Karyotypic conservatism in samples of Characidium cf. zebra (Teleostei, Characiformes, Crenuchidae): physical mapping of ribosomal genes and natural triploidy

Basic and molecular cytogenetic analyses were performed in specimens of Characidium cf. zebra from five collection sites located throughout the Tietê, Paranapanema and Paraguay river basins. The diploid number in specimens from all samples was 2n = 50 with a karyotype composed of 32 metacentric and 18 submetacentric chromosomes in both males and females. Constitutive heterochromatin was present at the centromeric regions of all chromosomes and pair 23, had additional interstitial heterochromatic blocks on its long arms. The nucleolar organizer regions (NORs) were located on the long arms of pair 23, while the 5S rDNA sites were detected in different chromosomes among the studied samples. One specimen from the Alambari river was a natural triploid and had two extra chromosomes, resulting in 2n = 77. The remarkable karyotypic similarity among the specimens of C. cf. zebra suggests a close evolutionary relationship. on the other hand, the distinct patterns of 5S rDNA distribution may be the result of gene flow constraints during their evolutionary history.

Video mapping: um estudo teórico e prático sobre projeção mapeada

The project presents an explanation of the technique of video mapping, resource use, origin and use of the strands. Also conducts multidisciplinary literature review of concepts that can be applied to the technique of video mapping: Augmented Reality, Spatiality in Virtual and Real Environments. The project also introduces aspects of the history of cinema and audiovisual narrative. In addition conducts an inventory of software and hardware required for the technique of video mapping, reports performing experiments with the use of the technique and discusses the results obtained. As a contribution to development area, proposes to use video mapping as an augmented reality tool at an immersive experimental film language
