title: Spacing patterns and crown size variability in an Ecuadorian desert shrub species.
abstract: Analysis of spacing patterns in a monospecific stand of Croton menthodarus Benth. (Euphorbiaceae) suggests the presence of intraspecific competition. Analysis of the coefficient of variation for crown diameters suggests that increased plant density results in mortality of smallest individuals.
