Abstract: root biomass and root length density in a lowland and a montane tropical rain forest, SP, Brazil. Biota Neotrop. 11(3): http://www.biotaneotropica.org.br/v11n3/en/abstract?article+bn03411032011Abstract: Fine roots, <2 mm in diameter, are responsible for water and nutrient uptake and therefore have a central role in carbon, nutrient and water cycling at the plant and ecosystem level. The root length density (RLD), fine root biomass (FRB) and vertical fine root distribution (VRD) in the soil profile have been us… Show more

“…Similar dynamics were repeatedly observed on single plants (e.g. Doussan et al., ; Garrigues et al., ; Lai & Katul, ; Rosado et al., ) and is in accordance with models of root water uptake (Bechmann et al., ; Doussan et al., ; Schneider et al., ). For instance, Doussan et al.…”

“…Similar dynamics were repeatedly observed on single plants (e.g. Doussan et al, 2006;Garrigues et al, 2006;Lai & Katul, 2000;Rosado et al, 2011) and is in accordance with models of root water uptake (Bechmann et al, 2014;Doussan et al, 2006;Schneider et al, 2009). For instance, Doussan et al (2006) showed that the contribution of different parts of the root system to total water uptake changes dynamically with time and depends on hydraulic properties and arrangement of the root system.…”

“…Garay et al (1995) found that approximately 30% of the fine roots of the plants growing in the Mussununga area were present in the litter standing stock, however this was not observed in the Mata Alta. The presence of fine roots (78-94% of total) in the topsoil (0.00-0.05 cm) in tropical forests (Rosado et al, 2011) represents an important mechanism linked to the optimization of nutrient absorption through direct absorption from decomposing litter. This ecological mechanism minimizes nutrient losses through leaching, especially in nutrient-poor sandy soils, thus favoring their retention in the ecosystem.…”

“…Among the root systems of mangroves, fine roots (roots < 2mm of diameter; Rosado et al 2011) play an important function in nutrient cycling because they make a great contribution to the dynamics of belowground phytomass. Fine roots are directly related to soil respiration, mycorrhiza activities and water and nutrient absorption, especially phosphorous (Kummerow et al 1990).…”
