Effect of relative humidity on emergence and on dispersal and regrouping of first instar Nezara viridula (L.) (Hemiptera: Pentatomidae)
Provedor de dados: Neotropical Entomology
Autores: Hirose,Edson; Panizzi,Antônio R.; Cattelan,Alexandre J.
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 (&lt;FONT FACE=Symbol&gt;»&lt;/FONT&gt; 90%) with RH of &gt; 80%. At 60% RH, 60% of the nymphs emerged and survived, while with 0% RH only &lt;FONT FACE=Symbol&gt;»&lt;/FONT&gt; 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...

Provedor de dados: Revista Brasileira de Fruticultura
Autores: Chavarria,Geraldo; Santos,Henrique Pessoa dos; Castro,Luis Antônio Suita de; Marodin,Gilmar Arduíno Bettio; Bergamaschi,Homero.
The present study evaluated the anatomy, chlorophyll content and photosynthetic potential of grapevine leaves grown under plastic cover. The experiment was carried out in vineyards of Moscato Giallo cultivar covered and uncovered with plastic. A block design with 10 selected plants was used for each area (covered and uncovered). Twelve leaves (six of them fully exposed to solar radiation and six grown under shaded conditions) were collected from each area and were fixed and analyzed microscopically (thickness of the adaxial and abaxial epidermis and of the palisade and spongy parenchymas). Chlorophyll content and photosynthetic potential were determined in the vineyard at veraison and after harvest. Plastic covering increased the thickness of the palisade...

Microenvironments in swine farrowing rooms: the thermal, lighting, and acoustic environments of sows and piglets
Provedor de dados: Scientia Agricola
Autores: Morello,Gabriela Munhoz; Lay Jr.,Donald C.; Rodrigues,Luiz Henrique Antunes; Richert,Brian T.; Marchant-Forde,Jeremy Neville.
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 &lt; 0.05) than in Room 2. Although the overall mean temperature was similar between rooms and seasons, frequency...

Validation of the Deardorff model for estimating energy balance components for a sugarcane crop
Provedor de dados: Scientia Agricola
Autores: Rolim,Glauco de Souza; Escobedo,João Francisco; Oliveira,Amauri Pereira.
The quantification of the available energy in the environment is important because it determines photosynthesis, evapotranspiration and, therefore, the final yield of crops. Instruments for measuring the energy balance are costly and indirect estimation alternatives are desirable. This study assessed the Deardorff's model performance during a cycle of a sugarcane crop in Piracicaba, State of São Paulo, Brazil, in comparison to the aerodynamic method. This mechanistic model simulates the energy fluxes (sensible, latent heat and net radiation) at three levels (atmosphere, canopy and soil) using only air temperature, relative humidity and wind speed measured at a reference level above the canopy, crop leaf area index, and some pre-calibrated parameters...

Spatial variability of leaf wetness duration in cotton, coffee and banana crop canopies
Provedor de dados: Scientia Agricola
Autores: Santos,Eduardo Alvarez; Sentelhas,Paulo Cesar; Pezzopane,José Eduardo Macedo; Angelocci,Luiz Roberto; Monteiro,José Eduardo Boffino Almeida.
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 effects of fragmentation on Araucaria forest: analysis of the fern and lycophyte communities at sites subject to different edge conditions
Provedor de dados: Acta Botanica Brasilica
Autores: Silva,Vinícius Leão da; Schmitt,Jairo Lizandro.
Edge effects impact species richness and composition as a result of environmental changes caused by fragmentation. This study analyzed edge effects on a community of terrestrial ferns and lycophytes in an Araucaria forest in Brazil at sites subjected to differing edge conditions: (1) a site bordering a road running through the interior of a conservation unit, and (2) a site bordering an agricultural property. Twelve 10 × 10 m plots were selected at the edge and in the interior of each site, and accounted for a total of 48 plots. The edges had lost their characteristic floristic identity, suggesting that many species are sensitive to variations in environmental conditions. The edge effect had a negative impact on species richness as shown by the greater...

Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: BOSI,CRISTIAM; PEZZOPANE,JOSÉ RICARDO M.; SENTELHAS,PAULO CESAR.
Abstract  The aim of the present study was to assess the effect of Eucalyptus trees in a silvopastoral system on the microclimate and the capacity of that to mitigate the effects of climate change on pasturelands. This study included an open pasture of Piatã palisadegrass and an adjacent pasture that contained both palisadegrass and East-to-West rows of Eucalyptus trees, with 15 m between rows, 2 m between trees within rows. The micrometeorological measurements were collected at several distances from the tree rows and in the open pasture. The silvopastoral system was associated with greater between-row shading when solar declination was high and greater near-tree shading when solar declination was around -22°. Both soil heat flux and temperature were...

Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Adlassnig,Wolfram; Pranji,Kornelija; Mayer,Edith; Steinhauser,Georg; Hejjas,Flora; Lichtscheidl,Irene K.
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...
