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 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 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.
