TL;DR: O objetivo do trabalho foi analisar a precipitacao pluvial ea temperatura do ar em relacao ao numero of casos de dengue em 2011, na cidade de Jatai - GO.
Abstract: As areas urbanas sao capazes de provocar impactos sobre o clima local, contribuindo de formanegativa ou positiva para a qualidade ambiental da populacao. Assim os elementos climaticos podemafetar a sobrevivencia e reproducao de agentes patogenicos, principalmente de mosquitostransmissores da malaria e da dengue. As transformacoes recentes podem estar causando alteracoes nohabitat do mosquito no municipio de Jatai. O objetivo do trabalho foi analisar a precipitacao pluvial ea temperatura do ar em relacao ao numero de casos de dengue em 2011, na cidade de Jatai - GO. Apesquisa utilizou os Termohigrometro- HT4000 para coletar a temperatura do ar e pluviometros paracoletar as chuvas. Ha impactos na saude causados pelos fenomenos climaticos, sendo eles diretos ouindiretos, como exemplo, nas localidades que tiveram os maiores casos de dengue, a Vila Olavo e VilaFatima, tambem ocorreram os maiores valores pluviometricos 363,4 mm. O Centro, no mes de abrilapresentou o maior numero de casos (9 casos), pois teve a maior temperatura media do mes (25,9°C),sendo que temperatura entre 20,0oC a 46,0oC, sao ideais para procriacao da dengue (COSTA, 2001).

TL;DR: In this article, a pesquisa foi avaliar a temperatura do ar, maximas e minimas absolutas, na area urbana de uma cidade de pequeno porte do Cerrado Brasileiro, Jatai-GO.
Abstract: O objetivo da pesquisa foi avaliar a temperatura do ar, maximas e minimas absolutas, na area urbana de uma cidade de pequeno porte do Cerrado Brasileiro, Jatai-GO. A pesquisa teve como base metodologica a teoria do clima urbano de Monteiro (1976) e Monteiro e Sezarino (1990), abordando o subsistema termodinâmico considerando a temperatura do ar e correlacionando com a hipsometria, declividade, exposicao das vertentes e o uso do solo. Para a coleta dos dados, foram instalados na area urbana da cidade 9 termohigrometros, no periodo de agosto de 2013 a julho de 2014. Para a confeccao dos mapas como: hipsometria, exposicao das vertentes, uso da terra foram utilizados SIG Arcgis 10.1. Constatou-se que o valor maximo absoluto de temperatura foi de 43,1°C no P1, as 13h25m, em que o uso do solo influenciou os valores entre os pontos de coleta. Os menores valores de temperaturas minimas tambem ocorreram em agosto, nos dias 28 e 29, sobe a atuacao de uma frente estacionaria, em que Jatai teve 4,9°C no P6, com muito baixa taxa de construcao (1,1%) e alta taxa de vegetacao (81,5%), alem de ser localizado em fundo de vale

TL;DR: O mosquito transmissor da dengue vem, ao longo do tempo, se adaptando ao meio urbano, pois, e neste ambiente that encontra as condicoes ambientais e sociais ideais para a sua procriacao ocorreu grande variabilidade na distribuicao da d Dengue nos bairros.
Abstract: Os atuais estudos de geografia da saude vem abordando, principalmente, a influencia do meio geografico, as alteracoes ambientais e a organizacao social, sobre a saude e qualidade de vida das pessoas. Esses estudos, em sua maioria, visam contribuir com os programas de saude publica e de planejamento ambiental urbano. Nesse sentido, este presente artigo tem como objetivo analisar a variabilidade da precipitacao pluvial com o numero de casos de dengue no municipio de Jatai-GO, no periodo de 2007 a 2009. Foram instaladas estacoes automaticas para mensuracao dos elementos climaticos como temperatura do ar e umidade do ar e pluviometros para a coleta da precipitacao pluvial, em varios pontos no perimetro urbano. Esses dados foram tabulados e correlacionados com os casos confirmados de dengue. Desta forma, no periodo de 2007 a 2009, ocorreu grande variabilidade na distribuicao da dengue nos bairros. Os maiores numeros de casos se concentraram na regiao do Centro Tecnico Sucam, com 181 de ocorrencias, de um total de 703 casos registrados, correspondendo a 26%. O bairro Centro e Vila Fatima foram os que apresentaram o maior numero de casos, registrando 49 e 89 casos de dengue respectivamente. Em seguida o setor Aeroporto com o registro de 39 casos de dengue. Embora o mes de marco fosse o mais chuvoso (acima de 320 mm), os maiores numeros casos de dengue ocorreram apos o mes de marco, nos meses de abril (109 casos) e maio (107), pois e neste periodo em que ha uma diminuicao das chuvas e do escoamento superficial, alem acumulo de agua nos recipientes que favorecem a proliferacao de larvas, confirmado por Silva (2006 e 2007). A partir dos resultados obtidos, consideramos que o mosquito transmissor da dengue vem, ao longo do tempo, se adaptando ao meio urbano, pois, e neste ambiente que encontra as condicoes ambientais e sociais ideais para a sua procriacao. Os maiores indices de casos de dengue em Jatai seguem um padrao sazonal na estacao do verao e outono, principalmente nos meses de marco, abril e maio com condicoes ambientais propiciam ao desenvolvimento dos ovos do mosquito Aedes aegypti.

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 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: This work shows how the mammalian fauna of medium and large size are structured in a semideciduous seasonal forest fragment of 36.5 ha in the urban area of Jatai, Goias and suggests the prevention of entrance of people and of domestic animals and increased connectivity of the fragment with the landscape external to theurban area in order to allow the movement of the currently present species.
Abstract: Nowadays, the processes of deforestation and loss of habitats represent a major threat to many species of mammals. These processes cause changes in natural landscapes by decreasing area, connectivity, and fragment size, and increasing edge effects and number of fragments. Understanding which and how many species persist in disturbed fragments may indicate the species' minimum requirements and might contribute to their conservation. Here we show how the mammalian fauna of medium and large size (higher than 1 kg) are structured in a semideciduous seasonal forest fragment of 36.5 ha in the urban area of Jatai, Goias. We performed the sampling with 30 sand track plots (1 x 1 m). We analyzed the relative record frequency and built a collector's curve to demonstrate the sampling effort. With a total effort of 600 track plots × days, we recorded twelve species of mammals with our tracks sampling method, from which only the wild mammals were included in the analyzes (11 species). The estimated species richness reached 13 species (SD (Standard Deviation) = ±1, CI (Confidence Interval) = ±2 (11 – 15 species). The species with the highest relative record frequency was Didelphis albiventris and the species with the lowest was Tamandua tetradactyla. The fragment size must be a limiting factor to the richness and to the occurrence of species, as it may not be sufficient to allow the persistence of a population or an individual. Disturbances that originated from houses, like domestic animals and movement of people, also contributed to the removal and extinction of species. To conserve the species in the fragment, we suggest the prevention of entrance of people and of domestic animals. We also recommend increased connectivity of the fragment with the landscape external to the urban area in order to allow the movement of the currently present species.

TL;DR: In this article, the authors used data from the Food and Agriculture Organization of the United Nations (FAO) (1986 to 2017) and the World Bank (2018) to determine the positioning and evolution of Brazil in the international fresh fruit market.
Abstract: The fruit growing activity is of great importance for Brazilian agribusiness as the country is the third largest fruit producer in the world. Despite this notability, the fruit market presents obstacles especially related to international trade. Thus, the present study sought to determine the positioning and evolution of Brazil in the international fresh fruit market. Data used in the research were obtained from the Food and Agriculture Organization of the United Nations (FAO) (1986 to 2017) and the World Bank (2018), using metrics of export flow, quantity and income of countries related to the main fruits exported by Brazil in the first quarter of 2020. Data were manipulated, transformed into figures and graphs for better visualization of information. The Brazilian position in the in the ranking of fresh fruit exports was not very dynamic during the evaluation period, being dependent on the demand from high-income European countries.

M. deRAINFALL CHARACTERISTICS AND VEGETATION INTERCEPTION IN THE CAATINGA BIOME 2 ABSTRACT The mechanism of vegetation interception depends largely on the rainfall characteristics and canopy of the trees. The main objective of this study was to analyze the effects of the rainfall characteristics (precipitation classes (RC) - RC < 15 mm, 15 mm ≤ RC < 30 mm, 30 mm ≤ RC < 60 mm and RC ≥ 60 mm and intensity classes (IC) - 1,1 mm h-1 ≤ IC < 5 mm h-1, 5,1 mm h-1 ≤ IC < 25 mm h-1, 25,1 mm h-1 ≤ IC < 50 mm h-1 and IC ≥ 50,1 mm h-1) and the seasonal variations of the interception in an area with regenerating caatinga. The experiment was conducted on an experimental catchment in the municipality of Iguatu, Ceara, during six consecutive years, from 2010 to 2015, with a total of 212 events. Internal precipitation, tree trunk runoff and loss by interception in areas of 10 x 10 m were monitored. The total rainfall was measured with a “Ville de Paris” rain gage, installed in an open area. No seasonal changes were observed (wet season – January through June – and dry season – July through December) among the average percentages of internal precipitation (Pint), tree trunk runoff (Esc) and loss by interception (I), due to the rainfall and vegetation characteristics. The results show that the smallest relative losses by interception were observed in the precipitation classes over 60 mm and, among the most intense events, the average loss percentages by interception are smaller. Keywords: Rainfall classes, rainfall intensities, seasonal variability.
