Aislamiento y caracterización de loci de microsatelites en el charal de Xochimilco Chirostoma humboldtianum

Researchers have identified and characterized eight polymorphic microsatellite loci for the endangered Chirostoma humboldtianum, also known as charal de Xochimilco, a fish species endemic to Mexico's UNESCO-listed Historic Centre of Mexico City and Xochimilco. These genetic markers, derived from an enriched gene library, reveal significant deviations from Hardy-Weinberg equilibrium, likely due to small population sizes and habitat loss caused by human disturbances. The loci exhibit high observed (0.61) and expected (0.63) heterozygosity, with allele counts ranging from 3 to 11 per locus. This study represents the first description of microsatellite markers for this species and its genus, offering valuable tools for population genetics research, conservation efforts, and sustainable management strategies.
