Resumo: Association of pteridophyte species in two fragments of Atlantic Coastal Forest in the Brazilian Northeast. This study aims to investigate fern flora similarity and fern species relationships in the study areas, in terms of their substrates, habitat types, and life forms. The study was conducted in the Água Azul forest fragment, municipality of Timbaúba, Pernambuco, and the Maria Maior forest fragment, municipality of São José da Laje, Alagoas. The Jaccard similarity index was used for cluster analysis. The 112 species that occur in the two areas were used for numerical analysis. The floristic similarity  was great (J=43.75%), principally due to similarities in the two areas vege- tational types, as was expected due to their geographic proximity to one another and their similar climatic conditions. Five groups of associated species were determined for the Água Azul fragment and six groups for the Maria Maior fragment. In general, the ecological factors that determined fern species associations were habitat and type of substrate.

O estudo foi desenvolvido em dois  frag- mentos de Floresta Atlântica Nordestina (fragmento Água Azul, município de Timbaúba, Pernambuco e fragmento Maria Maior, município de São José da Laje, Alagoas). Para a análise de agrupamento foi utilizado o índice de simila- ridade de Jaccard. Para a análise numérica foi utilizada uma lista com 112 espécies referentes ao inventário das áreas. A similaridade florística entre os fragmentos foi elevada (J=43,75%), principalmente pelas semelhanças entre as formações vegetacionais, relacionadas pela proximidade geográfica e pelas características micro-climáticas. Foi possível estabelecer cinco grupos para o fragmento Água Azul e seis para o fragmento Maria Maior. Em geral, os aspectos ecológicos que determinaram os agrupamentos das espécies foram os ambientes de ocorrência e o substrato terrícola, que são predominantes nos dois fragmentos.Universidade Federal de Santa Catarina2006-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21121Biotemas; v. 19 n. 3 (2006); 15-262175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21121/19076Copyright (c) 2006 Marcio Roberto Pietrobom, Iva Carneiro Leão Barroshttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPietrobom, Marcio RobertoLeão Barros, Iva Carneiro2022-11-21T11:44:27Zoai:periodicos.ufsc.br:article/21121Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-21T11:44:27Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
