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 Análise da regeneração natural em áreas de restauração florestal na Zona da Mata Sul de Pernambuco(2023-09-14) Calixto, Shermesson Henrique Mota; Feliciano, Ana Lícia Patriota; Silva, Marília Isabelle Oliveira da; http://lattes.cnpq.br/1029149032423660; http://lattes.cnpq.br/9184673853412326; http://lattes.cnpq.br/3349917891877024In the evaluation of the restoration process, natural regeneration is a relevant indicator for evaluate the functioning of recovering ecosystems. This is because it represents the processes of species establishment and the sustainability of the tree community, which is responsible for triggering ecological processes. This study aimed to analyze natural regeneration in two riparian areas located in the South Wood Zone of Pernambuco, with the intention of inferring about the forest restoration process of these environments. The work was carried out in two areas undergoing restoration (Palma III and Palma IV), located in Sirinhaém/PE. Twenty plots (5 x 5 m) were installed in each study area, and floristic and phytosociological surveys were conducted to verify composition and structure. Regenerating individuals were considered those with a height equal to or greater than 1 m and with a circumference at breast height (CBH) less than 15 cm. After species identification, their origin, endemism, ecological groups, dispersal syndromes, and pollination syndromes were determined. The main results of the floristic analysis showed that the majority of species in the Palma III area (PIII) are early successional species, while pioneers occupy that space in the Palma IV area (PIV). In both areas, most species have zoochorous dispersal syndrome and melittophilous pollination syndrome, and they are native to the Atlantic Forest biome and not endemic. In the PIII area, the species Guarea guidonia was dominant, representing 70.80% of the total density of the study and occupying 85% of the plots with a total of 80 individuals. These factors resulted in low diversity and evenness indices in the area. Guarea guidonia was also the dominant species in the PIV area, but with a more balanced proportion of individuals, with 21 individuals representing a total density of 31.34%, present in 50% of the plots. PIV alsoItem Diversidade funcional da comunidade de besouros escarabeíneos (Coleoptera: Scarabaeidae: Scarabaeinae) na Estação Ecológica do Tapacurá, Pernambuco, Brasil(2024-03-08) Silva, Bruno Bispo da; Liberal, Carolina Nunes; http://lattes.cnpq.br/7390869942259612; http://lattes.cnpq.br/1411320038538078The attractiveness of scarabeine beetles (Coleoptera: Scarabaeidae: Scarabaeinae) for different types of resources means that they can be divided into guilds related to behavior (resource allocation, diet and period of activity) and morphological variations (size, shape and biomass ). Different combinations of these characteristics confer different competitive capabilities between species, which can reduce direct competition and allow the coexistence of different species. The impoverishment of dung beetle communities implies a disruption in the important ecological services they offer. Thus, the present study aimed to analyze the functional diversity of the dung beetle community at the Estação Ecológica do Tapacurá, PE. Specifically, identify the functional groups present in the community according to functional traits: biomass, food preference and resource allocation. For this, two collections were carried out in 2023, one in February (dry season) and another in March (rainy season), at ten points, distributed to form a transect, with a minimum distance between points of 100m. At each point, a set of two pitfall traps were installed, baited with human feces and rotted bovine spleen and exposed for 48 hours/collection. A total of 940 beetles were collected, 763 from meat baits (352 in the dry season and 411 in the rainy season) and 177 in the feces baits (90 in the dry season and 87 in the rainy season). 19 species were identified, belonging to eight genera: Anomiopus, Ateuchus, Canthidium, Canthon, Coprophanaeus, Deltochilum, Dichotomius and Eurysternus. Beetles were classified into functional groups based on size according to biomass (large and small), resource allocation and food preference. The study showed that the community is mainly composed of small beetles, paracoprids or telecoprids, generalists or scavengers, while endocoprids and coprophages were represented by a single species each. The lower number of beetles in the feces bait suggests a low abundance of mammals in the region, its main source of resources. Highlighting the functional diversity present among dung beetles in the region and the importance of continuing to monitor these communities to understand their role in ecosystems.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.Item Influência do monocultivo de pau-brasil (Paubrasilia echinata Lam E. Gagnon, H. C. Lima & G. P. Lewis, Fabaceae) na regeneração e fauna edáfica em área de Mata Atlântica de Pernambuco(2023-09-21) Nogueira, Natália Dias Guerra; Gonçalves, Maria da Penha Moreira; Lima, Tarcísio Viana de; http://lattes.cnpq.br/0814281560377954; http://lattes.cnpq.br/0539509819672370; http://lattes.cnpq.br/1735222852823675Restoration processes of tropical forests can be conducted through the planting of native species in degraded areas caused by human activities, aiming for the gradual reconstruction of a dynamic and biodiverse ecosystem. However, little is known about the performance of a native species planted in a monocultural model for restoration purposes. Based on this principle, the objective of this research was to assess the influence of the monocultural system with Paubrasilia echinata on the regeneration flora and soil fauna in the understory of a Semideciduous Seasonal Forest environment in Pernambuco. For this purpose, two areas were selected: one in passive restoration with a plantation of Pau-Brasil aged over 50 years (BPB), and an adjacent Native Forest (MN) area used as a control area, both within a protected area of the Tapacurá Ecological Station, an advanced campus of UFRPE. A survey of natural regeneration and soil fauna was conducted as ecological indicators in both areas, with a total of 6 plots measuring 600m² each. For regeneration, tree individuals with a Circumference at Breast Height (CBH) of up to 15cm and a minimum height of 1m were measured, identified to the species level, and classified by origin, dispersal syndrome, and ecological groups. Richness was determined by the species list, and diversity was assessed using Shannon-Weaver Diversity Indices, Simpson's Dominance, and Pielou's Evenness. The species were analyzed both horizontally and in 3 height classes. To evaluate the soil fauna, pitfall traps were used, 9 in each area, the collected organisms were screened and identified, when possible, at order level. The analysis of the edaphic fauna was made through the ANAFAU program, which provides ecological indexes and information on the structure of the community. The results of the ecological indexes of the two indicators were compared by the Hutcheson t test in the PAST program. As a result, in natural regeneration the area of MN presented greater richness and higher values of diversity and equability, while the area of BPB presented higher dominance due to the superior and expressive presence of individuals in regeneration of the species. There was a significant statistical difference for the diversity and dominance of natural regeneration among the studied areas. In both areas it was observed a greater number of zoochoric species and highlight to the ecological group of early secondary. Only in the area of MN there were records of exotic species. Individuals were observed in the three height classes in both areas, being the MN with the highest number of species with this representation. Regarding the edaphic fauna, higher values of abundance in the BPB area and greater richness in the MN area were verified, and the soil fauna diversity was similar between the areas. The orders Collembola, Hymenoptera and Diptera were highlighted for the two areas. The order Orthoptera was found in greater abundance and frequency in the BPB area. Therefore, the monoculture of Brazilwood has been negatively influencing the stratum of natural regeneration in questions of plant diversity and has been affecting the proportion of some groups of soil fauna.Item Micobiota oral de anuros encontrados em ambiente urbano e em borda de fragmentos de Mata Atlântica em Pernambuco(2023-04-27) Barreto, Lucas Barbosa; Lima, Marcos Antônio Barbosa de; Ferreira, Gêneses Silva; http://lattes.cnpq.br/6873402584180381; http://lattes.cnpq.br/3887006042216258; http://lattes.cnpq.br/1433421348080492Anurans of the Hylidae family are adapted to live in environments on the edge of the Atlantic Forest. Such individuals may be capable of dispersing potentially harmful fungi to humans. This study sought to investigate the oral microbiota of Hylidae in urban environments close to the Atlantic Forest and on the edges of these same fragments. Eleven individuals were collected, eight of which were in environments on the edge of the Atlantic Forest and three in an urban area. From this collection, 26 isolated filamentous fungi were recorded, with five identified genera (Aspergillus, Curvularia, Acremonium, Penicillium and Fusarium) and three isolates classified as Mycelia sterilia. Among these genera, the most abundant was Aspergillus with fourteen isolates. The environment with the greatest richness was on the edge of the Atlantic Forest. Thus, it is evident that the individuals of the Hylidae family, which were approached in the current work, present different genera of opportunistic fungi, which may be pathogenic. Therefore, further studies are needed for a better understanding of the potential dispersal role of fungi that individuals of the Hylidae family can play in humans.Item Diversidade e período de atividade de besouros escarabeíneos (Coleoptera: Scarabaeidae: Scarabaeinae) da Estação Ecológica do Tapacurá(2023-09-15) Cavalcanti, Juliana Ferreira; Liberal, Carolina Nunes; http://lattes.cnpq.br/7390869942259612; http://lattes.cnpq.br/3551522195847302Scarab beetles are detritivorous insects popularly known as “dung beetles”. They have a varied feeding habit, in general they can feed on feces (coprophages), decaying meat (necrophages) or decaying fruits (saprophages), or even on more than one type (generalist). Besides that, they play a very important role as bioindicators, as they are highly sensitive to environmental changes, undergoing changes in the structure of their community. Deforestation and fragmentation of forest environments are some of the most damaging disturbances to biodiversity by which scarab beetles are heavily affected. The Atlantic Forest is one of the Brazilian biomes in the most critical state of degradation, listed as one of the 36 biodiversity hotspots. The objective of this work was to know the diversity and period of activity of scarab beetles in the Atlantic Forest fragment of Tapacurá Ecological Station (8° 02′ 27.8″S and 35° 11′ 46.3″W), located in the municipality of São Lourenço da Mata, Pernambuco. Two samples were carried between the months of february and march, and march and april, where ten points were determined, distributed in order to form a transect. At each point, a set of two pitfall traps was installed, totaling 20 traps per area. Pitfalls were baited with fresh human feces and rotten bovine spleen. A total of 940 individuals distributed in five tribes, seven genera and 18 species of Scarabaeinae were captured. The most abundant species were Canthon terciae (34.47%), Deltochilum kolbei (23.40%) and Dichotomius guaribensis (14.47%). Of the 18 species collected, only 12 occurred in sufficient numbers to be classified in trophic guilds. Among these, seven were considered necrophagous , five generalists, and none were coprophagous. As for the period of activity, four species showed diurnal activity, four showed nocturnal activity, and another four species were considered of continuous activity. Rényi’s diversity profiles showed that the carrion bait had a greater diversity of species taking into account the most abundant species, and the feces bait was more diverse considering the rarest species.Item Invasão biológica por Epipremnum aureum (L.) Engl. e impactos sobre a regeneração natural em fragmento florestal urbano(2019-07-10) Tavares, Rita de Cássia da Silva; Silva, Ana Carolina Borges Lins e; Nascimento, Ladivânia Medeiros do; http://lattes.cnpq.br/0483385037934634; http://lattes.cnpq.br/7518216414237885; http://lattes.cnpq.br/5988869092122649Biological invasion is the process that involves the establishment and large proliferation of a species not native to the environment, leading to imbalances in the native community. Invasive alien species threaten ecosystems, habitats or species, due to their competitive advantages and facilitated by the absence of predators and the degradation of natural environments, caused mainly by anthropic actions. The biological invasions affect ecological processes and the physical environment, being one of the aggravating factors the influence on the successional processes of regeneration of the forests. Conservation Units are an active way of protecting biodiversity and natural resources. The invasive species Epipremnum aureum (L.) Engl. is possibly from the Solomon Islands and the main feature that distinguishes E. aureum from native species of the family Araceae is the membranous leaf blade, greenish discolor with yellowish macules. Its leaves when new are small, this size relative to the creeping terrestrial habit, but when adults begin to adhere in a stem gradually becoming larger. E. aureaum has a great capacity of colonization, allied to the favorable conditions of its propagation in the urban forest fragment of the JBR and from this problematic, the present study aims to check the impacts caused by this invasive species on the regeneration of this fragment, thus giving subsidy for future analyzes and prevention and control measures. Three ANI, AI1 and AI2 areas were sampled, classified in non-infested area and areas with infestation levels (predominance of invasive species), for analysis of floristic and structural described. After diagnosis, the density values showed a tendency to increase; difference in the distribution of abundance of individuals and decreasing diversity patterns throughout the infestation. There may be indications that these infested areas of the JBR fragment may be providing resources that benefit exotic species rather than native species
