Characterisation of 14 blue crane Grus paradisea (Gruidae,AVES) microsatellite loci for use in detecting illegal trade

Forty-two unique microsatellite loci were isolated from an unenriched and a tetranucleotide-enriched blue crane (Grus paradisea) genomic library. Fourteen polymorphic loci were characterised in 20 unrelated wild blue crane individuals from the Karoo region, South Africa, and displayed 4–27 alleles with observed heterozygosities ranging between 0.50 and 0.95. All 14 loci were also polymorphic in the grey-crowned crane (Balearica regulorum) and the wattled crane (Grus carunculatus). These markers are aimed at assisting the identification of illegal trade in the blue crane but have wider population and conservation applications for most, if not all, crane species.
