Structure of the herb stratum under different light regimes in the Submontane Atlantic Rain Forest

Abstract: This study aimed to characterize the structure of the herb stratum in relation to light availability in the Submontane Atlantic Rain Forest at the Carlos Botelho State Park, SP, Brazil. Forty-one 10 x10 m plots were established under the closed canopy (18 plots), small and medium canopy gaps (11) and large canopy gaps dominated by Guadua tagoara (Ness) Kunth (12). Inside each plot, the line intercept method was applied to assess soil coverage as an estimate of density of herb stratum vegetation. Hemispherical … Show more

“…The canopy is markedly lower and discontinuous, enhancing light entrance (Lima and Gandolfi, 2009). In the studied plot, the taquarais are formed solely by G. tagoara (Nees) Kunth, a largesized, semi-scandent woody bamboo.…”

“…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).…”

“…The recruitment of plants below a nurse plant can be influenced by changes in microenvironmental conditions (Callaway 1995). Nurse plants can reduce the amount of light that reaches the soil and thus reduce its temperature (Padilla and Pugnaire 2006;Lima and Gandolfi 2009). Nurse plants are responsible for increasing the availability of water, as well as improving the levels of nutrients available in the soil through the liberation of organic material under their canopies (Koorem and Moora 2010; Liu et al 2014;Ramírez et al 2015;Mihoč et al 2016;Pueyo et al 2016).…”
