Resumo: | This study proposes to reconstruct the paleoenvironment from Quaternary sites of the caves in the sertão baiano and Lagoa Santa region during the Pleistocene. The paleofauna of bats from these sites were compared to the extant fauna of 25 localities, representing most important Neotropical biome. This study was possible because all bat fossil species from both sites were elements of the extant Neotropical fauna, excepting Desmodus draculae. Because bats are considered good environmental definers, the association of extant and fossil fauna permits the recognition of similar environments. The similarity between faunas was analyzed by Jaccard index with a posterior grouping analysis by UPGMA. The paleofauna of Lagoa Santa matched to Caatinga fauna, suggesting a dry and open environment adjacent to the Lagoa Santa caves during the Pleistocene. The paleofauna of sertão baiano caves matched to neither of the analyzed faunas. Most authors suggest that fossil record of the sertão baiano caves represents a faunal mixture. The dissimilarity between the paleofauna of bats from the sertão baiano caves and the other analyzed faunas resulted of this study is in agreement to the argument of a faunal mixture represented by the former. |

As paleofaunas de morcegos desses sítios foram comparadas com a fauna atual de 25 localidades, representando os principais biomas Neotropicais. Tal estudo foi possível, pois todas espécies de morcegos fósseis desses sítios fazem parte da fauna Neotropical atual, excetuando-se Desmodus draculae. Como os morcegos são ótimos caracterizadores ambientais, a associação das faunas atuais e fossilíferas permite reconhecer ambientes semelhantes. A similaridade entre as faunas foi verificada pelo Índice de Jaccard, com posterior análise de agrupamento por média não-ponderada (UPGMA). A paleofauna de Lagoa Santa agrupou-se com a fauna de Caatinga, sugerindo um ambiente seco e aberto para o entorno das grutas de Lagoa Santa durante o Pleistoceno. A paleofauna das grutas do sertão baiano não agrupou com nenhuma das faunas incluídas na análise. Muitos autores sugerem que o registro fossilífero destas grutas seja produto de mistura faunística. A dissimilaridade encontrada neste estudo entre paleofauna de morcegos das grutas baianas com as demais faunas analisadas corrobora o argumento de mistura faunística.Universidade Federal do Rio de JaneiroAvilla, Leonardo SantosWinck, Gisele ReginaFrancisco, Vanessa Maria RodriguesGil, Bruno BretGranhen, AlexandreCosta, Débora Gabriel2007-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/669210.11137/2007_1_19-26Anuário do Instituto de Geociências; Vol 30, No 1 (2007); 19-26Anuário do Instituto de Geociências; Vol 30, No 1 (2007); 19-261982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/6692/5289Copyright (c) 2007 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2022-10-20T18:32:38Zoai:www.revistas.ufrj.br:article/6692Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2022-10-20T18:32:38Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false |
