characterization of dinucleotide microsatellite loci in big brown bats eptesicus fuscus and their use in other north american vespertilionid bats
Molecular Ecology Notes, 2002Co-Authors: Maarten J Vonhof, M B Fenton, Corey S. Davis, Curtis StrobeckAbstract:We describe the development of six microsatellite loci for big brown bats, Eptesicus fuscus. Microsatellite markers were isolated from a small insert genomic library, and tested on a population of 44 animals from the Pend d’Oreille Valley, in southeastern British Columbia, Canada. These six loci were highly variable, with 12–23 alleles per locus, and observed and expected heterozygosities of greater than 79.5%. The six primer sets, and three others that were not variable in E. fuscus, were tested on 11 other species in the families Vespertilionidae and Antrozoidae. All the tested loci amplified highly variable products in at least several other species.

Hidden diversity of Nycteribiidae (Diptera) bat flies from the Malagasy region and insights on host-parasite interactions.
Parasites & vectors, 2017Co-Authors: Beza Ramasindrazana, Steven M. Goodman, Yann Gomard, Carl W. Dick, Pablo TortosaAbstract:We present information on Nycteribiidae flies parasitizing the bat families Pteropodidae, Miniopteridae and Vespertilionidae from the Malagasy Region, contributing insight into their diversity and host preference. Our phylogenetic analysis identified nine clusters of nycteribiid bat flies on Madagascar and the neighbouring Comoros Archipelago. Bat flies sampled from frugivorous bats of the family Pteropodidae are monoxenous: Eucampsipoda madagascariensis, E. theodori and Cyclopodia dubia appear wholly restricted to Rousettus madagascariensis, R. obliviosus and Eidolon dupreanum, respectively. Two different host preference patterns occurred in nycteribiids infecting insectivorous bats. Flies parasitizing bats of the genera Miniopterus (Miniopteridae) and Myotis (Vespertilionidae), namely Penicillidia leptothrinax, Penicillidia sp. and Nycteribia stylidiopsis, are polyxenous and showed little host preference, while those parasitizing the genera Pipistrellus and Scotophilus (both Vespertilionidae) and referable to Basilia spp., are monoxenous. Lastly, the inferred Bayesian phylogeny revealed that the genus Basilia, as currently configured, is paraphyletic. This study provides new information on the differentiation of nycteribiid taxa, including undescribed species. Host preference is either strict as exemplified by flies parasitizing fruit bats, or more relaxed as found on some insectivorous bat species, possibly because of roost site sharing. Detailed taxonomic work is needed to address three undescribed nycteribiid taxa found on Pipistrellus and Scotophilus, tentatively allocated to the genus Basilia, but possibly warranting different generic allocation.

RESEARCH ARTICLE Diversity, Host Specialization, and Geographic Structure of Filarial Nematodes Infecting Malagasy Bats
2016Co-Authors: Beza Ramasindrazana, Steven M. Goodman, Koussay Dellagi, Erwan Lagadec, Milijaona R, Pablo TortosaAbstract:We investigated filarial infection in Malagasy bats to gain insights into the diversity of these parasites and explore the factors shaping their distribution. Samples were obtained from 947 individual bats collected from 52 sites on Madagascar and representing 31 of the 44 species currently recognized on the island. Samples were screened for the presence of micro- and macro-parasites through both molecular and morphological approaches. Phylo-genetic analyses showed that filarial diversity in Malagasy bats formed three main groups, the most common represented by Litomosa spp. infectingMiniopterus spp. (Miniopteridae); a second group infecting Pipistrellus cf. hesperidus (Vespertilionidae) embedded within the Litomosoides cluster, which is recognized herein for the first time from Madagascar; and a third group composed of lineages with no clear genetic relationship to both previously described filarial nematodes and found inM. griveaudi,Myotis goudoti, Neoromicia matroka (Vespertilionidae),Otomops madagascariensis (Molossidae), and Paratriaenops furculus (Hipposideridae). We further analyzed the infection rates and distribution pattern of Litomosa spp., which was the most diverse and prevalent filarial taxon in our sample. Filaria

Diversity, Host Specialization, and Geographic Structure of Filarial Nematodes Infecting Malagasy Bats
PLoS ONE, 2016Co-Authors: Beza Ramasindrazana, Steven Goodman, Koussay Dellagi, Erwan Lagadec, Milijaona Randrianarivelojosia, Pablo TortosaAbstract:We investigated filarial infection in Malagasy bats to gain insights into the diversity of these parasites and explore the factors shaping their distribution.

We further analyzed the infection rates and distribution pattern of Litomosa spp., which was the most diverse and prevalent filarial taxon in our sample. Filarial infection was disproportionally more common in males than females in Miniopterus spp., which might be explained by some aspect of roosting behavior of these cave-dwelling bats. We also found marked geographic structure in the three Litomosa clades, mainly linked to bioclimatic conditions rather than host-parasite associations. While this study demonstrates distinct patterns of filarial nematode infection in Malagasy bats and highlights potential drivers of associated geographic distributions, future work should focus on their alpha taxon-omy and characterize arthropod vectors.

karyotype relationships of six bat species chiroptera Vespertilionidae from china revealed by chromosome painting and g banding comparison
Cytogenetic and Genome Research, 2006Co-Authors: Q Feng, Marianne Volleth, J Wang, P C M Obrien, Xiuguang Mao, Y Wang, Fengtang Yang, Wenhui NieAbstract:The Vespertilionidae is the largest family in the order Chiroptera and has a worldwide distribution in the temperate and tropical regions. In order to further clarify the karyotype relationships at the lower taxonomic level in Vespertilionidae, genome-wide comparative maps have been constructed between Myotis myotis (MMY, 2n = 44) and six vesper bats from China: Myotis altarium (MAL, 2n = 44), Hypsugo pulveratus (HPU, 2n = 44), Nyctalus velutinus (NVE, 2n = 36), Tylonycteris robustula (TRO, 2n = 32), Tylonycteris sp. (TSP, 2n = 30)and Miniopterus fuliginosus (MFU, 2n = 46) by cross-species chromosome painting with a set of painting probes derived from flow-sorted chromosomes of Myotis myotis. Each Myotis myotis autosomal probe detected a single homologous chromosomal segment in the genomes of these six vesper bats except for MMY chromosome 3/4 paint which hybridized onto two chromosomes in the genome of M. fuliginosus. Our results show that Robertsonian translocation is the main mode of karyotype evolution in Vespertilionidae and that the addition of heterochromatic material also plays an important role in the karyotypic evolution of the genera Tylonycteris and Nyctalus. Two conserved syntenic associations (MMY9 + 23 and 18 + 19) could be the synapomorphic features for the genus Tylonycteris. The integration of our maps with the published maps has enabled us to deduce chromosomal homologies between human and these six vesper bats and provided new insight into the karyotype evolution of the family Vespertilionidae.

description of a cryptic species spinturnix bechsteini n sp acari mesostigmata spinturnicidae parasite of myotis bechsteinii kuhl 1817 chiroptera Vespertilionidae by using ecoethology of host bats and statistical methods
Journal of Medical Entomology, 2004Co-Authors: Jean Deunff, Gottfried Walter, Alain Bellido, Marianne VollethAbstract:Using ecoethology of bats and statistical methods, we anticipate the evidence of specific species of spinturnicids associated with Myotis myotis and Myotis bechsteinii (Chiroptera, Vespertilionidae) mixed colonies are unknown. Traditional description of this new crpytic species Spinturnix bechsteini, parasite of M. bechsteinii, is done. Statistical approach is based on analysis of variance and principal component analysis. The current knowledge on parasites of the genus Myotis in the West Palearctic subregion is presented.

systematic implications of chromosome gtg band and bacula morphology for southern african eptesicus and pipistrellus and several other species of vespertilioninae chiroptera Vespertilionidae
Acta Chiropterologica, 2002Co-Authors: Teresa Kearney, Marianne Volleth, G Contrafatto, Peter J TaylorAbstract:Phylogenetic analyses of bacular and chromosomal GTG-band characters verify the suggestion that Eptesicus hottentotus (A. Smith, 1833) is the only true Eptesicus Rafinesque, 1820 of the six southern African species (capensis, cf. melckorum, rendalli, somalicus and zuluensis) formerly classified as Eptesicus. GTG-banded chromosomes studied in rendalli, zuluensis and capensis confirm the affiliation of all of them to the genus Neoromicia; these species were previously placed in the Pipistrellus Kaup, 1829, subgenus Neoromicia based on bacular morphology. For karyological reasons, the elevation of the subgenus Neoromicia to generic rank is established by the presence of three Robertsonian fusion chromosomes (7/11, 8/9, 10/12) as distinguishing characters. The move of Hypsugo nanus and cf. melckorum to the genus Neoromicia is indicated by chromosomal analysis and bacular morphology, respectively. The close phylogenetic relationship between Pipistrellus cf. kuhlii and P. rusticus is shown by a shared Robertson...

cryptic mammalian species a new species of whiskered bat myotis alcathoe n sp in europe
Naturwissenschaften, 2001Co-Authors: O. Von Helversen, Klaus-gerhard Heller, Marianne Volleth, Frieder Mayer, A Nemeth, P GombkotoAbstract:The analysis of morphological, behavioural and genetic characters of whiskered bats revealed a new European bat species within the family Vespertilionidae. We describe the morphology, karyology, genetic similarity, ecology and distribution of Myotis alcathoe n. sp. It closely resembles Myotis mystacinus, Myotis brandtii and Myotis ikonnikovi in morphology, but all four species show clear genetic differences in two mitochondrial genes (ND1 and 12S rRNA). Myotis alcathoe n. sp. is the smallest species among the European whiskered bats and uses the highest-frequency echolocation calls of all the European Myotis species. It prefers to hunt in small valleys with deciduous trees and flowing water, which is an endangered habitat. Records from Greece and Hungary indicate a distribution range in south-eastern Europe.

Karyotype comparison and phylogenetic relationships of Pipistrellus-like bats (Vespertilionidae; Chiroptera; Mammalia)
Chromosome research : an international journal on the molecular supramolecular and evolutionary aspects of chromosome biology, 2001Co-Authors: Marianne Volleth, Klaus-gerhard Heller, Gary N. Bronner, Martin C. Göpfert, O. Von Helversen, Hoi-sen YongAbstract:Detailed karyotype descriptions of 20 Pipistrellus-like bat species belonging to the family Vespertilionidae are presented. For the first time, chromosomal complements of four species, i.e. Pipistrellus stenopterus (2n = 32), P. javanicus (2n = 34), Hypsugo eisentrauti (2n = 42) and H. crassulus (2n = 30) are reported. A Pipistrellus kuhlii-like species from Madagascar represents a separate species distinguished from the European Pipistrellus kuhlii (2n = 44) by a diploid chromosome number of 42. Banded karyotypes are presented for the first time for Scotozous dormeri, Hypsugo capensis, Hesperoptenus blanfordi, Tylonycteris pachypus and robustula. Chromosomal evolution in the family Vespertilionidae is characterized by the conservation of entire chromosomal arms and reductions in diploid chromosome number via Robertsonian fusions. Less frequently, centric fissions, para- and pericentric inversions and centromere shifts were found to have occurred. In several cases a certain type of chromosomal change predominates in a karyotype. Examples of this are the acquisition of interstitial heterochromatic bands in Tylonycteris robustula, and centric shifts in P. javanicus, H. eisentrauti and Hesp. blanfordi. The species examined here belong to three tribes, i.e. Pipistrellini, Vespertilionini and Eptesicini, which are distinguished by chromosomal characteristics. According to our results, the species Pipistrellus (Neoromicia) capensis belongs to the Vespertilionini and not to the Pipistrellini. We therefore propose to elevate the subgenus Neoromicia to generic rank.
