Item 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 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 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 speciesItem Anuros associados à fitotelma da Mata Atlântica no Nordeste do Brasil(2022-05-26) Barbosa, Géssica Gomes; Silva, Rafael Pereira da; http://lattes.cnpq.br/4809009611713171; http://lattes.cnpq.br/8932736287240209Item Dinâmica da ocupação de Dendropsophus decipiens (Lutz, 1925) em bromélias de um fragmento de Mata Atlântica semidecidual(2019-12-13) Santos, Rebeca Vitória Inácio dos; Araújo, Alan Pedro de; Moura, Geraldo Jorge Barbosa de; http://lattes.cnpq.br/1348666346504103; http://lattes.cnpq.br/7843892415680764; http://lattes.cnpq.br/7183058148320345By offer microhabitat, bromeliads are of great importance in the life of amphibians. Anuran bromeliads eventually use bromeliads, and in the rainy season they go to water bodies like temporary puddles and lakes to breed. It is not known if these adults return to the same bromelials or even if their descendants also return. Thus the following work aims to understand the dynamics of occupation of Dendropsophus decipiens (Lutz, 1925) living in bromeliads during a dry and rainy period in bromelials located in the Alto da Buchada Forest in the Tapacurá ecological reserve in the metropolitan region of Recife. The collections were performed from October 2017 to October 2018, with a sampling effort of four people where the method used was the visual active search, done at night between 18:00 and 22:00. The collected specimens were weighed, measured individually marked by the elastomer technique. The abundance of anurans was 127 individuals collected and through this study found that precipitation and temperature were important factors in the presence or absence of these animals in the bromelials.Item Variação inter e intraespecífica do canto de anúncio de Dendropsophus elegans (Wied- Neuwied, 1824) (Anura: Hylidae) em um fragmento de Mata Atlântica no Nordeste brasileiro(2019-12-13) Santana, Adsson Rodrigues de; Santos, José Ricardo de Oliveira; Moura, Geraldo Jorge Barbosa de; http://lattes.cnpq.br/1348666346504103; http://lattes.cnpq.br/5069434686181629; http://lattes.cnpq.br/7402092609251849
