“…On the contrary, at least for diving beetles the Pyrenees and the Ebro valley seem to have been almost insurmountable geographical barriers during most of the Pleistocene, isolating Iberian populations from those in the rest of Europe long enough for them to speciate in allopatry. This will be in agreement with recent work on other taxa, for which during the Pleistocene glaciations Iberia (and other peninsulas in southern Europe) could have remained isolated rather than being a refuge from where to re-colonise northern areas during the interglacials (Bilton et al, 1998;Kropf et al, 2002;Michaux et al, 2003). For these taxa, northern refuges could be the source of most present-day central and north European populations (e.g.…”

The phylogenetic relationships and the geographical origin of 27 of the 34 species and of 3 of the 9 subspecies of Iberian endemic Dytiscidae are studied, based on species level phylogenies constructed with two mitochondrial gene fragments (16S rRNA and Cytochrome Oxidase I). All Iberian endemic species for which more than one specimen was included were monophyletic with the exception of the complex Deronectes aubei sanfilippoi Fery & Brancucci, 1997-D. delarouzei (Jac. Du Val, 1857 (Sharp, 1872) and Hydroporus normandi normandi Régimbart, 1903 do not form well characterised lineages, as measured with the mitochondrial markers used in this study.The Iberian endemic species of Dytiscidae are divided in three groups according to the type of vicariant origin: 1) within-Iberian species, when the sister species (or clade) of the Iberian endemic is also and Iberian endemic; 2) Iberian/European, when the sister occurs in Europe north of the Pyrenees; and 3) Iberian/North African, when the sister occurs in North Africa. Within-Iberian endemics are found to be on average older than Iberian/European and Iberian/North African species, they have more restricted distributions within the Iberian peninsula (they occur typically in only one of the main biogeographical regions), and tend to occur exclusively in running waters. The withinIberian species are best represented by the "Iberian" clade of the genus Deronectes, formed by six endemic species plus two species with wider distributions. Most species in this group originated in rapid succession in the Late Miocene-Early Pliocene boundary by repeated vicariant events in the three main mountain massifs in the Iberian peninsula: the Pyrenees, the Baetic ranges, and the Sistema Central plus mountain massifs of the NW. On the contrary, most of the Iberian/European species seem to be the recent (Pleistocene) vicariants of a species with a widespread distribution encompassing the Iberian peninsula, at present restricted to south and west of the Ebro valley. The results of these analyses suggest that the Iberian peninsula was an isolated refuge during the Quaternary glaciations, in where allopatric speciation was frequent among some lineages of Dytiscidae diving beetles.

“…This event is situated in the Lower Pleistocene, 1.1 Myr BP. A refugium northwest of the Caucasus was suggested by Hewitt (1999) for the European oak (Quercus robur-petraea complex) and by Jaarola and Searle (2002) for the Weld vole (Microtus agrestis), or north of the Caspian Sea, as well as Crimea, as hypothesised by Bilton et al (1998) for small European mammals showing a recent northern distribution. Clade II is the only one showing evidence of population expansion after a bottleneck, which is supported by a low nucleotide diversity (0.007), despite the large sample size (n D 33) and more than 4500 km separating the more distant samples.…”

“…Temperate species, which presently occupy central and northern Europe, mainly derive from Mediterranean refugium populations that underwent range expansion in the late glacial and early post-glacial periods (Hewitt, 1996), with a western form deriving from an Iberian refugium and an eastern form from the Italo-Balkanic refugium (Dumolin-Lapegue et al, 1997;Ferris et al, 1993Ferris et al, , 1998Santucci et al, 1998;Thorpe, 1984). Several authors, however, suggest an additional mode of colonisation of central and northern Europe by non-Mediterranean populations, coming from one or more eastern refugia: Caucasus, southern Ural, central Europe, and western Asia (Bilton et al, 1998;Cooper et al, 1995;Michaux et al, 2004;Nesbo et al, 1999;Palme and Vendramin, 2002;Seddon et al, 2002). A few other species (BrunhoV et al, 2003;Taberlet et al, 1998) …”

We sequenced 998 base pairs (bp) of mitochondrial DNA cytochrome b and 799 bp of nuclear gene BRCA1 in the Lesser white-toothed shrew (Crocidura suaveolens group) over its geographic range from Portugal to Japan. The aims of the study were to identify the main clades within the group and respective refugia resulting from Pleistocene glaciations. Analyses revealed the Asian lesser white-toothed shrew (C. shantungensis) as the basal clade, followed by a major branch of C. suaveolens, subdivided sensu stricto into six clades, which split-up in the Upper Pliocene and Lower Pleistocene (1.9-0.9 Myr). The largest clade, occurring over a huge range from east Europe to Mongolia, shows evidence of population expansion after a bottleneck. West European clades originated from Iberian and Italo-Balkanic refugia. In the Near East, three clades evolved in an apparent hotspot of refugia (west Turkey, south-west and south-east of the Caucasus). Most clades include specimens of diVerent morphotypes and the validity of many taxa in the C. suaveolens group has to be re-evaluated. 

“…1). Similarly, some species such as the brown bear (Ursus arctos) (Taberlet et al, 1998) or different small mammal species [Clethrionomys glareolus (Deffontaine et al, 2005); Sorex minutus and S. araneus (Bilton et al, 1998) and M. arvalis (Jaarola and Searle, 2004) and M. oeconomus (Brunhoff et al, 2003)] display genetic lineages suggesting that these species also survived in more easterly refuges (the Caucasus or the southern Urals) and in Central Europe (Kotlı´k et al, 2006). Moreover, the examination of the fossil record of European temperate species during the last ice age (26000-13000 years ago) reveals that environmental conditions were not severe enough in these regions to prevent the survival of forest-dependent species, notably in Poland (Sommer and Nadachowski, 2006).…”

Geography and host biogeography matter for understanding the phylogeography of a parasite

The co-evolution between hosts and parasites has long been recognized as a fundamental driver of macro-evolutionary patterns of diversification. The effect of co-differentiation on parasite diversification is, however, often confounded by underlying geographic patterns of host distribution. In order to disentangle the confounding effects of allopatric versus host speciation, the mitochondrial cytochrome b (cyt b) gene was sequenced in seventy individuals of the parasitic nematode genus Heligmosomoides sampled in the six Apodemus mice species common in the western Palearctic region. The nuclear internal transcribed spacers (ITS) 1 and 2 were also sequenced in fifteen parasites to confirm the mitochondrial data. All lineages differentiated according to a geographic pattern and independently from the sampled host species. This suggests that host speciation did not involve concurrent parasite speciation. However, the geographic distribution range of some parasite lineages mirrors that of A. sylvaticus lineages in SW Europe, and that of A. flavicollis lineages in the Balkans and in the Middle East. Thus, regional co-differentiation likely occurred between the parasite and the two sister Apodemus hosts in different parts of their distribution range. We suggest that differences in regional abundances of A. sylvaticus and A. flavicollis are responsible for generating this pattern of regional co-differentiation. This study highlights the importance of integrating both geography and biogeographic information from potential hosts to better understand their parasite phylogeography.
