TL;DR: The periods between the beginning and ending of the maturation, beginning of bunch touch to beginning of maturation,"Niagara Rosada" presented the longest duration in the four pruning times", according to the evaluated phenological stages.
Abstract: O experimento foi instalado no municipio de Aparecida do Rio Doce-GO, no sudoeste Goiano, durante os anos de 2007 e 2008, com o objetivo de avaliar o comportamento fenologico, bem como o requerimento termico em diferentes epocas de poda: (1) 09-07-07, (2) 28-09-07, (3) 03-03-08 e (4) 19-04-08. Avaliou-se a duracao, em dias, dos estadios fenologicos: poda ate gemas inchadas; gemas inchadas (gema algodao) a inicio de brotacao (ponta verde); brotacao a 5 - 6 folhas separadas; 5 - 6 folhas separadas ao inicio do florescimento; inicio do florescimento ao pleno florescimento, pleno florescimento a "chumbinho"; "chumbinho" a "ervilha"; "ervilha" a ½ baga; ½ baga a inicio da maturacao e inicio da maturacao ate plena maturacao. Os requerimentos termicos foram obtidos em termos de graus-dia (GD) necessarios para atingir os seguintes subperiodos: poda a brotacao, brotacao a floracao e floracao a colheita. A duracao do ciclo foi de 127; 130; 163 e 161 dias para as epocas de podas 1; 2; 3 e 4, respectivamente, sendo que, nas epocas 1 e 2, a colheita foi antecipada em 32 dias em relacao as demais. Os periodos compreendidos entre inicio e final de maturacao, ½ baga a inicio da maturacao; "ervilha" a ½ baga apresentaram a maior duracao nas 4 epocas de poda. O maior e o menor requerimento termico, considerando temperaturas-base de 10 e 12 °C, foram registrados para as podas de julho (menor ciclo) e de abril (segundo maior ciclo) com 2.214,5 e 1.911,5 GD e 1.960,3 e 1.638,3 GD, respectivamente.

TL;DR: Este trabalho foi empreendido para avaliar a distribuicao geografica da dengue em Jatai e sua relacao com a precipitacao, nos anos de 2004 e 2005, com base nos dados obtidos junto a Estacao Meteorologica de JataI, Laboratorio de Climatologia do Campus da UFG de JATAi e na analise of
Abstract: A influencia climatica sobre o homem pode ser tanto de maneira malefica quanto benefica. Quando de maneira malefica ela manifesta atraves de doencas, epidemias e endemias humanas. Desta forma, e de fundamental importância para a sociedade moderna entender a influencia e as correlacoes entre os elementos do clima e seus efeitos sobre a saude humana. Uma das formas de entender esta relacao e atraves das doencas tropicais, como a dengue, que ha muito se tornou um problema de saude publica em todo o mundo. O clima tem uma importância substancial na dispersao de alguns vetores que em condicoes socio-ambientais ideais, e otimizada, causando epidemias como a dengue. Esta doenca vem a muitos anos se adaptando ao meio urbano, aumentando o numero de casos nos centro urbanos. Nao diferente das outras cidades brasileiras, Jatai vem registrando diariamente varios casos de dengue. Porem o ano de 2005 a cidade de Jatai sofreu uma epidemia desta doenca, com o registro de 289 casos. Este trabalho foi empreendido para avaliar a distribuicao geografica da dengue em Jatai e sua relacao com a precipitacao, nos anos de 2004 e 2005, com base nos dados obtidos junto a Estacao Meteorologica de Jatai, Laboratorio de Climatologia do Campus da UFG de Jatai e na analise de casos confirmados de dengue obtidos. Palavras-chave: saneamento, geografia da medica, dengue, clima, saude publica.

TL;DR: In this paper, a trabalho foi analisar a temperatura de superficie and o uso da terra and cobertura vegetal na bacia hidrografica Barra dos Coqueiros.
Abstract: O sensoriamento remoto tem proporcionado o estudo climatico a partir do uso de imagens termais de satelites meteorologicos para o mapeamento da temperatura de superficie. A analise da temperatura de superficie em diferentes usos da terra e a cobertura vegetal pode fornece subsidio para a gestao e planejamento ambiental, como e o caso da bacia Barra dos Coqueiros (GO), que e uma regiao que possui grande exploracao dos recursos naturais, principalmente no que se refere ao uso do solo. O objetivo do trabalho foi analisar a temperatura de superficie e o uso da terra e cobertura vegetal na bacia hidrografica Barra dos Coqueiros. Utilizou-se para o mapeamento da temperatura superficial terrestre o programa Spring e Arcgis com as bandas 3, 4, 5 e 6 do Landsat 5, dia 20 de agosto de 2010. A equacao de Malaret (1985) citada por Tarifa; Armani (2000) foi utilizada na conversao dos pixels em valores em temperatura. A temperatura superficial terrestre foi comparada com temperaturas do ar distribuidas em pontos dentro da bacia. Verificou-se que na bacia a temperatura superficial terrestre variou entre 12,0 e 41,4°C, onde area recoberta por pastagens as temperaturas variaram entre 18,8 a 31,1°C e as areas de solo exposto apresentaram os maiores valores (36,4 a 41,4°C).

TL;DR: In this article, a microclimatic analysis of the microclima in pontos no interior das florestas estacionais semideciduais (FES) and em pontos fora das FES, em areas de pastagens, in Cacu and Cachoeira Alta-Alta-GO is presented.
Abstract: O presente artigo analisou o microclima em pontos no interior das florestas estacionais semideciduais (FES) e em pontos fora das FES, em areas de pastagens, na bacia da Usina Hidreletrica de Cacu (UHE-Cacu), situada nos municipios de Cacu e Cachoeira Alta-GO. Os dados de temperatura e umidade relativa do ar foram obtidos dos termohigrometros, na escala diaria, no periodo de setembro de 2011 a setembro 2012. A metodologia utilizada foi a escala microclimatica baseada em Geiger (1961) e Serafini Junior et al (2011) considerando um ponto no interior da FES com melhor estado de conservacao em relacao aos aspectos: a) variabilidade estrutural, ou seja, o tamanho das especies e os estagios de idade (mudas ate os senescentes) e b) preservacao pela nao infestacao de lianas, sinais de cortes de especies e pisoteio do gado, a altura dos individuos e maior diâmetro a altura do peito (DAP). Os pontos no interior das FES em melhor estado de preservacao apresentaram as menores temperaturas maximas absolutas 36,7 oC no P1 e 37,6 oC no P2, ja os pontos fora das FES, nas areas de pastagens apresentaram as maiores temperaturas maximas absolutas 42,8 oC no P7 e 42,6 oC no P5, esta diferenca no microclima ocorreu principalmente devido a estrutura da vegetacao nas FES e ao uso e ocupacao do solo.

TL;DR: Apesar dos avancos tecnologicos a sociedade ainda nao conseguiu tornarse independente dos recursos naturais.
Abstract: Apesar dos avancos tecnologicos a sociedade ainda nao conseguiu tornar-se independente dos recursos naturais. Desde a fase primitiva, quando o homem tinha uma relacao de dependencia total, a natureza era vista como fonte de alimento. Depois, o homem adquire o habito sedentario, criando novas habilidades tecnologicas, no intuito de dominar progressivamente a natureza. Entretanto, as sociedades evoluiram, sendo que o grande problema da civilizacao moderna, industrial e tecnologica e, talvez, nao ter percebido a dependencia com a natureza. Em busca do rompimento desta dependencia as sociedades, baseadas no seu modo de producao, apresentaram varios discursos ambientais. Nesse contexto sao apresentados os conceitos da relacao natureza/natural e homem/sociedade e alguns discursos como: da crise ambiental, dos ecologistas, do ecodesenvolvimento, da natureza como patrimonio de todos, do medo ecologico e da Universidade.

TL;DR: AT, DPT, R, RH and WS influenced the occurrence of a moderate MID, and variables with the highest odds ratio were AT-lag1 and RH-lag0 indicating an 8.9 and 18.1 times greater probability of amoderate MID, respectively.
Abstract: INTRODUCTION: Meteorological influences along with the lack of basic sanitation has contributed to disease outbreaks, resulting in large socio-economic losses, especially in terms of dengue. This study aimed to evaluate the meteorological influences on the monthly incidence of dengue in Arapiraca-AL, Brazil during 2008-2015. METHODS: We used generalized linear models constructed via logistic regression to assess the association between the monthly incidence of dengue (MID) of and 8 meteorological variables [rainfall (R), air temperature (AT), dew point temperature (DPT), relative humidity (RH), pressure surface, wind speed (WS), wind direction (WD), and gust], based on data obtained from DATASUS and meteorological station databases, respectively. The dengue-1 model included R, AT, DPT, and RH and the dengue-2 model included AT, DPT, RH, WS, and WD. A MID >100 (classified as moderate incidence) indicated an abnormal month. RESULTS: Based on the dengue-1 model, variables with the highest odds ratio included R-lag1, DPT-lag1, and AT-lag1 with a 10.1, 18.3, and 26.7 times greater probability of a moderate MID, respectively. Based on the dengue-2 model, variables with the highest odds ratio were AT-lag1 and RH-lag0 indicating an 8.9 and 18.1 times greater probability of a moderate MID, respectively. CONCLUSIONS: AT, DPT, R, RH and WS influenced the occurrence of a moderate MID.

TL;DR: The combination between winter pruned in August and green pruning in November was the most effective to obtain a second harvest in the same grapevine vegetative cycle, offering economic benefits to the producer and expanding the availability of fruit to consumers.
Abstract: This study aimed at tracking phenology, thermal demand and productivity of Niagara Branca, Niagara Rosada and Concord grapevines subjected to a dry pruning in winter and a green pruning in the end of spring, focused on obtaining two grapes harvests by vegetative cycle. The experiment was performed at Eldorado do Sul's Agronomic Experimental Station, Rio Grande do Sul State, Brazil, during the 2007/2008 harvesting. The plants were subjected to two dates of pruning in winter (07/22/07 and 08/20/07), performed by means of a short pruning, and two green pruning dates (11/15/07 and 12/17/07), performed by pruning the shoot starting from the fourth bud above the last grape cluster. The grapevine phenological sub periods considered were the vegetative, ranging from the pruning to sprouting and from the sprouting to flowering; and the reproductive, ranging from flowering to harvesting. Such ranges were monitored based on the degree-day accumulation. The grapevine production, total soluble solids and total titratable acidity were evaluated for the two crops. Results showed that all cultivars need around 1500 degree-days to complete their cycle, for both harvests. Early winter pruning increased the duration of the phenological cycle of plants compared to pruning performed in August due to the increased phenological subperiod pruning/flowering on the grapevines with early pruning. The anticipation of the winter pruning allowed advancing the first harvest, producing early grapes with higher market value. The phenological cycle of the second harvest was shorter than the first harvest due to higher temperatures during development of plants on the green pruning. The combination between winter pruning in August and green pruning in November was the most effective to obtain a second harvest in the same grapevine vegetative cycle. Plants subjected to green pruning provided a second harvest, between March/April, offering economic benefits to the producer and expanding the availability of fruit to consumers.

TL;DR: The aim of this study was to understand the consequences of temporal variability of air temperature in the occurrence of dengue in an area comprising seven municipalities of the Greater São Paulo and to verify that temperature peaks coincide with d Dengue outbreak peaks.
Abstract: Summary Introduction: Global climate changes directly affect the natural environment and contribute to an increase in the transmission of diseases by vectors. Among these diseases, dengue is at the top of the list. The aim of our study was to understand the consequences of temporal variability of air temperature in the occurrence of dengue in an area comprising seven municipalities of the Greater Sao Paulo. Method: Characterization of a temporal trend of the disease in the region between 2010 and 2013 was performed through analysis of the notified number of dengue cases over this period. Our analysis was complemented with meteorological (temperature) and pollutant concentration data (PM10). Results: We observed that the months of January, February, March, April and May (from 2010 to 2013) were the ones with the highest number of notified cases. We also found that there is a statistical association of moisture and PM10 with the reported cases of dengue. Conclusion: Although the temperature does not statistically display an association with recorded cases of dengue, we were able to verify that temperature peaks coincide with dengue outbreak peaks. Future studies on environmental pollution and its influence on the development of Aedes aegypti mosquito during all stages of its life cycle, and the definition of strategies for better monitoring, including campaigns and surveillance, would be compelling.

TL;DR: In this paper, the authors evaluated the influence of rootstocks on the duration of phenological stages and the accumulation of degree-days on a grape 'Niagara Rosada' in three seasons of pruning.
Abstract: It was evaluated the influence of rootstocks 'IAC 766', 'IAC 572', 'IAC 313', 'IAC 571-6' and 'Riparia do Traviu' and the pruning periods in the duration of phenological stages and in the accumulation of degree-days on grape 'Niagara Rosada' .The experiment was conducted in Louveira, SP. The treatments consisted of five rootstocks and three times of pruning, the experimental design being used in a completely randomized split plot with five replications, and plots represented by rootstocks and the subplots were pruning. After pruning the grapevine, were realized evaluations for phenological stages, using the criterion of Eichhon e Lorenz (1984). ). In three seasons of pruning, based on phenological stages, it was calculated the length of the periods: pruning to budding, pruning to the beginning of the flowering, pruning to the beginning of fruiting, pruning to beginning of ripening of the bunches, pruning the beginning of the harvest. Taking as a basis the cycle length of the vine and the average daytime temperatures, it was calculated the accumulation of degree-days. Data were submitted to ANOVA and Tukey test at 5% significance level. It was obtained in the summer pruning the reduction in duration of the phenological stages of 'Niagara Rosada' grafted on the rootstock 'Riparia Traviu'. The longer duration of the cycle and accumulation of degree-day of 'Niagara Rosada' cultivar were obtained with the rootstocks 'IAC 572' and 'IAC 313' pruning in the winter.
