title: Size and vigor of Anadenanthera colubrina (Vell.) Brenan seeds harvested in Caatinga areas

description: Abstract: Angico is a species found in several environments in Brazil, with several applications. It is used in the timber industry and mainly in folk medicine. In order to verify a variation in the biometric characteristics and the quality of seeds from different mother-plants in different harvesting years, the following variables were studied: moisture content, diameter, density, electrical conductivity, fresh and dry matter of seedlings, germination percentage and kinetics, in a completely randomized design with a 2x3 factorial arrangement (lots x size). The obtained results showed that angico seeds from different lots showed different physiological quality, possibly due to the climate variations to which mother-plants were submitted in the different years. Seed size directly interferes with seedling growth under both controlled and greenhouse conditions, and it can be used as a vigor indicator for angico seeds.

title: Environmental Violation Fines Growth in the Northern Region of Santa Catarina State, Brazil

description: ABSTRACT This study aimed to diagnose the environmental infractions that occurred in the northern region of Santa Catarina State (Southern Brazil). The environmental infractions were classified by category and by violation activities concerning the hydrographic regions of Canoinhas Plateau and Baixada Norte from 2014 to 2018 to assess the growth and causes of a diagnosis regarding the environmental damages occurrences. Results indicated that the major illegal environmental practices registered in both region are related to environmental violations regarding the damage caused in native vegetation, and these damages are caused without authorization of the competent environmental authority. In addition, it was also important to note the activity of maintaining birds in captivity and of functioning of potentially pollutant activities or establishments that do not have a license of the competent regional environmental agencies. Therefore, efforts from the Environmental Policy should be directed to implement a forest monitoring system using remote sensing technology apart from starting a stronger cooperation with municipal authorities from Santa Catarina State by promoting Environmental Monitoring Programs (EMP).

title: Dendrometric Analysis of Early Development of Eucalyptus urophylla x Eucalyptus grandis with Gypsum use Under Subtropical Conditions

description: ABSTRACT Gypsum can be used as a source for calcium (Ca) and sulphurum (S) for plants, as well as an acid, that is, a natural soil conditioner. Aiming to determine the influence of gypsum on the development of Eucalyptus urograndis in Brazil, an experiment was conducted at two locations in Paraná State. Experiments were conducted with rates of 0, 0.3, 0.6, 1.2, 2.4, 4.8 and 9.6 Mg ha-1 to verify the method of broadcast planting in a randomized block design with four repetitions. Diameter and height of plants were measured every six months and volume was determined after 36 months. There was a difference in Eucalyptus growth between the two areas, possibly related to differences in planting season and climate. Gypsum did not influence on the dendrometric growth of Eucalyptus trees. The lack of a response to gypsum, as a source of Ca, S and soil conditioner, was discussed based on soil type, Eucalyptus tolerance to soil acidity, and climatic conditions in the period evaluated.

title: Terracing Recovers the Quality of a Riverbank Soil Degraded by Water Erosion in Brazilian Semiarid

description: ABSTRACT Soil physical-hydraulic properties are among the most important indicators for evaluating soil quality. This study aimed to experimentally demonstrate how the construction of terraces can affect physical-hydraulic properties of a soil degraded by water erosion on the banks of the Salitre river, tributary of the São Francisco river. An area in advanced stage of degradation by water erosion was delimited for the construction of a level bench terrace. The experiment was conducted for two years. Soil physical-hydraulic properties were determined before and after terracing. Time-domain reflectometry (TDR) was used to measure soil water storage (mm). This study demonstrated that terracing positively affected soil physical-hydraulic properties in the previously degraded area, allowed the increase in the retention and availability of water in the soil, thus is an ecologically beneficial practice for recovery of degraded soils on the banks of the Salitre river.

title: Copper Accumulation and Distribution in Two Arboreal Species of the Atlantic Forest

description: ABSTRACT This study aimed to evaluate the accumulation and distribution of copper (Cu) in the pioneer tree Schinus terebinthifolius R. (aroeira) and non-pioneer tree Eugenia uniflora L. (pitanga) submitted to different concentrations of copper. The plants received 40 mL of Hoagland & Arnon (1950) n. 1 nutrient solution modified with 0.00032, 0.0032, 0.032 and 0.32 mM Cu2+ applied to the soil. We analyzed biomass, biometry and Cu contents in plants and the concentration of Cu in soil. Cu concentration in the soil contaminated with 0.32 mM Cu2+ was higher than other treatments. Neither species showed characteristics of plant phytotoxicity. However, the two species did exhibit different physiological responses to Cu; S. terebinthifolius accumulated the metal only in roots, while E. uniflora accumulated Cu in roots and leaves. The highest Cu concentration in soil was observed in the treatment with 0.32 mM Cu2+. Outstanding to foliar accumulation, E. uniflora could be used for biomonitoring.

title: Different Patterns Of Nutrient Cycling In Contiguous Phytophysiognomies Of Atlantic Forest, Brazil

description: ABSTRACT The present study aimed to evaluate fine aboveground litterfall, deposition of nitrogen and phosphorus from total litterfall and leaf litter decomposition in areas of tall forest (Mata Alta) and low forest on sandy soils (Mussununga) in southeastern Brazil. Fine litterfall was collected monthly for two years (from June/2007 to May/2009) in 10 conical collectors (0.25 m2) in each phytophysiognomy (1 ha plots). The material was subsequently separated into leaves, branches, flowers and fruits, and unidentified material. Leaf decomposition rates were evaluated using 15 litterbags, three of which were collected every 30 days. Higher litterfall occurred in both phytophysiognomies during the rainy season, with leaves predominating. The lowest litterfall, nutrient input, and leaf litter decomposition values appeared to be nutrient conservation strategies, contributing to the ecological functioning of the Mussununga where soil fertility was lower than in the Mata Alta.

title: Dietary total antioxidant capacity as a preventive factor against depression in climacteric women

description: ABSTRACT Depression is characterized by physical or psychological distress and in many cases can lead to suicide. Objective: to assess the prevalence of depression and its possible relationship with dietary total antioxidant capacity (DTAC) and nutritional parameters in climacteric women participating in an extension university program in a Southern Brazilian city. Methods: data were obtained through questionnaires and anthropometric measurements. Diet was assessed using a 24-hour dietary recall. The Beck Depression Inventory (BDI) was used to assess the intensity of symptoms of depression. Results: DTAC of the population ranged from 435.60 to 4502.62 mg VCE/day. Among the most consumed antioxidant food/beverages, coffee ranked highest. Polyphenols were found to be directly linked to the antioxidant capacity of fresh foods (r=0.905; p=0.0001). Prevalence of depression in the population was 44%, and depressed women had lower intake levels of polyphenols (p=0.022; Cohen's d=0.80), and vitamin B6 (p=0.038; Cohen's d=0.65), vitamin A (p=0.044; Cohen's d =0.63), and vitamin C (p=0.050; Cohen's d =0.61). There was a significant negative correlation between BDI scores and polyphenol intake (r=-0.700; p=0.002). Conclusion: these results may contribute to a better understanding of the recommended dietary antioxidant intake as an adjuvant for preventing depression in women.

title: Comparison between Resistograph Analysis with Physical Properties of the Wood of Brazilian Native Tree Species

description: ABSTRACT There is just little information about the technological aspects of the wood of Brazilian native tree species, which limits their suitable use. The objective of this study was to evaluate the resistograph amplitudes of the wood from six native tree species in different wood density classes, and correlate them with their wood densities to demonstrate the efficiency of this nondestructive technique. The results of the resistograph analysis divided the species into three classes. Analyses of basic and bulk densities of their wood showed statistically significant differences among the evaluated samples that divided them into four classes. The comparison of resistograph method and observed densities showed only a slight difference among the density classes. Therefore, it was found in this study that resistograph analysis may be used for explaining wood properties as well as achieving satisfactory correlations with their actual values, especially the physical properties of species with high wood density.

title: Reuni and University Expansion in UFMG from 2008 to 2012

description: Abstract: This article aims to analyse how well the goals of Universidade Federal de Minas Gerais (UFMG) presented to the Ministry of Education (MEC) in 2008 for the Program of Support to Restructuration and Expansion Plans (Reuni) were achieved in 2012, as well as the changes that occurred in the institutional context as a result of the university expansion induced by this program. Documents related to the REUNI program were examined and the institutional data published by UFMG in its website and in its Annual Report from 2011 were analysed. The results of this research show that UFMG fulfilled almost entirely its proposals for new programs and expansion of vacancies. However, unexpected events and worsening of critical situations have arisen and require attention of university management.

title: PHYSICAL AND PHYSIOLOGICAL ATTRIBUTES OF SAVED COWPEA SEEDS USED IN THE BRAZILIAN SEMI-ARID REGION

description: ABSTRACT This study evaluated the physical and physiological attributes of saved cowpea seeds (Vigna unguiculata L. Walp.) used in the Brazilian semi-arid area and compared them with certified seed varieties. The study tested 37 saved seed samples from the state of Rio Grande do Norte and two varieties of certified seeds (“BRS Guariba” and “BRS Pujante”) from the production field of Embrapa Products and Market, Petrolina, PE, Brazil. The seeds were tested for moisture, hectoliter weight, weight of 1,000 seeds, and physical purity to evaluate the physical quality. Germination, first germination count, field emergence, emergence rate index, shoot dry mass, and accelerated aging were tested for physiological quality. The saved cowpea seeds showed great differences, suggesting the influence of genetic variability and different growing environments. The use of saved cowpea seeds by small farmers in the semi-arid areas of Northeastern Brazil is impractical, because these seeds have inferior physical and physiological qualities compared to certified cowpea seeds.

title: Evaluation of contamination risk of aquifers of the Limoncocha Biological Reserve, Ecuadorian Amazon Region

description: Abstract Groundwater is one of the main supply sources of the inhabitants of Limoncocha and Pompeya parishes, located in the Ecuadorian Amazon region. The Limoncocha Biological Reserve (Spanish acronym, “RBL”) is located in this region, and its area of influence (AI) has an underground ecosystem which receives a substantial supply of water from external flows. Traditionally, groundwater has been considered "protected" by the subsoil. However, the disposal of stable pollutants from human activities in areas favorable to infiltration could cause the contamination of this resource, risking the health of the population and the reserve's sustainability. Consequently, it was proposed that an assessment be done of the risk of groundwater contamination of the RBL and AI by overlapping the vulnerability map of the aquifer using the GODS method with an inventory of pollutant loads by the POSH method. In this way, measures for the protection of this resource might be prioritized. In most of the study area there was no danger of groundwater contamination. Nevertheless, areas of moderate and high risk were found. Measures to prevent the deterioration of the underground water quality were therefore proposed.
