ABSTRACT Forest cover in areas degraded by mining is an alternative way of mitigating CO2 concentrations in the atmosphere by fixing C in tree biomass. This study evaluated the growth and C stocks of forest cover in an area of bauxite mining with four sources of fertilizer. Height (Ht), diameter at ground level (DGL), and diameter at breast height (DBH) were determined in Anadenanthera peregrina (Ap), clonal Eucalyptus (Euc), and a mixed plantation of 16 native forest species (Nat) at 6, 18, 36, and 56 months of age. Trunk+bark volume, biomass, and C stock were also determined for these forest covers at 56 months of age. The fertilization treatments were a standard (SF) adopted by the company, SF plus organic fertilizer (OF), chemical fertilizer (CF), and... |

Atta cephalotes (L.) presents a wide distribution in the Neotropical region. In Brazil, this species is disjunctly distributed in the Amazon region and in the states of Maranhão, Pernambuco and southern Bahia, all of which belong to Northeast Region. Here we report on a survey of Atta colonies in 42 remnants of the Atlantic rainforest in Alagoas and Pernambuco. Our results include new records of A. cephalotes in the state of Alagoas and thereby extend the known distribution area of its southern populations in Northeast Brazil. In addition, the species was strongly associated with well-conserved forest remnants, indicating that it is highly sensitive to disturbance. We suggest that, in the fragmented scenario of the northeastern Atlantic forest, A.... |
