Resumo: The semiarid region of Rio Grande do Norte State in the Northeast region of Brazil can be divided into two main geoenvironmental units: Sertaneja Depression and Potiguar Sedimentary Basin. Although the flora of sandy sedimentary basins is usually different from that of crystalline terrains, part of the Potiguar Basin has stony paleo-alluvial deposits, with rolled pebbles, imposing different edaphic conditions to the species. The Floresta Nacional de Açu is located on a stretch of the edge of the Potiguar Basin with pebble deposits, which make the soil stony. The objective of this work was to characterize the phytosociological structure of the caatinga in Floresta Nacional de Açu and its surroundings and to understand the biogeographic links of the local flora with other areas of the Caatinga. We selected areas in the interior and surroundings of FLONA and sampled 1,500 woody individuals, belonging to 33 species. The biogeographical links show that the stony edge of the Potiguar Basin is closer to the flora of the crystalline terrains than to the sandy terrains of other sandy sedimentary basins.

Embora a flora das bacias sedimentares arenosas normalmente seja diferente daquela dos terrenos cristalinos, parte da Bacia Potiguar possui depósitos paleo-aluvionares pedregosos, com seixos rolados, impondo à flora condições edáficas diferentes. A Floresta Nacional de Açu está localizada em um trecho da borda da Bacia Potiguar com depósitos de seixos, que tornam o solo pedregoso. O objetivo deste trabalho foi caracterizar a estrutura fitossociológica da caatinga na FLONA e arredores e compreender os vínculos biogeográficos da flora local em relação a outras áreas da Caatinga. Selecionamos áreas no interior e arredores da FLONA e amostramos 1500 indivíduos lenhosos, pertencentes a 33 espécies. Os vínculos biogeográficos mostram que a borda pedregosa da Bacia Potiguar tem mais proximidade com a flora dos terrenos cristalinos do que com terrenos arenosos de outras bacias sedimentares arenosas.SciELO PreprintsSciELO PreprintsSciELO Preprints2021-06-02info:eu-repo/semantics/preprintinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://preprints.scielo.org/index.php/scielo/preprint/view/242510.1590/2236-8906-22/2020porhttps://preprints.scielo.org/index.php/scielo/article/view/2425/4129Copyright (c) 2021 Carla Daniela Guedes Paiva, Marcelo Freire Moro, Leandro de Oliveira Furtado de Sousa, Cristina Baldaufhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess Paiva, Carla Daniela GuedesMoro, Marcelo Freire Sousa, Leandro de Oliveira Furtado deBaldauf, Cristina reponame:SciELO Preprintsinstname:SciELOinstacron:SCI2021-06-02T00:30:02Zoai:ops.preprints.scielo.org:preprint/2425Servidor de preprintshttps://preprints.scielo.org/index.php/scieloONGhttps://preprints.scielo.org/index.php/scielo/oaiscielo.submission@scielo.orgopendoar:2021-06-02T00:30:02SciELO Preprints - SciELOfalse
