 Author(s): MARKEWITZ, D.; FIGUEIREDO, R. de O.; DAVIDSON, E. A. The objective of this study was to investigate the role of dissolved CO2 (H2CO3*) as a mechanism of cation removal from surface soils under secondary land uses in the tropics. Soil leachate columns we... ... |
 Author(s): OLIVEIRA, V. R. de; RIBEIRO, A.; PAREYN, F. G. C.; DRUMOND, M. A.; PORTO, D. D.; KIILL, L. H. P.; FERRAZ FILHO, A. C. Managed Caatinga forests in Northeast Brazil are an important source of wood products, however, successful regeneration and regrowth is important to guarantee sustainability in these forests. The main... ... |
 Author(s): AMORIM, L. B.; SALCEDO, I. H.; PAREYN, F. G. C.; ALVAREZ, I. A. Tropical dry forests (TDFs) are being deforested at unprecedented rates. The slash/burn/ agriculture/fallow-extensive livestock sequence causes significant nutrient losses and soil degradation. Our ai... ... |
 Author(s): EBERHARDT, I. D. R.; SCHULTZ, B.; RIZZI, R.; SANCHES, I. D.; FORMAGGIO, A. R.; ATZBERGER, C.; MELLO, M. P.; IMMITZER, M.; TRABAQUINI, K.; LUIZ, A. J. B.; FOSCHIERA, W. Abstract: The potential of optical remote sensing data to identify, map and monitor croplands is well recognized. However, clouds strongly limit the usefulness of optical imagery for these application... ... |

Abstract: Cloud cover is the main issue to consider when remote sensing images are used to identify, map and monitor croplands, especially over the summer season (October to March in Brazi). This pape... ... |
 Author(s): NEGRÓN-JUÁREZ, R. I.; HOLM, J. A.; FAYBISHENKO, B.; MAGNABOSCO-MARRA, D.; FISHER, R. A.; SHUMAN, J. K.; ARAUJO, A. C. de; RILEY, W. J.; CHAMBERS, J. Q. Forest disturbance and regrowth are key processes in forest dynamics, but detailed information on these processes is difficult to obtain in remote forests such as the Amazon. We used chronosequences o... ... |
 Author(s): ALVES, D. S.; BATISTELLA, M.; LINHARES, C. A. Deforestation in the Brazilian Amazon has produced fragmentation of the largest tropical rain forest in the planet resulting in impacts over biodiversity and the functioning of ecosystems. Most of the... ... |
 Author(s): SOARES, F. M.; PIRES, L. F.; SANTOS, L. O. B. da S.; CALHAU, R. F.; MACULAN, B. C. M. dos S.; COYLE, K.; WANG, S.; FOLMER, E.; DRUCKER, D. P.; CAMPOS, M. L. de A.; MARCONDES, C.

This paper explores the design and creation of metadata schemas based on the FAIR Data Principles. We provide a clear interpretation of these principles, focusing on how they apply to metada... ... |
 Author(s): WOODS, W.; REBELLATO, L.; TEIXEIRA, W. G.; FALCÃO, N. P. S. Amazonian soils are almost universally thought of as extremely forbidding. However, it is now clear that complex societies with large, sedentary populations were present for over a millenium before Eu... ... |
