This study aimed to assess the effect of thermal-hydraulic variables in female buffaloes with or without direct solar exposure in a year of strong El Niño through behavior responses and infrared thermography to reinforce the environmental comfort indicators, in Marajó Island, Pará, Brazil. The experiment was carried out in Cachoeira do Arari municipality and 20 female Murrah buffaloes were randomly assigned to two groups: Group WS (n = 10) was kept in pickets with native trees. Group NS (n = 10) was kept in crush squeeze with no shade. Data on air temperature (AT, °C), relative air humidity (RH, %), wind velocity (WV, m/s), rectal temperature (RT), respiratory rate (RR), and body surface temperature (BST) were collected. Practical Buffalo Comfort Climatic Condition Index (BCCCI), practical Buffalo Environmental Comfort Index (BECI), Temperature and Humidity Index (THI) and Benezra's Thermal Comfort Index (BTCI) were obtained. Infrared thermography analysis was carried out with a FLIR T-series T640bx camera. Data on time spent grazing, ruminating, idleness, and in other activities were recorded. A significant difference in AT of ~1°C was found between the groups at 6 a.m., 10 a.m. and 6 p.m. THI indicated emergency conditions. Female buffaloes were at danger PBCCCI conditions at 2 p.m. There was also significant difference for RT between treatments at 10 a.m., 2 p.m. and 6 p.m., whose values were higher (P < 0.05) for animals from NS Group, with the highest mean time at 2 p.m. Pearson correlation was significant and positive (P < 0.01) between RT mean and VUL, TI and ORB mean, maximum and minimum temperatures. The total time given to grazing was 518.2 min for the group NS and 629.5 min for the group WS. Rumination was more pronounced in the afternoon shift for the group NS. Buffaloes kept in a system with trees graze, ruminate and perform other activities with more intensity than animals raised in systems without access to shade, and tend to hyperthermia, mainly at 10 a.m. and 2 p.m., in Marajó Island, Pará, Brazil.

Abstract - The objective of this work was to evaluate the phenolic composition of wine from 'Cabernet Sauvignon' (Vitis vinifera) grapes subjected to leaf removal management at different timing, in a high-altitude region. The experiment was carried out in the 2015 and 2016 vintages, in a vineyard located in the municipality of São Joaquim, in the state of Santa Catarina, Brazil. The treatments consisted of different periods of leaf removal in the clusters, at five phenological stages ? full bloom, buckshot berries, pea-sized berries, veraison, and 15 days after veraison ?, and of a control without leaf removal. At harvest, 50 kg of each treatment were collected for winemaking. The contents of gallic acid, catechin, p-coumaric acid, vanillic acid, resveratrol, quercetin, rutin, and kaempferol were evaluated. The results showed the importance of leaf removal before veraison, to obtain wine with a higher concentration of phenolic compounds, which favors wine quality. The leaf removal management promotes the increase of gallic acid, vanillic acid, p-coumaric acid, resveratrol, quercetin, and kaempferol in wine. The early leaf removal before veraison results in increases in vanillic acid, p-coumaric acid, resveratrol, quercetin, and kaempferol. The wine made from grapes not subjected to leaf removal shows higher values of catechin and rutin. Resumo - O objetivo deste trabalho foi avaliar a composição fenólica de vinho elaborado com uvas 'Cabernet Sauvignon' (Vitis vinifera) submetidas ao manejo de desfolha em várias épocas, em região de elevada altitude. O experimento foi conduzido nas safras de 2015 e 2016, em um vinhedo localizado no munícipio de São Joaquim, no estado de Santa Catarina, Brasil. Os tratamentos consistiram de diferentes épocas de desfolhas na região dos cachos, em cinco estádios fenológicos ? plena florada, baga-chumbinho, baga-ervilha, mudança de cor das bagas (véraison) e 15 dias após o véraison ?, e de um controle sem desfolha. Na fase da colheita, 50 kg de uvas de cada tratamento foram colhidos para a elaboração do vinho. Avaliaram-se as concentrações de ácido gálico, catequina, ácido p-cumárico, ácido vanílico, resveratrol, quercetina, rutina e campferol. Os resultados evidenciaram a importância do manejo precoce da desfolha antes do estágio de véraison, para a obtenção de vinho com maior conteúdo de compostos fenólicos, benéficos à qualidade do vinho. O manejo da desfolha promove o aumento de ácido gálico, ácido vanílico, ácido p-coumárico, resveratrol, quercetina e campferol no vinho. A desfolha precoce antes do estágio de véraison resulta em aumento de ácido vanílico, ácido p-coumárico, resveratrol, quercetina e campferol. O vinho elaborado com uvas não submetidas ao manejo da desfolha apresenta valores superiores de catequina e rutina.
