Litter deposition as bioindicator of restoration in a dense revegetation system
Machado, Murilo Rezende; Rodrigues, Fátima C.M.Piña; Pereira, Marcos GervásioLitter deposition pattern was applied as bioindicator to compare sites at different successional stages with a dense restoration plantation. Litter traps (0.25 m2) were used and a production of 10.17 Mg ha-1 year-1 was obtained for secondary forest similar to a medium sector in the restoration area (8.98 Mg ha-1 year-1). Lower (5.85 Mg ha-1 year-1), upper (5.81 Mg ha-1 year -1), and bush (5.63 Mg ha-1 year-1) l...
Silvicultural performance of five forest species in the central Brazilian Amazon
Machado, Murilo Rezende; Camara, Rodrigo; Sampaio, Paulo de Tarso Barbosa; Ferraz, João Baptista Silva; Pereira, Marcos GervásioPlantios de espécies florestais de interesse madeireiro contribuem para diminuir a pressão sobre a floresta amazônica, proporcionam o desenvolvimento sustentável na região e geram benefícios ecológicos. Este estudo objetivou avaliar a sobrevivência e o crescimento de quatro espécies nativas (Swietenia macrophylla, Parkia decussata, Dipteryx odorata e Jacaranda copaia) e uma exótica (Acacia mangium), em plantios...
Different patterns of nutrient cycling in contiguous phytophysiognomies of Atla...
Menezes, Luís Fernando Tavares de; Souza, Rodrigo Camara de; Pereira, Marcos Gervásio; Pires, Fábio Ribeiro; Fanticelle, Bruno SantannaThe present study aimed to evaluate fine aboveground litterfall, deposition of nitrogen and phosphorus from total litterfall and leaf litter decomposition in areas of tall forest (Mata Alta) and low forest on sandy soils (Mussununga) in southeastern Brazil. Fine litterfall was collected monthly for two years (from June/2007 to May/2009) in 10 conical collectors (0.25 m2) in each phytophysiognomy (1 ha plots). T...
Land cover changes affect soil chemical attributes in the Brazilian Amazon
Machado, Murilo Rezende; Camara, Rodrigo; Sampaio, Paulo de Tarso Barbosa; Pereira, Marcos Gervásio; Ferraz, João Baptista SilvaForest plantations may minimize the effects of deforestation in the Amazon. However, there are differences among species in terms of their influences on soil recovery. The effects of monospecific plantations of Acacia mangium, Dipteryx odorata, Jacaranda copaia, Parkia decussata,and Swietenia macrophylla, and areas of pasture and native forest on the chemical soil attributes of the Brazilian Amazon were evaluat...
Floristics and phytosociology in areas of dense woodland and mesophytic forest ...
Giácomo, Rômulo Guimarães; Pereira, Marcos Gervásio; Carvalho, Daniel Costa de; Medeiros, Victor Satiro de; Gaui, Tatiana DiasThe objective of this study was to evaluate the floristic and phytosociological parameters of the species present in areas of mesophytic forest and dense woodland in the Pirapitinga Ecological Station, Minas Gerais state, Brazil. For the survey of floristic and phytosociological parameters, a total of 108 plots of 100 m2 were implanted, where all individuals with circumference at ground height (CGH) ≥ 16 cm wer...
Litter production and nutrient addition in atlantic forest areas in Santa Maria...
Calvi, Geangelo Petene; Pereira, Marcos Gervásio; Espíndula Júnior, AdemarThis study was accomplished on Espíndula Farm, Santa Maria de Jetibá (ES), with the objective of evaluating the litter and nutrients deposition in areas with different succession stadiums. Two areas were selected with different vegetable coverings, defined as: (SF) Secondary Forest, with about 25 ha of area, corresponding to an old area of cassava cultivation with about 50 years in process of ecological success...
Phytosociology of native species in the understory of a corymbia citriodora sta...
Carvalho, Daniel Costa de; Gaui, Tatiana Dias; Pereira, Marcos Gervásio; Simon, Cátia Aparecida; Toledo, Luciano Oliveira; Nettesheim, Felipe CitoThis study is based on the hypothesis that unmanaged plantations of commercial species do not prevent understory colonization by native species. The research aimed to describe the floristic composition and structure of native arboreal species in the understory of a Corymbia citriodora stand. To this end, 112 plots (10 × 10 m; 1.12 ha) were installed. Six hundred native tree individuals distributed in 54 species...
Nutrient retranslocation in forest species in the brazilian amazon
Machado, Murilo Rezende; Sampaio, Paulo de Tarso Barbosa; Ferraz, João Baptista Silva; Camara, Rodrigo; Pereira, Marcos GervásioInternal retranslocation is an important mechanism for nutrient conservation in plants, which depends on different factors. However, there are little data about this subject, especially on tropical forest species. This study aimed to evaluate the macronutrient retranslocation dynamic and the influence of ecological (P: pioneer x NP: non-pioneer) and phenological (ND: non-deciduous x D: semideciduous/deciduous) ...
Changes in past global solar radiation based on climate models and remote sensi...
de Jesus, Carolina Souza Leite; Delgado, Rafael Coll; Pereira, Marcos Gervásio; Souza, Leonardo Paula de; Silva Junior, Carlos Antonio daThe objective of this study was to perform a temporal and spatial analysis of the changes in the past global solar radiation based on climate models and remote sensing data in the State of Rio de Janeiro, Brazil for the baseline period (1961-1990). Data from two climate models - the Canadian Centre for Climate Modelling and Analysis and Geophysical Fluid Dynamic Laboratory, were used for the A1B intermediate sc...
