Análise e distribuição espacial do potencial para a sustentabilidade no pós-pandemia do COVID-19 nos municípios do Rio Grande do Sul

A pandemia causada pelo coronavírus disparou a possibilidade da crise em diversos segmentos, sobretudo com a adoção do isolamento social, principal ação para o controle da doença infectocontagiosa. O presente estudo justifica-se pela preocupação em relação às tendências do desenvolvimento sustentável no pós-pandemia da COVID-19, no estado do Rio Grande do Sul. A mensuração do grau de sustentabilidade dos municípios segue a tese de que, quanto maior for o grau de sustentabilidade dos municípios, menor o impacto da pandemia, e maiores os recursos para restabelecer o equilíbrio. O objetivo da pesquisa é analisar a distribuição espacial do potencial para a sustentabilidade no pós-pandemia do COVID-19, nos municípios do Rio Grande do Sul, a fim de gerar um mapa de risco sobre os municípios com menor e maior potencial para a sustentabilidade no pós-pandemia. Foi realizada uma análise ecológica, aplicado o instrumento Barômetro da Sustentabilidade, realizada a distribuição e análise espacial, utilizando o cálculo do Índice de Moran. Os resultados apresentam a distribuição e análise espacial do número de casos confirmados, coeficiente de incidência e quantitativo de óbitos pela COVID-19 no Estado. A espacialidade pode explicar o coeficiente de incidência da doença. Foi estimado o potencial para a sustentabilidade e gerado o mapa de risco do potencial para a sustentabilidade, no pós-pandemia do COVID-19, para os municípios do Rio Grande do Sul. Spatial analysis and distribution of the potential for sustainability in the post-pandemic of COVID-19 in the municipalities of Rio Grande do Sul A B S T R A C TThe pandemic caused by the coronavirus triggered the possibility of the crisis in several segments, especially with the adoption of social isolation, the main action for the control of the infectious disease, therefore, the present study is justified by the concern in relation to the trends of sustainable development in the post-pandemic of COVID-19, in the state of Rio Grande do Sul. Measuring the degree of sustainability of the municipalities follows the thesis that the greater the degree of sustainability of the municipalities, the less the impact of the pandemic, and the greater the resources to restore balance. The objective of the research is to analyze the spatial distribution of the potential for sustainability in the post-pandemic of COVID-19, in the municipalities of Rio Grande do Sul, in order to generate a risk map with less and greater potential for sustainability in the post- pandemic. This study was carried out by means of an ecological analysis and application of the Barometer of sustainability, later the distribution and spatial analysis was carried out by means of the Moran Index. The spatial analysis, performed by calculating the Moran Index, showed significant spatial independence for confirmed cases (I = 0.058; p = 0.024) and deaths (I = 0.032; p = 0.039), and a significant, albeit weak, correlation. for the incidence coefficient (I = 0.234; p = 0.001) of COVID-19. Spatiality does not explain the distribution of cases and deaths. However, when taking into account the population size of the municipalities, in relation to the number of cases, expressed by the incidence coefficient, the spatial aggregation gains merit. The potential for sustainability was estimated and the risk map of the potential for sustainability was generated, in the post-pandemic of COVID-19, for the municipalities of Rio Grande do Sul.Keywords: Moran index; Sustainability Barometer; Sustainability Index; coronavirus; Pandemic.

Effect of animation and review video making (arvima) in non-classical learning model on independent learning and students’ learning outcome

The non-classical learning model used in this study was a jigsaw type cooperative learning model with the assignment treatment of making learning material video which is expected to make it easier in finding knowledge in teaching materials, with the creativity of students’ forming skills. The purpose of this study are to determine: (a) the effect of animation video and review video making in non-classical learning model on the ability to learn independently of students of the chemistry education study program at USN Kolaka, (b) the effect of animation video and review video making in non-classical learning model on the ability of spatial independence of students in the chemistry education study program at USN Kolaka, and (c) the effect of animation video and review video making in non-classical learning model on the learning outcome of students in the chemistry education study program at USN Kolaka. This research was a quasi-experimental research (quasy experiment) with a posttest only research design. The research population was students in the IV and VI semester of Chemistry Education Study Program. The instrument used was a questionnaire of learning independence, spatial ability and learning outcome.

Compositional turnover in ecto- and endoparasite assemblages of an African bat, Miniopterus natalensis (Chiroptera, Miniopteridae): effects of hierarchical scale and host sex

We studied the compositional turnover in infracommunities and component communities of ecto- and endoparasites infesting a bat, Miniopterus natalensis (Chiroptera, Miniopteridae), across seven sampling sites using the zeta diversity metric (measuring similarity between multiple communities) and calculating zeta decline and retention rate (both scales) and zeta decay (component communities). We asked whether the patterns of zeta diversity differ between (a) infracommunities and component communities; (b) ecto- and endoparasites and (c) subsets of communities infecting male and female bats. The pattern of compositional turnover differed between infracommunities and component communities in endoparasites only. The shape of zeta decline for infracommunities indicated that there were approximately equal probabilities of ecto- and endoparasitic species to occur on/in any bat individual within a site. The shape of zeta decline for component communities suggested the stochasticity of ectoparasite turnover, whereas the turnover of endoparasites was driven by niche-based processes. Compositional turnover in component communities of ectoparasites was more spatially dependent than that of endoparasites. Spatial independence of compositional turnover in endoparasites was due to subcommunities harboured by female bats. We conclude that the patterns of compositional turnover in infracommunities were similar in ecto- and endoparasites, whereas the patterns of turnover in component communities differed between these groups.

Producing randomness between plots in pepper and snap bean experiments

It is important to know the production variability among experimental plots in a protected environment because this information reduces error and increases the reliability of the results. Therefore, the objective of this study was to characterize the spatial independence of fruit yield between plots of peppers and snap beans. Data on production uniformity were gathered from trials performed at the Department of Plant Science, Federal University of Santa Maria. Different plots sizes were created according to the number of plants in the crop row. To verify the randomness of the data distribution, we applied a sequence test between the plots within one line for individual and combined harvests. The use of ten plants per plot in experiments with peppers led to no randomness within the lines during the production of fruit fresh biomass. In experiments with snap beans conducted in a greenhouse, a plastic tunnel and by unprotected cultivation using plots with six or more basic units, 12 or more plants per plot produced random fresh biomass data for fruits within the crop row.

Stochastically driven adult–recruit associations of tree species on Barro Colorado Island

The spatial placement of recruits around adult conspecifics represents the accumulated outcome of several pattern-forming processes and mechanisms such as primary and secondary seed dispersal, habitat associations or Janzen–Connell effects. Studying the adult–recruit relationship should therefore allow the derivation of specific hypotheses on the processes shaping population and community dynamics. We analysed adult–recruit associations for 65 tree species taken from six censuses of the 50 ha neotropical forest plot on Barro Colorado Island (BCI), Panama. We used point pattern analysis to test, at a range of neighbourhood scales, for spatial independence between recruits and adults, to assess the strength and type of departure from independence, and its relationship with species properties. Positive associations expected to prevail due to dispersal limitation occurred only in 16% of all cases; instead a majority of species showed spatial independence (≈73%). Independence described the placement of recruits around conspecific adults in good approximation, although we found weak and noisy signals of species properties related to seed dispersal. We hypothesize that spatial mechanisms with strong stochastic components such as animal seed dispersal overpower the pattern-forming effects of dispersal limitation, density dependence and habitat association, or that some of the pattern-forming processes cancel out each other.
