Item Análise faunística de dípteros de interesse forense associados à carcaça de coelho (Oryctolagus cuniculus Linnaeus, 1758) em fragmento de Mata Atlântica, Dois Irmãos, Recife/Pernambuco(2025-03-21) Silva, Vanessa Ferreira da; Santos, Arlene Rodrigues Bezerra dos; http://lattes.cnpq.br/3921810982238132; http://lattes.cnpq.br/3326176614318841Os insetos, que representam 70% das espécies do Reino Animalia, são altamente adaptáveis e desempenham funções ecológicas essenciais. A ordem Diptera, especialmente relevante na decomposição cadavérica, tem grande importância ecológica e forense. Estudos faunísticos são cruciais para entender a entomofauna local, auxiliar na identificação de insetos em carcaças e contribuir para investigações forenses. Este trabalho objetivou realizar uma análise faunística de dípteros de interesse forense associados à carcaça de Oryctolagus cuniculus Linnaeus, 1758, em um fragmento de Mata Atlântica, localizado em Dois Irmãos, Recife/Pernambuco. Os dípteros foram coletados entre 12 e 20 de fevereiro de 2025, capturados na carcaça e arredores, e enviados ao Laboratório de Entomologia Forense (LEF) para triagem e identificação. Larvas foram acondicionadas em potes com serragem e dieta específica para acompanhamento do desenvolvimento. A identificação taxonômica foi feita com estereoscópio binocular e chaves dicotômicas, e os dados foram analisados com atributos ecológicos e testes estatísticos. Ao final das coletas, foram capturados 201 dípteros adultos, pertencentes a nove famílias, sete gêneros e 30 espécies. As famílias registradas foram Fanniidae (32,8%), Sarcophagidae (27,9%), Calliphoridae (18,4%), Ulidiidae (7,5%), Muscidae (5,5%), Sepsidae (3,5%), Phoridae (2,5%), Richardiidae (1,5%) e Drosophilidae (0,5%). Além disso, foram coletadas 174 larvas, das quais 163 atingiram a fase adulta, distribuídas entre as famílias Sarcophagidae (48,5%), Calliphoridae (28,2%) e Fanniidae (23,3%). As espécies Fannia pusio (Wiedemann,1830), Oxysarcodexia fringidea (Curran, Walley,1934) e Fannia canicularis (Linnaeus, 1761) foram predominantes no estudo. As coletas mostraram variações na ocorrência das espécies ao longo dos diferentes estágios de putrefação. O período gasoso apresentou maior abundância e maior índice de diversidade de Shannon. Enquanto o período cromático uma menor abundância e um menor índice de diversidade de Shannon. A correlação de Pearson para avaliar a relação entre temperatura e abundância das famílias coletadas indicou que a temperatura não influenciou diretamente a variação na abundância dos indivíduos. Portanto, a pesquisa contribui na formação de um banco de dados regional crucial para a entomologia forense em Pernambuco.Item Diversidade de besouros escarabeíneos (Coleoptera: Scarabaeidae: Scarabaeinae) da Universidade Federal Rural de Pernambuco UFRPE/Sede(2024-10-04) Assis Júnior, José Fernando de; Liberal, Carolina Nunes; http://lattes.cnpq.br/7390869942259612; http://lattes.cnpq.br/8327288458916924Scarab beetles are called "dung beetles", this name was given due to the peculiar behavior of some individuals, these beetles modulate and roll some balls made with the feces of other animals. In Brazil, 786 species included in 69 genera are recorded, and in the state of Pernambuco, 16 species distributed in 8 genera are found. The consequences of the behavior and life cycle of these individuals include several environmental services, such as increased nutrient cycling rate in the environment, soil fertilization and aeration, reduced transmission of some vertebrate parasites by killing larvae and eggs, secondary seed dispersal and contribution of biomass to higher trophic levels. However, environmental disturbances can drastically alter the structure of the community, decrease diversity and lead to the loss of ecosystem functions of scarab beetles. The present study aimed to understand the diversity of scarab beetles at the Federal Rural University of Pernambuco. With approximately 147 hectares of extension, the UFRPE Main Campus has areas composed of vegetation from the Atlantic Forest biome. Three collections were carried out in each season, two collections in August and October 2023, in addition to four collections in the months of January, March, April and May 2024, totaling six collections. To capture scarab beetles, 10 points were delimited at the Federal Rural University of Pernambuco, with a minimum distance between points of 100 m. The area was mapped using the AlpineQuest program and at each of the points a set of two pitfall traps was installed, 3 m apart from each other, totaling 20 traps in the study area. Due to the fall of trees and opening of the canopy, the vegetation structure was modified, making it necessary to change some points for collection during the rainy months. For the ecological analysis, we used the Rényi Diversity Profile, the Shapiro-Wilk test, the Levene test and the Tukey test to complement the results of the Analysis of Variance. Analyzing the baits and seasons, we observed that species diversity was higher in the feces pitfalls and in the rainy season. The analysis of variance for species abundance showed that there was an interaction between the bait and season factors, in other words, the impact of one factor depends on the level of another factor, which was not observed in the analysis of variance for species richness.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 Influência do cocultivo de bactérias promotoras de crescimento no desenvolvimento morfofisiológico de Canistrum aurantiacum (Bromeliaceae)(2024-03-07) Ferreira, Esdras de Souza; Silva, Cláudia Ulisses de Carvalho; Oliveira, Henarmmany Cristina Alves de; http://lattes.cnpq.br/6859724202937192; http://lattes.cnpq.br/7161911278790052; http://lattes.cnpq.br/0201835717024585The reintroduction of vulnerable species is a common practice in ecological conservation and restoration, aiming to address the challenges arising from habitat fragmentation and climate change. However, reintroduction attempts of native plants, such as Canistrum aurantiacum, often encounter difficulties in establishing lasting reproductive populations. A promising approach to improve the success of these reintroductions is co-cultivation with growth-promoting bacteria (GPBs), which can benefit plant development at various stages of cultivation. This study sought to evaluate the impact of GPB co-cultivation on the growth and development of C. aurantiacum seedlings. The experiment was conducted in a greenhouse attached to the Plant Physiology Laboratory (LFP) at the Federal Rural University of Pernambuco (UFRPE), Recife-PE. Seeds of C. aurantiacum were sown in trays containing organic substrate and washed sand. After 90 days, the plants were transplanted into containers containing a mixture of organic substrate and sand, previously sterilized. Five GPB treatments, including a control, with 10 replicates each, were used. The plants were inoculated with bacterial suspension or sterile deionized water and maintained under these conditions for 64 days. Biometric and total chlorophyll content analyses were conducted throughout the experiment. The data obtained were analysed using ANOVA, and the means were compared employing the Tukey test at a 5% significance level. However, no significant differences were observed between the treatments regarding these variables. The results indicate that GPB inoculation had no significant effect on the growth and chlorophyll content of C. aurantiacum during the study period. This finding suggests that other factors, such as interspecific interactions between plants and microorganisms, may have influenced plant development. Therefore, further research is needed to better understand the effectiveness of GPB co-cultivation as a management strategy for vulnerable species in reintroduction programs.Item Prospecção de pigmentos de fungos isolados de solo de área preservada(2024-02-20) Souza, Ana Beatriz de Andrade; Siqueira, Virgínia Medeiros de; http://lattes.cnpq.br/5524459744893735; http://lattes.cnpq.br/2810164333813638In recent years, several studies have highlighted the harmful effects of artificial substances used in the food, agriculture, and pharmaceutical industries, especially synthetic dyes. As an alternative to these substances, the search for fungi producing pigments has emerged as a promising option. Specifically, filamentous fungi have the ability to produce secondary metabolites that can replace synthetic products or serve as raw material for new products, minimizing this problem. In this context, the present study aimed to evaluate the pigment production capacity of filamentous fungi isolated from soil in a preserved area at the Curado Forest Wildlife Refuge (RVS), Recife-PE. After isolation and quantification procedures, five isolates capable of producing extracellular pigments in solid culture medium were selected, identified as Paecilomyces (isolates 01 and 11), Penicillium (isolate 07), Phoma (isolate 16), and Aspergillus (isolate 18). Subsequently, these fungi were cultured in liquid culture media and subjected to different pH, nutrient, and temperature conditions, with agitation at 150 rpm for 9 days. As a result, the conditions in which all isolates maintained pigment production were in Potato Dextrose Broth and Czpeck Broth, pHs 4.5 and 7.0, and temperature of 25°C, indicating that 15°C was a limiting factor when compared to all isolates tested. Additionally, the extract containing the pigments was tested for its antimicrobial capacity, but none of them showed activity against Candida albicans, Escherichia coli, and Staphylococcus aureus. Thus, it is concluded that soils from preserved areas are sources of fungi capable of producing extracellular pigments, which can be further studied in future research for their various applications. Finally, the results presented here emphasize the importance of maintaining preserved areas, valuing the fungal component present in soils, and that besides their ecological role, it is possible to add biotechnological value to them.
