| PRODES is completing almost thirty years of uninterrupted monitoring of clear-cut deforestation over the Brazilian Amazon. Until now, no estimate of its mapping accuracy has been made. In this sense, this article brings a first approximation of mapping accuracy estimation of PRODES deforested areas, taking as example the state of Mato Grosso for the year 2014. For this, a random sampling panel was constructed, stratified with two strata, the deforestation of 2014 and the remaining forest. The sample size was calculated using the binomial function. In addition, a web platform was built to evaluate the points drawn by three independent evaluators. The global accuracy of the mapping of deforestation for the state of Mato Grosso, for the year 2014 was 94.5%,... |

| Photochemical responses are directly dependent on the level of incident solar radiation during the initial establishment of forest species. The aim of the current study was to evaluate chlorophyll a fluorescence in 2-year-old Bertholletia excelsa seedlings from July to October 2017. Samples were acclimated on polyolefin screens under different quantitative (35%, 50%, 65% and 80%) and qualitative (thermo-reflective, red, blue and green screens, at 50% solar radiation attenuation) shading levels and under full sun at the 77th, 105th, 122nd and 150th days after acclimation - DAA - (73 days) in Sinop County - MT. Estimates of effective quantum yield (ΦPSII) and electron transport rate (ETR) were performed in the OS5p Fluorometer (150 μmol m-2... |
