Resumo: | The Atlantic Forest biodiversity is considered of extreme biological importance; however, its fauna and flora richness has been threatened by deforestation. This study aimed to present a model for assessing biodiversity loss, considering the municipality of Viçosa do Ceará (northeastern Brazil) as the study area. The used method is based on the proposal of an indicator, from which, we sought to calculate the estimate of biodiversity loss through the decrease in the richness of birds, mammals, and scaly reptiles in the studied habitat, using the species-area relationship model as a reference. The following results were obtained: (1) the biodiversity loss in the study area is at an “extreme” level; (2) the rates of average variation and speed have accelerated movement, therefore, the greater the increase of deforested area, the faster the speed and acceleration of biodiversity loss; (3) the curvature of the function indicated that the critical point of biodiversity loss is reached when deforestation reaches 93% of the ecosystem area. It was concluded that the model used to estimate the loss of birds, mammals, and scaly reptiles was efficient to assess biodiversity loss in the Atlantic Forest ecosystem. |

O objetivo deste estudo consiste em apresentar um modelo de avaliação da perda da biodiversidade, adotando como cenário o município de Viçosa do Ceará, situado no Nordeste brasileiro. O método adotado baseia-se na proposição de um indicador em que se busca calcular a estimativa da perda da biodiversidade a partir do decréscimo da riqueza de aves, mamíferos e répteis escamados que fazem parte desse habitat, tendo como referência o modelo da relação espécie-área. Como resultados tem-se: (1) a perda da biodiversidade na área de estudo está em nível “extremo”; (2) as taxas de variação média e de velocidade têm movimento acelerado, logo, quanto maior for o aumento da área desmatada, mais rápida se torna a velocidade e aceleração da perda da biodiversidade; (3) a curvatura da função indicou que o ponto crítico da perda da biodiversidade acontece quando o desmatamento atinge 93% da área do ecossistema. Conclui-se que o modelo de estimativa da perda de aves, mamíferos e répteis escamados apresentou-se de forma eficiente para a avaliação da perda da biodiversidade no ecossistema de Mata Atlântica.Universidade Federal de Santa Maria2021-11-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmltext/xmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/5331010.5902/1980509853310Ciência Florestal; Vol. 31 No. 4 (2021); 1885-1909Ciência Florestal; v. 31 n. 4 (2021); 1885-19091980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/53310/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/53310/49134https://periodicos.ufsm.br/cienciaflorestal/article/view/53310/52469Copyright (c) 2021 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessBranco, Antonia Francivan Veira CasteloLima, Patrícia Verônica Pinheiro Sales LimaMedeiros Filho, Esdras Soares deCosta, Benedita Marta GomesPereira, Tarcisio Praciano2023-04-20T18:13:22Zoai:ojs.pkp.sfu.ca:article/53310Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-04-20T18:13:22Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
