Resumo: | Adaptive responses to the interaction of abiotic factors that operate at different spatial and temporal scales may reflect on the distribution of species, due to their interaction with the environment. This study aimed to check differences in the structure of individuals between populations of Laguncularia racemosa (L.) C. F. Gaertn. (Combretaceae) distributed in mangrove areas and in transition areas between mangrove and restinga forest, using leaf morphological characteristics and plant architecture. Environmental variables were analyzed, such as soil nutrients and salinity level. The transition area showed lower salinity of pore water and soil pH, probably due to the high levels of aluminum. Laguncularia racemosa individuals in the mangrove area had larger leaves than the population in the transition area, with larger leaf area, specific leaf area, and leaf density, and smaller leaf volume. In mangrove, L. racemosa individuals had higher height and basal trunk diameter and lower canopy density and percentage of leaves subject to herbivory, but a higher number of senescent leaves. Such results may be related to the contrasting environmental conditions and significant differences in water salinity and soil nutrients. |

Respostas adaptativas à interação de fatores abióticos que atuam em diferentes escalas espaciais e temporais podem reletir na distribuição das espécies, em decorrência de sua interação com o ambiente. Este estudo teve por objetivo verificar as diferenças na estrutura dos indivíduos entre populações de Laguncularia racemosa (L.) C. F. Gaertn. (Combretaceae) distribuídas em áreas de manguezal e de transição manguezal e restinga, utilizando características morfológicas foliares e arquitetura da planta. Foram analisadas varáveis ambientais, como nutrientes do solo e teor de salinidade. A área de transição apresentou menor salinidade da água intersticial e pH do solo, provavelmente em decorrência dos altos índices de alumínio. Indivíduos de L. racemosa da área de manguezal apresentaram folhas maiores que a população da área de transição, com maior área foliar, área específica foliar, densidade foliar e menor volume foliar. No manguezal, indivíduos de L. racemosa apresentaram maior altura e diâmetro basal do tronco e menor densidade de copa e percentual de folhas herbivoradas, porém, maior número de folhas senescentes. Tais resultados possivelmente relacionam-se com as contrastantes condições ambientais e com expressivas diferenças na salinidade da água e nos nutrientes dos solos.Universidade Federal de Santa Catarina2014-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n1p2110.5007/2175-7925.2015v28n1p21Biotemas; v. 28 n. 1 (2015); 21-292175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n1p21/28671Copyright (c) 2015 Magda Carrion Bartz, João Carlos Ferreira de Melo Júnior, Leticia Larcherinfo:eu-repo/semantics/openAccessBartz, Magda CarrionMelo Júnior, João Carlos Ferreira deLarcher, Leticia2017-10-19T16:47:39Zoai:periodicos.ufsc.br:article/34026Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2017-10-19T16:47:39Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
