Local Extinctions of Plants in Remnants of Extensively Used Calcareous Grasslands 1950 –1985
Populationen und ihre Dynamik Over the last few decades changes in land use have caused a drastic decline in the area of extensively used calcareous grasslands in central Europe. The persistence ofExpand
Seed rain, seedling establishment and clonal growth strategies on a glacier foreland
Seed production, composition of the seed rain. germination, and seedling mortality, as well as vegetative growth characteristics of common pioneer plant species were studied on the foreland of theExpand
Wind dispersal of alpine plant species: A comparison with lowland species
Abstract Question: The prominent role of wind dispersal in alpine habitats has been recognized early but has rarely been quantified. The aim of this study is to compare wind dispersal under alpineExpand
Population genetic diversity of the clonal plant Geum reptans (Rosaceae) in the Swiss Alps.
In the alpine landscape most plant populations are spatially isolated due to extreme patchiness and strong natural fragmentation. We used RAPD-PCR (randomly amplified polymorphic DNA polymerase chainExpand
Small differences in arrival time influence composition and productivity of plant communities.
'Who comes first' is decisive for plant community assembly and ecosystem properties. Early arrival or faster initial development of a species leads to space occupancy both above and below ground andExpand
Old cultural traditions, in addition to land use and topography, are shaping plant diversity of grasslands in the Alps
Abstract Socio-economically motivated land use changes are a major threat for species diversity of grasslands throughout the world. Here, we comprehensively explore how plant species diversity ofExpand
Genotypic and environmental variation in specific leaf area in a widespread Alpine plant after transplantation to different altitudes
Specific leaf area (SLA) is an important plant functional trait as it is an indicator of ecophysiological characteristics like relative growth rate, stress tolerance and leaf longevity. SubstantialExpand
Seed weight increases with altitude in the Swiss Alps between related species but not among populations of individual species
Seed weight is a crucial plant life history trait, determining establishment success and dispersal ability. Especially in stressful environments, larger seeds may be selected at the expense of seedExpand
Effects of elevated CO2 and phosphorus addition on productivity and community composition of intact monoliths from calcareous grassland
Abstract We investigated the effects of elevated CO2 (600 μl l−1 vs 350 μl l−1) and phosphorus supply (1 g P m−2 year−1 vs unfertilized) on intact monoliths from species-rich calcareous grassland inExpand
The relative importance of sexual and clonal reproduction for population growth in the long-lived alpine plant Geum reptans
1 Demographic studies in natural habitats are important for understanding the life history and mechanisms of population persistence of particular species. For plants living in high-alpine habitats,Expand
