Flora of Baturité, Ceará: a Wet Island in the Brazilian Semiarid
Silvera,Andréa Pereira; Loiola,Maria Iracema Bezerra; Gomes,Vaneicia dos Santos; Lima-Verde,Luiz Wilson; Oliveira,Teógenes Senna; Silva,Edison FernandesAbstract The biota of the humid mountain ranges of the Brazilian semiarid is still poorly understood. In order to fill this scientific gap, we carried out an extensive survey along altitudinal ranges (400m - 1,000 m) on both the windward and the leeward slopes of the Baturité Mountain Range, in the state of Ceará state. We registered 400 plant species and 92 families. The Myrtaceae (36 spp.), Fabaceae (25 spp.)...
Growth, Biomass and Carbon Stocks in Forest Cover Planted in an Area of Bauxite...
Valente,Fernanda Daniele de Almeida; Castro,Marllon Fialho de; Torres,Carlos Moreira Miquelino Eleto; Neves,Júlio César Lima; Silva,Ivo RibeiroABSTRACT 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 Eu...
Carbon sequestration and nutrient reserves under differen t land use systems
Aguiar,Maria Ivanilda; Fialho,Jamili Silva; Campanha,Mônica Matoso; Oliveira,Teógenes SennaThis study evaluated the contribution of agroforestry (AFS) and traditional systems to carbon sequestration and nutrient reserves in plants, litter and soil. The study was carried out in the semiarid region of Brazil in a long-term experiment on an experimental farm of the goat and sheep section of the Brazilian Agricultural Research Corporation (Embrapa). Two agroforestry systems were investigated: agrosilvopa...
