Relações entre a estrutura da sinúsia herbácea terrícola e a cobertura do dossel em floresta estacional no Sul do Brasil

Abstract: -(Relations between the structure of terrestrial herbaceous synusiae and canopy cover in a seasonal forest in southern Brazil). The terrestrial herbaceous synusiae in tropical and subtropical forests is scarcely studied, mainly concerning its relationship to environmental factors. The aims of this study were to describe the structure of this synusiae in a seasonal forest, in "Parque Estadual do Turvo", in two different seasons and to correlate it to the degree of canopy opening, assessed by hemispherical photo… Show more

“…The annual means of temperature and rainfall are 18-20°C and 1,900-2,000 mm, respectively (Wrege et al 2012). Soils and substrates originate from basaltic rocks and are mostly eutrophic (IBGE 1990;Cunha et al 2006;Giehl and Jarenkow 2008), but those within and nearby ponds tend to be dystrophic (Grasel et al 2020).…”

“…A composição florística e a estrutura de comunidades herbáceas estão condicionadas a alguns fatores, provavelmente não mutuamente excludentes, como por exemplo, altitude, declividade, fertilidade do solo e precipitação (Costa 2004, Costa et al 2005, Inácio & Jarenkow 2008, Lima & Gandolfi 2009. Entretanto, as atividades antrópicas também podem ser consideradas como um fator influenciador da estrutura (por exemplo, riqueza de espécies e de famílias, densidade, diversidade Shannon-Wiener, equabilidade de Pielou e área basal) e da composição das comunidades herbáceas da Caatinga (Santos et al 2006, Benevides et al 2007, Miranda et al 2007, Silva 2011, Feitoza 2013.…”

“…Em ambientes antropizados, existe uma maior disponibilidade de luz, modificando a estrutura do estrato herbáceo (Santos et al 2006, Benevides et al 2007, Silva 2011, Zelarayán et al 2015. Apesar de evidências mostrarem que o desenvolvimento deste estrato é limitado pelo sombreamento (Inácio & Jarenkow 2008, Lima & Gandolfi 2009, Citadini-Zanetti et al 2011, ilhas de vegetação perene podem facilitar o estabelecimento de plantas herbáceas na Caatinga (Silva et al 2015).…”

“…Species within this group allocate higher investments to reproduction and population growth when inhabiting resource-unlimited habitats, compared to long-lived but shade-tolerant species that recruit in the forest understory. Such light-demanding forest species (including the genera Albizia , Alchornea , Ceiba , and Cedrela ) take advantage of the highly illuminated understory underneath a more deciduous canopy in addition to the naturally discontinuous forest canopy in deciduous forest [ 62 ], and may benefit from elevated light levels and drier conditions in edge-affected habitats in forest fragments [ 58 ].…”
