In order to test the significance of geographical isolation and/ or karyological differences in microevolutionary processes at the intraspecific level we used restriction enzymes and partial sequencing to study the polymorphism of the mtDNA D-loop control region in ten Greek populations. An overall high rate of both inter- and intrapopulation polymorphism was observed. The mtDNA diversity was unevenly distributed so that most of the populations studied were very similar and closely related, and only a few of them were clearly differentiated from the others. The mtDNA analysis failed to reveal any clear variation pattern that could be correlated with karyotypic forms or geographical proximity of the populations studied. Instead, the mtDNA phylogeny gave evidence in support of the coexistence of non-polymorphic (2n = 44) and polymorphic (2n < 44) karyotypic forms within the ancestral Greek M. (T.) thomasi stock. Interestingly, only one population (Agios Stefanos) seemed to significantly diverge from all the others in both methods used, forming a well-supported paraphyletic clade. Allozymic studies have already reported similar results, corroborating the genetic peculiarity of this population. © 2005 The Linnean Society of London.10aD-loop10aKaryotypic forms10aMammalia10aphylogeny10aRFLPs10asequencing1 aThanou, E.1 aFraguedakis-Tsolis, S.1 aChondropoulos, B. uhttps://icgf.myspecies.info/content/mtdna-variation-and-evaluation-phylogenetic-relationships-among-karyotypically-polymorphic02300nas a2200253 4500008004100000245004500041210004500086260001200131300001200143490000700155520158000162653002601742653001601768653001301784653002801797653001401825653002501839653003901864653002001903100001501923700001701938700001701955856007401972 2005 eng d00aChromosomal variation in the house mouse0 aChromosomal variation in the house mouse c2005/// a535-5630 v843 aAlthough the standard karyotype of the western house mouse, Mus musculus domesticus, consists entirely of acrocentric chromosomes, there are 97 distinct 'populations' that are characterized by various combinations of metacentric chromosomes that have arisen by Robertsonian (Rb) fusions and whole-arm reciprocal translocations (WARTs). In this review we discuss the processes behind the origin and fixation of these rearrangements and then present a unified list of all known metacentric populations and evaluate their phylogenetic relationships. Eleven independent phylogeographical 'systems', each consisting of 2-25 metacentric populations, were identified in Scotland, Denmark, Northern Europe-Northern Switzerland, Southern Switzerland, Northern Italy, Croatia, Spain, Central-Southern Italy, Peloponnesus, Mainland Greece and Madeira. There are six isolated metacentric populations that do not belong to any of these systems. To generate phylogenies of the metacentric populations within each system, we determined those outcomes with the fewest steps regarding accumulation of metacentrics by Rb fusions, WARTs and zonal raciation and taking into account geographical proximity. These phylogenies should be viewed as working hypotheses that will be refined with further chromosomal and molecular data and improvements in methods of phylogenetic reconstruction.

In the present paper we test whether (i) differential evolution of two mitochondrial genes or (ii) cryptic diversity can better explain conflicting results of two recently published molecular phylogenies on the same set of species of long-eared bats (genus Plecotus). We sequenced 1714 bp of three mitochondrial regions (16S, ND1, and D-loop) of 35 Plecotus populations from 10 European countries. A likelihood ratio test revealed congruent phylogenetic signals of the three data partitions. Our phylogenetic analyses demonstrated that the existence of a previously undetected Plecotus lineage caused the incongruities of previous studies. This lineage is differentiated on the species level and lives in sympatry with its sister lineage, Plecotus auritus, in Switzerland and Northern Italy. A molecular clock indicates that all European Plecotus species are of mid or late Pliocene origin. Plecotus indet. was previously described as an intergrade between P. auritus and Plecotus austriacus since it shares morphological characters with both. It is currently known from elevations above 800 m a.s.l. in the Alps, the Dinarian Alps and the Pindos mountains in Greece. Since we could demonstrate that incongruities of two molecular analyses simply arose from the mis-identification of one lineage, we conclude that molecular phylogenetic analyses do not free systematists from a thorough inclusion of morphological and ecological data. © 2002 Elsevier Science (USA).
