| 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,... |

| 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... |

| 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... |

| ABSTRACT: The present research hypothesized that the thermal, lighting and acoustic environments in commercial swine farrowing rooms vary over time and from crate to crate. This study was conducted on 27 replicates in two commercial farrowing rooms in North Central Indiana, each equipped with 60 farrowing crates. Temperature, relative humidity, light intensity, sound intensity, and air velocity were continuously monitored and estimated for each crate at the sow level, for 48 h post-farrowing, which is usually a critical period for piglet survivability. Average daily temperature for all the crates in Room 1 was 24.1 ± 2.0 °C, 1.0 °C lower (p < 0.05) than in Room 2. Although the overall mean temperature was similar between rooms and seasons, frequency... |

| Despite the importance of leaf wetness duration for plant disease epidemiology, there has been little attention paid to research on how its variability relates to different cropping situations. The objective of this study was to evaluate the spatial variability of leaf wetness duration (LWD) in three crops, comparing these measurements with turfgrass LWD, obtained in a standard weather station. LWD was measured by electronic sensors in three crops with different canopy structures and leaf area: cotton, coffee and banana. For the cotton crop, cylindrical sensors were deployed at the lower third and on the top of the canopy, facing southwest. For the coffee crop, flat plate sensors were installed in the lower third of the canopy facing northeast and... |

| The aim of this study was the study of the abiotic environment of the carnivorous pitcher plant Heliamphora nutans (Sarraceniaceae), including the microclimate and the geochemistry of the soil of the growing sites on Roraima Tepui and discuss their relevance within the recent model of carnivorous plant ecology. The soil was peaty and low in nutrients. The microclimate on the site was very balanced, with moderately cool temperatures, a constant high humidity and very low wind speed. Heliamphora was not exposed to any recognizable climatic stress. Previous macroclimatic measurements reflected the growth conditions of Heliamphora only incorrectly, since humidity decreased drastically with height. The apparent conflict with the common model of carnivorous... |
