Resumo: The study of small mammals in owl pellets, especially of the genus Tyto, is considered a useful and complementary tool in mammalogy. However, few studies using this kind of information have been conducted in southern Brazil. We analyzed craniodental remains of small mammals in Tyto furcata pellets from seven locations in the three southern Brazilian states. In all, 2,382 individuals belonging to 29 taxa were recorded, including 5 marsupials (Didelphidae; 1.39% of individuals), 4 chiropterans (Molossidae, Phyllostomidae and Vespertilionidae; 0.25%), and 20 rodents (Cricetidae, Muridae, Caviidae and Echimyidae; 98.36%). The rodents Akodon spp., Oligoryzomys sp. and Mus musculus were the most common taxa. The sample also included taxa with few recorded localities previously published, such as the rodents Bibimys sp., Calomys tener and Wilfredomys oenax. The richness of small mammals obtained in the samples studied corroborates the utility and importance of analyzing pellets of birds of prey. In addition, our contribution highlights the need for more detailed studies on the morphology and identification of several mammalian species, such as those of the genera Akodon and Oligoryzomys, considering the fragmentary nature of the specimens retrieved from pellets.

No entanto, poucos estudos deste tipo têm sido desenvolvidos no sul do Brasil. Foram analisados os fragmentos cranianos e mandibulares de pequenos mamíferos encontrados em egagropilos de Tyto furcata coletados em sete localidades dos três estados do sul do país. Ao todo, foram contabilizados 2.382 indivíduos pertencentes a 29 táxons, incluindo cinco marsupiais (Didelphidae; 1,39% dos indivíduos), quatro quirópteros (Molossidae, Phyllostomidae e Vespertilionidae; 0,25%) e 20 roedores (Cricetidae, Muridae, Caviidae e Echimyidae; 98,36%). Os roedores Akodon spp., Oligoryzomys sp. e Mus musculus foram os táxons mais comuns. A amostra inclui espécies com poucos registros para o sul do Brasil, como Bibimys sp., Calomys tener e Wilfredomys oenax. A riqueza de pequenos mamíferos obtida nessas amostras corrobora a utilidade e importância da análise de egagropilos de aves de rapina. Ainda assim, são necessários estudos mais detalhados sobre a morfologia e identificação das espécies, como de Akodon e Oligoryzomys, considerando-se a natureza fragmentária do material nos egagropilos.Universidade Federal de Santa Catarina2018-09-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2018v31n3p4310.5007/2175-7925.2018v31n3p43Biotemas; v. 31 n. 3 (2018); 43-582175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2018v31n3p43/37497Copyright (c) 2018 Jorge José Cherem, Patrícia Hadler, Narla Shannay Stutz, Ulyses Francisco José Pardiñasinfo:eu-repo/semantics/openAccessCherem, Jorge JoséHadler, PatríciaStutz, Narla ShannayPardiñas, Ulyses Francisco José2019-03-01T16:15:58Zoai:periodicos.ufsc.br:article/56579Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2019-03-01T16:15:58Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
