals/day. These results... |

| To assess the extent of genetic variability of rDNA intergenic spacer (IGS) in Metarhizium sp., 34 strains (27 isolated in Brazil) were sequenced and analyzed together with an additional 20 Metarhizium anisopliae var. anisopliae sequences retrieved from GenBank. Overall, the global nucleotide diversity for the region under study was of 0.090, while for the Brazilian isolates it was only 0.016. Phylogenetic analyses showed four well-supported groups (A, B, C, and D), one of which (D) has not been previously identified. All but one of the Brazilian strains cluster in this novel D phylogroup, suggesting that the genetic variation found in Brazil is a subset of the worldwide M. anisopiliae var. anisopliae variation. |

| The discovery and characterization of informative intraspecific genetic markers is fundamental for evolutionary and conservation genetics studies. Here, we used nuclear ribosomal ITS sequences to access intraspecific genetic diversity in 23 species of the genus Passiflora L. Some degree of variation was detected in 21 of these. The Passiflora and Decaloba (DC.) Rchb. subgenera showed significant differences in the sizes of the two ITS regions and in GC content, which can be related to reproductive characteristics of species in these subgenera. Furthermore, clear geographical patterns in the spatial distribution of sequence types were identified in six species. The results indicate that ITS may be a useful tool for the evaluation of intraspecific genetic... |
