Resumo: | Inside the Brazilian semi-arid region (Caatinga biome) there are vegetation refuges from other biomes that are present mainly at greater elevations in ancient geological formations such as Chapada do Araripe. This study aimed to understand the structure, diversity and floristic similarity of a fragment of humid forest in order to support conservation strategies for this community in Chapada do Araripe, southern Ceará (708m Alt.), an area of relevant ecological, cultural and scenic value. In 13 parcels of 25x25m (0.8 ha) all individuals with DBH ≥ 5cm were inventoried, observing total height. Floristic similarity was observed using the Jaccard method, comparing it with seven other areas in different regions of the Brazil. Sixty-six species were found distributed in 34 families, in a total of 1,544 individuals with DA=1,997.30 ind.ha-1 and AB =32,618 m²ha-1. Fabaceae (25.75%) and Myrtaceae (6%) had the highest number of species and Brosimum gaudichaudii had the highest IVI. The Shannon index (H') was 3.13 and the Pielou equability (J') was 0.75. The beta diversity, compared with other areas of humid forest (core and disjunct), was considered high and the statistics showed greater similarity with the area of the mesoregion of Pernambuco forest. The results allow the characterization of the area as a vegetational refuge of humid forest, corroborating the Refuge Theory and showing strong penetration of savanna species (“Cerradão”, Cerrado, Caatinga/“Carrasco”), emphasizing the action of climatic impulses that occurred in the Quaternary and pointing to the need to conservation strategies due to accelerated anthropism. |

Este trabalho objetivou o conhecimento da estrutura, diversidade e similaridade florística de um fragmento de mata úmida na Chapada do Araripe, sul do Ceará (708m Alt.), visando subsidiar estratégias de conservação dessa comunidade, área de relevante valor ecológico, cultural e paisagístico. Em 13 parcelas de 25x25m (0,8 ha), foram inventariados todos os indivíduos com DAP ≥ 5cm, observando-se altura total. A similaridade florística foi observada pelo método de Jaccard a partir da comparação com outras sete áreas em diferentes regiões do Brasil. Foram encontradas 66 espécies distribuídas em 34 famílias, num total de 1.544 indivíduos com DA=1.997,30 ind.ha-1 e AB=32,618 m²ha-1. Fabaceae (25,75%) e Myrtaceae (6%) apresentaram maior número de espécies e Brosimum gaudichaudii apresentou maior IVI. O índice de Shannon (H’) foi 3,13 e a equabilidade de Pielou (J’) foi 0,75. A diversidade beta, comparada com outras áreas de mata úmida (core e disjuntas), foi considerada alta e a estatística apontou maior similaridade com área da mesorregião da mata pernambucana. Os resultados permitem caracterizar a área como refúgio vegetacional de mata úmida, corroborando com a teoria dos refúgios e evidenciam forte penetração de espécies savânicas (cerradão, cerrado, caatinga/carrasco) enfatizando a atuação de impulsos climáticos ocorridos no Quaternário e apontando para a necessidade de estratégias de conservação devido ao antropismo acelerado.Universidade Federal de Santa Maria2023-09-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6909710.5902/1980509869097Ciência Florestal; Vol. 33 No. 3 (2023): Publicação Contínua; e69097Ciência Florestal; v. 33 n. 3 (2023): Publicação Contínua; e690971980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/69097/61683Copyright (c) 2023 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessBenício, Roberta Maria ArraisNascimento, Arthur da SilvaMorais, Sarah Caroline de OliveiraLisboa, Maria Amanda NobreSilva, Leonardo Vitor Alves daCruz, Gabriel VenâncioMorais, Helen Nogueira deAraújo, Isaac FeitosaLinhares, Karina VieiralvesSilva, Maria Arlene Pessoa daRocha, Leonardo Silvestre GomesCalixto Júnior, João Tavares2023-09-19T21:44:01Zoai:ojs.pkp.sfu.ca:article/69097Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-09-19T21:44:01Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
