| In the present report, we investigate polymorphism in three of the Brazilian species of Chauliognathus Hentz, 1930 (Coleoptera, Cantharidae), by analyzing the geographical color pattern variation of the elytra in C. flavipes, C. fallax and C. octomaculatus. These species belong to the mullerian complex called the "yellow-black". They are usually found in clusters on their host plants at various locations and present similarities in the external body morphology and in the color pattern of the elytra and the pronotum. Chauliognathus flavipes is the most common species with eight phenotypic classes followed by of C. fallax and C. octomaculatus with six and two phenotypic classes respectively. The analyses indicate a statistically significant difference in the... |

| The Floripa H and L rat lines, selected for high and low locomotion in the central aversive area of an open field, a widely used emotionality test, were proposed as a model for studying the genetic basis of anxiety. The present study aimed to verify if the QTL Ofil1, mapped to rat chromosome 4 and previously identified as being related to emotionality in another population of rats, contributes to the behavioral variability observed in the Floripa rat lines. To this purpose, rats of five generations of selective breeding were genotyped for two polymorphic markers, D4RAT59 and D4MGH27, flanking Ofil1. Changes in genotype and allele frequencies throughout generations were evaluated in both H and L lines, in order to assess if the bidirectional selection based... |
