The other side of droughts: wet extremes and topography as buffers of negative drought effects in an Amazonian forest. Author(s): ESTEBAN, E. J. L.; CASTILHO, C. V. de; MELGACO, K. L.; COSTA, F. R. C. There is a consensus about negative impacts of droughts in Amazonia. Yet, extreme wet episodes, which are becoming as severe and frequent as droughts, are overlooked and their impacts remain poorly un... ... Repository: BDPA Publication year: 2021
Bulk and rhizosphere bacterial communities of the Caatinga vegetation: drought effects. Author(s): KAVAMURA, V. N.; SANTOS, S. N.; ANDREOTE, F. D.; TAKETANI, R. G.; MELO, I. S. de Repository: BDPA Publication year: 2011
Effects of in vitro drought stress on growth, proline accumulation and antioxidant defense in sugarcane. Author(s): OLIVEIRA, L. A. R. de; CARDOSO, M. N.; OLIVEIRA, A. C. A. de; MACHADO, C. de A.; CARDOSO, B. T.; MUNIZ, A. V. C. da S.; LEDO, A. da S. Drought is the most limiting environmental factor to crop productivity and presents a great variability in the degree of tolerance among and within species, among varieties. The aim of this study was... ... Repository: BDPA Publication year: 2018
Effects of silicon and drought stress on biochemical characteristics of leaves of upland rice cultivars. Author(s): MAUAD, M.; CRUSCIOL, C. A. C.; NASCENTE, A. S.; GRASSI FILHO, H.; LIMA, G. P. P. Silicon (Si) has beneficial effects on many crops, mainly under biotic and abiotic stress. Silicon can affect biochemical, physiological, and photosynthetic processes and, consequently, reduce drought... ... Repository: BDPA Publication year: 2016
The effects of drought on respiration in tropical rainforest. Author(s): MEIR, P.; ROWLAND, L.; COSTA, A. C. L. da; MENCUCCINI, M.; OLIVEIRA, R.; BINKS, O.; VASCONCELOS, S. S.; OLIVEIRA, A. de; SALMON, Y.; FERREIRA, L.; MEIR, P. Repository: BDPA Publication year: 2016
Do chitosan and its derivatives have the same protective effect on drought-contrasting maize genotypes? An analysis of physiological and production processes. Author(s): REIS, C. O. dos; MAGALHAES, P. C.; AMBROSIO, A. dos S.; ALMEIDA, L. G.; CARVALHO, D. T.; SOUZA, T. C, de Water stress is among the most severe abiotic stress factors for maize production. The application of chitosan causes various responses in plants, as a function of its structure and concentration. The... ... Repository: BDPA Publication year: 2022
A spatially distributed hydroeconomic model to assess the effects of drought on land use, farm profits, and agricultural employment. Author(s): MANETA, M. P.; TORRES, M. O.; WALLENDER, W. W.; VOSTI, S.; HOWITT, R.; RODRIGUES, L. N.; BASSOI, L. H.; PANDAY. S. In this paper a high-resolution linked hydroeconomic model is demonstrated for drought conditions in a Brazilian river basin. The economic model of agriculture includes 13 decision variables that can... ... Repository: BDPA Publication year: 2009
Physiological and biochemical changes attenuate the effects of drought on the Cerrado species Vatairea macrocarpa (Benth.) Ducke. Author(s): VIEIRA, E. A.; SILVA, M das G.; MORO, C. F.; LAURA, V. A. Drought is considered the main abiotic stress because it influences the distribution of plant species and limits the productivity of ecosystems. The aim of this study was to evaluate the effects of dr... ... Repository: BDPA Publication year: 2017
Elevated CO2 mitigates the effects of anomalous drought reducing the proportion of abnormal reproductive structures in Arabic coffee. Author(s): MALAGODI-BRAGA, K. S.; MAIA, A. de H. N.; BATISTA, E. R.; RAKOCEVIC, M. The increase in atmospheric carbon dioxide concentration [CO2] results in higher photosynthesis and growth of the upper layer structures in coffee trees. It was hypothesized that coffee trees would in... ... Repository: BDPA Publication year: 2019
Interannual variability of water and heat fluxes in a woodland savanna (Cerrado) in southeastern Brazil: effects of severe drought and soil moisture. Author(s): CONCEIÇÃO, L. F. C. da; ROCHA, H. R. da; NAVARRETE, N. V.; ROSOLEM, R.; CABRAL, O. M. R.; FREITAS, H. C. de Abstract: The Brazilian Cerrado biome is known for its high biodiversity, and the role of groundwater recharge and climate regulation. Anthropogenic influence has harmed the biome, emphasizing the nee... ... Repository: BDPA Publication year: 2024
