Bat Systematics in the Light of Unconstrained Analyses of a Comprehensive Molecular Supermatrix
Journal of Mammalian Evolution, 2016
Bats (Chiroptera) represent the largest diversification of extant mammals after rodents. Here we report the results of a large-scale phylogeny of bats based on unconstrained searches for a data matrix of 804 non-chimeric, taxonomically updated bat terminals (796 species represented by a single terminal plus three species represented by ≥2 genetically distinct subspecies), able to preliminary test the systematics of most groups simultaneously. We used nine nuclear and mitochondrial DNA sequence markers fragmentary represented for ingroups (c. 90% and 64% of extant diversity at genus and species level, respectively) and 20 diverse placental outgroups. Maximum Likelihood and Parsimony analyses applied to the concatenated dataset yielded a highly resolved, variously supported phylogeny that recovered the majority of currently recognized clades at all levels of the chiropteran tree. Calibration points based on 44 key fossils allowed the Bayesian dating of bat origins at c. 4 my after the K-Pg boundary, and the determination of stem and crown ages of intraordinal clades. As expected, bats appeared nested in Laurasiatheria and split into Yinpterochiroptera and Yangochiroptera. More remarkable, all polytypic, currently recognized families were monophyletic, including Miniopteridae, Cistugidae, and Rhinonycteridae, as well as most polytypic genera with few expected exceptions (e.g., Hipposideros). The controversial Myzopodidae appeared in a novel position as sister of Emballonuroidea-a result with interesting biogeographic implications. Most recently recognized subfamilies, genera, and species groups were supported or only minor adjustments to the current taxonomy would be required, except Molossidae, which should be revised thoroughly. In light of our analysis, current bat systematics is strongly supported at all levels; the emergent perception of a strong biogeographic imprint on many recovered bat clades is emphasized.
Mitochondrial DNA Part B, 2020
The mitogenome of Eptesicus serotinus (Serotine bat) was published in 2013 with GenBank accession number KF111725 and NCBI Reference Sequence number NC_022474. This sequence was placed with Vespertilio sinensis (Asian parti-colored bat) in a COI gene tree but with Hypsugo alashanicus (Alashanian pipistrelle) in a cytochrome b gene tree. Direct comparison of mitogenomes showed that 92.4% of this mitogenome is similar to Vespertilio sinensis, 5.9% to Hypsugo alaschanicus, and that 1.6% of the mitogenome could not be attributed to either species, or any other species. This mitogenome has been re-used in at least 17 phylogenies. Our findings suggest that mitogenomes are best verified with multiple gene trees, followed by direct comparison of sequences. We conclude that greater vigilance is warranted to ensure that problematic sequences do not enter the scientific record, and are not re-used in subsequent studies.
A phylogenetic supertree of the bats (Mammalia: Chiroptera)
Biological Reviews, 2002
We present the first estimate of the phylogenetic relationships among all 916 extant and nine recently extinct species of bats (Mammalia : Chiroptera), a group that accounts for almost one-quarter of extant mammalian diversity. This phylogeny was derived by combining 105 estimates of bat phylogenetic relationships published since 1970 using the supertree construction technique of Matrix Representation with Parsimony (MRP). Despite the explosive growth in the number of phylogenetic studies of bats since 1990, phylogenetic relationships in the order have been studied non-randomly. For example, over one-third of all bat systematic studies to date have focused on relationships within Phyllostomidae, whereas relationships within clades such as Kerivoulinae and Murinae have never been studied using cladistic methods. Resolution in the supertree similarly differs among clades : overall resolution is poor (46.4 % of a fully bifurcating solution) but reaches 100 % in some groups (e.g. relationships within Mormoopidae). The supertree analysis does not support a recent proposal that Microchiroptera is paraphyletic with respect to Megachiroptera, as the majority of source topologies support microbat monophyly. Although it is not a substitute for comprehensive phylogenetic analyses of primary molecular and morphological data, the bat supertree provides a useful tool for future phylogenetic comparative and macroevolutionary studies. Additionally, it identifies clades that have been little studied, highlights groups within which relationships are controversial, and like all phylogenetic studies, provides preliminary hypotheses that can form starting points for future phylogenetic studies of bats.
Phylogenomic Analyses Elucidate the Evolutionary Relationships of Bats
Molecular phylogenetics has rapidly established the evolutionary positions of most major mammal groups , yet analyses have repeatedly failed to agree on that of bats (order Chiroptera) . Moreover, the relationship among the major bat lineages has proven equally contentious, with ongoing disagreements about whether echolocating bats are paraphyletic [7-9] or a true group [10] having profound implications for whether echolocation evolved once or possibly multiple times. By generating new bat genome data and applying model-based phylogenomic analyses designed to accommodate heterogeneous evolutionary processes , we show that-contrary to recent suggestions-bats are not closely related to odd-toed ungulates but instead have a more ancient origin as sister group to a large clade of carnivores, ungulates, and cetaceans. Additionally, we provide the first genome-scale support showing that laryngeal echolocating bats are not a true group and that this paraphyly is robust to their position within mammals. We suggest that earlier disagreements in the literature may reflect model misspecification, long-branch artifacts, poor taxonomic coverage, and differences in the phylogenetic markers used. These findings are a timely reminder of the relevance of experimental design and careful statistical analysis as we move into the phylogenomic era.

AimThere is an increasing evidence showing that species within various taxonomic groups have reticulate evolutionary histories with several cases of introgression events. Investigating the phylogeography of species complexes can provide insight into these introgressions, and when and where these hybridizations occurred. In this study, we investigate the biogeography of a widely distributed Western Palaearctic bat species complex, namely Myotis nattereri sensu lato. This complex exhibits high genetic diversity and in its western distribution range is composed of deeply diverged genetical lineages. However, little is known about the genetic structure of the eastern populations. We also infer the conservation and taxonomical implications of the identified genetic divergences.TaxonMyotis nattereri sensu lato including M. schaubi.LocationWestern Palaearctic.MethodsWe analysed 161 specimens collected from 67 locations and sequenced one mitochondrial and four nuclear DNA markers, and combi...

Using standard phylogenetic techniques, 25 transformation series of morphological characters and 11 of karyological characters are evaluated in an attempt to recover the phylogenetic history of plecotine vespertilionid bats. Plecotini contains four genera in the topology (Euderma (Barbastella (Plecotus Corynorhinus))). The Plecotini of Hill and Harrison (1987), including Rhogeessa, Baeodon, Nycticeius, and Otonycteris, is rejected because this view is based solely on subjective evaluations ofbacular overall similarity, and is clearly in disagreement with other lines of evidence from anatomy and karyology. Idionycteris is synonymized with Euderma because L phyllotis and E. maculatum are sister species. Corynorhinus is removed from the synonymy of Plecotus. The relationships within Corynorhinus and Plecotus are not resolved.

We examined the systematics of round-eared bats (Tonatia and Lophostoma) using sequence data from the nuclear recombination activator gene-2 (Rag2) gene and the mitochondrial valine transfer RNA, 12S ribosomal RNA (rRNA), and 16S rRNA. Some analyses of the mitochondrial and combined data sets indicate that round-eared bats may be paraphyletic relative to the genera Phyllostomus, Phylloderma, and Mimon. Both nuclear and mitochondrial data sets indicate substantial genetic divergence between Tonatia and Lophostoma, and neither data set unambiguously demonstrates monophyly of round-eared bats. However, our analyses cannot exclude the possibility that round-eared bats form a monophyletic lineage that separated anciently into Tonatia and Lophostoma. Within the Tonatia lineage, T. bidens and T. saurophila are sister taxa but are divergent for both nuclear and mitochondrial sequences. Nuclear data suggest that L. silvicolum may be paraphyletic, as currently recognized, because L. evotis appears within this clade.

Previous understanding of the relationships among the species of bats in the genus Eumops has been primarily based on phenetic and cladistic analyses of morphological genetic similarity data. The objective of this study was to construct a phylogeny using DNA sequence data from 2 mitochondrial loci (cytochrome-b [Cytb] and nicotinamide adenine dinucleotide dehydrogenase subunit 1 [ND1]) and 1 nuclear locus (b-fibrinogen intron 7 [bFib]) for members of Eumops and outgroups from the family Molossidae. Data for each locus were analyzed separately using maximum-likelihood and Bayesian methods and combined for complete data analyses using Bayesian inference and Bayesian concordance analysis on a total of 2,715 base pairs. The monophyly of Eumops was significantly supported in all analyses and molecular dating estimated a most recent common ancestor of the genus at approximately 15.7 million years ago. Placement of E. hansae was problematic, with ND1 analyses supporting a sister relationship with E. patagonicus and E. nanus, whereas Cytb and bFib analyses placed this species as a basal lineage in the genus. Analysis of all genes recovered E. hansae as a poorly supported basal lineage with E. patagonicus and E. nanus as sister to the remaining species. These 3 major lineages of Eumops diverged during the mid-Miocene.

Old World fruit bats (Chiroptera: Yinpterochiroptera: Pteropodidae) are a diverse radiation endemic to the tropics of Africa, Asia, Australia, and nearby island archipelagos. Recent molecular analyses have provided considerable resolution of phylogenetic relationships within this group, but many points of uncertainty have remained including the position of several enigmatic taxa (e.g., Notopteris, Eidolon), relationships among species in more diverse subfamilies and genera (e.g., Pteropodinae, Pteropus, Epomophorus), and topology of the backbone of the tree. Here we provide a new, synthetic analysis including representatives of all 45 currently recognized genera and enhanced sampling in several speciose genera. Our matrix included four nuclear genes regions (vWF, RAG1, RAG2, and BRCA1) and four mitochondrial gene loci (Cytb, tRNA valine, 12S rRNA, and 16S rRNA) for a total of >8000 bp including new sequence data for 13 species. Maximum likelihood and Bayesian analyses resulted in trees supporting recognition of six main suprageneric clades similar in content to those identified in our previous studies. We did not recover strong support for relationships among the main clades along
