Isolation and characterization of microsatellite markers from the chestnut‐backed antbird, Myrmeciza exsul

We describe nine microsatellite loci from the chestnut-backed antbird (Myrmeciza exsul), and one locus from the spotted antbird (Hylophylax naevioides) that cross-amplifies in chestnut-backed antbirds. The chestnut-backed antbird is a common understorey insectivore in Neotropical lowland rain forests ranging from eastern Nicaragua to western Ecuador. Primers were developed in order to assess population structure in a fragmented landscape and to study dispersal at a local scale. Primers were tested on 60–62 individuals from a single population in the Sarapiqui Province of Costa Rica. Loci had varying degrees of polymorphism, ranging from two to 19 alleles.
