“…Following the phylogenetic hypothesis of Teeling et al (2005) and Miller-Butterworth et al (2007), Myzopoda originated from a Neotropical noctilionid ancestor that dispersed to Madagascar from South America during the early Eocene. This scenario is in stark contrast to recent phylogeographic studies on Malagasy bats which demonstrate colonization from Africa across the Mozambique Channel (Russell et al 2008;Ratrimomanarivo et al 2007Ratrimomanarivo et al , 2008 or from Asia O'Brien et al 2009). …”

Cross-species chromosome painting in bats from Madagascar: the contribution of Myzopodidae to revealing ancestral syntenies in Chiroptera

The chiropteran fauna of Madagascar comprises eight of the 19 recognized families of bats, including the endemic Myzopodidae. While recent systematic studies of Malagasy bats have contributed to our understanding of the morphological and genetic diversity of the island's fauna, little is known about their cytosystematics. Here we investigate karyotypic relationships among four species, representing four families of Chiroptera endemic to the Malagasy region using cross-species chromosome painting with painting probes of Myotis myotis: Myzopodidae (Myzopoda aurita, 2n = 26), Molossidae (Mormopterus jugularis, 2n = 48), Miniopteridae (Miniopterus griveaudi, 2n = 46), and Vespertilionidae (Myotis goudoti, 2n = 44). This study represents the first time a member of the family Myzopodidae has been investigated using chromosome painting. Painting probes of M. myotis were used to delimit 29, 24, 23, and 22 homologous chromosomal segments in the genomes of M. aurita, M. jugularis, M. griveaudi, and M. goudoti, respectively. Comparison of GTG-banded homologous chromosomes/chromosomal segments among the four species revealed the genome of M. aurita has been structured through 14 fusions of chromosomes and chromosomal segments of M. myotis chromosomes leading to a karyotype consisting solely of bi-armed chromosomes. In addition, chromosome painting revealed a novel X-autosome translocation in M. aurita. Comparison of our results with published chromosome maps provided further evidence for karyotypic conservatism within the genera Mormopterus, Miniopterus, and Myotis. Mapping of chromosomal rearrangements onto a molecular consensus phylogeny revealed ancestral syntenies shared between Myzopoda and other bat species of the infraorders Pteropodiformes and Vespertilioniformes. Our study provides further evidence for the involvement of Robertsonian (Rb) translocations and fusions/fissions in chromosomal evolution within Chiroptera.

“…To account for statistical nonindependence of data resulting from the shared phylogenetic history of the six species (Felsenstein, 1985), we repeated that analysis accounting for phylogeny using a generalized least squares (GLS) model. We used a consensus tree of several recent pteropodid phylogenies (Giannini and Simmons, 2005;Jones et al, 2002;O'Brien et al, 2009), with branch lengths scaled using the method of Pagel (Pagel, 1992). GLM analyses with phylogeny were carried out using REGRESSIONv2 (Lavin et al, 2008) in Matlab.…”

modes of bats vary widely among families, so we focused on a single family, the Pteropodidae. This family consists of ca. 186 species distributed throughout the paleotropics (Wilson and Reeder, 2005) and is characterized by fruit and nectar-feeding, non-echolocating Accepted 26 None of the bats in our study flew at constant speed, so we used multiple regression to isolate the changes in wing kinematics that correlated with changes in flight speed, horizontal acceleration and vertical acceleration. We uncovered several significant trends that were consistent among species. Our results demonstrate that for medium-to large-sized bats, the ways that bats modulate their wing kinematics to produce thrust and lift over the course of a wingbeat cycle are independent of body size.

“…Simmons (2005) recognized 65 species of Pteropus, with most identifications largely following the taxonomy proposed by Anderson (1912) based on morphological characters and geography. Previous phylogenetic studies indicate a need for further investigation to resolve Pteropus phylogeny (O'Brien et al 2009;Giannini et al 2008) because their findings suggest that the genus may not be monophyletic. Furthermore, species endemic to isolated islands are underrepresented in these studies.…”

The Mariana flying fox (Pteropus mariannus) has suffered substantial decline in recent years. Taxonomic classification of P. mariannus has been inconsistent, with subspecies designations based mainly on geography and morphological variation within small sample sizes. In this study, we examine relationships of P. mariannus across two island groups in the western Pacific Ocean. Microsatellite data and mitochondrial sequences, from D-loop, cytochrome oxidase I, and cytochrome b, suggest that the population on the islands of Palau is genetically isolated from the populations in the Mariana Islands. Our data confirm that the bats of Palau should be considered a separate conservation unit from the bats of the Mariana Islands, supporting the current subspecies separation of these two populations. Our results also suggest that there is gene flow among islands within the Mariana archipelago and that the bats on these islands, currently classified as two subspecies, should be managed as a single conservation unit, although we refrain from suggesting taxonomic revisions until genetic and morphological data become available from geographically intermediate populations.
