Litter production in a natural stand of Brazil nut trees (Bertholletia excelsa Bonpl.). Repositório Alice
GUERREIRO, Q. L. de M.; OLIVEIRA JUNIOR, R. C. de; RUIVO, M. de L. P.; SILVA, K. E. da; BELDINI, T. P.; GUEDES, M. C.; MOTA, A. F. L.; MORAES, B. L. T. de; SANTOS, P. R. B.; DUIN, I. M..
This research estimated litter production and analyzed its relation to environmental variables such as maximum temperature, insolation, and rainfall. The study was conducted on a 300 × 300 m experiment as part of the project titled mapping of native Brazil nut stands and socio-environmental and economic characterization of Brazil nut production systems (MapCast), in the Tapajós National Forest (FLONA Tapajós). Every 30 days for one full year (August 2015 to July 2016), litterfall was collected and stored in a laboratory. After drying, the material was separated into leaves, wood, flowers and fruits, and miscellaneous and weighed. Statistical tests conducted were Shapiro-Wilk (5%), Principal coordinate analysis, t-test, Pearson?s linear correlation,...

Spatial variability of soil physical and chemical aspects in a Brazil nut tree stand in the Brazilian Amazon. Repositório Alice
GUERREIRO, Q. L. de M.; OLIVEIRA JUNIOR, R. C. de; SANTOS, G. R. dos; RUIVO, M. de L. P.; BELDINI, T. P.; CARVALHO, E. J. M.; SILVA, K. E. da; GUEDES, M. C.; SANTOS, P. R. B..
The Brazil nut is considered one of the noblest trees of the Amazon biome and contains social, ecologic and economic importance to this region. The study of the spatial variance of the edaphic properties in native nut trees can direct future researches about more efficient samplings. The Geostatistics is the methodology utilized for this type of study, once that it considers the structural and random characteristics of a variable spatially distributed. This work sought to get a higher knowledge about the distribution of the nutrients in the soil, verifying the relationship with the occurrence of this species, to thereby provide subsidies to future forest management and maintenance/enlargement of the productivity in these areas. The soil samples were...
