Item Parâmetros fitossociológicos e índice de perfomance na arborização de ruas de Recife, Pernambuco(2025-02-10) Novais, Maria Eduarda Silva de; Lima Neto, Everaldo Marques de; http://lattes.cnpq.br/6791561445213969; http://lattes.cnpq.br/1071037415624656The phytosociological study of urban trees is an important tool for planning, maintaining and managing tree planting in cities. Understanding the floristic composition and phytosociological structure of urban environments is fundamental to understanding the dynamics of vegetation, as well as providing support for the implementation of actions aimed at conserving and improving diversity in these areas. With this in mind, the aim of this study was to analyze the adaptation and performance of the species present in the street trees of Recife-PE. The research was carried out on 4 (four) sample units measuring 350 meters x 560 meters, randomly selected from the inventory of street trees carried out by Biondi (1985) in Recife, Pernambuco. The species present on the sidewalks were identified and the phytosociological parameters, Absolute and Relative Frequency (AF and FR), Absolute and Relative Dominance (DoA and DoR), Absolute and Relative Total Density (DT, DA and DR), Absolute and Relative Importance Value (VI and VI%), and the Performance Index (IPE) were estimated. A total of 528 individuals were counted, distributed among 59 species belonging to 19 families. It was observed that 67,86% are of exotic origin from Brazil, which is one of the main causes of biodiversity reduction. The species with the highest number of individuals were Senna siamea (87 individuals), Ficus benjamina (64 individuals) and Adonidia merrillii (53 individuals). The phytosociological analysis showed that Pithecellobium dulce was the most dominant (19,99%), followed by Terminalia catappa (14,31%) and Senna siamea (13,85%). In erms of relative density, Senna siamea (21,48%), Ficus benjamina (16,79%) and Pithecellobium dulce (6,67%) showed a lower diversity of species in the areas studied. The VI was highest for Senna siamea (13,40%), followed by Ficus benjamina (10,97%) and Pithecellobium dulce (10,11%). The species with IPE above 1,0 were Handroanthus impetiginosus, Hymenaea courbaril, Schinus terebinthifolia, Apeiba tibourbou, Cassia fistula, Cassia javanica, Genipa americana and Bauhinia monandra, which continue to be included in Recife's afforestation. It is recommended that measures be taken to introduce species of native origin, and possibly to gradually replace individuals, helping to reduce the concentration of individuals in a few species, with the species Handroanthus impetiginosus and Bauhinia monandra, which were promising in relation to the values for IPE and VI%.Item Diagnóstico dos viveiros de mudas florestais no município de Gravatá - PE(2024-10-03) Lima, Pollyana Gomes da Silva; Freitas, Eliane Cristina Sampaio de; http://lattes.cnpq.br/7525975084334972; http://lattes.cnpq.br/3458909580899001Considering that the current supply of native tree seedlings is not compatible with market growth projections for the coming years, the need to increase production to meet potential oration sector, environmental regularization, and possible supply to one of Pernambuco's furniture hubs. In this sense, this work aims to diagnose forest seedling nurseries in the county of Gravatá and to propose the development of a project to implement a new forest nursery in the rural area of the county. Therefore, 11 nurseries that produce and/or resell forest seedlings in the region were found to be analysed and interviewed, of which 5 agreed to respond to a questionnaire that aims to analyse their operating profiles and identify productive aspects; generating an information base for a SWOT analysis that results in an action plan, which brings an arrangement of suggestions coherent with the local reality supporting the aim of the study and substantiate the design, which was modeled using SketchUp 2019 software. The study showed that the forest nurseries present in Gravatá have a timid performance regarding seedling production, with 80% of them only resellers, making it clear that seedling production is not yet seen as a significant business in the municipality. Regarding infrastructure, the forest seedling nurseries in the municipality have basic infrastructure components. Regarding species diversity and productive capacity, there are seedlings produced and/or resold are mostly exotic species, coming from nurseries with an annual capacity of up to 10 thousand seedlings, whose main destination is local landscaping. The main problems faced were technical difficulties in cultivation and low availability of seeds. Aiming to give greater robustness to the municipality's forest nursery framework, as well the supply of potential demand for forest seedlings in the coming years are met, the project to implement a new nursery was taken as a starting point, with an annual production capacity equivalent to a total of 3,488 to 8,208 seedlings produced in bags and tubes, based on the considerations brought by the action plan generated from the analysis carried out.Item Crescimento e qualidade de mudas de Piptadenia stipulacea (Benth.) Ducke, em diferentes recipientes e doses de fertilizante misto(2024-09-12) Souza, Thallyta Valentin dos Santos de; Freitas, Eliane Cristina Sampaio de; http://lattes.cnpq.br/7525975084334972; http://lattes.cnpq.br/1375547405957419In 2022, Brazil suffered a neduction of 2.05 million hectares of native forest, the Caatinga biome, in tum, lost the equivalent of 140.637 hectares. This highlights the urgency of actions to curb environmental degradation and promote conservation. It is vital to invest in research on native forest species to fill technological gaps, meet the demand for seedlings and drive sustainable development. Piptadenia stipulacea (Benth.) Ducke, a species native to Brazil, is a recommended option for recoverins degraded areas in the Caatinga. Therefore, the objective o£ this work is to evaluate the influence of the volumetric capacity of containers for the production of seedlings such as tubes and polyethylene bags, combined with different doses of NPK, on the growth and quality of seedlings of Piptadenia stipulacea (Benth.) Ducke. The study was carried out in the forest nursery of the Forestry Science Department of the Federal Rural University of Pernambuco (UFRPE), from November 2022 to March 2023. Three containers were tested for the production of seedlings: a 120 cm3 tube, a 280 cm3 and plastic bag of 3449 cm3 (20 cm x 30 cm) and four doses of NPK (4-14-8): 0; 2.0; 4.0; 6.0 Kg/m3. The analyzes of height and diameter of the stem were monitored monthly and a destructive analysis was performed at the end of the 120 days. The results indicated that the reduction in container volume caused a decrease in dry mass, diameter and height. Increasing NPK doses had a significant effect on recipient height and stem diameter. For the robustness index, the dose of 2 kg/m3 obtained the best performance. In view of the results, the use of polyethylene bags with the addition of 2 kg/m3 of NPK is recommended for the production of jurema branca seedlings.Item Reguladores de crescimento vegetal no enraizamento de miniestacas de araçá (Psidium cattleyanum Sabine)(2024-03-05) Amorim, Emanuel Regis Rodrigues de; Gallo, Ricardo; Sousa, Moema Barbosa de; http://lattes.cnpq.br/1125900782225064; http://lattes.cnpq.br/5160912065817980; http://lattes.cnpq.br/2530254056222729Item Planejamento da arborização urbana: estudo de caso da Avenida Duque de Caxias, São Lourenço da Mata - PE(2024-10-01) Cravo, Amanda Clarinda de Melo; Lima Neto, Everaldo Marques de; http://lattes.cnpq.br/6791561445213969This study focused on urban tree planning along Duque de Caxias Avenue, considering its feasibility and associated costs. The objective was to evaluate the physical conditions of the road and specific challenges, following the guidelines of the Urban Tree Planting Manual of Recife. Small-sized species suitable for sidewalk widths and wire heights were selected, essential to mitigate risks and reduce seedling mortality rates. The methodology included a detailed survey of available planting spaces, identifying 179 viable intervals, albeit limited by the scattered presence of urban elements such as poles and signage boards. The results highlighted the need for 2130 seedlings to cover the planned demand, considering a mortality rate of 50%. Cost assessments from nine local nurseries revealed budgets ranging from R$ 383,400.00 to R$ 440,200.00, emphasizing the complexity and economic challenges associated with acquiring seedlings in a region with scarce available native species. Additionally, a significant gap was identified in the supply of native species seedlings in local nurseries, underscoring the importance of effective policies for urban biodiversity conservation and encouragement of local seedling production. It is concluded that integrated and participatory planning is crucial for the success of urban tree planting initiatives, actively involving local communities, government agencies, and research institutions. This approach not only contributes to improving urban quality of life but also strengthens city resilience in the face of environmental challenges. This study not only provides relevant information for the practical implementation of urban tree planting projects but also highlights the ongoing need for adaptation and innovation in urban policies to promote greener and more sustainable urban environments aligned with sustainable development goals.Item Distribuição espacial da fauna edáfica em topossequência sobre um remanescente de floresta ombrófila densa em Pernambuco(2024-09-27) Santana, Augusto Guilherme Caldas de; Lima, Tarcísio Viana de; http://lattes.cnpq.br/0814281560377954Soil is considered a fundamental component as it induces the dynamic processes that shape the growth and development of the biological heritage of different terrestrial ecosystems. This biotic structure is represented by plants, animals, microorganisms, and soil fauna. In the specific case of soil fauna, there is significant morphological and functional diversity among these organisms, which are classified according to their respective sizes or body diameters and the ecological roles they play in the soil. Therefore, the objective of this work was to diagnose and evaluate the spatial distribution of soil fauna over a remnant of Dense Ombrophilous Forest, according to its toposequential exposure. The studies were conducted at Dois Irmãos State Park (Pedi), Recife-PE, at two moments: the rainy season (August) and the dry season (January). To carry out the activities, the vegetational cover was divided into three thirds (lower, middle, and upper), where simple samples of leaf litter and soil were collected to a depth of 5 cm. These materials were sent to the Forest Defense Laboratory at the Federal Rural University of Pernambuco (UFRPE) for manual sorting, initially of the macrofauna and then of the mesofauna, using Berlese-Tüllgren funnels to evaluate ecological structural characteristics. For data analysis, the ecological indices of Shannon-Weaver, Pielou, and Simpson were applied, with results showing a higher abundance of individuals in the lower third and in the leaf litter layer during the rainy season, with a predominance of the order Hymenoptera, but greater species richness in the upper third, indicating higher diversity in the leaf litter of this section. The dry season had more individuals than the rainy season, suggesting that the action of rain influences density in the different thirds of the toposequence, with greater accumulation in the lower third due to its lower altitude. The ecological indices indicated that the highest diversity is concentrated in the leaf litter of the upper third, as observed in the rainy season. Microclimatic data showed higher temperatures in the upper third, providing further support for the greater diversity present there. Hymenoptera was the taxonomic group with the highest presence in both periods, followed by Blattodea, Araneae, Chilopoda, and Coleoptera. The cluster analysis demonstrated that the dry season had greater similarity among the thirds, considering leaf litter and soil, than the rainy season.Item Fertilização potássica no crescimento de mudas de Eucalyptus camaldulensis Dehnh. sob limitação hídrica(2024-03-04) Luna, Andressa Cristina de; Freitas, Eliane Cristina Sampaio de; http://lattes.cnpq.br/7525975084334972; http://lattes.cnpq.br/8800788371861007The objective of this study was to evaluate the effect of potassium fertilization on the growth of Eucalyptus camaldulensis Dehnh seedlings under water limitation. The sowing was done with improved seeds of E. camaldulensis Dehnh in 80 tubes of 55 cm³ each. The seedlings were grown in full sunlight, and topdressing fertilization with macro and micronutrients, along with different doses of potassium (K), using potassium chloride (KCl) as a source, was applied. After the potassium fertilization was completed, measurements of height (H) and collar diameter (CD) were taken to standardize the seedlings according to each treatment (K dose), and they were transplanted into 5 dm³ capacity pots filled with a substrate composed of 70 % subsurface soil and 30 % commercial substrate. The treatments consisted of a factorial of two irrigation regimes (with and without suspension) by five levels of topdressing fertilization with K (0, 75, 150, 225, and 300 mg dm - ³), arranged in a completely randomized design with 4 repetitions, each pot composing a sample unit. After 15 days of transplantation, irrigation was suspended in half of the pots for 21 days, and the number of leaves (NL) was counted, along with recording visual symptoms of water stress during this period. At the end of the experiment, new measurements of height (H), collar diameter (CD), shoot dry matter (NL) were taken, growth increments were calculated, and stomatal density, chlorophyll index, relative water content, and dry matter were determined. Using the data of height (H), collar diameter (CD), shoot dry matter (SDM), root (RDM), and total (TDM), seedling quality ratios were calculated: SDM/RDM, H/CD, and Dickson Quality Index (DQI). The data were analyzed using analysis of variance (p<0.05), and those indicating significant interaction were subjected to regression analysis within the qualitative factor. Analyzing the statistical data, it was observed that potassium fertilization positively influenced the initial growth of the seedlings in all treatments, with the estimated optimum dose being 286 Kg dm -3 of K. The result of the variables with the factors of K doses and irrigation of Eucalyptus camaldulensis Dehnh seedlings showed a significant difference of 5% only for irrigation.Item Panorama da arborização urbana no Brasil e dos recursos florais oferecidos para a manutenção das abelhas(2022-12-12) Lidizio, Rebeca Kneipp; Parizotto, Daniele Regina; Costa, Pedro Eugenio Silva da; http://lattes.cnpq.br/5781652413151836; http://lattes.cnpq.br/6991049107988724; http://lattes.cnpq.br/5758118946730310Urban forestry has a primordial role in the quality of life and environmental comfort of its inhabitants. In Brazil, the discussion about planning afforestation has been growing in recent years, although synchrony with ecological aspects is still quite outdated. Therefore, this study aimed to present an updated of urban forestry in Brazil through a survey of the country's capitals. For this, afforestation manuals, master plans and afforestation guides from Brazilian capitals were consulted, resulting in more than 400 indicated species from 70 botanical families. Among the most indicated species, predominate species from seven families, with the genera Handroanthus and Tabebuia being the most indicate in Brazilian capitals. The results demonstrate that the official documents consulted are outdated and the also a low diversity of indicated species. The floral visitors for the indicated species belong 23 genera of bees, the majority being large bees of Apinae subfamily. The data show the need to diversify of species used in urban afforestation in Brazil and the inclusion of information regarding the floral resources. Finally, it is necessary to promote discussions that allow the inclusion of information about floral visitors in afforestation manuals. The diversification of tree species will promote the maintained of pollinators and the same time will help the health of plant species.Item Utilização de imagens SRTM na obtenção de dados altimétricos para o município de São João do Sabugi - RN(2024-08-13) Fabrício, Jefferson José Azevedo; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585The analysis of morphometric characteristics such as area, perimeter, slope, altitude, drainage density, among others, are fundamental in the development of environmental studies. The physical and biotic characteristics of a given location play an important role in decisionmaking. In this sense, the development and improvement of techniques together with geotechnologies for morphometric characterization have been the subject of study in several parts of the world, and promote relevant results. In view of the above, the present study aimed to perform the morphometric characterization of the municipality of São João do Sabugi - RN, using data from the ALOS PALSAR Satellite, integrated and processed in a GIS environment. The spatial data obtained were subjected to pre-processing techniques, such as reprojection of its coordinate reference system to UTM (24s time zone) and of its geodetic system to SIRGAS 2000, as well as exclusion of its spurious pixels. These procedures allowed the obtaining of accurate morphometric parameters. The results showed that morphometric characterization, through the processing of Digital Elevation Model (DEM) data in a Geographic Information System (GIS) environment, offers significant advantages in terms of cost-benefit. The methodology applied proved to be adequate and easy to use. The slope of the municipality is predominantly undulating to strongly undulating. The conception of the results achieved in this study allows a consistent understanding of the morphometric behavior of the municipality of São João do Sabugi - RN, which can be used for adequate environmental planning.Item Uso de armadilha atrativa na captura de Rhynchophorus palmarum (L) em plantio de dendê na Zona da Mata Norte de Pernambuco(2024-03-08) Santana, Alisson Gomes de; Gonçalves, Maria da Penha Moreira; http://lattes.cnpq.br/0539509819672370; http://lattes.cnpq.br/8309879042134974
