Knowledge of spatial patterns and interactions of tree species allows for understanding the ecological
processes of spatiotemporal structures of tropical forests, becoming essential for the establishment of strategies
for the conservation and management of their resources in the long term. The aim of this study was to investigate
the spatial patterns and interactions of Astronium lecointei, Dinizia excelsa and Peltogyne paniculata, three
dominant timber tree species in the Jamari National Forest, Rondônia, Brazilian Amazon. The Kernel estimator
was used aiming to verify the possible influence of first-order factors on species distributions. Inhomogeneous
K-functions were applied to analyze species spatial patterns and interactions by means of second-order factors.
Univariate analyses revealed different scale-dependent spatial patterns for the species. Aggregation related to
ecological characteristics, such as habitat preference and dispersal limitation, was verified for A. lecointei and
P. paniculata. D. excelsa presented a random spatial pattern, explained by specific features of its establishment,
such as the need for clearings due to light requirements. Interspecific associations were evidenced by bivariate
analyses, in which spatial attraction of species resulted from the same preference for microhabitats and the repulsion
was a result of niche segregation. |
