Biochar has been proposed as a soil amendment to reclaim salt-affected ***,the evaluation of the different biochar types in these soils is essential due to the significant variation among biochar *** this study,biochars from sugarcane bagasse(SB),orange bagasse(OB),and corncob(CB)were applied alone and in the presence of gypsum(G)to test their potential to remediate a highly degraded saline-sodic soil in Brazil´s Northeast *** that,we conducted a laboratory column-leaching experiment and a greenhouse *** the column-leaching test,we analyzed the sodium adsorption ratio(SAR),the electrical conductivity of the saturation extract(ECe),the concentrations of major ions,and the exchangeable sodium percentage(ESP).Maize plants were grown in the leached soil in a ***-and corncob-derived biochars were more efficient than gypsum in reducing the soil salinity,bringing the indicators below threshold values,and optimizing soil reclamation *** ECe,SAR,and ESP were reduced to 3.42 dS m−1,1.64(mmolc dm−3)0.5 and 4.86%,respectively,in the SB treatment;and to 3.19 dS m−1,0.88(mmolc dm−3)0.5 and 2.53%,respectively,in the CB *** bagasse biochar did not effectively reduce the salinity *** biochar treatments improved seed germination and plant *** SB,CB,SBG,and CBG treatments increased plant height(478–558%),shoot mass(783–983%),and root mass(386–500%),***,the application of SB and CB is an effective alternative to remediate saline-sodic soils and to reduce the impact of soil salinity in the environment.

Hydrological variability and long-term floristic-structural modifications in different habitats of a tropical semi-deciduous forest

Shifts in hydrological regimes alter river flow rates and flood pulses, decrease environmental heterogeneity and the floristic-structural complexity of associated plant communities. We tested the hypothesis that drought events affect plant community composition and structure at a small-scale within a riparian fragment towards a reduction in floristic-structural complexity. The tree community was sampled in three habitats (wet, transitional and dry) and monitored in seven inventories carried out between 1991 and 2018. Hydrological variations were evaluated through annual rainfalls, river flow rates and water level data. The species richness and the detrended correspondence analysis axes were used to characterise the temporal modifications in floristic composition. Community structure was described in terms of biomass: accumulated, growth of survivors, mortality and recruitment. Generalised linear mixed models were fitted to evaluate the effects of time and environment in community. It was concluded that the climate has become drier in recent years due to declining precipitation that has affected flow rates and water levels. The floristic-structural complexity of the study fragment was maintained during the monitoring period. However, prolonged and extreme drought events displayed the potential to impact floristic-structural patterns.

作者： Diego santos Vieira de jesus ESPM-Rio Rio de JaneiroBrazil

The aim of the article is to analyse the creative queer spaces of Gustavo Vinagre’s movie New Dubai. The mainargument indicates that gay sex creatively brings the possibility of resistance against gentrification and questionsheteronormative rules in the organization of society and space. Sex and the violence of the interventions in thecontext of the real estate speculation point to the violence and voyeurism of filming, especially of filming sex.
