Resumo: The present study aimed to update the categorization of the extinction risk of Discocactus bahiensis Britton & Rose and Discocactus zehntneri Britton & Rose, endemic Cactaceae species from Northeastern Brazil. The georeferenced species occurrence points were obtained from the online databases speciesLink and Global Biodiversity Information Facility (GBIF). Polygons were traced using these points, being gridded with 4 km² cells and virtually divided in half (2 km²). Afterwards, the cells occupied by the species were counted in order to obtain their occupation areas. The species D.bahiensis presented 17 records and an occupation area of 32 km², while D.zehntneri presented 15 records and an occupation area of 24 km². The sites where the species are found present different factors of anthropic pressure. Thus, the species D.bahienses and D.zehntneri were categorized as “Endangered”, according to the B2biiicii criteria.

Os pontos de ocorrência georreferenciados das espécies foram obtidos nas bases de dados online speciesLink eGlobal Biodiversity Information Facility (GBIF). Com esses pontos foram traçados polígonos que foram gradeados com células de 4 km² e divididas virtualmente pela metade (2 km²). Posteriormente foram contabilizadas as células ocupadas pelas espécies para a obtenção das áreas de ocupação das mesmas. A espécieD. bahiensis apresentou17 registros e uma área de ocupação de 32 km², enquanto D. zehntneri apresentou 15 registros e uma área de ocupação de 24 km². Os locais nos quais as espécies são encontradas apresentam diversos fatores de pressão antrópica. Assim, as espécies D. bahienses e D. zehntneri foram categorizadas como “Em perigo” de acordo com os critérios B2biiicii. Universidade Federal de Campina Grande - UFCG2022-01-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/56910.22571/2526-4338569Acta Brasiliensis; Vol 6 No 1 (2022): Acta Brasiliensis; 14-16Acta Brasiliensis; Vol 6 No 1 (2022): Acta Brasiliensis; 14-16Acta Brasiliensis; Vol 6 No 1 (2022): Acta Brasiliensis; 14-162526-43382526-432Xreponame:Acta Brasiliensis (Online)instname:Universidade Federal de Campina Grande (UFCG)instacron:UFCGenghttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/569/139Copyright (c) 2022 Acta Brasiliensisinfo:eu-repo/semantics/openAccessCruz, Anny Bianca SantosReis, Daniel OliveiraFabricante, Juliano Ricardo2022-01-31T23:17:40Zoai:ActaBra.revistas.ufcg.edu.br:article/569Revistahttp://revistas.ufcg.edu.br/ActaBraPUBhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/oaiactabrasiliensis@gmail.com || actabrasiliensis@gmail.com2526-432X2526-4338opendoar:2022-01-31T23:17:40Acta Brasiliensis (Online) - Universidade Federal de Campina Grande (UFCG)false
