Leptonycteris yerbabuenae is a nectarivore (subfamily: Glossophaginae, family: Phyllostomidae), is found from southern Arizona/southwestern New Mexico to southern Mexico including the Baja California peninsula (Ceballos et al.1997; Cockrum 1991).
Leptonycteris yerbabuenae is listed as endangered in the United States (Shull 1988) and threatened in Mexico (SEMARNAT 2002). They migrate up to 1,800 km between wintering and breeding grounds (Fleming and Eby 2001). Females mate in the winter in southern Mexico, and migrate to maternity roosts in northern Mexico/southern Arizona to give birth in late spring-early summer (Ceballos et al.1997; Cockrum 1991). Wilkinson and Fleming (1996) have suggested two separate migration corridors where bats occupy southeastern Arizona and southwestern Arizona arrive and leave through separate corridors. We isolated 12 microsatellites loci to estimate gene flow between southwestern and southeastern Arizona roosts, as well as Sonora, Baja California, and Jalisco, Mexico.
Genomic DNA was extracted using the DNeasy Blood & Tissue Kit (Qiagen). Approximately 5 μg of genomic DNA was digested with RsaI (NEB) and fragments were ligated to double-stranded SuperSNX-24 linkers to construct an enriched genomic DNA library using a modified version of Glenn and Schable (2005). Linker-ligated fragments ranging from 300–1400 bp were recovered using the polymerase chain reaction (PCR) with a SuperSNX-24 forward primer and Platinum high-fidelity Taq DNA polymerase (Invitrogen), and were hybridized to 5′-biotinylated microsatellite oligonucleotide probes (GT)15, (CT)15, (GATA)10 and (GACA)8. Hybridized fragments were captured on streptavidin-coated paramagnetic beads (Dynal) and then recovered by PCR. These fragments were ligated into the vector PCR4-TOPO (Invitrogen), and transformed into TOP10 chemically competent E. coli cells (Invitrogen) following the manufacturer’s protocol.
