“…In fact, all three lineages of Pteronotus bats in the Antilles are thought to be of continental origin (11). However, congruent with the suggestion of Dávalos (11,12) that Caribbean islands act both as sources and sinks for bat colonists, mainland bat flies in the N. coxata group (and their symbionts) likely have a Caribbean origin ( Fig. 2A, clades C and D).…”

We investigated previously unknown associations between bacterial endosymbionts and bat flies of the subfamily Nycterophiliinae (Diptera, Streblidae). Molecular analyses revealed a novel clade of Gammaproteobacteria in Nycterophilia bat flies. This clade was not closely related to Arsenophonus-like microbes found in its sister genus Phalconomus and other bat flies. High population infection rates in Nycterophilia across a wide geographic area, the presence of the symbionts in pupae, the general codivergence between hosts and symbionts, and high AT composition bias in symbiont genes together suggest that this host-symbiont association is obligate in nature and ancient in origin. Some Nycterophilia samples (14.8%) also contained Wolbachia supergroup F (Alphaproteobacteria), suggesting a facultative symbiosis. Likelihood-based ancestral character mapping revealed that, initially, obligate symbionts exhibited association with host-specific Nycterophilia bat flies that use a broad temperature range of cave environments for pupal development. As this mutualism evolved, the temperature range of bat flies narrowed to an exclusive use of hot caves, which was followed by a secondary broadening of the bat flies' host associations. These results suggest that the symbiosis has influenced the environmental tolerance of parasite life history stages. Furthermore, the contingent change to an expanded host range of Nycterophilia bat flies upon narrowing the ecological niche of their developmental stages suggests that altered environmental tolerance across life history stages may be a crucial factor in shaping parasite-host relationships.

“…Introgression has been used to explain conflict between mitochondrial haplotype diversity and coalescent pattern and either morphologically delineated evolutionary units, or phylogenies based on nuclear data (e.g. Dávalos, 2005; Russell et al , 2008). More extensive analyses with dense population samples from more than two independent loci have uncovered patterns of genetic diversity and differentiation consistent with female- (Berthier, Excoffier & Ruedi, 2006), or male-mediated introgression (Mao et al , 2010).…”

Understanding phylogenetic incongruence: lessons from phyllostomid bats

All characters and trait systems in an organism share a common evolutionary history that can be estimated using phylogenetic methods. However, differential rates of change and the evolutionary mechanisms driving those rates result in pervasive phylogenetic conflict. These drivers need to be uncovered because mismatches between evolutionary processes and phylogenetic models can lead to high confidence in incorrect hypotheses. Incongruence between phylogenies derived from morphological versus molecular analyses, and between trees based on different subsets of molecular sequences has become pervasive as datasets have expanded rapidly in both characters and species. For more than a decade, evolutionary relationships among members of the New World bat family Phyllostomidae inferred from morphological and molecular data have been in conflict. Here, we develop and apply methods to minimize systematic biases, uncover the biological mechanisms underlying phylogenetic conflict, and outline data requirements for future phylogenomic and morphological data collection. We introduce new morphological data for phyllostomids and outgroups and expand previous molecular analyses to eliminate methodological sources of phylogenetic conflict such as taxonomic sampling, sparse character sampling, or use of different algorithms to estimate the phylogeny. We also evaluate the impact of biological sources of conflict: saturation in morphological changes and molecular substitutions, and other processes that result in incongruent trees, including convergent morphological and molecular evolution. Methodological sources of incongruence play some role in generating phylogenetic conflict, and are relatively easy to eliminate by matching taxa, collecting more characters, and applying the same algorithms to optimize phylogeny. The evolutionary patterns uncovered are consistent with multiple biological sources of conflict, including saturation in morphological and molecular changes, adaptive morphological convergence among nectar-feeding lineages, and incongruent gene trees. Applying methods to account for nucleotide sequence saturation reduces, but does not completely eliminate, phylogenetic conflict. We ruled out paralogy, lateral gene transfer, and poor taxon sampling and outgroup choices among the processes leading to incongruent gene trees in phyllostomid bats. Uncovering and countering the possible effects of introgression and lineage sorting of ancestral polymorphism on gene trees will require great leaps in genomic and allelic sequencing in this species-rich mammalian family. We also found evidence for adaptive molecular evolution leading to convergence in mitochondrial proteins among nectar-feeding lineages. In conclusion, the biological processes that generate phylogenetic conflict are ubiquitous, and overcoming incongruence requires better models and more data than have been collected even in well-studied organisms such as phyllostomid bats.

“…Therefore, our results indicate that the invasion of the Grenadines may have occurred posteriorly, by a South American population of N. leporinus . This pattern is similar to that proposed for another bat species, Natalus stramineus Gray, 1838 (Dávalos, ). Our data also indicate that the Caribbean islands (Montserrat and probably Greater Antilles), together with Mexico and Central America, seem to harbour the ancestry of the piscivore lineage.…”

We present phylogenetic relationships and phylogeographic patterns of the two species of bulldog bats, genus Noctilio. Using a comprehensive sampling of 118 individuals throughout the species distribution, we investigated the distribution of molecular variation in one nuclear and two mitochondrial markers. Phylogenetic trees do not recover Noctilio albiventris as a monophyletic group and point to three similar‐age intraspecific genetic lineages, suggesting cryptic diversity in this taxon. These lineages correspond to the subspecies previously proposed, and are strongly associated with major river basins in South America. Analyses also suggest a very recent origin for the fishing bat Noctilio leporinus, which probably originates from N. albiventris, with a population expansion corresponding to its invasion in South America. Based on our analysis, the speciation event was dated in the Pleistocene epoch and seems to be associated with the variation of the sea level in the Caribbean islands. The present work indicates how phylogeographic studies support the identification of independent evolutionary lineages, driving new systematic/taxonomic investigations, while at the same time shed light on the role of the Caribbean in shaping Neotropical bat fauna diversity. © 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, ••, ••–••.
