Abstract
The objectives of this study were: to examine,
characterize and interpret the spatial pattern of Tornillo (Cedrelinga cateniformis)
and Guabilla (Inga sp.) And to analyze their relationship with some spatial
covariates in the Amazon region, Peru. The statistical analysis was carried out
through the tools of the analysis of spatial point patterns, which provide a set of
methods, which based on the georeferenced location of the species allowed to
estimate: the intensity of points, the function K (r) and L (r) and perform hypothesis
tests of the underlying point process in the study area. Likewise, from the
formulation of models, the relationships with a set of spatial covariates were
evaluated. The methods used show a non-homogeneous spatial pattern of all the
Tornillo and Guabilla trees present in the study areas, clearly perceiving the
aggregation of points at short distances (approximately 15 meters) and significant
in the entire range studied. Also, it was determined that the intensity of Guabilla is
related to the distance to the seedbed, while the Tornillo is also related to the
altitude above sea level and the distance to the rivers, which could be seen in at
least one of the four study areas.
