Phylogeography of the greater horseshoe bat, Rhinolophus ferrumequinum: contrasting results from mitochondrial and microsatellite data

MOLECULAR ECOLOGY, Issue 2 2009
JON FLANDERS
Abstract Phylogeographical studies are typically based on haplotype data, occasionally on nuclear markers such as microsatellites, but rarely combine both. This is unfortunate because the use of markers with contrasting modes of inheritance and rates of evolution might provide a more accurate and comprehensive understanding of a species' history. Here we present a detailed study of the phylogeography of the greater horseshoe bat, Rhinolophus ferrumequinum, using 1098 bp of the mitochondrial ND2 gene from 45 localities from across its Palaearctic range to infer population history. In addition, we re-analysed a large microsatellite data set available for this species and compared the results of both markers to infer population relationships and the historical processes influencing them. We show that mtDNA, the most popular marker in phylogeography studies, yielded a misleading result, and would have led us to conclude erroneously that a single expansion had taken place in Europe. Only by combining the mitochondrial and microsatellite data sets are we able to reconstruct the species' history and show two colonization events in Europe, one before the Last Glacial Maximum (LGM) and one after it. Combining markers also revealed the importance of Asia Minor as an ancient refugium for this species and a source population for the expansion of the greater horseshoe bat into Europe before the LGM.

Phylogeography and postglacial expansion of Mus musculus domesticus inferred from mitochondrial DNA coalescent, from Iran to Europe

MOLECULAR ECOLOGY, Issue 2 2008
HASSAN RAJABI-MAHAM
Abstract Few genetic data document the postglacial history of the western house mouse, Mus musculus domesticus. We address this by studying a sample from the southeastern tip of the Fertile Crescent in the Iranian province of Ahvaz. Including other published and unpublished data from France, Germany, Italy, Bulgaria, Turkey and other places in Iran, altogether 321 mitochondrial D-loop sequences are simultaneously analysed. The patterns of coalescence obtained corroborate the classical proposal according to which the Fertile Crescent is where commensalism with humans has started in the Western Hemisphere, and from where the subspecies has expanded further west. Our data also clearly show that despite multiple colonisations and long-range transportation, there is still a rather high ,ST of 0.39. The original expansion signal is still recognisable, with two well-separated derived clades, allowing us to propose a hypothetical scenario in which expansion toward Europe and Asia Minor took at least two routes, tentatively termed the Mediterranean and the Bosphorus/Black Sea routes. This scenario resembles that of another domesticated species, the goat, and fits with the known progression of Neolithic culture. Given the concomitance of both phenomena around 12 000 years ago, we propose a recalibration of the D-loop mutation rate to a much faster tick of ~40% per site per million years (Myr). This value should be used for intrasubspecific polymorphism, while the interspecific rate in Mus is presently estimated at 6,10%/site/Myr. This is in keeping with the now well recognised fact that only a subfraction of segregating mutations go to fixation. [source]


Plastid DNA variation in the Dactylorhiza incarnata/maculata polyploid complex and the origin of allotetraploid D. sphagnicola (Orchidaceae)

MOLECULAR ECOLOGY, Issue 10 2003
M. Hedrén
Abstract To obtain further information on the polyploid dynamics of the the Dactylorhiza incarnata/maculata polyploid complex and the origin of the allotetraploid D. sphagnicola (Orchidaceae), plastid DNA variation was studied in 400 plants from from Sweden and elsewhere in Europe and Asia Minor by means of polymerase chain reaction,restriction fragment length polymorphisms (PCR-RFLPs) and sequencing. Allotetraploid taxa in Europe are known have evolved by multiple independent polyploidization events following hybridization between the same set of two distinct ancestral lineages. Most allotetraploids have inherited the plastid genome from parents similar to D. maculata sensu lato, which includes, e.g. the diploid D. fuchsii and the autotetraploid D. maculata sensu stricto. D. sphagnicola carries a separate plastid haplotype different from the one found in other allotetraploid taxa, which is in agreement with an independent origin from the parental lineages. Some of the remaining allotetraploids have local distributions and appear to be of postglacial origin, whereas still other allotetraploids may be of higher age, carrying plastid haplotypes that have not been encountered in present day representatives of the parental lineages. Introgression and hybridization between diploids and allotetraploids, and between different independently derived allotetraploids may further have contributed to genetic diversity at the tetraploid level. Overall, the Dactylorhiza polyploid complex illustrates how taxon diversity and genetic diversity may be replenished rapidly in a recently glaciated area. [source]


ANATOLIA AND THE BALKANS, ONCE AGAIN , RING-SHAPED IDOLS FROM WESTERN ASIA AND A CRITICAL REASSESSMENT OF SOME ,EARLY BRONZE AGE' ITEMS FROM ,K,ZTEPE, TURKEY

OXFORD JOURNAL OF ARCHAEOLOGY, Issue 1 2007
THOMAS ZIMMERMANN
Summary. The ring-shaped idol pendant, a distinctive type of Chalcolithic ritual (?) jewellery, is discussed with regard to its chronology in the Balkans in light of its occasional appearance in Asia Minor. Known from domestic contexts, funerals and hoards (?), none of the so far documented Anatolian pendants (clearly another aspect testifying to the well-known Anatolian,Balkan connections in the fourth millennium BC) can be dated later than the Late Chalcolithic/Early Bronze Age I. This fact provides further evidence for the developing hypothesis that certain inventories from ,kiztepe, the only prehistoric reference site on the Turkish Black Sea coast excavated on a large scale, need some profound chronological redating. Selected features and levels dated to ,Early Bronze Age II,III' at ,kiztepe seem to be several centuries older than currently believed, which has implications for the overall chronological range of these pendants.

Mountain torques and synoptic systems in the Mediterranean

THE QUARTERLY JOURNAL OF THE ROYAL METEOROLOGICAL SOCIETY, Issue 634 2008
Joseph Egger
Abstract The mountains surrounding the Mediterranean exert torques T during the passage of North Atlantic systems which affect the angular momentum of the airflow passing over and around the massifs. The Alps, the Atlas range and the orographic block of Asia Minor are selected to investigate the typical flow conditions during torque events. These mountain ranges are small enough to justify a local angular momentum analysis. Both the zonal and the meridional components of a mountain's torque (T, and T,) are used as stratification parameters in a statistical investigation of the interaction of large-scale perturbations with this mountain. How are these flows affected by the obstacle? A simple scheme is tested which attempts to interpret results. The torque analysis singles out eastward-moving large-scale systems. Their isobars are oriented from southwest (northwest) to northeast (southeast) near the mountain in zonal torque T, (T,) cases. The massifs tend to generate a low-level distortion of the pressure field such that the angular momentum of the flow over the mountain is reduced. These results can be explained within the framework of the scheme. The influence of the mountains on the pressure field is seen only at heights ,4000 m. The low-level distortions of the pressure field contribute positively to the total torque for lags ,,0 in the Alps and for all lags , 2,,,2 days in Asia Minor, where only T, is evaluated. The impact of the Atlas mountains is seen only at , = 0. Copyright © 2008 Royal Meteorological Society [source]


GPR, ERT and magnetic investigations inside the Martyrium of St Philip, Hierapolis, Turkey

ARCHAEOLOGICAL PROSPECTION, Issue 3 2009
Luigia Nuzzo
Abstract Hierapolis, Denizli, Turkey, was one of the most important Hellenistic-Roman cities in Asia Minor. Located about 250,km east of Izmir, the area is a UNESCO World Heritage Site because of its magnificent archaeological remains and the white travertine pool formations created by its peculiar geothermal setting. The Italian Archaeological Mission in more than 50 years of activity in Hierapolis has brought to light and restored important vestiges of the ancient city, helping to understand the urban layout in the various epochs of its development. In 2001,2003 geophysical surveys were performed by the University of Lecce in several areas inside the archaeological site of Hierapolis to support the archaeological excavations. This paper reports the results of the integrated geophysical surveys performed in 2003 inside the Martyrium of Saint Philip, a mausoleum built on the place where it is believed that the Apostle was martyred. Ground-penetrating radar (GPR), electrical resistivity tomography (ERT) and magnetic gradient investigations were carried out in the central octagonal room, whereas the accessible lateral rooms were surveyed with GPR and occasionally ERT. The acquisition was performed along a series of closely spaced lines and the processed data were visualized as two-dimensional vertical sections (GPR), map view (magnetic gradiometry), depth slices or three-dimensional volumes (GPR and ERT) to allow an integrated interpretation of the geophysical results. The analysis of the geophysical datasets revealed a series of anomalies in both the central and lateral rooms that could be ascribed to the building foundations and to other possible archaeological structures, probably related to earlier stages of the sacred building and to tombs, as well as other anomalies (voids, fractures) of presumable natural origin.

ON THE WHITE AND COLOURED MARBLES OF THE ROMAN TOWN OF CUICUL (DJEMILA, ALGERIA)

ARCHAEOMETRY, Issue 4 2010
F. ANTONELLI
This paper reports the results of an archaeometric study of the local and imported marbles found in the Roman town of Cuicul (now Djemila, Algeria), a research project funded by the Sixth Framework Programme of the European Union. Of the few imported coloured lithotypes that have been found, four are of Greek origin and one was imported from Asia Minor. In addition, two other classical Roman coloured stones found on the site are probably of local North African origin (most likely one from Numidia and one from Algeria). With regard to the grey and white marbles employed in the statuary and architecture, petrographic study in thin section and the ,13C and ,18O isotopic data emphasize the frequent use of the local fine-grained lithotype from Filfila (Skikda) together with imported Greek lithotypes (i.e., Pentelic marble, the dolomitic variety of Thasian marble, and Parian marble from Lakkoi) as well as different varieties of the so-called ,greco scritto', whose provenance in some cases still remains uncertain. In fact, the petrographic and geochemical features of the marbles do not always match those known for the classical ,greco scritto' from the quarry of Cap de Garde, near Annaba (Algeria). [source]


THE ,FRYING PANS' OF THE EARLY BRONZE AGE AEGEAN: AN EXPERIMENTAL APPROACH TO THEIR POSSIBLE USE AS LIQUID MIRRORS,

ARCHAEOMETRY, Issue 4 2009
D. A. PAPATHANASSOGLOU
The so-called ,frying pans' are peculiar vessels, most of them made of terracotta, flat and shallow, usually decorated on the outside part and dated to the Early Bronze Age. They were unearthed mostly in the Cyclades, in Crete and on the Helladic mainland. There are also a few artefacts made of stone and of bronze, from the Cyclades and Asia Minor, respectively. The intended purpose of these objects is disputed. Several interpretations exist for their function, the earliest one being that of liquid mirror vessels. We investigated the mirror hypothesis experimentally, by testing trays with attributes similar to those of the original ,frying pans', filled with a series of liquids familiar to the people of the time and the place where those vessels were made. The criterion employed was the contrast of mirror images. We conclude that, provided that some minimal prerequisites are met, the ,frying pans' are quite appropriate as liquid mirror vessels. [source]
