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.
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.
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.
Thirty-seven alien plant species, pre-identified by horizon scanning exercises were prioritised for pest risk analysis (PRA) using a modified version of the EPPO Prioritisation Process designed to be compliant with the EU Regulation 1143/2014. In Stage 1, species were categorised into one of four lists – a Residual List, EU List of Minor Concern, EU Observation List and the EU List of Invasive Alien Plants. Only those species included in the latter proceeded to the risk management stage where their priority for PRA was assessed. Due to medium or high spread potential coupled with high impacts twenty-two species were included in the EU List of Invasive Alien Plants and proceeded to Stage 2. Four species (Ambrosia trifida, Egeria densa, Fallopia baldschuanica and Oxalis pes-caprae) were assigned to the EU Observation List due to moderate or low impacts. Albizia lebbeck, Clematis terniflora, Euonymus japonicus, Lonicera morrowii, Prunus campanulata and Rubus rosifolius were assigned to the residual list due to a current lack of information on impacts. Similarly, Cornus sericea and Hydrilla verticillata were assigned to the Residual List due to unclear taxonomy and uncertainty in native status, respectively. Chromolaena odorata, Cryptostegia grandiflora and Sphagneticola trilobata were assigned to the Residual List as it is unlikely they will establish in the Union under current climatic conditions. In the risk management stage, Euonymus fortunei, Ligustrum sinense and Lonicera maackii were considered a low priority for PRA as they do not exhibit invasive tendencies despite being widely cultivated in the EU over several decades. Nineteen species were identified as having a high priority for a PRA (Acacia dealbata, Ambrosia confertiflora, Andropogon virginicus, Cardiospermum grandiflorum, Celastrus orbiculatus, Cinnamomum camphora, Cortaderia jubata, Ehrharta calycina, Gymnocoronis spilanthoides, Hakea sericea, Humulus scandens, Hygrophila polysperma, Lespedeza cuneata, Lygodium japonicum, Pennisetum setaceum, Prosopis juliflora, Sapium sebiferum, Pistia stratiotes and Salvinia molesta).

Ein Weibchen der Springspinne Heliophanus stylifer Simon, 1878 wurde im Naturpark s'Albufera auf der Balearen-Insel Mallorca (Spanien) gefunden. Die Spezies ist neu für Europa. Außerdem wurden weitere sieben Springspinnenarten nachgewiesen, darunter mit Heliophanus apiatus, Icius hamatus und Menemerus taeniatus drei Arten erstmalig für die Balearen.
In this study, the thallus-forming Laboulbeniomycetes (Herpomycetales and Laboulbeniales) from Denmark are presented as an illustrated monograph. Sixteen species and one genus are newly described based on morphology and ecology (host association). The new genus is named Tanmaurkiella Santam. gen. nov. and includes two species: T. pselaphi Santam. gen. et sp. nov. (type species) and T. huggertii Santam. gen. et sp. nov., both on Pselaphus heisei Herbst, 1792 (Col. Staphylinidae Pselaphinae). The other 14 new species are Amorphomyces ventricosus Santam. sp. nov. on Myrmecocephalus concinnus (Erichson, 1839) (Col. Staphylinidae Aleocharinae), Cantharomyces papillatus Santam. sp. nov. on Bledius terebrans (Schiødte, 1866) (Col. Staphylinidae Oxytelinae), Cryptandromyces cryptophagi Santam. sp. nov. on Cryptophagus distinguendus Sturm, 1845 (Col. Cryptophagidae), Cryptandromyces danicus Santam. sp. nov. on Euconnus wetterhallii (Gyllenhal, 1813) (Col. Staphylinidae Scydmaeninae), Dimeromyces oculatus Santam. sp. nov. on Longitarsus luridus (Scopoli, 1763) (Col. Chrysomelidae), Euphoriomyces enghoffii Santam. sp. nov. on Leiodes rugosa Stephens, 1829 (Col. Leiodidae), Euphoriomyces smicri Santam. sp. nov. on Smicrus filicornis (Fairmaire & Laboulbène, 1855) (Col. Ptiliidae), Laboulbenia inexpectata Santam. sp. nov. on Acupalpus exiguus Dejean, 1829 (Col. Carabidae), Laboulbenia pygidicola Santam. sp. nov. on Syntomus truncatellus (Linnaeus, 1761) (Col. Carabidae), Monoicomyces brachiatus Santam. sp. nov. on Atheta sodalis (Erichson, 1837) and Ocyusa picina (Aubé, 1850) (Col. Staphylinidae Aleocharinae), Monoicomyces crassicaulis Santam. sp. nov. on Oxypoda elongatula Aubé, 1850 (Col. Staphylinidae Aleocharinae), Monoicomyces reboleirae Santam. sp. nov. on Gnypeta carbonaria (Mannerheim, 1830) (Col. Staphylinidae Aleocharinae), Monoicomyces validus Santam. sp. nov. on Atheta vestita (Gravenhorst, 1806), Aleochara grisea Kraatz, 1856, and Geostiba circellaris (Gravenhorst, 1806) (Col. Staphylinidae Aleocharinae), and Stigmatomyces thoracochaetae Santam. sp. nov. on Thoracochaeta brachystoma (Stenhammer, 1855) (Diptera Sphaeroceridae). The total number of laboulbeniaceous species from Denmark rises from 29 to 195, which means that 166 are here reported as new country records. Among these, Kainomyces isomali Thaxt. deserves special mention as it is a new European record. The same applies to nine species which are reported here for the first time after their original description. For this study, an intensive sampling programme has been realized, with 429 Danish localities screened including around 1900 collections with fungi. Two new synonymies are established: Laboulbenia acupalpi Speg. (Spegazzini 1915a) syn. nov. for Laboulbenia stenolophi Speg. (Spegazzini 1914), and Monoicomyces oxytelis Huldén (Huldén 1983) syn. nov. for Monoicomyces invisibilis Thaxt. (Thaxter 1900). The new combination Peyritschiella oxyteli (Cépède & F.Picard) Santam. comb. nov. is proposed for Rheophila oxyteli Cépède & F.Picard including neotypification, and delimitation of Peyritschiella protea Thaxt. is incorporated. Lectotypes for Laboulbenia polyphaga Thaxt. and Symplectromyces vulgaris (Thaxt.) Thaxt. are designated. Nineteen species are illustrated here with photographs for the first time. Three species: Eumonoicomyces papuanus Thaxt., Peyritschiella protea, and Stigmatomyces euconni F.Picard, which were reported from Denmark in the literature should be removed from the Danish Funga. We have examined the following types of Thaxter from FH (Farlow Herbarium, Harvard University Herbaria): Asaphomyces cholevae Thaxt., Dimorphomyces myrmedoniae Thaxt., Eumonoicomyces papuanus, Laboulbenia polyphaga, Peyritschiella protea, Rhadinomyces pallidus Thaxt., and Symplectromyces vulgaris. Ceratomyces pyrenaeus Santam. is newly recorded from USA, and this is also a new record from the American continent. Description of the genus Cryptandromyces Thaxt. has been emended to incorporate the new species here described. Morphology of the antheridium in Eumonoicomyces papuanus is studied, and the status of the genus Eumonoicomyces Thaxt. vis-à-vis Monoicomyces Thaxt. is discussed. Identification keys are provided for genera and species. In support of the additional aim of this work to serve as a reference for the study of Laboulbeniomycetes fungi in Europe, we include maps and the Appendix 1 for comparison of the known species in the ten most diverse, better studied, European countries.
Two new species of cheilostomate bryozoans are described from material preserved in museums: Cradoscrupocellaria severoi sp. nov., from Iberian Mediterranean waters, and Setosella margaritae sp. nov., from shallow waters along the Atlantic coast of Europe. Moreover, the Mediterranean species Setosella cyclopensis Rosso, Di Martino & Gerovasileiou, 2020 is reported in Iberian waters for the first time.
Prioritization of introduction pathways is seen as an important component of the management of biological invasions. We address whether established alien plants, mammals, freshwater fish and terrestrial invertebrates with known ecological impacts are associated with particular introduction pathways (release, escape, contaminant, stowaway, corridor and unaided). We used the information from the European alien species database DAISIE (www.europe-aliens.org) supplemented by the EASIN catalogue (European Alien Species Information Network), and expert knowledge. Plants introduced by the pathways release, corridor and unaided were disproportionately more likely to have ecological impacts than those introduced as contaminants. In contrast, impacts were not associated with particular introduction pathways for invertebrates, mammals or fish. Thus, while for plants management strategies should be targeted towards the appropriate pathways, for animals, management should focus on reducing the total number of taxa introduced, targeting those pathways responsible for high numbers of introductions. However, regardless of taxonomic group, having multiple introduction pathways increases the likelihood of the species having an ecological impact. This may simply reflect that species introduced by multiple pathways have high propagule pressure and so have a high probability of establishment. Clearly, patterns of invasion are determined by many interacting factors and management strategies should reflect this complexity.
