We present three dinucleotide and six tetranucleotide microsatellite loci that were developed for the Brazilian free-tailed bat, Tadarida brasiliensis (Chiroptera, Molossidae). Ninety-one individuals from two populations were scored at each locus, revealing extremely high levels of polymorphism (15 –55 alleles per locus). These loci provide genetic markers for studying gene flow, migration and mating behaviour.

Incomplete lineage sorting can genetically link populations long after they have diverged, and will exert a more powerful influence on larger populations. The effects of this stochastic process can easily be confounded with those of gene flow, potentially leading to inaccurate estimates of dispersal capabilities or erroneous designation of evolutionarily significant units (ESUs). We have used phylogenetic, population genetic, and coalescent methods to examine genetic structuring in large populations of a widely dispersing bat species and to test hypotheses concerning the influences of coalescent stochasticity vs. gene flow. The Mexican free-tailed bat, Tadarida brasiliensis mexicana, exhibits variation in both migra- …
