title: Fire severity in slash-and-burn agriculture in southern Brazil: an overview

description: ABSTRACT Slash-and-burn is a traditional agricultural system still widely used in Brazil. The variation in temperature during fires results in different levels of physical, chemical, and biological changes in the soil, which makes it necessarily better to understand the dynamics of fire severity in this system. The aim of this study was to make an analytical comparison of the variation in the temperature reached in the soil during fires in slash-and-burn agriculture. Temperature data were measured in burnt areas with similar fallow times at the following soil depths 0; 2.5 and 5 cm and compared with secondary data from other studies in the same slash-and-burn system in southern Brazil. The peak temperature showed more significant variations in the surface (0 cm) of different soils and different types of regeneration vegetation in each area. Overall, the peak temperatures ranged from 32 to 673 ºC across the three depths. The peak temperature reduction in the 5 cm layer was 88 % compared to the surface and 30 % compared to the 2.5 cm layer. The sandier soils showed greater thermal conductivity at depth. The surface litter seems to exert a more significant influence on the burning severity than the biomass load cut for burning, suggesting that the characteristics of the litter layer on the surface should be better characterized in future studies on fire severity.

title: Ancient origin of Jingchuvirales derived glycoproteins integrated in arthropod genomes

description: Abstract Endogenous virus elements (EVEs) are viral-derived sequences integrated into their host genomes. EVEs of the Jingchuvirales order were detected in a wide range of insect genomes covering several distantly related families. Moreover, Jingchuvirales-derived glycoproteins were recently associated by our group with the origin of a putative new retrovirus based on a glycoprotein captured by a mosquito retrotransposon. But, except for mosquitoes, there is a lack of a more detailed understanding of the endogenization mechanism, timing, and frequency per Jingchuvirales viral lineages. Here we screened Jingchuvirales glycoprotein-derived EVEs (Jg-EVEs) in eukaryotic genomes. We found six distinct endogenization events of Jg-EVEs, that belong to two out of five known Jingchuvirales families (Chuviridae and Natareviridae). For seven arthropod families bearing Jg-EVEs there is no register of bona fide circulating chuvirus infection. Hence, our results show that Jingchuvirales viruses infected or still infect these host families. Although we found abundant evidence of LTR-Gypsy retrotransposons fragments associated with the glycoprotein in Hymenoptera and other insect orders, our results show that the widespread distribution of Jingchuvirales glycoproteins in extant Arhtropods is a result of multiple ancient endogenization events and that these virus fossils are being vertically inherited in Arthropods genomes for millions of years.

title: Subtropical high-montane forest climate refuges in Brazil

description: ABSTRACT Climate change represents one of the greatest threats to global biodiversity. We investigate how climate change will affect the future potential distribution of tree species in subtropical high montane habitats in the Atlantic Forest and identify potential climate refuges for these species. The most frequent and exclusive species in this ecosystem were selected and geographic coordinates were compiled. The maximum entropy algorithm was used for climatic niche modeling. Two scenarios for 2061-2080 were considered for future predictions, one low impact (RCP 4.5) and one high impact (RCP 8.5). Isothermality, mean temperature in the driest quarter, mean temperature in the hottest quarter, rainfall in the driest month, and rainfall in the hottest quarter were the variables that best explained the climatic niche of the majority of species. The areas of potential species occurrence were reduced by 48.37 % (± 13.63 %) (RCP 4.5) and 62.49 % (± 21.87 %) (RCP 8.5) on average. The potential area of Crinodendron brasilense Reitz & L.B.Sm. decreased the most, by 82.11 % (RCP 4.5) and 90.06 % (RCP 8.5), respectively. High elevation areas in the south of Brazil were identified as priorities for conservation to ensure that climate refuges for high montane forest species are maintained in the future. Climate change events may significantly affect the species evaluated in this study.

title: Cyclist mortality in the municipality of São Paulo, Brazil: recent demographic characteristics and trends

description: Abstract Bicycles are a low cost and healthy means of transport, however accidents represent the negative downside. This study sought to describe the characteristics of cyclist deaths, their recent evolution, and the status of the cycle path structure in the city of São Paulo. It involved a descriptive study using information from the Mortality Information System (SIM-DATASUS) between 2000 and 2017. The relationship between the cyclist mortality rate and the cycling path network was evaluated using Pearson’s correlation test. A comparison was made with bicycle journeys in the same period. The sociodemographic profile of deaths was compared with that of the general population. The mortality rate peaked at 7.91/million inhabitants in 2006 and decreased to 1.8/million in 2017; in this period, there was an increase in cycling journeys and in the cycle path structure. A negative correlation was observed between the mortality rate and the cycle path structure. The analysis of deaths indicates a predominantly male, white, young profile, with ≤7 years of schooling; 65% died in collisions with vehicles. There was a decrease in cyclist deaths in the city of São Paulo correlated with the increase in the bicycle path grid from 2008 onwards, in a scenario of increased demand for bicycle transport.

title: Estimation of repeatability and genotypic superiority of elephant grass half-sib families for energy purposes using mixed models

description: ABSTRACT The mixed-model methodology is an alternative to select genotypes for traits highly influenced by the environment. In addition, this method allows FOR estimating the repeatability coefficient and predicting the number of assessments needed for a selection process to increase reliability. This study aimed to determine the minimum number of evaluations necessary for a reliable selection process and to estimate the variance components used for predicting genetic gains between and within half-sib families of elephant grass ( Cenchrus purpureus (Schumach.) Morrone ) using the mixed-model methodology. Half-sib families were generated using genotypes from the Active Germplasm Bank of Elephant Grass. The experiment was performed in a randomized block design with nine half-sib families, three replicates, and eight plants per plot. We evaluated 216 genotypes (individual plants) of elephant grass. The deviance analysis was carried out, genetic parameters were estimated, gains between and within families were predicted, and repeatability coefficients were obtained using Selegen software. There was genetic variability for selection within the families evaluated. The reliability values found above 60 % for plant height and number of tillers and above 80 % for dry matter yield suggest that only two evaluations are required to select superior genotypes with outstanding reliability. Sixteen genotypes were identified and selected for their productive potential, which can be used as parents in elephant grass breeding programs for bioenergy production.

title: The experience of forced sexual intercourse among undergraduate students: associated factors and possible consequences

description: Abstract The scope of this article is to investigate the prevalence of the experience of forced sexual intercourse on life and its possible consequences on mental and sexual health among undergraduate students at a public university in Brazil. It is a quantitative cross-sectional study with 996 undergraduate students. Sampling was carried out systematically by single-stage clusters. Descriptive, bivariate and multivariate analyses were performed using the Poisson Regression model, and the etiological fractions of the consequences of forced sexual intercourse were calculated. The lifetime prevalence of forced sexual intercourse was 12.1%. Female sex, non-heterosexual sexual orientation, first sexual intercourse before the age of 14, child food insecurity and domestic violence were associated with a higher prevalence of the outcome. Individuals who experienced forced sexual intercourse were more likely to be diagnosed with sexually transmitted infections and to represent a potential suicide risk. The study revealed the problems of sexual violence in the university context.

title: Enterovirus infection and its relationship with neurodegenerative diseases

description: Neurodegenerative diseases (NDs) are increasingly common, especially in populations with higher life expectancies. They are associated mainly with protein metabolism and structure changes, leading to neuronal cell death. Viral infections affect these cellular processes and may be involved in the etiology of several neurological illnesses, particularly NDs. Enteroviruses (EVs) frequently infect the central nervous system (CNS), causing neurological disease. Inflammation, disruption of the host autophagy machinery, and deregulation and accumulation/misfolding of proteins are the main alterations observed after infection by an EV. In this perspective, we discuss the most recent findings on the subject, examining the possible role of EVs in the development of NDs, and shedding light on the putative role played by these viruses in developing NDs.

title: Psychosocial Influence Scale of Fruit and Vegetable Consumption among Adolescents: Adaptation and Factorial Validity

description: Abstract Instruments to evaluate psychosocial determinants of fruit and vegetable (F&V) consumption among adolescents are scarce, and there appears to be only one instrument - unnamed and unvalidated - that investigates determinants derived from theories of social psychology targeting the frequency of F&V consumption among adolescents. The scope of this paper was to present the process of cultural adaptation and factor validation of this instrument al-lowing its use in studies with Brazilian adolescents. The cross-cultural adaptation process was accomplished and the final version - named Psychosocial Influence Scale for Fruit and Vegetable Consumption among Adolescents (PSI-FAVES) - was tested with 429 students (58% female) using McDonald’s omega (ω) reliability and Confirmatory Factor Analysis (CFA) as analytical methods. The final version required refinement and the instrument showed adequate overall reliability (ω=0.86) and good fit of the data to the previously elaborated model (CFI=0.955; TLI=0.951 and RMSEA (90%CI) =0.043 (0.038-0.049)), being the first systematically validated instrument to investigate psychosocial determinants of F&V consumption among adolescents.
