Resumo: | The goal of this work was to characterize the physiognomy and structure of the woody component of an area of caatinga vegetation in the Estação Ecológica (ESEC) of Aiuaba, Ceará state, thereby contributing to the knowledge of the vegetation of semiarid northeastern Brazil. Fifty sampling plots (10x10m) were randomly established in a 1.5 hectare area, where stem diameter at soil level was ? 3 cm and height was ? 1 m. The survey results included 3,007 individuals from 47 species and 20 families. Fabaceae, Euphorbiaceae, Erythroxylaceae, Acanthaceae, Bignoniaceae and Rutaceae represented 66% of the species, and the first three families represented 63% of the total importance value. Croton argyrophylloides Müll. Arg., Pityrocarpa moniliformis Benth., Erythroxylum caatingae Plowman and Bauhinia cheilantha (Bong.) Steud. were the most important species. Average plant height was 4.51 m, with a maximum of 13 m; average stem diameter was 7.28 cm, with a maximum of 44.88 cm. The total basal area was 18.3 m2 ha-1. The plant community can be classified as a type of caatinga with shrubs and trees, presenting similar floristic composition to other caatinga vegetation in areas of sandy sediments, and to non-thorn deciduous vegetation (“carrasco”) situated in the Ibiapaba-Araripe Complex. |

Foram alocadas 50 parcelas de 10 x 10 m em uma área de 1,5 ha e medidos os caules de todos os indivíduos, inclusive cipós, que tivessem diâmetro ao nível do solo ? 3 cm e altura total ? 1 m. Foram amostrados 3.007 indivíduos distribuídos em 47 espécies e 20 famílias. Fabaceae, Euphorbiaceae, Erythroxylaceae, Acanthaceae, Bignoniaceae e Rutaceae responderam por 66% das espécies e as três primeiras totalizaram 63% do valor de importância total. Croton argyrophylloides Müll. Arg., Pityrocarpa moniliformis Benth., Erythroxylum caatingae Plowman e Bauhinia cheilantha (Bong.) Steud. tiveram os maiores valores de importância. Os valores médios e máximos de altura e diâmetro, respectivamente, foram 4,51-13 m e 7,28-44,9 cm. A área basal total foi de 18,3 m2ha-1. A comunidade vegetal estudada permitiu enquadrar a vegetação como Caatinga arbustivo-arbórea, apresentando composição florística similar a outras áreas de caatinga instaladas sobre sedimentos arenosos e com áreas de carrasco situadas no Complexo Ibiapaba-Araripe.Universidade Federal de Santa Catarina2015-03-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n2p3910.5007/2175-7925.2015v28n2p39Biotemas; v. 28 n. 2 (2015); 39-502175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n2p39/29241Copyright (c) 2015 Jesus Rodrigues Lemos, Marico Meguroinfo:eu-repo/semantics/openAccessLemos, Jesus RodriguesMeguro, Marico2017-10-19T16:35:45Zoai:periodicos.ufsc.br:article/35130Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2017-10-19T16:35:45Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
