Anthropogenic disturbances stimulate natural regeneration of Euxylophora paraen...
Duarte, Joyce Ananda Paixão; Silva, José Natalino Macedo; Pires, Jakeline Prata de Assis; Ferreira, Gracialda Costa; Dionisio, Luiz Fernandes SilvaIn the Brazilian Amazon, forest fragments increase annually leading many species to local extinction. Euxylophora paraensis Huber is an endemic species whose natural habitat is restricted to the north of Brazil. The natural regeneration was evaluated using 10 circular plots of land each with a radius of 20 meters. The density of regenerating individuals at the edge and the interior of the fragment and the behav...

Litterfall, litter stock and water holding capacity in post-mining forest resto...
Martins, Walter Bruno Rocha; Lobo do Vale, Raquel; Ferreira, Gracialda Costa; Andrade, Vanda Maria Sales; Dionísio, Luiz Fernandes SilvaThe objective of this study was to evaluate the litterfall deposition, the decomposition rate (KL) and the water holding capacity (WHC) of litter stored in the soil in two areas degraded by mining submitted to different methods of forest restoration: induction of natural regeneration (NR) and planting seedlings of native forest species (PS) with a forest fragment (FF) used as reference. The litterfall depositio...
