| Popis: | O presente estudo teve como objetivo analisar os parâmetros estruturais da vegetacao arbustivo-arborea da restinga de Marechal Deodoro. O estudo foi realizado em uma area do litoral sul do Estado de Alagoas, no municipio de Marechal Deodoro (09o42’36’’S e 35o53’42’’W). Para amostragem foram instalados cinco transectos de 100m, perfazendo 50 pontos, cujo criterio de inclusao de especies foi de PAS 10cm e os parâmetros fitossociologicos foram analisados para as especies. Foram amostradas 49 especies, distribuidas em 39 generos e 29 familias, perfazendo 200 individuos. As familias com maior riqueza especifica foram Myrtaceae (sete especies), Fabaceae (4), Anacardiaceae (3), Sapotaceae (3), Chrysobalanaceae (2), Clusiaceae (2), Malpighiaceae (2), Rutaceae (2) e Sapindaceae (2). As especies de maior IVI foram Manilkara salzmannii, Tapirira guianensis, Marlierea regeliana, Protium heptaphyllum e Andira nitida. O indice de Shannon encontrado foi de 3,330 nat.ind-1, valor proximo ao dos estudos realizados no litoral de Pernambuco. As especies encontradas sao comuns as restingas do Nordeste apresentando consideravel diversidade floristica, apesar da pressao antropica. Palavras-chave: Fitossociologia, Nordeste, vegetacao de restinga, riqueza floristica. Structure of the Woody Component of a Restinga on the South Coast of Alagoas, Northeastern Brazil ABSTRACT This study aimed to analyze the structural parameters of shrub-arboreal Marechal Deodoro restinga. The study was conducted in a southern coastal in Alagoas State, in the municipality of Marechal Deodoro (09o42'36''S and 35o53'42''W). For sampling were installed five 100m transects, totaling 50 points, the inclusion criterion of species was PSL ≥ 10cm and the phytosociological parameters were analyzed for the species. We sampled 49 species belonging to 39 genera and 29 families, totaling 200 individuals. The families with greater specific richness were Myrtaceae (seven species), Fabaceae (4), Anacardiaceae (3), Sapotaceae (3) Chrysobalanaceae (2), Clusiaceae (2) Malpighiaceae (2), Rutaceae (2) and Sapindaceae (2). Species with higher IVI were Manilkara salzmannii , Tapirira guianensis Marlierea regeliana , Protium heptaphyllum and Andira nitida . The Shannon index was found to be 3.330 nats.ind-1, value close to those studies conducted on the coast of Pernambuco. The species found are common to salt marshes of the Northeast showing considerable floristic diversity, despite the anthropogenic pressure. Keywords: Phytosociology, Northeast, restinga vegetation, floristic richness. |
