Data from: Phylogeography of the dark fruit-eating bat Artibeus obscurus in the Brazilian Amazon
Artibeus obscurus (Mammalia: Chiroptera) is endemic to South America, being found in at least 18 Brazilian states. Recent studies revealed that different populations of this genus present distinct phylogeographic patterns; however, very little is known on the population genetics structure of A. obscurus in the Amazon rainforest. Here, using a fragment (1010bp) of the mitochondrial gene cytochrome b from 87 samples, we investigated patterns of genetic divergence among populations of A. obscurus from different locations in the Brazilian Amazon rainforest and compared them with other Brazilian and South American regions. Analysis of molecular variance (AMOVA), fixation index (Fst) analysis, and phylogeographic patterns showed divergence between two major monophyletic groups, each one corresponding to a geographic region associated with the Atlantic and Amazon forest biomes. The Atlantic forest clusters formed a monophyletic group with a high bootstrap support and a fragmented distribution that follows the pattern predicted by the Refuge Theory. On the other hand, a different scenario was observed for the Amazon forest, where no fragmentation was identified. The AMOVA results revealed a significant geographic heterogeneity in the distribution of genetic variation, with 70% found within populations across the studied populations (Fst values ranging from 0.05864 to 0.09673; φST = 0.55). The intrapopulational analysis revealed that one population (Bragança) showed significant evidence of population expansion, with the formation of 2 distinct phylogroups, suggesting the occurrence of a subspecies or at least a different population in this region. These results also suggest considerable heterogeneity for A. obscurus in the Amazon region.

FIGURE 3. Map of the distribution of Artibeus aequatorialis. Star indicates the type locality of A. aequatorialis (Zaruma [3°40'60"S, 79°37'0"W], Ecuador). The distributional range is based on literature references (hollow squares; Andersen 1906 and Marques-Aguiar 2008) and specimens examined in the Species Account (star and solid squares). The northernmost (western Colombia; Valle del Cauca, Cali [3°26'14"N, 76°31'21"W], and Rio Raposo [3°43'0"N, 77°7'60"W]) and southernmost (western Peru; Tumbes, Faical [3°44'57"S, 80°45'2"W]) extent of A. aequatorialis remains to be defined. Shaded areas represent areas of the Andes Mountains higher than 1800 meters.

Data from: Rapid development and screening of microsatellite loci for Artibeus lituratus and their utility for six related species within Phyllostomidae
Microsatellites are often the marker of choice for population genetic studies at intermediate spatial and temporal scales. Developing large numbers of markers has traditionally been technically difficult and this has limited our ability to investigate evolutionary phenomena that emerge across short temporal scales. Moreover, few markers tend to successfully amplify across species boundaries. As rapid advancements in high-throughput sequencing make microsatellite development cost and time-effective, new avenues for evolutionary, population genetic, and chromosome linkage mapping research are emerging. We used a published PERL script and second-generation sequencing to rapidly and affordably develop microsatellite loci for a widespread phyllostomid bat, Artibeus lituratus, for which no markers were previously available. We used Roche FLX (Titanium) Genome Sequencing to randomly sequence ~101 Mb (255,065 unique reads) of genomic DNA for A. lituratus, within which we discovered 30100 microsatellite loci. We designed primers for 19395 loci that contained suitable flanking regions. We ordered primers for 96 loci, 90 of which produced a single PCR product in A. lituratus. We genotyped 52 loci, and 45 were polymorphic in A. lituratus. We tested cross-species amplification for 96 loci in six additional phyllostomid species: A. planirostris, A. fimbriatus, A. phaeotis, Enchisthenes hartii, Sturnira lilium, and Carollia perspicillata. Cross-species amplification was successful for at least one species for 87 loci (A. fimbriatus), and in all species at least 66 loci amplified. These markers will facilitate future work on these seven species, but also illustrate the utility of this high-throughput method for development of primers across many species simultaneously.
3D models of Artibeus jamaicensis and Rhinolophus pusillus hyoid apparatus and tympanic bones
<p>The morphology of the stylohyal-tympanic bone articulation found in laryngeally echolocating 7 bats is highly indicative of a function associated with signal production. One untested hypothesis is that 8 this morphology allows the transfer of a sound signal from the larynx to the tympanic bones (auditory 9 bulla) via the hyoid apparatus during signal production by the larynx. We used µCT data and finite 10 element analysis (FEA) to model the propagation of sound through the hyoid chain into the tympanic 11 bones to test this hypothesis. We modeled sound pressure (dB) wave propagation from the basihyal to the 12 tympanic bones, vibratory behavior (m) of the stylohyal – tympanic bone unit, and the stylohyal and 13 tympanic bones when the stylohyal bone is allowed to pivot on the tympanic bone. Sound pressure wave 14 propagation was modeled using the harmonic acoustics solver in ANSYS and vibratory behavior was 15 modeled using coupled modal and harmonic response analyses in ANSYS. For both analyses (harmonic 16 acoustics and harmonic response), the input excitation on the basihyal and thyrohyals was modeled as the 17 estimated pressure (Pa) imposed by the collision of the vibrating thyroid cartilage of the larynx against 18 these bones during signal production. Our models support the hypothesis that this stereotypical hyoid 19 morphology found in laryngeally echolocating bats can transfer sound to the auditory bullae at an 20 amplitude that is likely heard for the species Artibeus jamaicensis and Rhinolophus pusillus</p>
