Randomized trial reveals genetic diversity in Agave karwinskii, suggesting management practices enhance conservation strategies.

The aim is to understand how management practices and geographical distribution shape the genetic structure of Agave karwinskii.
Generated genomic data using RADseq
Conducted population-level analyses integrating biological and management contexts
Evaluated genetic diversity and management indicators relevant to the Global Biodiversity Framework.
Agave karwinskii exhibited high genetic diversity (Hs = 0.25) and moderate population differentiation (FST = 0.19)
Identified 173 SNPs as candidate loci associated with environmental adaptation
Ne declined sharply in clonal and semi-cultivated systems, affecting conservation thresholds.

Martínez-Velasco et al. (2026) studied this question.
