Resumo: | The study of the feeding habits of carnivores is essential to understand the dynamics of the ecosystems in which they are inserted, since carnivores play a fundamental role in controlling prey and, for those whose diet is omnivorous, they can also act as seed dispersers. The present study aimed to evaluate the feeding habits of individuals of pampas fox (Lycalopex cf. gymnocercus) in the hybridization zone of the species, in an agricultural area in the interior of São Paulo, being the first study with this species. in the state, since, until recently, the species was restricted to southern Brazil. Through analysis of feces collected during a year, both from adults and young, it was possible to describe the diet of individuals residing in the area of Fazenda do Zoológico de São Paulo. Adults had a more varied diet than the young, consuming 28 taxa among vertebrates, invertebrates and plant material, in addition to different anthropic materials, such as aluminum foil, rubber and textile fabric. In general, invertebrates are consumed most frequently, followed by vertebrates and plant matter. However, consumption frequencies vary over the seasons, probably according to the availability of items. The offspring consumed 13 taxa, including vertebrates, invertebrates and plant matter (in addition to anthropic material - aluminum foil), with vertebrates being the most consumed items, which is expected, since they need higher levels of protein for their development. Despite the generalist diet, the niche breadth (calculated by the Simpson index) was low, both for adults and for pups. It is possible that opportunistic habits of individuals have generated this data, since, despite consuming a wide variety of taxa, most are consumed at low frequencies, while few are consumed at high frequencies. The studied individuals seem to tolerate modified environments, being able to consume urban garbage, domestic fruits and exotic species. However, the consumption of anthropic materials brings an alert about the risks of these environments and the proximity to humans, factors that need to be better studied. Finally, it is expected that the data obtained here can help in future management and conservation strategies, since the species is not native to the state and possible impacts on native fauna and flora are still unknown. |

O presente estudo buscou avaliar os hábitos alimentares de indivíduos de graxaim-do-campo (Lycalopex cf. gymnocercus) na zona de hibridação da espécie, em uma área agrícola no interior de São Paulo, sendo o primeiro estudo com esta espécie no estado, uma vez que, até recentemente, a espécie era restrita ao sul do Brasil. Através de análises de fezes coletadas durante um ano, tanto de adultos quanto de filhotes, foi possível descrever a dieta dos indivíduos que residem na área da Fazenda do Zoológico de São Paulo. Adultos apresentaram uma dieta mais variada que os filhotes, consumindo 28 táxons entre vertebrados, invertebrados e material vegetal, além de diferentes materiais antrópicos, como papel alumínio, borracha e tecido têxtil. De forma geral, invertebrados são consumidos em maior frequência, seguido de vertebrados e matéria vegetal. Porém, as frequências de consumo variam ao longo das estações, provavelmente de acordo com a disponibilidade dos itens. Os filhotes consumiram 13 táxons, entre vertebrados, invertebrados e matéria vegetal (além de material antrópico - papel alumínio), sendo que vertebrados foram os itens mais consumidos, o que é esperado, uma vez que precisam de níveis de proteína maiores para seu desenvolvimento. Apesar da dieta generalista, a amplitude de nicho (calculada pelo índice de Simpson) foi baixa, tanto para adultos quanto para filhotes. É possível que hábitos oportunistas dos indivíduos tenham gerado este dado, uma vez que, apesar de consumirem uma grande variedade de táxons, a maioria é consumida em baixas frequências, enquanto poucos são consumidos em alta frequência. Os indivíduos estudados parecem tolerar ambientes modificados, sendo capazes de consumir lixo urbano, frutas domésticas e espécies exóticas. Porém, o consumo de materiais antrópicos traz um alerta sobre os riscos destes ambientes e da proximidade com humanos, fatores que precisam ser melhor estudados. Por fim, espera-se que os dados aqui obtidos possam auxiliar em futuras estratégias de manejo e conservação, uma vez que a espécie não é nativa do estado e possíveis impactos na fauna e flora nativa ainda são desconhecidos.OutraporUniversidade Federal de São CarlosCâmpus São CarlosPrograma de Pós-Graduação em Conservação da Fauna - PPGCFauUFSCarAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessHábitos alimentaresEcologiaNicho tróficoCIENCIAS BIOLOGICAS::ECOLOGIADieta de Lycalopex cf. gymnocercus (Carnivora: Canidae) na zona de hibridação da espécieDiet of Lycalopex cf. gymnocercus (Carnivora: Canidae) in the hybridization zone of the speciesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesis6006006d131edf-18b3-465b-8a52-8607e22e88d6reponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINALDissertação Giannina_PPGCFau_FINAL.pdfDissertação Giannina_PPGCFau_FINAL.pdfapplication/pdf1397163https://repositorio.ufscar.br/bitstream/ufscar/16719/1/Disserta%c3%a7%c3%a3o%20Giannina_PPGCFau_FINAL.pdf8f738a2b1c8bfefb5571f5899214a170MD51Formulário_11_Normas para entrega da versao definitiva dissertacao e ou Tese_Autodeposito assinado.pdfFormulário_11_Normas para entrega da versao definitiva dissertacao e ou Tese_Autodeposito assinado.pdfapplication/pdf175764https://repositorio.ufscar.br/bitstream/ufscar/16719/3/Formul%c3%a1rio_11_Normas%20para%20entrega%20da%20versao%20definitiva%20dissertacao%20e%20ou%20Tese_Autodeposito%20assinado.pdf0e0e0b944e76d7be2b95c022720fc2a8MD53CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8811https://repositorio.ufscar.br/bitstream/ufscar/16719/4/license_rdfe39d27027a6cc9cb039ad269a5db8e34MD54TEXTDissertação Giannina_PPGCFau_FINAL.pdf.txtDissertação Giannina_PPGCFau_FINAL.pdf.txtExtracted texttext/plain131562https://repositorio.ufscar.br/bitstream/ufscar/16719/5/Disserta%c3%a7%c3%a3o%20Giannina_PPGCFau_FINAL.pdf.txt65d4f8b89d5f436c998d436b12edadfcMD55Formulário_11_Normas para entrega da versao definitiva dissertacao e ou Tese_Autodeposito assinado.pdf.txtFormulário_11_Normas para entrega da versao definitiva dissertacao e ou Tese_Autodeposito assinado.pdf.txtExtracted texttext/plain1364https://repositorio.ufscar.br/bitstream/ufscar/16719/7/Formul%c3%a1rio_11_Normas%20para%20entrega%20da%20versao%20definitiva%20dissertacao%20e%20ou%20Tese_Autodeposito%20assinado.pdf.txtad9b0805c9eb1d4b62b726ce41d7ce44MD57THUMBNAILDissertação Giannina_PPGCFau_FINAL.pdf.jpgDissertação Giannina_PPGCFau_FINAL.pdf.jpgIM Thumbnailimage/jpeg7927https://repositorio.ufscar.br/bitstream/ufscar/16719/6/Disserta%c3%a7%c3%a3o%20Giannina_PPGCFau_FINAL.pdf.jpgdde1a8ff6fb4b780abc9fffff494d852MD56Formulário_11_Normas para entrega da versao definitiva dissertacao e ou Tese_Autodeposito assinado.pdf.jpgFormulário_11_Normas para entrega da versao definitiva dissertacao e ou Tese_Autodeposito assinado.pdf.jpgIM Thumbnailimage/jpeg6942https://repositorio.ufscar.br/bitstream/ufscar/16719/8/Formul%c3%a1rio_11_Normas%20para%20entrega%20da%20versao%20definitiva%20dissertacao%20e%20ou%20Tese_Autodeposito%20assinado.pdf.jpg264d8b2b8cc98d55dcfb6369ee17ae0cMD58ufscar/167192023-09-18 18:32:29.184oai:repositorio.ufscar.br:ufscar/16719Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:32:29Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |
