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)...

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...

The effect of niche filtering on plant species abundance in temperate grassland communities

Josep Padullés Cubino, Irena Axmanová, Zdeňka Lososová, Martin Večeřa, Ariel Bergamini, Helge Bruelheide, Jürgen Dengler, Ute Jandt, Florian Jansen, Ricarda Pätsch & Milan Chytrý
1. Niche filtering predicts that abundant species in communities have similar traits that are suitable for the environment. However, niche filtering can operate on distinct axes of trait variation in response to different ecological conditions. Here, we use a trait-based approach to infer niche filtering processes and (1) test if abundant and rare species in grassland communities are differently positioned along distinct axes of trait variation, (2) determine if these trait variation axes, as well...

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...

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,...

Wenn Gämsen Schafe ersetzen: Fallstudie zu den Auswirkungen auf die Diversität von alpinen Rasen

Stefan Widmer, Matthias Riesen, Bertil O. Krüsi, Jürgen Dengler & Regula Billeter
To study how the cessation of transhumant sheep grazing in alpine areas influences biodiversity, three study sites along a chronosequence (space-for-time substitution) were studied in the Canton of St. Gallen (Switzerland): (i) an intensively used sheep pasture (approx. 81 and 195 sheep ha-1) (SB0), (ii) a sheep pasture abandoned since five years and now used by approx. 1 chamois ha-1 (SB5), and (iii) a sheep pasture abandoned since 19 years and now used by about...

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...

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

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...
