The state of Pará, located in the Amazon region of Brazil, has observed in recent years an increase in cocoa (Theobroma cacao) cultivation and has become the largest producer in Brazil. Due to its physiological characteristics, cacao is cultivated in native forests understory or under the shade produced by fast-growing native tree species, serving as an important species for restoration of degraded areas. However, mapping and monitoring cocoa plantation using optical sensor images is a challenge given its botanical and arboreal characteristics that can be confused with other native species at various stages of secondary regrowth. Agroforestry systems are important components of sustainable production in the Amazon and our work sought to better describe the evolution of cocoa plantations in terms of their historical expansion, farming properties practices, land use transitions and fire regimes. Our findings to analyze the relationships between cocoa plantations and hotspots, data from the INPE?s reference satellite between the years 2004 to 2020 were used in this study, polygons classified as cocoa areas, generated by the MapCacau research project, were used, in a total of 69,904 hectares distributed throughout the state of Pará. Finally, we used the protected areas? official limits in the State of Pará to analyze the plantations? occurrence in regions in discordance with environmental legislation. The data show that cocoa-producing properties are statistically fewer than non-producing properties, as well as having lower deforestation rates. In our study, we observed that 52,778 hectares (88.87%) of the cocoa area planted had already been deforested by the year 2008?the threshold of deforestation defined by Brazil?s Forest Code. It was also possible to verify that approximately 20,900 hectares continue to be mapped as forest by PRODES, despite our field data identifying cocoa plantations shaded by explored forest in these areas. Regarding the crop?s formation, the data show a tendency to convert pasture areas to cocoa plantations, proving that cocoa farming expansion in the State of Pará is an important activity for degraded areas recovery and not a main driver of deforestation. The finding that cocoa plantations are still classified as forest by PRODES and project TerraClass highlights the difficulty of mapping this crop using orbital images in a traditional way. Through this paper, it was possible to observe that due to the typical characteristics of perennial crops (cocoa), fire points showed a significant reduction in the mapped areas, highlighting that the expansion of cocoa plantations in the state of Pará contributed to soil protection, to the reduction of greenhouse gas emissions into, in addition to contributing to the generation of jobs and revenue. Finally, we found about 99.54% of the cacao plantations in the State of Pará are located outside of any preservation area, indigenous land or quilombola settlement.

Resumo: A maioria das pesquisas para diagnóstico e avaliação da lentiviroses se baseia na identificação, direta ou indireta, da proteína viral no sangue, leite, sêmen, saliva ou tecidos. Trabalhos com proteômica avaliando as lentiviroses são escassos. A princípio, a análise, detecção e/ou avaliação do vírus são realizadas a partir, principalmente, de amostras de sangue, sendo a maioria dos estudos realizados relacionada ao HIV. O perfil proteico do plasma seminal de pequenos ruminantes associado com índices reprodutivos já foi determinado, mas trabalhos correlacionando a presença dessas proteínas no sêmen à Artrite Encefalite Caprina (CAE) são escassos. Na primeira fase desse trabalho foi avaliada a atividade das metaloproteinases (MMPs) no sangue por meio da zimografia (eletroforese unidimensional) e, na segunda fase, o trabalho objetivou analisar o perfil proteico do plasma seminal de caprinos soropositivos cronicamente para a CAE e identificar proteínas presentes no plasma seminal relacionadas com a enfermidade que possam ser utilizadas no futuro como possíveis marcadores da doença. Para tanto, foi realizada a eletroforese bidimensional em gel de poliacrilamida (2D-PAGE) e espectrometria de massa de amostras de plasma seminal de reprodutores soropositivos crônicos para a CAE. A zimografia mostrou alta atividade das MMPs (MMP-2 e MMP-9) no grupo soropositivo. A avaliação seminal mostrou não haver diferença estatística para os parâmetros volume, motilidade e vigor (respectivamente, 0,97A ± 0,61; 82,78A ± 7,52; 3,89A ± 0,58) entre grupos; porém existente para a concentração espermática (4,22B ± 0,71). A análise bidimensional dos géis mostrou grande número de spots em ambos os grupos avaliados, porém com maior número nos animais soropositivos. A cronicidade da CAE em reprodutores caprinos pode ter sido a responsável pela maior expressão e atividade das proteínas no sangue (MMP-2 e pro-MMP-2) e plasma seminal. A espectrometria de massa permitiu identificar no plasma seminal proteínas de resposta imune, relacionadas, possivelmente, ao quadro crônico da doença. Abstract: The most research for diagnosis and evaluation of lentiviruses are based on the identification (direct or indirect) of the viral protein in the blood, milk, semen, saliva or tissues. Works with proteomics evaluating lentiviruses are scarce. At first, virus's analysis, detection and assessment are made from mainly blood samples, most of the studies related to HIV. Studies have conducted the protein profile of seminal plasma of small ruminants associating with reproductive parameters but works correlating the presence of these proteins in the semen with Caprine Arthritis Encephalitis (CAE) are scarce. The first phase of this work aimed to evaluate the activity of matrix metalloproteinases (MMPs) in the blood by zymography (1DPAGE). In the second phase, the study aimed to analyze the protein profile of seropositive CAE goats and to identify proteins related with the disease that may be used as markers in the future. Two-dimensional electrophoresis and mass spectrometry was used on samples of seropositive goat bucks chronically infected with CAE. The zymography showed high activity of MMPs (MMP-2 and MMP-9) in the seropositive group. Semen evaluation showed no difference with volume, motility and vigor parameters (respectively, 0.97A ± 0.61; 82.78A ± 7.52; 3.89A ± 0.58); however, there was significant difference of sperm concentration between groups (4.22B ± 0.71). The two-dimensional analysis revealed a great number of spots in both groups, however there was a higher number in seropositive animals. CAE chronicity in bucks may have been responsible for greater expression and activity of proteins in seminal plasma. Mass spectrometry allowed the identification of immune response proteins in seminal plasma, possibly related to the chronic state of the disease.
