Homogenization of bryophyte species after alpine grassland restoration

Journal of Environmental Management, 2022
The causes of decreasing plant species richness include abandonment of traditional management and the spread of invasive species, even in alpine habitats. Studies on the restoration and management of alpine habitats are predominantly focused on vascular plants, although an important part of alpine vegetation and its diversity is formed by bryophytes ...

Alpine Grasslands with Acidocline Species

2013
The Dolomites are composed of calcareous rocks, but at the center of this area, in distant geological times, the Predazzo volcanic complex covered the limestones with silicate rocks. The alpine grasslands on silica are described here (an acid substrate at an elevation of 2,000–2,500 m) as well as the complicated situations that occur in the contact ...

Alpine Grasslands on Limestones and Dolomites

2013
The alpine grasslands on limestones and dolomites, at an elevation of 2,000–2,500 m, are the focal point of the vegetation of the Dolomites. This is where the highest biodiversity is concentrated, thanks to particularly favorable ecological conditions that have been brought to light precisely with this research.

Growth responses of an alpine grassland to elevated CO2

Oecologia, 1996
Alpine plant species have been shown to exhibit a more pronounced increase in leaf photosynthesis under elevated CO2 than lowland plants. In order to test whether this higher carbon fixation efficiency will translate into increased biomass production under CO2 enrichment we exposed plots of narrow alpine grassland (Swiss Central Alps, 2470 m) to ...

Quantitative ecological relationships in the alpine grassland of Lesotho*

Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1974
A survey, based on 56 000 points at 102 sampling sites in the Tsehlanyane valley of the Oxbow (Madibamatso) Dam catchment in the alpine grassland of Lesotho, indicates that the area is generally in good condition. Physiographic and floristic criteria were measured and the association between pairs of criteria statistically tested. The simple (126 spp.)

Functional diversity and grazing intensity in sub‐alpine and alpine grasslands inAndorra

Applied Vegetation Science, 2014
AbstractQuestionsHumans are altering land use and impacting grazing intensities worldwide in alpine and sub‐alpine grasslands, and functional diversity (FD) is a useful tool for predicting changes in these grassland communities and for improving biodiversity conservation.

Challenges facing alpine/ mountain grasslands

This chapter reviews the main characteristics of grasslands in mountain areas. The challenges for grassland farming are mainly related to topographic features and to productive and socioeconomical issues. These challenges strongly limit management options, which often leave grasslands as the only possible agricultural land use and livestock farming as ...

On community structure in high alpine grasslands

Vegetatio, 1989
Previously published data on production biology, energy use efficiency, nutrient availability and vulnerability were reinterpreted for the explanation of community processing and structure in high altitude grasslands of the Alps. The final goal of the approach was to present a characterization of these plant communities in generalized terms.
