Cryptic spatial aggregation of the cushion plant Azorella selago (Apiaceae) revealed by a multilocus molecular approach suggests frequent intraspecific facilitation under sub-Antarctic conditions.

Abstract excerpt

PREMISE OF THE STUDY: In abiotically severe habitats, intraspecific aggregations can increase species' fitness by ameliorating stressful environmental factors. However, the difficulty of identifying individual plants in some growth forms makes the measurements of intraspecific aggregation, and therefore the assessment of intraspecific facilitation, problematic. In this study, we examined the genotype composition...
