Item Visitantes florais da jurubeba (Solanum paniculatum), no Setor de Meliponicultura, do Departamento de Zootecnia da UFRPE (Campus Dois Irmãos)(2025-02-24) Santos, Andreilson José dos; Souza, Darclet Teresinha Malerbo de; http://lattes.cnpq.br/3266223126925865A jurubeba (Solanum paniculatum) é uma planta medicinal indicada para o tratamento de diferentes tipos de doenças. Ela é um arbusto nativo das regiões Norte e Nordeste do Brasil, possui folhas de sabor amargo e frutos amarelo-esverdeados, que também podem ser incluídos na alimentação. O objetivo deste trabalho foi identificar os visitantes florais da jurubeba, tipo de coleta (pólen, néctar e/ou resina) e a frequência dessas visitações. O experimento foi realizado no Setor de Meliponicultura do Departamento de Zootecnia, na Universidade Federal Rural de Pernambuco, em Recife, PE. As observações foram realizadas das 6h às 16h, nos 10 minutos iniciais de cada horário, com três repetições, em três dias distintos, em janeiro de 2024. Foi observada a presença de várias espécies de abelhas, coletando pólen nas flores da jurubeba, entre elas: Augochloropsis sp. (53,7%), Bombus atratus (31,5%) e Melipona scutellaris (3,7%). Outros insetos como dípteros (11,1%) também foram observados nas flores. As abelhas Augochloropsis sp., da família Halictidae, aumentaram sua frequência até 11h, diminuindo após esse horário. As abelhas B. atratus visitaram as flores da jurubeba durante todo o dia, com pico de frequência entre 6h e 7h. As abelhas M. scutellaris visitaram as flores da jurubeba apenas entre 7h e 8h. Os dípteros foram observados apenas entre 9h e 12h. Concluiu-se que a jurubeba é uma planta que fornece pólen para diversas espécies de abelhas, sendo importante para a manutenção da biodiversidade dos polinizadores.Item A Área de Proteção Ambiental (APA) Aldeia-Beberibe como local de pesquisa acadêmica: uma análise da produção científica realizada entre 2000 e 2022(2024-10-04) Silva, Mariane Cássia da; Silva, Ana Carolina Borges Lins e; http://lattes.cnpq.br/7518216414237885; http://lattes.cnpq.br/1828286294878920The Atlantic Forest is a critical global biodiversity hotspot. In the Brazilian Northeast, the Aldeia-Beberibe Environmental Protection Area (APA) plays a key role in forest conservation and the protection of headwaters for some of the region’s important rivers. Analysing the scientific studies conducted in this area provides insights into its biodiversity and aids in planning conservation efforts. This research aimed to assess how the area is being used for biodiversity studies, which locations are being accessed, and to understand the fields of research being published. A bibliographic survey covering the period from 2000 to 2022 was conducted, with data collection extending from September 2023 to June 2024, to examine scientific trends, categorizing studies by research areas, locations, and the involvement of other protected areas within the territory. The analysis revealed a gradual increase in research since the creation of APA Aldeia-Beberibe in 2010. Botany, Zoology, and Ecology were the most frequently published fields, with research concentrated in the Mata da Usina São José Wildlife Reserve (RVS) and the Dois Irmãos State Park (PEDI). These results provide significant insights into the local biodiversity, indicating better guidance for managing the APA Aldeia-Beberibe, as well as information for a more effective conservation strategies for this natural heritage.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 Biodiversidade de tardígrados limnoterrestres da UFRPE - Campus Dois Irmãos (Sede)(2023-04-25) Silva, Agelson Santana da; Rocha, Clélia Márcia Cavalcanti da; Santos, Érika Cavalcante Leite dos; http://lattes.cnpq.br/1552807658058972; http://lattes.cnpq.br/8971495967943784; http://lattes.cnpq.br/0953438836794634Tardigrades, known as water bears, are cosmopolitan invertebrates, found in all biomes on Earth, from very cold places (Arctic and Antarctica) to hot springs. They are animals that are only active surrounded by water, and when they are deprived of it they enter cryptobiosis, their extraordinary survival technique. Despite this ability to survive in extreme environments through cryptobiosis leaving everyone awestruck and having boosted research on them a few decades ago, tardigrades are still little studied, which is attributed to their still unknown economic, medical or even ecological importance. In the present study, we seek to know the biodiversity of limnoterrestrial tardigrades on the main campus of UFRPE, in the neighborhood of Dois Irmãos in Recife (PE), in addition to enriching the scarce literature about these charming beings. With this, collections were made at 5 points on the university campus, in order to record the biodiversity of tardigrades found in the different substrates sampled. Samples of mosses, liverworts and lichens were stored in paper envelopes and subsequently sorted following methodologies found in the literature. After definitive preparation of the specimens found, identification was carried out using a binocular microscope (100X magnification by immersion) and taxonomic keys. Our results were quite rewarding, since we found two genera that had their first occurrence records for the state of Pernambuco (Bryodelphax sp. Thulin, 1928 and Murrayon sp. Bertolani & Pilato, 1988) and a genus with the first record for the country (Xerobiotus sp. Bertolani & Biserov, 1996), thus achieving our objective of contributing to the knowledge of the biodiversity of limnoterrestrials tardigrades from Pernambuco and Brazil, in addition to opening new perspectives regarding their study in the approached locality.Item Levantamento da fauna apícola em monocultivo de sabiá (Mimosa caesalpiniifolia) em área de Caatinga no Agreste pernambucano(2021) Silva, Isabela Nascimento; Gonçalves, Maria da Penha Moreira; http://lattes.cnpq.br/0539509819672370; http://lattes.cnpq.br/6582276513482324Due to the semi-arid climate characteristics, the Caatinga biodiversity presents a rich diversity of plant and animal life. Within this wealth, native bees stand out, which play an important role in the balance of forest ecosystems. Thus, the objective of the present work was to carry out a survey of the apicultural fauna in areas of sable cultivation and native vegetation of Caatinga in the rural region of Pernambuco. The research was carried out at the experimental station of the Instituto Agronomic° de Pernambuco - IPA, municipality of Caruaru, Pernambuco. The study was carried out during the months of December 2020 and January 2021 in two areas of Caatinga equidistant 30 m from each other, one planted with thrush (Mimosa caesalpiniifolia) and the other with native vegetation. In each area, two 10 m x 10 m transects were drawn for the installation of traps. Two models of traps were installed, one with a bottle using scent essences (vanilla and methyl salicylate) and another with yellow Pantraps, in which the attractiveness is based on color. 29 individuals of bees distributed in three genera were catalogued. Of these, two were identified at the genus level (Trigona sp., Bombus sp.) and one at the species level (Apis melifera scutellata). Pantraps did not attract any insect considered to be a bee, regardless of the area or period of collection. A higher frequency of bees was observed in the dry period compared to the rainy period. In the sabia area there was greater visitation by bees (82% of the individuals) and greater preference for visitation after using the methyl salicylate essence (79% of the individuals), however the vanilla essence was efficient in attracting them. It is concluded that the method of collecting bees using scent traps in the Caatinga environment of the Pernambuco agreste proved to be efficient when using vanilla and methyl salicylate essences, the latter being the most effective in attracting these insects. The modifications that occurred in the monoculture of Sabia in the Caatinga environment did not negatively influence the diversity of bees, when compared to the area of native forest in the region, with similar diversity being observed in both areas.Item Composição das assembleias de drosofilídeos (Insecta, Diptera) em um fragmento preservado de Floresta Atlântica comparado com um ambiente degradado nas suas imediações(2021-08-06) Santos, Vinícius Alcântara Carvalho Lima; Montes, Martín Alejandro; Garcia, Ana Cristina Lauer; http://lattes.cnpq.br/0563243377799793; http://lattes.cnpq.br/0349635170206363; http://lattes.cnpq.br/7512572540450427Invasive species are among the biggest causes of biodiversity loss on the planet. Biological invasions continue to grow throughout the world, including in the Drosophilidae family. The present study aimed to observe the diversity of Drosophilidae assemblages from a protected area, the Dois Irmãos State Park and an outside area near it, the Universidade Federal Rural de Pernambuco (Federal Rural University of Pernambuco) and their sazonal patterns. There were four collecting expeditions in each area, two in the dry season, two in the rainy season, using five banana bait traps to attract the drosophilids. A total of 25,108 drosophilids of 4 genera and 21 taxa were collected. The sites presented a composition of similar richness and abundance, with a great predominance of exotic species, which represented 91.4% of the total, and only one species, Drosophila malerkotliana, was the most abundant and represented 70.4% of the abundance alone. It was noticed that this species also dominated the composition of the protected area, that was not the case in a previous study in the same place, in which native species of the willistoni subgroup dominated the assemblage. It is still too early to say what may have caused the results shown here, and further studies are necessary to observe whether the trend of the dominance of the assemble by exotic species will stay in future samplings.Item Composição da nematofauna em uma praia urbana tropical impactada por efluentes de esgoto(2022-10-07) Bezerra, Pâmela da Silva; Guilherme, Betânia Cristina; Silva Filho, Mário Guimarães da; http://lattes.cnpq.br/0770757545098826; http://lattes.cnpq.br/3131730022364100; http://lattes.cnpq.br/7169142852187773Sandy beaches have complex hydrodynamic processes and they are widely used for tourism and recreation. The interstitial space provides habitat for organisms of the Phylum Nematoda, considered the most abundant in unconsolidated bottom benthic ecosystems. The distribution tends to suffer interference, mainly, from granulometry, in addition to other factors. The present study investigated the nematofauna composition on a tropical urban beach impacted by sewage effluents, to test two hypotheses: 1) the structure of the nematofauna community is influenced by granulometric characteristics and 2) the nematofauna composition on the beach of Barra de Jangada presents temporal differences, considering the trophic groups and maturation stages. The collections were carried out in the months of July (rainy season) and September (dry season) of 2020. In each one, two transects were established, one of them located close to a sewage along the intertidal zone and the other distant at 100 meters. In each transect, four sampling points were marked, then biosedimentological replicas and for granulometric analysis were collected. Samples were screened and nematodes identified at the genus level. The sediment was predominantly classified as moderately well sorted fine sand. We recorded 42 genera, belonging to 20 families, Xyalidae being the most representative, with greater abundance and richness of genera. The genera Promonhystera, Theristus, Mesacanthion, Paracanthonchus and Pseudosteineria represented more than 90% of the samples. The greatest richness found occurred in the dry season and, considering the transects, the first one showed greater diversity. The upper midlittoral region had the lowest diversity between the zones in both months. PERMANOVA indicated significant differences in communities and DistLM showed that granulometry significantly influences community composition. The most abundant trophic group was non-selective deposit eaters. Juveniles were dominant in the both periods.Item Relação das espécies de abelhas nativas no Setor de Meliponicultura do Departamento de Zootecnia, da UFRPE (Campus Dois Irmãos)(2022-06-01) Silva, Robin César Barros da; Souza, Darclet Teresinha Malerbo de; http://lattes.cnpq.br/3266223126925865; http://lattes.cnpq.br/0227744215116433Bees have a role in nature of fundamental importance in the balance of an ecosystem, being directly responsible for the pollination of plants, certain types of food that are only viable due to this arduous task, bees are present around the world and have thousands of different species, including those with stingers and those without stingers. Meliponiculture, which is the production of native stingless bees, has been increasingly developed with the growing search for natural and sustainable products, created in a rational way, and this is something that has been developed for many generations by indigenous peoples. The meliponiculture sector, located in the Zootechnics Department at UFRPE in Recife, comes through the efforts of its teaching, research and extension activities, to emphasize and propagate the importance of preserving these insects so important for the functioning of the production chain and consequently of life human. The different species that are found in the sector are native to the region of the Zona da Mata and coast of Pernambuco, where the department is close. The sector seeks to preserve these colonies for the dissemination of knowledge with society. The species found in the structure of the meliponary were cataloged and the development of these colonies was monitored, as well as artificial feeding was offered to those colonies that had a deficit of food stored in their boxes.Item Biodiversidade e comportamento forrageiro das abelhas nas inflorescências do coentro (Coriandrum sativum L.)(2021-06-30) Santana Filho, Paulo Amaro de; Souza, Darclet Teresinha Malerbo de; http://lattes.cnpq.br/3266223126925865The study of plants supplying trophic resources to bees is important for the preservation, management and production of beekeeping and meliponiculture. The objective of this research was to study the biodiversity and forage behavior of bees in coriander inflorescences. This experiment was conducted at the Federal Rural University of Pernambuco, Campus Dois Irmãos, located in Recife, PE. The frequency of visitations and the type (nectar and / or pollen) of bees collected in the coriander inflorescences during the day were evaluated. These data were obtained by counting in the first 10 minutes of each time, between 9:00 a.m. and 5:00 p.m. with three repetitions, during three distinct days. Mainly bees were observed visiting coriander inflorescences being stingless bees Trigona spinipes (35,95%), stingless bees Plebeia sp. (12.21%), Africanized honeybees Apis mellifera (5,78%), Halictidae native bees (3,1%) and stingless bees Frisiomellita varia (0.99%). T. spinipes stingless bees were the most frequent and constant, collecting nectar and pollen. This plant species should be planted near apiaries and meliponaries being an important source of food resources for both Africanized and wild bees in Recife, PE.
