“…5, Table 3). The MRP supertree concurs with the majority of the source trees dividing the family into two groups, the subfamilies Taphozoinae (Taphozous and Saccolaimus) and Emballonurinae (other emballonurid genera) (Barghoorn, 1977 ;Griffiths & Smith, 1991 ;Robbins & Sarich, 1988 ;Kirsch et al, 1998 ;Dunlop, 1998). Within Emballo-nurinae, the supertree supports the monophyly of the tribes Emballonurini (Emballonura, Mosia and Coleura) and the New World tribe Diclidurini (Cyttarops, Diclidurus, Rhynchonycteris, Cormura, Saccopteryx, Balantiopteryx, Pteropteryx and Centronycteris).…”

“…For example, Noctilionoidea (Phyllostomidae, Mormoopidae, Noctilionidae) is monophyletic in the supertree due to being supported in the majority of the source topologies. The addition of Mystacinidae to this clade in the supertree receives support from recent molecular Kirsch et al, 1998 ;Van Den Bussche & Hoofer, 2001) and other morphological studies (Novacek, 1980 ;Simmons & Conway, 2001). Monophyly of the superfamily Vespertilionoidea is not supported in the supertree.…”

“…There is strong support for this relationship (Appendix 2). The supertree does not support the diphyly of Microchiroptera as suggested by the molecular studies of Teeling et al (2000) and Kirsch and colleagues (Hutcheon et al, 1998 ;Kirsch et al, 1998 ;Kirsch & Pettigrew, 1998 ;Pettigrew & Kirsch, 1998). Microchiropteran monophyly is supported by the majority of the morphological studies to date and some molecular studies (e.g.…”

Most controversial is the suggestion that the microbat superfamily Rhinolophoidea is more closely associated to Pteropodidae (Megachiroptera) than to any other microchiropteran clades, thereby rendering the Microchiroptera polyphyletic (Pettigrew and Kirsch and Pettigrew, 1998 ;Hutcheon et al, 1998 ;Kirsch et al, 1998 ;Teeling et al, 2000 ;Madsen et al, 2001 ;Springer et al, 2001).

“…More recently, there has been a substantial improvement in our understanding of bat phylogeny at both the higher and lower taxonomic levels (e.g. Bogdanowicz & Owen, 1998 ;Kirsch et al, 1998 ;Simmons & Geisler, 1998 ;Teeling et al, 2000 ;Van Den Bussche & Hoofer, 2001). However, as yet there is no single bat phylogeny that covers all extant species and was derived using a robust methodology.…”

A phylogenetic supertree of the bats (Mammalia: Chiroptera)

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 locused 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.

Recently Reig & Roche (1999) have suggested a third sub-group of systems; the X Per like systems. Their main characteristics are: long pulse periods (typically 1000s), persistent low L x (∼ 10 34 erg/s) and low variability, and rare uncorrelated weak Xray outbursts. The properties of all three groups are summarised in Table 5.1.Currently (August 2003) there are about 100 known or suspected HMXBs (see Figure 5.1). Surprisingly, nearly one third of these lie in the Magellanic Clouds. This very large fraction, particularily noticeable in the SMC, will be discussed later. About one third of all the HMXBs have no known optical counterpart, simply due to the historical inaccuracy of the X-ray location. Current facilities such as the Chandra X-ray Observatory are very effective tools to rectify this situation.Progress towards a better understanding of the physics of these systems depends on multi-wavelength studies. From observations of the Be star in the optical, UV and IR, the physical conditions under which the neutron star is accreting can be determined. In combination with hard X-ray timing observations, this yields a near complete picture of the accretion process. It is thus vital to identify the optical counterparts and obtain UV to IR measurements for these X-ray systems in order to further our understanding. * N.B. the Paczynski relation is only valid for q > 1, and there is a more accurate algorithm (Eggleton 1983) which is valid for all q.

We report on the results obtained for the millisecond transient X-ray pulsar XTE J1807-294 in a 40 min orbital period system, based on an XMM-Newton ToO observation carried out during March 2003. The source was found at a luminosity level of about 2 × 10 36 erg s −1 in the 0.5-10 keV range (assuming a distance of 8 kpc). We confirm the presence of the 5.25 ms pulsations (after accounting for the orbital modulation) and find a pulsed fraction of 5.8% in the 0.3-10 keV band. The pulse shape in nearly sinusoidal. The spectral continuum of the source is well fitted by an absorbed Comptonization model plus a soft component. No emission or absorption lines have been detected in the 0.5-10 keV range with upper limits of 10-40 eV. The reported analysis represent the first detailed study of this source, the fourth belonging to the ultra-compact binary system class hosting an accreting neutron star.
