Alpine Grasslands with Acidocline Species
2013The 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
2013The 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.

Faecal Nutrient Deposition of Domestic and Wild Herbivores in an Alpine Grassland
Science of The Total Environment, 2023The contribution of herbivores to ecosystem nutrient fluxes through dung deposition has the potential to, directly and indirectly, influence ecosystem functioning. This process can be particularly important in nutrient-limited ecosystems such as alpine systems.

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

The ecology of some alpine grasslands
1968The study of the ecology of the alpine grasslands of New Zealand is in its infancy and one of the lesser-known kinds of grassland is that dominated by the short grass Chionochloa oreophila (Petrie) Zotov. This grass lives near the upper limit of alpine vegetation, usually in hollows where snow lies late into the summer (frontis-piece).

Multifunctionality and Thresholds of Alpine Grassland on the Tibetan Plateau
Journal of Resources and Ecology, 2020Ecosystems can simultaneously provide multiple functions and services. Knowledge on the combinations of such multi-dimensional functions is critical for accurately assessing the carrying capacity and implementing sustainable management. However, accurately quantify the multifunctionality of ecosystems remains challenging due to the dependence and close

A 5‐year rotational grazing changes the botanical composition of sub‐alpine and alpine grasslands
Applied Vegetation Science, 2018AbstractAimThe implementation of Grazing Management Plans (GMP), a specific policy and management tool, aimed at enhancing farm productivity while preserving plant diversity, soil and landscape. The GMP are based on rotational grazing systems (RGS) with animal stocking rate adjusted to balance grassland carrying capacity. The aim was to test the 5‐year

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 ...Giovanni Peratoner +6 more

On community structure in high alpine grasslands
Vegetatio, 1989Previously 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.
