New species, revision, and phylogeny of Ronzotherium Aymard, 1854 (Perissodactyla, Rhinocerotidae)
(2021)
Ronzotherium is one of the earliest Rhinocerotidae in Europe, which first appeared just after the Eocene/Oligocene transition (Grande Coupure), and became extinct at the end of the Oligocene. It is a large-sized rhinocerotid, with a special position in the phylogeny of this group, as being one of the earliest-branching true Rhinocerotidae. However, its intra-generic systematics has never been tested through computational phylogenetic methods and it is basically unknown. Its taxonomical history has gone through numerous complications, and thus we aim to provide here a complete revision of this genus, through phylogenetic methods. After a re-examination of all type specimens (five supposed species) as well as of most well-preserved specimens from all over Europe and ranging through the complete Oligocene epoch, we performed a parsimony analysis to test the position of some problematic specimens. According to our results, five species can be distinguished, Ronzotherium velaunum (type species), R. filholi, R. elongatum and R. romani as well as a new species: R. heissigi sp. nov. We also drastically re-interpret its anatomy and show that the ‘short-limbed’ “Diaceratherium” massiliae, described from Southern France, can be considered as a junior synonym of R. romani. Finally, we exclude the Asian species “Ronzotherium” orientale and “Ronzotherium” brevirostre from Ronzotherium and we consider R. kochi as a junior synonym of R. filholi.
The adoption of a consistent alien species pathways categorization, hierarchy and terminology is crucial for increasing the interoperability of different online databases. In the present paper the European Alien Species Information Network (EASIN) classification system of pathways is compared and discussed with the classification scheme recently published by the Convention on Biological Diversity (CBD). Although the main pathway categories of the two classifications overall match, there are substantial differences in their subcategorization, with EASIN including 20 pathway subcategories while CBD considers 44 subcategories. In most cases, each EASIN subcategory pathway can correspond to two or more CBD subcategories. About 5,500 species listed in EASIN do not match directly with the CBD pathway subcategories, most of which are terrestrial invertebrates. Aiming at achieving synchronization between the two classification systems and at facilitating the access to information to researchers and policy makers, EASIN is trying to align with the CBD pathway classification scheme. This alignment process requires the involvement of a large number of experts, especially from the terrestrial realm, and the adoption of commonly accepted definitions of the CBD pathways.
Forest wildflowers bloom earlier as Europe warms: lessons from herbaria and spatial modelling
(2022)
Today plants often flower earlier due to climate warming. Herbarium specimens are excellent witnesses of such long-term changes. However, the magnitude of phenological shifts may vary geographically, and the data are often clustered. Therefore, large-scale analyses of herbarium data are prone to pseudoreplication and geographical biases.
We studied over 6000 herbarium specimens of 20 spring-flowering forest understory herbs from Europe to understand how their phenology had changed during the last century. We estimated phenology trends with or without taking spatial autocorrelation into account.
On average plants now flowered over 6 d earlier than at the beginning of the last century. These changes were strongly associated with warmer spring temperatures. Flowering time advanced 3.6 d per 1°C warming. Spatial modelling showed that, in some parts of Europe, plants flowered earlier or later than expected. Without accounting for this, the estimates of phenological shifts were biased and model fits were poor.
Our study indicates that forest wildflowers in Europe strongly advanced their phenology in response to climate change. However, these phenological shifts differ geographically. This shows that it is crucial to combine the analysis of herbarium data with spatial modelling when testing for long-term phenology trends across large spatial scales.
Der Beitrag vergleicht verschiedene Europa-Konzeptionen prominenter österreichischer Schriftsteller der Zwischenkriegszeit, die ganz unterschiedlich begründet sind: Während Hugo von Hofmannsthals Diagnose in erster Linie ästhetisch argumentiert, sind Stefan Zweigs Europa-Essays primär gesinnungsethisch motiviert. Demgegenüber bemüht sich Robert Musil um eine anthropologisch-verantwortungsethische Beweisführung.
This revision concerns a small group of Western Palaearctic Copris species (Coleoptera: Scarabaeoidea:
Scarabaeidae) distinguished by having three lateral teeth on the foretibae. According to the literature, this group consists of four taxa: Copris armeniacus Faldermann, 1835, C. felschei Reitter, 1892, C. pueli Mollandin de Boissy, 1905 and C. umbilicatus Abeille de Perrin, 1901. Copris armeniacus is herein deemed a species inquirenda, and C. felschei, for which a neotype is designated, is deemed valid. Copris umbilicatus is recorded for the fi rst time from Turkey. A key to all species of the genus Copris known from the Western Palaearctic is provided. Variability of the cephalic and pronotal armature, and morphology of the parameres are illustrated.
Weiträumige Kontaktnetzwerke sorgen für Verbreitung und Transfer von Wissen und Gütern sowie von kulturellen Werten. Der Transport von Lasten und Menschen kann als einer der wichtigsten Eckpfeiler solcher Austauschsysteme gesehen werden. Daher dürften die Suche nach Transportmöglichkeiten und die Entwicklung geeigneter Vehikel in der menschlichen Gedankenwelt seit jeher fest verankert sein. Die hier vorliegenden Beiträge basieren auf den Vorträgen der Tagung „Transporte, Transportwege und Transportstrukturen“ der Arbeitsgemeinschaft Bronzezeit und des Sonderforschungsbereiches 1070 RessourcenKulturen. Sie fassen im archäologischen Befund der Bronzezeit vorhandene Evidenzen zu Transportwegen und -fahrzeugen sowie Aussagen zu Infrastruktur nicht nur zusammen, sondern ergänzen diese um zahlreiche wissenswerte Aspekte. Was können diese Befunde über die Transportvehikel und ihre Bedeutung aussagen? Welche Eigenschaften wiesen diese auf? Handelt es sich bei den Fundstücken um abgenutzte oder mutwillig zerstörte Fahrzeuge bzw. Teile von solchen? Welche Implikationen auf technologischer und sozialer Ebene lassen sich mit den Befunden verbinden? Wie muss man sich die bronzezeitliche Infrastruktur in unterschiedlichen Regionen vorstellen? Inwiefern bildeten Verkehrswege und Austausch eine Ressource? Der detaillierten Beantwortung dieser Fragen ist dieser Band gewidmet, woraus eine übergreifende Zusammenschau von Funden, Befunden und Theorien entstanden ist.
