“…Combined with the low‐water retention sandy soils that prevail along the coastal plains (Marques et al. ) and the strong trade winds that increase evapotranspiration, these gradients imply hot and drought‐prone conditions in the northeastern portion of the coast. Climatic factors are known to be determinant to the broad‐scale distribution of species (Guisan and Thuiller , Sexton et al.…”

“…These conditions impose severe limitations to plant growth (Marques et al. ). A number of researchers have found that soil nutrients, aluminum content, acidity, percentage of sand, and amount of organic matter are related to changes in heath vegetation physiognomy from marsh to scrub to forest (Silva et al.…”

“…Adaptations to poor soil conditions have been found in restinga species like shallow root systems, aluminum toxicity avoidance through accumulation in the roots or silicate compounds in leaves, timing of phenological events to optimize nutrient cycling, and small leaves with increased thickness (Marques et al. ). We hypothesize that these adaptations will be more common among species in herbaceous archetypes 1, 2, and 5, and in woody archetypes 6, 8, and 11, which showed more pronounced responses to soil nutrient and acidity variation.…”

Common species correspond to most of the structure and biomass of ecosystems, but the determinants of their distributions and the extent of their overlap are still a matter of debate. Here, we tested the hypotheses that (1) common herbaceous and woody species do not respond individualistically to environmental factors, but rather form groups of species with similar environmental affinities (archetypes), and (2) if local communities comprised cohesive systems, then archetypes of common species will occupy distinct portions of the coast with little or no overlap. We used a large set of climatic and soil variables in restinga heath vegetation along ~9000 km of eastern South American coastal plains. We used species archetype models, a new statistical approach that clusters species based on their environmental responses. We found five herbaceous species archetypes and 11 woody species archetypes, all responsive significantly although weakly to a mixture of climatic and soil variables. In most cases, there was considerable spatial overlap of different archetypes rather than separation along the coastline. Common species form groups with similar environmental affinities, but that did not respond strongly to environmental factors. This suggests an important role for dispersal in the explanation of heath vegetation floristic variation. Local community composition is influenced by groups of species that are not unique to any region and overlap extensively. Restinga heath vegetation communities seem to be considerably individualistic rather than cohesive systems.

“…É importante destacar que, dependendo da intensidade da perturbação, a vegetação de restinga apresenta potencial para regeneração natural, porém ainda não se sabe como áreas intensamente impactadas respondem ao processo de recuperação (Marques et al 2015) ressaltando-se que o solo das restingas, pobre em nutrientes e com elevado grau de salinidade, dificulta a recomposição da vegetação (Rocha et al 2003).…”

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.
