Revision of Trogulidae Sundevall, 1833 (Arachnida: Opiliones)

The relationship and phylogeny of the western Palearctic harvestmen family Trogulidae is investigated. The traditional system of seven genera and approximately 40 species appeared to be artificially composed but a phylogenetic approach and a comprehensive revision has long been sought after. Species are poorly characterised due to their uniform morphology and species evaluation is furthermore complicated by the variability of the few characters used for species delineation. To meet these demands a molecular genetic analysis is accomplished using the nuclear 28S rRNA gene and the mitochondrial cytochrome b gene. This analysis incorporates most genera and species of Trogulidae as well as a comprehensive set of Nemastomatidae and Dicranolasmatidae as outgroup taxa. Phylogenetic results of Bayesian analysis, Maximum Parsimony, Maximum Likelihood and Neighbor Joining are compared with distributional data, morphological characters and results of canonical discriminant analysis of morphometric characters and general congruence of these data sets is shown. To demonstrate the applicability of this method the revision of two species-groups within Trogulus is set out in detail. The Trogulus hirtus species-group and the Trogulus coriziformis species-group are revised. The former is in the central and north-western Balkan Peninsula. T. tricarinatus ssp. hirtus is raised to species level and four new species are described (T. karamanorum [man.n.], T. melitensis [man.n.], T. pharensis [man.n]; T. thaleri [man.n.]). The Trogulus coriziformis species-group is confined to the western Mediterranean area. T. coriziformis, T. aquaticus are re-described, T. cristatus and T. lusitanicus are re-established and four species are described as new (T. balearicus, T. huberi, T. prietoi, T. pyrenaicus). In both species-groups two further cryptic species probably exist but were not described. The species groups are shown to represent different phylogenetic levels and this information is used for the revisional work on the genus Trogulus as well as for the generic system of Trogulidae. Family status of Dicranolasmatidae is rejected and Dicranolasma is shown to be best incorporated within Trogulidae. Calathocratus, Platybessobius and Trogulocratus appear to be polyphyletic and are best to be united within Calathocratus, the oldest name of this set. The cryptic diversity within Trogulidae, especially in Trogulus and the composed genus Calathocratus rates to 150-235% and is thereby remarkably high for a group of the generally well researched European fauna. Genetic features of the group such as heteroplasmy, the possibility of major gene rearrangements and usability of the cytochrome b gene for phylogenetic studies in Opiliones are outlined.

Evolution of the sexual reproduction in Veronica (Plantaginaceae) : phylogeny, phylogeography and invasion

Die geschlechtliche Fortpflanzung ist ein universelles Merkmal und erlaubt es genetische Variation innerhalb von Blütenpflanzen zu schaffen. Die Evolution der sexuellen und reproduktiven Systeme wurde hier auf mehreren zeitlichen Ebenen, in verschiedenen Arten von Lebensraum studiert und mit fast allen möglichen Methoden im Labor, im Gewächshaus sowie im Feld untersucht. Drei Hauptteile sind in dieser Arbeit enthalten und entsprechen jeweils einem unterschiedlichen Niveau der Zeit: Gattung, Untergattung und Arten. Der erste Teil zeigt, dass die PO-Verhältnisse Untersuchungen systematisch in jeder Pflanzen-Gattung oder Untergattung untersucht werden müssen. Dieses güngstige, schnelle und leistungsstarke Werkzeug kann eine Vielzahl von Informationen über die Modi der Pflanzenreproduktion produzieren, ohne die Verwendung von teuren und langen Experimenten. Darüber hinaus könnte diese Maßnahme auch ergänzende Daten über die Taxonomie dieser untersuchten Gruppen geben. Das zweite Kapitel befasst sich mehr mit der Taxonomie der Ehrenpreis(Veronica)-Arten als die beiden anderen und zeigt, dass verschiedene Ereignisse der interspezifischen Reproduktion in einem der Hotspots der Artenvielfalt in Europa (der Balkan-Halbinsel) auftreten. Die Ergebnisse zeigen, dass morphologische und genetische Daten inkongruent sind und die Analyse der Taxonomie dieser Arten oder Unterart schwierig ist. Das letzteKapitel erzählt die Geschichte einer erfolgreichen Invasion, die während des letzten Jahrhunderts in Europa ablief trotz der Tatsache, dass die Arten obligate Fremdbefruchter sind und dass keine Samen-Produktion in der Region beobachtet wurde. Dieses Manuskript erläutert den Weg der Pflanze, um die “Baker-Regel“ zu umgehen. Diese Regel besagt, dass selbst-inkompatible Arten erfolgloser bei der Invasion neuer Lebensräume sind. Dennoch schafft es die hier untersuchte Art einen großen Teil der europäischen Rasen zu bevölkern und zeigt dabei genetische und morphologische Veränderungen auf diesem Weg.rnSchließlich wird in diesen drei verschiedenen Papieren versucht, die Verbindung zwischen der Mikro-und Makroevolution in der geschlechtlichen Fortpflanzun in Ehrenpreis (Veronica) unter Betracht verschiedener sexueller Systeme und der Stammesgeschichte, sowie der Migration zu klären.

Distinct lake level lowstand in Lake Prespa (SE Europe) at the time of the 74 (75) ka Toba eruption

Abstract. The 74 (75) ka Toba eruption in Sumatra, Indonesia, is considered to be one of the largest volcanic events during the Quaternary. Tephra from the Toba eruption has been found in many terrestrial and marine sedimentary deposits, and acidity peaks related to the eruption have been used to synchronize ice core records from Greenland and Antarctica. Seismic profiles and sedimentological data from Lake Prespa on the Balkan Peninsula, SE Europe, indicate a lake level lowstand at 73.6±7.7 ka based on ESR dating of shells. Tephrostratigraphy, radiocarbon dating and tuning of the total organic carbon content with the NGRIP isotope record, corroborate that the lake level lowstand was a short-term event superimposed on the general cooling trend at the end of MIS 5, most likely at the onset of the Greenland Stadial GS- 20. Acknowledging that tectonic events or karst processes could have triggered this lake level lowstand, the chronological correspondence between the lowstand and the Toba eruption is intriguing. Therefore a Toba-driven short-term shift to aridity in the Balkan region, leading to lake level changes and triggering spatial expansion events in one of the lake’s most abundant benthic species, the carino mussel Dreissena presbensis, cannot be excluded.
