“…Assim, o solo tornou-se um fator chave para a composição florística da vegetação de restinga (Silva 1990), a qual também sofre grande influência pela proximidade do mar e pelo constante déficit hídrico, limitantes, principalmente, à colonização das espécies nas formações imediatas à praia (Daniel 2006), como observado pela menor diversidade na Rh e Ra neste estudo. O pH ácido do solo na área de estudo é tido como um fator que pode afetar o estabelecimento das comunidades vegetais (Santos-Filho et al 2013) e reduzir as taxas de decomposição no solo (Silva 1990), o que justifica o maior teor de matéria orgânica (MO) obervado no Espodossolo na Ft.…”

“…No entanto, são raros os estudos que investigam o papel determinante das variáveis de solo sobre a estruturação das comunidades de restinga. Pesquisas com esse objetivo foram realizadas em restingas de outros Estados brasileiros, como Espírito Santo (Fabris 1995, Magnano et al 2010, Paraná (Britez et al 1997, Britez 2005, Pernambuco (Almeida Jr. et al 2011), Piauí (Santos-Filho et al 2013), Rio Grande do Sul (Costa et al 2003) e São Paulo (Sztutman & Rodrigues 2002, Guedes et al 2006) e identificaram diferenças estruturais nas comunidades vegetais ao longo da restinga em virtude das variações edáficas.…”

-(Richness, structure, and edaphic interactions in the restinga gradient of Parque Estadual do Acaraí, Santa Catarina State, Brazil). The present work characterized the flora and phytocommunities of a restinga gradient on the coast plain of Santa Catarina State and correlated them to edaphic attributes. The floristic survey followed the wide patrolling method and the community structure was determined through the plot method. Soil samples of each physiognomy were collected for analysis of macronutrients, organic matter, moisture, and litter thickness. Flora comprises 319 species, 244 of which occur exclusively in formations of herbaceous restinga (63), shrub restinga (32), shrub-tree restinga (46), and transition forest (103). The structural pattern of each restinga physiognomy studied was influenced by edaphic factors as organic matter, potassium, and aluminum contents, cation exchange capacity, and litter thickness. These attributes are determinant for the flora characterizing each phytocommunity.

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.

“…The necessity to expand the knowledge of soils under native vegetation and their relationship has been recognized as a research priority by several researchers (Lima et al, 2011;Cooper et al, 2012;Santos-Filho et al, 2013). The close relationship between soil attributes and forest composition has long been reported in the literature (Sollins, 1998), and SHP have been considered an important factor to be considered in studies involving soil-plant relationships (Ruggiero et al, 2002;Quesada et al, 2004;Oliveira et al, 2005).…”

Knowledge of the hydraulic properties of the soil is of crucial importance to an understanding of the interactions between vegetation, soil and water. There is little information available about the hydraulic properties of Podzol soils found in tropical regions. The aim of this study was to present the soil morphology and hydraulic properties of a toposequence situated in a permanent plot at the Ilha do Cardoso State Park (Cananéia, SP, Brazil). Ultradetailed soil maps were used to define a toposequence inside the permanent plot. Five profiles, representing the main types of soil, were opened along the toposequence, in which Podzols are dominant.The levels of bulk density, sand content, porosity and permeability in these soils were all high.Consequently, these soils have a high level of hydraulic conductivity with low water retention. This behavior undergoes an alteration in the Bh and Bs horizons due to the accumulation of organic and metallic compounds and a changing structure that modifies the pore distribution. Furthermore, the characterization of the hydro-physical functioning of soils in natural environments is an important source of encouragement to further investigative study of soil water dynamics and its relationship to the native vegetation.
