Book Description
The aims of this work were to estimate the total accumulation of elemental carbon (Celem) and equivalent (CO2), and the species diversity in three physiognomies of the Atlantic Rainforest: Semideciduous Seasonal Forest (SSF), Riparian Forest (RF) and u201cCerradu00e3ou201d (CE). All five carbon sinks proposed by the IPCC were measured: tree biomass (DBH u2265 5 cm), dead wood, root biomass, litter and soil (every 20 cm up to 1 m depth). An analysis of variance (ANOVA) was performed to compare Celem and CO2 accumulation in the vegetations and the diversity index of Shannon (H') was calculated. ANOVA indicated that Celem and CO2 in the Riparian Forest and Cerradu00e3o present a significant difference. Celem average in RF was 385.89 u00b1 50.59 Mg ha-1, in SSF it was 350.97 u00b1 27.71 Mg ha-1 and 212.79 u00b1 39.19 Mg ha-1 in CE. The CO2 average reached 1416.22 u00b1 185.67 Mg ha-1 in RF, in SSF it ranked 1288.07 u00b1 101.69 Mg ha-1 and 780.95 u00b1 143.82 Mg ha-1 in CE. In all three physiognomies the Celem and CO2 distribution in the sinks was on average 40% in trees, 52% in the soil, 5% in roots, 1% in the litter and 2% in dead wood. The species diversity was the like in the three vegetation formations: RF (H' = 3.42), SSF (H' = 3.66) and CE (H' = 3.70). Forests can have different amounts of carbon and equal species diversity, and therefore, carbon and diversity require explicit considerations in environmental policies.
