[Entrevista com Carla Simone Rodeghero e Clarissa Sommer Alves]
No full textO Programa de Educação Patrimonial (PEP) é fruto de uma exitosa parceria entre o Departamento de História da Universidade Federal do Rio Grande do Sul (UFRGS) e o Arquivo Público do Estado do Rio Grande do Sul (Apers). A iniciativa começou em 2008, a partir de um projeto de extensão que passou a incorporar diversas ações vinculadas à educação patrimonial. Além de promover a difusão arquivística através de oficinas para estudantes da educação básica, o PEP também capacita graduandos de história e oferece cursos de formação para professores sobre os usos possíveis do acervo da instituição arquivística e dos seus espaços para produção do conhecimento. Calcada na conscientização sobre a importância do patrimônio cultural arquivístico e no debate de temas sensíveis para a sociedade brasileira, a iniciativa já levou ao Apers quase 16 mil estudantes. Nessa entrevista, conversamos com as condutoras do programa, a professora doutora Carla Simone Rodeghero, titular da UFRGS, e a historiadora Clarissa Sommer Alves, mestre em História e analista em assuntos culturais do Apers

Compatibility counts: MHC-associated mate choice in a wild promiscuous primate
No full textThe mechanisms and temporal aspects of mate choice according to genetic constitution are still puzzling. Recent studies indicate that fitness is positively related to diversity in immune genes (MHC). Both sexes should therefore choose mates of high genetic quality and/or compatibility. However, studies addressing the role of MHC diversity in pre- and post-copulatory mate choice decisions in wild-living animals are few. We investigated the impact of MHC constitution and of neutral microsatellite variability on pre- and post-copulatory mate choice in both sexes in a wild population of a promiscuous primate, the grey mouse lemur (
Microcebus murinus
). There was no support for pre-copulatory male or female mate choice, but our data indicate post-copulatory mate choice that is associated with genetic constitution. Fathers had a higher number of MHC supertypes different from those of the mother than randomly assigned males. Fathers also had a higher amino acid distance to the females' MHC as well as a higher total number of MHC supertypes and a higher degree of microsatellite heterozygosity than randomly assigned males. Female cryptic choice may be the underlying mechanism that operates towards an optimization of the genetic constitution of offspring. This is the first study that provides support for the importance of the MHC constitution in post-copulatory mate choice in non-human primates
Are there Ubiquitous Parasite-driven Major Histocompatibility Complex Selection Mechanisms in Gray Mouse Lemurs?
No full textColonel Jaroslav Sommer, the fate of an ordinary soldier affected by two dictatorships
No full textBachelor Thesis "Colonel Jaroslav Sommer, the fate of an ordinary soldier effected by two dictatorships " attempt to descibe the lifestory of Colonel Jaroslav Sommer with use of comparison method of secondary literature and thorough Archive research. Author based on family information reveals the story of his relative Jaroslava Sommer, who fought in the Second World War in the West. His actions in the Czechoslovak army are so interesting that it certainly deserve attention and detailed historical research. The thesis focuses on Jaroslava Sommers life milestones, that are placed in historical context. By using the obtained materials leads to the conclusion that the key factor that significantly influenced Sommers life, was joining to foreign resistance. Especially his stay in the West, which was the pretense for his departure from the army and the subsequent persecution by the communist regime, can be regarded as decisive. The theme of the thesis is rewarding not only from the perspective of a specific family history, but also allows us to open up issues concerning contemporary context. The fate of one soldier helps bring complicated phase of czechoslovakian, but also international history in the first half of the twentieth century

No full textLandscape-level comparison of genetic diversity and differentiation in a small mammal inhabiting different fragmented landscapes of the Brazilian Atlantic Forest
No full textHabitat loss and fragmentation can have detrimental effects on all levels of biodiversity, including genetic variation. Most studies that investigate genetic effects of habitat loss and fragmentation focus on analysing genetic data from a single landscape. However, our understanding of habitat loss effects on landscape-wide patterns of biodiversity would benefit from studies that are based on quantitative comparisons among multiple study landscapes. Here, we use such a landscape-level study design to compare genetic variation in the forest-specialist marsupial Marmosops incanus from four 10,000-hectare Atlantic forest landscapes which differ in the amount of their remaining native forest cover (86, 49, 31, 11 %). Additionally, we used a model selection framework to evaluate the influence of patch characteristics on genetic variation within each landscape. We genotyped 529 individuals with 12 microsatellites to statistically compare estimates of genetic diversity and genetic differentiation in populations inhabiting different forest patches within the landscapes. Our study indicates that before the extinction of the specialist species (here in the 11 % landscape) genetic diversity is significantly reduced in the 31 % landscape, while genetic differentiation is significantly higher in the 49 and 31 % landscapes compared to the 86 % landscape. Results further provide evidence for non-proportional responses of genetic diversity and differentiation to increasing habitat loss, and suggest that local patch isolation impacts gene flow and genetic connectivity only in the 31 % landscape. These results have high relevance for analysing landscape genetic relationships and emphasize the importance of landscape-level study designs for understanding habitat loss effects on all levels of biodiversity
