Energy reserves of Artibeus lituratus (Chiroptera: Phyllostomidae) in two areas with different degrees of conservation in Minas Gerais, Brazil

Forest fragmentation associated with the expansion of human development is a phenomenon that occurs worldwide. Studies reveal that there have been both a decline in species diversity and a decrease in Neotropical bat population size because of habitat loss. The aim of this study was to investigate w...

Studies reveal that there have been both a decline in species diversity and a decrease in Neotropical bat population size because of habitat loss. The aim of this study was to investigate whether human action has been affecting the food availability to wildlife species, which could impact the storage of body energy reserves. For this purpose, fruit-eating bats (Artibeus lituratus) were collected in two areas in Minas Gerais state, Brazil. The concentrations of plasma glucose, as well as glycogen, lipids and protein in liver in muscles were performed, in addition to adipose tissue weight and carcass fatty acids. Our results indicate that fat reserves were significantly lower in most tested tissues (muscle of the hindlimbs, breast muscles, adipose tissue and carcass) in animals collected in the region with a higher degree of human disturbance. The other parameters showed no significant differences in the groups collected at different locations. In conclusion, we suggest that human action on the environment may be affecting the storage of body fat energy reserves of this species during the autumn, particularly in metropolitan region areas of Belo Horizonte, MG - Brazil, requiring special attention to the species conservation.A fragmentação florestal associada à expansão do desenvolvimento humano é um fenômeno que ocorre em todo o mundo. Estudos revelam que vêm ocorrendo tanto uma diminuição da diversidade de espécies quanto uma diminuição no tamanho das populações de morcegos neotropicais em função da perda de habitat. Com o objetivo de comparar o armazenamento das reservas energéticas em duas áreas com diferentes graus de conservação, morcegos frugívoros da espécie Artibeus lituratus foram coletados durante o outono de 2009 em duas áreas no Estado de Minas Gerais, Brasil. Foram determinadas as concentrações de glicose plasmática e de glicogênio, proteína e lipídio hepáticos e musculares, além das concentrações lipídicas do tecido adiposo e ácidos graxos totais da carcaça. As reservas lipídicas apresentaram concentrações significativamente menores na maior parte dos tecidos testados (músculo das patas posteriores, músculo peitoral, tecido adiposo e carcaça) nos animais coletados na região menos preservada. Os outros parâmetros não apresentaram diferenças significativas nos grupos coletados nos diferentes locais. Em conclusão, pode-se inferir que a ação humana sobre os ambientes pode estar afetando o armazenamento de reservas energéticas corporais lipídicas de machos dessa espécie, particularmente em áreas da região metropolitana de Belo Horizonte-MG, Brasil, durante o outono.Brazilian Journal of Biology2017-10-26T11:31:52Z2017-10-26T11:31:52Z2012-02-29info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf15196984http://dx.doi.org/10.1590/S1519-69842012000100022http://www.locus.ufv.br/handle/123456789/12425engv.72, n.1, p. 181-187,Feb. 2012info:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVMelo, BES.Carvalho, TF.Amaral, TS.Freitas, MB.Barros, MS.2024-07-12T07:40:48Zoai:locus.ufv.br:123456789/12425Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T07:40:48LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
