Nutrient fluxes in litterfall of a secondary successional alluvial rain forest in Southern Brazil.
During forest succession, litterfall nutrient fluxes increase significantly. The higher inputs of organic matter and nutrients through litterfall affects positively soil fertility and the species composition, which are essential components in forest restoration and management programs. In the present study, the input of nutrients to the forest soil via litterfall components was estimated for tw...
متن کاملChanges in Forest Soil Properties in Different Successional Stages in Lower Tropical China
BACKGROUND Natural forest succession often affects soil physical and chemical properties. Selected physical and chemical soil properties were studied in an old-growth forest across a forest successional series in Dinghushan Nature Reserve, Southern China. METHODOLOGY/PRINCIPAL FINDINGS The aim was to assess the effects of forest succession change on soil properties. Soil samples (0-20 cm dept...
متن کاملSensitivity of understorey bird species in two different successional stages of the lowland Atlantic Forest, Brazil.
The Atlantic Forest has a high destruction rate and there is little information available on some aspects of the neotropical bird biology. Changes in environment are important factors that affect the resources available to birds. We compared the species sensitivity level of understorey birds in two areas in distinct successional stages (primary and secondary sections). Two 100 ha plots of lowla...
متن کامل[Anopheles cruzii parity in dense rain forest in Southern Brazil].
OBJECTIVE To determine the parity and ovarian development of Anopheles cruzii species during the seasons. METHODS Collections were carried out fortnightly in the morning in the Palmito State Park in the municipality of Paranaguá, Southern Brazil, between April 2004 and April 2005. Adult mosquitoes were captured using human landing rate. Dissections were performed using Detinova's and Polovodo...
متن کاملForest structure and species composition along a successional gradient of Lowland Atlantic Forest in Southern Brazil
The Lowland Forest is one of the most disturbed and fragile ecosystems in the Atlantic Forest biome, yet little is known regarding its successional trajectory and resilience. We evaluated changes in species assemblages and forest structure of the canopy and understory along a successional gradient (young 21-yrs old forest, immature 34-yrs old forest and late successional 59-yrs old forest) aimi...
