Grasslands of temperate Europe in a changing world – Editorial to the 16th EDGG Special Feature in Tuexenia

Steffen Boch, Thomas Becker, Balázs Deák, Jürgen Dengler & Valentin H. Klaus
Mitglieder der Eurasian Dry Grassland Group (EDGG) und deren Vorgängerorganisationen geben seit 16 Jahren Grasland-Sonderausgaben (Special Features) in Tuexenia heraus. Das diesjährige Special Feature mit dem Titel Grasländer des gemäßigten Europas in einer sich verändernden Welt umfasst sieben Artikel, die verschiedene Aspekte der Graslandforschung beleuchten und dabei unterschiedliche Organismengruppen einbeziehen: LLUMIQUINGA et al. untersuchten Langzeiteffekte von Einsaat, Mahd und Kohlenstoffzusatz (Reduktion der Nährstoffverfügbarkeit durch Verschiebung des C/N-Verhältnis) auf den Renaturierungserfolg von pannonischem Sandgrasland auf ehemaligen...

Vegetation changes in urban grasslands over 25 years in the city of Zurich, Switzerland

Julia Kummli, Stefan Widmer, Markus Wilhelm, Jürgen Dengler & Regula Billeter
Many studies have demonstrated significant alterations in the species composition of grasslands in Central Europe over the past decades due to multiple drivers of anthropogenic environmental change. Most such studies deal with dry, acidic, wet or alpine grassland types, while little is known about changes in mesic grasslands, particularly in urban areas. To investigate the effects of anthropogenic environmental change on such grasslands, we resurveyed a selection of plots in the city of Zurich (Switzerland)...

A scientific journey through geo-ecological extremes – landscape dynamics at the lower Danube between the Black Sea and the Carpathian Volcanoes

Universität Bayreuth, Germany (1); Universität Bayreuth, Germany (2); Centrul de Ecologie Montană, România (3)

The CTC-Trail (“Coast-to-Carpathians”) is a conceptual educational geo-trail that is being created to guide visitors through a transect from the southern parts of the western Black Sea area grasslands through the steppe regions of Dobrogea and eastern Walachia to the young volcanoes of the Carpathian Mountains, highlighting aspects of natural and cultural importance along this route. The journey also spans...

Unexpected high amounts of H2 produced during serpentinization at magma-poor rifted margins

Elmar Albers , Wolfgang Bach , Marta Pérez-Gussinyé , Catherine McCammon & Thomas Frederichs
At magma-poor rifted margins, serpentinization of lherzolitic mantle rocks releases molecular hydrogen (H2) that supports chemosynthesis-based deep life. Until now, however, H2 fluxes in these systems remain largely unquantified. To help closing this knowledge gap we investigated serpentinization and H2 production using drill core samples from the West Iberia margin (Ocean Drilling Program Leg 103, Hole 637A). The mostly lherzolitic samples are strongly serpentinized, consist of serpentine with little magnetite, and are generally brucite-free. Serpentine...

Effects of different restoration treatments on long-term development of plant diversity and functional trait composition in calcareous grasslands

Stefan Hofmann, Timo Conradi, Kathrin Kiehl & Harald Albrecht
Establishment of calcareous grassland on ex-arable fields by introducing target species is one of the most frequently used methods to restore the species assemblages of this highly endangered habitat type. The present study evaluates the long-term success of calcareous grassland restoration on former arable land in the vicinity of one of the oldest nature reserves in Bavaria, the “Garchinger Heide”. The restoration experiment combined different measures like topsoil removal, transfer of freshly cut seed-containing hay...

Vegetation change in meso-xeric grasslands of the Swiss Jura Mts. over 40 years

Kévin Charmillot, Christian Hedinger, Manuel Babbi, Stefan Widmer & Jürgen Dengler
Meso-xeric grasslands have declined sharply in Central Europe during the last century. These species-rich habitats are threatened by intensification or abandonment of agricultural use, eutrophica-tion, climate change and landscape fragmentation. However, different studies in various regions of Central Europe are inconsistent in their findings about degree and direction of changes. We thus resurveyed the historical vegetation plots of the alliance Mesobromion in the Swiss Jura Mts. In 2020, we re-sampled 28 quasi-permanent vegetation plots originally...

Changes in biodiversity and species composition of temperate beech forests in Switzerland over 26 years

Eline Staubli, Jürgen Dengler, Regula Billeter & Thomas Wohlgemuth
Ongoing climate warming affects vegetation in multiple ways, although it is difficult to distinguish its influence from other drivers of vegetation change. We studied how forest vegetation in the Albiskette (canton of Zurich, Switzerland), mainly dominated by European beech (Fagus sylvatica), changed from 1993 to 2019, while the mean temperature rose by 1.5 °C. To investigate how species richness and vegetation composition had changed during these 26 years, we resampled 46 permanently marked nested-plot series...

Optimal site conditions for dry grasslands of highconservation value in the canton of Zurich, Switzerland

Performative Ding-Bedeutung: Der Stricker und sein metaphysisches Dinge-Verständnis in seiner Kleinepik. ('Von Edelsteinen', 'Der wunderbare Stein', 'Der Hahn und die Perle')

Silvan Wagner
In seiner Kleinepik behandelt der Stricker die Macht von Preziosen in kritischer, dialektischer und unterhaltsamer Art und Weise. Bislang wurde in der Forschung dabei vor allem sein aufklärerischer, magiekritischer Impetus betont. Im hermeneutischen Vergleich seiner Kleinepik zeigt sich aber, dass der Stricker durchaus an einer magischen Dimension der Dinge festhält, die sich allerdings nur im Zusammenspiel der Physis der Dinge, der Erzählungen von ihren Mächten und der weisen Performanz mit ihnen entfaltet.

High-pressure partial melting of the Moldanubian felsic granulites in the Bohemian Massif

Traditional land use, management and biodiversity of European semi-natural grasslands – Editorial to the 15th EDGG Special Feature

Steffen Boch, Thomas Becker, Balázs Deák, Jürgen Dengler & Viktoria Wagner
Seit 15 Jahren geben Mitglieder der Eurasian Dry Grassland Group (EDGG) und deren Vorgänger-organisationen Grasland-Sonderausgaben (Special Features) in Tuexeniaheraus. Das diesjährige Special Feature mit dem Titel Traditionelle Landnutzung, Management und Biodiversität von halb-natürlichem Grasland in Europa umfasst acht Artikel, die viele Aspekte der Graslandforschung beleuchten und verschiedene Organismengruppen miteinbeziehen: JANIŠOVÁ et al. (2020a) untersuch-ten den Einfluss verschiedener traditioneller Landnutzungsformen auf den Artenreichtum des extensi-ven Graslands im Apuseni-Gebirge in Westrumänien. LABADESSA et al.(2020) verglichen die Arten-zusammensetzung...

Determination of habitat requirements of the glacial relict Nuphar pumila as basis for successful (re-)introductions

Sabrina Keller, Manuel Babbi, Stefan Widmer, Jamyra Gehler, Sonja Hausmann, Christian Berg, Flavia Landucci, Patrick Schwager, Kateřina Šumberová & Jürgen Dengler
Nuphar pumilais a glacial relict, which is nowadays rare throughout Europe and red-listed in most European regions. In Switzerland only three autochthonous populations and one population of the hybrid with N. lutea (N. ×spenneriana) have survived to date, one of them in the canton of Zurich. To protect this species regionally, the canton of Zurich has commissioned the ex situ propagation of speci-mens, which then had been introduced to 37 water bodies in protected areas,...
