Dispersal is a driving factor in the creation and maintenance of
biodiversity, yet little is known about the effects of habitat variation
and geography on dispersal and population connectivity in most mammalian
groups. Bats of the family Molossidae are fast-flying mammals thought to
have potentially high dispersal ability, and recent studies have indicated
gene flow across hundreds of kilometers in continental North American
populations of the Brazilian free-tailed bat, Tadarida brasiliensis. We
examined the population genetics, phylogeography, and morphology of this
species in Florida and across islands of The Bahamas, which are part of an
island archipelago in the West Indies. Previous studies indicate that bats
in the family Phyllostomidae, which are possibly less mobile than members
of the family Molossidae, exhibit population structuring across The
Bahamas. We hypothesized that T. brasiliensis would show high population
connectivity throughout the islands and that T. brasiliensis would show
higher connectivity than two species of phyllostomid bats that have been
previously examined in The Bahamas. Contrary to our predictions, T.
brasiliensis shows high population structure between two groups of islands
in The Bahamas, similar to the structure exhibited by one species of
phyllostomid bat. Phylogenetic and morphological analyses suggest that
this structure may be the result of ancient divergence between two
populations of T. brasiliensis that subsequently came into contact in The
Bahamas. Our findings additionally suggest that there may be cryptic
species within T. brasiliensis in The Bahamas and the West Indies more
broadly.
Skull and Forearm Measurements of Florida and Bahamas Tadarida
brasiliensisThis is a file of the raw data and averages for each skull
measurement and the forearm measurement used in this paper. The Individual
IDs are the Florida Museum of Natural History catalogue numbers. The
measurements are a subset of those used in Freeman (1981) and are labelled
based on the number labels provided in Freeman
(1981).TadaridaMeasurements_Dryad.csvMicrosatellite Allele CallsThe allele
calls are provided in the input format for Migrate-n. The first line
indicates the number of populations (2) and the number of loci used (9).
The second line provides the repeat length for each locus. The third lines
begins the information for population 1, which is the Little Bahama Bank
& Florida individuals (56 individuals sampled). The first 10
spaces of each line following the 3rd line (until the 2nd population is
reached) is the locality from which the individuals was collected, the
Florida Museum of Natural History catalogue number, and the sex. The
spaces immediately following the first 10 spaces begin the allele call
information. The allele calls for a single individual at a single locus
are separated by a period. Missing data is indicated by a question
mark.AlleleCalls_Dryad.txt
