Effects of silvicultural treatments on temporal variations of spatial autocorrelation in Eucalyptus plantations in Brazil

摘要: Abstract We examined the change in spatial structures of Eucalyptus plantations across different types silvicultural treatments over a full rotation. Clonal and seed-origin plots applied with differing levels fertilization (high vs. traditional) irrigation (irrigated non-irrigated) were investigated. Additionally, for clonal plots, uniform heterogeneous stand structure created using staggered planting dates. The aimed to mimic plots. Spatial characterized by assessing autocorrelations diameters, heights, biomass. also two distance-based neighborhood look at degree numbers neighboring trees being defined as neighbors. results suggest that biomass mostly insignificant an alpha level 0.05 However, most after middle rotation predominantly negative, indicating occurrence size differences among trees. In particular, general declining patterns from positive negative diameters biomass, except structures, noted treated high fertilizer. This suggests may have influenced realizations microsite effects early stage development. General trends between considered similar several intensities
