“…predominated and was the family with the highest proportion of representatives in this sample (33.3%). Several studies have reported that Fabaceae is one of the most common families in restingas of the northeast (Cantarelli 2003;Sacramento et al 2007;Silva et al 2008;Almeida Jr. et al 2009) and southeast (Araújo & Henriques 1984;Silva & Oliveira 1989;Sá 1992;Araújo 2000;Lemos et al 2001), because it has common representatives in the neotropical flora (Gentry 1988). The Parnaíba restinga presented the highest H' value, ranging from 1.3 to 4.0.…”

“…Pires (2001) correlated this increased capacity to the higher clay content of the soil, as verified in the samples from both areas, thereby explaining their better nutrient levels. The areas of restinga of Pernambuco presented acidic soils, with a mean pH of 4.8 (Sacramento et al 2007;Silva et al 2008), with lower values for the flooded areas (Cantarelli 2003).…”

“…Entre as espécies registradas, nenhuma é restrita a um único bioma, assim como não há espécies exclusivas de restinga. Este comportamento generalista é marcante entre as espécies vegetais que ocorrem ao longo do litoral brasileiro (Assis et al 2004;Silva et al 2008).…”

RESUMOAs dunas costeiras têm sido apontadas como um dos ambientes mais deteriorados do litoral brasileiro ameaçando assim a vegetação de restinga. O objetivo desse estudo foi descrever a fitossociologia do estrato herbáceo da vegetação de Structural characterization and conservation status of the herbaceous stratum at Praia de São Marcos dunes, Maranhão State, Brazil ABSTRACTThe coastal dunes have been identified as one of the most degraded environments. On the Brazilian coast, they threat the "restinga" vegetation. The objective of this study was to describe the phytosociological structure of the herb layer of dune vegetation and assess the conservation status of the area on the Maranhão coast. The study was conducted at São Marcos Beach located in the northern portion of the Maranhão Island. For the phytosociological sampling, we used the plot's method (50 plots of 1 m 2 ), and analyzed the traditional phytosociological parameters of vegetation. Also, there were determined the life forms, phytogeographic distribution and conservation status of vegetation community on site. In the sample of 50 m² we found 35 species from which Paspalum maritimum, Paspalum ligulare, Cassytha filiformis, Chamaecrista hispidula and Euploca polyphylla showed the highest importance value. When calculated for the cover values, the Shannon diversity index (H') was 1.69 nats m -² and it was 3.04 nats m -² when calculated for the frequency values. The area showed predominance of chamaephytes and therophytes indicating an adaptive strategy of vegetation to withstand adverse weather conditions. The sampled ecosystem presented widely distributed species in the Brazilian biomes, being absent endemism. There were identified 14 impacts factors of which five hit more severely the restinga vegetation of the São Marcos Beach. Therefore, more studies are needed with a focus on conservation of dune ecosystems to prevent damage compromising the plant diversity of these areas.

“…The most species rich families encountered in our surveys (Fabaceae, Myrtaceae, Sapotaceae, and Rubiaceae) were also among the most important families reported in other Restinga forest sites (Assumpção & Nascimento 2000;Assis et al 2004;Martins et al 2008;Silva et al 2008). Myrtaceae taxa are typically found on soils with low fertility (Berry 1915) and are important components of Restinga vegetation along the entire coast of Brazil.…”

The Restinga forests of southern Bahia state, Brazil, grow on sandy coastal Quaternary sediments. As their floras are relatively poorly known, the present study assessed their floristic compositions. We surveyed four sites at Maraú and Itacaré and identified 302 angiosperm species belonging to 184 genera of 75 families. The most species rich families were: Fabaceae (35 species), Myrtaceae (25), Rubiaceae (21), Sapotaceae (13), Bromeliaceae (12), Annonaceae (11), Erythroxylaceae (10), Melastomataceae (9), and Apocynaceae (8). Local floras include elements with distributions restricted to the Atlantic Forest domain, those disjunct between the Amazon and Atlantic Forest domains, and those also occurring in moist forests and dry vegetation of central Brazil. The hypothesis that the floristic compositions of restinga forests are influenced by neighboring wet forests was tested using cluster and principal component analyses of eleven restinga forests and nine Atlantic wet forest sites. The results supported five main groups, with most of them including both restinga forests and their adjacent wet forest sites, thus corroborating the hypothesis that wet forests in geographical proximity greatly influence the floristic compositions of restinga forests. Key-word: coastal vegetation, Atlantic Forest domain, flora, similarity. ResumoAs florestas de Restinga do baixo-sul da Bahia, Brasil, encontram-se sobre sedimentos arenosos do Quaternário costeiro. Como sua flora é relativamente pouco conhecida, o presente estudo avaliou sua composição florística. Foram inventariadas quatro áreas nos municípios de Maraú e Itacaré e identificadas 302 espécies de angiospermas, distribuídas em 184 gêneros e 75 famílias. As famílias mais ricas em espécies foram: Fabaceae (35 espécies), Myrtaceae (25), Rubiaceae (21), Sapotaceae (13), Bromeliaceae (12), Annonaceae (11), Erythroxylaceae (10), Melastomataceae (9) e Apocynaceae (8). A flora local inclui elementos de distribuição restrita à Mata Atlântica, disjunta entre Amazônia e Mata Atlântica e florestas úmidas e a vegetação seca do Brasil central. A hipótese de que a composição florística das florestas de Restinga é influenciada pelas florestas pluviais geograficamente próximas foi testada usando análises de agrupamento e de componentes principais com onze áreas de florestas de Restinga e nove de florestas pluviais da Mata Altântica. Os resultados sustentaram cinco grupos principais, a maioria incluindo áreas de floresta de restinga e florestas pluviais adjacentes, corroborando a hipótese de que a proximidade geográfica aos estoques florísticos das florestas pluviais tem grande efeito na composição das florestas de Restinga. Palavras-chave: vegetação costeira, Domínio Mata Atlântica, flora, similaridade.
