title: Water urgency: urban interventions in watershed areas

description: The relations between urban and environmental policies represent a great challenge to the formulation of answers to urban pressures versus environmental preservation. In watershed areas of the Metropolitan Region of São Paulo, the dimension of this challenge is particularly significant, mainly because the environmental and urban policies face spontaneous and precarious occupation processes in protected areas. This article sets the panorama of the institutionalization of public policies – urban and environmental – in the watershed area of the Billings reservoir, and investigates the case of the city of São Bernardo do Campo, emphasizing the implementation of urban planning tools that integrate housing and environment. It is possible to conclude that the challenges to the recovery of watershed areas go beyond the imposition of legal landmarks. They primordially depend on innovative intervention strategies that involve the civil society and may signal a real transformation of the reality faced by protected drainage basins.

title: Cadmium Tolerance During Seed Germination and Seedling Growth of Schinus molle (Anacardiaceae)

description: Abstract Cadmium (Cd) is one of the most toxic elements to plants, so Cd-tolerant trees should be used in reforestation or remediation systems. In this study the effects of Cd on seed germination and early seedling growth were evaluated in Schinus molle plants. Seeds of S. molle were treated with Cd at concentrations of 0 (control), 0.01, 0.02, 0.05, and 0.125 mM using Cd(NO3)2. Seed germination parameters and seedling growth traits were evaluated 33 days after the experiment started. Seeds and roots were sampled for anatomical evaluation and processed with plant microtechniques. No effects of Cd were found on the germination percentage of S. molle seeds. However, seedlings’ shoot and root fresh masses and lengths increased with Cd treatment. Cadmium increased root cortex and endodermis thickness and reduced the percentage of vascular tissues in seedlings. Schinus molle seeds and seedlings thus showed tolerance to Cd related to anatomical adaptations.

title: Genetic Diversity Between and Within Astrocaryum acaule Mart. (Arecaceae) Populations

description: Abstract This article sought to assess the genetic diversity within and between natural populations of Astrocaryum acaule by means of AFLP markers. Ninety individuals were sampled in three populations located in Manaus (state of Amazonas) across regions with different intensities of anthropogenic activity. Two clusters were differentiated by means of dendrograms and Bayesian cluster analysis, the first consisting of individuals from the Tarumã-Açu population in an intensely agricultural region, and the second, of populations from UFAM and Tupé conservation areas. The physical isolation of A. acaule populations has resulted in good conservation of its genetic identity, since anthropogenic activity is an important modifier of the genetic diversity of natural populations. Genetic diversity was higher within populations (74.58%) than between them (25.42%), which means that we have to collect representative samples from each of the genetically distinct groups for genetic conservation of the species. Therefore, in situ conservation is recommended.

title: Antibacterial activity and stability of microencapsulated lemon grass essential oil in feeds for broiler chickens

description: SUMMARY The antibacterial effect of microencapsulated lemon grass (Cymbopogon citratus) essential oil on strains of Escherichia coli (ATCC8739), Staphylococcus aureus (ATCC 6538) and Salmonella enterica subsp. enterica (ATCC 6017), and the stability of this oil in feeds for broiler chickens were evaluated. The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were determined by the macrodilution method, using the microencapsulated lemon grass essential oil at concentrations of 160 μL mL−1, 80 μL mL−1, 40 μL mL−1, 20 μL mL−1, and 10 μL mL−1. The oil concentration of 80 μL mL−1 presented the best results against the three bacteria evaluated. Samples of 200 g of feed mixed with 120 μL g−1 of the microencapsulated lemon grass essential oil was stored to evaluate the oil stability. Feed without microencapsulated lemon grass essential oil was prepared as control. The oil remained active for seven days, with significant reduction of S. aureus (3.08 CFU), E. coli (3.01 CFU), and S. enterica (3.10 CFU). The microencapsulated lemon grass essential oil at concentration of 80 μL mL−1 had antibacterial effect against the E. coli, S. enterica and S. aureus, and maintained stability of the feed for seven days, even with presence of organic matter, which is source of nutrients for pathogens.

title: On the use of the P300 as a tool for cognitive processing assessment in healthy aging: A review

description: ABSTRACT Changes in patterns of performance for the cognitive functions of memory, processing speed, and focused attention are expected in old age. Objective: The main goal of this systematic review was to analyze the use of ERP in healthy elderly in studies evaluating the P300 components. Methods: A systematic review was carried out based on recommendations for nursing research on the databases LILACS, PsycINFO, PubMed, SCOPUS and Web of Science. Results: 26 studies involving 940 healthy elderly were identified, most of which sought to identify and determine the influence of age on the P300. Conclusion: Although there is consensus in the literature that P300 latency is significantly longer in elderly with psychiatric disorders compared to healthy elderly, it was not possible to conclude P300 associations with gender, education and other cognitive tests.

title: Evaluation of Vegetation after Four Years in a Caatinga Fragment in the State of Sergipe, Brazil

description: Abstract The comparison of vegetation at two different moments allows for recognizing the stability of plant communities. The structure and floristic composition of a Caatinga fragment in the municipality of Poço Verde, state of Sergipe, were evaluated after four years (2011-2015). Sampling was performed through 30 plots of 20 m × 20 m, considering individuals with circumference at breast height ≥ 6 cm. Despite the increase in density (0.79%) and basal area (4.82%), changes in floristic composition, in Shannon-Wiener diversity (from 3.33 nats.ind-1 to 3.30 nats.ind-1) and in Pielou equability (from 0.78 to 0.80) were small. None of the structural parameters evaluated (richness, density, basal area, importance value and Shannon-Wiener diversity) significantly differed between evaluation periods. The vegetation remained stable over time, tolerating current anthropization levels and enabling the use of its natural resources through planned management.

title: MAGNETIC SUSCEPTIBILITY AS INDICATOR OF SOIL QUALITY IN SUGARCANE FIELDS

description: ABSTRACT Sugarcane management practices (unburned cane - UC and burned cane - BC) interfere with dynamics of soil magnetic properties. This study focused on determining the potential of magnetic susceptibility as soil quality indicator in areas under sugarcane cultivation. The experiment area is on the limit between basalt from São Bento Group, Serra Geral Formation, and sandstone from Bauru Group - Adamantina Formation. Twenty soil samples were collected from two management areas (burned and unburned sugarcane prior to harvest) at a depth range of 0.0-0.2 m. Local soil was classified as eutroferric Red Latosol (Oxisol), with highly clayey texture. Chemical and physical properties, CO2 emissions and magnetic susceptibility (MS) in air-dried fine earth (MSADFE), total sand fraction (MSTS) and clay fraction (MSCF). The magnetic signature from MS was effective in identifying changes of physical, chemical and mineralogical traits in Latosols under burned and unburned sugarcane crop. The information provided here can guide further studies on the genesis of minerals with magnetic expression in environments and exposed to fire burning.

title: Hydroenvironmental characterization of springs

description: Abstract Springs consist of an upwelling of groundwater from which water flows. This water then forms the drainage network. The negative environmental impacts caused in any portion of the basin may affect the quantity and quality of water. This study characterized the springs of Itanguá watershed, Capão Bonito, SP, considering their types, their conservation status, and the presence of negative environmental impacts. As for the type, springs were classified as “point” or “diffuse” and, regarding conservation status, they were ranked as “excellent”, “good”, “fair”, “bad” and “very bad” based on macroscopic evaluation. Nineteen springs were identified and 15 visited; of these, nine were classified as “point”, and six as “diffuse.” With respect to conservation status, two springs were classified as “excellent”, 12 as “good”, and one as “fair”. The presence of exotic species was observed by macroscopic evaluation, such as animal (boar) and vegetation (Pinus spp.). The lack of vegetation in “permanent preservation areas” was the most frequently observed environmental impact found. The methods used were efficient as a first analysis of the situation of the springs and to provide information to support programs to improve water conservation in the Floresta Nacional de Capão Bonito, SP.
