The adoption of the implementation of such systems has increased and with the permission of Brazilian legislation of the use of agroforestry systems in the recomposition of Legal Reserve and Permanent Preservation is of utmost importance studies demonstrating the characteristics of such systems and how much they resemble native forest environments, and whether in fact they can contribute to the recovery of degraded areas, allying preservation with income generation. In order to contribute to information on agroforestry systems, this paper aims to gather information on biodiversity agroforestry systems and their potential for area recovery and income generation, underpinning future systems deployments; to this end, two articles were drawn up. The first concerns "Diversity, structure and dynamics of arboreal species implanted in biodiversity agroforestry systems." For the realization of the article, were analyzed the floristic composition of four agroforestry systems which were divided into plots 10 m x 10 m (100m²). After this process, it was standardized 0.5 hectares (500m ²), that is, 50 plots in each agroecosystem, distributed at random. The presence of 96 species belonging to 37 families was contested, with a total of 3,766 individuals, highlighting SAFs 1 and 2 for their greater diversity; The characteristics raised demonstrate that the analyzed systems can assist in the recovery process of areas. In chapter 2 the focus is the analysis of "Arrangements of biodiversity agroforestry systems for Legal Reserve Areas, with economic viability. For composition of the arrangements were selected native species for diversity of the environment and exotic for income generation; For the assessment of economic viability, the preadsheet was used, considering a period of 20 years, the financial analysis indicated that the two arrangements of proposed SAFs proved economically viable, entertaining in the 2 System, the economic indicators presented values higher than the 1 System, being in the 1 System: VPL of R $12,12 VAE of R 1,702,08; TIR 27.66% and RB/C 1.30; already for System 2, the values were: LPV of 31.488.74; VAE of 4,348,46; 80.84% TIR and 1.50 RB/C. The pay-back time was also better for System 2, being 2 years, while for System 1 the time was 4 years. The results obtained with the two articles demonstrate that the use of agroforestry systems can be a viable measure both economically and for recovery of areas.

Hunt var. purpurea Autor(es): Salgueiro, Shirley Almeida Mendonça Primeiro Orientador: Silva, Rosilda Mara Mussury Franco Abstract: The objective of this work was to estimate air quality based on the vehicular flow of cities located at different altitudes in the Bodoquena microregion, in the state of Mato Grosso do Sul, Brazil. To this end, the micronucleus test was performed by means of the TRAD-MCN bioassay on young Buds of Tradescantia collected in the period between November 2018 in seven cities in the Bodoquena microregion, with different vehicle flow intensities. Meteorological parameters were evaluated and vehicles were counted to determine vehicle traffic in each city. The from the bioassay performed, relating environmental variables and altitude and using the Shuttle Radar topographic mission (SRTM) and processed in the Esri ArcGIS® software version 10.5.1 was able to map the area based on the Elevation Model. The analyses morphoanatomical were performed according to standard methodology. The measurements of thickness, length, width and fabrics and structures such as the upper cuticle, lower cuticle, upper face and lower face of the epidermis, hypodermis and mesophilic were Evaluated. The largest vehicular flow was found in the cities of Bodoquena, Guia Lopes Laguna, Jardim and Porto Murtinho. The time from 17:00 to 18:00 was the one that presented higher flow of vehicles. However, the highest frequency of mutagenic changes was found in the city of Guia Lopes, not differing from Bonito, Caracol and Jardim. Along biomonitoring was observed that the summer and autumn seasons were the ones that presented higher frequencies of micronucleus independent of the city evaluated. A correlation was observed between the frequency of micronuclei and the vehicular flow was low supporting the thesis that this micro-region although mutagenic changes are observed in T. pallida changes numerically are small when compared to other regions state of Mato Grosso do Sul. There was a variation in the thickness of the tissues/structures that varies between the different cities and seasons. In a way that tissues/structure were reduced for the cities of Nioaque and Porto Murtinho as to the anatomical and morphological aspects being that for the length and leaf thickness was not observed differences between the cities. In relation to the seasons of the year, it was observed that in autumn the thickness of the tissues/structures are smaller.

Schult Autor(es): Oliveira Junior, Pedro Cruz de Primeiro Orientador: Formagio, Anelise Samara Nazari Abstract: Objectives: Palicourea crocea showed promising results in chemical investigations, which include the isolation of alkaloids; however, no biological analyses have been conducted so far to evaluate the antioxidant, anti-inflammatory and antinociceptive properties. Methods: The chemical composition of the methanolic extract from P. crocea leaves (MEPC) were investigated using high performance liquid chromatography (HPLC/PAD) method, and the concentrations of total phenolics, flavonoids, flavonols and condensed tannins also were determined, so is the isolation the principal alkaloid (PC-1) of this plant. The antioxidant activity of the MEPC and PC-1 were evaluated for free radical scavenging activity using the DPPH and ABTS; lipid peroxidation using malondialdehyde (MDA). MEPC (300, 100 and 50 mg/kg) and PC-1 (50 and 10 mg/kg) also were tested in anti-inflammatory effects in carrageenan-induced mice paw edema and anti-hyperalgesic for cold sensitivity and mechanical hyperalgesia. Key findings: MEPC showed highest concentrations of phenolic and flavonoids compounds (≤ 800.35 mg/g), revealed by HPLC-PDA analysis the caffeic acid, ferulic acid, rutin and quercetin. The MEPC displayed potent antioxidant activity for ABTS radical (IC50 = 68.5 µg/ mL) and MDA (74%). The oral administration of the MEPC (300, 100 and 50 mg/kg) and croceaine A alkaloid PC-1 (50 and 10 mg/kg) exhibited an anti-oedematogenic effect in Cg-induced paw oedema in 2 and 4h. Also reduced significantly the mechanical hyperalgesia and the cold response to acetone in mice, at 3 and 4 h after injection. Conclusions: For the first time, evaluating antioxidant and systemic anti-inflammatory and antihyperalgesic activities from P. crocea.

The poison produced by the acid gland, which presents phenotypic variations of different categories, is stored in the reservoir and released when the sting occurs. The phenotypic variations of the gland suggest that the amount of poison varies according to its length and this characteristic, in turn, varies according to the genotype to individual (worker). Small glands (smaller) (5.97 mm) would present a recessive homozygote genotype and large glands (larger) (10.90 mm) a dominant homozygote genotype, being under the action of genes with Mendelian effects and the variations would occur according to the combination of the effect of these genes and another pair of "modifier genes" that would influence the final phenotype observed for the glands. In the urban area of the city the presence of africanized honey bees with different phenotypes can be detected as to the observable variations in the poison gland, resulting in productions of greater or lesser quantity of the one. With it, the goal was to investigate in the urban area of the city of Dourados-MS, the genotypic characteristics of these bees, through the evaluation of the phenotypic diversity of the referred structure. To this, the city was spatially divided into four quadrants, where in each of it, 500 Africanized worker bees were captured by active collection with the aid of an entomological network. These bees were taken to the FCBA/UFGD Beekeeping Laboratory (LAP), dissected using a Zeiss stereomicroscope with 16X increase. After, the glands were fixed with colorless enamel on a histological blade and subsequently, besides other characteristics, their total glandular length (CGT) and the presence or absence of branching have been measured. Another 50 Africanized bees were also collected in each quadrant, the same methodology was applied, but were separated from the acid gland, the sting apparatus and the poison reservoir. The weight of the dry poison inside the reservoir was measured and compared to the CGT of the corresponding producing gland. The predominance of small glands (GP) on the quadrants 1, 2 and 3 was obtained in the first 10 stage, on the quadrant 4 the predominance was large glands (GG). In the second stage, the largest glands, with dominant genes were found in quadrants 4, 2 and 3 respectively, with GG percentages of 78%, 70% and 54%, GP were more frequent in quadrant 1, with a total of 52%. The glands presented stoked production in the reservoir in a varied quantity, according to the phenotype presented according to the suggested genotype; larger glands, greater amount of poison, smaller glands, smaller amount produced. In both phases, the highest rates of forks were recorded in the quadrants with the higher rate of large glands, and also the higher amount of poison stored, which leads us to conclude that larger glands with the presence of bifurcation tend to present higher production of poison.
