Cím:Multilevel studies on the two phenological forms of Large Blue ( Maculinea arion ) (Lepidoptera: Lycaenidae) / Judit Bereczki, János P. Tóth, Gábor Sramkó, Zoltán Varga
Dátum:2014
ISSN:0947-5745
Megjegyzések:The main goal of our research was to study comprehensively the differences between the two phenological forms of the socially parasitic and globally threatened Large Blue (Maculinea arion)in the Carpathian Basin using four character sets (mitochondrial sequences, allozymes, male genitalia and wing morphometrics). Comparative analyses of distance matrices, phylogenetic trees and ordination patterns have been applied. The genetic and morphometric patterns revealed by our studies were disordant. While we experienced a significant differentiation between the 'spring' and 'summer type' of M. arion in both wing and genital traits, the two phenological forms did not show any genetic differentiation on two mitochondrial loci and in allozymes. At the same time, all individuals were infected by Wolbachia. Although certain wing traits may not represent reliable tracers of phylogeny because of the particular adaptive significance, the wing characteristics involved in our research are probably determined genetically. Additionally, the significant differentiation of male genitalia also indicates incipient prezygotic isolation arising from phenological differentiation between the 'spring' and summer arion'. It is possible that all extant differences between the two forms are attributable to (1) different host-ant use, (2) incipient speciation, (3) cytoplasmatic incompatibility (CI) by Wolbachia or the combination of these factors. In addition, discordant results indicate that the combined use of different approaches and data sets is strictly necessary to clarify systematic and evolutionary relationships.

Cím:Phylogeographic patterns of steppe species in Eastern Central Europe: a review and the implications for conservation / Łukasz Kajtoch, Elżbieta Cieślak, Zoltán Varga, Wojciech Paul, Miłosz A. Mazur, Gábor Sramkó, Daniel Kubisz
Dátum:2016

Megjegyzések:The phylogeography of species associated with European steppes and extrazonal xeric grasslands is poorly understood. This paper summarizes the results of recent studies on the phylogeography and conservation genetics of animals (20 taxa of beetles, butterflies, reptiles and rodents) and flowering plants (18 taxa) of such, "steppic" habitats in Eastern Central Europe. Most species show a similar phylogeographic pattern: relatively high genetic similarity within regional groups of populations and moderate-to-high genetic distinctiveness of populations from currently isolated regions located in the studied area. This distinctiveness of populations suggests a survival here during glacial maxima, including areas north of the Bohemian Massif-Carpathians arc. Steppic species generally do not follow the paradigmatic patterns known for temperate biota (south-north "contraction?expansion"), but to some extent are similar to those of arctic-alpine taxa. There are three main groups of taxa within Eastern Central Europe that differ in their contemporary distribution pattern, which may reflect historical origin and expansion routes. Present diversity patterns of the studied steppic species suggest that they share a unique genetic signature and distinct assemblages exist in each of the now isolated areas rich in steppic habitats. At least some of these areas probably act as present "interglacial refugia" for steppic species. This study strongly supports the need to protect steppic species throughout their entire ranges in the region, as the continuous destruction of steppic habitats in some areas may lead not only to the disappearance of local populations, but also to the extinction of unique evolutionary units.

Cím:Range?wide phylogeography of the fightless steppe beetle Lethrus apterus (Geotrupidae) reveals recent arrival to the Pontic Steppes from the west / Gábor Sramkó, András Kosztolányi, Levente Laczkó, Rita Rácz, Lajos Szatmári, Zoltán Varga, Zoltán Barta

Megjegyzések:The Eurasian Steppe belt is one of the largest biomes in the Northern Hemisphere. We provide here a range-wide phylogeography of the fightless steppe beetle Lethrus apterus that inhabits the western part of the Steppe belt through the study of population-level variance of mitochondrial cytochrome oxidase I sequences and nuclear microsatellites. We detected a concordant geographic structure of genetic data with a signifcant isolation-by-distance pattern. We found more genetic variation in the western part of the area and identifed Northern Bulgaria and the Pannonian Basin as possible refugia. Genetic clusters were separated by main rivers in the eastern part of the area. This implies west-to-east colonisation and argues for an evolutionarily recent arrival of this species to its current main distribution area, the Pontic Steppes. This contradicts the classical biogeographical wisdom that assumed an east-to-west colonisation pattern.

Cím:Phylogenetic relationships in the genus (Coleoptera: Geotrupidae) reveal contrasting evolutionary history in Europe / János P. Tóth, Judit Bereczki, Rita Rácz, Zoltán Varga, Zoltán Barta, Gábor Sramkó
Dátum:2019
ISSN:0307-6970
Megjegyzések:In this study we analysed for the first time the phylogenetic relationshipsamong the EuropeanLethrusspecies based on mitochondrial (COI, 16S) and nuclear(H3, wingless) markers. The phylogenetic inference based on these genes indicated thatthe EuropeanLethrusspecies form a monophyletic group with two main lineages. Oneof them is distributed in the central part of the Balkan Peninsula (North Macedonia,northwestern Greece and southwestern Bulgaria) and includes five species (L. perun,L. raymondi,L. strymonensis,L. halkidikiensisandL. elephas). Three species of theother clade (L. schaumii,L. aresandL. schneideri) occur in the eastern part of the BalkanPeninsula (southeastern Bulgaria and northeastern Greece) while its fourth member,L. apterus, could colonize much larger areas in central and eastern Europe. Despite itslarge geographic distribution,L. apterusproved to be a single species. By contrast, wefound strong intraspecific differentiation in bothL. schaumiiandL. halkidikiensisinspite of their restricted distribution. Surprisingly, two highly divergent mitogroups werealso detected within a singleL. schneideripopulation. As the microsatellite markersdid not show any differentiation between them, this finding is likely to be accountedfor by a unidirectional hybridization event. These findings highlight that phylogeneticstudies or species descriptions should not be based on mitochondrial markers alone. Ourstudy clearly demonstrates that allopatric speciation is the most important speciationmechanism in the European species of the genusLethrus, although we also hypothesizethat other well-known factors, such as hybridization or the glacial-interglacial dynamics,could significantly affect the speciation patterns of certain lineages.

Cím:Relationships within the Melitaea phoebe species group (Lepidoptera: Nymphalidae): new insights from molecular and morphometric information / Tóth János Pál, Bereczki Judit, Varga Zoltán, Rota Jadranka, Sramkó Gábor, Wahlberg Niklas
Dátum:2014
ISSN:0307-6970
Megjegyzések:The genus Melitaea consists of about 80 species, divided into ten species groups, which are all restricted to the Palaearctic region. The Melitaea phoebe group was defined by Higgins based on morphological characters such as wing pattern and genital structures. According to his iterpretation, the M.phoebe group included seven species:M.phoebe, M.sibina,M.scotosia,M.aetherie,M.collina, M.consulis and M.turkmanica. The taxonomy of the phoebe species group has been poorly resolved and recent results on the species composition within the group suggest the need for are-evaluation. In this study molecular sequences (5985 bp) including one mitochondrial (COI) and up to six nuclear (CAD,EF-1alfa, GAPDH, MDH,RpS5 and wingless) generegions from 38 specimens of theMelitaea phoebespecies groupsensuHiggins andsome closely related taxa from the Palaearctic region were analysed. The possibleevolution of the processus posterior of the male genitalia was also reconstructed based ona shape mapping technique. The analysis of the combined data shows a very clear patternand almost all relationships are highly supported. Based on the combined Bayesian treeand the shape of the processus posterior of the male genitalia, four main groups arerecognised: (i)collinagroup, (ii)arduinnagroup, (iii)aetheriegroup and (iv)phoebegroup. The status ofM.ornata,M.zagrosiandM.scotosiaas species is confirmed, andthe results also indicate thatM.telona(s.s.) from Israel is a separate species
