title: TREE COMPONENT DEMOGRAPHY IN AN UPPER MONTANE MIXED OMBROPHILOUS FOREST UNDER CHRONIC ANTHROPOGENIC DISTURBANCES

description: ABSTRACT The objective of this study was to understand the dynamics of an Upper Montane Mixed Ombrophilous Forest in the municipality of Painel, Santa Catarina, Brazil, where low-level but chronic disturbances, such as extensive cattle grazing and exploitation of non-timber products, are common practices. In 2008, permanent plots were allocated and all tree species with circumference at breast height (CBH) equal to or greater than 15.7 cm were measured. A second survey was conducted in 2014 by the same methodology. Mortality, recruitment, and basal area gain and loss rates were then determined. The tree species were classified into regeneration guilds and proportion tests were conducted to verify the associations between dynamics patterns and guilds. The community has shown a 2.3%.year-1 average mortality rate, a 2.2%.year-1 average recruitment rate, a 3.0%.year-1 average basal area gain rate and a 1.8%.year-1 average basal area loss rate. Species number has decreased from 55 to 48. Regeneration guilds have shown different dynamics patterns, where the pioneers have shown the greatest mortality (19.9%) and recruitment (15.6%) proportion and reduced representativeness in shade-tolerant climax species. Therefore, floristic impoverishment and higher representativeness reduction of late species have been observed. We have concluded that despite disturbances do not result in structural deterioration, they have the potential to slow the succession process and cause a floristic homogenization in the area under study.

title: EQUATIONS TO ESTIMATE TREE GAPS IN A PRECISION FOREST MANAGEMENT AREA THE AMAZON BASED ON CROWN MORPHOMETRY

description: ABSTRACT The precision forest management technique still has much to be improved with the incorporation of forest biometric techniques and forest profiling with airborne LIDAR. When planning the cutting of a tree in forest management, the volume to be produced for industry is estimated but not the area impacted by removal of the tree. The objective of the present study was to develop equations for the Amazon rainforest that are able to estimate the impact area of gaps from harvesting individual dominant and co-dominant trees based on the canopy morphology obtained through forest profiling. On two separate occasions profiles were made in an annual forest-production unit in the Antimary State Forest (FEA) in the state of Acre, Brazil. The first was done a few days before the start of logging in 2010 and the second was done after completion of harvest activities in 2011. With field measurements and processing of the cloud of LIDAR points, dendrometric and morphometric variables were obtained for the canopy in order to develop equations for estimating gap areas. After evaluation of the explanatory variables with the highest correlation with gap area, the method used considered all possible models and included 2-4 parameters. The explanatory variables that best represent the impact of clearings are volume of the crown (VCop) and crown-projection area (APC). Ten equations were selected, of which two were chosen for use; these had R2 aj &gt; 75% and Syx &lt;23%. The good fit of the equations demonstrates the potential use of LIDAR to obtain information for estimating in advance the gaps in the forest cover that will be created from harvesting trees of different sizes.

title: Reaction of lettuce genotypes to Lettuce mosaic virus-Most (LMV-Most) and characterization of the translation factor eIF4E

description: Abstract: The objective of this work was to evaluate lettuce genotypes for their reaction to Lettuce mosaic virus (LMV; Most-type, isolate AF-199) and variations of the eukaryotic translation initiation factor eIF4E. All inoculated genotypes were susceptible to LMV, which was detected by RT-PCR using specific primer pairs. However, the accessions 169501, 169501C, 172918A, and 162499 showed late development of symptoms that appeared only on the inoculated leaves. Sequencing of the coding region of eIF4E showed that these genotypes have an eIF4E0 (mol 0 ) standard typical for their susceptibility to LMV, indicating that the phenotype found is not correlated to nucleotide variations in this translation factor.

title: ESTIMATION OF HEIGHT OF EUCALYPTUS TREES WITH NEUROEVOLUTION OF AUGMENTING TOPOLOGIES (NEAT)

description: ABSTRACT The aim of this study was to evaluate the method of neuroevolution of augmenting topologies (NEAT) to adjust the weights and the topology of artificial neural networks (ANNs) in the estimation of tree height in a clonal population of eucalyptus, and compare with estimates obtained by a hypsometric regression model. To estimate the total tree height (Ht), the RNAs and the regression model, we used as variables a diameter of 1.3 m height (dbh) and the dominant height (Hd). The RNAs were adjusted and applied to the computer system NeuroForest, varying the size of the initial population (the genetic algorithm parameter) and the density of initial connections. Estimates of the total height of the trees obtained with the use of RNA and the regression model were evaluated based on the correlation coefficient, the percentage of errors scatter plot, the percentage frequency histogram of percentage errors, and the root mean square error (root mean square error - RMSE). Various settings which resulted in superior statistics to the hypsometric regression model were found. Connections had the highest correlation and the lowest RMSE% with a population size value of 300 and an initial density of 0.1 RNA. The NEAT methodology proved effective in estimating the height of trees in clonal population of eucalyptus.

title: Morphology and Phase Formation During the Solidification of Al-Cu-Si and Al-Ag-Cu Ternary Eutectic Systems

description: The microstructure of ternary alloys in the Al rich corner of the Al-Cu-Si and Al-Ag-Cu systems were analyzed in order to determine the solidification path in the different structural regions expected from the equilibrium phase diagram. The analysis was based on theoretical models developed in the literature for solidification of ternary eutectic system alloys under simple lever rule assumptions. Optical microscopy (OM), scanning electron microscopy (SEM) and energy dispersive X-ray microanalysis (EDAX) were used to study the microstructure formed in each case. The observations were consistent with model predictions: Al-Cu-Si system showed two binary eutectics: non faceted-non faceted (nf-nf) AlCu and faceted-non faceted (f-nf) AlSi, Al-Ag-Cu system showed 2 binary regular eutectics (nf-nf) and a ternary semi-regular Brick type eutectic. The results provided an example of a methodology for use in ternary and multicomponent alloys.

title: Frequency of ocular conditions in native Brazilians from Avaí City, São Paulo State

description: Abstract Purpose: To perform an epidemiological study of eye diseases in the population of four indigenous communities in the City of Avai in the state of São Paulo - Brazil: Ekeruá, Kopenoti, Nimuendaju and Tereguá. Methods: This is a prospective, cross-sectional, population-based study performed by the Medical Residency Program of the Center of Excellence in Ophthalmology (CEO-Bauru), including all the inhabitants of four indigenous tribes, between the months of March and April 2016. All participants were submitted to a complete eye examination that included refraction test and best-corrected visual acuity, external ocular motility and strabismus, measurement of intraocular pressure (IOP), color vision test, slit lamp examination and a complete evaluation of the fundus. Results: From a total of 584 natives from four villages, 377 (64.55%) attended the project. 283 appointments were performed at CEO - Bauru and 94 evaluations in the health center of Kopenoti village using a mobile ophthalmology unit. 48.54% of the participants were male and 51.46% female. The mean age was 32.03 ± 21.45 years. Our study found prevalence of pterygium of 14.05%, cataract of 6.63%, glaucoma of 1.85% and diabetic retinopathy of 1.59%. These numbers are higher than found in other epidemiological studies. Regarding refractive errors, 36.99% presented astigmatism, 4.24% simple myopia and 8.35% simple hyperopia. Conclusion: These information are extremely important because they show higher rates of eye diseases in a needy and remote population of urban health centers, and in need of medical care. It is noteworthy that all patients from this study who presented refractive errors, received glasses with the corrected refractive lenses.

title: Does Parkinson's disease start in the gut?

description: ABSTRACT Current understanding of the pathophysiology of Parkinson's disease suggests a key role of the accumulation of alpha-synuclein in the pathogenesis. This critical review highlights major landmarks, hypotheses and controversies about the origin and progression of synucleinopathy in Parkinson's disease, leading to an updated review of evidence suggesting the enteric nervous system might be the starting point for the whole process. Although accumulating and compelling evidence favors this theory, the remaining knowledge gaps are important points for future studies.

title: LEAF RESIDUE DECOMPOSITION OF SELECTED ATLANTIC FOREST TREE SPECIES

description: ABSTRACT Biogeochemical cycling is essential to establish and maintain plant and animal communities. Litter is one of main compartments of this cycle, and the kinetics of leaf decomposition in forest litter depend on the chemical composition and environmental conditions. This study evaluated the effect of leaf composition and environmental conditions on leaf decomposition of native Atlantic Forest trees. The following species were analyzed: Mabea fistulifera Mart., Bauhinia forficata Link., Aegiphila sellowiana Cham., Zeyheria tuberculosa (Vell), Luehea grandiflora Mart. et. Zucc., Croton floribundus Spreng., Trema micrantha (L) Blume, Cassia ferruginea (Schrad) Schrad ex DC, Senna macranthera (DC ex Collad.) H. S. Irwin and Barney and Schinus terebinthifolius Raddi (Anacardiaceae). For each species, litter bags were distributed on and fixed to the soil surface of soil-filled pots (in a greenhouse), or directly to the surface of the same soil type in a natural forest (field). Every 30 days, the dry weight and soil basal respiration in both environments were determined. The cumulative decomposition of leaves varied according to the species, leaf nutrient content and environment. In general, the decomposition rate was lowest for Aegiphila sellowiana and fastest for Bauhinia forficate and Schinus terebinthifolius. This trend was similar under the controlled conditions of a greenhouse and in the field. The selection of species with a differentiated decomposition pattern, suited for different stages of the recovery process, can help improve soil restoration.
