| A análise climática do assentamento rural do Taquaral constitui uma significativa fonte de referência de informações para técnicos e interessados em formular políticas públicas para os agricultores familiares que tiram o seu sustento na região. A maioria deles relata que as condições climáticas estão entre as principais dificuldades que enfrentam na sua rotina na lavoura. Além disso, tais informações são a base para o estabelecimento de um calendário apícola na região. A produção de produtos apícolas nos assentamentos de Corumbá é uma das atividades realizadas a algum tempo e existe um interesse crescente dos assentados em produzir através da apicultura. Dessa forma, acreditamos que a publicação é uma contribuição técnica de grande valia para a... |

| ABSTRACT This study aimed to investigate the applicability of artificial neural networks (ANNs) in the prediction of evapotranspiration of sweet pepper cultivated in a greenhouse. The used data encompass the second crop cycle, from September 2013 to February 2014, constituting 135 days of daily meteorological data, referring to the following variables: temperature and relative air humidity, wind speed and solar radiation (input variables), as well as evapotranspiration (output variable), determined using data obtained by load-cell weighing lysimeter. The recorded data were divided into three sets for training, testing and validation. The ANN learning model recognized the evapotranspiration patterns with acceptable accuracy, with mean square error of 0.005,... |

| O presente trabalho visou caracterizar o microclima da área com vegetação remanescente de mata ripária diferenciando da área com vegetação de pastagem degradada. Foram medidos em estações meteorológicas automáticas, durante o ano de 2014, os principais elementos meteorológicos com registros dos totais e médias diárias da radiação solar (MJ/m-2), temperatura do ar (oC), umidade relativa do ar (%), e precipitação total (mm). A radiação incidente anual na área degradada foi de 220,2 MJ.m-2, enquanto que na mata 23,5 MJ.m-2.A temperatura atmosférica média anual, na área com remanescente de mata, foi atenuada em 0,9 oC e a média das máximas diárias em 2,8 oC, porém a temperatura média das mínimas diárias teve um aumento de 0,8 oC, a umidade relativa da... |

| Laboratory studies with 1st instar of southern green stink bug, Nezara viridula (L.) indicated that relative humidity (RH) greatly affected nymph emergence and survivorship up to the 2nd instar, reaching the maximum value (<FONT FACE=Symbol>»</FONT> 90%) with RH of > 80%. At 60% RH, 60% of the nymphs emerged and survived, while with 0% RH only <FONT FACE=Symbol>»</FONT> 15% of eggs hatched, and most nymphs died. Emerged nymphs from egg masses placed in plastic boxes with a gradient of humidity remained on egg shells for ca. one day. After this period, they dispersed and regrouped on top of shells 6.8 ± 0.67 times, until they abandoned the shells toward the source of humidity, avoiding the water-saturated areas. Duration taken for... |

| A study was conducted on description of the sheep houses ( materials, location, orientation ,……etc) and its effect on microenvironment in two housing ( concrete roofing material, Iron sheet roofing material ) in Giza , Egypt. In order to select the appropriate type of housing that provides the best inside climate throughout making adjustment in housing. During the experimental period, maximum temperature was recorded under Iron sheet and lowest temperature as in Concrete. The maximum protection from high temperature was given in concrete than in Iron sheet. Adjustment of temperature and relative humidity through the... |

| Agroforestry systems were established as a viable option for Brazilian farmers in recent decades. Shading is expected to affect the system?s microclimate and thus it is likely to alter water fluxes to the atmosphere via evapotranspiration. In this study we measured the evapotranspiration (ET) with micro-lysimeters in four different treatments as a proxy for different land use systems at EMBRAPA Beef Cattle, the Brazilian Agricultural Research Corporation, located in Campo Grande-MS, Brasil. The four treatments are: Integrated systems with rows of Eucalypt (Eucalyptus urograndis) trees (ICLF), integrated systems without Eucalypt trees (ICL), continuous pasture (CP) and native Cerrado (Savannah) vegetation. In the ICLF and ICL plots Bracchiaria brizantha was... |

| Measurements of solar global radiation, wind speed, temperature and relative humidity of air were made in a coffee plantation (Coffea Arabica L. variety Icatu Vermelho- IAC 4045), grown under conditions of shading levels caused by grevillea trees (Grevillea robusta) in Mococa-SP region (21° 28’ S, 47° 01’ W, altitude 665m), between January and December 2005, aiming to show the effects of shading crop system on the microclimate. The results showed that there was a reduction of about 26% of solar global radiation in the shaded systems, with a monthly variation of 24-30%. It has been highlighted some differences in the transmittance of global radiation in the shaded coffee trees due to the spatial variation of grevillea canopy. There was a... |
