VisuaLies: Towards a Classification of Misinfovis Situations
No full textThis paper presents VisuaLies, a workshop designed to engage citizens in identifying misleading information visualisations (Misinfovis). The workshop aims to validate and enhance the Classification of Misinfovis Situations (CMiS), a classification system for lay citizens to spot the formal characteristics of Misinfovis, which we call ‘Misinfovis Situations’. Conducted with participants of varying educational backgrounds, VisuaLies included activities to assess pre-existing knowledge, familiarise with Misinfovis concepts, classify Misinfovis examples and lead to an updated version of CMiS featuring fewer Situations with more accessible language. This study underscores the importance of involving lay people in recognising and describing Misinfovis with their own words to support the development of inclusive knowledge societies. Future iterations of VisuaLies aim to involve diverse audiences and refine feedback collection methods to further enhance the classification’s effectiveness

Heavy metal bioaccumulation in Mytilus galloprovincialis: A transplantation experiment in Venice Lagoon
No full textMussels were transplanted from a marine reference site to a polluted area of the Venice Lagoon to study heavy metal bioaccumulation responses in soft tissues and shells. Soft tissue levels of Mn, Cu, Fe and Cr were initially lower in reference than in lagoon resident mussels, while no differences were observed for Pb and Zn. After one month, the Mn, Cu, Fe and Cr levels in the transplanted mussels increased and overtook both values recorded in resident and marine organisms. Two months after transplantation, metal levels dropped off. At the time of the last sampling, the metal levels seemed to stabilize at lagoon values, except for Cu. Shell levels of Cu, Zn and Pb were lower in mussels from the reference site than in those resident in the lagoon. After three month from transplantation, the bioaccumulation shell data indicated a sharp increase in Mn, Fe and Zn overtaking the levels of lagoon resident bivalves. The results show the usefulness of field transplantation experiments in studying bioaccumulation responses in polluted coastal environments

No full textDemographic responses of the polychaete Dinophilus gyrociliatus to chromium exposure
No full textThe effects of chromium on the life history and demography of Dinophilus gyrociliatus (Polychaeta) were studied on a control and three treated cohorts kept in artificial seawater enriched with nominal concentrations of chromium at 1.0, 1.4, and 1.6 mug/ml. Survival and fecundity were significantly reduced by chromium. Fecundity was higher in the chromium treatments than in the control group at the beginning of the reproductive period; however, overall, the highest fecundity was observed in the control. Life expectancy, net growth rate, and generation time were also significantly reduced by chromium. The population growth rate (lambda) was higher in the treated animals than in the controls. The differences in lambda between the treated animals and the controls (Deltalambda) were almost completely due to the differences in the life tables observed during the first three weeks of life. The differences in survival between the treated and control animals did not contribute to Deltalambda. The contribution to Deltalambda of the slight increase in age-specific fecundity in the early reproductive events compensated for the marked decrease in overall fecundity in the treated animals. The complex effects of chromium enrichment on D. gyrociliatus underline the importance of analyzing both individual and population responses when assessing the effects of pollutants on organisms. Our results confirm that D. gyrociliatus might serve as an indicator species in confined areas of polluted seawater such as lagoons and harbors
