title: Spatiotemporal Dynamic Analysis of Heat Spots in Two Indigenous Lands of Mato Grosso State: a Geoespatial Approach Over the a Dynamic of Fire Use by Xavantes and Bororos

description: ABSTRACT The article aimed to use geotechnology to study the occurrence of heat spots detected sensors on board of NOAA-12 and NOAA-15 satellites, between the years 2000 and 2010 in a region located on east of Mato Grosso state. It was observed that in the Merure, belonging to Bororo people and São Marcos, belonging to Xavante people indigenous lands the heat spots were presented in different patterns that can be attributed to the distinct ways of fire management by each ethnic group. The practice of hunting with the use of fire influenced the higher concentration and considerable densities of hot spots distributed throughout inside the Xavante`s territory compared to the Bororo´s and in the surrounding buffer areas of São Marcos. In the Bororo territory was observed that the hot spots were presented in higher densities close to the highways that crosses its territory.

title: Arbuscular Mycorrhizal Fungi in Two Forest Fragments of Periodically Floodable Restinga at Marambaia, RJ

description: ABSTRACT The present study aimed to evaluate the arbuscular mycorrhizal fungi (AMF) ocurrence in two forest fragments (FF 1 and FF 2) of periodically floodable Restinga, arranged in a gradient of soil water saturation at Marambaia, RJ. Soil samples were collected at a depth of 0-5 cm to evaluate the AMF community and soil atributes. Six AMF species were found, five of them occurred in both areas and Acaulospora scrobiculata were restricted to FF 1. Acaulospora and Glomus were the best-adapted genus to the ecosystem conditions. There was no significant difference between the forest fragments in relation to the species richness. However, spores abundancy was higher in FF 1. Some of these results were influenced by lower values of availability of P, moisture content and temperature in soil at FF 1, in relation to FF 2.

title: Hipsometric Rate for Pinus taeda L. at Different Stages of the Cutting Cycle

description: ABSTRACT This study aimed to evaluate the different phases of the cutting cycle, seeking a proper hypsometric rate to estimate the height of these different phases in a reforestation of Pinus taeda. The study consisted of five treatments, being the fifth the combination of the data belonging to the other treatments. The sampling followed the fixed area method where plots size and number of dominant trees varied with each cutting cycle. The plots location was defined by simple random sampling (eight portions by cutting cycle). We determined the statistical adjustments, adjusted coefficient of determination, standard error and residual analysis. We performed the Graybill identity test to assess the need to use different models for different age classes. Results showed that there are significant differences between adopting a specific model to each stage and use a single best model for the full settlement.

title: Analysis of the Preservative Treatment Influence on Tropical Timbers Surfaces Color and Roughness

description: ABSTRACT Although the chemical treatments increase wood durability, there are side effects due to the use of some products, such as the change of its original color and in its surface. The present work aimed to evaluate the surface of three tropical wood species impregnated with CCA preservative using colorimetric and roughness techniques. We used three tropical wood species representing groups of low, medium and high density. The color of the wood samples changed significantly, darkening with reduction of red and yellow pigments and a tending to surface`s greening. Regarding roughness, all samples showed an increase in the arithmetic mean roughness (Ra) and the mean maximum height (Rz), increasing surface roughness.

title: Effect of Particleboard Type in Physical and Mechanical Properties

description: ABSTRACT This study aimed to evaluate physical and mechanical properties of conventional agglomerate, medium density particleboard and agglomerate with laminate inclusion. Particleboards were made of Acacia mangium particles and laminas of Schizolobium amazonicum were used to produce agglomerate with laminate inclusion. Conventional agglomerate and agglomerate with laminate inclusion showed hygroscopic equilibrium moisture statistically superior to MDP. Agglomerate with laminate inclusion showed the highest rate of thickness swelling after 2 hours of immersion in water, the highest modulus of rupture in bending strength and the best screw withdraw resistance. MDP presented the highest mean value of board internal bond strength. There were no significant differences in other evaluated properties. It was concluded that laminate inclusion improved modulus of rupture and screw withdraw resistance while the use of fine particles on the faces improved physical properties of the particleboards.

title: Physical and Mechanical Characterization of Eucalyptus camaldulensis Young Wood for Rural Architecture Uses

description: ABSTRACT This study aimed to analyze the quality of Eucalyptus camaldulensis young wood of planted trees in Rio Tinto, Paraíba, Brazil, for use in rural architecture. Physico-mechanical tests were carried out through simplified characterization. The physical tests obtained were moisture content, basic and apparent specific gravity and shrinkage of the wood, in addition to the anisotropy coefficient. To obtain the compression parallel to fibers results, linear variable differential transformers (LVDTs) bound to the sample and the data acquisition system for the determination of the resistance and stiffness values of wood were used. The values obtained showed that the young wood of E. camaldulensis fits in 20 C strength rating for hardwoods, determined by the Brazilian Standard, still not being recommended for structural purposes, but appropriate to be applied in secondary elements of rural architecture, as fences, playgrounds and for rustic furniture manufacture.

title: Tests of Drying Rate and Scoring of Defects for the Prediction of Conventional Kiln Drying Quality of Eucalyptus sp. Wood – Part 2

description: ABSTRACT This research is a continuation of Klitzke & Batista (2010) work. The main objective was to assess whether the wood quality in the methodology of drastic drying test at 100 °C corresponds to that of conventional kiln drying. It was used 11 years old Eucalyptus saligna, Eucalyptus grandis and Eucalyptus dunnii woods, which were kiln dried together in the same batch in a pilot scale kiln, doing three repetitions. Drying defects evaluated were end and surface cracks, cupping and collapse, which generated a mean score by species, which was compared to the score of defects of the drastic drying test, as well as to the basic density and the total volumetric shrinkage. Eucalyptus grandis and Eucalyptus saligna had higher wood quality in conventional drying than Eucalyptus dunnii. It was rejected the hypothesis of using the score of defects in drastic drying test as a way of predicting the quality of conventional kiln drying.

title: Soil Fauna Communities and Soil Attributes in the Agroforests of Paraty

description: ABSTRACT We conducted the present study in Paraty, southeastern Brazil, in areas under different management regimes and plant cover. The study comprised two different agroforestry systems (AFS-1 and AFS-2), a secondary forest, and a cassava monoculture. We aimed at assessing the effects of land use on the soil fauna and its relationship with soil chemical (pH, Al, Ca, Mg, P, K, carbon, and organic matter) and microbiological attributes (soil microbial biomass carbon - SMB-C, soil respiration – SR, metabolic quotient - qCO2, microbial biomass carbon - C-mic). During winter, AFS-2 showed higher abundance of microphagous, saprophagous, and total individuals than the other areas. AFS-1 and the forest showed an increased abundance of Formicidae and phytophagous groups from winter to summer. The soil fauna and community structure showed that the studied agroforests are under regeneration, becoming more similar to the native forest, where ecological processes are considered efficient.

title: Insecticides Assessment on Thaumastocoris peregrinus (Hemiptera: Thaumastocoridae) Bronze Bug Control in Laboratory Conditions

description: ABSTRACT The study aimed to evaluate the control efficiency of insecticides on Thaumastocoris peregrinus in the laboratory conditions. Therefore, 15 plants of Eucalyptus dunnii received the follow field spray: imidacloprid (78.8g ai / ha), thiamethoxam (37.5g ai / ha), lambda-cyhalothrin + thiamethoxam (21.2 + 25.8g ai / ha), lambda-cyhalothrin (24.9g ai / ha), and the untreated control only water. To determine the insecticides efficiency, we used a containment test, with E. dunnii leaves sprayed and collected at two different times. In the laboratory was used eight reps of leaves to adult and eight to nymphs by treatment individually placed in petri dishes; each repetition received 10 insect specimens. Assessments of alive insects were carried out at second, fourth, twentieth, twenty-fourth days after spray treatment (DAT). We conclude that the insecticides tested, on respective rate, presented efficient control of T. peregrinus nymphs and adults.
