Resumo: The objective of this work was to analyze whether remnants of shrub wooded Caatinga with different floristic composition present phytoecological similarities. The study was carried out in two areas: in Seridó Potiguar (Barrentas) and in Cariri Paraibano (Passagem Rasa). We used ramdomly located sample plots for adult tree and regenerating. Forest individuals were measured, and the composition and floristic diversity were analyzed. We found 1,418 individuals in the adult trees stratum distributed into five families, 11 genres and 11 forest species with a density of 5,300 stem ha-1 in Barrentas and 1,565 individuals distributed into 10 families, 20 genres and 26 species with 4,175 stem ha-1 in Passagem Rasa. In natural regeneration we registered 398 individuals, of five families, 10 genres and 12 species in Barrentas and 680 individuals distributed into five families, 10 genres and 11 species in Passagem Rasa. The studied areas presented low floristic and structural similarity , considering the variables density and dominance. In principle, this is due to the greater influence of the edaphoclimatic conditions associated with anthropic factors.

Foram estudadas duas áreas: uma localizada no Seridó Potiguar (Barrentas), e outra no Cariri Paraibano (Passagem Rasa). Através de amostragem aleatória por parcelas fixas, foram mensurados árvores e arbustos do estrato florestal e analisada a composição florística e diversidade. Em Barrentas foram amostrados, no estrato adulto, 1.418 indivíduos, distribuídos em cinco famílias, 11 gêneros e 11 espécies, com uma densidade de 5.300 fustes ha-1 e em Passagem Rasa, 1.565 indivíduos, representando 10 famílias, 20 gêneros e 26 espécies, com 4.175 fustes ha-1. Na regeneração natural, foram inventariados 398 indivíduos de cinco famílias, 10 gêneros e 12 espécies em Barrentas e 680 indivíduos, de cinco famílias, 10 gêneros e 11 espécies em Passagem Rasa. As áreas inventariadas apresentam baixa similaridade florística e estruturais para as variáveis densidade e dominância. Em principio, isso ocorre por maior influência das condições edafoclimáticas associadas a fatores antrópicos.Embrapa Florestas2019-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/151810.4336/2019.pfb.39e201701518Pesquisa Florestal Brasileira; v. 39 (2019)Pesquisa Florestal Brasileira; Vol. 39 (2019)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1518/908https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMarinho, Itaragil VenâncioNóbrega Lúcio, Assíria Maria FerreiraHolanda, Alan CauêFreitas, Cirilo Berson Alves2020-01-02T19:20:11Zoai:pfb.cnpf.embrapa.br/pfb:article/1518Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2020-01-02T19:20:11Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
