Primers for novel microsatellite markers in “fire-specialist” lizards (Amphibolurus norrisi, Ctenotus atlas and Nephrurus stellatus) and their performance across multiple populations

We developed 45 microsatellite markers for three lizard species with fire-related distributions: Amphibolurus norrisi, Ctenotus atlas and Nephrurus stellatus (17, 12 and 16 markers respectively). To isolate microsatellites we used an enrichment technique for N. stellatus and next-generation sequencing for A. norrisi and C. atlas. Fluorescent tags were attached to primers during PCR for flexible genotyping. All loci were polymorphic with 2–24 alleles and expected heterozygosities of 0.043–0.927. These markers will facilitate studies of post-fire dispersal and recolonisation.
