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 Morfologia das glândulas salivares de Bradypus variegatus (Schinz,1825)(2022-10-19) Silva, Lorena Nascimento da; Amorim, Marleyne José Afonso Accioly Lins; http://lattes.cnpq.br/1237734889563996; http://lattes.cnpq.br/2955989152624454Item Estudo anatômico do cerebelo de Bradypus variegatus, Schinz 1825 (Mammalia: Pilosa)(2022-05-24) Oliveira, Ueliton da Silva; Amorim, Marleyne José Afonso Accioly Lins; http://lattes.cnpq.br/1237734889563996; http://lattes.cnpq.br/9250603868698523The common sloth (Bradypus variegatus, Schinz 1825) is an arboreal quadruped species belonging to the Class Mammalia, Superorder Xenarthra and Family Bradypodidae. In South America, it inhabits from northern Colombia to southwestern Venezuela, southern Ecuador, eastern Peru and Bolivia, in addition to being present in Brazil. In the case of organic systems, bradypodids have certain anatomical peculiarities such as double posterior vena cava, six to nine cervical vertebrae depending on the species; common duct for the urinary and genital tracts in females and internal testes in males. However, there are few studies concerning the central nervous system, especially when comparing them to domestic animals. Therefore, the present work aims to analyze, describe and morphologically characterize the cerebellar structures of the Bradypus variegatus sloth. 10 animals were used for the analyses, obtained after natural death from the Wild Animal Screening Center, and fixed in 20% formaldehyde. Reserved in numbered tanks in 30% saline solution, the animals also received individual identifications. The skullcap and brain were removed to gain access to the cerebellum. The organ was separated from the brain stem by a cross section and preserved in a 20% formaldehyde solution in glass reservoirs. The cerebellar structure of common sloths, in both males and females, was, on average, 1.21 cm long by 1.62 cm wide. From the analysis carried out, it is concluded that the B. variegatus cerebellum has an ovoid morphology, slightly flattened in the cranial and caudal lateral portions, presenting the worm in the central region, right and left hemispheres with lobes and fissures, which corroborate with descriptive studies performed on humans and domestic animals.Item Estágio curricular supervisionado obrigatório: mapeamento do risco de inundação do município de São Lourenço da Mata – PE(2020-11-04) Freitas, Pedro Marcos Lira de; Caldas, Anildo Monteiro; http://lattes.cnpq.br/6543959400281255; http://lattes.cnpq.br/8259855042440433
