title: FOOD PREFERENCE OF Thyrinteina arnobia (Stoll, 1782) (LEPIDOPTERA: GEOMETRIDAE) ON NATIVE AND EXOTIC HOSTS

description: ABSTRACT One of the factors that may affect and limit the production in eucalypt plantations is the attack of defoliating insects. Among those, the brown eucalypt caterpillar, Thyrinteina arnobia (Stoll, 1782) (Lepidoptera: Geometridae), stands out for being the major defoliating pest of Eucalyptus spp. in Brazil. Thus, the present study aimed to investigate the food consumption of T. arnobia, in its native host, guava (Psidium guajava L.), and in the different E. urograndis clones (VE 41, I 144, TP 361 and VCC 865). To assess T. arnobia food consumption, choice and non-choice tests were carried out using the native and the exotic host, alone or in combination. In non-choice tests, it was observed a higher consumption for the VE 41 clone and the native host (guava). The food consumption evaluation in choice tests indicated no food preference of T. arnobia between guava and E. urograndis clones, with the exception for the TP 361 clone, which was significantly less consumed than guava. In choice tests between the different E. urograndis clones, the clone I 144 presented a tendency towards lower food preference, being consumed only after 48 hours. In addition, the leaf consumption was similar between the VE 41, I1 14 e VCC 865 clones. In choice tests using the E. urograndis clones in pairs, the VE 41 clone was more consumed while the I 144 clone was less consumed when compared to the TP 361 clone. The obtained results provide basic information for the indication of eucalypt clones, and the understanding of the interaction and ecological relationships, assisting in the development of Forest Integrated Pest Management (Forest IPM) programs for the control of T. arnobia.

title: PERMEABILIZATION, CELL WALL ULTRASTRUCTURE, AND GERMINATION OF BASIDIOSPORES OF THE ECTOMYCORRHIZAL FUNGUS Pisolithus microcarpus TREATED WITH DIFFERENT COMMERCIAL BRANDS OF BLEACH

description: ABSTRACT Basidiospores of the ectomycorrhizal fungus Pisolithus microcarpus have an impermeable cell wall, a characteristic that is possibly related to the low germination percentages of these propagules, which makes it difficult to obtain monokaryons and use these spores in inoculants. The objective of this study was to evaluate the effect of different concentrations of commercial bleach on the permeabilization of P. microcarpus basidiospores and to analyze the alterations caused in the cell wall ultrastructure and the viability and germination capacity of these propagules. Fungal basidiospores were collected in eucalyptus plantations and permeabilized using different bleach concentrations and exposure times. The basidiospores were then analyzed by scanning and transmission electron microscopy. The percentage of permeabilized basidiospores varied with the commercial brand, bleach concentration, and exposure time. Basidiospores of different basidiocarps differed in susceptibility to permeabilization treatment with bleach. Changes in the ultrastructure of permeabilized basidiospores were observed at bleach concentrations of 15 and 50 % for an exposure time of 40 s, with surface changes and loss of the spicules of the outermost layer of the wall. After permeabilization with 5 % bleach for 40 s, 80 % of the permeabilized spores were viable, resulting in the production of fungal colonies after 15 days of incubation of these propagules in the presence of Corymbia citriodora. However, the germination percentage obtained, 0.001 %, was similar to that of non-permeabilized basidiospores, indicating that other factors, besides cell wall permeability, are determinant for the germination process.

title: STRUCTURING AND CHARACTERIZATION OF THE Acacia meanrsii De Wild CHARCOAL PRODUCTION CHAIN IN THE VALLEYS OF CAÍ AND TAQUARI, RS

description: ABSTRACT Due to globalization, market evolution, and technological implementations, the production chains have been improving, becoming essential for the consolidation of several products in the market, including charcoal, used as a renewable energy source. Thus, the objective of this work was to characterize the structure of this chain, from the qualitative and quantitative perspective, in the municipalities of the Valleys of Caí and Taquari and the interaction between the actors involved. The methodology was based on the division of the chain into macrosegments, with socioeconomic units of production characterized by the application of questionnaires. As a result, it was verified the presence of the production macrosegment (nursery and reforestation sectors), industrialization (charcoal production and packaging sectors), and commercialization (packaging sector), formed by family units. The packaging segment has outsourced manpower and more technology than the others. It was evidenced that a single socioeconomic unit of production can be part of more than one macrosegment or segment and, allied to this, in general, it is possible to perceive the characterization of a long chain of production. It appears that only 3.8% of charcoal producers also pack and sell their products, the remainder (96.2%) sell their production to packers who standardize the product, making the sale to the final consumer directly or indirectly.

title: ARTIFICIAL NEURAL NETWORKS (ANN) FOR HEIGHT ESTIMATION IN A MIXED-SPECIES PLANTATION OF Eucalyptus globulus LABILL AND Acacia mearnsii DE WILD

description: ABSTRACT The objective of this study is to evaluate the fit of Artificial Neural Networks (ANN) for height estimation and evaluation of the effects of consortium in a mixed-species plantation of Eucalyptus globulus (E) and Acacia mearnsii (A). The experiment was installed in 2005, on two farms in the municipality of Piratini - RS, where was planted the species Eucalyptus globulus (E) and Acacia mearnsii (A), in monoculture and mixed in simple lines (50%E:50%A - SL), and double lines (50%E:50%A - DL). The training and evaluation of the networks were made in R-project with the package neuralnet. All ANNs, from the simplest to the most complex, showed high values for Rŷy and low for Syx, BIAS and RMSE, with superior results in ANN 3, 4, and 6, which demonstrates that the information of DBHmin, DBHmean, and DBHmax were important stand attributes. Furthermore, the ANNs were able to capture the different growth patterns shown by the species in the different forms of consortiums, therefore is indicated for the height estimation in monocultures and mixed plantations of Eucalyptus globulus and Acacia mearnsii, and only one ANN would be necessary to represent the entire population.

title: EFFECTS OF ARTIFICIAL SHADING AND IRRIGATION WITH BRACKISH WATER ON THE INITIAL DEVELOPMENT OF Anadenanthera colubrina (Vell.) Brenan PLANTS

description: ABSTRACT The use of management strategies or changes in the cultivation environment can reduce the impacts of irrigation water salinity on plant development. Therefore, in this research, physiological responses, initial growth, and plant quality of Anadenanthera colubrina (Vell.) Brenan (Angico Branco) were evaluated under different levels of shading and electrical conductivity of the irrigation water, seeking to identify the most favorable conditions for the development of this species using brackish water. The experiment was carried out in randomized blocks with split plots and four replications. The plots were formed by four environments with different shading levels: 0 (full sun), 30, 50, and 70%, and the subplots, formed by five increasing levels of electrical conductivity of the irrigation water: 0.4, 1.6, 2.8, 4.0, and 5.2 dS.m−1. The following variables were evaluated: substrate electrical conductivity, leaf gas exchange, plant height, biomass production, and Dickson quality index at 40 days in a nursery. The use of artificial shading favored plant development and photosynthesis rate, even when irrigated with moderate and high salinity water. The DQI showed that A. colubrina plants presented higher quality index when produced under intermediate shading (30% and 50%), with yield losses below 20% when irrigated with water with electrical conductivity up to 2.8 dS.m−1.

title: INFLUENCE OF THE TIMBER ELASTIC MODULUS ON THE GEOMETRIC NONLINEAR STRUCTURAL ANALYSIS OF TRUSS ARCHES

description: ABSTRACT In this work, it was numerically evaluated the influence of the modulus of elasticity parallel to the wood grain on the stability of trussed arches considering a nonlinear geometric analysis based on the Finite Element Method (FEM). This approach was carried out according to a positional formulation of the FEM, considering the structural nodes as main variables of the nonlinear equations system, whose resolution was obtained using the Newton-Raphson method. Altogether, seven arch models were evaluated, consisting of coniferous and hardwoods, with properties defined according to the strength classes of the Brazilian standard ABNT NBR 7190. The subroutines were written in MATLAB to solve the system of nonlinear equations and perform the analysis, including the graphical representation of the results and configurations of the trussed arch. Internal loads and displacements were obtained, in addition to the instability loads of the trussed arches. It was found that the instability load of the arch made with the stiffest hardwood (D60) was approximately equal to 700% of the instability load of the C20 coniferous class and equivalent to 257.8% of the D20 hardwood class-related load. It was verified that the modulus of elasticity significantly influences the nonlinear geometric behavior of the timber trussed arch. Furthermore, the nonlinear geometric analysis allowed calculating more accurate parameters and the verification of the stability of the structural system.

title: NATIVE CAATINGA SPECIES FOR THE RECOVERY OF DEGRADED AREAS IN THE BRAZILIAN SEMIARID REGION

description: ABSTRACT This study aimed to prospect, among the species that grow spontaneously in compacted landfills, native Caatinga plants with potential for ground cover in extremely impacted areas, with exposed soil. Initially, a general floristic survey was carried out in the four study areas. To prospect the species, data referring to the richness, coverage, and densification of plants in the herbaceous stratum were collected in each study area, using the method of plots. The selection was based on species-specific characteristics: origin, plant habit, life cycle, propagation, dispersion syndrome, coverage, densification, and allelopathic effect. The general floristic inventory revealed the presence of 73 species belonging to 63 genera and 26 botanical families. In the survey of the coverage and densification of the herbaceous stratum, 33 species belonging to 32 genera and 16 families were found, being the most representative: Fabaceae (5), Malvaceae (5), and Poaceae (5). As for the origin, 26 are native, one is naturalized, and six are exotic, of which 66.6% are in the Poaceae family. Moreover, most of these species are herbs, with an annual life cycle, dissemination through seeds, and present autochoric dispersion. The coverage and densification of these species ranged from 0.44% to 9.5% of the area and 1 to 4.44 of individuals/m2, respectively. The species Senna uniflora, Rhaphiodon echinus, Sida galheirensis, Mesosphaerum suaveolens, Hexasepalum teres, Waltheria rotundifolia, Trianthema portulacastrum, and Herissantia crispa showed potential for use in recovery plans for degraded areas based on the results presented by each of them in the parameters analyzed, especially in coverage, densification, dispersion syndrome, and life cycle.
