Development of a SNP Panel for Geographic Assignment and Population Monitoring of Jaguars (Panthera onca)

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
We have developed a genome‐enabled single nucleotide polymorphism (SNP) panel for use in jaguar geographic traceability, individual identification, kinship, and sexing. Our panel, named “Jag‐SNP”, comprises 459 SNPs selected from an initial pool of 13,373,949 markers based on the inter‐biome FST, followed by rigorous filtering and addition of eight sex‐
