Estrutura comunitária e amplitude ecológica do componente lenhoso de uma floresta de restinga mal drenada no sudeste do Brasil

Abstract: Acta bot. bras. 24(3): 825-839. 2010. IntroduçãoNo Brasil, principalmente nas regiões sul e sudeste, as restingas têm sido alvo de estudos mais sistematizados, sobretudo levantamentos fl orísticos e estruturais, que evidenciam a importância desses ecossistemas para a biodiversidade. Tal importância reside no fato das espécies que ocorrem nas restingas serem, na sua maioria, formas adaptadas de espécies oriundas da mata tropical chuvosa e que se estruturam em comunidades através de processos de interação positi… Show more

“…However, the basal area of dead trees in Itaúnas was similar to that found for those well-drained restingas and lower than that found for the poorly drained Marambaia restinga (1.28 m²/ha). Th is can be attributed to the fact that fl ooding creates soil conditions that restrict tree development (Menezes et al 2010). In addition, the signifi cant diff erence between our fi ndings and those of other studies of restingas, in terms of the density of dead trees, can be attributed to the inclusion criterion adopted in our study (DBH ≥ 2.5, a diameter smaller than that used in other studies).…”

“…In the Itaúnas restinga, dead trees, if they were to be considered in a specifi c category, would rank 4th in IV, with a density of 214 ind./ ha. Th is value is higher than that found for restingas with well-drained soils along the coast-such as the 58.9 ind./ha reported for the Tavares restinga, in the state of Rio Grande do Sul (Dorneles & Waechter 2004); the 67.0 ind./ha and 104.0 ind./ha reported for the restingas in Paulo César Vinha State Park, in Espírito Santo (Assis et al 2004b;Fabris 1995); and the 120.0 ind./ha reported for the Armação de Buzios restinga, in the state of Rio de Janeiro (Lobão & Kurtz 2000)-as well as that found for poorly drained restingas, such as the 152.0 ind./ha reported for the Marambaia restinga, in the state of Rio de Janeiro (Menezes et al 2010). However, the basal area of dead trees in Itaúnas was similar to that found for those well-drained restingas and lower than that found for the poorly drained Marambaia restinga (1.28 m²/ha).…”

“…Those stressors restrict the establishment of species at the Gávea site, as reported by Scarano (1998), who studied the dispersal, germination and establishment of plants subjected to different flooding regimes and the consequences of the oxygen deficit imposed by flooded soils. Studies performed in areas of restinga showed that floodplain vegetation formations display a lower richness of plant species than upland vegetation formations (Almeida Jr. et al 2009, Guedes et al 2006, Menezes et al 2010. Therefore, variations in the frequency and intensity of soil waterlogging can be considered determinants of the structural and floristic characteristics of the vegetation.…”

“…Therefore, variations in the frequency and intensity of soil waterlogging can be considered determinants of the structural and floristic characteristics of the vegetation. Such variations might also result in altered behavior for certain populations (Rodrigues & Shepherd 2000;Menezes et al 2010).…”
