Extreme weather events often cause canopy disturbance and litter deposition. To study the CO2-fixing bacterial response to forest damage, we simulated damage caused by extreme with four different treatments: control (CN), trimming + removal of branches leaves debris (TR), retaining (TD), undamaged transplantation (UD). We used cbbL gene, which encodes ribulose-1,5-biphosphate carboxylase/oxygenase (RubisCO), for Miseq sequencing analyze dynamics community composition soil bacteria five consecutive years after damage. Double treatments litterfall inputs (TD) facilitate restoration better than single (TR or UD). Most are facultative autotrophic bacteria, Nitrosospira, Streptomyces, Saccharomonospora main carbon-fixing microorganisms, have significant differences during damaged canopy. The ecosystem lasted 4–5 years. Rainfall pH showed a negative correlation most communities. This provides theoretical basis improving carbon sequestration capacity also guidance management.

The in-situ quantification of turbulent flux and evapotranspiration (ET) is necessary to monitor crop performance in stressful environments. Although cacti can withstand conditions, plant responses plant-environment interactions remain unclear. Hence, the objective our study was investigate interannual seasonal behaviour components surface energy balance, environmental morphophysiological parameters, biomass yield water relations a Nopalea cochenillifera semi-arid region Brazil. data were collected from micrometeorological tower between 2015 2017. results demonstrate that net radiation significantly higher during wet season. Latent heat not significant season dry During dry-wet transition particular, sensible than other seasons. We observed large decline soil There no difference ET or seasons; however, there 40% reduction transition. seasons wet-dry showed lowest Evaporative Stress Index. plants high cladode content evaluation period. In conclusion, these findings indicate rates growth, explain response cactus regarding partitioning ET.

Northeast Brazil (NEB), particularly its semiarid region, represents an area highly susceptible to the impacts of climate change, including severe droughts, and intense anthropogenic activities. These stresses may be accelerating environmental degradation desertification soil in NEB. The main aim this study was gain geospatial insights into biophysical parameters surface energy balance actual evapotranspiration on a multi-temporal scale, aiming detect analyze spectral behavioral patterns areas vulnerable processes, based thematic maps at surface, for NEB mainly region from 2000 2019. Geospatial data 8-day MODIS sensor products were used, such as reflectance (Terra/MOD09A1 Aqua/MYD09A1), temperature (Terra/MOD11A2 Aqua/MYD11A2), (Terra/MOD16A2 Aqua/MYD16A2), version 6. Therefore, study, pixel-to-pixel values processed by calculating average pixel statistics each year. From product, digital processing albedo vegetation indices also carried out, using computational programming scripts machine learning algorithms developed via Google Earth Engine (GEE) platform. presents seasonal analysis these components their relationships over 20 years. Through statistical correlations, new predictive model developed. quantitative spatiotemporal assessed through descriptive statistics, measures central tendency dispersion, error analyses correlation indices.

AbstractIn semi-arid regions, is necessary to explore strategies mitigate abiotic stresses such as water deficit and salinity. This study aimed evaluate the stress tolerance capacity of three species subjected different regimes salinity levels, based on dry matter production use efficiency (WUE). The Handroanthus impetiginosus, Vachellia farnesiana, Amburana cearensis were evaluated in combination with (50%, 75%, 100% reference evapotranspiration – ET0) levels (0.18, 1.50, 1.90 dS m−1). results show that biomass accumulation increased at 50% 75% ET0, while WUE decreased ET0. level (1.90 m−1) caused reductions leaf (LDB), total (TDB), LDB/TDB ratio, WUE. negative effects high plant height greater application highest was obtained ET0 for A. H. V. farnesiana exhibited (2.58 g) (0.21 g L−1). Overall, can tolerate drought conditions, being sensitive concentrations during their initial growth.NOVELTY STATEMENTThe Caatinga characterized by low availability soil salinization. Therefore, assessing ability native cope these conditions allows utilization reforestation programs salinity-exposed environments. Studies combined factors are scarce. indicated albeit some NaCl concentrations.
